Polyaluminium chloride yog cov dej-soluble inorganic polymer coagulant. Vim tias qhov cuam tshuam ntawm hydroxide ions thiab cov polymerization ntawm polyanions, nws yog ib qho inorganic polymer dej kho tus neeg sawv cev nrog loj molecular hnyav thiab ntau dua. Qhov ntau npaum ntawm polyaluminium chloride tus neeg sawv cev yog 3-40 g / ton rau cov khoom ua kua thiab 1-15 g / ton rau cov khoom lag luam, uas yog txiav txim los ntawm tus neeg siv raws li kev sib xyaw ua ke thiab kev sim ntau lawm.
Raws li cov xwm txheej sib txawv ntawm cov dej nyoos, koj tuaj yeem ua qhov ntsuas me me kom pom qhov zoo tshaj plaws ua ntej siv polyaluminium. Txhawm rau ua kom yooj yim rau kev suav, cov tshuaj ntsuam me me tau teeb tsa raws li qhov loj-ntim piv (M / V), feem ntau 1% yog qhov zoo dua. Yog tias npaj 1% kev daws teeb meem: hnyav PAC1g, muab tso rau hauv lub tog raj kheej ntxuav 100ml, ntxiv dej rau dilute rau 100 cim tom qab nws yaj, thiab co nws zoo. Yog tias nws siv hauv kev tsim khoom, ua ntej sib tov thiab yaj cov khoom nrog dej huv, ces ntxiv dej kom dilute mus rau qhov xav tau concentration. Cov kua tuaj yeem diluted ncaj qha raws li qhov xav tau concentration.
Nws yuav tsum raug sau tseg tias cov tshuaj kho dej ntawm cov tuam txhab sib txawv lossis cov npe sib txawv tsis tuaj yeem sib xyaw, thiab yuav tsum tsis txhob sib xyaw nrog lwm cov tshuaj; thawj cov tshuaj thiab diluent yog me ntsis corrosive, tab sis qis dua lwm yam inorganic coagulants; Cov khoom lag luam tau khaws cia zoo Lub Sijhawm: ib nrab xyoo rau cov kua thiab ib xyoos rau khoom. Cov khoom lag luam tseem tuaj yeem siv tom qab ntub dej. Kev siv cov txheej txheem ntawm polyaluminium ferric chloride, polyferric sulfate thiab polyaluminium zoo ib yam, thiab cov kev siv tshwj xeeb yog txiav txim siab los ntawm qhov zoo ntawm cov dej los kho.
