目的:了解目前再生水应用现状和水质特征。方法:通过对某地区80家再生水生产企业进行现场调查;采集再生水企业生产的再生水连续进行水质监测。结果:现场调查结果显示,再生水主要的应用领域为居民小区、学校、宾馆饭店和办公楼,主要用途为:冲厕和绿化、道路喷洒、景观、洗车、设备冷却及部分公共区域保洁等,生产再生水的水源为生活污水,氯消毒是再生水主要的消毒方式。水质特征分析结果,11项指示理化指标监测结果,除少数水质较差外,大部分结果可以达到用水标准限值;2项指示微生物指标显示,微生物是影响再生水水质主要问题,其原因与消毒效果有关。结论:再生水主要在居民小区、学校和其他公共场所使用,以冲厕和绿化为主,卫生学微生物指标不容乐观。
Objective: To understand the current status of reclaimed water applications and water quality characteristics. Methods: On-site investigation of 80 reclaimed water production enterprises in a certain area was carried out. The reclaimed water produced by reclaimed water enterprises was collected for continuous water quality monitoring. Results: The field survey showed that the main application areas of reclaimed water were residential areas, schools, hotels and office buildings. The main uses of the reclaimed water were: flushing and greening, road spraying, landscape, car washing, equipment cooling and cleaning in some public areas. Production Recycled water for domestic sewage, chlorine disinfection is the main disinfection of reclaimed water. The results of water quality analysis and 11 indicators of physical and chemical indicators monitoring results, with the exception of a small number of poor water quality, most of the results can reach the standard limits of water; 2 indicators of microbial indicators show that microorganisms are the main problems affecting the quality of reclaimed water, the reason and disinfection related. Conclusion: The reclaimed water is mainly used in residential quarters, schools and other public places, with flushing and greenery mainly. The indicators of hygiene microorganisms are not optimistic.
