摘要
城市污水的再生利用是解决城市缺水的有效途径之一.根据再生水的来源及性质,将灌溉绿地水质控制项目分为基本控制项目和选择控制项目两类.基本控制项目主要包括再生水灌溉绿地对植物生长和土壤、地下水、人身健康安全有影响的指标,共计13项;选择控制项目包括对环境有较长期影响或毒性较大的污染物指标,共计22项.根据国内外研究概况、室内水培试验和田间灌溉试验的结果,总结再生水灌溉绿地水质控制标准,对每项指标给出了最大限值.
Utilization of reclaimed water is one of the effective ways to solve the problem of lacking water in cities. According to the resource and characteristics of urban recycling water, water quality control indices should include basic control indices and selective control indices. Basic control indices are those related to the influence of urban recycling water used in greenland irrigation on the plant growth, soil, groundwater and human health as well as safety, up to 13 items. Selective control indices are t...
