生物除臭设备的应用分析

目前恶臭气体的处理方法越来越多,主要包括吸附法、吸收法、冷凝法、催化氧化法和焚烧法。虽然这些传统的处理方法得到了广泛的应用,但生物除臭设备仍有很大的应用空间。

 

生物处理废气是生物技术与环境工程技术相结合的高新技术。技术环保,操作简单,可在常温常压下反应。特别是在低浓度、高流量的废气净化方面取得了良好的效果。

 生物除臭设备

生物吸收降解技术是利用微生物降解恶臭物质,使其成为氧化产物,从而实现无臭无害化的工艺方法,既不产生二次污染。臭气溶解吸收与微生物降解相结合。降解后的恶臭物质首先溶解在水中,转移到微生物中。通过微生物代谢活动降解。生物吸收降解恶臭气体不需要使用药物;利用微生物分解气味不需要太多的补充能量:生物繁殖、排泄和维持自身生存和活力。材料不需要更换再生。

 

生物吸附降解设备主要由三部分组成统三部分组成;中间是生物填料床;下部是生物循环液降解池,集生物吸收、生物过滤、生物降解于一体。

 

生物填料床中的生物填料由多种材料混合而成,附着大量微生物生长。活性污泥营养液是循环液降解池中的一种。同时,池底配有曝气系统。循环降解池中的活性污泥营养液通过管道由水泵抽出,通过集成设备顶部的喷淋系统均匀喷洒到生物降压填料床上。

 

当恶臭气体从填料床下部通过填料床时,附着在生物填料表面的生物膜和循环降解池中的活性污泥吸收和吸收生物降解。收集到的气味经加湿器装置预处理后进入生化滤池。臭气中的气体污染物由气相体扩散至填料外层的水膜,经填料吸附,最后降解成二氧化碳、水等。如果臭气中所含的营养物质不能满足生物生长的需要,还需要添加营养物质。
