摘要
强化生物除磷(EBPR)是一种经济、高效、可持续的除磷工艺之一,然而聚糖菌(GAO)的过量生长将导致EBPR系统恶化甚至完全失效。介绍了GAO的厌氧/好氧代谢机制,重点总结了两种GAO(Competibacter和类Defluviicoccus vanus细菌)的生物学特性,分析了碳源、pH、温度等影响GAO生长的关键因素,并对今后的研究进行了展望。
Enhanced biological phosphorus removal （EBPR） is one of the most economical and sustainable process options for phosphate removal. However, deterioration or even complete failure of EBPR could happen because of the proliferation of glycogen-accumulating organisms （GAO）. The anaerobic and aerobic GAO metabolic mechanisms were reviewed, and especially the microbial characteristics of two groups of GAO （Competibacter and Defluviicoccus vanus related organisms） were introduced, and the key factors were analyzed, such as carbon source, pH and temperature, that affect the growth of GAO. Based on the review, some future research directions were suggested.
