BOD (Biochemical Oxygen Demand), maererano nekududzirwa kwenyika, BOD inoreva biochemical.
Kudiwa kweokisijeni kunoreva iyo yakanyungudutswa okisijeni inopedzwa netupukanana mu biochemical Chemical process yekuora zvimwe zvinhu zvinogonesa oxidizable mumvura pasi pemamiriro akatarwa.
Kukanganisa kweBOD: Tsvina yemumba uye tsvina yemumaindasitiri ine huwandu hukuru hweakasiyana organic komisheni. Kana zvinhu zvipenyu izvi zvikaora mumvura mushure mekusvibisa mvura, zvinodya okisijeni yakawanda yakanyungudika, zvichikanganisa kuenzana kweokisijeni mumvura, kushata kwemvura, uye kukonzera kufa kwehove nezvimwe zvipenyu zvemumvura nekuda kwe hypoxia. . Iyo organic compounds iri mumitumbi yemvura yakaoma uye yakaoma kuona kune chimwe nechimwe chikamu. Vanhu vanowanzo shandisa okisijeni inopedzwa neorganic matter mumvura pasi pemamwe mamiriro kuti vataure zvisina kunanga zviri mukati meiyo organic matter mumvura, uye Biochemical oxygen kudiwa ndechimwe chezviratidzo zvakakosha zvakadaro. Inoratidza zvakare biodegradability ye organic compounds mumvura ine tsvina.
Chii chinonzi BOD5: (BOD5) inoreva huwandu hweokisijeni yakanyungudika inopedzwa kana sampu yakanyudzwa munzvimbo ine rima pa (20 ± 1) ℃ kwemazuva mashanu ± maawa mana.
Microbial electrode inzwa inosanganisa microbial tekinoroji nemagetsi ekuona tekinoroji. Iyo inonyanya kuve neyakanyungudika okisijeni electrode uye isingafambise microbial firimu yakasungirirwa kune yayo inofema membrane pamusoro. Musimboti wekupindura kuzvinhu zveBOD ndewekuti kana ikaiswa musubstrate isina B0D zvinhu painogara tembiricha uye yakanyungudika oksijeni kugadzika, nekuda kwechimwe chiitiko chekufema kwema microorganisms, mamorekuru eokisijeni akanyungudika mu substrate anopararira muokisijeni electrode kuburikidza. iyo microbial membrane pane imwe chiyero, uye iyo microbial electrode inoburitsa yakatsiga-yemamiriro ikozvino; Kana iyo BOD chinhu chakawedzerwa kune yepasi mhinduro, iyo molecule yechinhu inopararira mukati me microbial membrane pamwe chete neokisijeni molecule. Nekuti iyo microorganism iri mu membrane ichaita Anabolism iyo BOD chinhu uye ichidya okisijeni, iyo okisijeni molecule inopinda muokisijeni electrode ichaderedzwa, ndiko kuti, mwero wekupararira uchaderedzwa, kubuda ikozvino kwe electrode kuchaderedzwa, uye inodonha. kune imwe yakatsiga kukosha mukati memaminitsi mashoma. Mukati mehutano hwakakodzera hwehuwandu hweBOD, pane hukama hwemutsara pakati pekuderera kwe electrode kubuda ikozvino uye BOD concentration, nepo kune hukama hwehuwandu pakati peBOD yekuisa uye BOD kukosha. Naizvozvo, zvichibva pakuderera kwezvino, BOD yemvura yakaedzwa sampu inogona kutsanangurwa.
LH-BODK81 Biological Chemical okisijeni inoda BOD microbial sensor yekukurumidza tester, ichienzaniswa neyechinyakare BOD yekuyera nzira, iyi nyowani mhando yeoptical sensor ine zvakawanda zvakanaka. Chekutanga, echinyakare BOD kuyerwa nzira dzinoda kureba kurima, kazhinji kutora 5-7 mazuva, nepo masensor matsva anongotora maminetsi mashoma kupedzisa kuyerwa. Chechipiri, nzira dzekuyera dzechinyakare dzinoda huwandu hukuru hwemakemikari reagents uye magirazi zviridzwa, nepo ma sensors matsva asingade chero reagents kana zviridzwa, kudzikisa mitengo yekuyedza uye mari yevashandi. Pamusoro pezvo, nzira dzechinyakare dzekuyerwa kweBOD dzinotapukirwa nemamiriro ekunze akadai sekushisa uye chiedza, nepo masensa matsva anogona kuyera munzvimbo dzakasiyana siyana uye kupindura nekukurumidza kune shanduko.
Naizvozvo, iyi mhando nyowani yeoptical sensor ine yakafara tarisiro yekushandisa. Pamusoro pekushandiswa mumunda wekutarisa kwemhando yemvura, sensor iyi inogona zvakare kushandiswa munzvimbo dzakasiyana senge chikafu, mushonga, kuchengetedzwa kwezvakatipoteredza, uye organic nyaya yekuona murabhoritari dzidziso.
