Coal slime water treatment

Coal slime dej yog cov khoom lag luam tail dej uas tsim los ntawm kev npaj cov thee ntub dej, uas muaj ntau cov coal slime hais thiab yog ib qho ntawm cov pa phem tseem ceeb ntawm cov mines.Mucus dej yog ib tug complex polydisperse system.Nws yog tsim los ntawm qhov sib txawv ntawm qhov ntau thiab tsawg, cov duab, qhov ntom ntom thiab lithofacies sib xyaw ua ke sib txawv.

qhov chaw:

Coal mine slurry dej tuaj yeem muab faib ua ob pawg: ib qho yog tsim los ntawm kev ntxuav cov thee nrog lub hnub nyoog luv dua geological thiab ntau dua cov hmoov tshauv thiab impurity;lwm yam yog tsim thaum lub sij hawm ntxuav txheej txheem nrog lub hnub nyoog geological ntev thiab zoo dua cov thee ntawm raw thee ntau lawm.

feature:

Cov ntxhia muaj pes tsawg leeg ntawm coal slime yog qhov nyuaj

Qhov loj me me thiab cov hmoov tshauv ntawm cov coal slime muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm flocculation thiab sedimentation.

Nyob ruaj khov hauv qhov xwm txheej, nyuaj rau kev ua haujlwm

Nws koom nrog ntau qhov chaw, xav tau kev nqis peev loj, thiab nyuaj rau kev tswj hwm

ua mob:

Cov khib nyiab pov tseg hauv thee ntxuav cov dej khib nyiab ua paug rau lub cev dej thiab cuam tshuam rau kev loj hlob ntawm tsiaj thiab nroj tsuag

Coal Wastewater Residue Chemical Pollution Ib puag ncig

Kev ua qias tuaj ntawm cov tshuaj lom neeg nyob hauv Coal Wastewater

Vim qhov nyuaj thiab ntau haiv neeg ntawm cov dej slime, cov kev kho mob thiab cov teebmeem ntawm cov dej slime txawv.Txoj kev kho dej slime feem ntau suav nrog cov txheej txheem ntuj tsim, lub ntiajteb txawj nqus concentration sedimentation method thiab coagulation sedimentation method.

natural nag xob nag cua

Yav dhau los, thee npaj cov nroj tsuag feem ntau tso cov slime dej ncaj qha mus rau hauv lub slime sedimentation tank rau ntuj nag lossis daus, thiab cov dej ntshiab tau siv dua.Txoj kev no tsis tas yuav tsum tau ntxiv cov tshuaj, txo cov nqi tsim khoom.Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho cov thee mining mechanization, cov ntsiab lus ntawm cov thee zoo hauv cov pob zeb uas tau xaiv tau nce ntxiv, uas ua rau muaj teeb meem rau kev kho cov dej slime.Nws feem ntau siv sijhawm hnub lossis ntau lub hlis rau ntau cov khoom zoo kom daws tau tag nrho hauv cov dej slime.Feem ntau hais lus, thee slime dej nrog loj particle loj, tsis tshua muaj concentration, thiab siab hardness yog ib qho yooj yim rau precipitate lawm, thaum cov ntsiab lus ntawm nplua hais thiab av nplaum minerals yog loj, thiab ntuj los nag yog nyuaj.

concentration ntawm gravity

Tam sim no, feem ntau cov thee npaj cov nroj tsuag siv lub ntiajteb txawj nqus concentration sedimentation txoj kev los kho cov slime dej, thiab lub ntiajteb txawj nqus concentration sedimentation txoj kev feem ntau siv cov txheej txheem thickener.Tag nrho cov dej slime nkag mus rau hauv cov thickener kom mloog zoo, cov dej ntws yog siv los ua cov dej ntws, thiab cov dej hauv qab yog diluted thiab tom qab ntawd flotation, thiab cov flotation tailings tuaj yeem tawm sab nraum cov nroj tsuag rau kev pov tseg lossis coagulation thiab kev kho sedimentation.Piv nrog rau ntuj nag lossis daus, lub ntiajteb txawj nqus concentration los nag txoj kev muaj peev xwm ua haujlwm loj thiab ua haujlwm siab.Cov cuab yeej siv feem ntau suav nrog cov thickeners, lim presses, thiab lim.

Txoj kev coagulation sedimentation

Cov ntsiab lus ntawm cov thee metamorphic qis hauv kuv lub tebchaws yog qhov siab, thiab feem ntau ntawm cov pa roj carbon dioxide tsawg yog cov av nkos raw cov thee.Lub resulting coal slime muaj cov ntsiab lus dej siab thiab cov khoom zoo, ua rau nws nyuaj rau kev daws teeb meem.Coagulation feem ntau yog siv nyob rau hauv cov thee npaj cov nroj tsuag los kho cov slime dej, uas yog, los ntawm kev ntxiv cov tshuaj los daws thiab cais tshem tawm cov khib nyiab nyob rau hauv cov dej slime nyob rau hauv daim ntawv ntawm loj hais los yog xoob flocs, uas yog ib tug ntawm cov tseem ceeb txhais tau tias ntawm sib sib zog nqus clarification. dej qab zib..Kev kho coagulation nrog inorganic coagulants hu ua coagulation, thiab kev kho coagulation nrog polymer tebchaw hu ua flocculation.Kev siv ua ke ntawm coagulant thiab flocculant tuaj yeem txhim kho cov txiaj ntsig ntawm kev kho dej slime dej.Feem ntau siv cov tshuaj muaj xws li inorganic flocculants, polymer flocculants, thiab microbial flocculants.
