大氣(qi)污(wu)(wu)染(ran)是(shi)全球(qiu)目前最突出的環境問題之一，其(qi)污(wu)(wu)染(ran)物(wu)的主要(yao)來源是(shi)工(gong)(gong)業廢氣(qi)，工(gong)(gong)業廢氣(qi)由于(yu)生產的工(gong)(gong)藝不(bu)同(tong)(tong)，產生的污(wu)(wu)染(ran)物(wu)種類(lei)不(bu)同(tong)(tong)，不(bu)同(tong)(tong)污(wu)(wu)染(ran)物(wu)種類(lei)應采用不(bu)同(tong)(tong)的處理工(gong)(gong)藝。

1、油煙除塵廢氣(qi)治理

1）主要來(lai)源：工業(ye)(ye)生產(chan)(chan)中(zhong)會產(chan)(chan)生各(ge)種(zhong)有(you)機物廢氣(qi)(qi)(qi)，主要包括各(ge)種(zhong)烴類、醇類、醛類、酸(suan)類、酮類和(he)胺(an)類等(deng)。這些廢氣(qi)(qi)(qi)的(de)來(lai)源十(shi)分廣泛，其中(zhong)一些化學行(xing)(xing)(xing)(xing)業(ye)(ye) 石化、有(you)機合成反應設備(bei)(bei)排(pai)氣(qi)(qi)(qi)，印刷行(xing)(xing)(xing)(xing)業(ye)(ye)印墨中(zhong)有(you)機溶劑，機械(xie)行(xing)(xing)(xing)(xing)業(ye)(ye)機械(xie)噴漆，金(jin)屬制品產(chan)(chan)生的(de)氣(qi)(qi)(qi)味，汽(qi)(qi)車(che)行(xing)(xing)(xing)(xing)業(ye)(ye)汽(qi)(qi)車(che)的(de)噴漆、干燥爐(lu)鑄件生產(chan)(chan)設備(bei)(bei)排(pai)氣(qi)(qi)(qi)，五金(jin)、家(jia)私廠噴涂(tu)設備(bei)(bei)排(pai)氣(qi)(qi)(qi)等(deng)。 

2）有(you)(you)機(ji)廢氣(qi)(qi)的(de)危害：在生(sheng)產中(zhong),有(you)(you)機(ji)廢氣(qi)(qi)的(de)排放一直是一個很突出(chu)的(de)問題(ti)，絕大多數有(you)(you)機(ji)廢氣(qi)(qi)對人體的(de)健康都有(you)(you)害。如有(you)(you)機(ji)廢氣(qi)(qi)通過呼(hu)吸道和(he)皮(pi)膚進(jin)入人體后,能(neng)給人的(de)呼(hu)吸、血液、肝(gan)臟等系統和(he)器官造成暫時性和(he)yong久性病變,尤其(qi)是苯并(bing)芘(bi)類多環芳烴能(neng)使(shi)人體直接致(zhi)癌,危害人體健康。 

有(you)機(ji)(ji)廢氣還會(hui)造(zao)成(cheng)(cheng)嚴重(zhong)(zhong)的(de)大氣污(wu)(wu)染。一(yi)(yi)些(xie)有(you)機(ji)(ji)物(wu)進入大氣后，在一(yi)(yi)定(ding)條件(jian)下形成(cheng)(cheng)光(guang)化學煙(yan)霧，造(zao)成(cheng)(cheng)二(er)次污(wu)(wu)染；一(yi)(yi)些(xie)有(you)機(ji)(ji)物(wu)進入平流(liu)層(ceng)后，在紫(zi)外線的(de)照(zhao)射下與臭(chou)(chou)氧發生光(guang)化學反應，造(zao)成(cheng)(cheng)臭(chou)(chou)氧層(ceng)空(kong)洞；一(yi)(yi)些(xie)有(you)機(ji)(ji)物(wu)具有(you)惡臭(chou)(chou)污(wu)(wu)染和有(you)害氣體的(de)兩重(zhong)(zhong)性；還有(you)一(yi)(yi)些(xie)有(you)機(ji)(ji)物(wu)會(hui)引起溫室效應。 

3）廢氣(qi)治理方(fang)法： 

a.水膜除塵 活(huo)性碳吸附法； 

b.干式過濾除塵(chen) 活性碳吸附(fu)法(fa) 

c.活性碳吸附 催化燃燒(shao)法；
