Cov peb hom anaerobic reactors no sawv cev rau kev hloov pauv ntawm anaerobic biological kho tshuab los ntawm theem pib mus rau kev sib koom ua ke. Peb tuaj yeem xav txog lawv li "qhov yooj yim," "ua kom zoo dua," thiab "super" qauv.
Kev piav qhia ntxaws ntawm Cov Qauv Sab Hauv thiab Cov Cai Ua Haujlwm
1. UASB (Basic Model: Single-Stage Reaction)
* Internal Structure: Cov qauv yooj yim tshaj plaws, nws tuaj yeem suav tias yog ib qho - txheej cov tshuaj tiv thaiv tank. Cov dej khib nyiab nkag los hauv qab thiab ntws mus rau ntawm lub txaj sludge. Ib qho -txheej peb-theem cais yog nyob rau saum toj, lub luag haujlwm rau cais cov biogas, sludge, thiab dej.
* Txoj Cai Ua Haujlwm: Nws tsis muaj qhov yuam kev ncig; nws cia siab rau tag nrho cov natural mixing ntawm lub influent flow thiab generated biogas. Sludge tsim "sludge txaj" nyob rau hauv qab ntawm lub reactor, uas yog decomposed raws li cov dej khib nyiab hla.
* Cov yam ntxwv: Cov qauv yooj yim, tus nqi qis, tsis muaj hluav taws xob sab nraud yuav tsum tau, tab sis qhov sib xyaw ua haujlwm feem ntau yog nruab nrab, nquag mus rau qhov chaw tuag, thiab muaj qhov tsis muaj zog poob siab.
2. EGSB (Enhanced Version: High-Flow-Rate Expanded Bed)
* Internal Structure: Raws li UASB, lub tank ua kom siab dua thiab slimmer (siab siab - rau - txoj kab uas hla). Nws cov yam ntxwv tseem ceeb tshaj plaws yog kev suav nrog cov kab hluav taws xob sab nraud (lub twj tso kua mis rov qab), uas tso cov dej ntws rov qab mus rau qhov nkag.
* Txoj Cai Ua Haujlwm: Lub twj tso kua mis tawm sab nraud yuam kom cov dej ntws nce siab tshaj plaws (nce txog 3-10 m / h), muab tag nrho cov sludge txaj rau hauv "nthuav" lossis txawm tias "fluidized" lub xeev. Qhov kev ntxhov siab hnyav no tshem tawm cov chaw tuag, ua kom muaj kev sib cuag zoo ntawm cov dej khib nyiab thiab cov sludge.
* Nta: Tsis tshua muaj huab hwm coj hloov pauv tau zoo thiab muaj zog poob siab, tab sis vim qhov xav tau rau lub twj tso kua mis sab nraud, nws cov kev siv hluav taws xob ua haujlwm yog qhov siab tshaj ntawm peb.
3. IC (Super Version: Muab ob npaug rau-Txheej Internal Circulation)
* Internal Structure: Qhov tseem ceeb yog ob lub UASB reactors stacked vertically, featuring ob -theem peb-phase separator. Nws cov qauv tseem ceeb muaj xws li lub hauv paus biogas riser (upflow yeeb nkab) thiab sludge xa rov qab yeeb nkab (downflow yeeb nkab).
* Txoj Cai Ua Haujlwm: Qhov loj ntawm biogas tsim nyob rau hauv qab thawj cov tshuaj tiv thaiv chamber ua zoo li lub tshuab nqa huab cua, kos cov sludge - dej sib tov rau saum ntawm cov yeeb nkab riser. Tom qab degassing rau saum, cov sludge - cov dej sib tov cia li poob rov qab mus rau hauv qab ntawm cov yeeb nkab xa rov qab, tsim lub zog sab hauv uas tsis tas yuav muaj lub zog sab nraud. Sab saum toj thib ob cov tshuaj tiv thaiv chamber ces "zoo- txheej txheem" cov dej khib nyiab.
* Nta: Muaj peev xwm ua tau zoo heev, tsis tshua muaj hneev taw (vim nws qhov siab), lub zog poob siab tshaj plaws (lub voj voog sab hauv yuav ua rau lub zog muaj zog), thiab tsis tas yuav tsum muaj lub twj tso kua mis sab nraud, ua rau kev siv hluav taws xob tsawg.
Daim Ntawv Pov Thawj Cov Cai thiab Cov Lus Pom Zoo Xaiv
1. Application Conditions of UASB
* Cov xwm txheej siv tau: Tsim nyog rau cov dej khib nyiab qis mus rau nruab nrab nrog cov dej ruaj khov thiab muaj nuj nqis (xws li kev ua zaub mov thiab cov dej tua tsiaj).
* Cov Nyiaj Txiag thiab Qhov Chaw: Tsim nyog rau cov haujlwm uas muaj peev txheej tsawg thiab cov kev cai nruj me ntsis rau hauv pem teb.
* Cov kev txwv: Tsis haum rau kev kho qis - qhov kub thiab txias, qis - cov dej khib nyiab los yog cov dej khib nyiab uas muaj cov tshuaj lom vim nws muaj peev xwm sib tov thiab poob siab.
2. Daim Ntawv Thov Cov Cai ntawm EGSB
* Cov xwm txheej siv tau: Tshwj xeeb yog tsim nyog rau qis -concentration, recalcitrant organic wastewater, los yog kev kho dej khib nyiab nyob rau hauv qis - qhov kub thiab txias.
* Tshwj xeeb Dej Zoo: Vim nws qhov siab - nrawm nrawm, nws kuj muaj qhov hloov tau zoo rau cov dej khib nyiab uas muaj cov khib nyiab tshem tawm (SS).
* Cov kev txwv: Yog tias qhov project no muaj kev cuam tshuam rau cov nqi hluav taws xob ua haujlwm, kev siv hluav taws xob siab ntawm EGSB (sab nraud ncig lub twj tso kua mis) yog tus nqi los xav txog.
3. Daim Ntawv Thov Cov Cai ntawm IC
* Cov xwm txheej siv tau: Tshwj xeeb tsim los rau ultra- siab concentration, loj- ntim cov dej khib nyiab (xws li ntawv, cawv, citric acid, thiab cov dej khib nyiab tshuaj, nrog COD mus txog kaum lossis ntau pua txhiab).
* Site Constraints: Yog tias koj thaj chaw cog muaj tsawg heev, IC reactor yog thawj qhov kev xaiv vim tias nws txoj kev kho mob yog 3-5 npaug ntawm UASB ntawm tib lub ntim.
* Dej Zoo Hloov Pauv: Thaum muaj qhov hloov pauv loj hauv cov dej muaj txiaj ntsig zoo lossis kev poob siab, qhov tsis siv neeg sab hauv kev ua haujlwm dilution ntawm IC tuaj yeem ua haujlwm ruaj khov.
Hauv cov ntsiab lus:
* Rau cov nqi tseem ceeb-kev ua tau zoo thiab cov dej yooj yim dua, xaiv UASB;
