【 摘 要 】

Because of the large content of organic matter as well as nitrogen, the competition between phosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs) was serious in wastewater. This phenomenon led to biological phosphate removal in a SBBR with micro-bubble technology was not quite effective. Meanwhile, it can be concluded that the high dissolved oxygen (DO), ammonia nitrogen(NH4+), sludge solubilization affect the biological phosphate removal seriously. This paper was aimed to provide some information's to improve the phosphate removal in the next step.
