摘　　要：为了促进城镇生活污水处理厂污泥浓缩处理技术的研究,深入分析了污泥浓缩技术的发展,着重研究了重力浓缩、机械浓缩和气浮浓缩。结果表明,城镇生活污水处理厂污泥减量化日益受到重视,污泥浓缩是污泥减量最重要的手段;重力浓缩仍是城镇污水处理厂污泥浓缩的主要手段,但由于环境观感较差、污泥释磷等问题,呈现被机械浓缩与气浮浓缩逐渐取代的趋势;气浮浓缩中的涡凹浓缩技术具有投资费用少、占地面积小等优点,成为目前的研究重点,是未来城镇污泥浓缩技术发展的重要方向。In order to promote the research of sludge thickening technology in municipal sewage treatment plant, the development of gravity thickening, mechanical thickening and flotation thickening of sludge thickening technology was analyzed. It was concluded that sludge reduction of municipal wastewater treatment plant had attracted more and more attention and sludge thickening was the most important way of sludge reduction. Gravity thickening was still the main means of sludge thickening in municipal wastewater treatment plant, but it had showed a trend of being replaced by mechanical thickening and flotation thickening gradually because of the poor environmental perception and phosphorus release issues. Cavitation air flotation technology had become a focus of research for the advantages of low investment cost and small land occupy, it is the important developing trend of municipal sludge thickening technology in the future.
