该文分析评价了目前国内外城市水体水质维护的各种技术方法,并结合某市河道水质现状及处理目标,确定采用加药气浮技术对城市河道水质进行维护。实践表明,采用该方法处理富含藻类的富营养化水体,可有效地去除藻类,降低水体中的N、P含量,并可使原V类或劣V类的地表水体达到IV类标准,满足景观娱乐用水的功能要求。

This article analyzes and evaluates various kinds of technologies for current water quality maintenance of urban waters at home and abroad. And combined with the present situation and treatment objective of water quality of an urban river, the dosing floatation technology is determined to use for the maintenance of the water quality of urban rivers. The practices show that this method used for treating the eutrophication rich in algae can efficiently remove the algae, reduce the N and P contented in the waters, and can make the surface water of the original Class V or bad Class V reach the standard Class IV, and satisfy the functional requirements of the water of landscape and entertainment.
