生物除臭采用的生物洗涤器

生物洗涤器是一个悬浮活性污泥处理系统,由一个吸收室和一个再生池构成。生物悬浮液(循环液)自吸收室顶部喷淋而下,使废气中的污染物转移至液相,实现传质过程。吸收了废气中的有机物的生物悬浮液流入再生反应器中,通入空气充氧再生。

生物除臭

被吸收的有机物通过微生物氧化作用,最终被再生池中的生物悬浮液从液相去除。最常见的生物悬浮液是活性污泥悬浮液,但其处理后再生的时间较长,需要几个小时。由于吸收和再生所需的时间不同,因此生物悬浮液的再生是在同一个反应器中进行,还是在另一个反应器中完成,取决于生物悬浮液的活性强度和再生能力。洗涤器中气液相的接触方法除液相喷淋法,还可采用气相鼓泡法,这取决于吸收过程中何者为控制步骤。若气相阻力较大则用喷淋法,反之液相阻力较大时可用鼓泡法。

生物洗涤器的特点是:液相和生物相均循环流动,生物为悬浮状态,洗涤器中有一定生物量和生物降解作用。其优点是压降低,填料不易堵塞;但设备多,需外加营养物,成本较高,反应条件难控制,操作维护难度高,普通污水处理人员难掌握,需配备专业人员管理。不适应较长时间间歇运行的条件。填料比表面积小,限制了微溶化合物的应用范围,也不适用于非水溶性化合物的处理。

上海羿清环保是一家专注于生物除臭的环保公司,其生产的生物除臭设备能够有效处理恶臭气体,受到业内人士的一致赞誉。
