摘要
[目的]通过实验探讨百草枯农药废水处理的新方法。[方法]采用单因素试验确定TiO2/粉煤灰协同Fenton试剂处理百草枯农药废水的最佳条件。[结果]TiO2、H2O2与FeSO4.7H2O投加量分别为150 g/L、5 mL/L和300 mg/L,反应20 min时,脱色率为92.23%,CODCr去除率为67.61%。[结论]TiO2/粉煤灰协同Fenton试剂处理百草枯废水效率高且操作方便,有良好的应用前景。
[Aims] New method for the treatment of paraquat wastewater was investigated in this paper. [Methods] Single factor test were employed to get the optimal condition for the treatment of paraquat wastewater with TiO2-fly ash and fenton reagent. [Results] Results showed that the optimum condition was as follows： TiO2 was 150 g/L, H202 was 5 mL/L, FeSO4-7H20 was 300 mg/L, the reaction time was 20 min, the decoloration was 92.23% and the CODer removal rate was 67.61%. [Conclusions] The method had the advantages of high efficiency and easy operation. Therefore, it has a good prospect for practical application.
