生物除臭塔設計

基(ji)本介紹

其基(ji)本特征是在廢(fei)(fei)氣(qi)處理(li)構筑物(wu)(wu)內(nei)(nei)設(she)置(zhi)微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)生(sheng)(sheng)(sheng)(sheng)(sheng)長(chang)聚(ju)集的(de)載體，在充(chong)氧的(de)條件下(xia)，微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)在填料表(biao)面(mian)積(ji)聚(ju)附著形成(cheng)生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜。當廢(fei)(fei)氣(qi)經(jing)過時，生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜中的(de)微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)吸(xi)收分解廢(fei)(fei)氣(qi)中的(de)有機物(wu)(wu)，使廢(fei)(fei)氣(qi)得到凈(jing)化，同時微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)也得到增殖(zhi)，生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜隨之增厚。當生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜增長(chang)到一定厚度，向生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜內(nei)(nei)部擴散的(de)氧受到限制(zhi)，其表(biao)面(mian)仍是好氧狀態，而內(nei)(nei)層(ceng)則(ze)會呈缺氧甚至厭氧狀態，并(bing)zui終導致生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜的(de)脫(tuo)落。隨后，填料表(biao)面(mian)還會繼續生(sheng)(sheng)(sheng)(sheng)(sheng)長(chang)新(xin)的(de)生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)膜，周(zhou)而復始，使廢(fei)(fei)氣(qi)得到凈(jing)化。

生物(wu)除臭塔設計

工作原理

在(zai)(zai)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)塔(ta)反應器內設置填料(liao)(liao)(liao)，廢氣(qi)經過充氧（或(huo)在(zai)(zai)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)塔(ta)底部鼓風曝氣(qi)）后與(yu)(yu)填料(liao)(liao)(liao)相接觸，在(zai)(zai)填料(liao)(liao)(liao)表(biao)面生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)和填料(liao)(liao)(liao)空隙間的(de)活(huo)(huo)(huo)性(xing)污(wu)(wu)泥(ni)(ni)雙重作用下，使廢氣(qi)得到凈化。生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)塔(ta)內裝有填料(liao)(liao)(liao)，大部分(fen)微生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)以(yi)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)的(de)形(xing)式固(gu)著生(sheng)(sheng)(sheng)(sheng)長(chang)于填料(liao)(liao)(liao)表(biao)面，少部分(fen)則以(yi)活(huo)(huo)(huo)性(xing)污(wu)(wu)泥(ni)(ni)的(de)形(xing)式懸(xuan)浮生(sheng)(sheng)(sheng)(sheng)長(chang)于水中。因(yin)此，生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)塔(ta)兼有活(huo)(huo)(huo)性(xing)污(wu)(wu)泥(ni)(ni)法(fa)與(yu)(yu)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)過濾(lv)特性(xing)，是一種(zhong)以(yi)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)法(fa)作用為主、兼有活(huo)(huo)(huo)性(xing)污(wu)(wu)泥(ni)(ni)法(fa)作用的(de)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)處(chu)理工(gong)藝。

結構(gou)構(gou)造(zao)

生(sheng)物塔(ta)的塔(ta)體(ti)為(wei)方型(xing)臥(wo)式，無分段連(lian)接(jie)法蘭。具(ju)體(ti)結構由塔(ta)體(ti)、布水系統、曝氣裝(zhuang)置、生(sheng)物載(zai)體(ti)區、出(chu)水溢(yi)流堰等組(zu)成。
