| 摘 要： | 以ｏ，ｏ－二甲氧基硫代磷酰氯生产废水为代表，在２Ｌ不锈钢高压釜中研究了有机磷农药废水湿式空气氧化预处理工艺，得到了实现有机磷、有机硫去除８０－９０％，ＣＯＤ去除６０％的工艺条件及其优化组合，工艺条件相当缓和，废水处理后，其可生化降解性显著提高，ＢＯＤ５／ＣＯＤ由０．２增至０．４－０．５。工艺条件用于处理其它几中有机磷废水取得同样好的效果。

| Abstract: | The pretreatment process of organo-phosphorus pesticides wastewaters by wet air oxidation was studied in a 2L autoclave, using the wastewater from o,o-dimethyoxy-thiophosphoryl chloride production. The optimal combinations of process conditions were ascertained to get or gano-phosphor us removal of 80-90%,COD removal of -60%.Process conditions were reson-able mild. After pretreatment the biodegradability of wastewaters was obviously enhanced, The BOD5/COD ratio was increased from 0.2 to 0.4-0.5. Good results were also obtained in applying the process conditions to the treatment of several other organo-phosphorus pesticides wastewaters. |
