湖州城北水厂净水工艺方案的比选

Comparative Selection of Water Treatment Process Scheme for Extension Project of Chengbei Water Treatment Plant in Huzhou City

2004年湖州市自来水公司采用了城乡一体化的集中供水方案,为此原城北水厂需再扩建 20×104 m3 /d。从预处理、混合方式、絮凝形式、沉淀形式、滤池和深度处理等 6个方面阐述整个净水工艺的比选,力求该工艺在满足原水水质变化和保证出水水质达标的前提下,尽可能降低运行成本。

Huzhou Water Supply Company adopted integrative and centralized water supply in urban and rural area in 2004, and so the former Chengbei Water Treatment Plant shall be expended with a capacity of 20×10~4 m^3/d. The comparative selection was made on the scheme of treatment process, including pretreatment, mixing, flocculation, sedimentation, filter, and advanced treatment, so as to reduce the operating cost as possible, while the process can satisfy the variation in raw water condition and ensure the quality of treated water.
