Nrog rau kev loj hlob sai ntawm kev lag luam thiab hauv nroog, siab-concectoration lim dej tau dhau los ua ib qho teeb meem ib puag ncig. Cov teeb meem loj ntawm cov roj ntsha tsis yog muaj cov teeb meem muaj teeb meem loj, tab sis kuj muaj lwm yam kev cuam tshuam nrog kev kho kom zoo nkauj ntawm cov chaw lim dej kom huv. Yog li ntawd, qhov siab siab ntawm kev kho dej kom zoo thiab kev coj qauv txheem yog tshwj xeeb yog ib qho tseem ceeb.
1. Kev txhais thiab cov yam ntxwv ntawm cov siab-siab cov khoom siv kom zoo ntawm cov organic, cov hlau hnyav, tshuaj lom thiab muaj kuab paug. Cov kuab paug nyob hauv cov dej qias neeg hauv cov dej qias neeg nyob deb tshaj qhov chaw pov tseg dav dav, thiab nws tsis yooj yim los kho. Tej zaum yuav muaj ntau hom kev ua qias tuaj, cov hlau hnyav, tshuaj lom neeg tuaj yeem ua rau muaj kuab lom, uas nyuaj rau tshem tawm cov txheej txheem kev kho mob biological.
2. Cov xwm txheej loj ntawm cov tshuaj lom neeg ntau heev: cov dej khib nyiab tsim tawm hauv cov txheej txheem ntawm cov tshuaj lom neeg feem ntau muaj cov tshuaj organic ntau zaus, cov hlau hnyav thiab lwm yam kuab paug. Kws Tshuaj Kho Mob: Cov tshuaj khib nyiab pov tseg feem ntau muaj qhov siab ntawm cov organic, tshuaj tua kab mob, thiab lwm yam, uas yog qhov nyuaj los kho. Down thiab textile kev lag luam: cov dej khib nyiab uas ua los ntawm cov lag luam no feem ntau muaj cov khoom lag luam muaj teeb meem loj ntawm cov organic muaj teeb meem thiab chromaticity. Electroplating thiab metallurgy: khib nyiab muaj cov hlau hnyav thiab cov tshuaj lom neeg muaj kuab lom thiab cov tshuaj lom neeg tau tsim thaum electroplating thiab metallurgy.
3. Cov ntsiab lus thev naus laus zis ntawm cov khoom siv kho kom zoo dua qub, feem ntau los ntawm cov qauv siv hluav taws xob lossis cov kev tshem tawm hauv cov dej khib nyiab, los tsim cov kab mob rau kev kho tom qab. Nws tseem yuav siv cov thev naus laus zis <br> Oxidation Oxidation, Ozone oxidation, dhau los ntawm kev tsim cov organic teeb meem rau cov tshuaj uas yooj yim yooj yim. Siv cov kev ua yeeb yam metabolic ntawm cov kab mob me los tshem cov organic teeb meem hauv dej wastewater. Rau kev sib zog ua kom zoo, cov txheej txheem anaerobic thiab aerobic sib koom ua ke yuav raug coj los txhim kho cov nyhuv kho tau. Lub TIC cov tshuaj hauv dej huv kuj tuaj yeem raug tshem tawm ntawm txoj kev lub cev los ntawm membrane sib tshuam thev naus laus zis xws li ultrafiltration thiab rov qab osmosis. Los ntawm cov tshuaj lom neeg, ion txauv, kos duab thiab lwm yam hnyav hlau kho thev naus laus zis, siv los tshem cov hlau hnyav hauv dej khib nyiab. Yog li ntawd, rau siab siab cov cuab yeej lim dej, nws yog ib qho tseem ceeb heev kom paub meej tias cov txheej txheem kho mob, ua rau pom cov kev ua haujlwm thiab kev tshuaj xyuas kom tsis tu ncua. Yog pom tias muaj teeb meem pom, siv ntsuas raws sijhawm los kho.
Vim muaj tshwj xeeb ntawm nws cov dej ua tau zoo, kev kho kom muaj txiaj ntsig zoo rau kev kho kom nruj muaj cov kev xav tau. Nws yuav tsum muaj cov khoom lag luam zoo, kev paub ua haujlwm, thiab lub tswv yim ntawm kev hloov kho cov khoom hauv zos kom ntseeg tau tias qhov kev siv tshuaj kom zoo rau cov txheej txheem kev kho kom zoo. Jiading Kev tiv thaiv ib puag ncig yog cov Hoobkas loj hlob hauv kev lag luam dej pheebsuab, raws li txawv teb chaws thev naus laus zis, muaj cov khoom siv nruj heev, muaj cov khoom siv nruj heev.
