Microbiology of Autothermal Thermophilic Aerobic Digester (ATAD) Systems for Biosolids Disposal in Wastewater Treatment Systems

处理废水处理厂的生物固体既昂贵又麻烦。ATAD系统利用微生物，据称克服了传统处理方法的许多问题。维多利亚州中部的工厂已经安装了两个。然而，人们对它们的微生物学几乎一无所知。这项研究将确定哪些微生物种群存在并负责生物固体的消化，这些种群如何随着操作条件的变化而变化，以及这些种群的变化是否与气味的产生有关。这些信息将使这些消化器得到更好的管理和操作。

The disposal of biosolids from wastewater treatment plants is expensive and troublesome. ATAD systems utilise microbes and are claimed to overcome many of the problems of more conventional disposal methods. Two have been installed in plants in central Victoria. However, virtually nothing is known about their microbiology. The study will determine which microbial populations are present and responsible for biosolids digestion, how these populations might change with changing operational conditions, and whether these changes in populations relate to production of odors. This information will enable these digesters to be better managed and operated.
