bacteriological cov khoom rau dej phwj kho ntawm nqaij npuas thiab nqaij qaib ua liaj ua teb
Peb txhawb peb cov neeg yuav khoom nrog cov khoom lag luam zoo tshaj plaws thiab cov tuam txhab qib siab.Ua cov chaw tsim khoom tshwj xeeb hauv cov haujlwm no, peb tau txais kev nplua nuj ua haujlwm ua haujlwm hauv kev tsim khoom thiab tswj xyuasbacteriological khoommus rau dej phwj kho mob ntawm nqaij npuas thiab nqaij qaib ua liaj ua teb, Peb tab tom sim kom tau rau hauv qhov tob kev koom tes nrog cov neeg siv khoom ncaj ncees, ua tiav cov txiaj ntsig tshiab ntawm lub yeeb koob nrog cov neeg siv khoom thiab cov neeg koom tes zoo.
Peb txhawb peb cov neeg yuav khoom nrog cov khoom lag luam zoo tshaj plaws thiab cov tuam txhab qib siab.Ua cov chaw tsim khoom tshwj xeeb hauv cov haujlwm no, peb tau txais kev nplua nuj ua haujlwm ua haujlwm hauv kev tsim khoom thiab tswj xyuasbacteriological khoom, Noj cov ntsiab lus tseem ceeb ntawm "ua lub luag haujlwm".Peb yuav rov hais dua rau hauv zej zog rau cov kev daws teeb meem zoo thiab kev pabcuam zoo.Peb tab tom yuav pib koom nrog hauv kev sib tw thoob ntiaj teb los ua thawj cov chaw tsim khoom ntawm cov khoom no hauv ntiaj teb.
Kev piav qhia
Nws yog cov hmoov dawb thiab muaj cov kab mob thiab cocci, uas tuaj yeem tsim spores (endospores).
Muaj ntau tshaj 20 billion/gram cov ntsiab lus ntawm cov kab mob nyob
Daim ntawv thov teb
Lub luag haujlwm tseem ceeb
1. Tus neeg sawv cev ntawm cov kab mob muaj txiaj ntsig zoo degradation ntawm cov organic teeb meem hauv dej.Vim hais tias ntawm cov kab mob spores muaj zog heev tiv thaiv cov teeb meem ntawm lub ntiaj teb sab nraud.Nws tuaj yeem ua rau cov dej phwj tuaj yeem muaj peev xwm tiv taus qhov cuam tshuam, thiab muaj peev xwm tuav tau zoo, lub kaw lus tuaj yeem ua haujlwm tau zoo thaum cov dej phwj tuaj hloov pauv ntau, ua kom cov dej ntws tawm ruaj khov.
2. Cov kab mob aerobic tuaj yeem tshem tawm BOD, COD thiab TTS zoo.Txhim kho qhov muaj peev xwm daws teeb meem hauv cov phev sedimentation loj, nce tus naj npawb thiab ntau haiv neeg ntawm protozoa.
3. Pib thiab rov ua haujlwm ceev ceev, txhim kho kev ua tau zoo thiab muaj peev xwm tiv taus lub zog ntawm lub cev, txo qhov seem ntawm cov sludge generated zoo, txo cov kev siv tshuaj xws li flocculant, txuag hluav taws xob.
Txoj kev thov
1.Raws li dej zoo Performance index rau hauv biochemical system ntawm cov dej khib nyiab: thawj koob yog li 80-150 grams / cubic (raws li qhov ntim xam ntawm lub pas dej biochemical).
2.Yog tias nws muaj kev cuam tshuam loj heev rau cov kab mob biochemical uas tshwm sim los ntawm cov dej hloov pauv, ntxiv 30-50 grams / cubic ib hnub (raws li kev suav ntim ntawm lub pas dej biochemical).
3.Qhov ntau npaum ntawm cov dej khib nyiab hauv nroog yog 50-80 grams / cubic (raws li kev suav ntim ntawm lub pas dej biochemical).
Specification
Qhov kev sim qhia tau hais tias cov hauv qab no lub cev thiab tshuaj tsis haum rau cov kab mob loj hlob zoo tshaj plaws:
1. pH: Nyob rau hauv thaj tsam ntawm 5.5 thiab 9.5, kev loj hlob sai tshaj plaws yog nyob nruab nrab ntawm 6.6-7.8, kev xyaum ua pov thawj qhov ua tau zoo tshaj plaws hauv PH 7.5.
2. Kub: nws yuav siv sij hawm ntawm 8 ℃-60 ℃.Cov kab mob yuav tuag yog tias qhov kub siab tshaj 60 ℃.Yog tias nws qis dua 8 ℃, nws yuav tsis tuag, tab sis kev loj hlob ntawm cov kab mob yuav raug txwv ntau heev.Qhov zoo tshaj plaws kub yog nyob nruab nrab ntawm 26-32 ℃.
3. Dissolved Oxygen: Lub yaj cov pa tsawg kawg yog 2 mg / l nyob rau hauv lub aeration tank ntawm cov dej khib nyiab kho;cov metabolism thiab degradation ceev ntawm cov kab mob siab resilience rau lub hom phiaj cov khoom yuav ceev 5 ~ 7 zaug nrog txaus oxygen.
4. Cov ntsiab lus kab: Cov kab mob uas muaj peev xwm yuav xav tau ntau yam hauv nws txoj kev loj hlob, xws li potassium, hlau, sulfur, magnesium, thiab lwm yam. Feem ntau, nws muaj cov ntsiab lus txaus hauv av thiab dej.
5. Salinity: Nws muaj feem xyuam rau hauv cov dej ntsev thiab dej tshiab, qhov siab tshaj plaws ntawm salinity yog 6%.
6. Kev Ua Phem Txhaum Cai: Nws tuaj yeem tiv taus cov tshuaj lom tshuaj lom neeg ntau dua, suav nrog chloride, cyanide thiab cov hlau hnyav, thiab lwm yam.
Daim ntawv ceeb toom
Thaum cov kab mob kis tau cov kab mob fungicides, yuav tsum tshawb xyuas cov txiaj ntsig ntawm lawv rau cov kab mob ua ntej.
Peb txhawb peb cov neeg yuav khoom nrog cov khoom lag luam zoo tshaj plaws thiab cov tuam txhab qib siab.Los ua cov chaw tsim khoom tshwj xeeb hauv cov haujlwm no, peb tau txais kev paub ua haujlwm zoo hauv kev tsim thiab tswj cov khoom siv bacteriological rau cov dej phwj tuaj kho cov nqaij npuas thiab nqaij qaib ua liaj ua teb, Peb tab tom sim kom tau txais kev koom tes hauv qhov tob nrog cov neeg yuav khoom siab dawb, tau txais txiaj ntsig tshiab ntawm koob meej nrog cov neeg muas zaub thiab cov tswv yim koom tes.
Cov khoom lag luam bacteriological, Noj cov ntsiab lus tseem ceeb ntawm "ua lub luag haujlwm".Peb yuav rov hais dua rau hauv zej zog rau cov kev daws teeb meem zoo thiab kev pabcuam zoo.Peb tab tom yuav pib koom nrog hauv kev sib tw thoob ntiaj teb los ua thawj cov chaw tsim khoom ntawm cov khoom no hauv ntiaj teb.
