Highlights

The nutrient removal was higeher with short-chain fatty acids as carbon source.

Candidatus Accumulibacter was more easily enriched in A2N-MBR process.

Short-chain fatty acids were beneficial to the growth of PAOs.

Abstract

Effect of different carbon sources on purification performance and change of microbial community structure in a novel A2N-MBR process were investigated. The results showed that when fed with acetate, propionate or acetate and propionate mixed (1:1) as carbon sources, the effluent COD, NH4+-N, TN and TP were lower than 30, 5, 15 and 0.5 mg·L-1, respectively. However, taken glucose as carbon source, the TP concentration of effluent reached 2.6 mg·L-1. Process analysis found that the amount of anaerobic phosphorus release would be the key factor to determine the above effectiveness. The acetate was beneficial to the growth ofCandidatus Accumulibacter associated with biological phosphorus removal, which was the main cause of high efficiency phosphorus removal in this system. In addition, it could eliminate theCandidatus Competibacter associated with glycogen-accumulating organisms and guarantee high efficiency phosphorus uptake of phosphorus accumulating organisms in the system with acetate as carbon source.
