摘要
针对水源水质受氨氮和有机物污染严重,冬季低温条件下生物除氨氮效率下降,以及城乡统筹供水系统乡镇末端管网的水质未能稳定达标等问题,开展了水源水质改善、提高水处理工艺适应性和高效性、完善输配水系统等从源头到龙头的集成技术体系研究,将贯泾港湿地(水源)、贯泾港水厂(水处理)、贯泾港水厂供水区管网系统(管网)三者有机地结合,并进行系统的示范,解决了全国污染最严重的河网水源水的饮用水水质安全,实现了示范区60万人口的龙头水水质达标。
In Jiaxing plain river network, the source water has been severely polluted by ammonia and organic pollutants, and the removal efficiency of ammonia nitrogen decreases under low temperatures in winter, in addition, in urban and rural integrated water supply system the water quality at rural deadends fails to meet the Standards for Drinking Water Quality （ GB 5749 - 2006）. Research was carried out on integrated technologies to improve source water quality, to enhance water treatment process adaptability and effidiency, and to perfect water quality in water distribution system. Three demonstration projects were developed at the source water wetland, the water treatment plant, and the water distribution systems at Guanjinggang. The results demonstrated that the drinking water quality of pipe network in demonstra- tion area had reached GB 5749 - 2006. Therefore, the drinking water safety was ensured in the river network region where water resources were seriously polluted.
