This article is studying the water treatment based on the groundwater artificialrecharge program in Shi Jiazhuang. The groundwater artificial recharge is also calledrecirculation. The artificial recharge is a useful method of water resources orderlyregulation. The most important fact is the water quality of the source water and therequirements of water quality is very critical. The aims of requirements are security andclogging prevention.This study used the membrane bioreactor method to treat water to guarantee therecharge security. This method is called MBR for brief and developed from the traditionalactivated sludge process. MBR is developed fast in recent years and has significant effectof TN、TP removal.The simulation of water is made based on the situ water quality in this experiment andused MBR to treat. The devices of experiment are MBR machine and the relevant, andthe devices of water quality testing is Multi-Parameter Controller from HACH and thetype is DR3900. The operating parameters are HRT、the ratio of stop driving and aerationrate. The testing indexes are COD、TP、TN and NH4-N.The conclusions are as follows: The low value of HRT could increase the CODremoval rate and the relation between COD removal and HRT value is positivecorrelation. The effect of TN removal rate is not obvious as the change of HRT. The bestvalue of ratio of stop driving is9min:3min. The aeration rate is the decisive parameter ofNH4-N removal.This experiment provide support for the groundwater recharge in Gaocheng inShijiazhuang and widen the range of water source.
