由于生物除臭滤池除臭效果较好,而且没有二次污染产生,已经得到广泛应用。那么,除了生物除臭滤池以外,还有哪些除臭方法,接下来我将具体介绍一下。

生物除臭滤池

吸附法

将恶臭气体通过吸附剂吸附去除,常用吸附剂一般为活性炭、硅藻土等。活性炭吸附除臭法是在吸附塔内设置各种不同性质的活性炭填充层,利用活性炭对致臭物质的吸附作用达到脱臭目的。活性炭除臭工艺是一种高效的除臭技术,对恶臭物质有较大的平衡吸附量,对多种恶臭气体都可达到较好的吸附效果。活性炭吸附除臭法运行费用高,需定期维护(如再生或更换活性炭),故常用于低浓度臭气处理和脱臭的后处理。不受经济约束,且对臭气处理效果要求较高的污水处理厂可采用此法对臭气进行后处理。

燃烧除臭法

根据恶臭物质的特点,在控制一定的温度和接触时间的条件下使臭气直接燃烧,达到脱臭的目的。对于高浓度臭气处理用直接燃烧法是有效的,但是燃料费用高,燃烧后的气体中存在NO等化学成分,有二次污染的可能。

化学吸收除臭法

利用化学介质(NaOHNaClO)H2SNH3等致臭成分进行反应,达到除臭的目的。该法对硫化氢等的吸收比较彻底,速度快;但对硫醇、挥发性脂肪酸或其他挥发性有机化合物的去除比较困难,不能保证完全消除异味。

臭氧除臭法

利用臭氧的强氧化性,使臭气中的化学成分氧化分解,以达到脱臭目的。在条件适宜时,臭氧与硫化氢的反应速度极快。

上海羿清环保公司是一家专注于生物除臭的环保公司,其生产的生物除臭滤池设备能够有效处理恶臭气体,而且不会产生二次污染,受到业内人士的一致认可。
