Aluminium chlorohydrate (ACH) thiab polyaluminum chloride (PAC) zoo li yog ob hom tshuaj sib txawv uas siv los uacov flocculants hauv kev kho dejQhov tseeb, ACH yog cov khoom siv uas muaj zog tshaj plaws hauv tsev neeg PAC, xa cov alumina thiab basicity siab tshaj plaws uas ua tau hauv cov khoom khov lossis cov tshuaj khov kho. Ob qho tib si muaj kev ua tau zoo sib txawv me ntsis, tab sis lawv cov chaw siv sib txawv heev. Tsab xov xwm no yuav muab kev nkag siab tob txog ACH thiab PAC rau koj kom koj tuaj yeem xaiv cov khoom zoo.
Polyaluminum chloride (PAC) yog ib hom polymer molecular siab nrog cov mis tshuaj dav dav [Al2(OH)nCl6-n]m. Vim nws cov khoom siv tshuaj tshwj xeeb, nws muaj ntau yam kev siv hauv ntau qhov chaw. Polyaluminum chloride (PAC) ua lub luag haujlwm tseem ceeb hauv kev kho dej, tshem tawm cov khoom khov kho, cov tshuaj colloidal, thiab cov organic tsis yaj los ntawm cov txheej txheem coagulation. Los ntawm kev ua kom cov khoom me me tsis sib xyaw, PAC txhawb kev sib sau ua ke, pab txhawb lawv tshem tawm ntawm dej. PAC, feem ntau siv nrog rau lwm cov tshuaj xws li PAM, txhim kho cov dej zoo, txo qhov turbidity, thiab ua tau raws li cov qauv kev lag luam.
Hauv kev lag luam ua ntawv, PAC ua haujlwm ua cov flocculant thiab precipitant uas pheej yig, txhim kho kev kho dej phwj tuaj thiab kev ntsuas rosin-neutral. Nws txhim kho cov teebmeem ntsuas, tiv thaiv cov ntaub thiab lub kaw lus ua qias tuaj.
Cov kev siv PAC nthuav dav mus rau kev lag luam mining, pab ntxuav cov hlau thiab cais cov hlau. Nws cais cov dej ntawm cov hlau, ua kom yooj yim rau kev siv dua, thiab ua kom cov sludge qhuav.
Hauv kev rho tawm roj av thiab kev ua kom huv, PAC tshem tawm cov khoom tsis huv, cov organic uas tsis yaj, thiab cov hlau los ntawm cov dej khib nyiab. Nws ua rau cov roj poob thiab tshem tawm cov roj poob, ua kom cov qhov dej ruaj khov thiab tiv thaiv kev puas tsuaj thaum lub sijhawm khawb roj.
Kev luam ntawv thiab zas xim ntaub tau txais txiaj ntsig los ntawm PAC lub peev xwm los kho cov dej khib nyiab uas muaj ntau thiab muaj cov organic pollutants ntau. PAC txhawb kom cov paj alum khov kho sai, ua tiav cov txiaj ntsig zoo kawg nkaus.
ACH, Aluminium Chlorohydrate, nrog rau cov mis molecular Al2(OH)5Cl·2H2O, yog ib qho inorganic polymer compound uas muaj qib alkalization siab dua piv rau polyaluminum chloride thiab tsuas yog aluminium hydroxide xwb. Nws dhau los ntawm kev sib txuas polymerization los ntawm hydroxyl pawg, ua rau lub molecule muaj cov pawg hydroxyl ntau tshaj plaws.
Muaj nyob rau hauv kev kho dej thiab txhua hnub-tshuaj qib (khoom siv niaj hnub), ACH los ua hmoov (khoom) thiab kua (kua), nrog rau cov khoom ua ib tug hmoov dawb thiab cov tshuaj ib tug xim pob tshab kua.
Cov khoom tsis yaj thiab Fe cov ntsiab lus tsawg, yog li nws tuaj yeem siv rau hauv cov tshuaj lom neeg txhua hnub.
ACH pom ntau yam kev siv. Nws ua haujlwm ua cov khoom siv raw rau cov tshuaj thiab cov tshuaj pleev ib ce tshwj xeeb, tshwj xeeb tshaj yog cov khoom xyaw tseem ceeb ntawm cov tshuaj tiv thaiv hws uas paub txog nws qhov ua tau zoo, tsis khaus, thiab kev nyab xeeb. Tsis tas li ntawd, ACH kim heev thiab yog li ntawd tsis tshua siv ua flocculant hauv dej haus thiab kev kho dej khib nyiab hauv kev lag luam. ACH kuj qhia tau tias muaj kev sib xyaw ua ke zoo dua li cov ntsev hlau ib txwm muaj thiab cov tshuaj polyaluminum chlorides qis.
