Tom qab kev ua haujlwm
- Qhov Teeb Meem:Cov kev kho mob ntawm cov dej phwj tuaj tau mus txog qhov kawg ntawm nws lub neej ua haujlwm, thiab muaj teeb meem kev ua kom zoo li qub, thiab txo cov peev txheej ntau lawm.
- Lub hom phiaj:Tsim kom muaj lub zog ua haujlwm nrog lub peev xwm ntawm 50,000 m³ / hnub, suav nrog cov cuab yeej cuam tshuam.
- Nyuaj:1. Ua tiav chav dej lim dej zoo tshaj 2. Tshem tawm nitrogen thiab phosphorus hauv cov txheej txheem biochemical
Nrog rau cov cai ntawm kev loj hlob hauv nroog, ib puag ncig kev kho thiab dub thiab odorous dej, qhov kev thov rau kev kho dej khib nyiab ib ncig ntawm cov dej phwj tuaj yeem nce ntxiv. Nws cov MBR MBBRH tau ua haujlwm tau ua haujlwm txij li xyoo xyoo 2013, siv submerf rastrefration membrane Cheebtsam nrog 0.1 μm. Lub qhov dej phwj xaim cog muaj lub peev xwm tsim muaj 10,000 lo lo lus teb meters / hnub thiab Adopts AoA + MBR cov txheej txheem. Cov kev kho effluent ntsib cov chav kawm ib tus qauv ntawm cov pa paug paug qauv rau nroog dej phwj (GB 18919-2002). Tam sim no, nws yuav tsum tau hloov kho MBR MRBRANE system kom tau raws li kev sib tw thiab kev xav tau kev pab.
Txheej txheem cej luam ntawm lub lim dej khib nyiab
Txheej Txheem Flow
Cov txheej txheem ntws, raws li muaj nyob hauv daim duab 1, suav nrog kev kho mob me me thiab tiv thaiv cov pob zeb mBr Kev kho mob theem nrab ntiav AAO + MBR cov txheej txheem, suav nrog pre-}} anoxic tank thiab txhim kho tshuaj phosphorus tshem tawm hauv lub aerobic tank raws li qhov xav tau. Qhov effluent yog tsau tshuaj nrog UV ua ntej raug tso tawm. Sludge kev kho mob muaj lub cev thickening thiab tob dewatering los ntawm phaj ncej los ntawm kev ua tiav 50-60 cov ntsiab lus noo noo ua ntej pov tseg ua ntej pov tseg.
Cuam tshuam thiab effluent zoo
Cov nroj tsuag yog tsim kom ua tiav cov chav kawm effluent zoo qauv. Raws li cov inflow, muaj ntau yam kev sib txawv tuaj yeem sib txawv, xav tau tsom rau nitrogen thiab phosphorus tshem tawm hauv cov txheej txheem biochemical.
Cov xwm txheej tam sim no thiab teeb meem hauv MBR MBR MRBRANE system
MBB SYST
MBR WRHBRANE THIAB COV KHOOM SIV LUB ROOJ *: Daim MBR Wa -S thiab UV Cov Khaub Ncaws Pob, muaj ob daim duab tso tawm hauv ib pawg (tag nrho 176 teev ntawm pvdf fiber mem nrog<0.1 μm pores and a total surface area of approximately 281,600 m²). The system operates with 22 independently controlled production units divided into two separate systems for easy maintenance, allowing both online and offline cleaning. The equipment room houses production, vacuum, backwash, and sludge pumps, along with air scrubbers using 4 air suspension centrifugal blowers (3 operating, 1 standby; parameters: Q=208 Nm³/min, P=50 kPa).
Tshuaj Tu Chav Rau Chav Tshuaj *: Nyob rau saum toj ntawm thaj chaw tsim khoom siv rau cov kua qaub, alkali, thiab naclo rau MBR system.
MBR ua haujlwm *: Cov pas dej ua ke yog ua haujlwm hauv 8-min ntau lawm thiab 2-m huab cua scour hom. Txhua lub pas dej hla cov xuab moos teev (kev ntxuav cov tshuaj online) uas muaj kev ntxuav tes ua ntej, ib qho 15-min ntxuav, thiab ib qho 8-min ncua. Kev ntxuav kab mob offline yog ua txhua lub lim tiam ntawm ib lub pas dej daim nyias nyias.
