生物洗滌塔設計

基本(ben)介紹(shao)

其基本特征(zheng)是在(zai)廢(fei)(fei)(fei)氣(qi)(qi)處理(li)構筑物內(nei)設置(zhi)微生(sheng)(sheng)(sheng)(sheng)(sheng)物生(sheng)(sheng)(sheng)(sheng)(sheng)長聚(ju)集(ji)的(de)(de)載體，在(zai)充氧(yang)的(de)(de)條件下，微生(sheng)(sheng)(sheng)(sheng)(sheng)物在(zai)填料表(biao)(biao)面(mian)積(ji)聚(ju)附著形成生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)。當廢(fei)(fei)(fei)氣(qi)(qi)經過時(shi)，生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)中的(de)(de)微生(sheng)(sheng)(sheng)(sheng)(sheng)物吸收分解廢(fei)(fei)(fei)氣(qi)(qi)中的(de)(de)有機(ji)物，使(shi)(shi)廢(fei)(fei)(fei)氣(qi)(qi)得(de)到(dao)(dao)凈化，同(tong)時(shi)微生(sheng)(sheng)(sheng)(sheng)(sheng)物也得(de)到(dao)(dao)增(zeng)(zeng)殖，生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)隨(sui)之(zhi)增(zeng)(zeng)厚。當生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)增(zeng)(zeng)長到(dao)(dao)一定(ding)厚度，向生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)內(nei)部擴散的(de)(de)氧(yang)受到(dao)(dao)限(xian)制，其表(biao)(biao)面(mian)仍是好氧(yang)狀態(tai)(tai)，而(er)(er)內(nei)層則(ze)會呈(cheng)缺氧(yang)甚至厭氧(yang)狀態(tai)(tai)，并zui終導(dao)致生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)的(de)(de)脫落。隨(sui)后，填料表(biao)(biao)面(mian)還會繼續生(sheng)(sheng)(sheng)(sheng)(sheng)長新的(de)(de)生(sheng)(sheng)(sheng)(sheng)(sheng)物膜(mo)，周(zhou)而(er)(er)復始(shi)，使(shi)(shi)廢(fei)(fei)(fei)氣(qi)(qi)得(de)到(dao)(dao)凈化。

生物洗滌塔設計

工(gong)作原理

在(zai)生(sheng)(sheng)(sheng)物塔反(fan)應器內設置(zhi)填(tian)料(liao)，廢(fei)氣(qi)經過充氧(yang)（或在(zai)生(sheng)(sheng)(sheng)物塔底部鼓風曝(pu)氣(qi)）后(hou)與填(tian)料(liao)相接觸，在(zai)填(tian)料(liao)表(biao)面生(sheng)(sheng)(sheng)物膜和(he)填(tian)料(liao)空隙間的(de)活性污泥(ni)雙重作(zuo)用下，使廢(fei)氣(qi)得到凈化。生(sheng)(sheng)(sheng)物塔內裝有填(tian)料(liao)，大(da)部分微生(sheng)(sheng)(sheng)物以生(sheng)(sheng)(sheng)物膜的(de)形式(shi)固著(zhu)生(sheng)(sheng)(sheng)長(chang)于填(tian)料(liao)表(biao)面，少(shao)部分則以活性污泥(ni)的(de)形式(shi)懸浮(fu)生(sheng)(sheng)(sheng)長(chang)于水中(zhong)。因此(ci)，生(sheng)(sheng)(sheng)物塔兼有活性污泥(ni)法與生(sheng)(sheng)(sheng)物過濾特性，是(shi)一種(zhong)以生(sheng)(sheng)(sheng)物膜法作(zuo)用為主、兼有活性污泥(ni)法作(zuo)用的(de)生(sheng)(sheng)(sheng)物處理(li)工藝。

結構(gou)(gou)構(gou)(gou)造

生物(wu)塔的(de)塔體為方型(xing)臥式，無分段連接(jie)法蘭。具體結構由(you)塔體、布水系統、曝氣裝置、生物(wu)載體區、出水溢流堰(yan)等組(zu)成。
