BOD yog dab tsi?
BOD (Biochemical Oxygen Demand): yog hais txog qhov loj ntawm cov pa oxygen uas xav tau hauv cov txheej txheem biochemical ntawm cov kab mob hauv dej kom decompose organic teeb meem nyob rau hauv aerobic tej yam kev mob. Txhawm rau ua kom qhov ntsuas qhov ntsuas ntawm BOD sib piv, lub sijhawm feem ntau tau teev tseg, thiab ntsuas cov pa oxygen hauv dej. Feem ntau, tsib hnub siv, hu ua tsib hnub biochemical oxygen xav tau, uas tau sau tseg ua BOD5, thiab tsib hnub biochemical oxygen xav tau feem ntau siv. . Qhov loj dua tus nqi BOD, ntau cov organic teeb meem muaj nyob rau hauv dej, thiab yog li ntawd qhov ua paug loj dua.
BOD yog qhov ntsuas qhov ntsuas ib puag ncig siv los saib xyuas cov pa phem ntawm cov organic hauv dej. Organic teeb meem tuaj yeem decomposed los ntawm cov kab mob. Oxygen tau noj hauv cov txheej txheem no. Yog tias cov pa oxygen yaj hauv dej tsis txaus los muab cov kev xav tau ntawm cov kab mob, lub cev dej yuav cuam tshuam nrog lub xeev muaj kuab paug.

MBBRs ua haujlwm li cas
Cov txheej txheem MBBR siv cov khoom siv yas ntab ntab (media) nyob rau hauv lub tank aeration kom muaj cov kab mob ntau ntxiv los kho cov dej khib nyiab. Microorganisms siv cov organic teeb meem. Cov xov xwm muab cov cheeb tsam ntxiv rau cov kab mob lom kab mob kom txuas mus rau thiab loj hlob hauv lub tank aeration. Qhov chaw nce saum npoo yuav txo cov hneev taw ntawm lub tank yuav tsum tau kho cov dej khib nyiab. Qhov nruab nrab yog tsis tu ncua agitated los ntawm huab cua npuas los ntawm lub aeration system, uas ntxiv oxygen nyob rau hauv qab ntawm thawj compartment ntawm lub aeration tank. Microorganisms siv cov organic teeb meem. Nws muaj superior efficiency thiab tus nqi piv rau cov kev kho mob theem nrab.
Aquasust muaj kev koom tes nrog lwm lub ntiaj teb nto moo hom hauv kev kho dej, tab sis peb tsis tuaj yeem pom ntawm no vim peb muaj kev pom zoo nrog lawv.
