Tus Neeg Sawv Cev Nitrifying Bacteria
Kev piav qhia
Daim Ntawv Thov
Haum rau cov chaw kho dej phwj hauv nroog, txhua yam dej khib nyiab hauv kev lag luam, luam ntawv thiab zas xim dej khib nyiab, dej khib nyiab, dej khib nyiab zaub mov thiab lwm yam kev kho dej khib nyiab.
Cov Haujlwm Tseem Ceeb
1. Tus neeg sawv cev tuaj yeem tsim tau sai sai hauv biochemical system thiab loj hlob bio-zaj duab xis hauv padding, nws hloov ammonia nitrogen thiab cnitrite hauv dej khib nyiab mus rau cov nitrogen tsis muaj teeb meem uas tuaj yeem tso tawm ntawm dej, kom degrade ammonia nitrogen thiab tag nrho nitrogen sai sai. Txo cov ntxhiab tsw phem, tiv thaiv kev loj hlob ntawm cov kab mob putrefying, txo methane, ammonia thiab hydrogen sulfide, txo cov pa phem hauv huab cua.
2. Tus neeg sawv cev nrog cov kab mob nitrifying, tuaj yeem ua kom luv luv ntawm cov sludge activated thiab los ntawm-zaj duab xis lub sijhawm, ua kom ceev nrooj pib ntawm cov dej phwj pov tseg, txo cov dej khib nyiab nyob lub sijhawm, txhim kho tag nrho cov hwj chim ua tiav.
3. Muab cov kab mob nitrifying rau hauv cov dej khib nyiab, tuaj yeem txhim kho kev ua haujlwm ntawm ammonia nitrogen hauv dej khib nyiab los ntawm 60% ntawm cov qub, tsis tas hloov cov txheej txheem kho. Nws tuaj yeem txo tus nqi ua haujlwm, yog ib qho tshuaj uas zoo rau ib puag ncig, ua haujlwm tau zoo, thiab tiv thaiv kab mob me me.
Txoj Kev Thov
Raws li cov ntsuas dej zoo, lub cev biochemical ntawm cov dej khib nyiab kev lag luam:
1. Thawj koob tshuaj yog li ntawm 100-200 grams/cubic (accroding rau biochemical pas dej ntim xam).
2. Qhov ntau npaum li cas ntawm cov dej pub uas tshwm sim los ntawm kev hloov pauv loj dhau los cuam tshuam rau qhov kev txhim kho biochemical system yog 30-50 grams/cubic (raws li kev xam biochemical pas dej ntim).
3. Cov dej khib nyiab hauv nroog yog 50-80 grams/cubic (raws li kev xam qhov ntim ntawm pas dej biochemical)
Cov Lus Qhia Tshwj Xeeb
Cov kev ntsuam xyuas qhia tau hais tias cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg hauv qab no ntawm kev loj hlob ntawm cov kab mob yog qhov zoo tshaj plaws:
1. pH: Qhov nruab nrab ntawm 5.5 txog 9.5, nws yuav loj hlob sai tshaj plaws ntawm 6.6 -7.4, thiab qhov zoo tshaj plaws PH tus nqi yog 7.2.
2. Kub: Siv tau ntawm 8 ℃ - 60 ℃. Cov kab mob yuav tuag yog tias qhov kub siab dua 60 ℃. Yog tias nws qis dua 8 ℃, cov kab mob yuav tsis tuag, tab sis kev loj hlob ntawm cov kab mob cell yuav raug txwv ntau heev. Qhov kub tsim nyog tshaj plaws yog ntawm 26-32 ℃.
3. Cov Pa oxygen yaj: Lub tank aeration hauv cov dej phwj tuaj, cov pa oxygen yaj yog tsawg kawg yog 2 mg / liter. Qhov metabolic thiab regrade tus nqi ntawm cov kab mob tuaj yeem ua kom nrawm dua 5-7 zaug nrog cov pa oxygen tag nrho.
4. Cov Khoom Me Me: Cov kab mob uas yog cov tswv yuav xav tau ntau yam khoom hauv nws txoj kev loj hlob, xws li potassium, hlau, calcium, sulfur, magnesium, thiab lwm yam, feem ntau nws muaj cov khoom txaus hauv av thiab dej.
5. Salinity: Nws siv tau rau hauv dej ntsev siab, 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 muaj cov tshuaj tua kab mob, yuav tsum tau sim seb puas muaj cov kab mob.
