城市景观河流水质污染防治进展研究

Review of Pollution Control in Urban Landscape River

城市河流在维持城市发展中具有重要作用。城市河流的主要问题是由水质污染转变的生态退化或破坏,城市景观河流水质污染防治主要有物理、化学法、生物修复以及生态恢复法。针对不同的城市河流以及污染情况,需要用不同的污染防治措施,通过分析不同污染防治措施的原理及其应用特点,得出生物修复以及河水生态恢复效果明显且经济可行。并明确了目前城市河流污染防治的关键在于处理技术的创新及城市河流理念现代化。

Urban river plays an important role in maintaining the development of a city. Recently,the urban river suffered serious problems from water quality pollution to ecosystem degradation. The pollution controlling methods are generally classified as physical,chemical,bioremediation and ecological recovery method,which could be applied to improving the water quality of urban rivers under different pollution situations. This study mainly analyzed the theory and applying characteristic of different controlling methods,and clarified that the key point of pollution controlling is processing technology innovation and the concept of urban river modernization.
