Polyaluminium chloride (PAC) yog ib hom ntawm cov dej purification cov ntaub ntawv, inorganic polymer coagulant. Raws li nws daim ntawv, nws yuav tsum txwv kom muab zais li: khoom thiab kua daim ntawv. Cov khoom daim ntawv muaj cov daj los yog tsaus daj xim, tsaus xim av, tsaus ntuj nti grey cob zoo li xim. Cov kua hais raws li ib tug tsis muaj kob, pob tshab, me ntsis daj, lub teeb daj los xim av xim. PAC nyob rau hauv daim ntawv thov ntawm cov xim txawv thiab ntau lawm technology kuj muaj qhov sib txawv ib yam ntawm cov zoo heev dej purification, uas yog wildly siv nyob rau hauv lub purification ntawm cov dej haus, kev lag luam dej, kev lag luam kev dej thiab lub sij hawm thiab kuab dej los ntawm lub chaw muag tshuaj ua lag luam, daim ntawv ua kev lag luam thiab luam ntawv thiab tuag kev lag luam, raws li tau zoo raws li lub neej sij hawm dej.

PAC Hmoov Polyaluminium Chloride rau Kev tsav tsheb kiag Dej Kho Mob
Polyaluminum chloride yog ib tug dej purification khoom, ib tug inorganic polymer coagulant, thiab ib tug polymer nrog ib tug kuj loj molecular nyhav thiab ib tug siab kuj them nyiaj ntawm inorganic polymer ua los ntawm tus choj kev txiav txim ntawm hydroxyl ions thiab cov polymerization ntawm polyvalent anions. Tsev muag tshuaj. Nyob rau hauv daim ntawv, nws yuav tsum tau muab faib mus rau hauv ob hom: cov khoom thiab kua. Cov khib nyiab yog muab faib ua xim av, beige, golden daj thiab dawb raws li nyias xim, thiab cov kua uas muaj tuaj raws li tsis muaj kob, pob tshab, yellowish, lub teeb daj daj-xim av.
Lub polyaluminum chloride muaj ib tug cov ntsiab lus ntawm txhuas oxide ntawm 27 thiab 30 yog feem ntau khaki-daj daj khoom hmoov. Cov polyaluminum chlorides muaj kuj zoo dej solubility, thiab nyob rau hauv lub chav kawm ntawm xaus, physicochemical kev hloov xws li electrochemical, agglomeration, adsorption, thiab nag lossis daus nws thiaj li ua rau [Al2 (OH) 3 (OH) 3] nag lossis daus, li no tsis tau raws li lub hom phiaj ntawm purification. Nyob rau hauv qhov kev siv ntawm polyaluminum chloride, tsis muaj qhov yuav tsum tau rau lwm additives, floe tsim yog ceev thiab tuab, siab ua si, ceev ceev los nag, thiab ib cov ntshiab ntxim rau siab turbidity dej purification.
Cov raw khoom ntawm lub daj polyaluminum chloride yog calcium aluminate hmoov, hydrochloric acid, bauxite, mas siv rau dej kev kho mob thiab cov dej haus kev kho mob, yog hais tias tus raw khoom rau cov dej haus kev kho mob yog txhuas hydroxide hmoov, hydrochloric acid, thiab me ntsis calcium aluminate Hmoov, phaj thiab ncej siab pom dab los yog tshuaj tsuag kom qhuav dab muaj nruj uas yuav tsum tau nyob rau hauv hnyav hlau nyob rau hauv lub haus dej kev kho mob lub teb chaws, li ntawd, ob qho tib si raw cov ntaub ntawv thiab ntau lawm dab yog zoo dua tan PACS.
