Rebirth of science and technology academic master

2020 is destined to be an extraordinary year.

The whole country is focusing on Gangneung, a city in central China with a population of more than 10 million, and the voice of "Come on Gangneung" is so loud. Even on New Year's Eve and the first day of the Lunar New Year, the Spring Festival Gala takes a back seat, and everyone is silently praying and cheering for "Gangneung".

Scenes of touching scenes are displayed in front of people's sight, uniting the people's hearts and once again demonstrating the willfulness of the Chinese people. In the face of natural disasters, China will never avoid it, but will fight it head-on and defeat the disaster.

For the first time, the whole country is ushering in the longest Spring Festival holiday in history. For the first time, people dislike the Spring Festival holiday. Shopping malls everywhere are not open, and people are just bored at home.

The old saying that the epidemic has stopped in the wild has been repeated again, reflecting the wisdom of our ancestors. It has also made people pay attention to agriculture, rural areas and farmers again. One difference between Chinese rural areas and the West is that Chinese rural areas can achieve self-sufficiency. They are simply a complete small society. Even if they are closed for more than half a year, there will be no big problems.

China's agriculture, rural areas and farmers are not just farmers, rural areas, and agriculture, but all industries in rural areas!

Qin Yuanqing returned to the capital from Jiangling City and started another matter, that is, the application of 'Purification No. 1 Bacteria'. Qin Yuanqing thought about it and felt that if he went to acquire sewage plants and water affairs groups, it would be very cumbersome and involved It is very difficult and almost impossible for governments at all levels and private enterprises to achieve this.

The only thing that can be done is to start from the national level and establish large-scale central enterprises, so that it is not people versus public, but public versus public. In addition, large central enterprises are often at a higher level, which is also conducive to rapid completion.

Just after these years, all ten large hydropower stations have been built, and they have enough power to achieve this great feat.

With the completion of ten large hydropower stations and the completion of the first phase of ten nuclear power plants, China's power shortage has been greatly alleviated. The annual power generation has exceeded 850 million kilowatt hours. In addition, with the completion of the second phase of ten nuclear power plants Once the project starts construction, the annual power generation will further increase within a few years.

Therefore, regardless of the current financial resources or personnel, there is enough power to form a large central enterprise again.

Moreover, due to this sudden disaster this year, China's economy has been greatly affected, and overseas exports will further decline. This year's economic situation is destined to not be much better. The launch of the sewage treatment project will at least create hundreds of thousands of jobs. , and can also alleviate the pressure of economic downturn.

Thinking of this, Qin Yuanqing wrote a report and submitted it to his superiors through special channels.

Half a month later, Qin Yuanqing took the researchers from the laboratory to a common place in the suburbs called stinking ditches.

These stinking ditches are usually concentrated in the urban-rural fringe. This phenomenon exists not only in the capital, but also in other cities.

When the leaders of the environmental protection department who came with the city leaders saw the smelly ditch, their faces turned livid and their legs became weak.

For a long time, the environmental protection department has focused on cities or industrial areas, and has not paid much attention to these villages, because the main roads do not lead here, and they are surrounded by factories, warehouses, etc., with no water or ventilation, and are selectively invisible to developers. , after all, there is no development value here.

Therefore, sewage treatment is out of the question. Villagers discharge domestic and breeding sewage directly into small ditches, and the water in the small ditches flows into the rivers, making the small ditches and rivers become veritable stinking ditches.

Don’t underestimate the destructive power of rural sewage. Domestic pollutants and feces make the water black and devalued and breed bacteria. Pesticides and fertilizers make the water toxic.

In oxygen-free, toxic water, there would be no aquatic life at all.

This sewage will seep into the ground and seriously pollute the groundwater. The polluted groundwater will be pumped up, boiled and drank by rural households without water supply, creating a vicious cycle.

This was the first time that Leader Chen came here. He was stunned by the scene in front of him and his face was very ugly.

All I saw was a dark, smelly ditch with weeds and various plastic waste floating on it. Several local farmers were still using the black water in the ditch to water their vegetables as if nothing had happened.

"Are you eating this dish yourself?" Leader Chen couldn't help but ask an aunt.

This aunt obviously rarely watches the news on Beijing TV, so she doesn’t know Leader Chen at all. She just thinks he is an ordinary person, so she said: "What do you want to eat? They are all sold to the market. How can you eat so many dishes by yourself?"

"How can I water vegetables even though the water is dark?" Leader Chen frowned. He could smell the fishy smell of the water.

"What's wrong with water? It's water for vegetables, not for people!" the aunt said with contempt.

As an environmental professional, Leader Chen was speechless at this time. Ordinary farmers, limited by their education level, simply do not know that vegetables can also absorb harmful substances in black water, and these substances are eventually eaten by people.

