The bus rushed all the way and first entered the Haiming District area. At that time, Luo Tianqiang, the secretary of the Haiming District Party Committee, was so scared that he was sweating on the bus. He immediately took out his mobile phone and quickly sent text messages to some people in charge of Haiming District. , but what made him more depressed was that although his text message had been edited, when he sent it out, he found that there was no signal on his mobile phone. This discovery made his eyes widen at the time, and then he took it out again. He took out his other mobile phone and looked at the phone screen, but found that there was no signal on this phone either. This discovery made Luo Tianqiang's forehead sweat immediately.
What's going on? Why did the cell phone suddenly lose signal? Luo Tianqiang thought carefully and immediately remembered some of the things Liu Fei had done before. He secretly thought that Liu Fei had installed a cell phone signal shield in the car. instrument, directly transmitting all mobile phone signals to the screen. The purpose is very simple, that is, everyone on the bus cannot send out mobile phone signals, so as not to leak the itinerary of the entire bus fleet, but let Luo Tianqiang What was more gratifying was that the bus convoy only made a short circle in the Haiming District area, and then immediately left Haiming District and headed towards the nearby Zhengang District.
Luo Tianqiang took a long breath. However, just as Luo Tianqiang breathed a sigh of relief, the leaders in Zhengang District suddenly became nervous, with their hearts in their throats. They also took out their mobile phones one after another. I wanted to remind my subordinates, but the result was the same as Luo Tianqiang, the message could not be sent.
But soon, the leaders of Zhengang District also breathed a sigh of relief, because the bus convoy only got a little closer in Zhengang District, then drove out of Zhengang District and entered Haiming District again. This time, Luo Tianqiang's forehead was sweating again.
Time passed by, and as the bus went back and forth, it quickly approached Yinhai Cereals and Oils.
When the bus drove to the gate of Yinhai Grain and Oil, Luo Tianqiang's head felt as if he had been hit hard by a hammer. There was a buzzing sound, and stars were flying in front of his eyes. He never thought that this bus convoy would After going around and around, he actually came to Yinhai Grain and Oil Company in his area. However, what made him even more unexpected was that after arriving at the gate of Yinhai Grain and Oil Company, Liu Fei asked Deng Jiaming to take action in person, and after a little negotiation at the door , just let the whole bus drive directly into the factory area and go straight to the sewage outlet. After arriving at the sewage outlet, Liu Fei immediately asked all the officials on the bus to get off. Then, the staff of the Municipal Environmental Protection Bureau brought the portable COD Testers and various other portable testing equipment were used to measure the COD (chemical oxygen demand) and other pollution parameters of Yinhai grain and oil on site, and multiple samples were taken on site and sealed for higher-level testing.
Later, Liu Fei divided the entire team into two groups. One group was supervised by Deputy Mayor Bao Zhengtang and was mainly technical staff from environmental protection bureaus at all levels. Under the supervision of Bao Zhengtang, the team conducted on-site testing of technical indicators. The other group was Led by Liu Fei personally, including standing committee members of the Municipal Party Committee and District Party Committee, as well as officials at all levels of the Municipal Environmental Protection Bureau and the District Environmental Protection Bureau, everyone first came to the sewage treatment center of Yinhai Cereals and Oils under the leadership of Liu Fei. This is a huge comprehensive pool. The pool is divided into several areas and contains various sewage treatment equipment. The entire sewage treatment process is mainly divided into three stages. However, when Liu Fei and the others came to this sewage treatment At the center, except for the fixed tank of the sedimentation tank, all other equipment (centrifuges, sludge dehydrators, aerators, microfilters, air flotation machines, etc.) in this sewage treatment center are out of operation. As for the staff, they didn't see any of them. Especially in the office of the sewage treatment center not far from the sewage treatment tank, the door was closed and there was no one inside.
Liu Fei stood above the sewage treatment plant with everyone on his face, looking at the sewage rolling by. His face looked very serious. Liu Fei pointed at the sewage treatment plant and said: "Deputy Director Zhong Yide, you are the technical staff of the Environmental Protection Bureau. Backbone, please tell me what kind of state the Yinhai Cereals and Oils sewage treatment center is in now."
Zhong Yide saw that the sewage treatment center of Yinhai Cereals and Oils also looked very ugly. He said in a deep voice: "Secretary Liu, I believe there is no need for professionals like me to make any comments. Everyone present can see it. It turns out that the sewage treatment center of Yinhai Cereals and Oils is in a state of existence but not activated."
Liu Fei said with a gloomy face: "Is it because Yinhai Cereals and Oils does this because it can achieve the purification effect of sewage treatment?"
