浅析再生水工业回用的水质保障问题

摘要

工业行业应当成为城市再生水的主要用水户.由于工业用水的特殊性,对于再生水的水质要求与农业、市政、环境用水有一定的差异.通过对再生水工业回用水质标准、实际用水中受关注的水质参数分析,论述了再生水水质安全保障的要点.结合国内外的经验,对再生水生产的主要工艺及对污染物的去除效率进行了分类和范例分析.%Industries should be the main users of reclaimed water in urban area. Due to the special characteristics of industrial water, the requirement on the quality of the reclaimed water for industry use is different from that for other sectors such as agricultural, municipal and environmental use. Through the analysis on the water quality standard of water reuse for industries and the main parameters of water quality in practical production, the related issues on the safety guard of the reclaimed water quality were discussed. Following the experiences at home and abroad, the main processes for reclaimed water production from domestic wastewater were categorized and their characteristics of pollutant removal were discussed.
