- Abstract:
- Since 2018, the government in Guangzhou has increased the quality and efficiency improvement of sewage collection and treatment system, abandoned the traditional concept of “building instead of management”, and established corresponding treatment countermeasures according to the characteristics of each sewage treatment system. “One plant, one policy” systematized renovation, through water balance analysis, review of sewage treatment capacity and pipe network facilities efficiency, determine the idea of improving quality and efficiency, check the external water according to the regional characteristics, and block the external water through the combination of management and engineering, and optimize the sewage treatment system. Liede sewage treatment system is the largest sewage system in Guangzhou. The problems such as high water level and low influent concentration of sewage treatment plant are particularly prominent, which are also common problems of various sewage systems. Through the systematic renovation of “one plant, one policy”, Liede sewage treatment system has achieved the goals of improving water environment quality, reducing influent water quantity and water level in the plant area, and increasing influent concentration, which provides a successful case for other sewage treatment systems.
