The official operation of Shuozhou Sewage Treatment Plant has completely ended the history of "naked discharge" of sewage in Shuozhou City. In the future, the sewage in the pipe network can reach the national secondary discharge standard after being treated layer by layer, which will not only change the environmental pollution caused by the direct discharge of sewage in our city, but also play an important role in improving the water environment in Haihe River basin and protecting the health of the people downstream. Moreover, the treated reclaimed water will also become a new reclaimed water source in our city, which can promote the sustainable utilization and development of water resources in Shuozhou City, further improve the ecological environment and urban appearance, reduce the amount of groundwater exploitation, and effectively alleviate the water shortage problem in Shuozhou City. It also laid a solid foundation for Shuozhou to build an environmentally friendly and clean eco-city as soon as possible.
