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).
