The night has darkened, and the hour hand has pointed to early morning, but the lights are still on in Su Aijun's study. The ashtray on Su Aijun's desk is already full, and the room is filled with smoke.

Su Aijun put down the pen in his hand, pinched his eyebrows, stood up, stretched his body, and opened the window. Immediately, a fresh and cool breeze rushed in.

Su Aijun looked at the dots of lights in the distance, but his mind turned to the afternoon Standing Committee meeting.

In the afternoon, Zhao Xu'an raised concerns about how Tongyi City's future water supply will be guaranteed. Tongyi City is located on the Loess Plateau. Although the annual precipitation is not low, most of it is difficult to retain. There are five rivers in Tongyi.

The longest one is the Wuting River, which enters Tongyi from Tongchuan, then flows out of Tongyi into Pingchuan, and finally merges with the Wei River in Fengyuan, becoming the main surface runoff of Tongyi.

In the early 1980s, a reservoir was built on the upper reaches of the Wuting River. Since then, the originally wide Wuting River has become a trickle except during the rainy season. And with the economic development of Tongchuan,

Some highly polluting industrial enterprises were established along both sides of the river and gained considerable economic benefits. At the same time, a large amount of industrial wastewater was put into the Wuting River. This caused the pollution in the middle and lower reaches of the Wuting River.

In areas such as Tongyi and Pingchuan, during the non-rainy season, the surface water of the Wuting River is completely negligible.

The current industrial and agricultural water use in Tongyi is mainly groundwater. However, not long ago, Fang Mingyuan entrusted the provincial water conservancy department with the investigation results of groundwater and surface runoff in Tongyi area and put it on the desks of Su Aijun and Zhao Xu'an.

.

With Tongyi's current water resources, there is no problem in supporting the existing and under-construction industrial scale and population. But if the industrial scale doubles again and the population increases to 800,000, Tongyi's

Water resources will face the dilemma of being unable to make ends meet.

In the report, experts proposed that, on the one hand, Tongyi City should strengthen the control of water and soil erosion within the territory and try to keep rainfall from the sky within the territory. On the other hand, Tongyi City should start from now on to make better arrangements for the future use of water resources.

Come up with a plan. While looking for water, increase water conservation and water reuse.

In fact, Fang Mingyuan also talked to them about this when they took control of Tongyi City, but there was no such detail as this report. The Fang family will build a new high-yield water plant in Tongyi to satisfy the needs of urban residents.

needs. At the same time, the Fang family will also build a large-scale sewage treatment plant in Tongyi to treat industrial wastewater and residents' domestic wastewater and reuse it to ensure Tongyi's water needs.

But, as the saying goes, plans can never keep up with changes!

The speed of development of Tongyi and the influx of foreign people exceeded their best estimates in advance. Today, the permanent population in Tongyi has exceeded 400,000, of which 89,000 are foreigners. And by the end of this year

By that time, this number is likely to exceed 120,000. The rapid influx of such a large population into the urban area will put considerable pressure on Tongyi's current water supply capacity.

As the first phase of the new city is approaching completion, the issue of how to better manage water resources has also been put on the government's work agenda.

Water plants undoubtedly require funds to produce tap water, and sewage treatment plants also require funds to process sewage. Tongyi has always had a water plant established in the early 1990s to ensure water for residents in the city, but it still needs funds.

Many units and residents use well water directly. As for the sewage treatment plant, let alone Tongyi, it is a new thing that has never been heard of in Tongchuan. Therefore, the water and sewage treatment fees will cost

How to charge and how much to set the price has become a headache.

The setting was too low. The water plant and sewage treatment plant did not have enough operating funds. Either the Tongyi City Government would provide subsidies or they would have to shut down operations. Suspension was naturally impossible. Even if he agreed, Fang Mingyuan would not agree.

Otherwise, why would he invest huge amounts of money in construction? The investment in that sewage treatment plant is hundreds of millions of yuan. It is said that this is only the first phase of the project, and there will be second and third phase projects in the future until Tongyi achieves zero wastewater.

emission.

