碳源对聚磷菌厌氧释磷影响的研究进展

The Research Progress on the Effect of Carbon Sources for the Growth of Bacteria Anaerobic Releasing Phosphorus

论述了碳源种类和浓度对厌氧释磷过程的影响。由挥发性脂肪酸(Volatile fatty acids)诱发的磷酸盐释放一般都优于其它碳源,明确以乙酸为基质的相关生化机理模型从生物代谢和还原力供给方式方面的差异,VFAs以外的基质(葡萄糖,淀粉等)是否能释磷以及释磷作用机理还有待研究,聚糖菌的存在会抑制聚磷菌的作用。当有机负荷率超过某一临界值后,其不再是厌氧释磷的限制性因素。针对碳源对厌氧释磷影响因素的最新进展进行了分析和归纳。尽管很多研究者在该领域进行了研究并取得了一定成果,但依然存在很多争议和无法解答的问题,还需要进行进一步的研究。

Discusses the effect of carbon source type and concentration for anaerobic phosphorus releasing process.Phosphate releasing by VFAs（Volatile fatty acids） is general superior.Clear the biochemical mechanism and the difference of biological metabolism,power supplying model for acetic acid as a substrate.With out VFAs（glucose,starch,etc.） whether it is able to release phosphorus and phosphorus releasing mechanism has yet to be studies.With the presence of GAOs will restrain phosphorus releasinghen organic load reach the critical,which is no longer the restrictive factor.Although many researchers study in this field and recive some achievements,many disputes still exist and many problems cannot solve,which needs further research.
