污泥活性炭强化SBR法处理垃圾渗滤液的实验研究

Experimental study on treatment of landfill leachate by sludge activated carbon strengthened SBR

为了进一步处理垃圾渗滤液,试验采用污泥活性炭强化序批式间歇反应器（SBR）法进行处理,通过对比普通SBR法试验,得出投加污泥活性炭强化SBR法处理垃圾渗滤液的效果要远远高于普通SBR法。当污泥活性炭的投加量为1.2 g/L,容积负荷为0.5-1.5 kg BOD5/（m3.d）时,进水1 h,曝气10 h,沉淀1.5 h,闲置1.5 h,处理效果最好,COD的去除率达到了85%,NH3-N的去除率达到了90%。

Sludge activated carbon strengthened SBR was used in the landfill leachate treatment in order to treat landfill leachate better.Comparing treated landfill leachate by the common SBR method with sludge activated carbon strengthened SBR method,it was concluded that the treatment effect of the latter one was better than the former.When the dose of sludge activated carbon added in the reactor was 1.2 g/L,the volume load was 0.5～1.5 kg BOD5/（m3·d）,the time of watering was 1 h,the time of aeration was 10 h,the time of precipitation was 1.5 h and the time of idling was 1.5 h, the treatment effect was the best. The removal rate of COD and NH3-N was 85% and 90% respectively.
