Ibinyabuzima bya Oxygene isaba VS Ibisabwa bya Oxygene

Niki Oxygene ya Biochemiki isaba (BOD)?

Ibinyabuzima bya Oxygene ikenerwa (BOD) Bizwi kandi nka ogisijeni ikenerwa na biohimiki. Nibipimo byuzuye byerekana ibiri mubintu bisaba ogisijeni nkibintu kama mumazi. Iyo ibinyabuzima bikubiye mu mazi bihuye n’ikirere, byangirika na mikorobe yo mu kirere, kandi urugero rwa ogisijeni isabwa kugira ngo ikorwe mu buryo budasanzwe cyangwa gazi bita ogisijeni ikomoka ku binyabuzima, igaragarira muri ppm cyangwa mg / L. Uko agaciro kangana, niko umwanda uhumanya mu mazi n’umwanda ukabije. Mubyukuri, igihe cyo kubora burundu ibintu kama kiratandukanye nubwoko bwacyo n'ubwinshi, ubwoko n'ubwinshi bwa mikorobe, hamwe na kamere y'amazi. Bikunze gufata iminsi mirongo cyangwa amagana kugirango okiside rwose kandi ibore. Byongeye kandi, Rimwe na rimwe, bitewe n’ibyuma biremereye n’ibintu bifite ubumara mu mazi, ibikorwa bya mikorobe birabangamiwe ndetse bikicwa. Kubwibyo, biragoye gupima UMUBIRI neza. Kugirango ugabanye igihe, iminsi 5 ya ogisijeni ikenerwa (BOD5) muri rusange ikoreshwa nkigipimo fatizo cyo kugereranya imyanda ihumanya amazi. BOD5 ihwanye na 70% yo gukoresha ogisijeni kugirango ibore neza. Muri rusange, inzuzi zifite BOD5 munsi ya 4ppm zishobora kuvugwa ko zidafite umwanda.

Nigute ushobora gupima ogisijeni ya Biochemiki?

Igikoresho cyoroshye-gukora BOD yo kumenya ni ingenzi cyane mugushakisha ubuziranenge bwamazi. Igikoresho cya BOD5 cya Lianhua gikoresha uburyo butandukanye bwa mercure (manometric), bushobora gupima amazi arimo bagiteri utiriwe wongera imiti, kandi ibisubizo birashobora gucapwa mu buryo bwikora. Kuyobora ikoranabuhanga ryemewe.

Ikibazo cya Oxygene ikenewe ni iki (COD)?

Umwuka wa ogisijeni ukenewe (COD) ni urugero rwa ogisijeni ikenerwa kugira ngo ihumanye imyanda ihumanya ndetse na bimwe bigabanya ibintu biri mu mazi mu bihe bimwe na bimwe hamwe na okiside (nka potasiyumu dichromate cyangwa potasiyumu permanganate), bigaragarira muri miligarama ya ogisijeni ikoreshwa kuri litiro y'icyitegererezo cy'amazi umubare wavuzwe. COD nikimenyetso cyingenzi gikoreshwa mugusuzuma ubwiza bwamazi. Umwuka wa ogisijeni ukenewe ufite ibiranga uburyo bworoshye kandi bwihuse bwo kugena. Chromate ya Potasiyumu, oxyde oxyde, irashobora okiside rwose ibintu kama mumazi, kandi irashobora no guhinduranya ibindi bintu bigabanya. Okiside potasiyumu permanganate irashobora gusa okiside hafi 60% yibintu kama. Nta na bumwe muri ubwo buryo bubiri bushobora kwerekana uko ibintu byifashe mu iyangirika ry’imyanda ihumanya y’amazi, kubera ko nta na kimwe muri byo kigaragaza ingano y’ibinyabuzima mikorobe ishobora kwangiza. Kubwibyo, ogisijeni ikomoka kuri biohimiki ikoreshwa cyane mukwiga ubwiza bwamazi yanduye nibintu kama.

Kugeza ubu, kumenya COD biramenyerewe cyane mu gutunganya amazi, kandi birasabwa ninganda, inganda zanduye, amakomine, inzuzi n’inganda. Ikoreshwa rya COD ya Lianhua irashobora kubona vuba ibisubizo nyabyo muminota 20 kandi irakoreshwa cyane.
