再生水是城市的第二水源。城市污水再生景观利用是提高水资源综合利用率,减轻水体污染的有效途径之一。再生水景观回用既能减少水环境污染,又可以缓解水资源紧缺的矛盾,是贯彻可持续发展的重要措施。污水的再生利用和资源化具有可观的社会效益,环境效益和经济效益,已经成为大多数城市景观水体的必选。而国内外学者对如何有效的修复再生水体富营养化问题做了很多研究,笔者总结了国内外关于再生水体富营养化的机理,化学修复、物理修复、生物修复及新型修复方法
Reclaimed water is the city’s second water source. The utilization of urban sewage regeneration landscape is one of the effective ways to improve the comprehensive utilization of water resources and reduce water pollution. The reuse of reclaimed water landscape can not only reduce the pollution of water environment, but also relieve the contradiction of water scarcity, which is an important measure to carry out sustainable development. Recycling and reuse of wastewater has considerable social, environmental and economic benefits and has become a must for most urban landscapes. However, scholars at home and abroad have done a lot of researches on how to effectively repair the eutrophication of reclaimed water. The author summarizes the mechanisms of eutrophication, chemical repair, physical repair,
