- Abstract:
- Aiming at the problems of low influent concentration, large water quantity fluctuation, and high operating water level of a wastewater treatment plant (WWTP) in Maozhou River basin, four aspects are investigated and analyzed respectively, including the variation feature of water quality at main sewer nodes, wastewater quality of industrial district, interception pipes along the river, illicit connection of stormwater and sewage and interception of final outlet. Targeted implementation of sewage pipe repair and renovation, reconstruction of stormwater and sewage diversion, reconstruction of sewage interception pipes along the river and other projects were carried out. As the results of the above projects, the amount of external water such as groundwater, river and stormwater entering the sewage system has been reduced, the influent BOD5 concentration has been steadily increased, the fluctuation range of the water level in the influent pump room has been narrowed, and the collection rate of the sewage collection system has been significantly improved, which could provide reference for improving the quality and efficiency of the sewage collection system of other WWTPs.
