除臭工艺方法可以分为吸收吸附法和燃烧法两大类,常见的方法有化学除臭法、活性炭吸附除臭法、氧离子基团除臭法、燃烧除臭法、纯天然植物提取液喷洒除臭法和生物除臭法等。

市政污水除臭工艺的选择

化学除臭法

化学除臭法是利用化学介质(NaOHNaClNaClO)等无机类致臭成分进行反应,从而达到除臭的目的。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。

活性炭吸附除臭法

活性炭吸附除臭法是利用活性炭能吸附臭气中致臭物质的特点,在吸附塔内设置各种不同性质的活性炭,致臭物质和各种活性炭接触后,排出吸附塔,达到脱臭的目的。活性炭达到饱和后,需通过热空气、蒸汽或NaOH浸没进行再生或替换。活性炭的再生与替换价格较昂贵、劳动强度大且再生后的活性炭吸附能力降低。

氧离子基团除臭法

氧离子基团除臭法是利用高压静电装置,在新风补给空气中产生氧离子基团,在常温常压下将恶臭物质分解成二氧化碳和水或是部分氧化的化合物的方法。

上海羿清环保专注于生物除臭,在市政污水除臭方面有着丰富的案例,其生产的生物滤池臭气处理设备能够有效处理恶臭气体,受到业内人士的一致赞誉。
