PolyDADMAC monga organic coagulant ndi flocculant: chida champhamvu chochizira madzi otayira m'mafakitale

Chifukwa cha kukula kwa mafakitale mwachangu, kutuluka kwa madzi otayira m'mafakitale kwawonjezeka chaka ndi chaka, zomwe zikuika pachiwopsezo chachikulu ku chilengedwe. Pofuna kuteteza chilengedwe, tiyenera kutenga njira zogwirira ntchito pochiza madzi otayirawa. Monga munthu wodziyimira pawokha,cholumikizira chachilengedwe, PolyDADMAC pang'onopang'ono ikukhala njira yabwino kwambiri yothetsera madzi otayira m'mafakitale.

N’chifukwa chiyani tiyenera kuyeretsa madzi otayira m’mafakitale?

Zoopsa za madzi otayidwa m'mafakitale sizinganyalanyazidwe. Madzi otayidwa ali ndi ayoni ambiri achitsulo cholemera, mankhwala owopsa, mafuta, ndi zina zotero. Zinthuzi ndi zovulaza kwambiri kwa zamoyo zam'madzi ndi anthu. Kutuluka kwa madzi otayidwa osakonzedwa kwa nthawi yayitali kumabweretsa kuipitsa madzi, kuwonongeka kwa chilengedwe, komanso matenda a anthu.

Chifukwa cha kukula kosalekeza kwa kupanga mafakitale, madzi ambiri otayidwa amatulutsidwa mwachindunji m'chilengedwe popanda kukonzedwa, zomwe zimawononga kwambiri chilengedwe komanso kuopseza thanzi la anthu. Chifukwa chake, tiyenera kuchitapo kanthu pokonza madzi otayidwa m'mafakitale kuti tichepetse zotsatira zake zoyipa pa chilengedwe.

Chifukwa chiyani mungasankhePolyDADMACkuyeretsa madzi otayidwa m'mafakitale?

Pofuna kuthana ndi zoopsa za madzi otayidwa m'mafakitale, njira zochizira zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo kugawa alum kapena PAC. Komabe, njira zachikhalidwezi nthawi zambiri zimakhala ndi mavuto monga kuchuluka kwa matope, ntchito zovuta, komanso ndalama zambiri. Chifukwa chake, tifunika kupeza njira yochizira yogwira ntchito bwino, yotsika mtengo, komanso yosawononga chilengedwe. Monga chogwirizira chachilengedwe, PolyDADMAC ili ndi mphamvu zabwino kwambiri zozungulira ndi kutseka ndipo imatha kuchotsa mwachangu komanso moyenera zinthu zolimba zomwe zimayimitsidwa (nthawi zambiri zimakhala ndi ma ayoni achitsulo cholemera ndi mankhwala owopsa) m'madzi otayidwa. Poyerekeza ndi njira zachikhalidwe zochizira, PolyDADMAC ili ndi ubwino wosavuta kugwiritsa ntchito, kugwira ntchito bwino kwambiri, kuchuluka kwa matope ochepa, komanso mtengo wotsika. PolyDADMAC imagwiritsidwanso ntchito ngati chochotsera madzi otayidwa kuti achepetse kuchuluka kwa madzi otayidwa omwe amayambitsidwa ndi njira zina zamafakitale.

Kodi PolyDADMAC imagwira ntchito bwanji ndi madzi otayira m'mafakitale?

Choyamba, onjezerani yankho lochepetsedwa la PolyDADMAC ku madzi otayidwa muyeso winawake ndikusakaniza bwino powasakaniza. Pogwiritsa ntchito coagulant, zinthu zolimba zomwe zimapachikidwa m'madzi otayidwa zimasonkhana mwachangu ndikupanga tinthu tating'onoting'ono tating'onoting'ono. Kenako, kudzera mu njira zochiritsira monga sedimentation kapena sefa, floc imalekanitsidwa ndi madzi otayidwa kuti ikwaniritse cholinga choyeretsa madzi otayidwa.

Mukamagwiritsa ntchito PolyDADMAC pochiza madzi otayidwa m'mafakitale, muyenera kusamala ndi zinthu zotsatirazi. Choyamba, muyenera kusankha wogulitsa wabwino kwambiri kuti muwonetsetse kuti coagulant yomwe mwagulayo ndi yabwino kwambiri. Kachiwiri, malinga ndi mtundu ndi kuchuluka kwa madzi otayidwa, mlingo wa coagulant uyenera kusankhidwa moyenera kuti mupewe kumwa mankhwala ochulukirapo kapena kusakwanira kwa chithandizo chomwe chingapangitse kuti pasakhale zotsatira zabwino pa chithandizo. Nthawi yomweyo, ubwino wa madzi otayidwa okonzedwa uyenera kuyang'aniridwa nthawi zonse kuti zitsimikizire kuti miyezo yotulutsira madzi yakwaniritsidwa. Kuphatikiza apo, ogwira ntchito ayenera kulandira maphunziro aukadaulo ndikudziwa bwino mawonekedwe ndi kagwiritsidwe ntchito ka coagulant ndi njira zodzitetezera kuti atsimikizire chitetezo ndi kukhazikika kwa njira yochizira.

Mwachidule, PolyDADMAC, monga chogwirira ntchito chachilengedwe chogwira ntchito bwino komanso chotsika mtengo, ili ndi ubwino waukulu pochiza madzi otayidwa m'mafakitale. Pogwiritsa ntchito bwino PolyDADMAC, titha kuchepetsa bwino kuwonongeka kwa madzi otayidwa m'mafakitale ku chilengedwe ndikuteteza chilengedwe ndi thanzi la anthu. M'tsogolomu, ndi kupititsa patsogolo chidziwitso cha chilengedwe komanso kupita patsogolo kwaukadaulo, PolyDADMAC idzakhala ndi gawo lofunika kwambiri pantchito yosamalira madzi otayidwa m'mafakitale.
