TheBOD mitachiridzwa chinoshandiswa kuona kusvibiswa kwehupenyu mumvura.BOD metres anoshandisa huwandu hweoxygen inopedzwa nezvipenyu kuputsa organic matter kuongorora kunaka kwemvura.
Nheyo yemamita eBOD yakavakirwa pamaitiro ekuora organic zvinosvibisa mumvura nemabhakitiriya uye nekudya oxygen.Kutanga, imwe chiyero chemuenzaniso inotorwa kubva mumuenzaniso wemvura kuti iongororwe, uye ipapo sampu inowedzerwa kubhodhoro rekuyeresa rine biological reagents, iro rine tsika dzebhakitiriya kana tupukanana tunogona kuputsa zvinosvibisa organic uye kupedza oxygen.
Tevere, bhodhoro rekuyedza rine sampuli uye biological reagents rinonamwa uye rinoiswa pane chaiyo tembiricha yekuisa.Munguva yekurima, organic zvinosvibisa zvakasvibiswa, zvichiperekedzwa nekuwedzera kwehuwandu hweokisijeni inopedzwa.Nekuyera iyo yakasara yakanyungudutswa yeokisijeni mubhodhoro mushure metsika, kukosha kweBOD mumucherechedzo wemvura inogona kuverengwa, iyo inoshandiswa kuongorora kusanganiswa kwezvakasvibiswa zvehupenyu uye mamiriro ehutano hwemvura mumvura yemvura.
Inogona kushandiswa kutarisa maitiro ekurapwa kwezvigadziriso zvetsvina uye kuongorora izvo organic zviri mumitumbi yemvura senge tsvina yemumba, tsvina yemumaindasitiri uye dhizaini yekurima.Nekuyera kukosha kweBOD, tinogona kutonga maitiro ekurapa kwetsvina uye chiyero chekusvibiswa kwemitumbi yemvura, uye kufanotaura mashandisirwo eokisijeni yebhayoloji mu ecosystem.Pamusoro pezvo, chiridzwa ichi chinogona zvakare kushandiswa kutarisa zvinoparadza kana zvine chepfu mumitumbi yemvura, ichipa chirevo chekuchengetedza zviwanikwa zvemvura uye nharaunda yezvakatipoteredza.
Iyo BOD mita ine mabhenefiti ekushandisa nyore, kuyera kuyerwa uye kurongeka kwepamusoro.Kuenzaniswa nedzimwe nzira dzekuyera, yakananga, ine mari uye yakavimbika.Nekudaro, pane zvimwe zvisingakwanisi mukushandiswa kwechiridzwa ichi, senge nguva yakareba yekuyera (kazhinji mazuva 5-7, kana 1-30 mazuva), uye zvinodikanwa zvakanyanya zvekugadzirisa chiridzwa uye biological reagent management.Pamusoro pezvo, sezvo maitiro ekutsunga akavakirwa pakuita kwebiology, mhedzisiro yacho inokanganiswa nemamiriro ekunze uye biological chiitiko, uye mamiriro ekuyedza anofanirwa kudzorwa zvakanyanya.
Kupfupisa, mita yeBOD chiridzwa chinoshandiswa kuyera organic pollutants mumvura.Inoongorora kunaka uye chiyero chekusvibiswa kwemvura nekuyera huwandu hweokisijeni inopedzwa kana organic zvinhu mumasampuli emvura zvaora.Inobata basa rakakosha mukutarisisa kunaka kwemvura uye kuchengetedza kwezvakatipoteredza, uye inopa data inobatsira uye referensi yekutsigira kutungamira kwezvakatipoteredza uye kuchengetedza zviwanikwa zvemvura.Nekufambira mberi kwesainzi uye tekinoroji, ndinotenda kuti mashandiro uye mashandisirwo enzvimbo dzechiridzwa ichi acharamba achiwedzera nekuvandudza.
Kukuvadza kweBOD yakawandisa kunoratidzwa zvakanyanya mune zvinotevera zvinhu:
1. Kushandiswa kweokisijeni yakanyungudutswa mumvura: Kuwedzerwa kweBOD kunowedzera kunowedzera kubereka kwehutachiona hweaerobic uye aerobic organisms, zvichiita kuti okisijeni iri mumvura ikurumidze kupedzwa, zvichiita kuti kufa kwezvisikwa zvemvura.
2. Kushatisa kwemhando yemvura: Kuberekana kwehuwandu hukuru hwema microorganisms anotora oxygen mumuviri wemvura kunopedza okisijeni yakanyungudika uye kugadzira kusvibiswa kweorganic muzvikamu zvayo zvehupenyu.Iyi ndiyo pfuma yekuzvinatsa yemuviri wemvura.Yakawandisa BOD inokonzeresa kuti mabhakitiriya eaerobic, aerobic protozoa, uye aerobic zvirimwa zvekuzvarwa zviwande muhuwandu, nekukurumidza kupedza oxygen, zvichikonzera kufa kwehove neshrimp, uye kuberekana kukuru kweanaerobic bacteria.
3. Inokanganisa kugona kwekuzvinatsa kwemuviri wemvura: Zviri mukati meokisijeni yakanyungudika mumuviri wemvura zvine hukama zvakanyanya nekugona kuzvinatsa kwemuviri wemvura.Kudzikira kweokisijeni yakanyungudika, ndiko kuderera kwekugona kuzvinatsa kwemuviri wemvura.
4. Kubudisa kunhuhwirira: Kuwedzeredza kweBOD kuchaita kuti muviri wemvura ubudise kunhuhwirira, izvo zvisingakanganisi hutano hwemvura chete, asiwo zvinopa ngozi kune zvakatipoteredza uye hutano hwevanhu.
5. Inokonzera mafungu matsvuku uye algae blooms: Yakawandisa BOD inotungamirira kune eutrophication yemitumbi yemvura, zvichiita kuti mafungu matsvuku uye algae blooms.Izvi zviitiko zvinoparadza kuenzana kwezvisikwa zvemumvura uye zvinounza njodzi kuhutano hwevanhu nemvura yekunwa.
Naizvozvo, yakawandisa BOD ndiyo inonyanya kukosha yemhando yekusvibiswa kwemvura parameter, iyo inogona kuratidza zvisina kunanga zviri mukati biodegradable organic zvinhu mumvura.Kana tsvina ine BOD yakawandisa ikaiswa mumvura yechisikigo yakaita senzizi nemakungwa, haingokonzere kufa kwezvipenyu zviri mumvura, asi zvakare kukonzera chepfu chisingaperi mushure mekuunganidzwa mucheni yekudya uye kupinda mumuviri wemunhu, zvichikanganisa nervous system uye kukuvadza kushanda kwechiropa.
Lianhua's BOD chiridzwa parizvino chiri kushandiswa zvakanyanya muChina neSoutheast Asia kuona BOD mumvura.Icho chiridzwa chiri nyore kushanda uye chinoshandisa mashoma reagents, kuderedza mashandiro ekuita uye kusvibiswa kwechipiri.Yakakodzera kune ese mafambiro ehupenyu, mayunivhesiti, uye makambani ekutarisa zvakatipoteredza.uye zvirongwa zvehurumende zvekudzora kusvibiswa kwemvura.
