Dej yog lub hauv paus ntawm lub neej, peb tsis tuaj yeem nyob tsis muaj dej, txawm li cas los xij, vim muaj kuab lom dej, ntau thaj chaw uas muaj dej tsis txaus thiab dej tsis zoo. Txhawm rau daws cov teeb meem no, ntau tus kws tshawb fawb thiab kws ua haujlwm cuam tshuam lawv tus kheej tshawb fawb thiab kev tsim cov dej kho tshuab. Ntawm lawv, polyaluminum chloride (PAC), ua tus neeg sawv cev dej tseem ceeb, tau siv dav hauv kev ua kom huv si thiab dej phwj.

Qhov kev txiav txim ntawm PAC tau ua tiav los ntawm plaub yam ntawm nws lossis nws cov khoom siv hydrolysis tsim muaj bilayer, chaw nruab nrab, daim ntaub nplaum, thiab adsorption bridging.
Nws precipitates thiab cov ntxaij tawm qhov teeb meem uas tuaj yeem ua rau oxidizing los ntawm cov teeb meem, thiab cov nag lossis daus, ib puag ncig kev phooj ywg, thiab cov khoom siv khib nyiab ib puag ncig, thiab cov khoom siv ceev. Nws tsis tuaj yeem tsuas yog txo cov kev xav tau zoo ntawm cov khoom siv organic, cov kab mob ua kom muaj kuab paug, txo cov tshuaj tsw qab, txo cov acidity thiab alkalinity ntawm dej phwj tuaj, yog li txhawm rau txhim kho cov pa phem ntawm cov dej phwj. PAC yog qhov ntxiv ntxiv rau dej phwj tuaj, uas muaj lub luag haujlwm tseem ceeb hauv cov dej phwj.
Cov yam ntxwv
PAC yog ib qho inorganic polymer coagulant. Nws tuaj yeem zoo siab lees paub cov lus hais tseg thiab colloidal ions hauv dej, sib sau ua ke, kev tawm dag zog thiab precipitate los ntawm kev ua kom zoo thiab nag lossis nag li. Piv nrog rau lwm cov coagulants, PAC muaj cov kev siv thiab hloov kho kom yooj yim rau cov khoom loj loj thiab muaj cov nag lossis daus nag lossis daus. Nws muaj ntau cov nqi ph tus nqi haum (5-9), thiab tus nqi PH thiab alkalinity ntawm cov dej kho yog me me. Thaum cov dej kub yog tsawg, nws tseem tuaj yeem tswj hwm cov txiaj ntsig ruaj khov. Nws alkalinity yog siab dua lwm cov txhuas thiab cov ntsev nyeem, thiab nws muaj cov yaig me me rau cov cuab yeej.
Daim ntawv thov
PAC yog hom tshiab inorganic macromolecule Coagulant nrog kev ua haujlwm siab. Nws yog dav siv nyob rau hauv cov dej haus, kev siv dej muaj kev lag luam, kev lag luam efficent, lag luam nqa cov pab dej tsis tau. Nws muaj dav dav-muaj kev yoog raws cov dej ntawm ntau qhov kub thiab lub solubility zoo. PAC yog me ntsis corrosive thiab haum rau tsis siv neeg siv hluav taws xob thiab yooj yim rau kev ua haujlwm.

PAC yog ib qho tseem ceeb ua ke hauv thaj teb kom huv. Nws tau ua kom muaj txiaj ntsig zoo rau qhov kub thiab txias, qis lub tshuab turbidity thiab lub siab turbidity dej. Txawm li cas los xij, txij li nws monomer reacts nrog cov organic teeb meem los tsim cov tshuaj uas muaj kev puas tsuaj rau tib neeg kev noj qab haus huv, nws yog ib qho tseem ceeb kom paub meej tias cov pac hauv dej huv.
