Comprehensive Analysis of Application in Grey Water Treatment and Recycling Technology
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.
