The long-term project on the survey of filamentous microorganisms, which started in 1996, was finished in 2000 by the survey of eight Czech activated sludge plants with biological nutrient removal (BNR) systems. At all plants with enhanced biological nutrient removal, specific microbial population (mostly from the point of view of filaments occurrence), operational problems (presence of biological foaming, bulking) and plant operation were observed periodically and longer than 1 year. In our paper the relationship between the composition of activated sludge (especially filaments) consortia and modification of the process with nutrient removal is discussed. At the surveyed plants Type 0092 and Microthrix parvicella were identified as dominant Eikelboom filamentous types.
始于1996年的丝状微生物调查长期项目，于2000年通过对8个采用生物除磷脱氮（BNR）系统的捷克活性污泥厂进行调查而完成。在所有具有强化生物除磷脱氮功能的工厂中，定期观察特定微生物群落（主要从丝状菌出现的角度）、运行问题（生物泡沫、污泥膨胀的存在情况）以及工厂运行情况，观察期超过1年。在我们的论文中，讨论了活性污泥（尤其是丝状菌）群落组成与营养物去除工艺改进之间的关系。在所调查的工厂中，0092型和细小微丝菌被确定为艾克布姆丝状菌的优势类型。
