惡臭氣體不僅對(dui)生(sheng)(sheng)態環境造成(cheng)嚴(yan)重影(ying)響(xiang)，而且(qie)對(dui)人體健康具(ju)有(you)很大(da)的危(wei)害，會(hui)使中(zhong)樞神經(jing)產(chan)生(sheng)(sheng)障礙、病(bing)變(bian)，引起慢性(xing)(xing)病(bing)、急性(xing)(xing)病(bing)。雜環香(xiang)料的閾值低(di)、氣味(wei)(wei)強度(du)大(da)且(qie)不愉快，在(zai)生(sheng)(sheng)產(chan)和(he)包裝過程中(zhong)極易(yi)有(you)大(da)量的氣味(wei)(wei)逸出，對(dui)公(gong)司內(nei)部和(he)周邊人群易(yi)造成(cheng)身心不愉快。該廠產(chan)生(sheng)(sheng)的廢氣濃度(du)較(jiao)低(di)，成(cheng)分(fen)復雜，監測難度(du)大(da)，治理困(kun)難。國外早(zao)在(zai)20世紀50年代末(mo)便開(kai)始了惡臭氣體污(wu)染治理的研究(jiu)，并積累了豐(feng)富的理論(lun)知識和(he)實踐經(jing)驗。

新型生物除臭設備是采用生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)法(fa)通(tong)(tong)過(guo)專門培養在生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)濾池內(nei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)填料上(shang)的微生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)膜(mo)(mo)對(dui)廢(fei)臭氣(qi)分子進行除(chu)臭的生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)廢(fei)氣(qi)處理(li)技術。當含有氣(qi)、液、固三項混合的有毒、有害、有惡臭的廢(fei)氣(qi)經收集(ji)管(guan)道導入本系統后通(tong)(tong)過(guo)培養生(sheng)(sheng)(sheng)(sheng)長在生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)填料上(shang)的微生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)菌株形成的生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)膜(mo)(mo)來凈化和降(jiang)解廢(fei)氣(qi)中(zhong)的污染物(wu)(wu)(wu)(wu)(wu)。

此生物(wu)膜一方(fang)面以廢氣中(zhong)的污染物(wu)為(wei)養料(liao)，進行生長繁殖;另一方(fang)面將廢氣中(zhong)的有毒(du)、有害惡臭物(wu)質分解，降解成無害的CO2，H2O,H2SO4，HNO3等簡單無機物(wu)，從(cong)而達到(dao)除(chu)臭的目的。
