The optimal occlusion method, called PVA - aluminate, has been developed by comparing several immobi-lization methods. By immobilizing the enriched nitrobacteria separately, the feasibility of applying microorganism immobilization technology to the denitrification of coking wastewater is studied. During the experiments, the activation process of the immobilization bacteria, the sensitivity to temperature and the adaptation to the coking wastewater have been investigated. The result shows that it is feasible for nitrobacteria immobilized by the method of PVA - aluminate to denitrify coking wastewater, and it is good for further research.
Key words: immobilization; nitrobacteria; coking wastewater; polyvinyl alcohol; aluminate
