摘　　要：扬州头桥水厂二期工程试运行时出现了一些问题。由于一期工程在施工过程中一些构筑物设计参数发生了变更,二期工程按没有变更的图纸施工或其他原因,导致二期工程与一期工程配水不均匀;二期工程的折板絮凝池形成的矾花不密实,与水的分离效果不佳,平流沉淀池出水浊度偏高;回用水池常常溢流;取水泵房1#机座上方起重机运行不到吊装位。分析这些问题产生的原因,针对出现的问题,逐一解决。改造后,运行良好,管理方便,节省了矾耗,出厂水水质指标均满足《生活饮用水卫生标准》(GB 5749—2006)。Some problems appeared in the trial operation of the second phase project of Yangzhou Touqiao waterworks. Since the design parameters of some structures in the first phase of the project has been changed while the second phase of the project was not constructed accordingly, the distribution of raw water was not uniform between the first and the second phase of the project. Besides, the floc formed in folded-plate flocculation tank was loose and could not be separated well from water, thus the effluent turbidity was high in the flat flow sedimentation tank of the second phase. The reuse pool always overflowed, and the crane in the No. 1 pumping house could not reach the lifting position. The reasons and solutions to these problems were provided. After modification, the project has run well. The management of the project was convenient, and the dosage of flocculants was reduced. The effluent water quality could meet the requirements of Standards for Drinking Water Quality（ GB 5749 - 2006 ）.
