摘要:
基于草甘膦的结构和性质,对其工业生产废水的治理与资源化进行研究.用CaCl2溶液作为沉淀剂使草甘膦生成钙盐沉淀,沉淀经PCW软化剂处理得到浓度为5%的草甘膦水溶液.探讨了废水溶液pH、CaCl2溶液使用量、盐酸及PCW软化剂加入量等因素对处理效果的影响.结果表明:在最佳工艺条件下,每100 mL废水,用15 mL CaCl2溶液(浓度为634 g/L)沉淀,过滤后的滤饼用6.2 mL盐酸处理后再经2.5 g PCW软化剂处理,得到的草甘膦溶液达到生产企业所要求的标准.该工艺草甘膦回收率达到95%,废水COD去除率大于95%,实现了草甘膦废水的资源化.
Abstract:
Based on the struc ture and property o f glyphosate, its w astew ater was treated by C aC l2 so lution. Under certa in conditions, itw as transform ed to deposit of ca lc ium sa lt wh ich would be processed to 5% g lyphosate so lution by PCW in tenerate reagent. Some factors affecting the results such as pH va lue o f the so lution, quantity of CaCl2 so lution, hydroch lo ric ac id and PCW intenera te reagent had been stud ied. The resu lts show ed that under optim ized conditions, each 100mL w astew aterw as treated w ith 15 mL C aC l2 so lution ( 634 g /L), 6. 2mL hydroch lo ric acid and 2.5 g PCW intenera te reagent in turn, and recovered g lyphosate so lution could ma tch the standard o f produc ing co rporations. In th is techn iques, high recovery e fficiency o f g lypho sate as m uch as 95% w as obta ined and rem oval rate o f COD was above 95%.
