目的探讨ClO2氧化法对废水中甲胺磷农药的降解效果。方法将传统活性污泥降解法和ClO2氧化法处理甲胺磷农药废水的结果进行比较,研究ClO2用量对含甲胺磷农药废水中化学需氧量（COD）值变化的影响。结果含甲胺磷农药废水中COD的去除率随着ClO2用量的增加和曝气时间的延长而稳步提高。当20 mL废水用25 mL ClO2氧化反应5 min时,COD由原来的7 697.31 mg/L降至391.2 mg/L,去除率达94.92%。经过拟合,ClO2处理甲胺磷废水的回归方程为:y=0.98x3-32.63x2-83.23x+7626.60,R2=0.98,其中x为ClO2量（mL）,y为剩余COD值（mg/L）。用传统活性污泥降解法对含甲胺磷农药废水进行204 h降解处理,COD由8 230 mg/L降至...

Objectives To investigate the effect of chlorine dioxide( ClO2) oxidation on the degradation of methamidophos in wastewater. Methods Comparing the effects of conventional activated sludge with chlorine dioxide oxidation on the treatment of methamidophos in wastewater. The effect of ClO2on methamidophos in wastewater was detected by the change of chemical oxygen demand( COD) value. Results The removal of COD in methamidophs wastewater was increased steadily with higher amount of ClO2and longer aeration time. The value of COD in 20 mL of influent methamidophs wastewater was decreased from 7 697....
