Kev kho kom zoo: Qhov kev xaiv ntawm polyaluminum chloride thiab Aluminium Sulfate

Nyob rau hauv kev kho dej lwg, ob qho tib si polyaluminum chloride (PAC) thiab txhuas sulfate tau siv dav uatab kaumCov. Muaj cov sib txawv ntawm cov qauv tshuaj ntawm ob tus neeg sawv cev, ua rau lawv muaj kev ua tau zoo thiab daim ntawv thov. Nyob rau hauv xyoo tas los, PAC tau maj mam ua kom haum rau nws txoj kev kho mob siab thiab nrawm. Hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv ntawm PAC thiab txhuas sulfate hauv kev kho dej kom tsis txhob pab koj xaiv tau ntau txoj kev xaiv paub ntau ntxiv.

Firstly, cia peb kawm txog polyaluminum chloride (PAC). Raws li ib qho inorganic polymer coagulant, PAC muaj solubility zoo thiab tuaj yeem kho cov flocs. Nws plays lub luag haujlwm sib xyaw los ntawm hluav taws xob nruab nrab thiab cov cuab yeej cuab tam, thiab siv ua ke nrog cov flocculant Pam kom zoo tshem tawm impurities nyob rau hauv wastewater. Piv nrog txhuas sulfate, PAC muaj lub peev xwm ua kom muaj zog dua thiab cov dej zoo dua tom qab ntxuav kom huv. Lub caij no, tus nqi ntawm cov dej pac yog 15% -30% qis dua aluminium sulfate. Nyob rau hauv cov nqe lus ntawm kev noj alkalinity hauv dej, PAC muaj qis noj thiab tuaj yeem txo lossis ncua kev txhaj tshuaj alkaline tus neeg sawv cev.

Tom ntej no yog txhuas sulfate. Raws li cov tsoos cheagulant, Txhuas Sulfate Adsorbs thiab Coagulates kuab paug los ntawm txhuas hydroxide colloids tsim los ntawm hydrolysis. Nws tus nqi disquolv Piv nrog PAC, Txhuas Sulfate muaj qhov muaj peev xwm muaj txiaj ntsig zoo thiab ua kom huv cov dej ua tau zoo, thiab cov nqi dej huv huv yog qhov tseem ceeb.

Hais txog kev ua haujlwm ntev, PAC thiab txhuas sulfate muaj cov ntawv thov sib txawv me ntsis; PAC feem ntau yooj yim los tuav thiab cov foos flocs sai sai, uas kho kho cov kev ua tau zoo. Aluminium sulfate, ntawm qhov tod tes, qeeb rau hydrolyze thiab yuav siv sijhawm ntev dua mus ua coagulate.

Aluminium SulfateYuav txo qis cov ph thiab alkanility ntawm cov dej kho, yog li dej qab zib lossis kua qaub yog xav tau rau nruab nrab cov nyhuv. PAC kev daws teeb yog ze rau nruab nrab thiab tsis muaj qhov yuav tsum tau rau txhua tus neeg sawv cev nruab nrab (dej qab zib lossis txiv qaub).

Hais txog kev cia, PAC thiab txhuas sulfate feem ntau yog ruaj khov thiab yooj yim rau khw thiab thauj. Thaum PAC yuav tsum tau muab ntim rau kom tiv thaiv kev nqus dej noo thiab kis tau lub hnub ci.

Ib qho ntxiv, los ntawm qhov pom ntawm kev corrosivity, txhuas sulfate yog ib qho yooj yim siv tab sis ntau corrosive. Thaum xaiv cov coagulants, kev cuam tshuam muaj peev xwm ntawm ob qho tib si ntawm cov khoom siv kho mob yuav tsum tau txiav txim siab.

Hauv cov ntsiab lus xaus,Polyaluminium chloride(PAC) thiab txhuas sulfate muaj lawv tus kheej zoo thiab qhov tsis zoo hauv dej phwj. Zuag qhia tag nrho, PAC yog maj mam ua cov ntsiab lus tseem ceeb vim nws cov peev txheej siab, kev kho kom ceev ceev thiab dav ua v adaptability. Txawm li cas los xij, txhuas sulfate tseem muaj cov txiaj ntsig zoo hauv qee qhov xwm txheej. Yog li ntawd, thaum xaiv ib co paculant, yam xws li kev thov tiag tiag, kev kho mob thiab tus nqi yuav tsum tau txiav txim siab. Xaiv txoj cai coagulant yuav pab txhim kho kev ua haujlwm ntawm kev kho kom zoo.
