城市再生水景观生态利用过程中的磷污染控制

Phosphorus pollution controlling of reclaimed water utilization in urban landscape ecological construction process

随着我国经济发展速度的提升以及人们意识的上升,城市的景观生态建设成为了必须,导致经济发达地区用水需求与水资源短缺的矛盾益发突出。再生水的利用可有效的缓解水环境压力,但同时也存在富营养化隐患。本文介绍了当前常用的几种生态工程技术,及其优缺点,以期为我国城市再生水回用提供有意义的借鉴。

With the increasing of economic development and the rising of citizens awareness,the urban landscape ecological construction becomes necessary,resulting the serious contradiction of water demand in developed areas with water shortage.The utilization of reclaimed water can effectively alleviate the pressure of water environment,but it still has eutrophication risk.Several current ecological engineering technologies and their advantages and disadvantages are introduced in this article,aiming to provide meaningful reference of urban reclaimed water.
