生物降解塔介紹

基本介紹(shao)

其(qi)基(ji)本特征是在廢氣處理構筑物(wu)(wu)(wu)(wu)內設置微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)生(sheng)(sheng)(sheng)(sheng)(sheng)長(chang)聚集的(de)(de)載(zai)體，在充(chong)氧的(de)(de)條件下，微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)在填料表(biao)面(mian)(mian)積(ji)聚附著形成生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)。當廢氣經過時，生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)中的(de)(de)微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)吸收分解廢氣中的(de)(de)有機物(wu)(wu)(wu)(wu)，使(shi)廢氣得(de)到凈化(hua)(hua)，同時微生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)也得(de)到增殖，生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)隨之增厚。當生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)增長(chang)到一定厚度，向生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)內部擴散(san)的(de)(de)氧受到限制(zhi)，其(qi)表(biao)面(mian)(mian)仍是好氧狀態，而內層則會(hui)呈缺氧甚(shen)至厭氧狀態，并zui終(zhong)導致(zhi)生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)的(de)(de)脫落。隨后，填料表(biao)面(mian)(mian)還會(hui)繼續生(sheng)(sheng)(sheng)(sheng)(sheng)長(chang)新(xin)的(de)(de)生(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)膜(mo)(mo)，周而復始(shi)，使(shi)廢氣得(de)到凈化(hua)(hua)。

工作原理

在(zai)生(sheng)(sheng)物(wu)(wu)(wu)塔反應器內(nei)設(she)置填料(liao)(liao)，廢(fei)氣經過(guo)充氧（或在(zai)生(sheng)(sheng)物(wu)(wu)(wu)塔底部鼓(gu)風曝(pu)氣）后與(yu)(yu)填料(liao)(liao)相接(jie)觸(chu)，在(zai)填料(liao)(liao)表面生(sheng)(sheng)物(wu)(wu)(wu)膜(mo)(mo)和填料(liao)(liao)空隙間(jian)的(de)(de)(de)活性(xing)(xing)(xing)污(wu)泥(ni)雙重作用(yong)下(xia)，使(shi)廢(fei)氣得到凈化(hua)。生(sheng)(sheng)物(wu)(wu)(wu)塔內(nei)裝有填料(liao)(liao)，大(da)部分微生(sheng)(sheng)物(wu)(wu)(wu)以(yi)生(sheng)(sheng)物(wu)(wu)(wu)膜(mo)(mo)的(de)(de)(de)形(xing)式(shi)固著生(sheng)(sheng)長于(yu)填料(liao)(liao)表面，少部分則以(yi)活性(xing)(xing)(xing)污(wu)泥(ni)的(de)(de)(de)形(xing)式(shi)懸浮生(sheng)(sheng)長于(yu)水中。因(yin)此，生(sheng)(sheng)物(wu)(wu)(wu)塔兼有活性(xing)(xing)(xing)污(wu)泥(ni)法(fa)與(yu)(yu)生(sheng)(sheng)物(wu)(wu)(wu)過(guo)濾特性(xing)(xing)(xing)，是一種以(yi)生(sheng)(sheng)物(wu)(wu)(wu)膜(mo)(mo)法(fa)作用(yong)為主、兼有活性(xing)(xing)(xing)污(wu)泥(ni)法(fa)作用(yong)的(de)(de)(de)生(sheng)(sheng)物(wu)(wu)(wu)處(chu)理工藝。

結構(gou)構(gou)造

生物塔(ta)的塔(ta)體為方(fang)型臥式(shi)，無分段連(lian)接法(fa)蘭(lan)。具體結構由塔(ta)體、布(bu)水系統、曝氣裝置、生物載體區(qu)、出水溢(yi)流堰等組成。
