ChiiCod bod analyzer?
COD (Chemical Oxygen inodiwa) uye BOD (Biological oxygen inodikanwa) matanho maviri ehuwandu hweokisijeni inodikanwa kuputsa organic nyaya mumvura. COD chiyero cheokisijeni chinodiwa kuputsa organic zvinhu zvemakemikari, nepo BOD chiyero cheokisijeni chinodiwa kuputsa organic zvinhu biologically, uchishandisa hutachiona.
A COD / BOD ANCYGER chishandiso chinoshandiswa kuyera cod uye bhodhi yemuenzaniso wemvura. Aya anoongorora anoshanda nekuyera kusunganidzwa kweokisijeni mumuenzaniso wemvura zvisati zvaitika uye mushure meiyo organic nyaya yabvumidzwa kuputsa. Musiyano wejasi rekusangana kweOxygen zvisati zvaitika uye mushure mekuputsa maitiro uchishandisa kuverenga cod kana bhodhi yemuenzaniso.
Cod uye Bod zviyero zvakakosha zviratidzo zvemhando yemvura uye zvinowanzoshandiswa kuongorora kushanda kwemarara ekurapa ekurapa uye mamwe maratidziro emvura. Ivo zvakare vanoshandiswawo kuongorora maitiro anogona kuendesa kumvura mumitumbi yemvura, semazinga makuru echinhu che organic mumvura anogona kuderedza oksijeni yemvura uye kukuvadza hupenyu hwemvura.
Bod uye cod yakayerwa sei?
Kune nzira dzinoverengeka dzinogona kushandiswa kuyera bod (biological oxygen inodiwa) uye cod (makemikari okisijeni inodiwa) mumvura. Heino kuongorora kupfupi kwenzira mbiri huru:
Nzira yeDuliution: Munzira yeDuliation, iyo vhoriyamu inozivikanwa yemvura inoiswa pamwe neyakaenzana kwemvura yemvura, iyo ine huwandu hwakanyanya hwenzvimbo ye organic. Iyo sampu yakakwenenzverwa inobva yavezwa kwenguva yakatarwa yenguva (kazhinji mazuva mashanu) pakudziya kwakadzorwa (kazhinji 20 ° C). Iko kusvinura kweokisijeni mumuenzaniso kunoyerwa kare uye mushure mekunge mubatanidzwa. Musiyano wejasi rekusangana kweOxygen zvisati zvaitika uye mushure mekunge mugumo wechibereko unoshandiswa kuverenga bhodhi yemuenzaniso.
Kuyera cod, maitiro akafanana anoteverwa, asi muenzaniso unobatwa nemakemikari oxidizing mumiririri (senge potasasium dichromate) pane kuti ishandiswe. Iko kusunganidzwa kweokisijeni kunopedzwa nekuita kwemakemikari kunoshandiswa kuverenga chikamu chemuenzaniso.
Respirometer Nzira: Mune nzira yekufema, mudziyo wakasungwa (anonzi respirometer) rinoshandiswa kuyera oksijasi rekushandisa microorgs pavanopwanya nyaya organic mumuenzaniso wemvura. Iyo oksijeni yekushambadzira muRespirometer inoyerwa pane imwe nguva yenguva (kazhinji mazuva mashanu) pakudziya kwekudziya (kazhinji 20 ° C). Iyo bhodhi yemuenzaniso inoverengwa zvichienderana nehuwandu apo iyo oksijeni yekudzikira nekufamba kwenguva.
Zvese zviri zviviri nzira yekudhira uye nzira yekufema yakanyorwa nzira dzinoshandiswa pasi rese kuti dziyere uye cod mumvura.
Chii chinonzi bod uye cod muganho?
Bod (biological oxygen inodiwa) uye cod (makemikari okisijeni inodiwa) matanho ehuwandu hweokisijeni inodiwa kuputsa organic nyaya mumvura. Bod uye cod mazinga anogona kushandiswa kuongorora mhando yemvura uye maitiro anogona kukanganisa emvura yakashata mumitumbi yemvura.
Bod uye cod miganhu zviyero zvinoshandiswa kudzora mazinga eBod uye cod mumvura. Iyi miganhu inowanzoiswa nemasangano ekuzvidzora uye anovakirwa pamazinga anogamuchirika enyaya mune mvura iyo isingazove neisina kukanganisa nharaunda. Bod uye cod miganhu inowanzo kuratidzwa mumamirimita eokisijeni pane litre yemvura (mg / l).
Bod miganhu inoshandiswa kutungamira huwandu hwenzvimbo yeganda mumatanda anotambisa mumitumbi yemvura, senge nzizi uye nyanza. Yakakwira mwero weBod mumvura inogona kuderedza okisijeni yemvura uye kukuvadza hupenyu hwemvura. Nekuda kweizvozvo, zvirimwa zvekurapa zvekurapa zvinodikanwa kuti usangane zvakananga miganhu yakagadzirirwa paunenge uchidzora fungidziro yavo.
Cod miganhu inoshandiswa kudzora mazinga echinhu che organic uye zvimwe zvinosvibisa muhomwe yemasipita. Nhamba dzakakwirira dze cod mumvura dzinogona kuratidza kuvapo kwezvinhu zvine chepfu kana zvinokuvadza, uye zvinogona zvakare kuderedza oksijeni yemvura uye kukuvadza hupenyu hwemumvura. Zvivakwa zveindasitiri zvinowanzo kuve zvichidikanwa kusangana zvakananga cod miganhu kana zvichikanganisa yavo marara.
Zvakazara, Bod uye cod miganhu inonyanya kukosha zvekudzivirira zvakatipoteredza uye kuve nemhando yemvura mumiviri yakasikwa yemvura.
