Sequencing batch type intermittent operation mode is used to investigate the effect of temperature, microbial content and activated sludge system on the activation characteristics of gel-embedded nitrobacteria carriers. The changes of water quality in the gel-embedded nitrobacteria carriers' initial activation and the activation performance of gel-embedded nitrobacteria carriers in the expanding scale are studied. The results indicate that the mass concentrations of ammonia nitrogen and nitrate nitrogen are rising in the initial activation because of different compositions of gel-embedded carriers. The appropriate temperature is beneficial to gel-embedded nitrobacteria carriers' activation. Under the premise of not affecting the activation performance of gel-embedded nitrobacteria carriers, the microbial content can be reduced to decrease the production cost. Activated sludge will prolong the activation time of gel-embedded nitrobacteria carriers. But activation performance under conditions of continuous operation is superior to intermittent operation mode. Source
