摘要：
综合产甲烷量与COD去除率等因素,探讨了有机磷农药中间体甲基氯化物生产废水的厌氧可生化性,并讨论了pH值以及氯离子的浓度对其厌氧可生化性的影响。实验表明:甲基氯化物厌氧可生化性较差;氯离子浓度对其可生化性影响较大,当COD为1111.1mg/L,氯离子质量浓度达10.88g/L时,基本上无厌氧降解;废水在偏碱性(pH 8.0)条件下可生化性得到改善。

Abstract:
The quantity of methane and the efficiency of COD have been used to study the anaerobic biodegradability of organic phosphorous pesticide(methyl chloride)wastewater,and the influence of pH and chlorine ion content to biodegradability are discussed.Experimental results show that:methyl chlorides wastewater has poor anaerobic biodegradability;Chlorine ion content has a lot influence on the biodegradability.When influent COD is 1 111.1 mg/L,chlorine ion content can reach 10.88 g/L,fundamentally there is no anaerobic biodegradability; the wastewater anaerobic biodegradability is improved under alkalecent condition(pH 8.0).
