【摘要】 将城市污水处理厂出水经过处理后作为河道景观补给水的做法正在多个城市应用,本文在假设没有外源性污染的前提下,对宁波市某污水处理厂深度处理后的中水回灌于城市内河可行性进行了实验室模拟,结果显示达到实验水质指标的中水,以每天置换1/30的流量引入受污染城市内河,在解决河道水资源紧缺问题的同时,不会对原有河道水质带来大的危害.文章还针对实际的应用提出了一些建议。更多还原

【Abstract】 It has been applied in many cities that the effluent of urban sewage treatment plant,through advanced treatment,can be used as water supply of river channel.Assuming without external pollution,simulation experiment on the middle-water from some sewage treatment plant recharging urban river was conducted,and the result demonstrates that the middle-water reaching experimental standard is beneficial to settling shortage of urban river resources.If recharged in the polluted urban river as 1/30 everyday,the middle water will not do harm to original water quality.In addition,some proposals for practicality were also put forward.更多还原
