摘要：

采用微波-Fenton-活性炭组合工艺对有机磷农药混合废水进行处理。研究了废水初始浓度、初始pH、FeSO₄·7H₂O及H₂O₂投加量、微波功率及辐照时间等因素对处理效果的影响。结果表明:在一定的试验条件下,对100 mL COD为360～400 mg/L的废水,当pH为3.5,活性炭投加量为3.0 g,FeSO₄·7H₂O投加量为0.25 g,30%H₂O₂投加量为1 mL,微波功率为680 W,辐照时间为7 min时,处理后的出水COD可降至40～44 mg/L,COD去除率平均达89%。

Abstract:

Microwave-Fenton-activated carbon combined process has been used for treating organophosphorus pesticides mixed wastewater.The effects of the initial concentration,initial pH,dosages of FeSO₄·7H₂O and H₂O₂,microwave power and microwave irradiation time,etc.on organophosphorus degradation effectiveness are studied.Under certain experimental conditions,100 mL of wastewater whose COD is 360-400 mg/L is treated,when its pH is 3.5,dosage of activated carbon 3.0 g,dosage of FeSO₄·7H₂O 0.25 g,dosage of 30% of H₂O₂ 1 mL,microwave power 680 W and irradation time 7 min,the treated effluent COD can be dropped to 40-44 mg/L and the average removal rate of COD reaches 89%.

Key words: microwave-Fenton-activated carbon treatment process, organophosphorus pesticides mixed wastewater, oxidized cygon, dichlorvos
