Abstract

Assessment of protozoan populations is an important tool in evaluating the efficiency of activated sludge in the treatment of wastewater. In this process, protozoa play a significant role by grazing on dispersed bacteria, supporting a healthy food web in activated sludge artificial ecosystems. The objective of this study was to verify how the success of the purification process in activated sludge plants, mainly in terms of TSS, BOD, and COD, is related to ciliate protozoa communities and the presence of filamentous bacteria. Samples were collected from five water treatment plants in the Puglia region, in the period May 2007 - April 2008. Microfauna and filamentous bacteria were identified and quantified, and the sludge biotic index calculated. The data show a correlation between the biological components of activated sludge and traditional chemical parameters. Our results indicate that biological analyses represent a valid alternative to traditional chemical testing in assessing the performance of activated sludge systems.

摘要

评估原生动物种群是评估活性污泥处理废水效率的一项重要工具。在此过程中，原生动物通过捕食分散的细菌发挥着重要作用，从而在活性污泥人工生态系统中维持健康的食物网。本研究的目的是验证活性污泥处理厂中净化过程的成功程度（主要体现在总悬浮固体、生化需氧量和化学需氧量方面）与纤毛虫原生动物群落以及丝状细菌的存在之间的关系。2007年5月至2008年4月期间，从普利亚地区的五个水处理厂采集了样本。对微型动物区系和丝状细菌进行了识别和定量，并计算了污泥生物指数。数据表明活性污泥的生物成分与传统化学参数之间存在相关性。我们的结果表明，在评估活性污泥系统的性能时，生物分析是传统化学检测的有效替代方法。
