STUDIES ON LANDFILL LEACHATES TREATED BY COMPOSITE PROCESS OF HYDROLYTIC ACIDIFICATION-SBR-CHEMICAL COAGULATION AND SEDIMENTATION

Urban landfill leachates were treated by composite process of hydrolytic acidification-SBR-chemical coagulation and sedimentation,and the optimum processed conditions of the anoxic,SBR and coagulation were achieved.The result showed that the influent with COD_ Cr= 1 720 mg/L,NH_3-N= 127.6 mg/L were reduced to 148.4 mg/L and 12.2 mg/L respectively by this process.The removal rates of COD_ Cr and NH_3-N were 91.2% and 90.4%.This means that the best purification of organic and denitrification have been obtained,and this composite process is reliable and effective.
