Mokhoa oa ho sebelisa likhemik'hale tsa kalafo ea metsi 1

Hona joale re ela hloko ho feta ho phekola metsi a litšila ha tšilafalo ea tikoloho e ntse e mpefala. Lik'hemik'hale tsa kalafo ea metsi ke lithuso tse hlokahalang bakeng sa lisebelisoa tsa kalafo ea likhoerekhoere. Mona re hlahisa mekhoa e sebelisang lik'hemik'hale tse fapaneng tsa kalafo ea metsi.

I.Polyacrylamide sebelisa mokhoa: (Bakeng sa indasteri, masela, likhoerekhoere tsa masepala joalo joalo)

Hlapolla sehlahisoa e le tharollo ea 0,1% -0,3%. Ho molemo ho sebelisa metsi a sa jeleng paate ntle le letsoai ha o hlapolla (joalo ka metsi a pompo)

Ka kopo hlokomela: Ha u hlapolla sehlahisoa, ka kopo laola sekhahla sa phallo ea mochini oa dosing ka bohona, ho qoba ho kopana, boemo ba tlhapi le ho koala lipeipi.

3.Ho susumetsa e lokela ho ba metsotso e fetang 60 ka li-roll tsa 200-400 / min.Ke betere ho laola mocheso oa metsi joalo ka 20-30 ℃, e tla potlakisa ho senyeha, empa ka kopo etsa bonnete ba hore mocheso o ka tlase ho 60 ℃.

4.Ka lebaka la ph e mengata e fapaneng eo sehlahisoa sena se ka ikamahanyang le eona, litekanyetso li ka ba 0.1-10 ppm, e ka fetoloa ho latela boleng ba metsi.

Mokhoa oa ho sebelisa moholi coagulant: (Lik'hemik'hale tse sebelisetsoang kalafo ea likhoerekhoere haholo)

1. Ts'ebetsong ea ho penta, ka kakaretso eketsa moholi oa pente coagulant A hoseng, ebe o fafatsa pente ka mokhoa o tloaelehileng. Qetellong, eketsa moholi oa pente coagulant B halofo ea hora pele o tsoa mosebetsing.

2. Ntlha ea ho lekanya ea moholi oa pente e koaletsoeng Moemeli o le lesobeng la metsi a potolohang, 'me ntlha ea moemeli ea moemeli oa B e sebakeng sa metsi a potolohang.

3. Ho latela palo ea pente ea ho fafatsa le bongata ba metsi a potolohang, fetola palo ea moholi oa pente coagulant A le B ka nako.

4. Ho lekanya boleng ba PH ba metsi a potolohang khafetsa habeli ka letsatsi ho a boloka a le lipakeng tsa 7.5-8.5, moemeli ona a ka bang le phello e ntle.

5. Ha metsi a potolohang a sebelisoa nako e itseng, conductivity, boleng ba SS le lintho tse tiileng tse emisitsoeng tsa metsi a potolohang li tla feta boleng bo itseng, bo tla etsa hore moemeli enoa a be thata ho qhibiliha metsing a potolohang mme ka hona a ame phello ea moemeli enoa. Ho kgothaletswa ho hloekisa tanka ea metsi le ho nkela metsi a potolohang pele o sebelisoa. Nako ea phetoho ea metsi e amana le mofuta oa pente, boholo ba pente, boemo ba leholimo le maemo a ikhethileng a thepa ea ho roala, 'me e lokela ho kengoa tšebetsong ho latela likhothaletso tsa setsebi sa setsing.