If the price is set too high, it will definitely cause dissatisfaction among the residents of Tongyi. Although in China, government officials rarely pay attention to the demands of the people within their jurisdiction, Su Aijun and Zhao Xu'an do not want to be that kind of people. The reason why they

I decided to come to Tongyi, partly because it was a rare opportunity for promotion, but also because I wanted to "serve as an official and benefit the whole country."

Therefore, how to choose this balance point is a question that needs serious consideration.

Zhao Xu'an also mentioned another thing at the meeting, that is, Tongyi can control the water pollution problem within its own territory, but water pollution from upstream is beyond Tongyi's control. Moreover, Zhao Xu'an also hopes that Tongyi can

Tongyi will need more surface runoff from the upstream reservoir, and if the discharge of industrial and residential wastewater in Tongchuan cannot be controlled, the clean water in the reservoir will also be polluted after passing through the river.

This completely loses the usable value.

However, everyone knows this truth, but it is not an easy task for the Tongchuan government to rectify the polluting enterprises within the territory and transform the river courses. Even though Tongyi is now a level higher than Tongchuan, in this kind of situation

In terms of matters, it is difficult to avoid Tongchuan acting in both ways.

Tongchuan is very poor. As a purely resource-based city, after years of mining and excavation, the underground resources are already facing depletion. However, Tongchuan still does not have a unified opinion on the direction of future urban transformation. And the solution

The problem of sewage discharge means that local governments and enterprises must increase investment in controlling environmental pollution, which will make the already stretched local finances and the already small profits of enterprises even more tight. However, this problem has

It cannot be solved by Tongyi alone. What is needed is the overall management of the entire Wuting River Basin!

Su Aijun couldn't help but sigh. It would have been better if the entire Tongchuan area, including Tongyi, had been classified as a new special zone. In this case, the use of water resources could be planned as a whole, not like it is now. Although

There is a reservoir upstream with a decent storage capacity, but it cannot utilize surface runoff at all.

"Water resources are limited and precious. This concept must be deeply rooted in the hearts of the people, so that all Tongyi people understand that water is not endless and can be squandered at will." Su Aijun wrote on the paper.

Fang Mingyuan will go to the United States this time to inspect the sewage treatment system in the United States. As a country where the prototype of sewage treatment has appeared since the 1920s, it has an operation history of nearly 80 years. Learn from others

With rich experience, we can avoid detours by removing the dregs and retaining the essence. Tongyi’s development time is limited, and there is neither time nor more funds to pay for tuition.

"Our plant processes 270,000 tons of sewage per day, making it the sewage treatment plant with the largest processing capacity in Seattle. Our treated sewage has reached the standard of being discharged directly back into the river." Nicholas Batum, chief engineer of the sewage treatment plant

He said with pride.

"So, is your treated recycled water directly discharged back into the river?" Fang Mingyuan said.

"No, no, no, that's too wasteful." Batum shook his head repeatedly. "Most of our recycled water is used for urban greening, agricultural water, industrial water and other municipal water for washing cars, flushing toilets, etc. It can not only prevent urban

The pollution of sewage to the water environment can also greatly save local fresh water resources. Only a small part will be discharged into the wetland and then into the river through the wetland. In this case, the degree of pollution to the environment can be ignored." Although he said he didn't know.

What is the origin of this young man, but with the company of Boeing Director Motie Yunus and University of Washington Chancellor Brian Bryant, Batum naturally did not dare to neglect him. Not only was he polite during the reception, but he also accompanied him personally

.And when explaining, I also tried my best to explain to him the principles of sewage purification treatment in the most understandable language.

Fang Mingyuan nodded. Although he had done his homework before coming here, and Batum explained it to him in as simple and profound a way as possible, after hearing it now, he was already dizzy.

"The most advanced sewage treatment technology in the world can now treat sewage to the point where it can be directly drank. Of course, considering the operating costs and people's psychological acceptance, sewage treatment plants rarely achieve this level.

