人工曝气复氧整治污染河流

Renovation of Polluted River Water by Artificial Reaeration

向受到严重有机污染的河流充入溶解氧可以有效消除水体的黑臭,改善水质和恢复生态平衡。文章总结了纯氧增氧系统、鼓风机———微孔布气管曝气系统、叶轮吸气推流式曝气器和水下射流曝气设备等多种使用于河道人工曝气复氧的技术;并列举大量国内外的相关工程实例说明这些技术在实践中的有效性。

Oxygen restoration is one of the effective measures to clean foul water,improve water quality and restore the eco-balance.Several types of the technologies of artificial reaeration,such as pure oxygen aeration,etc.are discussed together with many examples both home and abroad to confirm the effectiveness of the technologies.
