Kana zvasvika pakuongororwa kwezvakatipoteredza uye kurapwa kwemvura yetsvina, maviri akakosha ma paramita anowanzo tamba - COD neBOD. Ose ari maviri COD neBOD anoita mabasa akakosha mukuona kunaka kwemvura uye kuongorora kusvibiswa kwemazinga. Muchinyorwa chino, tichaongorora mutsauko uripo pakati peCOD neBOD, kukosha kwavo mukuongororwa kwezvakatipoteredza, uye mabatiro avanoita kuita kuti ive neutano hwakanaka.
COD VS BOD: Kunzwisisa Misiyano Yakakosha
Tsanangudzo uye Zvinorehwa
COD: Chemical Oxygen Demand, yakapfupikiswa seCOD, chiyero chehuwandu hwehuwandu hweokisijeni inodiwa kune kemikari oxidation yeorganic uye inorganic zvinhu mumvura. Inomiririra huwandu hwekusvibiswa kwese mumuenzaniso wemvura.
BOD: Biochemical Oxygen Demand, inozivikanwa seBOD, inoyera huwandu hweokisijeni yakanyungudika inopedzwa netwupukanana panguva yekupwanya organic zvinhu zviripo mumvura. BOD chiratidzo chakakosha chehuwandu hwekusvibiswa kwehupenyu mumuviri wemvura.
Kuyera uye Zvikamu
COD: COD inopimwa nemamilligrams parita (mg/L) yeokisijeni.
BOD: BOD inoyerwawo nemamilligrams parita (mg/L) yeokisijeni.
Maitiro uye Nguva yakatarwa
COD: Iyo COD bvunzo inopa nekukurumidza mhinduro uye inowanzopedzwa mukati memaawa mashoma.
BOD: Muedzo weBOD unotora nguva, uchitora mazuva akati wandei kuti upedze, sezvo zvichitoda kuti utachiona huparadze organic matter.
Sensitivity kune Inorganic Substances
COD: COD inoyera zvese organic uye inorganic zvinhu, zvichiita kuti ive shoma kune organic kusvibiswa.
BOD: BOD inonyanya kutarisisa pane organic zvinhu, ichipa yakanyatso kumiririra ye organic kusvibiswa mazinga.
Mamiriro Ezvakatipoteredza
COD: High COD mazinga anoratidza kuvepo kwezvakasiyana zvinosvibisa, zvinosanganisira organic uye inorganic komisheni, zvichikonzera kudzikira kunyungudika oksijeni uye zvinogona kukanganisa hupenyu hwemumvura.
BOD: Kukwidziridzwa kweBOD mazinga anoratidza huwandu hwakawanda hwezvinhu zvipenyu zvinogona kuparara, izvo zvinogona kuderedza mazinga eokisijeni, zvichiita kuti hupenyu hwemvura hutambure kana kuparara.
Kubatsira muKuongorora Kwemhando Yemvura
COD: COD yakakosha pakuongorora masampuli emvura uye kuona kusvibiswa kwenzvimbo. Inopa chiratidzo chekutanga chekusvibiswa kwemvura asi haipe mufananidzo wakajeka weiyo organic pollution's biodegradability.
BOD: BOD iparamendi yakakosha yekunzwisisa kusvibiswa kwezvinhu zvinosvibisa zvipenyu, ichipa ruzivo rwekuzvinatsa kwemvura.
Kukosha Mukuchenesa Mvura Yakasviba
COD: Muzvidyarwa zvekuchenesa mvura yetsvina, kuongororwa kweCOD kunobatsira kutarisa kushanda zvakanaka kwekurapa, kuve nechokwadi chekuti mazinga ezvinosvibisa anodzikiswa kusvika pamazinga anogamuchirika.
BOD: Miedzo yeBOD inoita basa rakakosha mukuongorora kushanda kwebiological kurapwa maitiro, sezvo inoyera iyo chaiyo organic nyaya iripo mumvura.
Zvinhu Zvinokanganisa COD uye BOD Levels
- Tembiricha uye Mamiriro ekunze
- Mhando Yezvinosvibisa
- Kuvapo kweInhibitors
- Microbial Chiitiko
Mibvunzo Inowanzo bvunzwa (FAQs)
Ndeupi musiyano mukuru pakati peCOD neBOD?
Ose ari maviri COD neBOD anoyera kudiwa kweokisijeni mumvura, asi COD inosanganisira oxidation yezvese organic uye inorganic zvinhu, nepo BOD inotarisa chete pane organic zvinhu.
Sei COD ichikurumidza kuyera kupfuura BOD?
Miedzo yeCOD inotsamira pamakemikari oxidation, ayo anoburitsa nekukurumidza mhedzisiro, nepo BOD bvunzo dzichida kuparara kwechisikigo kweiyo organic zvinhu nema microorganisms, zvichitora mazuva akati wandei.
Makwiro eCOD neBOD anokanganisa sei hupenyu hwemumvura?
High COD mazinga anotungamira mukudzikira kweokisijeni yakanyungudika, zvichikanganisa hupenyu hwemumvura. Yakakwira BOD mazinga zvakare inopedza oxygen, zvichikonzera kukuvadza kuhove nezvimwe zvipenyu.
Ndeapi manyuko makuru eCOD neBOD mumvura yetsvina?
COD neBOD mumvura yetsvina zvinonyanya kubva mutsvina yemumba, inobuda mumaindasitiri, uye inoyerera yekurima ine organic uye inorganic zvinosvibisa.
Zvidyarwa zvekuchenesa mvura zvinoshandisa sei COD neBOD data?
Mishonga yekuchenesa mvura inoshandisa COD neBOD data kutarisa kushanda kwemaitiro avo ekurapa, kuve nechokwadi chokuti zvinosvibisa zvinoderedzwa kusvika kumazinga anogamuchirwa.
Pane here mirau yakatarwa yeCOD neBOD mazinga?
Ehe, mirau yezvakatipoteredza inoisa zviyero zvehuwandu hweCOD neBOD mazinga ekuchengetedza miviri yemvura uye kuchengetedza hutano hwakanaka.
Mhedziso
Kunzwisisa mutsauko uripo pakati peCOD neBOD kwakakosha pakuongorora kunaka kwemvura uye kutarisa kusvibiswa kwemazinga. COD inotipa tarisiro yakafara yekusvibiswa kwese, nepo BOD ichinanga kusvibiswa kwehupenyu. Maparamita ese ari maviri anotamba mabasa akakosha mukurapwa kwemvura yetsvina uye kuongorora kwezvakatipoteredza. Nekutevedzera zvimiro zvemitemo uye nekushandisa nzira dzekuyera dzakakwana, tinogona kutora matanho anodiwa kuchengetedza miviri yedu yemvura uye kuve neramangwana rakagadzikana.
