       污水站恶臭废气如何处理?污水除臭方法有哪些?想必这是对有污水排放需求的人都会思考的问题。那么,污水站恶臭废气处理的方法有哪些呢?除臭方法经历了一个发展过程,目前常用的除臭方法有活性炭吸附法、生物脱臭法、活性氧技术和光催化技术。

生物除臭滤池


       1、活性炭吸附法

       活性炭吸附法是利用活性炭能吸附臭气中含臭物质的特点,达到脱臭的目的。为了有效地脱臭,通常利用各种不同性质的活性炭,在吸附塔内设置吸附酸性物质的活性炭,吸附碱性物质的活性炭和吸附中性物质的活性炭,臭气和各种活性炭接触后,排出吸附塔。

       活性炭吸附法常用于低浓度臭气和脱臭装置的后处理。

       2、生物脱臭法

       在过去的30年内,生物除臭技术已在欧洲广泛地得到应用,北美洲也应用在除臭方面。生物除臭主要利用微生物去除及氧化气体中的致臭成份,气体流经生物活性滤料,滤料上面的菌种就会分解致臭物质,产生二氧化碳及水气。

       微生物寄生在潮湿的滤料上生长出一层薄薄的生物膜,当致臭物质流经滤料时,被吸附并被氧化。

       生物除臭法的优点:

       运行管理简单

       投资费用及运行、维护费用均低于其它除臭工艺

       应用范围广泛,包括:H2S、CS2、氨氮、有机硫化物等

       3、活性氧技术

       利用高频高压静电的特殊脉冲放电方式(活性氧发射管每秒钟发射上千亿个高能离子),产生高密度的高能活性氧(介于氧分子和臭氧之间的一种过渡态氧),迅速与污染物分子碰撞,激活有机分子,并直接将其破坏;或者高能活性氧激活空气中的氧分子产生二次活性氧,与有机分子发生一系列链式反应,并利用自身反应产生的能量维系氧化反应,进一步氧化有机物质,生成二氧化碳和水以及其他小分子,而且可以在极短的时间内达到很高的处理效率。

       4、光催化技术

       光催化技术是一种新型的复合纳米高科技功能的技术,其基本原理是利用光催化纳米粒子在一定波长的紫外光线照射下受到激发生成电子—空穴对,同时在氧及水的参与下,空穴分解催化剂表面吸附的水产生强氧化性的羟基自由基(•OH),羟基自由基(•OH),电子使其周围的氧还原成活性离子氧,从而具备极强的氧化-还原作用,利用其强氧化性,将光催化纳米粒子表面的各种污染物氧化,氧化分解空气中低浓度的化学污染物使其无害化,从而达到净化空气的目的。
