应用国家标准《水质—微型生物群落监测—ＰＦＵ法》对位于广东省韶关的凡口铅锌尾矿废水处理系统中的原生动物群落进行了研究．分析了在该处理系统中原生动物群落的结构和群集过程的特征，并结合水质的理化参数对该处理系统的效能进行了评价．结果表明：在该处理系统中，以动物性鞭毛虫和腐生性纤毛虫为原生动物群落的主要组成部分；随着采样点距排污口的距离延长，原生动物群落的种类数和密度明显增加；群落多样性指数也随之上升．通过对原生动物群落组成与污染物浓度的统计学处理，显示出群落的种类数与各污染物的浓度间存在着显著的负线性相关．各采样点ＰＦＵ原生动物群落群集过程也可以反映出各样点环境间的差异．各采样点数据间的差异说明由于该处理系统中香蒲植物的作用，使得废水中大量的颗粒性悬浮物得到沉降，重金属浓度也明显降低，从而促进了原生动物群落在一定程度上的恢复
The protozoan community located in the waste water treatment system of the fankou lead-zinc mine in Shaoguan of Guangdong Province was studied using the national standard “Water Quality - Microbial Community Monitoring - PFU Method”. The characteristics of protozoan community structure and clustering process in this treatment system were analyzed. The efficiency of this treatment system was evaluated in combination with the physical and chemical parameters of water quality. The results showed that: In the treatment system, animal flagellates and saprophytic ciliates are the main components of protozoan communities. With the distance of sampling points to the sewage outfall increasing, the number and density of protozoan communities increased significantly. The community diversity index also increased. Through the statistical analysis of the protozoan community composition and the pollutant concentration, it shows that there is a significant negative linear correlation between the species number of the community and the concentration of each pollutant. The PFU protozoan assemblage at each sampling point can also reflect the differences between the various point environments. Differences between the data at each sampling point indicate that due to the action of cattail plants in the treatment system, a large amount of particulate suspended matter in the wastewater is settled and the concentration of heavy metals is significantly reduced, thereby promoting the restoration of protozoan communities to some extent
