黑臭河涌的修复方法及应用研究

Study on the Repaired Method of Black-Odor River and Its Application

随着工业化的快速发展、城市化进程的加快和人民生活水平的提高,污染物的排放量大大增加,造成了城市河涌的严重污染,使原本担负着排洪、泄洪、景观等多种功能的河涌出现黑臭现象,河涌水体原有的功能衰退甚至丧失。为了提高居民的生活水平,还给市民一个舒适、优美、富有情趣的生活环境,采取必要的措施对黑臭河涌进行修复势在必行。本文阐述了近几年国内外修复黑臭河涌的方法,总结并分析了该方法的特点及在我国的实例应用中产生的效果,寻求以生态文明建设为理念的修复黑臭河涌的方法。河涌修复是个综合性、系统性工程,单纯地依靠一种技术很难达到理想的效果,只有多管齐下,把几种技术组合起来方能达到预期的效果。

With the acceleration of the rapid development of industrialization, the improvement of urbanization and people＇s living standards, the emissions of pollutant have a large increase. The river has been pol- luted because of the large number of pollutants. In order to improve the quality of residential living and give people a comfortable, beautiful and interesting environment, seeking more effective technologies and measures to control river pollution is imperative. The methods at home and abroad in recent years which are about the restoration of black-odor river are introduced, and the characteristics of the me- thods and the effects of the instances in our country are summarized and analyzed to find a way to repair the black-odor river on the basis of the construction of ecological civilization. The restoration about the black-odor river is a comprehensive and systematic project. Relying on a technology only is difficult to achieve the ideal effect. In order to achieve the desired effect, a combination of the several kinds of technology is necessary.
