混凝沉淀SBR活性炭过滤处理垃圾渗滤液

Landfill Leachates Treated By Composite Process of Coagulative Sedimentation-SBR-Granular Activatal Carbon Fillings Filter

采用沉淀 -SBR -活性炭过滤复合工艺对城市垃圾渗滤液进行处理 ,确定混凝、SBR和活性炭过滤的最佳参数。结果表明 ,当进水CODCr为 2 5 0 0mg/L、氨氮在 90 0mg/L的条件下 ,经该系统处理后 ,出水CODCr均在 30 0mg/L以下 ,氨氮在 2 0mg/L以下 ,CODCr去除率达 90 %以上 ,氨氮去除率达 98%以上 ,达到去除有机物和氨氮的较好效果。

Urban landfill leachates were treated by composite process of coagulative sedimentation-SBR-granular activatal carbon fillings,and optimun processed condition of the coagulation,SBR and absorption were achieved.The resulte showed that the influent with COD_(Cr)=2 500 mg/L,NH3-N=900mg/L,were reduced to less 300mg/L and less 20mg/L respectively by this process.the removal rate of COD_(Cr) and NH3-N reached more than 90% and 98%.This means that the best purification of organic and denitrification have been obtained,and this composite process is reliable and effective.
