Development of an improved fixed-film media support for wastewater treatment

废水的生物处理通常分为悬浮生长法和固定膜生长法。这两种方法通常用于废水处理，但固定膜法具有明显的优势。其中一些好处包括：增加生物量保留，增加对废水波动的抵抗力，增加对抗菌素化合物存在的抵抗力。典型的固定膜材料成本为150美元/立方米，比表面积为100 - 200平方米/立方米，空隙体积比大于95%。固定膜处理没有在污水处理设施中更常规地实施的一个关键驱动因素/理由是相对较高的资本支出成本（通常为150美元/立方米）。本研究的主要目的是开发一种改进的固定胶片介质

The biological treatment of wastewater is typically divided into either a suspension growth method or a fixed-film growth method. Both methods are routinely used in waste water treatment, however distinct advantages are associated with the fixed film process. Some of these benefits include: increased biomass retention, increased resistance to waste water fluctuations, increased resistance to the presence of antimicrobial compounds. Typical fixed-film materials cost >$150/m3, contain a specific surface area of 100 - 200 m2/m3 and utilize a void to volume ratio greater than 95%. A key driver / rationale for fixed-film treatment not being more routinely implemented in wastewater treatment facilities are the comparatively high capital expenditure costs (typically > $150/m3). The main goal of this study is the development of an improved fixed film media
