Shishi Construction Tailwater Recycling Emergency Project

50,000 tons of treated sewage per day can be reused

The reporter Shi Shixun (Reporter Zhan Weizhi) learned from Shishi Municipal Administration that Shishi Central City Wastewater Treatment Plant supporting project—tailwater reuse emergency project has started construction recently.

Sewage treatment plant tail water reuse project is one of Shishi City's private real estate projects this year, with a total investment of 1.2 million yuan. It is currently under intense construction, and strives to complete it by the end of next month. The project will install 3 axial-flow pumps to pump pressurized water, and then through a 1150-meter tail water reuse pipeline, from the sewage treatment plant through Shishi Road, connect the drainage area in the East-West District, and then carry out agricultural irrigation and industrial water use. Comprehensive reuse. After the completion of the project, about 50,000 tons of water can be pumped back daily. After the reconstruction, it can reach a daily pumping capacity of 100,000 tons.

According to Shi Shi, Shi Shi Municipal Management Office, the city's domestic sewage accounts for a certain proportion in the discharge of wastewater from Shishi City. It is a pity that the waste water treated by the sewage treatment plant was discharged directly into the sea. After the tail water reuse emergency project is put into use, the sewage treatment plant will pump water back through the pumping station, and after treatment, it will be discharged into the drainage ditch in the east and west areas through the reuse pipeline. This will not only save water resources, but also be used for agricultural irrigation and industrial water use. And the environment around the dilution ditch has a positive effect.
