Tus Neeg Sawv Cev Rau Cov Kab Mob Denitrifying
Kev piav qhia
Daim Ntawv Thov
Haum rau lub kaw lus hypoxia ntawm cov chaw kho dej khib nyiab hauv nroog, txhua yam kev lag luam tshuaj lom neeg pov tseg dej, luam ntawv thiab dyeing pov tseg dej, khib nyiab leachate, zaub mov pov tseg dej thiab lwm yam kev lag luam pov tseg dej kho.
Cov Haujlwm Tseem Ceeb
1. Nws muaj kev ua haujlwm zoo nrog Nitrate thiab Nitrite, tuaj yeem txhim kho qhov ua tau zoo ntawm denitrification thiab tswj hwm qhov ruaj khov mus sij hawm ntev ntawm lub kaw lus ntawm nitrification.
2. Tus neeg sawv cev denitrifying bacterium tuaj yeem rov qab tau sai sai los ntawm lub xeev ntawm kev ntxhov siab uas ua rau los ntawm kev cuam tshuam thiab denitrification ntawm cov yam ntxwv tam sim ntawd.
3. Ua kom muaj kev cuam tshuam rau Nitrogen nitrification rov qab mus rau qhov tsawg kawg nkaus hauv qhov system ruaj ntseg tsis zoo.
Txoj Kev Thov
1. Raws li cov ntsuas dej zoo rau hauv lub cev biochemical ntawm cov dej khib nyiab kev 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, qhov kev kho kom zoo dua yog 30-50 grams / cubic (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, kev loj hlob sai tshaj plaws yog ntawm 6.6-7.4.
2. Kub: Nws yuav pib ua haujlwm ntawm 10 ℃ -60 ℃. Cov kab mob yuav tuag yog tias qhov kub siab dua 60 ℃. Yog tias nws qis dua 10 ℃, 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: Hauv cov pas dej ua kom dej phwj tuaj, cov pa oxygen yaj hauv qab 0.5mg / liter.
4. Micro-Element: Cov kab mob uas yog cov kab mob tshwj xeeb yuav xav tau ntau yam khoom noj rau nws txoj kev loj hlob, xws li potassium, hlau, sulfur, magnesium, thiab lwm yam. Feem ntau, nws muaj cov khoom noj 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. Thaum siv cov txheej txheem thov ua tib zoo saib xyuas SRT lub sijhawm khaws cia khoom, carbonate basicity thiab lwm yam kev ua haujlwm, rau qhov zoo tshaj plaws ntawm cov khoom no.
7.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.
