Dej phwj ib txwm ua haujlwm ntau theem ua ke cov txheej txheem uas ua ke sib txuas ntawm lub cev, roj ntsha, thiab tshuaj lom neeg ua kom huv cov dej zoo. Ntawm cov no, kev kho mob ob yog theem tseem ceeb ntawm dej phwj. Nws siv cov kev siv tshuab ntawm kev siv roj ntsha muaj roj ntsha kom tshem tawm cov kev ua yeeb yam ntau dua ntawm cov dej. Tab sis li cas raws nraim li txhua qhov haujlwm no? Hauv tsab xov xwm no, peb yuav kawm cov ntsiab lus ntawm txheej txheem kev kho vaj txheem theem kaum, suav nrog cov khoom twg hauv dej khib nyiab nws tuaj yeem tshem tawm.
Cov theem siab ntawm kev kho kom zoo
• Pretreatment:Ntxhib thiab zoo ntawm cov ntxaij vab tshaus
• Kev Kho Thawj:Tso cov hlau tso tsheb hlau luam cais cais cais 50% -60}}% ntawm tshem tawm cov khib nyiab los ntawm cov gravity setling.
• Kev kho ob theem nrab:Cov txheej txheem thev naus laus zis demrade 80% -95}% ntawm cov organic teeb meem (tseemceeb theem).
• Kev kho mob Terertiation:Pom thiab tua kab kom ua raws li effluent ua raws cai nrog cov qauv kev coj noj coj ua.
Tub ntxhais muaj nuj nqi ntawm cov txheej txheem txheej txheem qib siab
Raws li lub hauv paus theem ntawm kev kho cov dej phwj tuaj, kev kho kom tiav cov khoom siv ua kua uas tau tsim los ntawm kev kho mob thawj zaug hauv qab aerobic, anaerobic, thiab anoxic tej yam kev mob. Qhov no cuam tshuam nrog kev hloov lub txaj biofilm reactor (MBBR) reerors ua ke nrog tshem tawm cov haujlwm biochemical kom tshem tawm cov khoom siv oxychen kev thov (BOD) thiab tshem tawm cov khib nyiab. Cov ntsiab lus yog raws li hauv qab no:

Enzymatic degradation los ntawm cov kab tsuag tshwj xeeb microbial |
Kev soj ntsuam xyuas cov txheej txheem txheej txheem qib ob
1. Aerobic qhib cov txheej txheem sludge
Cov txheej txheem sludge ua kom muaj oxygen ua cov pa tawm mus rau hauv lub taub dej Aeration (piv kawg, tus kab mob fungi
Disc diffuser
Cua ntws los ntawm micropores ntawm submergeddiffusersNtawm lub tank hauv qab, tsim cov npuas zoo uas cuam tshuam los ntawm cov kua. Qhov txheej txheem no no txhim kho cov pa oxygen hloov kev ua haujlwm thiab txhawb nqa aerobic kev zom.
MBRB MBR
TusMBBR CARRIERHauv Bioreactor tuaj yeem ua kom muaj tseeb biofilm mus rau decompose teeb meem hauv dej. Lawv cov kev pabcuam saum npoo rau cov microbial txuas thiab proliferation, kom txhim kho huab hwm coj hloov kev ua haujlwm thiab microbial kev loj hlob.
2. Kev kho anoxic
Cov txheej txheem no txo cov nitrogen roj los ntawm kev tswj cov pa oxygen-depleted. Kev kho dej lwg cov nroj tsuag hluav taws xob dav txoj kev qhia txoj kev rau cov kev tshem tawm nitrogen tshem tawm.
3. Kev Kho Mob Anaerobic
Hauv cov pa oxygen kiag li, cov kab mob anaerobic decomais pov tseg rau hauv cov methane-nplua nuj biogas. Cov txheej txheem no tshwj xeeb tshwj xeeb rau kev siv cov khoom siv pov tseg kom muaj zog (Cod> 2, {} mg / l).
Tag
Tam sim no peb tau tshaj tawm cov ntsiab lus lub luag haujlwm ntawm kev kho kom huv si hauv cov dej lim dej kom huv. Nws mas tshem tawm lub cev, cov khib nyiab tshem tawm, cov pa roj ntsha, thiab pathogens los ntawm cov khoom siv xws li kev sib txawv, pab peb kom daws cov teeb meem siv pov tseg kom daws tau cov teeb meem siv pov tseg.
