Ibipimo bya COD na BOD birangana?

Oya, COD na BOD ntabwo ari igitekerezo kimwe; ariko, bafitanye isano ya hafi.
Byombi nibintu byingenzi bikoreshwa mugusuzuma ubwinshi bwimyanda ihumanya mumazi, nubwo bitandukanye mubijyanye namahame yo gupima nubunini.

Ibikurikira biratanga ibisobanuro birambuye kubitandukaniro ryabo nubusabane:

1. Ibisabwa bya Oxygene ya Himiki (COD)

· Igisobanuro: COD bivuga ingano ya ogisijeni ikenerwa kugirango ihindurwe mu buryo bwa chimique ibintu byose kama mumazi ukoresheje imiti ikomeye ya okiside, mubisanzwe potasiyumu dichromate, mubihe bya acide cyane. Igaragarira muri miligarama ya ogisijeni kuri litiro (mg / L).
· Ihame: Okiside ya chimique. Ibintu kama bihinduka okiside rwose binyuze mumashanyarazi mugihe cy'ubushyuhe bwo hejuru (hafi amasaha 2).
· Ibintu byapimwe: COD ipima hafi ibinyabuzima byose, harimo ibinyabuzima bishobora kwangirika ndetse n'ibidashobora kwangirika.

Ibiranga:
· Ibipimo byihuse: Ibisubizo birashobora kuboneka mugihe cyamasaha 2-3.
· Urwego rwagutse rwo gupima: Indangagaciro za COD muri rusange zirenga agaciro ka BOD kuko uburyo bubara ibintu byose bya chimique oxydeize.
· Kubura umwihariko: COD ntishobora gutandukanya ibinyabuzima byangirika nibidashobora kwangirika.

2.Biochemiki ya Oxygene isabwa (BOD)

· Igisobanuro: BOD bivuga ingano ya ogisijeni yashonze ikoreshwa na mikorobe mugihe cyo kubora ibinyabuzima byangirika mumazi mubihe byihariye (mubisanzwe 20 ° C muminsi 5, byitwa BOD₅). Bigaragarira kandi muri miligarama kuri litiro (mg / L).
· Ihame: Okiside yibinyabuzima. Kwangirika kw'ibinyabuzima na mikorobe yo mu kirere bigereranya inzira yo kwisukura isanzwe iboneka mu mazi.
· Ibintu byapimwe: BOD ipima gusa igice cyibintu kama bishobora kwangirika mubinyabuzima.

Ibiranga:
· Igihe kirekire cyo gupima: Ikizamini gisanzwe ni iminsi 5 (BOD₅).
· Yerekana imiterere karemano: Itanga ubushishozi mubyukuri ubushobozi bwo gukoresha ogisijeni yibintu kama mubidukikije.
· Umwihariko: BOD isubiza gusa ibinyabuzima bishobora kwangirika.

3. Guhuza no Gushyira mu bikorwa

Nubwo bitandukanye, COD na BOD bikunze gusesengurwa hamwe kandi bigira uruhare runini mugusuzuma ubuziranenge bwamazi no gutunganya amazi mabi:

1) Gusuzuma ibinyabuzima:
Ikigereranyo cya BOD / COD gikunze gukoreshwa mugusuzuma uburyo bushoboka bwo kuvura ibinyabuzima (urugero, inzira ya siliveri ikora).
· UMUBIRI / COD> 0.3: Yerekana ibinyabuzima byiza, byerekana ko kuvura ibinyabuzima bikwiye.
· UMUBIRI / KODE <0.3: Yerekana igice kinini cyibintu bivangwa n’ibinyabuzima byangirika kandi bidafite ubuzima bubi. Mu bihe nk'ibi, uburyo bwo kwitegura (urugero, okiside igezweho cyangwa imyanda ya coagulation) birashobora gusabwa kugirango ibinyabuzima bigabanuke, cyangwa ubundi buryo bwo kuvura umubiri-imiti bushobora gukenerwa.

2) Ibisabwa:
· UMUBIRI: Byakoreshejwe cyane cyane mugusuzuma ingaruka z’ibidukikije ziterwa n’amazi y’amazi ku mazi asanzwe, cyane cyane mu bijyanye no kugabanuka kwa ogisijeni n’ubushobozi bwayo bwo guhitana ubuzima bw’amazi.
· COD: Ikoreshwa cyane mugukurikirana byihuse imitwaro y’imyanda ihumanya y’inganda, cyane cyane iyo amazi y’amazi arimo ibintu bifite ubumara cyangwa butabora. Bitewe nubushobozi bwayo bwo gupima byihuse, COD ikoreshwa kenshi mugukurikirana igihe no kugenzura ibikorwa muri sisitemu yo gutunganya amazi mabi.

Inshamake y'ibyingenzi bitandukanye

Ibiranga	COD (Imiti ya Oxygene ikenewe)	UMUBIRI (Ibinyabuzima bya Oxygene isabwa)
Ihame	Okiside ya shimi	Okiside yibinyabuzima (ibikorwa bya mikorobe)
Oxidant	Okiside ikomeye ya chimique (urugero, potasiyumu dichromate)	Ibinyabuzima byo mu kirere
Ingano yo gupimwa	Harimo ibintu byose bya chimique oxydeize (harimo na biodegradable)	Gusa ibinyabuzima bishobora kwangirika
Igihe cyizamini	Mugufi (amasaha 2-3)	Murebure (iminsi 5 cyangwa irenga)
Umubano mubi	KOD ≥ UMUBIRI	UMUBIRI ≤ KOD

Umwanzuro:

COD na BOD ni ibipimo byuzuzanya mu gusuzuma umwanda kama mu mazi aho kuba ingamba zingana. COD irashobora gufatwa nk "" inyigisho nini ya ogisijeni ikenewe "yibintu byose bihari, mugihe BOD igaragaza" ubushobozi bwa ogisijeni nyayo "mubihe bisanzwe.

Gusobanukirwa itandukaniro nubusabane hagati ya COD na BOD ningirakamaro mugushushanya uburyo bwiza bwo gutunganya amazi mabi, gusuzuma ubwiza bwamazi, no gushyiraho ibipimo bikwiye.

Shanghai Boqu Instrument Co., Ltd kabuhariwe mu gutanga urwego rwuzuye rwa COD na BOD isesengura amazi meza kumurongo. Ibikoresho byacu byisesengura byubwenge bifasha kugenzura igihe-nyacyo no kugenzura neza, guhererekanya amakuru mu buryo bwikora, no gucunga ibicu, bityo bikorohereza ishyirwaho ryiza rya sisitemu yo gukurikirana amazi ya kure kandi yubwenge.
