活性污泥原位消化减量工艺的原理及应用

Principle and application of in-situ digestion reduction technology of activated sludge

本课题是关于活性污泥原位消化减量技术应用的研究。当前市场上现有生化处理技术无一例外需要排放剩余活性污泥,而当剩余活性污泥一旦产生就很难处理。本文的研究重点是消除活性污泥产生的条件,即在活性污泥产生前,对产生活性污泥的原水进行处理,使原水不具备产生剩余污泥的条件。该研究是基于羟基自由基的特性,以此特性在原水中提前施加影响代替后续处理剩余活性污泥的过程,从而大大地减少了剩余活性污泥处理难度,并且,这一系列的作用都是在生化池内完成,即原位消化过程。

This project is about the application of activated sludge in-situ digestion and reduction technology.The existing biochemical treatment technologies in the current market without exception need to discharge the residual sludge,and once the activated sludge is generated,it is difficult to treat.The focus of this study is to eliminate the conditions for the production of activated sludge,that is,before the production of activated sludge,the raw water that produces activated sludge is acted on,so that the raw water does not have the conditions for the production of residual sludge.The research is based on the characteristics of hydroxyl radicals produced,which is applied in the raw water in advance to replace the subsequent process of sludge treatment,thus greatly reducing the difficulty of activated sludge treatment.And,this a series of action is done in the biochemical pool,namely in-situ digestion process.
