电子工业清洗废水是较难生物降解的工业污水之一,因此,须采用其他方法对其进行处理。文章通过室内烧杯试验研究了采用高铁酸钾氧化法处理该种废水的影响因素和方法,当该种废水的COd浓度在500~800Mg/l范围内时,调整废水PH=2左右,投加量高铁酸钾3g/l左右,并分次投加,则当反应时间超过30MIn后,其COd的去除率可达40%左右,且效果稳定。活性炭吸附可以进一步去除高铁酸钾反应出水的COd,当活性炭投加量高于10g/l,吸附反应5H时,出水COd低于100Mg/l,符合排放标准。Electronic industry cleaning wastewater is more difficult one of biodegradable industrial wastewater.Therefore,it is necessary to adopt other methods to deal with it.This study investigated the influence factors and methods of treating the kind of water by potassium ferrate oxidation through the indoor experiment by the beaker.When the COD concentration of the kind of wastewater is between 500～800mg/L,adjusting the wastewater pH=2 or so,adding the amount of potassium ferrate with 3g/L or so,fractionated dosing,and then sustaining the reaction time of more than 30min,its COD removal rate is up to about 40% with the effect of stability.The potassium ferrate reaction effluent COD can be further removed by activated carbon adsorption.When the dosage of activated carbon was higher than 10g/L and the reactionb time was 5h,the effluent COD was below 100mg/L which met emission standar
