生物滤池的构成原理是什么?

在工业废水处理中,采用生物处理时,可根据实际水质选用生物滤池进行废水处理。那么,什么是生物滤池呢,生物滤池处理废水采用的是什么原理呢?

生物滤池通常是由池体、砾石或塑料产品填料、配水装置和排水系统组成的生物处理结构。类型可分为普通生物滤池、高负荷生物滤池和塔式生物滤池。

滤池内设置固定滤料,废水通过配水装置从顶部流向池体内。废水通过固定滤料后,与滤料不断接触。因此,微生物聚集在滤料表面进行代谢,逐渐形成一层生物膜。生物膜是由多种微生物组成的生态系统。它不断地从饲料废水中吸收有机污染物作为自身的营养源,从而在生物膜形成后的一段时间内不断产生新的微生物,形成生物膜。

当微生物达到一定厚度时,由于微生物的不断积累和繁殖,氧气不能进入生物膜的内层,导致内部厌氧状态,降低内部微生物活性,减弱粘附力。废水继续冲击过滤材料并进入罐体。生物膜附着力不足,逐渐开始脱落。脱落后,污水的连续接触会在一个周期内在滤料上生长新的生物膜。废水经过生物膜后即可净化。

这就是生物滤池的构成原理。如果您想了解更多关于生物滤池的信息,请关注羿清环保。您将在后续文章中继续了解更多相关知识。羿清环保,专注于废水处理,在废水处理和质量保证方面拥有丰富经验。
