ʻO BOD (Biochemical Oxygen Demand), e like me ka wehewehe maʻamau o ke aupuni, pili ka BOD i ka biochemical.
ʻO ke koi o ka oxygen e pili ana i ka oxygen dissolved i hoʻopau ʻia e nā microorganisms i ke kaʻina biochemical Chemical o ka decomposing i kekahi mau mea oxidizable i ka wai ma lalo o nā kūlana i kuhikuhi ʻia.
Ka hopena o ka BOD: Loaʻa i ka wai hoʻoheheʻe hale a me ka wai ʻino ʻoihana ka nui o nā pūhui organik like ʻole. Ke hoʻoheheʻe ʻia kēia mau mea ola i loko o ka wai ma hope o ka hoʻohaumia ʻana i ka wai, ʻai lākou i ka nui o ka oxygen i hoʻoheheʻe ʻia, a laila e hoʻopau i ke koena o ka oxygen i loko o ka wai, e hōʻemi ana i ka maikaʻi o ka wai, a make i nā iʻa a me nā mea ola wai ʻē aʻe ma muli o ka hypoxia. . He paʻakikī a paʻakikī ka hoʻoholo ʻana o nā mea hoʻohui i loko o nā kino wai. Hoʻohana pinepine ka poʻe i ka oxygen i hoʻopau ʻia e ka mea ola i loko o ka wai ma lalo o kekahi mau kūlana e hōʻike pololei ʻole i ka ʻike o ka mea organik i loko o ka wai, a ʻo ke koi ʻo Biochemical oxygen kekahi o ia mau hōʻailona koʻikoʻi. Hōʻike pū ia i ka biodegradability o nā pūhui organik i ka wai ʻino.
He aha ka BOD5: (BOD5) e pili ana i ka nui o ka oxygen dissolved i hoʻopau ʻia ke hoʻomoʻa ʻia ka hāpana ma kahi pouli ma (20 ± 1) ℃ no 5 mau lā ± 4 hola.
ʻO Microbial electrode kahi mea ʻike e hoʻohui i ka ʻenehana microbial me ka ʻenehana ʻike electrochemical. Loaʻa ia i kahi electrode oxygen i hoʻoheheʻe ʻia a me kahi kiʻiʻoniʻoni microbial i hoʻopaʻa paʻa ʻia i kona ʻili membrane breathable. ʻO ke kumu o ka pane ʻana i nā mea BOD ʻo ia ke hoʻokomo ʻia i loko o kahi substrate me ka ʻole o nā mea B0D i ka mahana mau a me ka hoʻoheheʻe ʻana o ka oxygen, ma muli o kekahi hana hanu o nā microorganisms, hoʻoheheʻe ʻia nā molekala oxygen i loko o ka substrate i loko o ka electrode oxygen. ka microbial membrane i kekahi manawa, a me ka microbial electrode e hoʻopuka i kahi ʻano paʻa; Inā hoʻohui ʻia ka mea BOD i ka hopena o lalo, e laha ka mole o ka mea i loko o ka membrane microbial me ka mole oxygen. No ka mea, ʻo ka microorganism i loko o ka membrane e Anabolism i ka waiwai BOD a hoʻopau i ka oxygen, e hoʻemi ʻia ka mole oxygen e komo ana i ka electrode oxygen, ʻo ia hoʻi, e hoʻemi ʻia ka diffusion rate, e hoʻemi ʻia ka mana o ka electrode, a hāʻule ia. i ka waiwai paʻa hou i loko o kekahi mau minuke. Ma loko o ka laulā kūpono o ka BOD, aia kahi pilina laina ma waena o ka emiʻana o ka electrode output current a me ka BOD concentration, oiai aia ka pilina quantitative ma waena o ka BOD a me ka BOD waiwai. No laila, ma muli o ka emi ʻana o kēia manawa, hiki ke hoʻoholo ʻia ka BOD o ka wai i hoʻāʻo ʻia.
LH-BODK81 Biological Chemical oxygen koi BOD microbial sensor rapid tester, i hoʻohālikelike ʻia me nā ʻano ana BOD kuʻuna, ʻo kēia ʻano hou o ka mea ʻike maka he nui nā pono. ʻO ka mea mua, pono nā ʻano ana BOD maʻamau i kahi kaʻina mahiʻai lōʻihi, maʻamau e lawe i nā lā 5-7, aʻo nā mea ʻike hou he mau minuke wale nō e hoʻopau i ke ana. ʻO ka lua, ʻo nā ʻano ana maʻamau e koi i ka nui o nā reagents kemika a me nā mea aniani, ʻoiai ʻaʻole pono nā mea ʻike hou i nā reagents a i ʻole nā mea hana, e hōʻemi ana i nā kumukūʻai hoʻokolohua a me ka hoʻopukapuka kanaka. Eia kekahi, hiki i nā ʻano ana BOD maʻamau ke maʻalahi i nā kūlana kaiapuni e like me ka mahana a me ka māmā, ʻoiai hiki i nā mea ʻike hou ke ana i nā ʻano like ʻole a pane koke i nā loli.
No laila, loaʻa i kēia ʻano hou o ka sensor optical nā manaʻo noiʻi ākea. Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke kahua o ka nānā ʻana i ka maikaʻi o ka wai, hiki ke hoʻohana ʻia kēia sensor ma nā ʻano ʻano like ʻole e like me ka meaʻai, ka lāʻau lapaʻau, ka mālama ʻana i ke kaiapuni, a me ka ʻike ʻana i nā mea kūlohelohe i ke aʻo ʻana i ka lab.