Cov raw cov ntaub ntawv rau lub tan txhuas polyaluminum chloride yog calcium aluminate hmoov, hydrochloric acid, bauxite thiab hlau hmoov. Nws yog tsuas yog siv rau dej kev kho mob vim hais tias nws muaj hlau hmoov li cov xim yog ziab tshav. Qhov ntau hlau hmoov yog ntxiv, ib tsos tsaus tsawv nws yog. Yog hais tias cov hlau hmoov tshaj ib qhov nqi, nws hu tej zaum ua polyaluminum chloride hlau. , Muaj zoo heev tau nyob rau hauv cov kev kho mob ntawm dej.
Concentration piv hom:
1. Raws li qhov teeb meem ntawm nyoos dej, ua ib tug me me kev kuaj ua ntej yuav siv tau rau kom tau qhov zoo tshaj plaws tshuaj. Me xeem cov tshuaj configuration by luj ratio (W / W), feem ntau 2-5% nrog zoo. Tuaj txoos ua ke nrog 3% kua: hais tias polyaluminum chloride PAC khoom 3g, mus rau hauv ib tug 200ml measuring lub tog raj kheej, ntxiv txog 50 ml ntawm dej, yuav tsum tau yaj thiab ces diluted nrog dej mus 100ml scale, co nws.
2. Thaum ua polyaluminum chloride PAC rau ntau lawm, sib tov thiab yaj raws li polyaluminum chloride PAC khoom: dej = 1: 9 mus rau 1:15 ceeb thawj piv. Solutions nrog ib tug cov ntsiab lus ntawm alumina tsawg tshaj li 1% yog cov nquag mus hydrolysis thiab yuav txo tau cov nyhuv ntawm kev siv. Ntau yog siab dhau heev lawm yuav tsum tau yooj yim ntxiv tusyees.
3. dosing raws li qhov zoo tshaj plaws dosing nqi tau los ntawm me me kev kuaj. Piv txwv li, yog tias sedimentation tso tsheb hlau luam muaj nyob rau yuav tsawg, yog tias muaj loj nyiaj ntawm turbidity, ntau npaum yuav heev me me. Yog hais tias lub sedimentation tank yog loj thiab upturned thiab tshuav turbidity yog high, tus nqi ntawm cov dosing yog loj heev thiab kev kho me ntsis yuav tsum tau ua.
Polyaluminium chloride siv txoj kev:
Tom qab cov khoom Cov khoom no yog yaj nyob rau hauv dej ntawm 1: 3, nws yog siv raws li ib tug ua kua, diluted nrog 10-30 lub sij hawm ntawm cov dej tshiab mus rau ib tug yam concentration. Lub pom PH nqi rau cov dosing yog 3.5-5.0, thiab qhov zoo tshaj plaws PH nqi yog ntxiv rau kom cov kev pab cuam ntawm coagulation. Cov tshuaj yuav tsum tau txiav txim raws li qhov sib txawv turbidity ntawm cov nqaij nyoos dej, thiab qhov zoo tshaj plaws tshuaj yog txiav txim. Thaum cov nqaij nyoos dej turbidity yog 100-500mg / L, ntau npaum ib kiloton yog 10-20kg. Thaum lub turbidity ntawm cov nqaij nyoos dej yog high, ntau npaum no tsim nyog nce, thiab thaum twg lub turbidity yog tsawg tsawg, ntau npaum yuav tsim nyog txo.
Cov tshuaj ntawm polyaluminum chloride nyob rau hauv txawv dej zoo:
Ua ntej, nyob rau hauv uas tsis muaj turbidity dej, cov khoom polyaluminum chloride khoom diluted 1: 3 (ceeb thawj piv) ntxiv coj mus rhaub dej thiab do kom txog thaum kiag yaj.
Ob, nyob rau hauv lub neej thiab ntau lawm siv dej, nrog reference rau txhua tuj ntawm dej ua ntej yuav muab hais txog 30g ntawm polyaluminum chloride khoom. Ces ntxiv diluted polyacrylamide product (yog hais tias tus nyhuv yog tsis cuab kev, thov kom tsis txhob los ua rau kom cov khoom noj raws li tsim nyog).
