Yog Aluminium Sulfate Teeb meem rau tib neeg

Hais lus yooj yim, nyob rau hauv cov xwm txheej ntawm kev siv raws li cov qauv kev nyab xeeb thoob ntiaj teb thiab cov cai,aluminium sulfatemuaj kev nyab xeeb rau tib neeg lub cev thiab tsis ua rau muaj kev phom sij rau kev noj qab haus huv.

Aluminium sulfate yog siv dav hauv coagulant hauv dej kho, papermaking, textile manufacturing thiab industrial wastewater kho. Qhov ntau npaum ntawm txhuas sulfate siv thiab cov seem ntawm txhuas hauv dej yog ob qho tib si nruj me ntsis tswj. Tsuas yog nyob rau hauv siab ntau, tsis yog - tus qauv raug lossis kev ua haujlwm tsis zoo tuaj yeem ua rau khaus tawv nqaij, qhov muag lossis ua pa.

Yog li ntawd, lo lus teb tsis yog ib qho yooj yim "yog" lossis "tsis yog". Zoo li feem ntau cov tshuaj, nws txoj kev nyab xeeb nyob ntawm seb nws siv li cas, qhov ntau npaum li cas, thiab seb nws puas ua raws li cov cai thiab cov qauv kev nyab xeeb. Thaum thov kom raug thiab nyob rau hauv cov kev txwv, aluminium sulfate yog suav tias yog kev nyab xeeb rau tib neeg. Kab lus no yuav tshuaj xyuas kev nyab xeeb, kev noj qab haus huv thiab kev cia siab ntawm aluminium sulfate hauv kev kho dej haus los ntawm kev tshawb fawb pom.

Aluminium sulfate yog ib qho inorganic ntsev compound nrog cov tshuaj formula Al2 (SO4) 3, muaj nyob rau hauv daim ntawv ntawm cov hmoov dawb, granules los yog flakes. Nws muaj cov coagulation zoo heev thiab tuaj yeem ua rau tshem tawm cov khib nyiab thiab colloidal impurities hauv dej kom sai coagulate thiab khom thaum kho dej.

Cov kev siv tseem ceeb ntawm aluminium sulfate muaj xws li:

• Cov dej haus thiab kev kho dej hauv nroog
• Kev kho dej khib nyiab
• Papermaking thiab sizing
• Textile dyeing thiab xov
• Tawv ua
• Pigments thiab chemical intermediates

......

Vim nws tus nqi siab -kev ua tau zoo thiab kev ua haujlwm ruaj khov, aluminium sulfate tseem yog ib qho ntawm cov dej siv ntau tshaj plaws.coagulantshauv ntiaj teb no.

Koj tuaj yeem nyiam:Dab tsi yog Aluminium Sulphate siv rau?

Los ntawm kev tshawb fawb thiab kev tswj xyuas, tsuav yog siv raws li cov qauv kev nyab xeeb thiab kev tswj hwm, aluminium sulfate tsis muaj kev phom sij rau tib neeg lub cev.

Seb puas muaj cov tshuaj "ua phem" yog nyob ntawm qhov ntau npaum thiab kev sib cuag. Txawm hais tias cov khoom siv xws li ntsev, cawv, lossis tshuaj tuaj yeem ua rau muaj kev phom sij ntau dhau. Qhov ntau npaum ntawm txhuas sulfate ntxiv rau hauv kev kho dej yog tswj nruj heev, thiab cov qib txhuas seem hauv cov dej kho tau khaws cia deb dua li qhov pib uas yuav ua rau muaj teeb meem kev noj qab haus huv. Yog li ntawd, qhov teeb meem tseem ceeb tsis yog tshuaj lom neeg nws tus kheej, tab sis siv kom raug thiab muaj lub luag haujlwm.

Kev cuam tshuam rau cov dej haus

Aluminium sulfate feem ntau yog siv los ua coagulant hauv kev kho dej haus. Nws khi nrog cov khoom zoo, cov organic teeb meem, thiab impurities, tsim flocs uas raug tshem tawm los ntawm sedimentation thiab pom. Tom qab ntawd feem ntau ntawm cov txhuas tau qhia thaum kho tau raug tshem tawm nrog rau cov sludge. Qhov seem seem ntawm cov dej haus yog tsawg heev.

Lub koom haum World Health Organization (WHO) hais tias:Aluminium concentrations hauv dej haus txog li 0.1-0.2 mg/L yog nyab xeeb.

Hauv qhov tiag -kev kho dej hauv ntiaj teb, dej kho feem ntau ua tau raws li cov qauv no.

