Using the PFU method, the protozoan communities in a treatment system of Pb Zn mine tailing water were studied in situ , and the characteristics of protozoan community structures and their colonization were analyzed. In combination with physicochemical data of the water, the efficiency of the treatment system was monitored using protozoan community data. The results showed that the protozoan community in the system was mainly composed of zoomastigia and ciliates. The number of species and individual abundance, as well as diversity index ( d value) obviously increased with the increasing of the distance from sampling sites to pollutant outlet. The species number in protozoan communities was well negatively correlated with the pollutant concentrations in the water. The colonization of protozoan communities in different sampling sites showed the environmental differences. The results also showed that the cultivation of Typha latifolia made the suspended particles deposit down and had the protozoan communities restored to some extend.
