城市河流水污染治理和修复技术:以新凤河流域为例

Treatment and Remediation Technologies for Polluted Urban River:A Case Study of Xinfeng River Basin

随着我国工业化、城市化进程的快速发展,城市河流污染已成为严重的环境问题。本文首先基于对新凤河流域的分析,阐明新凤河流域的水体污染现状以及污染水体治理和修复重要性和必要性。其次,提出污染水体修复策略的十六字方针为"预防为主,生态为要,全面介入,因地制宜"。最后,从物理、化学和生物方法阐述新凤河流域污染水体的治理及修复技术,特别是生态修复由于具有独特的优势成为新凤河流域污染水体治理和修复技术中最有应用前景的方案。

With rapid industrialization and urbanization, urban rivers＇ pollution has become a serious environmental problem in China. In this paper, the current situation of polluted Xinfeng River and its fuodamentality and necessity for treatment and remediation were stated firstly based on the analysis of Xinfeng River Basin. In the second part, the strategy of remediation for polluted Xinfeng River was put forward, taking into account of＂Prevention First, Ecology Key, Intervention Comprehensive, Local Conditions＂. At last, the treatment and remediation technologies for Xinfeng River included physical method, chemical method, and biological method, specially the ecological remediation became the most potential method to solve the pollution from Xinfeng River due to its unique advantages.
