摘要
采用Ca(OH)2作为混凝剂预处理深圳市三个生活垃圾焚烧厂沥滤液。结果表明投加6g/LCa(OH)2,可将沥滤液的pH调到10.5,混凝后可以去除80%-90%的总磷和SS,再提高Ca(OH)2投加量,总磷和SS对去除率提高不明显。由于沥滤液中的氨氮、总氮和COD主要是以溶解态存在,混凝过程对总氮、氨氮和COD的去除效率较低。
Lime coagulation process has been used for pretreating the landfill leachate at three Shenzhen domestic the input of Ca（OH）2 is over 6 g/L Ca （OH）e, the removal rates of TP and SS are not improved obviously. Due to the ammonianitrogen total nitrogen and COD are soluble, the removal rates are low.
