摘　　要：采用流动床生物膜技术与石灰工艺相结合处理城市污水,结果表明,处理后的出水水质优于国家污水综合排放二级标准,具体的水质指标为COD<10mg/L,BOD5<5mg/L,SS<0 1mg/L,NH3 N<1 0mg/L,去除率分别达到95%,94%,99%,97%,能够满足火电厂循环水系统补充用水的水质要求。The municipal wastewater is treated with Bio-SAC technology and limestone. The results showed that the quality of the treated wastewater can be used as the cooling water of coal-fired power plants. The COD, BOD5, SS and NH3-N of the treated wastewater are respectively less than 10mg/L and 5mg/L and 0.1mg/L and 1.0mg/L. Their corresponding removal rates are 95%, 94%, 99% and 97%.
