摘要
采用填充床电化学反应器对低浓度含氰废水进行直接氧化试验。结果表明:填充床电极电流效率高,电流密度大,电解时间短;单位体积电解池的处理能力和电耗优于平板电极;对于含氰浓度低于250mg/L 的废水,采用填充床电极直接处理至排放标准。
Direct oxidation of low cyanide wastewater was carried out in packed bed electrochemical reactor.Results show that it has higher current efficency and density,shorter retention time, larger specific volumetric treatment capacity and lower energy consumption than plate electrode. For wastewater containing 150mg/L CN^-,CN^- concn.can be lower than 0.5mg/L after such treatment.
