摘　　要：浙江某自来水厂总规模为10万m^(3)/d,分3期建设,其中一、二期规模6万m^(3)/d,三期新增4万m^(3)/d供水量。净水工艺采用管道混凝、折板反应、平流式沉淀、普通快滤池过滤、常规消毒工艺。水厂出水水质符合国家现行GB5749—2006《生活饮用水卫生标准》,本次改造要求其满足《浙江省城市供水现代化水厂评价标准实施细则(2008版)》。针对厂区可用土地少、改造时间短、尽量不影响水厂运行的实际,本工程对现状普通快滤池改造为气水反冲滤池。改造完成后,净水厂运行稳定,出水水质达到设计标准。A waterworks in Zhejiang province has a total scale of 100,000 m^(3)/d, which is divided into three phases, of which the scale of the first and second phases is 60,000 m^(3)/d, and the water supply of the third phase is increased by 40,000 m^(3)/d.The water purification process adopts the conventional process of pipeline coagulation, folding plate reaction, horizontal flow precipitation, ordinary fast filter and disinfection. The effluent quality of the water plant is in line with the current national Standards for drinking water quality(GB5749—2006), and the reform requires it to meet the Implementation Rules of evaluation Standards for Modern Urban Water Supply Water Plants of Zhejiang Province(2008 edition). In view of the char acteristics of les s available land, short transformation time and as far as possible not affecting the operation of the water plant, this project transformed the current common fast filter into gas-water backwash filter. After the renovation, the water purification plant runs stably and the effluent quality reaches the design standard.
