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 view of the water quality is seriously polluted by ammonia nitrogen and organic matter, biological nitrogen and nitrogen removal efficiency in winter under low temperature conditions, as well as urban and rural integrated water supply system of towns and villages at the end of the pipe network of water quality failed to achieve stability and other issues, carried out to improve water quality, improve water treatment process adaptability And efficiency, improve the distribution system from source to the leading integrated technology system research, the Jingganggang wetland (water), the Jing-Jinggang waterworks (water treatment), water supply area in Jingganggang water supply network system ( Pipe network) three organic combination, and a systematic demonstration to address the country’s most polluting river network water drinking water quality and safety, to achieve the demonstration area of 600,000 people leading water quality standards.
