摘要
采用三级流动式活性焦工艺处理污水厂生化出水,水料比为20 m3/t·d时,处理周期为40 d,处理出水可从《城镇污水处理厂污染物排放标准》(GB 18918-2002)中的三级排放标准提升至一级A排放标准。本工艺具有较强的耐冲击负荷能力,相对稳定的出水水质,具备良好的应用价值。
The paper focuses on the three-stage flow activated coke process which was applied to treat bio-treated wastewater. The processing cycle was 40 days when the water-coke ratio was 20 m3/t·d. The effluent quality could be upgraded from the primary standard grade three to grade A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The process had strong impact load resistance, relatively stable effluent quality and good application value.
