Effect of controlling filamentous bulking sludge by Sequencing Batch Reactor Activated Sludge Process

Three groups of SBR reactors A, B and C with different aeration time were set up to culture the activated sludge which has already bulked. The results showed that settling performance in reactor A changed a little, but had been significantly improved. High-throughput sequencing significant inhibitory effect on growth Thothrix, longer was, more obvious inhibition was. When is than 6h, mode can effectively inhibit filamentous bulking, time, better effect.
