Ngā Kaihoroi: Te Kōwhiringa, Te Mahi, me Ngā Āhuatanga
Ko te whai huatanga o te tukatuka hau para VOC e whakawhirinaki ana ki te whiriwhiri rautaki me te whakatinanatanga o ngā adsorbents i hangaia hei hopu i te whānuitanga o ngā matū waro pūngāwerewere i raro i ngā āhuatanga uaua o te tukanga whakarewa. He maha ngā paearu matua e whakatau ana i te whiriwhiri me te whai huatanga o ngā rauemi adsorbents i roto i ēnei tautuhinga.
Ka tīmata te kōwhiringa mā te kaha mimiti, he ine i te nui o te VOC ka taea e te rauemi te hopu i mua i te taenga ki te mākū. Ka whakaitihia e ngā mimiti kaha-teitei ngā aukati tiaki me te mahi, ka tautoko i ngā pūnaha maimoatanga hau para VOC ahumahi pumau. He mea nui anō hoki te whiriwhiri—me hopu pakari ngā rauemi i ngā VOC whainga me te kore e pokanoa mai i ngā poke tahi e kitea ana i roto i ngā hau paru whakarewa, pērā i ngā paoa whakarewa, i ngā matūriki rānei. Mā te tere o te mimiti me te mimiti ka taea te urupare tere ki ngā punga tukunga me te whakaora pai o te mimiti, he mea nui hei pupuri i te whai huatanga o te maimoatanga me te whakaiti i ngā utu whakahaere. I te mea he maha ngā wā ka puta ngā tukunga whakarewa i ngā pāmahana teitei me ngā āhuarangi waikura pea, ka pā tika te ātete o te mimiti ki te pirau wera me te matū ki tōna roanga ora me te pono o te tukanga.
Ko te pūngao me te horahanga o te mata te mea e tautuhi ana i ngā āhuatanga o te rauemi. E mōhiotia ana ngā waro whakahohe mō te tino teitei o ngā horahanga o te mata me te pūngao iti, e tuku ana i te mahi kaha i roto i te hangarau mimiti VOC ahumahi me ngā tikanga whakahaere parahanga hau VOC. Ko ngā zeolite, me ō rātou pūngao iti ōrite me te hanganga tioata, ka whakarato i te mimiti whiriwhiri me te pumau ki te wera, e pai ake ana ki te tango i ngā momo VOC motuhake. Ko ngā anga whakarewa-ora (MOF) e whakaatu ana i ngā rahi pūngao me ngā mahi matū ka taea te whakarite, e taea ai te arotahi tika ki ngā ngota VOC. Heoi, kei te puta tonu te whakamahinga arumoni, ā, he nui ake ngā utu tīmatanga i ngā rauemi tuku iho.
Ko te whai huatanga o te utu te mea nui hei whakaaroaro. Kei te pai tonu te mimiti waro whakahohe mō ngā VOC nā te mea kei te wātea i te mākete, he iti te utu, ā, he pai hoki te hopu VOC totoka. Heoi anō, ka heke pea tōna mahi i ngā pāmahana teitei e kitea ana i roto i ngā oumu whakarewa mēnā kāore i hangaia mō te ātete wera. Ahakoa he nui ake te utu o te hanga i ngā zeolite, ka taea te whakakapi i te ātete wera, inā koa ka whakamahia i roto i ngā moenga mimiti pāmahana teitei. Ahakoa he pai te whakarerekētanga o ngā MOF, he maha ngā wā ka nui ake ngā utu rauemi me te tukatuka, ā, ko tō rātou pumau mō te wā roa i raro i te mahi ahumahi tonu te arotahi o te rangahau me te mahi hangarau i tēnei wā.
