Abstract: Microalgae was introduced into MBR to construct the microalgae-based membrane bioreactor system (A-MBR).The effects of the system on the removal of organic pollutants,N and P in wastewater and the influence of microalgae on membrane fouling were investigated.The results shown that the removal efficiency of COD in A-MBR system was more than 90%,and the COD content in effluent was lower than 50 mg/L,which conformed the first-class A permitted criteria.Compared with the traditional membrane bioreactor system (S-MBR),the A-MBR system had an average removal rate of total phosphorus of 10.1% and a higher removal rate of NH+4-N.At the same time,the average increase rate of membrane pressure difference (TMP) in A-MBR system decreased by 19.4% compared with S-MBR system,indicating that microalgae can effectively alleviate membrane fouling of MBR system.
