生物除臭塔的原理是什么?
Date﹕2021-11-21|Source:Eclear Environmental

生物除臭塔适用于处理常温、大风量、中等浓度、易挥发的有机废气(臭气)。生物除臭塔采用生物法,通过培养微生物膜处理废气和恶臭气体分子。生物除臭塔通常采用预处理,如喷水除去气中的灰尘和异味,降低气中的氨和二氧化硫,调节气的pH值,然后通过培养的微生物膜对废气和异味气体分子进行处理,通过气体预处理为后续微生物的生长繁殖创造条件

生物除臭塔的原理

生物除臭塔填料的选择:生物除臭塔的主体是填料。良好的载体填料需符合以下要求:允许生长的微生物种类丰富;为微生物栖息地和生长提供较大的比表面积;合理的营养成分(氮、磷、钾和微量元素);吸水性好;无异味;吸附性好;结构均匀,孔隙率高;材料随时可得,且易于使用;抗老化;操作和维护简单。

生物除臭塔的填料堆放程度取决于所需的停留时间和表面负荷。填料度一般为1.0~1.2m。如果选择合适的填充物,空气分布可以均匀,气流短路可以消除。

生物除臭的塔点:

1除臭效果好

2.无二次污染

3.微生物可以依靠填料中的有机物生长,而无需添加额外的营养素。因此,可在停机后使用。启动速度很快。周末停机或停机1-2周后重新启动可立即达到除臭效果。

4.缓冲容量大,可自动调节浓度峰值,使微生物始终正常工作,抗冲击负荷能力强
