本研究的目的是确定活性污泥微型动物，污泥生物指数（SBI）和全面的城市污水处理厂（WWTP）的出水水质与冲击有机和铵负荷所造成的定期从化粪池输送废水之间的关系。无论COD、BOD（5）、铵和悬浮固体方面的高/低流出物质量如何，观察到高SBI值（8-10），其对应于污泥的第一质量等级。高SBI值与丰富的分类组成和爬行纤毛虫与带壳变形虫和附着纤毛虫的统治。高SBI值，即使在低的出水水质，限制了有用的指标监测的活性污泥系统的状态和城市污水处理厂处理的污水从化粪池的出水水质。结果表明，一个更敏感的指标，污水质量的变化是丰富的附着纤毛虫与一个狭窄的口（Vorticella infusionum和Opercularia coarctata），小鞭毛虫和爬行纤毛虫（Acineria uncinata）喂养鞭毛虫。(C)2011年Elsevier GmbH。All rights reserved.
This study aimed to determine the relationship between activated sludge microfauna, the sludge biotic index (SBI) and the effluent quality of a full-scale municipal wastewater treatment plant (WWTP) working with shock organic and ammonium loadings caused by periodic wastewater delivery from septic tanks. Irrespective of high/low effluent quality in terms of COD, BOD(5), ammonium and suspended solids, high SBI values (8-10), which correspond to the first quality class of sludge, were observed. High SBI values were connected with abundant taxonomic composition and the domination of crawling ciliates with shelled amoebae and attached ciliates. High SBI values, even at a low effluent quality, limit the usefulness of the index for monitoring the status of an activated sludge system and the effluent quality in municipal WWTP-treated wastewater from septic tanks. It was shown that a more sensitive indicator of effluent quality was a change in the abundance of attached ciliates with a narrow peristome (Vorticella infusionum and Opercularia coarctata), small flagellates and crawling ciliates (Acineria uncinata) feeding on flagellates.
