摘要
有机磷农药(乐果)生产废水是一类难治理的高浓度有毒有机工业废水。在常温常压下,将原废水进行碱解预处理后,采用高效、低能耗的 SBR 生化处理再辅以絮凝沉降后处理,可使 COD_(cr)浓度平均达18万mg/l 的乐果生产废水,治理后各项技术指标达到国标 GB8978—88中规定的有机磷农药工业废水排放标准。
The production wastewater with organophosphorus pesticide(Rogor)is a organic indus- trial wastewater of high concentration and toxicity,and it is difficult to treatment this wastewater.In normal atmospheric temperature and pressure,after original wastewater of COD_(cr)180000mg/l was treatmented used alkaline hydrolysis,SBR of efficient and low power consumption and flocculating settling methods,it was came up to a set emission standard of organophosphorus pesticide industrial wastewater for every technical target in GB8978-88.
