回流臭氧化污泥对污水处理系统影响的研究进展

In? uences to the Parameters of Activated Sludge by Ozone Research Development

目前,大部分污水处理厂采用活性污泥处理技术,其弊端是产生大量的剩余污泥,而剩余污泥的处置已成为最主要的难题.因此,在其背景下提出了污泥减量技术,臭氧以其独特的强氧化性被应用到污泥减量技术中.笔者介绍了臭氧化污泥减量的机理;总结了近期臭氧化污泥在各处理系统中对硝化、反硝化及除磷方面的进展;提出了臭氧化污泥减量技术有待解决的问题。

Presently, the majority of sewage treatment plant uses the actived sludge processing technology, the actived sludge processing technology＇s malpractice produces the massive excess sludges, excess sludge handling into difficult problem, therefore the sludge reduction technology was proposed under its background, the ozone is applied by its unique strong oxidability in the sludge reduction technology. The article introduced the mechanism of ozonize sludge reduction as well as summarized the short-term ozonize sludge in some processing system to the nitration, the denitrification as well as eliminates the phosphorus direction the progress. Proposed the ozonize sludge decrement technology all remains unresolved question.
