NikiCod Bod isesengura?
Cod (imiti yimiti) hamwe na bod (ibinyabuzima bya ogisijeni) ni ingamba ebyiri za ogisijeni zisabwa kumena ibintu ngengane mumazi. Cod ni igipimo cya ogisijeni gisabwa kugirango ugabanye ibintu kama mvuwe, mugihe umukara ari igipimo cya ogisijeni gisabwa kugirango ucike ibinyabuzima birinze ibinyabuzima, ukoresheje mikorobe.
Isesengura / bod isesengura nigikoresho gikoreshwa mugupima code n'umukara w'icyitegererezo cy'amazi. Izisesengura ikora mugupima ibitekerezo bya ogisijeni mumazi mbere na nyuma yibintu kama byemerewe gusenyuka. Itandukaniro muri ogisijeni ryibanda mbere na nyuma yo gusenyuka bikoreshwa mukubara code cyangwa umunwa wicyitegererezo.
Ibipimo bya Cod nibipimo byingenzi byerekana ubwiza bwamazi kandi bikunze gukoreshwa mugukurikirana imikorere yububiko bwamazi hamwe nibindi bya sisitemu yo kuvura amazi. Bakoreshwa kandi kugirango basuzume ingaruka zishobora gusohora amazi adahungabana mumibiri yabamazi, nkinzego zinini mumazi zirashobora kugabanya ogisijeni zirimo guhinduka.
Nigute bod na code zapimwe?
Hariho uburyo bwinshi bushobora gukoreshwa mugupima amavuta (ibinyabuzima bya ogisijeni) na cod (ibisabwa bya ogisijeni (imiti) mumazi. Hano hari incamake yuburyo bubiri bwingenzi:
Uburyo bwo Kwirukana: Muburyo bwo Kwirukana, Umubumbe uzwi wamazi uvangwa namazi runaka yo kwikuramo, ikubiyemo inzego nkeya yibinyabuzima. Icyitegererezo cya kabiri gihita gishishwa mugihe runaka (mubisanzwe iminsi 5) ku bushyuhe bugenzurwa (mubisanzwe 20 ° C). Kwibanda kuri ogisijeni muri sample bipimwa mbere na nyuma ya incubation. Itandukaniro muri ogisijeni ryibanda mbere na nyuma ya incubation ikoreshwa mukubara umunwa wicyitegererezo.
Gupima code, hakurikiraho inzira isa nayo irakurikizwa, ariko icyitegererezo cyavuwe hamwe nigituba cya okiside ya chimique (nka potasiyumu diichromate) aho kuba icumu. Kwibanda kuri ogisijeni bimaze kubijyanye na chimique bikoreshwa mugukaba code yicyitegererezo.
Uburyo bwa Respirometer: Muburyo bwa Respirometero, kontineri ifunze (bita respirometero) ikoreshwa mugupima ihagarikwa rya ogisijeni mugihe basenya ibintu ngengamizi mumazi. Kwibanda kuri ogisijeni muri respirometero bipimirwa mugihe runaka (mubisanzwe iminsi 5) ku bushyuhe bugenzurwa (mubisanzwe 20 ° C). Umunwa wicyitegererezo ubarwa ukurikije igipimo cyerekana ko ibitekerezo bya ogisijeni bigabanuka mugihe.
Uburyo bwoguha hamwe nuburyo bwa Respirometero ni uburyo bukoreshwa kwisi yose kugirango apime amavuta kandi akodeshwa mumazi.
Bord na Cod ntarengwa?
Bod (ibinyabuzima bya ogisijeni) na cod (ibisabwa bya ogisijeni (imiti ya oxygen) ni ingamba za ogisijeni zisabwa kumena ibintu kama mu mazi. Urwego rwa Bod na Cod rushobora gukoreshwa mugusuzuma ubwiza bwamazi hamwe ningaruka zishobora gusohora amazi hasi mumazi.
Bord na Cod imipaka ni amahame akoreshwa mugupima urwego rwa bod na code mumazi. Iyi mipaka mubisanzwe ishyirwaho ninzego zishinzwe kugenzura kandi zishingiye ku nzego zemewe z'ibinyabuzima mumazi atazagira ingaruka mbi kubidukikije. Imipaka ya Bor na Cod isanzwe igaragazwa muri miligram ya ogisijeni kuri litiro y'amazi (mg / l).
Imipaka ya Bod ikoreshwa mu gukoresha umubare wibintu kama mumazi asezerewe mumazi make, nkinzuzi n'ibiyaga. Urwego rwo hejuru rwa BOD mumazi rushobora kugabanya ibikubiye muri ogisijeni mu mazi no kugirira nabi ubuzima bwo kurya. Nkigisubizo, ibihingwa byamazi birasabwa kuzuza imipaka yihariye mugihe isohotse efflient yabo.
Imipaka ya Cod ikoreshwa mugupima urwego rwibintu kama nibindi byanduye mumazi yinganda. Urwego rwo hejuru rwa code mumazi rushobora kwerekana ko hariho ibintu byuburozi cyangwa byangiza, kandi birashobora no kugabanya ogisijeni ibikubiye mumazi no kugirira nabi ubuzima bwo kurya. Ibikoresho byinganda mubisanzwe bisabwa kuzuza imipaka yihariye mugihe isohotse amazi yacyo.
Muri rusange, imipaka ya Cod na Cod nibikoresho byingenzi byo kurengera ibidukikije no kwemeza ubwiza bwamazi mumazi.
