污泥水解酸化的影响因素及研究进展

The Influence Factors and Research Progress in Hydrolysis and Acidification of Sludge

水解酸化处理方法是一种介于好氧和厌氧处理法之间的方法,与其它工艺组合可以降低处理成本提高处理效率。本文综述国内外应用于污泥处理中水解酸化的影响因素,主要阐述了温度、HRT、SRT、ORP和p H等对污泥水解酸化的影响。为水解酸化与化学淋滤法脱除污泥中重金属的联用提供了方向及理论依据。

Hydrolysis acidification process is a method between aerobic and anaerobic treatment, what’s more, it can be reduce the processing cost and improve processing efficiency by Combined with other process. This paper discussed the influence factors in hydrolysis and acidification of sludge treatment both in domestic and foreign. the temperature, HRT, SRT, ORP and p H effects on sludge hydrolysis acidification were mainly reviewed. Provides direction and theoretical basis of leaching heavy metals in sewage sludge by the method combined Hydrolysis/Acidification and chemical leaching method.
