污水废气处理成为环保部门重点解决的问题,也是一些厂家需要解决的问题。那么,污水废气处理的工艺种类有哪些呢?具体是什么呢?接下来,我将具体介绍一下常见的污水废气处理的工艺种类。

污水废气处理的工艺种类

生物法

物法净化VOC废气是近年来发展起来的空气污染控制技术,它比传统工艺投资少,运行费用低,操作简单,应用范围广,是最有希望替代燃烧法和吸附净化法的新技术。

VOC废气的生物法净化实质上是利用微生物的生命活动将废气中的有害物质转变成简单的无机物(C02H20)及细胞物质等,主要工艺有生物洗涤法、生物过滤法和生物滴滤法三种。

有机废气生物处理是一项新的技术,由于反应器涉及到气、液/固相传质及生化降解过程,影响因素多而复杂,有关的理论研究及实际应用还不够深入、广泛,许多问题需要进一步探讨和研究,主要包括建立准确的反应动力学模式:填料特性以及如何克服颗粒物在滤床中积累造成的堵塞;动态负荷(浓度和废气流量波动较大)的调控;最适工艺参数的确定;高浓度有机废气的治理:适合于特定有机物降解的细菌种类和接种方法等。

膜分离

分离技术是采用对有机物具有选择性渗透的高分子膜,在一定的压力下使VOC渗透而达到分离的目的。当VOC气体进入膜分离系统后,膜选择性地让VOC气体通过而被富集,脱除了VOC的气体留在未渗透侧,可以达标排放;富集了VOC的气体可去冷凝回收系统进行有机溶剂的回收。选择此方法回收废气中的丙酮、四氢呋喃、甲醇、乙腈、甲苯等,回收率可达97%以上。目前,该方法正迅速发展成为石油化工、制药、食品加丁等行业回收VOC的有效方法。
