Study on high water level operation's solution for wastewater drainage system based on hydraulic model
High water level of drainage system affects the operation efficiency of Waste Water Treatment Plant(WWTP)and endanger the safety of water environment.Focus on sewage system of Chengbei District in Luan city,the pump inlet room and related pipelines remained high water level in most of the day because of peak time for water user.Based on numerical model,time series of control rules was set for the secondary sewage pumping station by analyzing adjustable storage volumes and volumes which were needed to be adjusted.Multiple solution schemes were proposed and the best solution was chosen.The control rules for best solution was set for each pump by PLC.The result showed that time series of control rules could efficiently reduce high level opera-tion in drainage system,and enhanced the stability of inflow which could ensure the stable opera-tion of WWTP.
