摘要
久效磷和亚磷酸三甲酯生产过程中产生的废水经碱解沉淀和超声气浮预处理，可降低其ＣＯＤ和毒性，提高其可生化性，再经以光合细菌为主的生化处理，可使其ＣＯＤ降至２００ｍｇ／Ｌ。
The wastewater from monocrotophos and trimethyl phosphite production are pretreated by hydrolysis under alkaline condition and then by precipitation and ultrasonic air floatation,achieving removal of part of COD,reduction of toxicity and enhancement of biodegradability of the wastewater.Finally the wastewater are treated by biological process with photosynthetic bacteria,the effluent COD is reduced to 200 mg/L.
