摘　　要：微生物在活性污泥污水处理系统中具有至关重要的作用,活性污泥内微生物种群的组成决定了系统污染物的去除性能。本文针对污水生物脱氮除磷系统中微生物的种群优化进行了概述,主要介绍了AOB和NOB、PAOs和DPAOs以及GAOs和PAOs的相互关系,并分析了其种群优化的调控途径。Microorganisms play an important role in activated sludge wastewater systems,as the composition of microbiological community determines the pollutant removal performance.This paper reviews the sludge population optimization stated in the system of biological removal of nitrogen and phosphorus,and mainly introduces the correlation between AOB and NOB,PAOs and DPAOs,as well as GAOs and PAOs.Meanwhile the control approach of microbiological community is analyzed.
