| 摘 要： | 以重庆某水库水为对象,考察了曝气生物滤池-超滤组合工艺对高氨氮、高有机物原水中污染物的去除效果。结果表明:试验装置运行期间,进水CODMn平均值为7 mg/L,出水CODMn平均值为3.5 mg/L,CODMn平均去除率为50.0%;进水氨氮平均值为0.65 mg/L,出水氨氮平均值为0.12 mg/L,氨氮平均去除率为81.5%。组合工艺对CODMn和氨氮的平均去除率较曝气生物滤池分别提高了26.9%和11.4%,较常规絮凝-沉淀工艺分别提高了20.0%和58.5%,原水经曝气生物滤池-超滤组合工艺处理后,其氨氮、CODMn均满足《生活饮用水卫生标准》(GB 5749—2006)中的相关要求。

| Abstract: | Taking a reservoir water in Chongqing as an object,removal effect of pollutants in raw water with high ammonia nitrogen and high organic matter by combined processes of BAF and UF was investigated.The results showed that average influent CODMn was 7 mg/L,effluent CODMn was 3.5 mg/L,average removal rate of CODMn was 50.0%,average influent ammonia nitrogen was 0.65 mg/L,effluent ammonia nitrogen was 0.12 mg/L,and average removal rate of ammonia nitrogen was 81.5%during the operation of the test device.Average removal rate of CODMn and ammonia nitrogen of combined processes of BAF and UF was 26.9%and 11.4%higher than that of BAF,and 20.0%and 58.5%higher than that of conventional flocculation-sedimentation process,respectively.After raw water was treated by combined processes of BAF and UF,ammonia nitrogen and CODMn of raw water met relevant requirements of National Standard for Drinking Water Quality(GB 5749—2006). |
