摘要
乐果属有机磷类农药，其生产废水的ＣＯＤＣｒ、总磷、无机磷等污染物含量均较高．采用石灰乳（Ｃａ（ＯＨ）２）－碱式氯化铝（ＰＡＣ）－聚丙烯酰胺（ＰＡＭ）混凝沉淀工艺，对乐果生产废水进行预处理，获得良好的效果；通过实验确定了最佳混凝剂。
A lime milk polyaluminum chloride(PAC) polycrylamide(PAM) coagulation and deposition process is taken to pretest production wastewater of dimethoale. The suitable stirring speed and treatment time are determined by a series of experiments. The relationships between pH,the dosage of Ca(OH) 2,PAC and the removal rates of COD Cr ,total phosphorus,inorganic phosphorus are also defined. The results show that the dosage of Ca(OH) 2 and pH are primary factors to the removal rates of COD Cr and phosphorus.
