%X In view of the high content of suspended matters in the Yellow River, the effect of particulates on nitrification has been studied under laboratory conditions. The results indicated that particulates exert significant effect on the nitrification processes, and the nitrification rate increased with the increase of particulate concentration. The mechanisms were elucidated. First, ammonium nitrogen can be absorbed on the particulates. Second, the particulates produce effect on the growth of ammonifying bacteria, nitrosobacteria and nitrobacteria. Third, the bacteria growth in liquid phase was different from that in solid phase.
