摘要

安全回用水通常是指提供质量符合保障人体健康和水生生态标准的再生水。关于这一点,人们常常过分强调通过工程过程去除有害物质的技术魔力,而忽略了利用大自然的力量为安全控制提供额外的障碍。基于对水循环保障水质功能的认识,以及水回用是通过水循环进行的这一事实,作者提出了创建准自然水循环进行水回用的观点。现有数据表明,在准自然条件下露天储存再生水对新出现的污染物去除和相关生物毒性的降低效果显著。土壤颗粒的吸附、阳光诱导的光解作用和水生生物的净化作用被认为是准自然方式有效改善水质的主要作用。因此,通过准自然水循环的安全水回用可以成为根据用水目的进行系统设计的可取策略。

Safe water reuse through a quasi-natural water cycle
Safe water reuse usually means the provision of reclaimed water with its quality meeting the criteria for safeguarding human health and aquatic ecology. Regarding this, people often overstress the technological magic in terms of hazardous substances removal by engineered processes while ignoring the utilization of nature's power to provide an additional barrier for safety control. Based on an understanding of the function of the hydrological cycle to secure water quality and the fact that water reuse is through a water loop, the author presented his viewpoint on creating a quasi-natural water cycle for water reuse. Existing data showed the remarkable effects of emerging pollutants removal and associated reduction of biotoxicities from the reclaimed water during open-storage under a quasi-natural condition. Adsorption by soil particles, sunlight-induced photolysis and purification by aquatic life were thought to be the major actions contributing to effective water quality improvement in a quasi-natural manner. Safe water reuse through a quasi-natural water cycle can thus be a recommendable strategy for system design in accordance with the purposes of water use.
