利用天然河浜及沟塘湿地深度净化污水处理厂尾水的研究

随着我国经济社会的不断发展,对水环境质量改善的需求也愈来愈迫切,以脱氮除磷为主要目标的污水处理厂深度处理和升级改造势在必行。推广应用污水处理厂除磷脱氮工艺的最大障碍是经济成本问题。因此,在条件适宜地区采用低成本的自然生态净化措施来取得除磷脱氮效果仍是合适的选择之一。该文研究提出了利用天然沟渠湿地进行污水处理厂出水深度净化与景观利用的技术集成方案,以期为类似工程设计和运行管理提供参考。

Study on Tail Water Purification by Combined Natural River Stream and Ditch-pond Wetland from Municipal Sewage Treatment Plant

With increasing development of our economic society,the requirement of improvement of water environ-mental quality is becoming more and more urgent. The deeply treatment and upgrading of water treatment plant which is mainly targeted with removing of nitrogen and phosphorus must be enforced. Therefore,in some areas with suitable environment,it is still a very appropriate choice to take low-cost deeply ecology cleaning measures for re-moving of nitrogen and phosphorus. In this paper,it is proposed to apply the combined technology to clean deeply the water by natural river stream and ditch-pond wetland,so as to provide reference for similar engineering design and operating management.
