Mbbr Lim Media

MBBR lim xov xwm yog ib yam khoom tshiab tsim los muab qhov chaw loj hlob zoo rau cov kab mob, nrog rau cov qauv hollow ua cov khoom ntim. Los ntawm kev siv cov qauv kev tshawb fawb los hloov cov ntaub ntawv polymer los ntawm cov txheej txheem tshwj xeeb, nws muaj ntau qhov zoo, suav nrog thaj chaw loj tshwj xeeb, zoo hydrophilicity, muaj zog tiv thaiv, tsim cov yeeb yaj kiab yooj yim, nrawm nrawm thiab loj hlob ntawm cov kab mob, thiab kev kho dej zoo heev. Nws tau siv dav hauv ntau qhov chaw xws li cov dej phwj hauv nroog, cov dej khib nyiab, cov dej phwj hauv nroog, thiab kev kho tsiaj cov tsiaj txhu.

Nyob rau hauv cov txheej txheem aerobic fluidized txaj, MBBR lim xov xwm ua raws li cov cab kuj aerobic. Kev ntim khoom, nrog nws cov qauv hollow, ua haujlwm los ntawm qhov seem raug tshem tawm hauv dej. Cov kab mob anaerobic loj hlob hauv cov khoom ntim, yooj yim denitrification kom tshem tawm nitrogen; Cov kab mob aerobic loj hlob rau sab nrauv kom tshem tawm cov organic teeb meem. Ob qho tib si nitrification thiab denitrification txheej txheem tshwm sim thaum lub sij hawm kho.

Filler Ntxiv Theem:

Thaum ntxiv MBBR lim xov xwm, saib seb puas muaj kev txuam nrog. Yog tias tsub zuj zuj tshwm sim, nres ntxiv. Tos kom txog hnub tom qab, mam li soj ntsuam ntxiv ua ntej ntxiv ntxiv.

Thaum lub sij hawm sib ntxiv ntawm muab tub lim, siv intermittent aeration. Aeration tuaj yeem txuas ntxiv thaum hmo ntuj, tab sis qhov ntim yuav tsum tau txo.

Tom qab 24 teev ntawm kev ua haujlwm, txuas ntxiv dej ntxiv rau 2-3 teev, thiab rov pib dua cov txheej txheem aeration. Tom qab 48 teev ntawm kev ua haujlwm, saib xyuas qhov tsim ntawm biofilm ntawm qhov muab tub lim, ua kom cov dej ntws, thiab ncua sij hawm dej ntws. Txheeb xyuas cov qib oxygen yaj hauv lub pas dej ua ke, ua kom nws nyob ib puag ncig 1.5-2.0 mg / L. Tom qab 72 teev ntawm kev ua haujlwm, tshuaj xyuas cov dej ntws thiab maj mam kho nws kom ua tau raws li cov qauv tsim. Kev tshuaj xyuas niaj hnub ntawm cov dej nkag thiab qhov hluav taws xob zoo yuav tsum tau qhia tias cov qauv tsim dej yuav tsum tau ua tiav li ntawm 7 hnub.

Lub sijhawm luv biofilm tsim: Lub sij hawm tsim biofilm yog 3-15 hnub, uas yog 2 hnub sai dua li cov txheej txheem ib txwm muaj thiab tsis tas yuav tsum tau cog cov kab mob ua ntej.

Kev kho deg tshwj xeeb: Qhov loj dua thiab rougher sab hauv txhim kho micro-cell adhesion, tso cai rau kev tsim biofilm sai.

Zoo hydrophilicity: Hydrophilic pawg tau ntxiv los txhim kho biofilm tsim thiab nce biomass.

Tsawg peev thiab cov nqi khiav lag luam: Cov kab ke no tuaj yeem txo qhov ntim thiab hneev taw ntawm cov txheej txheem kev ua haujlwm, txuag cov nqi vaj tsev mus txog 30% lossis ntau dua.

Kev hloov kho hluav taws xob saum npoo ntawm MBBR biofillers: Kev hloov kho saum npoo yog qhov zoo tagnrho rau kev loj hlob ntawm cov kab mob feem ntau, ua rau cov kab mob ntev ntev nrog cov sludge tsawg tsawg, uas txo cov nqi kho sludge zoo heev.

Kev tshem tawm ntawm BOD5, COD, TSS, thiab lwm yam.: Tshem tawm cov kab mob xws li BOD5, COD, thiab TSS.

Durability hauv dej khib nyiab: Siv cov ntaub ntawv copolymer, cov fillers no yuav tsis degrade los yog muaj tshuaj lom los ntawm cov kab mob txawm tias tom qab ntev raug rau cov dej khib nyiab, ua rau lawv superior rau cov ntaub ntawv xws li polyvinyl chloride.

Cov qauv tshwj xeeb, ib qho - sij hawm molding: Cov fillers yog molded nyob rau hauv ib thooj, ua kom muaj kev ncaj ncees.

Siab tshwj xeeb thaj chaw: Ordinary microorganisms muaj thaj chaw tshwj xeeb ntawm 90-180 m²/m³. Hollow fillers tuaj yeem muaj thaj tsam tshwj xeeb txog li 600 m² / m³, thiab ob txheej txheej tuaj yeem ncav cuag ntau dua 860 m² / m³. Vim lawv qhov chaw tshwj xeeb siab, biomass ib chav tsev ntim yog siab, ua tiav lub sijhawm luv hydraulic.

Kev ua haujlwm siab microbial: Cov zaj duab xis microbial loj hlob nyob rau saum npoo ntawm cov muab tub lim yog txhawb nqa los ntawm kev sib tsoo thiab kev sib tsoo. Aeration flushing khaws cov kab mob hauv lub logarithmic loj hlob theem, ua rau muaj kev ua haujlwm siab thiab kev kho mob.

Floating hom, hloov tau yooj yim, thiab lub neej ua haujlwm ntev: Lub hollow fillers yog tsim los rau ntab, ua rau lawv yooj yim los hloov thiab ua kom lub neej ua haujlwm ntev.

Muaj zog muaj peev xwm tshem tawm nitrogen thiab decompose organic teeb meem: Ua tiav lub hom phiaj ntawm kev tshem tawm ammonia nitrogen thiab ua kom cov organic teeb meem zoo.

Txhim kho thiab txhim kho lub peev xwm ntawm engineering dej phwj kho tej yaam num

Kev kho cov dej phwj tuaj tshiab siv MBBR, lub txaj fluidized, thiab cov txheej txheem biofilter
