电絮凝法处理渭北油田污水的研究

摘要

采用电絮凝法对渭北油田污水进行处理，用铝极板作为组合电极，考察了电流强度、极板间距以及电解时间等因素对浊度去除效果的影响。结果表明，在电流强度为1.5 A、电解时间为10 min、极板间距为6 cm 时，油田污水的浊度显著降低，去浊率达到95％，除油率为97％，并且具有较好的杀菌效果。%The electro-coagulation method was applied to treat Weibei Oilfield sewage.Aluminum plate was used as composite electrode,the effects of current intensity,electrode spacing and electrolysis time on turbidity removal efficiency were studied respectively.Results showed that,the turbidity of oilfield sewage was signifi-cantly decreased under the following conditions:current intensity of 1.5 A,electrolysis time of 10 min,electrode spacing of 6 cm.The removal rate of turbidity was 95%.The oil removal rate was 97%.This method had good sterilization effect.
