SBR (Summressing Batch Reactor) yog tus txheej txheem uas ua tiav tau kev kho kom zoo los ntawm kev faib tawm. Nws cov ntsiab lus khiav haujlwm suav nrog cov txheej txheem ntsuas, kev tswj hwm txo qis thiab phosphorus tshem tawm kev ua kom zoo, dej zoo thiab kev txuag kev txuag.
Ntsiab lus tsis tswj kev ua hauj lwm
Cov txheej txheem SBR ua haujlwm hauv tsib theem ntawm tsib theem: Inflow, kev tawm tsam (Aeration / agement), sedimentation, tso kua dej, thiab nyob twj ywm. Lub sij hawm tsis ntawm txhua theem ncaj qha cuam tshuam rau kev kho mob nyhuv
1. Dej Inflow Theem
(1) Lub sijhawm tswj: feem ntau 0. {}}}}}} Paitioned Aboard) tuaj yeem ua kom nrawm dua qhov teeb meem organic.
(2) Dej Ntau Cov Kev Cai: Xaiv cov kev sib koom ua ke sib xyaw ua ke raws li cov khoom hloov pauv, xws li stages inflow kom txo siab kev cuam tshuam.
2. Cov tshuaj tiv thaiv theem
(1) Lub sijhawm AERATION: Yuav tsum tau hloov kho nrog rau COD / BOD load. Cov kev sim tau pom tias Aeration rau 1.5 teev thiab hypoxia rau 3 teev tuaj yeem ua tiav ib tus lej tshem tawm ntawm ntau dua 90% hauv kev lim dej hauv tsev. Wastewater muaj lub sijhawm ncua sij hawm (xws li 6-7. 5 teev) kom tiv nrog cov pa paug nyuaj.
(2) Daololtolved oxygen (ua) tswj: los ntawm kev siv cov kev sib txawv zaus {} mg / l, tsis txhob ua rau muaj kev txwv tsis pub muaj zog ntxiv rau kev siv hluav taws xob ntau ntxiv.
(3) kev cai ntawm nitrogen thiab phosphorus tshem tawm: Lwm yam Aerebic / Anaerobic / Anaerobic tej yam kev mob tom qab kev sim ua ntej los txhawb rau kev txhawb nqa denitricalification.
3. Cov theem nag lossis daus
(1) Lub sijhawm nag lossis daus: feem ntau 1-2} sijhawm. Yog tias nws yog ntev dhau lawm, nws yuav ua rau kev tawm ntawm phosphorus (xws li thaum tag nrho cov phosphorus nce siab nce tom qab 6 teev nag lossis daus).
(2) sludge interface Interface Kev soj ntsuam: Xyuas kom muaj cov dej txaus sib xyaw (feem ntau ntau dua los yog sib npaug los tiv thaiv kom tsis txhob muaj dej los ntawm nqa sludge.
4. Kev Ua Si Theem
(1) Decanter Control yuav tsum tsawg dua los yog sib npaug rau 50 hli / min kom tiv thaiv cov kev cuam tshuam ntawm cov txheej sludge txheej. Kev siv ntawm lub teb chaws decanter tuaj yeem txhim kho cov kev sib xyaw ntawm cov kua dej.
(2) Kev Txom Nyem Kev Txum Tim Dej (2) Tom qab tso dej, khaws qee cov dej kho raws li kev daws teeb meem rau kev txhim kho tom ntej los txhim kho kev cuam tshuam tiv thaiv kev cuam tshuam.
5. Cov theem kaw
(1) sludge ua kom lub zog: rov qab cov kev ua haujlwm sludge kev ua pa thaum txo cov kev xav, kev tsim kho kom tsis kam lees.
Kev cai ntawm sludge concentration thiab reflux piv
1. Kev tswj hwm ntawm sludge concentration nplai (MLSS)
(1) Qhov zoo tshaj plaws yog feem ntau tswj hwm ntawm 2000 thiab 4000 mg / l. Kev siab siab tuaj yeem ua rau lub sijhawm txiav txim siab, tab sis nws yuav tsum tau ntsuas qhov ntsuas cov pa oxygen.
(2) Txoj Kev Hloov Kho: Kho cov seem uas yog sludge tso tawm los ntawm 1 kg ss ntawm high loads thiab {}}. 75 kg ntawm cov nra hnyav.
2. Refe reflux piv txwv kev ua kom zoo
(1) RECUCTIONAL RECUX RATIO: 50% ~ 150%, Dynamically hloov los ntawm SV30 kev ntsuas.
(2) Poob Siab: Pib Reflux daifugy Thaum cov dej siab nkag mus rau hauv (xws li nce refuced refiti piv rau 300%) kom txo cov organic thauj khoom.
Kev tswj kom zoo ntawm nitrogen thiab phosphorus tshem tawm
1. Denitrification Lub Tswv Yim
(1) Luv Luv Nitrification Denitricification: Los ntawm kev siv stagation aeration (xws li prefrite hloov dua siab tshiab, cov pa roj carbon ntau thiab hluav taws xob tau txais kev cawmdim.
(2) Kev ua kom zoo ntawm cov pa roj carbon rau nitrogen ratio (C / n): kev sim tau txhim kho thaum muaj kev cuam tshuam nrog 4, thiab cov pa roj teeb yuav tsum tau ntxiv thaum nws tsis muaj peev xwm.
2. Phosphorus tshem tawm kev txhim kho
(1) Anaerobic phosphorus tso tawm: Nres ationer thaum lub sijhawm ntws thiab tswj hwm Anaerobic tej yam (ua<0.2 mg/L) through stirring to promote phosphorus release by polyphosphate accumulating bacteria.
(2) Kev Pab Choj: ntxiv hlau lossis aluminium ntsev (xws li fecl?) Ncaj ncees rau cov phosphorus tshem tawm rau cov roj ntsha phosphorus tshem tawm.
Kev ntsuas rau kev hloov pauv hloov hauv cov khoom lag luam zoo
1. Muaj Siab Kev Kho Mob Kev Kho Mob
(1) Dilution thiab Reflux: Sib tov dej huv lossis cov dej kho kom txo qis ntawm cov hluav taws xob cuam tshuam
(2) Ncua Kab Mob Aeration thiab Sludge tso tawm: Ua rau lub sijhawm Aeration Aeration mus rau ntau dua 8 teev thiab nce sludge tawm zaus kom hloov kho sludge kev ua si.
2. Supinity thiab teb rau cov tshuaj lom
(1) Sadinity Qhov: Chloride Ion Menferrations tshaj 10000 MG / L tuaj yeem tiv thaiv microbial (xws li kev kho mob lossis kev sib cais ua ntej) kom tswj cov salinity) kom tswj tau salinity.
(2) Kev Txhim Kho Kev Tiv Thaiv Pheej: Ntxiv cov roj ua siab ntev lossis siv cov pa roj carbon monoxent, ua kom luv rau lub system rov qab.
