剩余污泥酸性发酵释磷影响因素研究进展.

Focusing on the form and release characteristics of phosphorus in the surplus sludge, this paper expounds the influence of biological phosphorus removal process and chemical synergistic phosphorus removal method on the difference of phosphorus form, analyzes the phosphorus release and transformation mechanism in the two key stages of hydrolysis and acidification of the surplus sludge, and clarifies that the factors such as hydrolase, acid producing bacteria, temperature and additional carbon source mainly improve the acid fermentation efficiency by affecting the enzyme activity, microbial metabolic activity and growth rate, thereby improving the release rate and conversion efficiency of phosphorus. By summing up, the paper points out the existing disputes in the research and looks forward to the future development direction. [ABSTRACT FROM AUTHOR]
