大(da)氣(qi)污染(ran)是全球目前(qian)最(zui)突出(chu)的環境問(wen)題之一，其污染(ran)物的主(zhu)要(yao)來(lai)源是工(gong)業(ye)廢氣(qi)，工(gong)業(ye)廢氣(qi)由(you)于生(sheng)產的工(gong)藝不(bu)同(tong)(tong)(tong)，產生(sheng)的污染(ran)物種類不(bu)同(tong)(tong)(tong)，不(bu)同(tong)(tong)(tong)污染(ran)物種類應(ying)采用(yong)不(bu)同(tong)(tong)(tong)的處(chu)理工(gong)藝。

1、油(you)煙除塵廢氣治理

1）主要來(lai)源：工(gong)業生(sheng)(sheng)產(chan)中(zhong)(zhong)會產(chan)生(sheng)(sheng)各種有機(ji)(ji)物廢氣(qi)(qi)，主要包(bao)括(kuo)各種烴類(lei)(lei)(lei)、醇類(lei)(lei)(lei)、醛類(lei)(lei)(lei)、酸類(lei)(lei)(lei)、酮類(lei)(lei)(lei)和胺類(lei)(lei)(lei)等。這(zhe)些廢氣(qi)(qi)的來(lai)源十分廣泛，其中(zhong)(zhong)一些化(hua)學行(xing)業 石化(hua)、有機(ji)(ji)合成(cheng)反應(ying)設備(bei)排氣(qi)(qi)，印刷行(xing)業印墨中(zhong)(zhong)有機(ji)(ji)溶(rong)劑(ji)，機(ji)(ji)械行(xing)業機(ji)(ji)械噴(pen)漆，金屬制品(pin)產(chan)生(sheng)(sheng)的氣(qi)(qi)味，汽車(che)行(xing)業汽車(che)的噴(pen)漆、干燥(zao)爐(lu)鑄件(jian)生(sheng)(sheng)產(chan)設備(bei)排氣(qi)(qi)，五金、家私廠(chang)噴(pen)涂(tu)設備(bei)排氣(qi)(qi)等。 

2）有(you)機廢氣的危害：在生產中,有(you)機廢氣的排放(fang)一直(zhi)是一個很(hen)突(tu)出的問(wen)題(ti)，絕(jue)大多數有(you)機廢氣對人(ren)體的健康都有(you)害。如有(you)機廢氣通過呼吸(xi)道和皮膚(fu)進入(ru)人(ren)體后,能(neng)給人(ren)的呼吸(xi)、血液、肝臟等系統和器官造成暫時(shi)性和yong久性病變,尤(you)其(qi)是苯并芘類(lei)多環芳(fang)烴(jing)能(neng)使人(ren)體直(zhi)接致癌,危害人(ren)體健康。 

有(you)(you)機(ji)廢氣還會(hui)造(zao)(zao)成嚴(yan)重的大氣污(wu)染(ran)。一(yi)些(xie)(xie)有(you)(you)機(ji)物進入(ru)大氣后，在一(yi)定條件(jian)下形成光(guang)化學煙(yan)霧(wu)，造(zao)(zao)成二次污(wu)染(ran)；一(yi)些(xie)(xie)有(you)(you)機(ji)物進入(ru)平流層后，在紫外線(xian)的照射下與臭(chou)氧發生光(guang)化學反應，造(zao)(zao)成臭(chou)氧層空洞(dong)；一(yi)些(xie)(xie)有(you)(you)機(ji)物具(ju)有(you)(you)惡臭(chou)污(wu)染(ran)和有(you)(you)害氣體的兩重性(xing)；還有(you)(you)一(yi)些(xie)(xie)有(you)(you)機(ji)物會(hui)引(yin)起溫室(shi)效(xiao)應。 

3）廢氣治理方法： 

a.水(shui)膜(mo)除塵(chen) 活性碳吸附(fu)法； 

b.干(gan)式過(guo)濾(lv)除塵 活性碳吸附法 

c.活性碳吸附 催化燃燒法；
