摘要：

采用生物膜一体化设备对城市垃圾渗滤液进行处理研究。通过实验获得了最佳控制参数,即溶解氧4.5～6.0mg/L,COD进水负荷>2.4kg/(m³d),NH⁴⁺-N进水负荷>0.43kg/(m²d),温度15℃以上,在该组合条件下,系统对COD和NH⁴⁺-N去除率分别达到了88.1%和100%。

Abstract:

The urban landfill leachate has been treated by bio-membrane integrative equipment. The optimal control parameters have been obtained by experiments , namely: the dissolved oxygen is 4.5~6.0 mg/L, influent load of COD< 2.4 kg /(m³·d) and NH₄⁺-N< 0.43 kg/(m³·d) , the temperature is over 15 ℃. Under these conditions, the removal rates of COD and NH₄⁺-N could reach 88.1% and 100% respectively.

Key words: landfill leachate, waste treatment, bio-membrane
