催化氧化法处理绿磺隆农药废水

PESTCIDE WASTEWATER CONTAINING CHLOROSULFURON TREATED BY ELECTROLYTE AND CATALYTIC OXIDATION PROCESS

本文以脱硫处理后的绿磺隆农药废水为研究对象，将其电解，以电解产生的ＮａＣｌＯ为氧化剂，镍的氧化物为催化剂，进行催化氧化处理、较大幅度地降低了废水的ＣＯＤＣｒ值，并且使废水具有良好的可生化处理性，然后以活性污泥法处理，使之达到了排放标准。研究了ｐＨ、时间、温度等条件对ＣＯＤＣｒ去除率的影响。

Treatment of pescide wastewater containing chlorosufuron after desulfurieation by catalytic oxidation process was studied. Through this process, COD Cr in the wastewater greatly decrased and the wastewater became degradable, reaching discharge standard after activated sludge process. The effect of acidity, electrolytic time, temperature etc. On the removal rate of COD Cr were also studied.
