摘要
城市污水的再生利用对缓解淡水资源短缺具有十分重要的意义,景观环境、娱乐水体需水量相对较大,对水质的要求也不尽相同,再生水作为景观环境和娱乐用水的补充水源成为污水再生利用的重要发展方向。从景观环境和娱乐水体的功能出发,通过分析再生水中残留的化学污染物和病原微生物对生态环境和人体健康可能造成的危害,建议采用卫生学指标、毒理学指标、营养盐指标、感官性指标、综合性指标等五类指标评价景观环境和娱乐用再生水的水质。
Reclamation and reuse of municipal wastewater is one of important ways for relieving the shortage crisis of freshwater resource, especially, due to the relatively large volume demands and different requirement for water quality, the scenic and recreational water bodies are main applications of reclaimed water. Considering the primary function of scenic and recreational water, the potential hazards of residual chemicals and pathogens in reclaimed water to ecosystem and human health are analyzed, and an index framework including hygienic, toxicological, trophic, sensory and integrated indices is proposed to evaluate the safety of reclaimed water quality.
