摘　　要：对微污染水源水质特点的分析表明,微污染水源水的污染指标以高锰酸盐指数和氨氮为主,具有高锰酸盐指数较高、氨氮浓度较高、嗅和味明显等特点,通常采取强化常规处理、增加预处理单元、增加深度处理单元、增加膜技术等手段,使出水水质达到饮用水水质标准。介绍了以常规工艺为基础的各种水质处理技术及其适用范围,并推荐预处理/常规工艺、常规工艺/深度处理工艺、预处理/常规处理/深度处理工艺、预处理/常规处理/深度处理/膜技术等方案,可作为以高锰酸盐指数和氨氮污染为主的微污染水处理工艺。各水厂可根据原水的污染程度和所在地区的经济能力,选择适宜的处理工艺。The characteristics of micro-polluted source water quality were analyzed. The results showed that the main pollution indicators were potassium permanganate index and ammonia nitrogen, and this type of source water was characterized by high potassium permanganate index, high concentration of ammonia nitrogen, distinct smell and odor. The enhanced conventional process, pretreatment process, advanced treatment process and membrane technology were usually used to ensure the treated water quali- ty to meet the drinking water quality standard. Different available technologies and their fields of applica- tion were introduced based on conventional processes. Pretreatment plus conventional process, conven- tional plus advanced treatment process, pretreatment plus conventional process plus advanced process, pretreatment plus conventional process plus advanced treatment process plus membrane technology were recommended to be used as micro-polluted source water treatment process. The suitable process should be selected according to the source water quality characteristics and the regional economic capacity.
