摘要
针对现行再生水水质标准、规范的执行情况进行了讨论,提出了再生水回用于工业循环冷却水时氨氮浓度控制在5mg/L以下,应根据现实情况近期适当降低某些城市河道的水体功能,在《城市污水再生利用城市杂用水水质》中列入部分能够全面反映水质安全的关键性指标,城市公共再生水尽量采用统一供水水质等一系列建议。
In this paper the implementation of five quality standards and design codes of reclaimed water is discussed and some suggestions are given. The concentration of NH3-N should be lower than 5 mg/L when the reclaimed water is used for industrial cooling water. To be convenient for scenic environment use, it is better to lower the water body function of some city rivers temporarily to a properly degree according to realistic circumstances. Some critical parameters which indicate the safety of reclaimed water are better to be included in the water quality standard. The urban public reclaimed water system is better to use a uniform water quality.