Qin Yuanqing also sighed. This phenomenon is not an isolated case, but a common phenomenon.

In the land of China, there are more centralized vegetable, fruit, and meat production bases, which use a large amount of chemical fertilizers, pesticides, antibiotics, etc. The products produced are not eaten by oneself, but are sold to the market for others to eat. It seems that others eat them. It's none of your own business. Little did they know that when the producers went out to buy vegetables and fruits, those selling vegetables and fruits also thought the same way.

It is also true that China's food health and safety is very serious, and environmental protection and governance are urgent.

"Old leader, this time the superiors want to see the actual effect, so they will choose Beijing as the pilot. If the pilot in Beijing is good, it will be promoted to the whole country. I still need your support in this regard, old leader!" Qin Yuanqing said.

Qin Yuanqing's original idea was to establish a large central enterprise and acquire all the sewage plants and water companies in the country through the large central enterprise. This would make the whole country a game of chess, which would be easy to implement. However, after the superiors passed the study, they chose to govern on a province-by-province basis. The reason is also very good, that is, the life of local governments is not easy, especially this year, life is very tight, and some places can’t even Wages can no longer be paid.

And if it is carried out by the province, it can also increase local fiscal revenue.

Furthermore, sewage plants and water services also involve a large number of workers. In today's economic situation, everything is based on stability.

So in this case, the chosen pilot is Beijing.

"I was shocked to see this scene today. This is the malfeasance of the relevant staff. I feel very sad in my heart!" Leader Chen said: "Green mountains and green waters are mountains of gold and silver! This has been emphasized many times, but we Some staff members are still not ideologically aware enough!”

"Academician Qin, I am confident in your research results! The city will definitely cooperate with you 100%!" Leader Chen said.

Qin Yuanqing faced the researchers and the engineering team transferred from the city and began to come out with various instruments and equipment. In fact, there was a purification tank next to this smelly ditch. Unfortunately, there was too much sewage and the purification tank could not be used at all. Real purification, so that the sewage still smells bad.

It took most of the day to finally install the equipment and instruments. Then the gate was opened to let the sewage flow into the purification tank. Under the purification of 'Purification No. 1 bacteria', the water quality became clear. When it reached the water outlet, the water It's already very clear.

"Our 'Purification No. 1 bacteria' has very high temperature requirements. It needs a constant temperature of 25°C to have a one-month lifespan and normal reproduction. Once the temperature exceeds 25°C or falls below 25°C, it can survive in water for only An hour!" Qin Yuanqing explained to Leader Chen that although Leader Chen had left scientific research and turned to administration, he was a professional after all, so communication was still trouble-free: "Precipitated pollutants must be cleaned regularly every month, and then concentrated. deal with!"

"After sewage treatment, can it really meet Class III water standards?" Leader Chen asked.

Class III water means that the water is very clear and has no odor. The water can be used for drinking water after treatment at the water plant.

In fact, after so many years of development, Huaxia's sewage treatment mechanism has been relatively perfect. In large sewage treatment plants, after treatment with grill filtration, biological oxidation ditch, sedimentation tank, etc., it can already reach Class III water or Class II water. Water-like standards are directly discharged into rivers, lakes, etc. However, sewage plants are basically concentrated in cities. As for towns, there are no such sewage plants at all, because these sewage plants have great disadvantages, covering a large area, complex treatment procedures, There are many consumables and high costs, and there is simply not enough financial support to extend sewage treatment to the township and village levels.

And there is another point, that is, the unstable type of treatment can theoretically achieve Class III water, but in actual operation, it can often only reach Class IV water.

"Our laboratory has conducted many experiments, including the school's artificial lake and Shahe Reservoir. After the treatment of 'Purification No. 1 Bacteria', the water quality reached Class III water after the first process, and the water quality reached Class II water after the second process. !" Qin Yuanqing was full of confidence in this.

The 'Purification No. 1 bacteria' left the laboratory and was used to purify the water quality of the artificial lake on the Shahe Campus and the water quality of the Shahe Reservoir, and the results are very gratifying.

"In this case, I believe that within a few years, the problem of smelly ditches and sewage across the country can be eliminated!" Leader Chen then showed a smile on his face.

"This year's goal is to eliminate the smelly ditches and sewage problems in the capital city. However, in this regard, the city must allocate sufficient special funds and provide sufficient organizational guarantees!" Qin Yuanqing said with a smile.

This time, the pilot city is actually not only Beijing City, but also Qin Yuanqing also fought for his hometown Shuixian City as a pilot city. Although Shuixian City is developing rapidly, the pollution problem is also very serious, and smelly ditches are everywhere. , no one dares to swim or wash clothes in the river anymore.

And through two pilot cities, one in the south and one in the north, when the provinces want to conduct inspections, they can do so nearby without having to crowd all of them to the capital.