Daim tawv nqaij thiab qhov muag sib cuag

Nyob rau hauv high concentrations, aluminium sulfate yog me ntsis acidic thiab tej zaum yuav ua rau khaus ntawm daim tawv nqaij thiab ob lub qhov muag. Txawm li cas los xij, qhov xwm txheej no feem ntau tshwm sim thaum muaj kev tsim khoom lossis kev tuav cov txheej txheem, tsis yog thaum kawg - cov neeg siv qib. Cov cuab yeej tiv thaiv tus kheej kom raug (PPE), xws li hnab looj tes, tsom iav kev nyab xeeb, khaub ncaws tiv thaiv, txaus los tshem tawm cov kev pheej hmoo no.

Inhalation thiab noj

Inhaling aluminium sulfate plua plav tuaj yeem ua rau lub ntsws ua pa.

Kev noj ntau ntau yuav ua rau mob plab hnyuv.

Cov kev pheej hmoo no tsuas yog txwv rau ib puag ncig kev lag luam thiab tswj tau yooj yim los ntawm cov txheej txheem tuav kom raug thiab kev tswj xyuas kev nyab xeeb.

Cov lus teb yog yog. Aluminium sulfate tau siv hauv kev kho dej thoob ntiaj teb rau ntau tshaj 100 xyoo thiab tseem yog ib qho ntawm cov paub tab thiab txhim khu kev qha coagulants.

Nws qhov zoo muaj xws li:

• Stable coagulation nyhuv
• Kev ua haujlwm yooj yim
• Tus nqi -kev ua tau zoo
• Adaptable rau ntau yam dej zoo
• Yuav siv tau ua ke nrogpolyaluminium chloride(PAC) thiab hlau -raws li coagulants

Koj tuaj yeem nyiam:Qhov txawv ntawm PAC thiab Aluminium Sulfate yog dab tsi?

Vim nws txoj kev nyab xeeb thiab kev ntseeg tau, aluminium sulfate tseem siv dav hauv cov chaw kho dej thoob ntiaj teb niaj hnub no.

Ntau lub koom haum thoob ntiaj teb thiab tsoomfwv nruj tswj hwm cov qib txhuas hauv cov dej haus:

• WHO (Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb): Tsawg dua lossis sib npaug li 0.2 mg / L
• EPA (United States Environmental Protection Agency): Pom zoo ntau yam 0.05–0.2 mg/L
• European Union Cov Lus Qhia Txog Kev Haus Dej: Tsawg dua lossis sib npaug li 0.2 mg / L

Cov qauv no xyuas kom meej tias txhuas sulfate siv kev nyab xeeb hauv kev kho dej.

Rau industrial siv:

• Khaws rau hauv qhov chaw qhuav, zoo - qhov cua
• Khaws kom deb ntawm cov khoom muaj zog alkaline
• Thaum lub sijhawm ua haujlwm, yuav tsum hnav hnab looj tes, tsom iav thiab plua plav, thiab ua raws MSDS cov lus qhia

Nrog rau kev tswj kom zoo, aluminium sulfate muaj kev nyab xeeb tag nrho.

• Tus nqi zoo heev -kev ua tau zoo piv
• Pov thawj thiab paub tab technology
• Txhim khu kev coagulation efficiency
• Ntev keeb kwm ntawm kev thov thoob ntiaj teb
• Ua raws li cov qauv dej haus thoob ntiaj teb

Vim cov yam ntxwv no, txhuas sulfate yeej ib txwm yog ib qho khoom tseem ceeb thiab tseem ceeb hauv cov dej hauv nroog, kev kho dej thiab dej haus thaum muaj xwm ceev.

Txhawm rau suav nrog, nyob rau hauv cov xwm txheej ntawm cov txheej txheem tsim khoom, kev siv ntau npaum li cas, thiab ua raws li cov qauv thoob ntiaj teb, aluminium sulfate muaj kev nyab xeeb rau tib neeg siv. Qhov teeb meem tiag tiag tsis yog siv tshuaj, tab sis seb lawv puas siv: Kev tshawb fawb, raug cai, thiab kev tshaj lij.

Los ntawm kev ua raws li cov lus qhia kev nyab xeeb, hnav cov cuab yeej tiv thaiv tsim nyog, tswj hwm qhov ntau npaum li cas, thiab ua raws li lub teb chaws thiab thoob ntiaj teb cov qauv, peb tuaj yeem ua kom muaj txiaj ntsig zoo ntawm txhuas sulfate hauv kev kho dej thiab kev tsim khoom lag luam, thaum txo qis kev pheej hmoo.
