摘要
研究了O3/Fenton试剂联合处理农药多菌灵废水的方法,并且考察pH值、臭氧用量、Fenton试剂投加量对处理效果的影响。实验结果表明:最优条件为废水pH值调节为9左右、臭氧用量为2.0g/L、H2O2投加量为5mL/L时,废水COD去除率达68%,BOD/COD提高到0.36。如果用接触氧化进行二级处理,可使最终出水指标达到国家一级排放标准。
Ozone-Fenton reagent were selected as oxidizer for the treatment of carbendazim in wastewater,the pH and the optimum dosage of ozone and Fenton reagent which affected the removal rate of COD were studied. According to the wastewater quality,under the optimal conditions of pH 9,ozone dosage 2.0 g/L,and H2O2 dosage 5.0 mg/L,the COD removal rate was 68.0%,and BOD/COD raised up to 0.36. If it was treated by second-treatment again using biological contacted,oxidation process,the effluent quality can meet the first order of national wastewater integrated discharge standard.
