MBBR Integrated Sewage Treatment Equipment Principles thiab Yam ntxwv
Jun 17, 2022
Lub hauv paus ntsiab lus ua haujlwm ntawm MBBR cov khoom siv dej phwj sib xyaw ua ke yog qhov zoo ib yam li cov khoom siv dej phwj hauv tsev. Tom qab thawj theem kev kho mob, xws li kev cuam tshuam ntawm ntau yam khib nyiab hauv cov dej phwj tuaj hauv cov dej phwj tuaj kom tsis txhob thaiv cov twj tso kua mis los yog cov khoom siv ua haujlwm, nkag mus rau cov txheej txheem thib ob. Cov txheej txheem kho biochemical feem ntau yog nyob ntawm AO cov txheej txheem lom neeg. Nyob rau hauv lub lim tank, cov organic concentration ntawm cov dej phwj yog kuj siab. Lub sijhawm no, nyob rau hauv ib puag ncig hypoxic, cov organic nitrogen hauv cov kav dej yuav raug hloov mus rau NH3-N. Nyob rau tib lub sijhawm, * lim tsis tsuas yog muaj kev tshem tawm cov organic siab, tab sis kuj txo cov kev siv ntawm cov khoom siv tom ntej. Hauv cov lim dej O-class, nws tsuas yog siv cov pa oxygen zoo thiab cov kab mob ntawm tus kheej. Tom qab ntawd Cov nyhuv nitrification tshem tawm cov pa phem nitrogen hauv cov dej phwj tuaj, thiab cov dej phwj tuaj ua tiav.
Vim tias nws muaj peev xwm tshem tawm phosphorus thiab tshem tawm phosphorus, tsuav yog kho cov khoom siv, cov khoom siv tuaj yeem kho tau zoo. Feem ntau ntawm cov kav dej phwj tuaj yeem kho tau zoo kawg nkaus. Daim ntawv thov ntau yog dav heev, thiab cov dej zoo ntawm cov dej phwj tuaj kho yog ruaj khov. Cov khoom siv kho dej phwj tuaj yeem muab tso rau hauv av raws li qhov xav tau lossis muab faus rau hauv av. Cov khoom siv tuaj yeem siv rau saum cov khoom siv. Lub cheeb tsam ntawm lub Hoobkas yog me me, cov qauv hauv av yog me me, tag nrho cov txheej txheem ntawm cov cuab yeej tswj tau tag nrho, thiab kev tswj xyuas kev ua haujlwm tsuas yog txo qis.
Cov yam ntxwv ntawm cov khoom siv dej phwj sib xyaw ua ke:
1. Kev kho dej phwj tuaj yeem siv tshuab, kev lag luam thiab tsim qauv tsim qauv tsim nyog, siv zog txuag hluav taws xob, txo kev siv, txo cov peev txheej engineering, tsis tshua muaj nqi, kev tswj kev ua haujlwm yooj yim, thiab cov txheej txheem kev kho dej phwj tuaj.
2. Cov txheej txheem ruaj khov, kev ua haujlwm siab, muaj zog tiv thaiv kev cuam tshuam lub peev xwm, kev ua haujlwm yooj yim, tsim nyog cov khoom tsim, thiab cov qauv compact.
3. Kev xaiv cov khoom siv kho dej phwj yuav tsum tau ua kom zoo, ruaj khov thiab txhim khu kev lag luam, txuag nqi, kev saib xyuas yooj yim, thiab kev pab lub neej ntev.
Cov hauv paus ntsiab lus ntawm kev kho dej phwj tuaj
1. Siv cov cuab yeej tsim khoom uas tsis muaj tshuaj lom los hloov cov khoom siv rov qab, thiab tshem tawm lossis txo cov dej phwj tuaj yeem ua rau muaj kev phom sij thaum lub sijhawm tsim khoom.
2. Nyob rau hauv cov txheej txheem ntawm kev siv cov tshuaj lom thiab tsim cov tshuaj lom thiab cov khoom, nws yuav tsum tau ua nruj me ntsis thiab saib xyuas, tshem tawm thiab txo qhov poob, thiab siv cov khoom siv tes ua thiab cov khoom tsim nyog kom ntau li ntau tau.
3. Dinus dej uas muaj cov tshuaj lom, xws li cov hlau hnyav, cov khoom siv hluav taws xob, cov phenols siab, thiab cyanols ntawm cov dej cyanolic yuav tsum tau hloov nrog lwm cov dej khib nyiab txhawm rau kho thiab rov ua cov khoom muaj txiaj ntsig.
4. Cov dej khib nyiab nrog cov dej ntws loj thiab lub teeb muaj kuab paug yuav tsum tau rov ua kom zoo thiab rov siv dua. Nws yuav tsum tsis txhob muab tso rau hauv lub kav dej kom tsis txhob ua kom cov kav dej hauv nroog thiab cov dej phwj tuaj kho hauv nroog.
5. Cov dej khib nyiab zoo ib yam li cov dej phwj hauv nroog, xws li cov dej khib nyiab ua zaub mov, dej qab zib-ua cov dej khib nyiab, thiab cov dej khib nyiab papermaking tuaj yeem tso rau hauv cov dej phwj tuaj kho.
6. Qee cov dej khib nyiab uas tuaj yeem ua rau biodegradable, xws li phenols thiab cyanomy khib nyiab, tau ua tiav, thiab tom qab ntawd tawm mus rau hauv lub nroog cov kav dej los ntawm cov qauv emission, thiab tom qab ntawd kho biochemical ntxiv.
7. Cov dej khib nyiab uas muaj qhov nyuaj biodegradation yuav tsum tau ua tiav nyias thiab tsis tuaj yeem tso rau hauv cov kav dej hauv nroog. Txoj kev loj hlob ntawm kev kho dej phwj tuaj yog los siv cov dej khib nyiab thiab cov pa phem ua kom muaj txiaj ntsig zoo los ntawm kev rov ua dua tshiab los yog kaw kev ncig.