Yes. But it is not difficult to ensure that the environment is not polluted." Batum said.

"So, Mr. Batum, can you tell me how much it costs for your country's sewage treatment plant to treat one ton of sewage?" Fang Mingyuan asked. Can sewage treatment be successfully implemented locally and persisted?

, cost is undoubtedly one of the important factors.

"It's hard to say. It depends on different regions, different sewage sources, as well as the sewage treatment technology used by the factory and the scale of the factory!" Batum pondered for a long time and said, "Most of them should be about 0.3 US dollars.

To the range of $0.50.”

Fang Mingyuan nodded. This means that converted into domestic currency, it is about between two and three yuan. Taking into account the cost of land and labor in the two countries, it can be lowered further. However, if it is not possible

The cost of operating at full load will undoubtedly be higher. Such a price is indeed a bit high for China's national conditions. No wonder in the previous life, the country built so many sewage treatment plants, and the sewage treatment capacity has been comparable to that of the United States.

Roughly equal, but the water pollution situation has not been effectively alleviated. Without sufficient financial resources, it is simply impossible to afford the operating costs of sewage treatment plants.

However, he also remembered that in the next ten years, membrane treatment technology, a key technology for advanced advanced treatment of sewage, will be widely used. At first, the high price of membranes was one of the main obstacles restricting its promotion and use.

But in the next ten years, with the development and large-scale production of new polymer membrane materials, the price of membranes has dropped by about 90%. In other words, with the development of science and technology, the treatment of sewage has

Costs will also continue to fall.

"And this also needs to take into account the degree of recycled water reuse. Generally speaking, the more serious the pollution of raw sewage, the longer the pipe network that transports recycled water, and the higher the cost of recycled water reuse. Among them, the investment in pipe network is recycled water

The main component of reuse cost usually accounts for more than 60% of the total investment in recycled water reuse. The higher the degree of recycled water reuse, the overall cost of sewage treatment will also increase from the perspective of entire water resources utilization.

Descend!" Batum explained, "For example..."

According to Batum, instead of spending great efforts to build reservoirs or construct water conservancy projects to divert water from other areas in areas where water resources are scarce, it is better to increase sewage treatment and make full use of this recycled water. Like

The total investment in this plant is nearly 300 million U.S. dollars, of which 130 million U.S. dollars is the construction cost of the recycling plant and 170 million U.S. dollars is the construction cost of the recycled water pipe network. The daily water supply capacity of the project is 270,000 tons, equivalent to the new

The available water source has been increased by 100 million cubic meters. Calculated in this way, the average water resource cost per cubic meter is a little more than three US dollars. In order to expand the water supply source, a county in California, USA, built a reservoir with a water storage capacity of 120 million cubic meters.

With an investment of US$450 million, the average cost of water resources per cubic meter is US$3.7, which is nearly US$0.5 more expensive than recycled water.

Moreover, the development of recycled water reuse has irreplaceable environmental and social benefits. If the social and environmental benefits of recycled water reuse, such as reducing sewage discharge, maintaining ecological balance, and enhancing the stability and reliability of water supply, are included in

In cost calculation, compared with other ways to expand water sources, recycled water reuse has obvious comprehensive benefit advantages.

Batum talked incessantly for more than ten minutes, and then he stopped with unfinished meaning. It was a rare opportunity to show off in front of a big shot. You must know that Motiejunas and Bryant were in Seattle.

They all belong to the elites of the upper class and have a certain say in municipal construction. Making them aware of the importance of sewage treatment and recycled water reuse will undoubtedly further ensure that the municipal government attaches great importance to the sewage treatment system.

"Engineer Batum is a top student at Harvard University and has been working in the sewage treatment plant for nearly thirty years!" At some point, Chris Bilton, the director of the treatment plant, laughed and said, "Well deserved.

Experts in this field! They are the backbone of our factory.”

"Thirty years!" Fang Mingyuan and others couldn't help but stand in awe. (To be continued...)
