摘　　要：鉴于某工业园区污水处理厂需要提标改造，采用多金属焦／生物一体化催化还原工艺对二沉池出水进行深度处理中试，考察了其对COD、NH3-N等指标的去除效果。结果表明，在二沉池出水COD为110～180mg／L、氨氮为8～10mg／L的条件下，经该工艺处理后，出水COD〈60mg／L、氨氮〈5mg／L，出水水质可达到《城镇污水处理厂污染物排放标准》（GB18918--2002）的一级B标准。In order to upgrade the WWTP in an industrial park, a pilot experiment was conducted for studying the advanced treatment of the secondary effluent by the multi-metal-carbon micro-electrolysis coupled with the biological treatment process, and the removal effects of COD and NH3 - N were investi- gated. The results showed that when the concentrations of COD and NH3 - N in the secondary effluent were 110 to 180 mg/L and 8 to 10 mg/L respectively, the concentrations of COD and NH3 -N in the ef- fluent of the combined process were below 60 mg/L and 5 mg/L respectively. The effluent quality met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）.
