再生水回用于社区景观水体的富营养化风险与成本分析

摘要

以深圳某社区内人工快渗处理装置与人工景观水体系统为例,根据再生水换水控制实验和富营养化模型模拟结果,建立再生水水质、换水周期与景观水体富营养化风险的关系 ;结合再生水处理成本分析,建立该系统运行费用、占地面积与水体富营养化风险的关系曲线.该方法可为社区景观水体设计与维护中权衡再生水处理成本与景观水体富营养化风险的矛盾提供科学依据.%An artificial rapid infiltration treatment and landscape water system in a community in Shenzhen was studied. The relationships between reclaimed water quality, the water exchange cycle, and eutrophication were established based on the results of a water exchange experiment and eutrophication simulation. The relationships between treatment cost, occupied area of treatment facilities, and eutrophication risk of the landscape water were obtained through cost analysis. The results indicate that the method can provide a scientific basis for balancing the contradiction between the cost of reclaimed water and the eutrophication risk of landscape water in design and maintenance of the community landscape water body.
