北江某自来水厂净水工艺方案比选

Comparative selection of water treatment process schemefor a water treatment plant in Beijiang

随着城市的发展、经济水平的提高,对水质和供水安全提出了更高的要求。立足于原水水质分析,以普遍实现直饮、与城市供水国际水平接轨的设计角度,从工艺框架选择、传统砂滤与现代超滤进行比较、深度处理与预处理等方面阐述净水工艺的比选,提出了生物预处理/常规处理工艺/臭氧活性炭/超滤膜处理工艺。

With the development of the city and the improvement of economic level,higher requirements are put forward for water quality and water supply security.Based on the analysis of raw water quality,in order to realize direct drinking and in line with the international level of urban water supply,the comparative selection was made on the scheme of treatment process,including the treatment process framework selection,comparison of traditional sand filtering with modern ultrafiltration,pretreatment and advanced treatment.The combined process of biological pretreatment,conventional treatment,ozone/activated carbon and ultrafiltration treatment was proposed.
