摘　　要：以重庆市某微污染地表水源为对象,考察包埋硝化菌颗粒填充率为30%的流化床-超滤联用工艺处理效果,并与传统工艺进行对比。试验结果表明,当进水氨氮为0.38~1.27 mg/L、高锰酸钾指数COD Mn为6.5~8.0 mg/L,在溶解氧DO≥2 mg/L,水力停留时间HRT=10 min条件下,包埋菌-超滤工艺出水氨氮平均浓度为0.23 mg/L,COD Mn平均浓度4.65 mg/L,平均去除率分别为66.2%和35.4%。包埋菌-超滤工艺去除氨氮效果比传统工艺高出44.2%,对COD Mn的去除效果比传统工艺高出6.3%,出水指标可达到中国《生活饮用水卫生标准》(GB 5749—2006)要求。A micro-polluted surface water source in Chongqing was taken as the study object,and the treatment effect of fluid bed-ultrafiltration combined process with 30%filling rate of embedded nitrifying bacteria particles was investigated and compared with the traditional process.The test results show that when the influent ammonia nitrogen(NH_(4)^(+)-N)is 0.38~1.27 mg/L,the COD Mn is 6.5~8.0 mg/L,under the conditions of dissolved oxygen(DO)≥2 mg/L and hydraulic retention time(HRT)=10 min,the average concentration of NH_(4)^(+)-N in the effluent of the embedded nitrifying bacteria-ultrafiltration process 0.23 mg/L,the average concentration of COD Mn was 4.65 mg/L,and the average removal rates were 66.2%and 35.4%,respectively.The effluent quality meets the requirements of China’s Sanitary Standard for Drinking Water(GB 5749—2006).