Zhong Yide quickly shook his head and said: "No, Secretary Liu, I can give you a little explanation on this issue. This sewage treatment is mainly divided into three levels. The first level of treatment mainly removes suspended solids in the sewage. For solid pollutants, most physical treatment methods can only meet the requirements of primary treatment. For sewage treated by primary treatment, BOD can generally be removed by about 30%, which cannot meet the discharge standards. Primary treatment is a pretreatment of secondary treatment. The second-stage treatment mainly removes organic pollutants (BOD, COD substances) in the colloid and dissolved state in the sewage. The removal rate can reach more than 90%, so that the organic pollutants can meet the discharge standards. The suspended solids removal rate can reach 95% and the water output effect is good. , The third-level treatment is mainly to further treat refractory organic matter, nitrogen and phosphorus and other soluble inorganic matter that can cause eutrophication of water bodies. The main methods include biological denitrification and phosphorus removal, coagulation sedimentation, sand filtration, and activated carbon. Adsorption method, ion exchange method and electrodialysis method, etc., the whole process is that the raw sewage that passes through the coarse grid is lifted by the sewage lift pump, passes through the grid or sieve, and then enters the grit chamber, and the sewage that has been separated from sand and water enters The primary sedimentation tank is the first-level treatment (i.e. physical treatment). The effluent from the primary sedimentation tank enters the biological treatment equipment, including the activated sludge method and the biofilm method. The reactors of the activated sludge method include an aeration tank and an oxidation ditch. etc., the biofilm method includes biological filter, biological turntable, biological contact oxidation method and biological fluidized bed. The effluent from the biological treatment equipment enters the secondary sedimentation tank. The effluent from the secondary sedimentation tank is disinfected and discharged or enters the third-level treatment and the first-level treatment. The end of treatment is secondary treatment. Tertiary treatment includes biological denitrification and phosphorus removal, coagulation sedimentation, sand filtration, activated carbon adsorption, ion exchange and electrodialysis. Part of the sludge from the secondary sedimentation tank returns to A part of the primary sedimentation tank or biological treatment equipment enters the sludge concentration tank, and then enters the sludge digestion tank. After dehydration and drying equipment, the sludge is finally utilized. Only after these three levels of treatment and passing the COD sewage detector, the sludge is qualified. Only the sewage discharge can truly meet the discharge standards, and the sewage treatment center of Yinhai Cereals and Oils in front of me is obviously out of operation. According to my visual inspection, judging from the situation in front of me, this sewage center was started once an hour ago. But it stopped soon. Judging from the current condition of these sewage treatment equipment and the traces around the entire sewage treatment plant, I am afraid that this sewage treatment center has not been in operation for a long, long time. It is conservatively estimated that it will be more than a year. time."
After Zhong Yide finished speaking, Liu Fei looked at the other Environmental Protection Bureau officials with a gloomy face and said: "Everyone, you are also officials or experts from the Environmental Protection Bureau. Do you have any objections to Comrade Zhong Yide's views? "
When other officials saw that Zhong Yide had expressed his stance, how could they dare to refute Zhong Yide's opinion? After all, although Zhong Yide was not very popular, Zhong Yide's professional and technical level was second to none in the entire Environmental Protection Agency system and belonged to Haiming City is the absolute authority in the field of environmental protection.
Seeing that no one else had any objections, Liu Fei said to everyone: "Okay, in order to verify Comrade Zhong Yide's opinion, let's go to the Yinhai Cereals and Oils Information Center and take a look at the test results displayed by their online monitors. What exactly is it like?" After speaking, Liu Fei waved his hand, and everyone swarmed towards the information center of Yinhai Cereals and Oils.
At this moment, the senior management of Yinhai Cereals and Oils had received a call from the staff at the guard duty station, telling them that Haiming City Party Committee Secretary Liu Fei had brought a large number of officials to Yinhai Cereals and Oils for inspection. Later, they received reports that Liu Fei and the others rushed directly to the sewage treatment center after entering the factory. When the senior executives of Yinhai Cereals and Oils rushed to the sewage treatment plant, they only found that Vice Mayor Bao Zhengtang and his staff were taking samples and testing. After taking pictures, collecting evidence and many other technical operations, after a brief inquiry, I learned that Liu Fei had already taken people to the information center. After hearing the news, Li Yijia, the chairman of Yinhai Cereals and Oils, immediately sweatdropped on his forehead. After falling off, he quickly led a group of men to the information center.
At this moment, Liu Fei has led people to the information center of Yinhai Cereals and Oils.
After entering the information center, Liu Fei immediately called the director of the information center, Yi Siming, and asked him to directly retrieve the sewage discharge records and various sewage monitoring data of Yinhai Cereals and Oils in the past month.
After hearing this, the director of the information center, Yi Siming, changed his expression. He hesitated for a long time before he finally managed to say: "Liu...Secretary Liu, the server we are responsible for recording monitoring data is broken."
Liu Fei's face turned cold and he said coldly: "It's broken. When did it break?"
"This...this just broke." Yi Siming began to lie.
How could Liu Fei be so easily deceived? He said calmly: "It's broken, it doesn't matter. Tell me which server is responsible for the sewage treatment center, and I will repair it for you on site. Oh, you don't have to worry, as long as you Your server is not a hardware failure, I can fix it for you on site because I graduated from Peking University majoring in computer science."
Yi Siming was so scared that his legs were weak because their server was not broken at all.
