Chifukwa chiyani mpweya wopangidwa umagwira ntchito yofunika kwambiri pakuchiza madzi

Kusinthasintha kwa mpweya wopangidwa ndi activated carbon kuli kopanda malire, ndipo ntchito zoposa 1,000 zodziwika zikugwiritsidwa ntchito. Kuyambira migodi ya golide mpaka kuyeretsa madzi, kupanga zakudya ndi zina zambiri, mpweya wopangidwa ndi activated carbon ukhoza kusinthidwa kuti ukwaniritse zosowa zosiyanasiyana.

Ma carbon opangidwa ndi mpweya amapangidwa kuchokera ku zinthu zosiyanasiyana zochokera ku carbon - kuphatikizapo zipolopolo za kokonati, peat, matabwa olimba ndi ofewa, malasha a lignite ndi dzenje la azitona kungotchula zochepa chabe. Komabe, zinthu zilizonse zachilengedwe zokhala ndi carbon yambiri zingagwiritsidwe ntchito bwino popanga ma carbon opangidwa ndi mpweya kudzera mu kusintha kwa thupi ndi kuwonongeka kwa kutentha.

Kugwiritsa ntchito kwambiri mpweya wopangidwa ndi activated carbon masiku ano kumakhudza kwambiri njira zochizira madzi ogwiritsidwa ntchito, madzi otayidwa m'mafakitale ndi m'mabizinesi komanso mavuto ochepetsa mpweya/fungo. Zinthu zoyambira mpweya zikasinthidwa kukhala mpweya wopangidwa ndi activated carbon, zimatha kuyeretsa bwino ndikuchotsa zinthu zambiri zodetsa m'madzi ndi m'mitsinje ya madzi otayidwa.

Udindo waukulu wa mpweya woyatsidwa pa kuchiza madzi (imodzi mwa mankhwala ochiza madzi)

Ma carbon opangidwa ndi mphamvu amapereka njira imodzi yothandiza kwambiri yochotsera zinthu zodetsa monga THM ndi DBP komanso kuchotsa zinthu zachilengedwe ndi mankhwala ophera tizilombo m'madzi. Izi sizimangowonjezera kukoma komanso kuchepetsa zoopsa paumoyo komanso zimateteza zida zina zoyeretsera madzi monga reverse osmosis membranes ndi ma ion exchange resins ku kuwonongeka komwe kungachitike chifukwa cha okosijeni kapena kuipitsidwa ndi organic.

Kaboni yoyatsidwa ikadali imodzi mwa njira zochizira madzi zomwe zimakondedwa kwambiri ku UK ndi Ireland chifukwa cha ntchito zake zodabwitsa komanso ntchito zake zosiyanasiyana.

Mitundu ya ma carbon opangidwa

Mpweya wopangidwa ndi activated nthawi zambiri umagwiritsidwa ntchito pochiza madzi m'njira ziwiri zosiyana kwambiri - ma carbon opangidwa ndi ufa (PAC) ndi ma granular activated carbon (GAC). Komabe, njira zogwiritsira ntchito ndi momwe amagwiritsidwira ntchito pa mtundu uliwonse wa ma carbon opangidwa ndi activated zimasiyana kwambiri. Kusankha mtundu winawake wa ma carbon opangidwa ndi activated kuti agwiritsidwe ntchito m'madzi kudzadalira mtundu wa ntchito yeniyeniyo, zotsatira zomwe zikufunika komanso zoletsa zilizonse zomwe zikuchitika.

Ma carbon opangidwa ndi ufa amagwiritsidwa ntchito ndi mafakitale oyeretsera madzi kuti achepetse kukoma ndi fungo komanso kuonetsetsa kuti mankhwala achilengedwe achotsedwa. Ma PAC amawonjezedwa koyambirira kwa njira yoyeretsera kuti athe kukhala ndi nthawi yolumikizana yokha mankhwala ena oyeretsera asanawonjezedwe kumtsinje wamadzi.

Siziyenera kupakidwa mankhwala ena aliwonse ochizira madzi asanayambe kupatsidwa nthawi yokwanira yokhudzana ndi madzi (nthawi zambiri ma PAC amafunika mphindi zosachepera 15 kuti agwirizane ndi madzi okha). Chofunika kwambiri, PAC sayenera kuwonjezeredwa nthawi imodzi ndi chlorine kapena potassium permanganate chifukwa mankhwala ochizira madzi amenewa amangotengedwa ndi ufa wa carbon womwe umayambitsidwa.

Mlingo wofunikira nthawi zambiri ungakhale pakati pa 1 mpaka 100 mg/L kutengera mtundu ndi kuchuluka kwa chodetsa, koma mlingo wa 1 mpaka 20 mg/L ndi wofala kwambiri pokonza mitsinje yamadzi kuti achepetse kukoma ndi fungo. Mlingo wokwera udzafunika pamene ma PAC awonjezedwa pambuyo pake mu njira yochizira, kuti mankhwala ena ochizira alowetsedwe kale mu njira yochizira. Ma PAC amachotsedwa pambuyo pake mu mitsinje yamadzi kudzera mu njira yothira madzi kapena kudzera m'mabedi osefera.

Hebei medipharm co., Ltd ndi kampani yotsogola yogulitsa mpweya wochita kukonzedwa. Timapereka mitundu yosiyanasiyana ya ufa wa mpweya wochita kukonzedwa komanso ma granule a mpweya wochita kukonzedwa pamsika. Ngati mukufuna zambiri za mitundu yathu ya mpweya wochita kukonzedwa kapena muli ndi funso loti gulu lathu la akatswiri lifunseni, chonde titumizireni uthenga.
