Nrog rau txoj kev loj hlob sai ntawm industrialization thiab urbanization, high-concentration wastewater tau dhau los ua ib qho teeb meem loj zuj zus. High-concentration wastewater tsis tsuas yog muaj ib tug loj npaum li cas ntawm cov organic teeb meem, inorganic teeb meem, hnyav hlau thiab lwm yam teeb meem, tab sis kuj nws concentration yog deb tshaj li tsim thiab kho lub peev xwm ntawm cov pa kev kho cov dej khib nyiab. Yog li ntawd, qhov siab concentration ntawm kev kho dej khib nyiab thiab cov qauv tso tawm yog qhov tseem ceeb tshwj xeeb.
1. Cov ntsiab lus thiab cov yam ntxwv ntawm cov dej khib nyiab siab siab siab concentration ntawm cov dej khib nyiab, feem ntau yog hais txog cov dej khib nyiab uas muaj cov ntsiab lus siab ntawm cov organic teeb meem, hnyav hlau, tshuaj lom thiab teeb meem thiab lwm yam pa phem. Cov ntsiab lus muaj kuab paug hauv cov dej khib nyiab deb tshaj cov dej khib nyiab dav dav, thiab nws nyuaj rau kev kho. Tej zaum yuav muaj ntau hom kev ua qias tuaj, xws li cov organic teeb meem, cov hlau hnyav, cov khoom siv hluav taws xob, thiab lwm yam. Qee cov pa phem yuav muaj kev cuam tshuam rau cov kab mob thiab cuam tshuam rau cov nyhuv ntawm kev kho mob lom, uas nyuaj rau tshem tawm los ntawm cov qauv kev kho mob lom.
2. Kev tsim cov txheej txheem ntawm cov dej khib nyiab siab heev Kev tsim cov tshuaj lom neeg: cov dej khib nyiab uas tsim tawm hauv cov txheej txheem tshuaj lom neeg feem ntau muaj cov organic teeb meem ntau, cov hlau hnyav thiab lwm yam kuab paug. Kev lag luam kws tshuaj: cov dej khib nyiab tshuaj feem ntau muaj cov ntsiab lus siab ntawm cov organic, tshuaj tua kab mob, thiab lwm yam, uas nyuaj rau kev kho. Kev lag luam dyeing thiab textile: cov dej khib nyiab uas tsim los ntawm cov kev lag luam no feem ntau muaj ntau ntawm biodegradable organic teeb meem thiab chromaticity. Electroplating thiab metallurgy: Cov dej khib nyiab uas muaj cov hlau hnyav thiab cov tshuaj lom yog tsim thaum electroplating thiab metallurgy.
3. Core technology ntawm high-concentration wastewater kho cov cuab yeej High concentration wastewater kho cov cuab yeej, feem ntau yog los ntawm lub cev los yog tshuaj txoj kev los tshem tawm cov khoom loj, tshem tawm cov teeb meem nyob rau hauv cov dej khib nyiab, los tsim tej yam kev mob rau kev kho mob tom ntej. Nws kuj tseem yuav siv cov thev naus laus zis oxidation siab heev xws li Fenton oxidation, ozone oxidation, los ntawm kev tsim cov oxidant muaj zog los hloov cov organic teeb meem rau hauv cov khoom yooj yim degradable. Siv cov txheej txheem metabolic ntawm cov kab mob kom tshem tawm cov organic teeb meem hauv cov dej khib nyiab. Rau cov dej khib nyiab siab, cov txheej txheem anaerobic thiab aerobic ua ke tuaj yeem siv los txhim kho kev kho mob. Cov tshuaj tic hauv cov dej khib nyiab tuaj yeem raug tshem tawm los ntawm txoj hauv kev ntawm lub cev los ntawm kev sib cais cov txheej txheem xws li ultrafiltration thiab thim rov qab osmosis. Los ntawm chemical nag lossis daus, ion pauv, adsorption thiab lwm yam kev siv tshuab hnyav hlau, siv los tshem tawm cov hlau hnyav ions hauv dej khib nyiab. Yog li ntawd, rau cov khoom siv kho dej phwj siab, nws yog ib qho tseem ceeb heev kom ntseeg tau tias cov dej ntws mus txog tus qauv, tsim nyog xaiv cov txheej txheem kho, nruj me ntsis tswj cov txheej txheem kho, ntxiv dag zog rau pretreatment, optimize lub lag luam tsis tu ncua thiab kev soj ntsuam thiab kev soj ntsuam. Yog tias pom muaj teeb meem, siv sijhawm sijhawm los kho.
Vim qhov tshwj xeeb ntawm nws cov dej tsis zoo, kev kho cov dej khib nyiab siab muaj cov kev cai nruj heev rau cov khoom siv. Nws yuav tsum muaj cov khoom siv technology zoo, qhov kev paub dhau los, thiab lub tswv yim ntawm kev hloov kho cov kev ntsuas hauv zos kom paub tseeb tias cov dej ntws tawm ntawm cov khoom siv dej khib nyiab siab ua tau raws li tus qauv. Jiading ib puag ncig kev tiv thaiv yog ib lub Hoobkas laus hauv kev lag luam dej phwj tuaj rau kaum xyoo, raws li nyob rau hauv Jiangsu xeev, hluav taws xob rau tag nrho lub teb chaws, ntsib txawv teb chaws, muaj ib tug nruj cov khoom technology zoo tswj pab neeg.
