| 摘 要： | 嘉兴南门水厂将原普通砂滤池改造为活性炭／砂双滤料滤池，进入稳定运行期后活性炭／砂滤池可削减氨氮负荷0．70～1．30mg／L，对CODMn的去除率为15％～22％，对锰的去除率≥90％，均远高于原普通砂滤池，而制水成本仅增加约0．025元／m^3。实践证明，强化混凝-生物活性炭／砂双滤料滤池组合工艺是处理低氨氮（〈1．5mg／L）、低CODMn（4～6mg／L）、低锰（〈0．7mg／L）微污染原水的经济性选择。 |

| Abstract: | The previous common sand filter was reconstructed into activated carbon/sand filter in Jiaxing Nanmen Waterworks. Under the steady operating condition, the activated carbon/sand filter reduces NH3 - N of 0.70 to 1.30 mg/L, and has higher the removal efficiencies of CODMn and Mn than the previous common sand filter, with 15% to 22% and 90% to 100% respectively, but water treatment cost is increased only by 0. 025 Yuan/m^3. The practice shows that the combined process of enhanced coagulation and biological activated carbon/sand filter is an economic choice for treating raw water polluted by NH3 - N of less than 1.5 mg/L, CODMn of 4 to 6 mg/L, and Mn of less than 0.7 mg/L. |
