COD VS BOD: Nkag siab qhov txawv thiab qhov tseem ceeb

Taw qhia

Thaum nws los txog rau kev txheeb xyuas ib puag ncig thiab kev kho dej khib nyiab, ob qhov tsis tseem ceeb feem ntau tuaj ua si - COD thiab BOD. COD thiab BOD ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov dej zoo thiab ntsuas cov pa phem. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov sib txawv ntawm COD thiab BOD, lawv qhov tseem ceeb hauv kev ntsuas ib puag ncig, thiab lawv yuav ua li cas thiaj li ua kom muaj kev noj qab haus huv ecosystem.

COD VS BOD: Nkag siab qhov txawv qhov tseem ceeb

Kev txhais thiab lub ntsiab lus

COD: Chemical Oxygen Demand, abbreviated as COD, yog ib qho kev ntsuas ntawm tag nrho cov pa oxygen xav tau rau cov tshuaj oxidation ntawm cov organic thiab inorganic hauv dej. Nws sawv cev tag nrho cov pa phem nyob rau hauv cov qauv dej.

BOD: Biochemical Oxygen Demand, hu ua BOD, ntsuas tus nqi ntawm cov pa oxygen uas siv los ntawm cov kab mob thaum rhuav tshem cov organic teeb meem hauv dej. BOD yog qhov tseem ceeb qhia txog qib ntawm cov pa phem hauv lub cev dej.

Kev ntsuas thiab ntsuas

COD: COD ntsuas hauv milligrams ib litre (mg / L) ntawm oxygen.

BOD: BOD kuj ntsuas hauv milligrams ib litre (mg / L) ntawm oxygen.

Txheej txheem thiab Timeframe

COD: Kev xeem COD muab cov txiaj ntsig sai thiab feem ntau ua tiav hauv ob peb teev.

BOD: Kev kuaj BOD yog lub sijhawm siv sijhawm, siv sijhawm ntau hnub los ua kom tiav, vim nws xav kom cov kab mob txhawm rau txhawm rau cov organic.

rhiab heev rau cov tshuaj inorganic

COD: COD ntsuas ob qho tib si organic thiab inorganic tshuaj, ua rau nws tsis tshua meej rau cov pa phem.

BOD: BOD tshwj xeeb tsom rau cov khoom siv organic, muab qhov tseeb dua sawv cev ntawm cov pa phem hauv cov organic.

Environmental Implications

COD: COD qib siab qhia tias muaj ntau yam kuab paug, suav nrog cov organic thiab inorganic tebchaw, ua rau txo qis cov pa oxygen thiab muaj peev xwm ua rau lub neej hauv dej.

BOD: Kev nce qib BOD qhia tau hais tias muaj qhov tseem ceeb ntawm biodegradable organic teeb meem, uas tuaj yeem ua rau cov pa oxygen, ua rau lub neej hauv dej raug kev txom nyem lossis tuag.

Kev siv tau zoo hauv Kev Ntsuam Xyuas Dej Zoo

COD: COD yog qhov tseem ceeb rau kev tshuaj xyuas cov qauv dej thiab txheeb xyuas qhov chaw muaj kuab paug. Nws muab cov lus qhia thawj zaug ntawm dej paug tab sis tsis muab cov duab meej ntawm cov organic pollution's biodegradability.

BOD: BOD yog qhov muaj txiaj ntsig zoo rau kev nkag siab txog biodegradability ntawm cov pa phem organic, muab kev nkag siab rau hauv dej tus kheej lub peev xwm.

Qhov tseem ceeb hauv kev kho dej khib nyiab

COD: Hauv cov chaw kho dej khib nyiab, kev sim COD pab saib xyuas kev kho mob kom zoo, kom ntseeg tau tias cov pa phem raug txo kom qis rau ib puag ncig.

BOD: Kev ntsuam xyuas BOD ua lub luag haujlwm tseem ceeb hauv kev ntsuas qhov ua tau zoo ntawm cov txheej txheem kev kho mob lom neeg, vim nws ntsuas qhov tseeb cov organic muaj nyob hauv dej.

Cov xwm txheej cuam tshuam rau COD thiab BOD qib

• Kub thiab huab cua
• Hom Pollutants
• Kev muaj cov Inhibitors
• Kev ua ntawm microbial

Cov lus nug nquag nug (FAQs)

Dab tsi yog qhov txawv ntawm COD thiab BOD?

COD thiab BOD ntsuas cov pa oxygen hauv dej, tab sis COD suav nrog oxidation ntawm ob qho tib si organic thiab inorganic tshuaj, thaum BOD tsom rau cov organic teeb meem nkaus xwb.

Vim li cas COD ntsuas nrawm dua li BOD?

Kev ntsuam xyuas COD vam khom rau cov tshuaj oxidation, uas ua rau cov txiaj ntsig tau sai dua, thaum BOD cov kev sim xav kom muaj kev puas tsuaj ntawm cov organic teeb meem los ntawm cov kab mob, siv ob peb hnub.

COD thiab BOD siab npaum li cas cuam tshuam rau lub neej hauv dej?

COD qib siab ua rau txo qis hauv cov pa oxygen, cuam tshuam rau lub neej hauv dej tsis zoo. Kev nce qib BOD kuj tseem ua rau cov pa oxygen, ua rau muaj kev phom sij rau ntses thiab lwm yam kab mob.

Dab tsi yog qhov tseem ceeb ntawm COD thiab BOD hauv cov dej khib nyiab?

COD thiab BOD hauv cov dej khib nyiab feem ntau yog los ntawm cov dej phwj tuaj hauv tsev, cov khoom siv hluav taws xob, thiab cov dej ua liaj ua teb uas muaj cov organic thiab inorganic pollutants.

Cov chaw kho dej khib nyiab siv COD thiab BOD cov ntaub ntawv li cas?

Cov chaw kho dej khib nyiab siv COD thiab BOD cov ntaub ntawv los saib xyuas kev ua haujlwm ntawm lawv cov txheej txheem kev kho mob, kom ntseeg tau tias cov pa phem raug txo mus rau qib siab.

Puas muaj cov cai tshwj xeeb rau COD thiab BOD qib?

Yog lawm, cov kev cai ib puag ncig tau teeb tsa cov qauv siab tshaj plaws COD thiab BOD qib los tiv thaiv lub cev dej thiab tswj kom muaj kev noj qab haus huv ecosystem.

Xaus

Kev nkag siab qhov sib txawv ntawm COD thiab BOD yog qhov tseem ceeb rau kev ntsuas dej zoo thiab saib xyuas cov pa phem. COD muab peb lub ntsiab lus dav dav ntawm tag nrho cov pa phem, thaum BOD tshwj xeeb tsom rau cov pa phem. Ob qho kev ntsuas ua si tseem ceeb hauv kev kho dej khib nyiab thiab kev txheeb xyuas ib puag ncig. Los ntawm kev ua raws li cov qauv kev tswj hwm thiab siv cov txheej txheem ntsuas kom raug, peb tuaj yeem ua qhov tsim nyog los tiv thaiv peb lub cev dej thiab ua kom muaj kev ruaj ntseg yav tom ntej.
