摘　　要：针对城市污水处理厂产生大量的污泥,综述了臭氧化污泥减量技术的国外研究成果,介绍并讨论了臭氧化污泥减量的原理、污泥减量效率与臭氧剂量的关系、臭氧化污泥回流对污水处理运行效果及对污泥沉降脱水性能的影响,对臭氧化污泥减量技术进行经济评估,表明臭氧化污泥减量技术具有广泛的应用价值。Municipal wastewater treatment plant produces a lot of sludge. This paper summarized the abroad study results of ozonation sludge minimization technology, Introduction and discussion were made on the principle of ozonated sludge minimization, the efficiency of sludge minimization and the relationship between efficiency and ozone dosage, as well the effect of return sludge ozonated on wastewater treatment running and the sludge settling and dewatering characteristic. The economic estimation was also made on this technology. It＇s showed that sludge minimization technology exhibits extensive application foreground.
