Kev kho cov khib nyiab Leachate
Kev kho cov khib nyiab pov tseg
Kev kho cov khib nyiab pov tseg yog tsom rau kev soj ntsuam nrog cov kua uas tawm ntawm qhov chaw pov tseg thiab muaj cov sib xyaw ua ke ntawm cov kab mob. Lub hom phiaj yog tshem tawm cov teeb meem tshuaj thiab cov pa phem los tiv thaiv ib puag ncig muaj kuab paug thiab ua kom cov kua qaub ua tau raws li cov txheej txheem kev tswj hwm kev tso tawm lossis tuaj yeem kho ntxiv rau kev rov siv dua.
Cov yam ntxwv ntawm kev siv khib nyiab pov tseg
Cov pa phem heev: Cov khib nyiab pov tseg tsis tshua muaj paug nrog ntau yam organic thiab inorganic compounds, hnyav hlau, thiab cov kab mob. Nws muaj qib siab ntawm biochemical oxygen xav tau (BOD), tshuaj lom neeg oxygen xav tau (COD), thiab ammonia nitrogen.
Qhov sib txawv ntawm qhov sib txawv: Qhov sib txawv ntawm cov kua dej tuaj yeem sib txawv nyob ntawm lub hnub nyoog ntawm qhov chaw pov tseg, hom khib nyiab pov tseg, thiab ib puag ncig yam. Qhov no ua rau kev kho mob nyuaj dua li cov txheej txheem kho mob yuav tsum tau hloov mus rau ntau qhov sib txawv.
High Toxicity: Cov kab mob paug hauv cov kua qaub tuaj yeem ua rau muaj tshuaj lom thiab ua rau muaj kev pheej hmoo loj rau tib neeg kev noj qab haus huv thiab ib puag ncig yog tias tsis kho kom raug.
Tsawg pH thiab High Salinity: Cov khib nyiab khib nyiab feem ntau muaj pH tsawg thiab salinity siab, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem kho thiab yuav tsum tau muaj kev kho tshwj xeeb.
Cov yam ntxwv ntawm kev siv khib nyiab pov tseg
Multi-Stage Treatment: Vim yog qhov nyuaj ntawm cov kua qaub, cov txheej txheem kev kho mob feem ntau yuav tsum tau ua. Qhov no tej zaum yuav muaj xws li pretreatment kom tshem tawm cov khib nyiab thiab kho cov pH, kev kho mob lom kom zom cov organic teeb meem, thiab kev kho siab heev xws li daim nyias nyias los yog tshuaj oxidation rau kev ua kom huv ntxiv.
Cov txheej txheem aerobic thiab anaerobic: Ob txoj kev kho mob aerobic thiab anaerobic tuaj yeem siv rau kev kho mob leachate. Kev kho mob anaerobic feem ntau yog siv rau cov laus leachate nrog cov organic load siab, thaum kho aerobic yog tsim rau kev kho cov leachate nrog cov ntsiab lus ntawm cov organic.
Sludge Management: Cov txheej txheem kev kho mob tsim cov sludge, uas yuav tsum tau tswj kom zoo thiab pov tseg. Kev kho cov sludge yuav suav nrog kev ua kom tuab, dewatering, thiab pov tseg txoj hauv kev xws li kev pov tseg lossis kev tua hluav taws.
Tshwj xeeb yuav tsum tau rau Disc diffuser Thaum siv nyob rau hauv Biological Aeration Tanks rau khib nyiab leachate kho
Kev Tiv Thaiv Corrosion: Cov khib nyiab pov tseg yog corrosive heev vim nws cov acidic xwm thiab muaj ntau yam tshuaj. Lub disc diffuser yuav tsum tau ua los ntawm cov ntaub ntawv uas tiv taus corrosion los xyuas kom meej lub sij hawm ntev.
High Oxygen Transfer Efficiency: Muab cov pa oxygen siab ntawm kev kho cov kua qaub, lub disc diffuser yuav tsum muaj cov pa oxygen hloov mus rau qhov ua tau zoo los xyuas kom muaj cov pa oxygen txaus rau cov txheej txheem kev kho mob lom.
Muaj peev xwm los tuav Cov Ntsiab Lus Siab: Leachate feem ntau muaj qhov tseem ceeb ntawm cov khib nyiab tshem tawm. Lub diffuser yuav tsum muaj peev xwm tswj tau cov ntsiab lus siab siab no yam tsis muaj clogging lossis txo nws cov kev ua tau zoo.
Kev Kho Kom Yooj Yim: Vim muaj qhov hnyav ntawm kev kho cov kua qaub, cov disc diffuser yuav tsum yooj yim los tswj thiab ntxuav kom ntseeg tau tias kev ua haujlwm ruaj khov.

Kev kho cov khib nyiab pov tseg yog txoj haujlwm nyuaj thiab tseem ceeb los tiv thaiv ib puag ncig thiab tib neeg kev noj qab haus huv. Kev nkag siab txog cov yam ntxwv ntawm cov dej xau thiab siv cov txheej txheem kho kom zoo yog qhov tseem ceeb. Kev siv cov disc diffusers nyob rau hauv cov roj av aeration tso tsheb hlau luam rau kev kho cov tshuaj leachate yuav tsum tau txiav txim siab tshwj xeeb los xyuas kom meej cov pa oxygen hloov tau zoo thiab txhim khu kev qha. Los ntawm kev daws cov teeb meem no, peb tuaj yeem txhim kho cov txiaj ntsig ntawm kev kho cov kua qaub thiab pab txhawb kev tswj cov khib nyiab kom ruaj khov.
