江苏省城市再生水利用模式研究
|
摘要
江苏省水质型和水量型缺水并存,水生态文明建设和实行最严格水资源管理制度均对再生水的利用提出了较高要求。针对江苏实际情况,研究提出江苏在再生水利用推广中应以城镇污水处理厂达标尾水为重点,选择与水功能区和主要用户水质要求相匹配的再生处理工艺,采用"点到点"模式、"树状结构"模式或循环利用模式,分别应用于环境生态补(换)水、工业冷却水和城市杂用水。工业园区(集中区)对污废水实行集中处理后回用,鼓励按照不同水质要求进行不同深度处理、分质供应、循环利用。
Water quality limitation and water quantity shortages coexist in Jiangsu Province,and water ecological civilization construction and the strictest water resources management system impose higher requirements on the use of reclaimed water. Based on the practical situation of Jiangsu Province,the key of the reclaimed water use should be to ensure that the effluent from urban sewage treatment plants meets the standards. The treatment process that matches with water quality requirements of water function areas and main consumers should be selected. The point to point mode,tree-shaped structure mode or recycle mode are applied to environmental ecology water,industrial cooling water and miscellaneous water respectively. Wastewater from industrial parks should be reused after centralized treatment,and the principles are different advanced treatments according to different water quality requirements,different quality supply and recycling.
