污水处理站臭气处理中生物除臭技术的应用

焦化废水

污水处理站臭气的来源和主要成分

污水处理站臭气主要来源于以下处理系统:预处理系统,由于污水源水中有机物含量高,导致水中缺氧,然后在厌氧菌的作用下产生大量臭气,使源水中的臭气挥发进入空气;生化处理系统中,污水的生化处理一般包括厌氧和好氧处理,其中厌氧过程大大增加了排放的臭气体量;污泥浓缩脱水系统,通过压缩、过滤、离心分离等过程进行污泥浓缩脱水,会因搅拌而排放臭气体。

污水处理站产生的臭味成分是蛋白质、脂肪、碳水化合物的微生物呼吸、发酵过程的产物和不完全产物,一般分为含硫化合物、硫化氢、甲硫醇、甲基硫醚等氮化合物、氨三甲胺碳、氢或碳、氢、氧化合物、低级醇、醛、脂肪酸。

污水处理站臭气常用处理方法。

生物除臭技术

包含生物过滤法和生物吸收法。

1)生中含有恶臭物质的气体从过滤器的底部从下向上通过过滤器,通过过滤器时恶臭物质从气相转移到生物层,由于附着在过滤器上的微生物的代谢作用分解为CO2、H2O等物质。技术成熟,是目前处理恶臭气体最常用的方法。

2)生物吸收法是利用生物洗涤塔和洗涤塔中培养的微生物,有效吸附分解臭气,达到处理目的。

以上是羿清环保针对污水处理站生物除臭技术的介绍,希望对您有所帮助。
