摘　　要：DTRO浓缩液属于高盐、高COD_(Cr)废水,以铱钌极板作为阳极,分别采用钛板、铜板、镀氧化铜钛板、铁板作为阴极,对某垃圾渗滤液处理站DTRO浓缩液进行电化学氧化处理。结果表明:在COD_(Cr)、NH_(3)-N及NO_(3)-N去除率3方面,铜板处理效果要优于钛板、镀氧化铜钛板和铁板,在铜板作为阴极、极板间距为30 mm、电流密度为20 mA·cm^(-2)、电解时间2 h条件下,NO_(3)-N去除率为82.7%,去除效果良好。DTRO concentrated solution belongs to high salt and high COD_(Cr) concentration wastewater.Using iridium ruthenium electrode plate as anode,using titanium plate,copper plate,copper oxide titanium plate or iron plate as cathode,the DTRO concentrated solution of a landfill leachate treatment station was treated by electrolysis method.The results showed that the copper plate had better effects than the titanium plate,the copper oxide titanium plate and the iron plate in the COD_(Cr) removal rate,NH_(3)-N removal rate and NO_(3)-N removal rate.When the copper plate wsa used as cathode,the plate distance was 30 mm,the current density was 20 mA·cm^(-2),the electrolysis time was 2 h,the NO_(3)-N removal rate of DTRO concentrated solution reached 82.7%.
