Chifukwa chiyani zosefera mpweya zimagwiritsidwa ntchito kwambiri?

Pakadali pano, pali mabizinesi 2532 omwe amatulutsa zida zosefera mphete padziko lonse lapansi, ndipo kotala lawo adakhazikitsidwa zaka zisanu zapitazi. M'zaka zaposachedwa, khansa ya m'mapapo kwakhala ikukulira chifukwa cha zinthu monga kuipitsidwa kwa mpweya, malo osadzilamulira, komanso kukwera kosalekeza kwa anthu osuta. Kuda nkhawa kwa anthu ndi nkhawa za zoopsa zobisika zomwe zimachitika chifukwa cha kuwonongeka kwa chilengedwe kwadzetsa kuwonjezeka kosalekeza kwa chilengedwe pakati pa anthu onse. M'malo mwake, kupezeka kwa Haze nthawi zambiri kwadzetsanso kukula kwa makampani opanga mpweya pazaka zingapo zapitazi. Ndi kupita patsogolo kosalekeza kwaukadaulo wa mafakitale, kuwongolera kwa anthu komanso ukhondo wa mafakitale kumathandizanso nthawi zonse. Chifukwa chake, zosefera zamlengalenga zimagwiritsidwanso ntchito kawirikawiri pakupanga mafakitale. Tonse tikudziwa kuti pali fumbi lambiri lomwe limayimitsidwa mlengalenga, lomwe silingagwidwe ndi diso lamaliseche. Chifukwa chake, sitingathe kulimbana ndi fumbi lino kudzera njira zonse zotsukira, koma nthawi zambiri, fumbi limakhala likukhudzanso opaleshoni yawo. Mwachitsanzo, ngati fumbi mlengalenga limagwera mbali zoyendetsera makina a makina, zimathandizira kuvala mbali zosewerera, kuchepetsa chitsimikizo ndi moyo wa makinawo. Fumbi lofalikira mu msonkhano limatha kuchepetsa kuwoneka, kumakhudza masomphenya, kulepheretsa ntchito zowonjezera. Kugwiritsa ntchito zosefera kwa mpweya mu mafakitale kumatha kuyeretsa mpweya ndi fumbi lotsika ndikuwatumiza. Nthawi zambiri amagwiritsidwa ntchito m'makampani a microectronics, zojambulajambula, chakudya ndi chakumwa, makampani a biophormaceutical, ndi zina zambiri.

Cholinga cha zosefera mpweya ndikupeza mpweya wabwino womwe umakwaniritsa miyezo. Nthawi zambiri, osefera osefukira amapangidwa kuti agwire ndi adshorb fumbi la kukula kwina kwamlengalenga, kukonza mpweya. Zosefera zamankhwala sizimangokhala fumbi la Adsorb yokha komanso fungo.
Kuphatikiza apo, chifukwa chowonjezera chitetezo zachilengedwe pa mabizinesi, pali zofunika kwambiri pakuwonongeka kwa mpweya. Kuti atuluke otuluka m'mafakitale, zofunika moyenera ndi vuto. Zitsulo zina zolemera monga mercury zolemera, argenic, Chrymium, Beryllium, etc. ndi zowopsa ndipo zimapangitsa kuti mitundu yokhazikika. Pankhani ya mpweya woopsa, United States ndi Germany yadutsa malamulo atsopano ndi owuma. Pambuyo kukhazikitsa malamulo atsopano, malire pamtundu wa mpweya wachepetsedwa kuchokera ku 20mg / m3 (muyezo) mpaka 010004mg / m3 (mu 3). Kuti mukwaniritse cholingachi, fakitaleyo imafunikira zosefera kwambiri kuti muchotse tinthu tating'onoting'ono.
