摘　　要：四川某草甘膦生产企业污水处理站出水CODCr和TP指标无法达到排放标准,需要进行升级改造污水处理系统。为了减少投资和运行成本,将PFS除磷、NaClO氧化除磷和微电解除磷技术进行耦合作为草甘膦废水的深度处理工艺,详细研究了药剂投加量、反应的pH值以及停留时间对除磷效果的影响。实验和污水站现场运行结果表明,将这三种技术耦合作为草甘膦废水的末端出水处理工艺可以达到预期效果。The effluent TP and COD Cr indexes of the sewage treatment station of a glyphosate production enterprise in Sichuan cannot meet the discharge standards,so the sewage treatment system needs to be upgraded.In order to reduce the investment and operation cost,PFS phosphorus removal,NaClO oxidation phosphorus removal and micro electricity phosphorus removal technologies are coupled as the advanced treatment process of glyphosate wastewater in this study,and the effects of dosage of reagent,pH of reaction and retention time on phosphorus removal are studied in detail.The results of experiments and on-site operation of the sewage station show that the coupling of these three technologies as the terminal effluent treatment process of glyphosate wastewater can achieve the desired results.
