Kev piav qhia
Nws yog ib qho hmoov dawb thiab muaj cov kab mob thiab cocci, uas tuaj yeem tsim cov spores (endospores).
Muaj ntau tshaj 20 billion/gram cov kab mob uas muaj sia nyob
Daim Ntawv Thov
Cov Haujlwm Tseem Ceeb
1. Tus neeg sawv cev kab mob muaj kev ua haujlwm zoo ntawm cov organic hauv dej. Vim yog cov kab mob spore muaj zog heev tiv taus cov yam ntxwv phem ntawm lub ntiaj teb sab nraud. Nws tuaj yeem ua rau lub kaw lus kho dej phwj tuaj yeem tiv taus qhov cuam tshuam thauj khoom, thiab muaj peev xwm tuav tau zoo, lub kaw lus tuaj yeem khiav kom zoo thaum cov dej phwj tuaj yeem hloov pauv ntau yam, xyuas kom meej tias cov dej phwj tuaj yeem ruaj khov.
2. Cov kab mob aerobic tuaj yeem tshem tawm BOD, COD thiab TTS tau zoo. Txhim kho qhov peev xwm ntawm cov khoom khov hauv cov dej phwj tuaj, ua rau muaj ntau thiab ntau yam ntawm cov protozoa.
3. Pib thiab Rov Qab System Sai sai, txhim kho kev ua haujlwm thiab kev cuam tshuam tsis kam ntawm lub kaw lus, txo cov sludge seem tsim tau zoo, txo kev siv cov tshuaj xws li flocculant, txuag hluav taws xob.
Txoj Kev Thov
1. Raws li cov ntsuas dej zoo rau hauv lub cev biochemical ntawm cov dej khib nyiab lag luam: thawj koob tshuaj yog li 80-150 grams / cubic (raws li kev xam ntim ntawm lub pas dej biochemical).
2. Yog tias nws muaj kev cuam tshuam loj heev rau lub cev biochemical uas tshwm sim los ntawm kev hloov pauv ntawm cov dej pub, ntxiv ntxiv 30-50 grams / cubic ib hnub (raws li kev xam qhov ntim ntawm lub pas dej biochemical).
3. Cov dej khib nyiab hauv nroog yog 50-80 grams/cubic (raws li kev xam qhov ntim ntawm lub pas dej biochemical).
Cov Lus Qhia Tshwj Xeeb
Qhov kev sim qhia tau hais tias cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg hauv qab no rau kev loj hlob ntawm cov kab mob yog qhov zoo tshaj plaws:
1. pH: Nyob rau hauv qhov ntau ntawm 5.5 thiab 9.5, qhov kev loj hlob sai tshaj plaws yog ntawm 6.6-7.8, kev xyaum ua pov thawj qhov ua tau zoo tshaj plaws hauv PH 7.5.
2. Kub: nws yuav pib ua haujlwm ntawm 8 ℃ -60 ℃. Cov kab mob yuav tuag yog tias qhov kub siab dua 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 kub tsim nyog tshaj plaws yog ntawm 26-32 ℃.
3. Cov Pa oxygen yaj: Cov pa oxygen yaj tsawg kawg yog 2 mg / l hauv lub tank aeration ntawm kev kho dej khib nyiab; qhov kev ua haujlwm thiab kev puas tsuaj ntawm cov kab mob siab resilience rau cov khoom lag luam yuav nrawm dua 5 ~ 7 zaug nrog cov pa oxygen txaus.
4. Cov Khoom Siv Tau: Cov kab mob uas yog cov kab mob tshwj xeeb yuav xav tau ntau yam khoom siv hauv nws txoj kev loj hlob, xws li potassium, hlau, sulfur, magnesium, thiab lwm yam. Feem ntau, nws muaj cov khoom siv txaus hauv av thiab dej.
5. Salinity: Nws muaj feem xyuam rau dej ntsev thiab dej tshiab, qhov siab tshaj plaws ntawm salinity yog 6%.
6. Kev Tiv Thaiv Tshuaj Lom: Nws tuaj yeem tiv taus cov tshuaj lom neeg, suav nrog chloride, cyanide thiab cov hlau hnyav, thiab lwm yam zoo dua.

Thaum thaj chaw muaj kuab paug uas muaj cov tshuaj fungicides, yuav tsum tshawb nrhiav cov txiaj ntsig ntawm lawv rau cov kab mob me me ua ntej.
Tam sim no peb muaj cov neeg ua haujlwm tshwj xeeb thiab ua haujlwm tau zoo los muab kev pabcuam zoo rau peb cov neeg siv khoom. Peb feem ntau ua raws li lub hauv paus ntsiab lus ntawm kev tsom mus rau cov neeg siv khoom, tsom mus rau cov ntsiab lus kom xa khoom sai Gram Positive quotecov tshuaj ntxiv rau cov kab mob aerobicYog koj xav paub ntxiv txog peb cov khoom, thov koj xa koj cov lus nug rau peb dawb. Peb vam tias yuav nrhiav tau kev sib raug zoo nrog koj thiab ua lag luam zoo.
Kev xa khoom sai, cov tshuaj aerobic bacteria ntxiv, Peb qhov zoo yog peb txoj kev tsim kho tshiab, kev ywj pheej thiab kev ntseeg siab uas tau tsim tsa hauv 20 xyoo dhau los. Peb tsom mus rau kev muab kev pabcuam rau peb cov neeg siv khoom ua lub hauv paus tseem ceeb hauv kev txhawb nqa peb txoj kev sib raug zoo mus sij hawm ntev. Kev muaj cov khoom lag luam zoo tas mus li ua ke nrog peb cov kev pabcuam ua ntej thiab tom qab muag zoo heev ua kom muaj kev sib tw zoo hauv kev lag luam thoob ntiaj teb.
