The Research of Fluorescence In Situ Hybridization Approach Applied in Denitrification Bacteria in Metal Membrane Bioreactor

To research the composition and proportion of the denitrying bacterium in denitrification tank and increase the nitrogen removals rate. With the purpose of explore the curve between the amount of different denitrying bacterium and the quality of water treating, then find out the optimum of the species of nitrogen removal bacteria and the amount of the specific type of microorganism in the denitrification tank of metal membrane bioreactor at the optimized conditions of the water treating effects. The fluorescence in situ hybridization (FISH) approach is applied in this research, to set a preliminary study on the space-time character of denitrification bacteria population structure in denitrifical tank.
