摘　　要：灰水在生活污水中占有较大比重,且污染负荷和致病因子含量较低,因此,对灰水进行处理并实现资源化回用对于实现水资源持续供给,保障水资源安全具有重要意义。文章基于灰水的水质和水量特点,介绍了目前主流的灰水处理技术,对其作用原理、技术特点、应用条件进行了系统论述,并且综合对比了不同处理技术的优劣势。其中,生态处理法建设成本低,运维简单,具有一定的抗水质水量冲击能力,具有较好的推广应用价值。在此基础上,进一步总结了国内外再生水回用标准,分析灰水资源化回用的经济和生态效益,明确了处理灰水资源回用的可行性。最后,针对目前面临的问题和挑战,提出了未来的发展方向,即开发多种技术耦合、低成本的集成规模化灰水处理回用系统。Grey water occupies a large proportion of domestic wastewater,with low pollution load and less pathogenic factor concentration.Therefore,it is of great significance to treat grey water and realize resource reuse to ensure the sustainable supply of water resources and the security of water resources.Based on the quality and quantity characteristics of grey water,this paper introduces the current grey water treatment technology,and the removal mechanism,technical characteristics are discussed systematically.In addition,the advantages and disadvantages of different treatment technologies are also compared comprehensively.Among them,the ecological treatment method has advantages of low construction cost,convenient maintenance,and ability to resist water quality and quantity variation which has high value in popularization and application.On this basis,this paper further summarizes the domestic and foreign recycled water reuse standards,analyzes the economic and ecological benefits of grey water reuse,and clarifies the feasibility of treating grey water reuse.Finally,according to the current problems and challenges,the multi-technology coupling,low-cost integrated scale grey water treatment and reuse system are proposed as the future development direction.
