%X Advanced wastewater treatment processes for groundwater recharge,especially processes to remove organic contaminants from secondary effluent of a sewage treatment plant were studied in this research.When the raw water was recharged directly through surface percolation without advance treatment,effluent of the soil aquifer treatment(SAT)could not meet the recommended reclaimed water quality criteria.Different treatment units and combined processes such as coagulation sedimentation,filtration,ozonation,powdered activated carbon and granular activated carbon(GAC)adsorption were compared,through which the process of GAC adsorption combined with coagulation sedimentation and sand filtration before SAT was selected as the optimum process.When the secondary effluent of municipal wastewater treatment plant was treated by this process,DOC of the effluent could decrease to less than 3mg/L and the throughput of the GAC filter could be up to 3500BV.