Cov teeb meem thiab cov laj thawj hauv MBR IDBBRANE
Cov teeb meem tseem ceeb suav nrog flux txo / txo qhov muaj peev xwm / fiber ntau dua thiab txhaws / nqus tau. Cov laj thawj suav nrog:
1. Daim nyias nyias ncav cuag lub neej tsim - Kev ua tau zoo tsawg, cuam tshuam rau flux thiab peev xwm
2. Kev ua haujlwm ntau dhau thiab siv {- ua rau muaj kev lom zem funch chanch
3. Irreversible scaling, nce transmembrane siab -}}} cuam tshuam rau flux
4. Nce tu - Kev ua haujlwm zoo, ua rau muaj peev xwm ntau lawm
5. Txij Nkawm Ntxov Ntxhua Khaub Ncaws -} exacerbating membrane defadation
Cov kev daws teeb meem
1. Kev Mus Los Rau
Hloov kho yuav ua kom cov khaub ncaws uas twb muaj lawm thaum kho tus qauv sab hauv thiab hloov cov tshiab flux PVDF ultrafiltration membranes (<0.1 μm).
2. Tsim kev suav
Cell tam sim no Flux *: Txhua daim duab puab muaj 8 lub cassettes nrog rau thaj tsam ntawm 12,800 m² rau ib lub cell, thiab qhov tam sim no flux tam sim no los ntawm 7.8 txog 15.6 L / (M²² H).
Cov haujlwm ua haujlwm *: Lub kaw lus yuav txuas ntxiv nrog 8-min kev ua haujlwm ntawm / 2-nphoo ua haujlwm, nrog ib daim nyias nyias ua haujlwm offline rau kev ntxuav txhua hnub thiab lwm lub sijhawm kev tu online. Yuav kom ua tiav cov hom phiaj muaj peev xwm, tag nrho cov phiaj xwm lub peev xwm yuav tsum yog tsawg kawg 140,800 m², nrog flux li ntawm 13.6-22.7 L / (M²K BACK.
3. Txhim Kho Txoj Kev Npaj
Hloov cov qauv tam sim no nrog siab dua - kev ua tau zoo cov khoom siv, thiab tswj cov khoom siv qub, cov raj roj piping, thiab aeration. Cov qauv tshiab muaj qhov tsawg kawg nkaus ua rau Fluas uas yuav tsum muaj 18.2 L / (M²²²²,, nrog kev xav tau lub neej ntawm 5 xyoos hauv qab no.
Kev kwv yees peev
Kev kwv yees kev nqis peev rau ib sab (50,000 T / D) yog 22 lab RMB, nrog cov cuab yeej tseem ceeb kwv yees raws cov nqi ua lag luam tam sim no.
Post -} txhim kho kev ua tau zoo thiab ua kom zoo
Ua raws li kev ua tiav, cov txheej txheem txhim kho tau ua tiav qhov muaj peev xwm tshaj plaws ntawm 60,000 m³ / hnub thiab ib qho nruab nrab ntawm 52,000 m³ / hnub, ntsib qauv yuav tsum tau ua. Kev ua kom zoo tshaj plaws suav nrog:
1. Hloov kho cov kev tu kom huv si rau kev sib xyaw ntawm dej nraub qaum thiab tshuaj lom neeg backwash ntawm 300 mg / l.
2. Kho cov kauj ruam tu: 2 min txhua hnub dej rov qab; Rau Ceb, nres ntau lawm, tshuaj tsuag tshuaj rau 15 min, aerating rau 15 min, thiab yaug nrog dej rau 10 min.
3. Kev siv ntxhua kom huv si kom tsis txhob muaj fiber ntau tawg.
4. Saib xyuas cov tshuaj txhuam cua ua kom zoo, kho kom muaj huab cua los tiv thaiv sludge buildup.
5. Txhim kho pretreatment kom txo cov khib nyiab hauv cov theem tom qab.
