平湖市古横桥水厂扩建工程调试和运行

Trail operation and performance of Guhengqiao Waterworks in Pinghu City

古横桥水厂扩建工程经前期调试后,在运行供水88d内,原水CODMn平均10.55mg/L,最高15.12mg/L,NH3—N平均2.68mg/L,最高5.31mg/L,色度平均41度,最高55度,通过生物接触氧化预处理+强化常规处理+两级臭氧—生物活性炭深度处理,出厂水中上述指标均达到卫生部《生活饮用水卫生规范》和建设部《城市供水水质标准》要求。简要介绍了工艺调试和运行情况。

The routine water purification of Guhengqiao Waterworks in Pinghu City was intensified and supplemented by advances technologies like biological pretreatment and two-stage O3 - BAC processes. At the first 88 days since it was put into operation, the quality of the outlet water of composite processes of biological pretreatment, routine purification and two-stage O3 - BAC treatment has been quite good enough to meet the requirement of the national drinking water standard. In this period, the measured parameters of raw water are mean 10.55 mg/L （maximal 15. 12 mg/L）, mean 2. 68 mg/L （maximal 5.31 mg/L） and mean 41 （maximal 55） for CODMn, NH3-N and colourity respectively. This paper gives a brief introduction of the trail operation and performance of the waterworks.
