Lub tswv yim Acid Recovery Systems rau kev txuag nqi thiab kev pab cuam ib puag ncig

Hauv kev lag luam toj roob hauv pes, kev tswj hwm ntsuab ntawm cov kua qaub-raws li cov tswv yim tag nrho yog ib qho kev txhawj xeeb tseem ceeb, txhua qhov kev xav ntawm nyiaj txiag thiab ib puag ncig. Kev ntxuav cov kua qaub thiab cov dej khib nyiab tuaj yeem ua rau lub sijhawm loj ntawm cov lus teb siv cov kua qaub, uas ua rau muaj kev xav tau zoo heev hauv cov lus pov tseg, kev kho, thiab kev rov ua dua ntawm cov khoom siv kua qaub huv. Txhawm rau tiv nrog cov teeb meem no, kev txhim kho cov txheej txheem kho cov kua qaub niaj hnub tau tshwm sim los ua ib txoj hauv kev, muab cov koob hmoov zoo rau cov pab pawg thiab ib puag ncig.

Ib qho ntawm tus naj npawb ib tus neeg tsav tsheb rau kev siv cov kua qaub kho cov qauv yog lub peev xwm rau kev txuag nqi zoo. Cov txheej txheem pov tseg cov kua qaub ib txwm siv, uas suav nrog kev tsis sib haum xeeb thiab kev pov tseg, tej zaum yuav yog txhua qhov peev txheej-kwv yees thiab nyiaj txiag hnyav. Los ntawm kev tswj hwm lub cev kho cov kua qaub, cov pab pawg tuaj yeem rov ua dua thiab rov siv cov lus teb siv cov kua qaub, txo qis qhov xav tau kom tau txais cov kua qaub huv si thiab cov nqi pov tseg.

Tsis tas li ntawd, cov qauv niaj hnub no tseem ua rau muaj kev cuam tshuam rau ib puag ncig kev ruaj ntseg. Kev kho kom zoo thiab rov siv cov lus teb cov kua qaub txo qis ntawm cov khoom pov tseg uas tsis muaj kev nyab xeeb tsim tawm, yog li txo cov load ntawm cov chaw pov tseg thiab cov chaw pov tseg. Qhov no, nyob rau hauv lem, txo qis cov pa roj carbon hneev taw thiab ib puag ncig cuam tshuam txog kev lag luam dav dav.

Ntawm lub plawv coronary ntawm cov kua qaub kho cov qauv yog cov thev naus laus zis zoo tshaj plaws uas ua rau muaj kev sib cais sib txawv thiab kev paub txog kev paub. Cov no kuj tseem muaj xws li:

Membrane filtration: Tshwj xeeb daim nyias nyias-raws li cov qauv tag nrho tuaj yeem xaiv tshem tawm cov kab mob los ntawm cov kua qaub siv, ua ib qho nyiaj pub dawb rau kev kho thiab rov qab siv cov kua qaub kua qaub.
Ion alternate resins: Ion alternate resins tuaj yeem xaiv tshem tawm cov impurities los ntawm cov kua qaub, tso cai rau kev tsim dua tshiab thiab rov siv dua cov kua qaub.
evaporation thiab distillation: Cov tswv yim evaporation thiab distillation tuaj yeem mloog cov kua qaub siv, ua kom sib nrug ntawm cov kab mob thiab dej, ua kom muaj txiaj ntsig zoo rau kev kho cov kua qaub.
Electrochemical txoj kev: Electrochemical cov txheej txheem, uas suav nrog electrodialysis thiab electrochemical oxidation, tuaj yeem ua kom zoo dua qub thiab ua kom huv cov kua qaub, txo qhov xav tau rau cov kua qaub ntxiv.
Kev ua raws li cov qauv kho cov kua qaub tam sim no tsis yog qhov zoo tshaj plaws muab cov koob hmoov nyiaj txiag tab sis kuj tseem ua rau muaj kev ruaj ntseg ntawm kev lag luam. Los ntawm kev txo qis kom tsawg ntawm cov kua qaub huv thiab txo qis lub sijhawm ntawm cov pov tseg tsis zoo, cov pab pawg tuaj yeem nthuav tawm lawv txoj kev mob siab rau ib puag ncig lub luag haujlwm thiab ua raws li cov cai nruj dua thiab ntau dua.

Tsis tas li ntawd, kev txhim kho ntawm cov lus teb niaj hnub no tau txhawb kev sib koom tes ntawm cov koom tes ua lag luam, kev kawm, thiab cov tsev kawm tshawb fawb. Txoj kev sib koom tes no tau ua rau tsis muaj kev txhim kho ntawm cov kua qaub kho tshuab, qhov tseem ceeb rau kev ua haujlwm zoo, kev ntseeg siab, thiab tus nqi zoo.
