东莞市牛山垃圾渗滤液的治理

Landfill Leachate Treatment in Niushan

选用UASB+活性污泥法+生物接触氧化+反渗透的组合工艺处理了牛山垃圾渗滤液,使出水达到了新的《生活垃圾填埋场污染控制标准》(GB16889-2008)排放标准。结果表明:由于实际进水浓度较低和碳源不足,所以缩短生化反应时间,采用活性污泥法+生物接触氧化+反渗透的组合工艺处理牛山垃圾渗滤液并投加甲醇,补充碳源,使出水达标排放。

It was detailed in this paperthatthe effluent quality in Niushan landfill treated by the combined process ＂UASB＋ Activated sludge ＋ btologlcal contact leaehate （GB16889--2008） of China. Because the concentration and carbon source of the actual sewagewerelow,in or- der to reducethe biochemical reaction time, landfill leachate in Niushan was treated by the combined process ＂Activa-ted sludge ＋ biological contact oxidation ＋RO＂.The methanolwas used to make the effluent reach the new discharge standard in the treatment.
