Hauv kev tsim khoom niaj hnub, cov ntawv thov ntawm cov kuab tshuaj organic yog ubiquitous, tag nrho cov luam ntawv thiab ntim tshuaj, diluting, thiab kev cuam tshuam nrog cov kuab tshuaj. Txawm li cas los xij, cov kev siv ib txwm siv thiab pov tseg txoj kev ntawm cov kuab tshuaj tsis yog ua rau cov chaw muaj peev xwm loj heev tab sis kuj tseem ua rau ib puag ncig kev noj qab haus huv thiab kev noj qab haus huv. Nyob rau hauv xyoo tsis ntev los no, nrog kev txhawb nqa ib puag ncig ib puag ncig thiab kev txhim kho kev ua haujlwm txo qis, kev ua haujlwm zoo, yog kev nyiam ntau dua thiab ntau cov lag luam. Kab lus no yuav muab kev nkag siab zoo rau koj txog cov kuab tshuaj rov qab los, pab koj ua tiav qhov teeb meem rau kev lag luam thiab cov txiaj ntsig ib puag ncig hauv kev lag luam.
Dab tsi yog cov kuab rov qab lub tshuab rov qab? Unveiling nws tsis meej
Lub tshuab rov qab zoo, raws li lub npe qhia, yog ntxuav cov kuab tshuaj lossis siv tshuaj lom neeg, yog li siv tau rov ua dua tshiab thiab rov siv dua. Nws ua zoo li "tus txawj ua yees siv," muaj peev xwm hloov cov kuab paug uas yuav txwv tsis pub yuav khoom kim.

Cov tub ntxhais ntawm cov kuab kev rov qab siv lub cav hauv nws txoj kev sib cais thiab cov thev naus laus zis. Tam sim no, cov ntsiab lus muaj kuab tshuaj rov qab thev naus laus zis ntawm kev ua lag luam yog suav nrog:
Distillation rov qab thev naus laus zis: qhov no yog cov thev naus laus zis ntau tshaj plaws. Nws cov ntsiab cai yog ua kom sib txawv ntawm kev sib txawv ntawm cov kuab tshuaj thiab lwm yam khoom (roj, roj, thiab lwm yam) ntawm ntau qhov kub. Cov kuab khib nyiab yog rhuab rau nws lub qhov cub npau npau, ua rau nws ua kom vaporize. Cov kev daws teeb meem yog tom qab ntawd condensed thiab sau, yog li tau txais cov kuab tshuaj ntshiab. Impurities nyob rau hauv distillation tseem. Ua raws li cov qauv cua kub thiab cov qauv txheej txheem, ua yeeb yaj kiab txuas ntxiv mus rau cov kuab cua distillation, thiab cov yeeb yaj kiab sib txawv thiab cov volscosities.
Activated Carbon Adsorption Recovery Technology: This method is mainly used for low-concentration solvent waste gas or wastewater. Nws siv cov cheeb tsam thaj chaw loj thiab cov qauv sib dhos ntawm cov pa roj carbon rau Adsorb Tom qab cov pa roj carbon urpourated, cov kuab tshuaj yog desorbed los ntawm chav, kub nitrogen, lossis lub tshuab nqus tsev thiab tom qab ntawd condensed rau kev rov zoo. Cov thev naus laus zis no yog qhov ua tau zoo rau kev kho cov khoom loj ntawm cov qes-}}} monsentration daws cov vapor.
Membrane Cooline Cooth Technology: Membrane Sib Cais Tshuab yog ib txoj kev tshiab los ua. Nws siv ib qho kev xaiv mem coj ua, tsav los ntawm cov rog sab nraud (xws li cov tshuaj sib txawv), kom ua cov kuab tshuaj me me, yog li kawm tiav kuab tshuaj. Cov ntawv txiav sib tshuam ua ke sib cais thev naus laus zis suav nrog kev sib dhos, vapor permeration, thiab nanofililtration. Lawv muab cov txiaj ntsig zoo xws li kev siv hluav taws xob qis, kev ua haujlwm yooj yim, thiab ua haujlwm tsis tu ncua, thiab yog qhov tshwj xeeb rau kev kho qee yam thiab cua sov {}}} cov ntaub ntawv rhiab.
Ib qho ntxiv, muaj qee cov thev naus laus zis rov qab rau cov kuab tshuaj lossis cov ntawv thov, xws li rho tawm thiab kev nqus. Hauv kev siv cov kev siv, kev lag luam feem ntau xaiv cov thev naus laus zis feem ntau ntawm cov hom pov tseg, thiab impurration Cheebtsam ntawm cov kuab pov tseg, thiab cov kev ua kom zoo nkauj rau cov kuab tshuaj zoo.
Cov txiaj ntsig tseem ceeb ntawm cov kuab rov qab cov tshuab: Vim li cas lawv thiaj nyiam dua?
Txo nqi them ntau:
• Txo cov nqi hloov kho tshiab: rov ua dua tshiab thiab siv cov kuab paug pov tseg tuaj yeem txo cov nqi siv cov nqi ntau lawm, cov nqi qis heev.
• Txo cov nqi khib nyiab pov tseg: cov kuabcum uas muaj kev phom sij yog feem ntau ua rau muaj kev phom sij, thiab lawv qhov kev pov tseg kim thiab cuam tshuam nrog cov txheej txheem cumbersome. Cov kuab tshuaj rov qab tuaj yeem txo qis cov khib nyiab uas tsim tawm, yog li txuag cov kev phom sij khib nyiab loj.
Txhim kho ib puag ncig cov duab thiab lub luag haujlwm ntawm kev sib raug zoo:
• Txo cov kuab paug ib puag ncig: los ntawm kev rov qab los thiab rov ua kom zoo nkauj rau hauv cov huab cua thiab cov dej muaj kuab paug rau ib puag ncig ib puag ncig.
• Ua raws li cov kev cai ib puag ncig: Nquag Soj Ntsuam Cov Kev Cai Rov Qab Pab Rau Cov Kev Cai Ib puag ncig, zam kev nplua nuj thiab kev pheej hmoo.
• Tsim cov duab ntsuab ntsuab: Ua kom pom lub tuam txhab kev cog lus rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, txhim kho hom duab thiab kev lees paub hom.
Txhim kho cov kev ua tau zoo thiab kev nyab xeeb:
• Ua kom cov kuab tshuaj uas ua kom zoo:
• Txhim kho kev nyab xeeb ua haujlwm: txo qhov chaw khaws khoom thiab kev thauj cov kuab tshuaj txo qis ntawm kev nyab xeeb ntawm kev nyab xeeb ntawm kev nyab xeeb cov hluav taws, tawg, thiab txov txeej.
• Txhim kho cov chaw ua haujlwm: Txo cov kuab tshuaj loj yuav pab txhim kho cov pa huab cua zoo thiab tiv thaiv cov neeg ua haujlwm noj qab haus huv.
WDAF daim ntawv thov cov chaw ntawm cov kuab rov ua haujlwm rov qab machine: uas muaj txiaj ntsig?
