Research Progress on the Functional Microorganisms in Enhanced Biological Phosphorus Removal(EBPR)Systems
摘要
Abstract
Phosphorus emission from human activities is one of the major causes of water eutrophication. The technology of enhanced biological phosphorus removal(EBPR)has been widely applied for removing phosphorus from wastewater due to its advantages of economy and sustainability. The key to the efficient and stable operation of EBPR system is that the microbial community in the system is reasonable and functional. For deeply understanding the mechanism of phosphorus removal and the efficient and stable operation of EBPR system,a large number of studies were conducted on the microbial community structure and main functional microorganisms in the system. In addition to polyphosphate-accumulating organisms(PAOs),the EBPR system also includes non-PAOs,mainly glycogen-accumulating organisms(GAOs) and some auxiliary bacteria. Nowadays,more and more types of functional polyphosphate-accumulating microorganisms were identified,and the most studied PAOs and GAOs were Accumulibacter and Defluviicoccus respectively. PAOs and GAOs compete or cooperate under different environmental conditions,but it is still controversial whether PAOs may exhibit the metabolic properties of GAOs under certain conditions. Besides the traditional factors such as carbon source,pH and temperature,the effects of exogenous pollutants,like antibiotics and heavy metals,on functional microorganisms in EBPR system also exist. The traditional separation methods,blue/white screening and the method of artificial construction of gene engineering bacteria have been applied for acquiring efficient PAOs. The development of modern molecular biologytechnology provides advanced and reliable technical means for the research of functional microorganisms in EBPR system,and the efficient removal of phosphorous by constructing high-performance polyphosphate-accumulating microorganisms will be an important trend in future increasing bio-removal phosphorus efficiency from actual wastewater.关键词
