摘要
以农药废水作为研究对象,初步研究了改性粉煤灰联合Fenton试剂处理2甲4氯钠废水时各影响因子的作用机制。试验结果表明在pH值为3,改性粉煤灰的用量300 g/L,FeSO4.7H2O与H2O2投加量为0.2 g/L和12 mL/L,反应20 min,废水CODCr去除率和脱色率达到最佳,分别为55.21%和83.35%。此法操作方便,具有处理效率高、反应速率高、成本低廉、操作方便等优点,具有较好的实际应用前景。
Pesticide waste water taken as an example, action mechanisms of affecting factors in treating MCPA-Na waste water by modified fly ash and Fenton reagent were preliminarily investigated. The results showed when the initial pH value was 3, the amount of modified fly ash was 300 g/L, FeSO4·7H2O was 0.2 g/L, H2O2 was 12mL/L, after 20 minutes of reaction time, COD_Cr removal and decolorization rate reached the optimum values, which were 55.21% and 83.35%, respectively. This method has many advantages, such as high efficiency, rapid response, low cost, and easy operation. Therefore, it has a good prospect for practical application.
