介紹：

其(qi)基本(ben)特征是在(zai)廢(fei)(fei)氣處理(li)構(gou)筑物(wu)(wu)(wu)內(nei)設置(zhi)微(wei)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)生(sheng)(sheng)(sheng)長聚(ju)集的(de)(de)載(zai)體(ti)，在(zai)充氧(yang)的(de)(de)條件下，微(wei)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)在(zai)填料表(biao)面積聚(ju)附著(zhu)形成生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)。當(dang)廢(fei)(fei)氣經過(guo)時，生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)中(zhong)的(de)(de)微(wei)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)吸收(shou)分解廢(fei)(fei)氣中(zhong)的(de)(de)有機物(wu)(wu)(wu)，使(shi)廢(fei)(fei)氣得到(dao)凈(jing)化，同時微(wei)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)也得到(dao)增殖，生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)隨之增厚(hou)。當(dang)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)增長到(dao)一(yi)定厚(hou)度(du)，向(xiang)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)內(nei)部擴散的(de)(de)氧(yang)受到(dao)限制，其(qi)表(biao)面仍是好氧(yang)狀態(tai)，而內(nei)層則會呈缺氧(yang)甚(shen)至(zhi)厭氧(yang)狀態(tai)，并zui終(zhong)導致生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)的(de)(de)脫落(luo)。隨后，填料表(biao)面還會繼續生(sheng)(sheng)(sheng)長新的(de)(de)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜(mo)，周(zhou)而復始(shi)，使(shi)廢(fei)(fei)氣得到(dao)凈(jing)化。

工作原理：

在生(sheng)(sheng)物(wu)(wu)(wu)(wu)塔反應器內(nei)設(she)置填(tian)(tian)料(liao)(liao)，廢氣(qi)經過(guo)(guo)充氧（或在生(sheng)(sheng)物(wu)(wu)(wu)(wu)塔底(di)部鼓風(feng)曝氣(qi)）后與填(tian)(tian)料(liao)(liao)相接觸，在填(tian)(tian)料(liao)(liao)表面(mian)生(sheng)(sheng)物(wu)(wu)(wu)(wu)膜和(he)填(tian)(tian)料(liao)(liao)空隙間(jian)的活性污泥(ni)雙重作(zuo)用(yong)(yong)下，使(shi)廢氣(qi)得到凈化。生(sheng)(sheng)物(wu)(wu)(wu)(wu)塔內(nei)裝有(you)填(tian)(tian)料(liao)(liao)，大部分微生(sheng)(sheng)物(wu)(wu)(wu)(wu)以(yi)生(sheng)(sheng)物(wu)(wu)(wu)(wu)膜的形(xing)(xing)式(shi)固著生(sheng)(sheng)長于填(tian)(tian)料(liao)(liao)表面(mian)，少部分則以(yi)活性污泥(ni)的形(xing)(xing)式(shi)懸(xuan)浮生(sheng)(sheng)長于水中。因此，生(sheng)(sheng)物(wu)(wu)(wu)(wu)塔兼有(you)活性污泥(ni)法(fa)與生(sheng)(sheng)物(wu)(wu)(wu)(wu)過(guo)(guo)濾特性，是一種(zhong)以(yi)生(sheng)(sheng)物(wu)(wu)(wu)(wu)膜法(fa)作(zuo)用(yong)(yong)為主、兼有(you)活性污泥(ni)法(fa)作(zuo)用(yong)(yong)的生(sheng)(sheng)物(wu)(wu)(wu)(wu)處(chu)理工藝(yi)。
