隨著(zhu)近幾年生物除臭技術(shu)的發展，各種(zhong)生物除臭技術(shu)蓬勃發展。那(nei)么(me)，生物除臭技術(shu)的種(zhong)類(lei)有哪些呢？具(ju)體是(shi)怎樣(yang)的呢？

　　生(sheng)物(wu)(wu)(wu)(wu)滴(di)濾(lv)池，生(sheng)物(wu)(wu)(wu)(wu)滴(di)濾(lv)池的(de)結構和生(sheng)物(wu)(wu)(wu)(wu)濾(lv)池相(xiang)似，不同(tong)的(de)是所用填料是不能提(ti)供(gong)營(ying)養物(wu)(wu)(wu)(wu)質的(de)惰性(xing)填料。生(sheng)物(wu)(wu)(wu)(wu)滴(di)濾(lv)池可以承受(shou)比生(sheng)物(wu)(wu)(wu)(wu)濾(lv)池更高(gao)的(de)污染(ran)物(wu)(wu)(wu)(wu)負荷，同(tong)時(shi)它還具有(you)緩沖能力，對于(yu)處理鹵化(hua)物(wu)(wu)(wu)(wu)、硫化(hua)物(wu)(wu)(wu)(wu)和含氮化(hua)合物(wu)(wu)(wu)(wu)會產生(sheng)酸性(xing)污染(ran)物(wu)(wu)(wu)(wu)，生(sheng)物(wu)(wu)(wu)(wu)滴(di)濾(lv)系統(tong)更容易(yi)調整pH值。

　　生(sheng)(sheng)(sheng)(sheng)物(wu)生(sheng)(sheng)(sheng)(sheng)物(wu)除(chu)臭(chou)(chou)濾(lv)(lv)池，生(sheng)(sheng)(sheng)(sheng)物(wu)濾(lv)(lv)池脫臭(chou)(chou)是目前最早、最常用(yong)(yong)的生(sheng)(sheng)(sheng)(sheng)物(wu)除(chu)臭(chou)(chou)技(ji)術(shu)。生(sheng)(sheng)(sheng)(sheng)物(wu)濾(lv)(lv)池的生(sheng)(sheng)(sheng)(sheng)物(wu)相(xiang)和液(ye)(ye)相(xiang)不流通，且僅有一(yi)個反應器，氣(qi)液(ye)(ye)的接(jie)觸(chu)面積比(bi)較大(da)，所以運行的費用(yong)(yong)比(bi)較低(di)，不需額外(wai)加(jia)營(ying)養物(wu)質，處(chu)(chu)理(li)的效率比(bi)較高，適(shi)宜處(chu)(chu)理(li)流量大(da)的廢氣(qi)。當(dang)前，生(sheng)(sheng)(sheng)(sheng)物(wu)濾(lv)(lv)池得到了(le)廣(guang)泛應用(yong)(yong)。

　　從目(mu)前國(guo)內的市(shi)政污水廠采用的工藝來看，生(sheng)(sheng)物濾池由(you)于其(qi)運(yun)行(xing)成本(ben)低、處(chu)理效率高，其(qi)應(ying)用范圍要(yao)遠遠大(da)于生(sheng)(sheng)物滴(di)濾池和(he)生(sheng)(sheng)物洗滌(di)器。

　　生物除(chu)臭生物法對(dui)惡(e)臭污染物的治理原理如(ru)下：

　　①惡臭(chou)氣(qi)體的溶解過程。廢氣(qi)與水(shui)(shui)或固相(xiang)表面的水(shui)(shui)膜接(jie)觸，污染物溶于(yu)水(shui)(shui)中(zhong)成(cheng)為液相(xiang)中(zhong)的分子(zi)或離子(zi)，即惡臭(chou)物質由氣(qi)相(xiang)轉(zhuan)移到液相(xiang)，這一過程是物理(li)過程，遵循亨(heng)利定(ding)律；

　　②惡臭物(wu)(wu)(wu)質的(de)(de)(de)吸(xi)附(fu)、吸(xi)收(shou)(shou)過程(cheng)。水溶(rong)(rong)(rong)液中惡臭成分(fen)(fen)被微(wei)生(sheng)物(wu)(wu)(wu)吸(xi)附(fu)、吸(xi)收(shou)(shou)，惡臭成分(fen)(fen)從水中轉移至(zhi)微(wei)生(sheng)物(wu)(wu)(wu)體(ti)內(nei)。作(zuo)為吸(xi)收(shou)(shou)劑的(de)(de)(de)水被再生(sheng)復(fu)原，繼而再用(yong)(yong)以溶(rong)(rong)(rong)解新的(de)(de)(de)廢氣成分(fen)(fen)。被吸(xi)附(fu)的(de)(de)(de)有(you)機(ji)物(wu)(wu)(wu)經(jing)過生(sheng)物(wu)(wu)(wu)轉化(hua)，即通過微(wei)生(sheng)物(wu)(wu)(wu)胞(bao)外酶對不溶(rong)(rong)(rong)性和膠體(ti)狀有(you)機(ji)物(wu)(wu)(wu)的(de)(de)(de)溶(rong)(rong)(rong)解作(zuo)用(yong)(yong)后才能(neng)相繼地被微(wei)生(sheng)物(wu)(wu)(wu)攝入體(ti)內(nei)。如淀粉、蛋白(bai)質等(deng)大分(fen)(fen)子有(you)機(ji)物(wu)(wu)(wu)在微(wei)生(sheng)物(wu)(wu)(wu)細胞(bao)外酶(水解酶)的(de)(de)(de)作(zuo)用(yong)(yong)下，被水解為小分(fen)(fen)子后再進入細胞(bao)體(ti)內(nei)。由此(ci)可見(jian)，當以污泥(ni)或膜形態存在的(de)(de)(de)微(wei)生(sheng)物(wu)(wu)(wu)表面一(yi)旦(dan)通過吸(xi)附(fu)而被有(you)機(ji)物(wu)(wu)(wu)覆蓋后，其進一(yi)步吸(xi)附(fu)的(de)(de)(de)作(zuo)用(yong)(yong)將受到(dao)限制(zhi)，因(yin)而需要通過膜的(de)(de)(de)表面更新或不斷補充具有(you)吸(xi)附(fu)能(neng)力的(de)(de)(de)微(wei)生(sheng)物(wu)(wu)(wu)菌膠團，才能(neng)保證(zheng)此(ci)過程(cheng)的(de)(de)(de)順利(li)進行。生(sheng)物(wu)(wu)(wu)除臭
