四川某小区人工湿地中水回用技术

中水回用是提高生活用水重复利用率的主要形式。提高水的重复利用率,是实现城市污水资源化是解决水资源短缺的根本途径。人工湿地既具有景观价值,又有污水处理功能。可以为市政绿化、农田灌溉景观提供水资源。经人工湿地处理的中水水质,出水水质符合我国的城市杂用水水质标准(GB/T18920-2002)、景观环境用水水质标准(GB/T18920-2002)和农田灌溉水质标准(GB5084-2005)。

Technology of Reclaimed Water Reuse in Constructed Wetlands for the Wastewater Treatment in Residential Quarters of Sichuan Province

Reclaimed water reuse is the main form to raise the recycle rate of domestic water. Raising the water recycle rate is the fundamental way to realize urban wastewater resource utilization and to solve the shortage of water resources. Constructed wetlands with both landscape value and the sewage treatment function could provide water for farmland irrigation and municipal greening landscape. By constructed wetland treatment, the effluent water quality conforms to China miscellaneous urban water quality standard （GB/T18920 -2002）, landscape and environmental water quality standard （GB/T18920 -2002） and farmland irrigation water quality standard （ GB5084 - 2005 ）.
