| 摘 要： | 改性硅藻土对城市垃圾渗滤液处理仅限于去除渗滤液中的悬浮物.悬浮物和色度的去除率分别大于98%和96%,CODcr的去除率仅为18.1%～26.4%,而对NH3-N的去除没有任何作用.用特殊驯化过的活性污泥进一步处理改性硅藻土处理后的渗滤液,CODcr又可去除80%,NH3-N去除85%,处理废水达到垃圾渗滤液排放二级标准.

| Abstract: | Modified diatomaceous earth can only remove the suspended substances in urban landfill leachat when being used to treat these wastes, and can't remove even a little NH3-N. However, the specially domesticated activated sludge could reach a CODcr and NH3-N removal rate of 80% and 85% respectively, when being used to further treat the infiltrated liquid already treated by modified diatomaceous earth. The treated waste water could reach the landfill leachat drainage standard of class 2. |
