再生水在城市绿地中的应用

Application of Reclaimed Water in Urban Green Space

近年来城市绿地水资源供需矛盾日益突显,而再生水成本低且环保,将再生水应用于城市绿地灌溉和景观环境用水,有助于改善水资源短缺问题,实现生态可持续良性循环。通过对再生水应用于城市绿地景观领域的技术规范、重点关注指标、水质控制项目及限值的分析,表明再生水应用于绿地灌溉和景观环境用水是可行的,且短期内使用再生水对植物生长影响较小。

In recent years,the contradiction between supply and demand of water resources in urban green space is increasingly prominent.The cost of reclaimed water is low and environmental protection is achieved.The reclaimed water applied in urban green space irrigation and landscape environment is conducive to the improvement of water resources shortage and the realization of ecological sustainable virtuous cycle.Through the comparison and analysis of the technical specifications,key attention indexes,water quality control indexes and limits in the field of green space landscape of reclaimed water application,the results show that reclaimed water appliedingreen space irrigation and landscape is entirely feasible,andthe effect of using reclaimed water on plant growth is low in short term.
