污水处理厂恶臭废气处理的方法有哪些?
Date﹕2020-12-15|Source:Eclear Environmental

       污水处理厂恶臭如何处理,污水处理厂恶臭废气处理解决方法。

       污水处理厂产生恶臭气体的物质通常主要分为两种,分别是有机化合物和无机化合物,有机化合物多为醚类、胺类、酮类、醛类以及低分子脂肪酸等物质,有机化合物容易在污水处理过程中产生化学反应,导致恶臭废气的出现,因此污水处理厂一般都会进行恶臭废气处理。而针对无机化合物,通常利用化学吸收或物理吸附等除臭方法来进行恶臭废气处理

       1、植物吸收隔离除臭法

       植物吸收隔离法主要是通过在污水处理厂周围设置植物丛林带,利用植物吸收废气,从而对污水处理厂的恶臭废气进行除臭,达到净化环境的效果。该法具有低成本、美化污水处理厂周围环境等优点,但也具备明显缺点,即污水除臭的效果不彻底,容易受到天气因素的影响。

       2、吸附剂除臭法

       吸附剂除臭法是污水处理厂应用较广泛的一种除臭方法,该方法主要利用吸附原理对污水散发的恶臭成分进行吸附过滤,吸附所用的主要物质为活性炭。活性炭对气味吸附效果良好,其化学性质较稳定。但使用活性炭吸附除臭需要污水处理厂应用大量的活性炭,同时污水恶臭气体的除臭效果也较为有限。


       3、化学吸收法

       化学吸收法针对有机化合物和无机化合物的除臭方式不同,针对污水处理中有机化合物的恶臭废气,一般使用含有氯气或臭氧的物质在污水处理中的进水管道进行投放,以达到污水废气除臭的目的。而针对污水中的无机化合物,主要是通过化学反应将恶臭气体分解消除。该法在污水处理厂中虽然有所应用,但由于受到化学反应时间、反应条件以及催化剂等多重因素限制,导致成本较高,除臭效果也不太理想。

       4、生物吸收法

       生物吸收除臭法主要有生物过滤法、曝气池法和生物洗涤法。生物过滤法主要是对污水的恶臭废气进行收集,在一定条件下利用微生物对产生臭味的物质进行分解,这种除臭方法具有良好的经济性,且流程较为简易,成本较低,只是需要大量的时间培育微生物,除臭效率较低。曝气池法则是具有活性物质的污泥对污水中的废弃臭味进行分解,这种除臭方式较为简便,且成本低廉,但缺点在于除臭效果较差。

       5、高能离子除臭法

       高能离子除臭法主要是利用离子装置产出高能粒子聚合污水恶臭废气,以达到除臭目的,这种除臭方式能够对污水恶臭废气中的硫化物有效去除,对污水臭气中有害可吸入颗粒也有良好的吸附聚合效果,但高能离子的产出装置成本较高,且对于硫化氢物质及去除效果有待进一步提升。
