河流湖泊水体生物-生态修复技术述评

Comments on biologic-ecological rehabilitation techniques for rivers and lakes

从脱氮除磷及去除藻类两方面介绍了国内外生物生态修复技术,分析了水体生物生态修复技术的优缺点.分析表明:与磷资源回收利用相结合的脱氮除磷技术,具有工程造价低、耗能少、处理效果好且能实现资源回收利用等特点;超声波除藻技术及生物除藻技术,能有效地去除藻类且不会产生二次污染.

A review was made of the biologic-ecologic rehabilitation techniques at home and abroad from the aspects of nitrogen and phosphor removal and algae removal. Analysis shows that the nitrogen and phosphor removal technique, combined with the phosphor resource recovery and utilization, has the characteristics of low cost, low energy consumption, and good effect of treatment, and can realize the recovery and utilization of resources, and that the ultrasonic and biologic algae removal techniques can effectively remove algae without resulting in secondary pollution.
