生物滤池除臭吸收过程
污水站的除臭多使用生物滤池除臭设备。主要是因为生物滤池除臭吸收过程中,环保无二次污染利用微生物的生物化学作用,使污染物分解,转化为无害或少害的物质,同时生物滤池除臭吸收过程中,微生物会利用有机物作为其生长繁殖所需的基质,以此来进行合成代谢用以形成新的细胞物质

           污水站的除臭多使用生物滤池除臭设备。主要是因为生物滤池除臭吸收过程中,环保无二次污染利用微生物的生物化学作用,使污染物分解,转化为无害或少害的物质,同时生物滤池除臭吸收过程中,微生物利用有机物作为其生长繁殖所需的基质以此来进行合成代谢用以形成新的细胞物质

生物滤池除臭吸收过程

生物滤池除臭吸收过程

水溶液中恶臭成分被微生物吸附、吸收,恶臭成分从水中转移至微生物体内。作为吸收剂的水被再生复原,继而再用以溶解新的废气成分。

被吸附的有机物经过生物转化,即通过微生物胞外酶对不溶性和胶体状有机物的溶解作用后才能相继地被微生物摄入体内。如淀粉、蛋白质等大分子有机物在微生物细胞外酶(水解酶)的作用下,被水解为小分子后再进入细胞体内。

生物滤池除臭溶解过程

废气与水或固相表面的水膜接触,污染物溶于水中成为液相中的分子或离子,即恶臭物质由气相转移到液相,这一过程是物理过程,遵循亨利定律:

Pi+=HXi

式中 Pi——可溶气体在气相中的平衡分压,MPa

H——亨利系数,MPa

Xi——可溶气体在液相中的摩尔分数。
