Kumenyekanisha metero ya ogisijeni yamenetse

Umwuka wa ogisijeni ushonga bivuga urugero rwa ogisijeni yashonze mu mazi, ubusanzwe yandikwa nka DO, igaragarira muri miligarama ya ogisijeni kuri litiro y'amazi (muri mg / L cyangwa ppm).Ibinyabuzima bimwe na bimwe byangiza ibinyabuzima bigizwe na bagiteri zo mu kirere, zikoresha ogisijeni yashonze mu mazi, kandi umwuka wa ogisijeni ushonga ntushobora kuzuzwa mu gihe.Bagiteri ya anaerobic mumubiri wamazi izagwira vuba, kandi ibinyabuzima bizahindura umubiri wamazi kubera ruswa.impumuro.Ingano ya ogisijeni yashonze mumazi nikimenyetso cyo gupima ubushobozi bwo kwisukura bwumubiri wamazi.Umwuka wa ogisijeni ushonga mu mazi urakoreshwa, kandi bisaba igihe gito kugirango ugaruke uko byari bimeze mbere, byerekana ko umubiri wamazi ufite imbaraga zo kwisukura, cyangwa ko umwanda w’amazi udakomeye.Bitabaye ibyo, bivuze ko umubiri wamazi wanduye cyane, ubushobozi bwo kwisukura bugira intege nke, cyangwa nubushobozi bwo kwisukura bwatakaye.Ifitanye isano rya bugufi nigitutu cyigice cya ogisijeni mukirere, umuvuduko wikirere, ubushyuhe bwamazi nubwiza bwamazi.

1.Ubuhinzi: kwemeza ibyifuzo byubuhumekero bwibicuruzwa byo mu mazi, kugenzura igihe nyacyo cyibintu bya ogisijeni, gutabaza byikora, okisijeni yikora nindi mirimo

2.Gukurikirana amazi meza kumazi karemano: Menya urugero rwumwanda nubushobozi bwo kwisukura bwamazi, kandi wirinde kwanduza ibinyabuzima nka eutrophasi yumubiri wamazi.

3. Gutunganya imyanda, ibipimo byo kugenzura: ikigega cya anaerobic, ikigega cya aerobic, ikigega cya aeration nibindi bipimo bikoreshwa mukugenzura ingaruka zo gutunganya amazi.

4. Kugenzura kwangirika kwibikoresho byicyuma mumiyoboro itanga amazi: Mubisanzwe, ibyuma bifata intera ya ppb (ug / L) bikoreshwa mugucunga umuyoboro kugirango ugere kuri ogisijeni zeru kugirango wirinde ingese.Bikunze gukoreshwa mumashanyarazi nibikoresho byo guteka.

Kugeza ubu, metero ya ogisijeni ikunze gushonga ku isoko ifite amahame abiri yo gupima: uburyo bwa membrane nuburyo bwa fluorescence.None ni irihe tandukaniro riri hagati yombi?

1. Uburyo bwa Membrane (buzwi kandi nkuburyo bwa polarography, uburyo bwumuvuduko uhoraho)
Uburyo bwa membrane bukoresha amahame ya electrochemic.Igice kimwe cya kabiri cyakoreshejwe mugutandukanya platine cathode, anode ya silver, na electrolyte hanze.Mubisanzwe, cathode iri hafi guhura niyi firime.Oxygene ikwirakwizwa muri membrane ku kigereranyo kijyanye n'umuvuduko wacyo.Iyo umuvuduko mwinshi wa ogisijeni, niko ogisijeni izanyura muri membrane.Iyo umwuka wa ogisijeni ushonga uhora winjira muri membrane hanyuma ukinjira mu cyuho, bigabanuka kuri cathode kugirango bitange umuyaga.Uyu muyoboro uhwanye neza na ogisijeni yashonze.Igice cya metero gikora uburyo bwo guhindura ibintu byapimwe mubice byibanda.

2. Fluorescence
Probe ya fluorescent ifite isoko-yumucyo itanga urumuri rwubururu kandi ikamurikira urwego rwa fluorescent.Ibintu bya fluorescent bitanga urumuri rutukura nyuma yo kwishima.Kubera ko molekile ya ogisijeni ishobora gutwara ingufu (ingaruka zo kuzimya), igihe nuburemere bwurumuri rutukura rwishimye bifitanye isano na molekile ya ogisijeni.Kwibandaho biringaniye.Mugupima itandukaniro ryicyiciro hagati yumucyo utukura wishimye numucyo werekana, ukabigereranya nagaciro kerekana imbere, ubunini bwa molekile ya ogisijeni irashobora kubarwa.Nta ogisijeni ikoreshwa mugihe cyo gupima, amakuru arahamye, imikorere irizewe, kandi ntakabuza.

Reka tubisesengure kuri buri wese uhereye kumikoreshereze:
1. Mugihe ukoresheje electrode ya polarografiya, shyushya byibuze iminota 15-30 mbere ya kalibrasi cyangwa gupima.
2. Bitewe no gukoresha ogisijeni na electrode, kwibumbira hamwe kwa ogisijeni hejuru yubushakashatsi bizahita bigabanuka, bityo rero ni ngombwa kubyutsa igisubizo mugihe cyo gupima!Muyandi magambo, kubera ko ibirimo ogisijeni bipimwa no gukoresha ogisijeni, habaho ikosa ritunganijwe.
3. Bitewe niterambere ryimikorere ya electrochemic, intumbero ya electrolyte ihora ikoreshwa, birakenewe rero kongeramo electrolyte buri gihe kugirango tumenye neza.Kugirango umenye neza ko nta bubyimba buri muri electrolyte ya membrane, birasabwa gukuramo ibyumba byose byamazi mugihe ushyizeho umwuka wumutwe.
4. Nyuma ya buri electrolyte imaze kongerwamo, hasabwa uruziga rushya rwibikorwa bya kalibrasi (mubisanzwe kalibrasi ya zeru mu mazi adafite ogisijeni na kalibrasi yo mu kirere), hanyuma niyo hakoreshwa ibikoresho byishyurwa ryubushyuhe bwikora, bigomba kuba hafi Kuri Nibyiza guhinduranya electrode kubushyuhe bwicyitegererezo.
5. Nta bubyimba bugomba gusigara hejuru ya kimwe cya kabiri cyinjira mugihe cyo gupima, bitabaye ibyo bizasoma ibibyimba nkicyitegererezo cyuzuye ogisijeni.Ntabwo byemewe kuyikoresha muri tank ya aeration.
6. Bitewe nimpamvu zitunganijwe, umutwe wa membrane uroroshye cyane, byoroshye gucengera muburyo runaka bubora, kandi ufite ubuzima buke.Nibintu biribwa.Niba ibyangiritse byangiritse, bigomba gusimburwa.

Kurangiza, uburyo bwa membrane ni uko ikosa ryukuri rikunda gutandukana, igihe cyo kubungabunga ni gito, kandi imikorere iraruhije!
Tuvuge iki ku buryo bwa fluorescence?Bitewe nihame ryumubiri, ogisijeni ikoreshwa gusa nka catalizator mugihe cyo gupima, bityo inzira yo gupima ntisanzwe ivanze hanze!Byinshi-bisobanutse neza, kubungabunga-ubusa, hamwe nubuziranenge-bwiza busigara butarebwa mumyaka 1-2 nyuma yo kwishyiriraho.Uburyo bwa fluorescence mubyukuri nta nenge bufite?Birumvikana ko hariho!
