Dairy Wastewater Treatment
Khoom noj khoom haus Wastewater Treatment Concept
Kev kho cov dej khib nyiab yog hais txog cov txheej txheem siv los kho cov dej ntws tawm los ntawm cov khoom siv mis nyuj, suav nrog cov haujlwm xws li kev ua mis nyuj, cheese tsim, thiab kev ua haujlwm tu. Cov dej khib nyiab no feem ntau yog nplua nuj nyob rau hauv cov ntaub ntawv organic, rog, roj, proteins, thiab lactose, ua rau nws biodegradable heev, tab sis nws kuj muaj peev xwm tsim cov qib siab ntawm Biological Oxygen Demand (BOD) thiab Chemical Oxygen Demand (COD).
Cov yam ntxwv ntawm Dairy wastewater kho
Cov ntsiab lus Organic siab: Cov dej khib nyiab muaj ntau cov roj, roj, cov protein, thiab lactose, ua rau muaj BOD thiab COD ntau ntau.
Fluctuating Composition: Cov dej khib nyiab tuaj yeem sib txawv heev nyob ntawm cov txheej txheem siv mis nyuj tshwj xeeb hauv kev siv, caij nyoog, thiab kev ua haujlwm hloov.
Nutrient-Rich: Cov dej khib nyiab yog nplua nuj nyob rau hauv cov as-ham xws li nitrogen thiab phosphorus, uas tuaj yeem txhawb nqa kev loj hlob ntawm algae hauv cov dej tsis zoo yog tias tso rau hauv cov dej ntuj.
Foaming thiab Scum Formation: Cov rog thiab cov proteins uas tam sim no tuaj yeem ua rau muaj cov npuas dej thiab cov khib nyiab thaum kho, uas yuav tsum tau tuav tshwj xeeb.
Temperature Variability: Cov dej khib nyiab tuaj yeem hloov pauv nyob ntawm cov txheej txheem ntxuav, uas tuaj yeem cuam tshuam rau kev kho mob lom.
Cov yam ntxwv ntawm kev kho cov dej khib nyiab ntawm cov mis nyuj
Kev kho mob ua ntej: Qhov no suav nrog kev tshuaj xyuas kom tshem tawm cov khib nyiab loj, thiab cov roj / roj twj kom ntes cov rog thiab roj.
Kev kho thawj zaug: Sedimentation lossis flotation yog siv los tshem tawm cov khib nyiab thiab cov rog, roj, thiab roj (FOG).
Kev kho mob lom neeg: Cov thev naus laus zis zoo li MBBR (Txiv-Bed Biofilm Reactor) lossis Activated Sludge feem ntau yog siv los txo BOD thiab COD. Cov tshuab no siv cov kab mob aerobic los rhuav tshem cov pa phem.
Kev Kho Mob Thib Ob: Kev kho mob lom lossis tshuaj lom neeg ntxiv tuaj yeem ua haujlwm kom tshem tawm cov as-ham (xws li nitrogen thiab phosphorus).
Kev Kho Mob Thib Ob: Hauv qee kis, kev pom zoo tshaj plaws, tshuaj tua kab mob, lossis polishing cov kauj ruam yog siv los ua kom tau raws li cov qauv tso tawm.
Tshwj xeeb yuav tsum tau rau Disc diffuser Thaum siv nyob rau hauv Biological Aeration Tanks rau mis nyuj haus dej khib nyiab
Kev tiv thaiv rau cov rog thiab roj: Cov disc diffusers yuav tsum tau tsim los tiv thaiv kev txhaws ntawm cov rog, roj, thiab roj (FOG) uas muaj nyob hauv cov dej khib nyiab. Cov ntaub ntawv tshwj xeeb, xws li silicone membranes, tej zaum yuav xav tau.
High Oxygen Transfer Efficiency: Muab cov organic loads siab, cov diffusers yuav tsum xyuas kom muaj cov pa oxygen hloov mus kom muaj cov xwm txheej aerobic tsim nyog rau kev puas tsuaj ntawm cov roj ntsha.
Durability: Diffusers yuav tsum tiv taus qhov sib txawv ntawm cov dej khib nyiab thiab cov ntsiab lus siab ntawm cov organic tsis muaj deteriorating lossis poob efficiency.
Kev Tswj Ua Npuas Ncauj: Kev tso tawm thiab tsim kom zoo yog tsim nyog kom tsis txhob muaj cov npuas dej ntau dhau, uas tuaj yeem cuam tshuam nrog cov txheej txheem aeration thiab kev kho mob.
Kev tu: Kev tu yooj yim thiab kev saib xyuas cov yam ntxwv yog qhov tseem ceeb los tswj kev tsim cov rog thiab lwm yam khoom ntawm diffuser nto.
Xaus
Kev kho cov dej khib nyiab yuav tsum tau ua tib zoo xav txog qhov siab ntawm cov organic load, qhov sib txawv ntawm cov dej khib nyiab, thiab cov teeb meem kev ua haujlwm xws li foaming thiab scum tsim. Cov txheej txheem kev kho mob lom neeg zoo li MBBR muaj txiaj ntsig zoo rau kev txo qis cov pa phem, thaum cov khoom siv hluav taws xob siv hauv cov tso tsheb hlau luam aeration yuav tsum tau tsim los tswj cov yam ntxwv tshwj xeeb ntawm cov khoom siv mis nyuj. Kev xaiv thiab kev saib xyuas kom zoo yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo, ua kom cov dej kho tau raws li cov qauv tso tawm ib puag ncig.
