UMUBIRI (Biochemical Oxygen Demand), ukurikije ibisobanuro byigihugu, BOD bivuga ibinyabuzima
Oxygene isabwa bivuga ogisijeni yashonze ikoreshwa na mikorobe mu binyabuzima bya chimique yo kubora ibintu bimwe na bimwe bya okiside mu mazi mu bihe byagenwe.
Ingaruka za BOD: Imyanda yo mu ngo n’amazi mabi y’inganda arimo ubwinshi bwibintu bitandukanye kama.Iyo ibyo bintu kama bibora mumazi nyuma yo kwanduza amazi, bakoresha ogisijeni nyinshi yashonze, bityo bikabangamira uburinganire bwa ogisijeni mumazi, bikangiza ubwiza bwamazi, bikanatera urupfu rwamafi nibindi binyabuzima byo mumazi kubera hypoxia .Ibimera kama biri mumibiri yamazi biragoye kandi biragoye kumenya kuri buri kintu.Abantu bakunze gukoresha ogisijeni ikoreshwa n’ibinyabuzima mu mazi mu bihe bimwe na bimwe kugira ngo bagaragaze mu buryo butaziguye ibirimo ibinyabuzima biri mu mazi, kandi umwuka wa ogisijeni wa Biochemiki ni kimwe mu bimenyetso byingenzi.Irerekana kandi ibinyabuzima byangiza ibinyabuzima mumazi mabi.
Niki BOD5: (BOD5) bivuga ingano ya ogisijeni yashonze ikoreshwa mugihe icyitegererezo cyashyizwe ahantu hijimye kuri (20 ± 1) ℃ muminsi 5 ± amasaha 4.
Microbial electrode ni sensor ihuza tekinoroji ya mikorobe nubuhanga bwo kumenya amashanyarazi.Igizwe ahanini na electrode ya elegitoronike yashonze hamwe na firime ya mikorobe idafite imbaraga zifatanije cyane nubuso bwayo buhumeka.Ihame ryo gusubiza ibintu BOD ni uko iyo byinjijwe muri substrate idafite ibintu bya B0D ku bushyuhe buhoraho no gushonga kwa ogisijeni, bitewe n’ibikorwa bimwe na bimwe by’ubuhumekero bya mikorobe, molekile ya ogisijeni yashonze muri substrate ikwirakwira muri electrode ya ogisijeni binyuze mikorobe ya membrane ku gipimo runaka, na electrode ya mikorobe isohora ibintu bihoraho;Niba ibintu bya BOD byongewe kumuti wo hasi, molekile yibintu izakwirakwira muri mikorobe hamwe na molekile ya ogisijeni.Kuberako microorganisme muri membrane izahindura Anabolism ibintu BOD ikarya ogisijeni, molekile ya ogisijeni yinjira muri electrode ya ogisijeni izagabanuka, ni ukuvuga ko igipimo cyo gukwirakwiza kizagabanuka, umusaruro wa electrode uzagabanuka, kandi uzagwa ku giciro gishya gihamye muminota mike.Muburyo bukwiye bwo kwibanda kuri BOD, hariho umurongo ugaragara hagati yo kugabanuka kwa electrode isohoka nubu hamwe na BOD, mugihe hariho isano iri hagati yibitekerezo bya BOD nagaciro ka BOD.Kubwibyo, ukurikije igabanuka ryubu, BOD yurugero rwamazi yapimwe irashobora kugenwa.
LH-BODK81 Biologiya Himiki ya ogisijene ikenera BOD ya mikorobe ya sensor igerageza byihuse, ugereranije nuburyo gakondo bwo gupima BOD, ubu bwoko bushya bwa sensor optique bufite ibyiza byinshi.Ubwa mbere, uburyo bwa gakondo bwo gupima BOD busaba inzira ndende yo guhinga, mubisanzwe bifata iminsi 5-7, mugihe ibyuma bishya bifata iminota mike yo kurangiza gupima.Icya kabiri, uburyo bwa gakondo bwo gupima busaba umubare munini wa reagent ya chimique nibikoresho byibirahure, mugihe sensor nshya idasaba reagent cyangwa ibikoresho, kugabanya ibiciro byubushakashatsi hamwe nishoramari ryabakozi.Byongeye kandi, uburyo bwa gakondo bwo gupima BOD bushobora kwibasirwa n’ibidukikije nkubushyuhe n’umucyo, mugihe ibyuma bishya bishobora gupima ahantu hatandukanye kandi bigasubiza vuba impinduka.
Kubwibyo, ubu bwoko bushya bwa optique sensor ifite ibyifuzo byinshi.Usibye gukoreshwa mu rwego rwo kugenzura ubuziranenge bw’amazi, iyi sensor irashobora kandi gukoreshwa mubice bitandukanye nkibiryo, ubuvuzi, kurengera ibidukikije, hamwe no gutahura ibintu kama mu myigishirize ya laboratoire.
