[Explanation] When the sewage in the pipeline cannot be transported by gravity, a sewage pumping station must be set up. As an engineering facility for transporting sewage, it is an indispensable part of today's society.

  In the Lanzhou Lily Park, there is an inconspicuous three-story earth-yellow building, which is the Yanfutan Pumping Station.

The station lifts 110,000 tons of sewage to the sewage treatment plant every day, ensuring the normal life of more than 2 million people.

  In early March, the head of Yanfutan Pumping Station Jiang Shijun and his workers wore gas masks and entered the pumping station workshop. Accompanied by the pungent odor, they inspected the high and low voltage power distribution rooms, sewage pipelines and pumping station operations.

  Jiang Shijun, who claims to be the "care worker" of the sewage pumping station, said that although the sewage contains many toxic and harmful gases such as hydrogen sulfide, in order to ensure the uninterrupted operation of the pumping station 24 hours a day, the staff on duty need to inspect the status of key equipment and instruments every hour. , Can not tolerate the slightest sloppy.

  The sewage mainly contains toxic and harmful gases such as hydrogen sulfide, but every hour, personnel must enter (perform) inspections of high and low pressure cabinets and pipeline equipment. They cannot leave people for 24 hours. After leaving people, equipment failures will cause serious consequences. Seriously, it is basically sewage flowing into the Yellow River.

  [Explanation] Regardless of Jiang Shijun's work order, wearing a gas mask, recalling his "first experience" at work, he bluntly said that the smell was unacceptable.

  I vomited on the first day at work and couldn't accept it, and couldn't adapt to it in the pumping station.

(For a long time) Now I can't smell the smell.

  [Commentary] Jiang Shijun told reporters that although the working environment is poor and he can't even do simple movements such as rubbing his eyes at work, he is very pleased to see the yellow river becoming clearer.

  In the past two years, the water in the Yellow River has also been cleared. As soon as we walk along the Yellow River, there are more wild ducks. The phenomenon of sewage overflowing on the road has been eliminated. We are also relieved and happy.

  [Explanation] Luo Hong, Jiang Shijun’s partner, believes that sewage disposal is a chore.

Today, the application of mechanical equipment such as decontamination machines and presses has made work a lot easier.

  In the past, (work) had to go under the (pumping station). It was done manually, using a spade (to shovel the garbage) into the basket, and then use the machine to catch it. (Now) in the middle of the water, there is a decontamination machine. It Can bring trash up.

  [Explanation] Meng Qingliang, director of the Pumping Station Management and Protection Office of the Lanzhou Municipal Wastewater Treatment Supervision Center, combed the development of the pumping station and said that the speed of sewage treatment reflects the progress of urban development.

  Our sewage pumping station has gone from collecting sewage to raising 130,000 tons of sewage per day. (Explanation) The city's sewage treatment and upgrading work is developing day by day, which shows that the urbanization process is relatively fast.

  [Explanation] He Mingyang, the director of the Lanzhou Municipal Wastewater Treatment Supervision Center, said that Lanzhou has 13 sewage pumping stations, which increase the daily sewage treatment capacity of 540,000 cubic meters, which has made an important contribution to local sewage reduction.
