| 摘 要： | 系统研究了丝状菌膨胀与非丝状菌膨胀2种典型污泥状态下原生动物的群落结构特征及其演变规律。伴随丝状菌的大量增殖，原生动物总量相应减少，匍匐型纤毛虫及有壳类肉足虫数量迅速上升，占据明显的优势地位，典型原生动物为斜管虫（Chilodonella sp.）、小轮毛虫（Trochilia minuta）以及匣壳虫（Centropyxis sp.）；非丝状菌污泥膨胀对原生动物总量及种群结构影响较小，伴随粘性菌胶团的大量出现，各功能类群的比例变化较小，但原生动物总量持续增加，其中菌食性纤毛虫呈线性增加，典型原生动物为钟虫（Vorticella sp.）。

| Abstract: | Protozoan community structures and their population dynamics during activated sludge bulking in terms of filamentous bulking and non-filamentous bulking were evaluated.With the excessive growth of filamentous bacteria,a sharp decrease of protozoan abundance occurred,while crawling ciliates and testae amoebae,representatively Chilodonella sp.,Trochilia minuta and Centropyxis sp.appeared as the dominant populations.On the other hand,protozoan community structure during non-filamentous bulking was less affecte... |
