大(da)氣(qi)污(wu)染(ran)是(shi)全球目前(qian)最突出的(de)(de)(de)環境(jing)問(wen)題之一(yi)，其污(wu)染(ran)物(wu)的(de)(de)(de)主要(yao)來源是(shi)工(gong)業(ye)廢(fei)氣(qi)，工(gong)業(ye)廢(fei)氣(qi)由于(yu)生(sheng)產的(de)(de)(de)工(gong)藝(yi)不(bu)同(tong)(tong)(tong)，產生(sheng)的(de)(de)(de)污(wu)染(ran)物(wu)種(zhong)類不(bu)同(tong)(tong)(tong)，不(bu)同(tong)(tong)(tong)污(wu)染(ran)物(wu)種(zhong)類應采用不(bu)同(tong)(tong)(tong)的(de)(de)(de)處理工(gong)藝(yi)。

1、油煙(yan)除塵廢氣治理

1）主(zhu)(zhu)要來源(yuan)：工(gong)業(ye)生產(chan)(chan)中會產(chan)(chan)生各(ge)種(zhong)(zhong)有機(ji)物廢(fei)(fei)氣(qi)(qi)(qi)(qi)，主(zhu)(zhu)要包括各(ge)種(zhong)(zhong)烴類、醇類、醛類、酸類、酮類和胺類等。這(zhe)些(xie)(xie)廢(fei)(fei)氣(qi)(qi)(qi)(qi)的(de)來源(yuan)十分廣泛(fan)，其中一(yi)些(xie)(xie)化(hua)學行(xing)業(ye) 石化(hua)、有機(ji)合成反應設(she)備排(pai)氣(qi)(qi)(qi)(qi)，印刷行(xing)業(ye)印墨(mo)中有機(ji)溶劑，機(ji)械行(xing)業(ye)機(ji)械噴(pen)漆(qi)，金屬制品產(chan)(chan)生的(de)氣(qi)(qi)(qi)(qi)味，汽(qi)車行(xing)業(ye)汽(qi)車的(de)噴(pen)漆(qi)、干燥爐鑄件生產(chan)(chan)設(she)備排(pai)氣(qi)(qi)(qi)(qi)，五金、家(jia)私廠噴(pen)涂(tu)設(she)備排(pai)氣(qi)(qi)(qi)(qi)等。 

2）有(you)機(ji)廢氣(qi)的危(wei)害：在生產中(zhong),有(you)機(ji)廢氣(qi)的排放一直是(shi)一個很突出的問題(ti)，絕大(da)多數有(you)機(ji)廢氣(qi)對人(ren)(ren)體的健(jian)康都(dou)有(you)害。如有(you)機(ji)廢氣(qi)通過(guo)呼吸(xi)道和皮膚進入人(ren)(ren)體后,能給人(ren)(ren)的呼吸(xi)、血液、肝臟(zang)等系統和器(qi)官(guan)造成暫時(shi)性和yong久性病變,尤其是(shi)苯并芘類多環(huan)芳烴能使人(ren)(ren)體直接致癌,危(wei)害人(ren)(ren)體健(jian)康。 

有(you)(you)機(ji)廢氣還(huan)會造成嚴重(zhong)的大(da)氣污(wu)染。一(yi)些有(you)(you)機(ji)物(wu)進入(ru)大(da)氣后(hou)，在一(yi)定條件下形成光化學煙霧，造成二(er)次污(wu)染；一(yi)些有(you)(you)機(ji)物(wu)進入(ru)平(ping)流(liu)層后(hou)，在紫外線的照射下與臭(chou)氧發生光化學反應，造成臭(chou)氧層空洞；一(yi)些有(you)(you)機(ji)物(wu)具有(you)(you)惡(e)臭(chou)污(wu)染和有(you)(you)害氣體的兩重(zhong)性；還(huan)有(you)(you)一(yi)些有(you)(you)機(ji)物(wu)會引起(qi)溫室效(xiao)應。 

3）廢氣(qi)治理方法： 

a.水膜除(chu)塵 活性碳吸附法； 

b.干式(shi)過濾除(chu)塵(chen) 活性碳吸附法 

c.活性碳(tan)吸附(fu) 催化燃燒法；
