Aluminium sulfate ua ib coagulant hauv kev kho dej khib nyiab

Niaj hnub no, ntau tus neeg siv khoom muaj ntau dua thiab siab dua cov kev xav tau ntawm txhuas sulfate, yog li peb lub tuam txhab tau rov qab mus rau qee cov neeg siv khoom.Peb pom tias txawm hais tias muaj cov lus qhia, qee cov neeg tseem tsis nkag siab zoo, thiab lawv tsis quav ntsej qee cov ntsiab lus uas yuav tsum tau saib xyuas.Niaj hnub no, tus editor yuav tham txog txhuas sulfate ua coagulant nrog koj.

Aluminium sulfate tsuas yog haum rau acid sizing, hlau-dawb txhuas sulfate yuav siv tau rau sizing nyob rau hauv acidic thiab nruab nrab ib puag ncig, lub corrosion ntawm lub cev yog ho tsis muaj zog, thiab kev kho mob ntawm cov dej dawb yuav yooj yim dua;polyaluminum chloride tuaj yeem siv nyob rau hauv nruab nrab lossis txawm tias alkaline ntau yam Ua kom muaj txiaj ntsig zoo, tsis yog tsim Al (OH) 3 precipitates sai npaum li cov khoom no, thiab vim yog pre-hydrolysis ntawm polyaluminum chloride, pH tus nqi ntawm lub system. yuav tsis poob qis heev.

Aluminium sulfate kuj ruaj khov hauv huab cua.Thaum nws yog 86.5, nws yuav poob ib feem ntawm cov dej ntawm crystallization, thiab thaum nws yog 250, nws yuav poob tag nrho cov dej ntawm crystallization.Thaum nws yog rhuab, nws nthuav dav thiab ua spongy.Thaum raug rho tawm haujlwm liab, nws tawg mus rau hauv sulfur trioxide thiab txhuas oxide.Nws huab cua thaum tus txheeb ze humidity yog li 25% qis dua.Insoluble yooj yim ntsev precipitate tom qab ntev boiling.Ntxiv mus, ua ke nrog kev kho cov nyhuv ntawm cov kua txhuas sulfate ntawm cov dej khib nyiab, polyaluminum chloride tuaj yeem ua tiav cov txiaj ntsig ntawm kev tshem tawm turbidity, thiab txawm tias lub sijhawm kom ua tiav cov nyhuv ntawm turbidity tshem tawm, tab sis vim nws tus nqi txheeb ze kuj yog siab thiab cov lub sij hawm rau turbidity tshem tawm tsis ntev heev.Piv nrog ferrous sulfate, cov sludge tsim los ntawm txhuas ntsev yog denser, uas tuaj yeem txo cov nqi kho sludge.

Cov lus qhia saum toj no muaj feem xyuam rau txhuas sulfate.Nws tuaj yeem pom los ntawm cov saum toj no tias nws yog qhov tseeb siv aluminium sulfate ua coagulant hauv kev kho cov dej khib nyiab.Yog tias koj tseem tsis nkag siab dab tsi, thov hu rau peb ncaj qha.
