The diffusion behavior,mechanical performance,activation and biological property of gel-embedded nitrobacteria carrier LQ-1 were measured, and its application in the treatment of urban sewage was studied by pilot experiment. The results show that the interpenetrating holing-through structure (about 5μm) is formed in the immobilized nitrifying bacteria carrier. When the compression rate is 85%,the compressive stress reaches 0.49 MPa. More than 95% of the diffusion process can be completed in 10 minutes. The optimal activation time of immobilized carrier is 13d under suitable temperature, and a higher biological activity can be achieved after activation at low temperature (<10˚C). Reducing the microbial content, the property of carrier above can still be obtained. The activation time of gel-embedded nitrobacteria carrier in pilot experiment is no more than 11d, and the system can achieve qualified operation at low sludge concentration. The effluent concentration of NH3-N is below 1 mg/L with removal rate more than 99% by using the activated carrier under conditions as temperature 13~15˚C, influent loading 72.5 m 3 /d (1.45 times of design value), adding ratio of carrier 12%, Do about 5 mg/L, which reveal that carrier is conducive to the upgrading and reconstruction of municipal wastewater treatment plant.
