目前,恶臭废气严重困扰人们的生活,生物法恶臭废气处理工艺受到广泛应用。那么,恶臭废气处理的除臭机理和工艺是怎样的?具体如何?接下来,我将具体介绍一下生物法恶臭废气处理的除臭机理和工艺

恶臭废气处理的除臭机理和工艺

生物法除臭机理

生物除臭的原理是微生物利用恶臭废气中的有机物作为生命活动的碳源和能源,并将其转化为二氧化碳、水和细胞物质,这一点与废水生物处理的原理是一致的。但是,微生物的生命活动离不开水,通常的微生物总是生长在液体中或者固体表面,因此废气中的污染物首先要经历由气相转到液相或固相表面液膜中的传质过程,然后才能在液相或固相表面被微生物吸收降解。用来进行气态污染物降解的微生物主要是异养菌,在适当的营养条件、温度、酸碱度和有氧的条件下,此类微生物能较快地完成污染物质的降解。与废水的生物处理一样,气态污染物的生物净化过程也是人类对自然过程的强化与工程控制,其过程的速度取决于气相向液固相的传质速率,生物降解速率,还有能起降解作用的活性生物质的量。

生物法的动力学理论

按照传统生物膜理论,生物法处理恶臭废气一般要经历以下步骤:

(1) 废气中的有机污染物首先与水接触,并溶解于水中;

(2) 溶解于液膜中的有机污染物成分在浓度差的推动下进一步扩散到生物膜,进而被微生物捕获并吸收;

(3) 微生物以有机物为能源或碳源进行生长代谢,从而将其分解为简单无毒的无机物和低毒的有机物;

(4) 生物代谢产物一部分重新回到液相,一部分气态物质脱离生物膜,通过扩散进入大气。依据该理论,生物净化恶臭气体的速率主要取决于气相和液相中有机物的扩散速率及生化反应速率。

上海羿清环保公司生产的生物法恶臭废气处理设备能够有效处理废气,而且具有不耗材、低污染、高效环保等优点,受到业内人士广泛好评。
