Lub luag haujlwm ntawm cov pa oxygen hauv cov dej phwj tuaj kho yog dab tsi?
Dab tsi yog yaj oxygen? Kev sib raug zoo ntawm cov pa oxygen thiab cov kab mob microorganisms yog dab tsi?
Oxygen yaj hauv dej yog hu ua yaj oxygen. Cov kab mob thiab cov kab mob aerobic hauv lub cev dej cia siab rau cov pa oxygen yaj rau lawv txoj sia. Cov kab mob sib txawv muaj cov kev xav tau sib txawv rau cov pa oxygen yaj. Aerobic microorganisms yuav tsum tau muab cov pa oxygen txaus. Feem ntau hais lus, cov pa oxygen yaj yuav tsum khaws cia ntawm 3mg / L, thiab qhov tsawg kawg nkaus yuav tsum tsis txhob qis dua 2mg / L; Cov kab mob facultative xav tau cov pa oxygen hauv qhov ntau ntawm 0 2-2 0mg/L thaum cov kab mob anaerobic yuav tsum muaj cov pa oxygen yaj hauv qab no 0.2mg/L .
Cov pa oxygen yaj (DO) txhais li cas?
Dissolved oxygen (DO) sawv cev rau tus nqi ntawm cov pa oxygen hauv dej, qhia hauv mg / L. Cov kev kho biochemical sib txawv muaj cov kev xav tau sib txawv rau cov pa oxygen yaj. Hauv cov txheej txheem biochemical facultative, cov pa oxygen yaj hauv dej feem ntau yog nruab nrab ntawm {{{0}}}2-2.0mg / L, thaum nyob rau hauv SBR aerobic biochemical txheej txheem, cov pa yaj. hauv dej feem ntau nyob nruab nrab ntawm 2.0-8 0mg/L. Yog li ntawd, lub aeration ntim thiab aeration lub sij hawm yuav tsum me me thiab lub sij hawm aeration yuav tsum luv luv thaum lub facultative tank ua hauj lwm; thaum lub sij hawm aeration thiab lub sij hawm aeration yog ntau dua thiab ntev dua thaum lub SBR aerobic tank ua haujlwm, thiab peb siv qhov kev sib cuag Oxidation, yaj cov pa oxygen tswj ntawm 2.0-4.0mg/L.
Dab tsi cuam tshuam txog cov ntsiab lus ntawm cov pa oxygen hauv cov dej khib nyiab?
Qhov concentration ntawm cov pa oxygen yaj hauv dej tuaj yeem qhia tau los ntawm Henry txoj cai: thaum qhov sib npaug sib npaug mus txog: C=KH * P
Ntawm lawv: C yog solubility ntawm oxygen nyob rau hauv dej ntawm lub dissolution equilibrium; P yog lub siab ib nrab ntawm cov pa hauv cov pa roj; KH yog Henry coefficient, uas muaj feem xyuam rau qhov kub thiab txias; nce aeration los ua kom cov pa oxygen nyob ze rau qhov sib npaug, thiab tib lub sijhawm, cov activated sludge yuav haus dej ntawm oxygen. Yog li, qhov tseeb ntawm cov pa oxygen yaj hauv cov dej khib nyiab muaj feem xyuam rau cov dej kub, qhov dej tob tob ( cuam tshuam rau lub siab), tus nqi aeration, sludge concentration, salinity thiab lwm yam.
Leej twg muab cov pa oxygen xav tau los ntawm cov kab mob hauv cov txheej txheem biochemical?
Cov pa oxygen xav tau los ntawm cov kab mob hauv cov txheej txheem biochemical feem ntau yog muab los ntawm cov cuab yeej aeration.
Yuav ua li cas ntsuas tus nqi oxygen yaj?
Siv lub ntsuas pa oxygen rau lub sijhawm saib xyuas online.
Dab tsi ntawm cov pa oxygen yaj meter tuaj yeem raug thiab lub sijhawm tawm tswv yim txog cov ntsiab lus oxygen yaj hauv cov dej phwj tuaj?
Fluorescent yaj oxygen yog qhov tsim nyog rau kev kho dej phwj tuaj, vim tias nws yuav tsis cuam tshuam los ntawm lwm cov ions hauv cov dej phwj tuaj, tsis siv cov pa oxygen, tsis txwv los ntawm tus nqi ntws, tsis tas yuav tsum tau calibration nquag, tsis tu ncua, kev pab lub neej ntev, thiab tuaj yeem ua tau. saib xyuas hauv online tau ntev.
Dab tsi yog qhov zoo ntawm huab-based IoT fluorescence yaj oxygen sensor?
1) Master thev naus laus zis thev naus laus zis, tshwj xeeb thiab ua cov khoom fluorescent, cov lus teb rhiab thiab ntsuas qhov tseeb dua.
2) Nws muaj nws tus kheej machining chaw thiab CNC tshuab cuab yeej.
3) Muaj ib pab kws tshaj lij los ntawm lub teb chaws Yelemees.
