| 摘 要： | 以佛山沙口水厂北江水源水为进水，考察了活性炭吸附（GAC）和臭氧．生物活性炭（O3-BAC）两种深度处理方法对氨氮的去除效果。结果表明：在低氨氮浓度下，GAC和O3-BAC对氨氮的平均去除率均为40％，最大去除率均为74％，BAC处理后的出水中三氯甲烷浓度较GAC的出水浓度低，而GAC处理成本低于O3-BAC，建议优先采用GAC工艺；在高氨氮浓度时，预氯化条件下如果控制沉淀池出水余氯≤0．1mg／L，则可以采用O3-BAC工艺除氨氮，适宜的氨氮浓度范围是0．59～0．62mg／L。 |

| Abstract: | Ammonia nitrogen removal for Foshan Water Plant by both advanced treatment of GAC and O3-BAC was investigated. It was shown that, at low ammonia nitrogen concentration, average ammonia nitrogen removal rate both by GAC and O3-BAC was 40%; the maximum removal rate was 74%; chloroform concentration in effluent after treating by O3-BAC was lower than that by GAC, while treating cost by GAC was lower than that by O3-BAC. It is recommended first to adopt GAC technique, if controlling residual chlorine in effluent from sediment tank to be less than 0.1mg/L; O3-BAC process can be adopted for ammonia nitrogen removal, suitable scope of ammonia nitrogen concentration is 0.59-0.62mg/L. |
