Kev kom
Luv sludge hnub nyoog:
Lub voj voog ib tiam ntawm nitrify cov kab mob yog qhov ntev. Yog hais tias sludge cia sij hawm (SRT) yog luv heev, Nitrify cov kab mob tsis tuaj yeem ua ke nyob rau hauv lub system, ua rau muaj zog nitrification.
Tsis zoo sludge xa rov qab los yog kev tawm tsam ntau dhau tuaj yeem txo qis qis qis qis thiab cuam tshuam nitricificate efficiency.
Kev thau ntau dhau:
Thaum cov organic thauj khoom lossis ammonia nitrogen load yog ntau dhau lawm, Nitrify cov kab mob yog qhov tsis zoo hauv kev sib tw nrog cov kab mob Heterotrophic hauv kev sib tw nrog Nitricification.
Cov Sludge tsis txaus nyob thaum pib pib ntawm lub system, lossis lub sijhawm ua haujlwm luv luv, tseem tuaj yeem ua rau muaj kev thauj ntau dhau.
Qhov chaw tsis tsim nyog sab nraud:
Cov pa oxolven tsis txaus ntseeg (ua): Nitrification yuav tsum tau muaj cov pa roj oxygen txaus, thiab thaum twg yog qis} mg / u, nitrification yuav raug txwv.
Tus kab mob PH tsis zoo: Nitrifify cov kab mob yog nkag siab p tus nqi, nrog ib qho kev pom zoo ntawm {0}}. Tshaj dhau qhov no yuav cuam tshuam lawv cov kev ua ub no roj ntsha.
Cov kab mob kub tsis tsim nyog: Nitrminify cov kab mob tuaj yeem nqa tawm ntawm lub cev cov kev ua si ntawm lub cev hauv qhov ntau ntawm 5-35 degree. Thaum qhov kub nyob hauv qab 5 degree lossis siab dua 40 degree, lawv cov haujlwm yuav raug txwv.
Cov khoom siv tsis zoo los yog ua haujlwm tsis raug:
Lub malfunction ntawm cov khoom siv ntawm kev tawm ua rau tsis muaj txiaj ntsig.
Kev txawv txav Reflux system, cuam tshuam rau sludge reflux thiab sib xyaw ua ke.
Lub tswj hwm kev ua haujlwm tsis zoo, ua rau cov txheej txheem tsis zoo los hloov pauv ntawm qhov qub.
Txoj kev kub ntxhov
Ncua lossis txo qhov tso nyiaj: txo cov zog hluav taws xob thiab muab cov hauv kev rau cov kab mob nitrify kom rov zoo.
Ua kom Aeration Aeration: Ua kom yaj cov pa oxygen los txhawb cov kev ua ub no ntawm nitrify cov kab mob.
Kho Refux piv: nce sab hauv refux piv kom tsim nyog txhim kho kev ua tau zoo nitrification efficiency.
Tswj tus nqi pH tsim nyog: kho tus nqi pH uas haum rau kev loj hlob ntawm nitrifying bacic thiab alkaline tshuaj.
Nres sludge tso tseg: kom tsis txhob poob ntxiv ntawm nitrify bacteria.
Lus teb
Kho sludge hnub nyoog:
Txuas ntxiv lub sludge cia sij hawm, zam kev tawm mus, thiab ua kom muaj kev sib sau ua ke ntawm nitrifying cov kab mob hauv cov kab ke.
Txhim kho cov sludge rov qab system los xyuas kom meej sludge rov qab.
Txo cov thauj khoom:
Txo cov hluav taws xob ruaj khov thiab txo qis ntawm cov concentration ntawm cov organic teeb meem thiab ammonia nitrogen.
Ua kom lub sijhawm nce ntxiv nyob thiab txhim kho kev ua haujlwm tau zoo.
Ua kom qis dua tuaj yeem txuas ntxiv thaum pib pib ua kom sai sai.
Txhim kho qhov chaw sab nraud:
Nce cov pa oxygen kom ntseeg tau tias yog 2. 0-3 mg / l.
Kho tus nqi pH rau qhov kev ua tau zoo tshaj plaws rau nitrify bacteria (8-9).
Tswj cov dej kub nyob rau hauv cov chaw tsim nyog ({5-35 degree) kom zam dhau qhov kev cuam tshuam ntawm huab cua sov ntawm nitrify.
Cov cuab yeej siv dag zog thiab kev tswj hwm:
Txheeb xyuas cov khoom tseem ceeb xws li Aerer cov khoom siv thiab cov tshuab hluav taws xob kom ntseeg tau tias lawv cov haujlwm ib txwm ua.
Ib qho ntxiv dag zog tswj kev tu cev kom ntseeg tau cov txheej txheem ruaj khov.
Txhim kho qib ntawm cov neeg ua haujlwm ntawm cov neeg ua haujlwm, ntxiv dag zog rau kev kawm thiab kev tswj hwm.
Ntxiv Nitrify Cov Kab Mob Nruab Nrab Nruab Nrab:
Tom qab paub meej tias qhov ruaj ntseg ntawm lub system, nitrify cov kab ke kab lis kev cai hauv nruab nrab tuaj yeem ntxiv ua kom nrawm rov qab ntawm cov nitrification system.
Xaiv cov kab lis kev cai uas tsim nyog rau nitrify thiab ntxiv nws raws li qhov xwm txheej tiag tiag ntawm lub system.
Ntxiv dag zog rau cov dej soj ntsuam zoo thiab ua kom ntxov:
Nquag saib lub effluent zoo, kuaj pom kom sai thiab lis cov xwm txheej txawv txav.
Tsim kom muaj kev ceeb toom me ntsis los saib xyuas thiab ceeb toom cov cim taw qhia tseem ceeb hauv lub sijhawm tiag tiag.
