Lawv lub luag haujlwm tseem ceeb hauv kev kho dej
Cov txheej txheem aerobic
(1) Tshem tawm cov organic:Aerobic microorganisms hloov cov organic teeb meem (bod) nyob rau hauv cov pa khib nyiab (CO
(2) Tshem tawm ntawm ammonia nitrogen (nitration):Nitrifify cov kab mob nyob rau hauv lub aerobic txheej txheem hloov ammonia nitrogen (NH₄⁺) nyob rau hauv dej lwg rau hauv nitrate (No₃⁻). Qhov no tau muab faib ua ob theem:
• Ammonia-oxidizing cov kab mob hloov ammonia nitrogen rau hauv Nitrite (No₂⁻).
• Nitrite-oxidizing cov kab mob txuas ntxiv hloov chaw nitrite rau hauv nitrate (No₃⁻).
(3) tshem tawm ntawm phosphorus:Nyob rau hauv aerobic tej yam kev mob, qee cov kab mob phosphorus-actos tau nqus tau phosphative hauv cov kua tsib, yog li txo cov ntsiab lus phosphorus hauv cov dej khib nyiab. Txawm li cas los xij, qhov no yuav tsum tau ua ke nrog cov txheej txheem anaerobic kom ua tiav.
Anoxic txheej txheem
(1) Tshem tawm ntawm nitrate (denitricification):Cov tub ntxhais ntawm lub anoxic cov txheej txheem yog denitricification, uas yog, txo nitrate (No₃⁻) rau hauv nitrogen roj (n₂).
(2) Siv rau cov khoom siv ntxiv rau cov khoom siv ntxiv:Hauv cov txheej txheem denitrification, nws tuaj yeem siv cov organic muaj teeb meem hauv dej los ua cov pa roj carbon, txo cov nqi ua haujlwm.
(3) synero synergistic nitrogen tshem tawm:Thaum ua ke nrog cov txheej txheem aerobic, cov txheej txheem no tuaj yeem tsim tus A / O (AEROBIC / AO (AERACHIC / AEROBIC).
Cov txheej txheem anaerobic
(1) kev coj tsis zoo ntawm cov kev xav zoo organic:Anaerobic microorganisms decompose cov complex organic muaj teeb meem thiab thaum kawg hloov nws mus rau hauv Methane (chi) thiab carbon dioxide (Coos).
(2) kev tsim tawm ntawm biogas:Cov txheej txheem anaerobic tsim biogas thaum lub sij hawm daws teeb meem organic. Nws lub ntsiab lus tseem ceeb muaj methane thiab carbon dioxide.
(3) Tshem tawm ntawm ib feem ntawm cov khib nyiab tshem tawm:Nws tshem tawm ib feem ntawm cov khib nyiab (SS) nyob rau hauv wastewater los ntawm kev kos duab thiab nag lossis daus ntawm cov kab mob me, yog li txhim kho lub effluent zoo.
Yuav xaiv cov txheej txheem no rau koj daim ntawv thov
Xaiv cov txheej txheem kev kho kom tsim nyog kom txiav txim siab los txiav txim siab ntau yam, suav nrog cov hom dej pov tseg, nrog cov nqi ua haujlwm, thiab cov chaw haujlwm. Nov yog qee cov lus qhia rau xaiv cov txheej txheem:
1. Cov Hom Phiaj Kho Mob:Txhua txheej txheem kev kho mob muaj lub luag haujlwm sib txawv. Yog tias koj lub hom phiaj ua haujlwm yog tshem tawm cov organic, koj tuaj yeem xaiv cov txheej txheem kev kho mob aerobic. Yog tias nws yog rau Nitrogen tshem tawm, koj tuaj yeem xaiv cov txheej txheem kho anoxic. Thiab kev kho mob anaerobic feem ntau yog siv rau cov tshuaj organic ntau.
2. Cov nqi ua haujlwm:Txoj haujlwm ua haujlwm ntawm Aerobic kev kho mob yog tus txheej txheem siab, feem ntau yog vim muaj pa oxygen txaus kom muab. Thaum lub sijhawm ua haujlwm raug nqi ntawm cov txheej txheem anaerobic yog qhov tsawg. Txij li nws tsis tas yuav muab cov khoom siv los muab cov pa oxygen thiab tuaj yeem tsim biogas raws li lub zog hluav taws xob.
3. Cov Lus Qhia:Lub aerobic kev kho mob yuav tsum muaj chaw ntau dua thiab cov khoom siv khoom siv ntau. Vim tias nws yuav tsim ntau yam sludge thaum lub sij hawm kev kho dej, thiab cov khoom siv ntxiv rau kev tu thiab tsheb thauj mus los. Tib yam yog qhov tseeb rau cov txheej txheem anaerobic, uas yuav tsim biogas.
4. Ua ke cov txheej txheem:Qee zaum, koj kuj tuaj yeem muab peb cov txheej txheem no ua ke rau siv. Raws li peb cov kev ntsuam xyuas, lawv tuaj yeem txhim kho cov dej zoo thiab txo cov khoom lag luam ntawm cov khoom siv ua haujlwm sludge.
