Cov yam ntxwv ntawm cov khoom siv kho mob hauv tsev kho mob dej phwj tuaj

Cov yam ntxwv ntawm cov khoom siv kho dej hauv tsev kho mob: Cov txheej txheem ua haujlwm ntawm cov khoom siv hauv tsev kho mob dej phwj tuaj siv lub tshuab hluav taws xob tsis siv neeg, uas muaj kev nyab xeeb thiab txhim khu kev qha hauv kev ua haujlwm. Feem ntau, tsis tas yuav tsum muaj cov neeg ua haujlwm tshwj xeeb los tswj, thiab tsuas yog yuav tsum tau khaws cia hauv lub sijhawm thaum siv. Lub pas dej biochemical txais yuav txoj kev sib tiv tauj oxidation. Lub ntim ntim ntawm cov khoom siv yog tsawg, cov kab mob nyob rau hauv cov theem ntawm nws tus kheej oxidation, thiab cov sludge tsim thaum lub sij hawm ua hauj lwm yog me me. Nws tsuas yog siv sijhawm ntau tshaj peb lub hlis (90 hnub) txhawm rau tso cov av nkos (nws tuaj yeem tso dej los yog lub cev qhuav dej los ntawm lub tsheb septic thiab xa tawm mus rau hauv lub ncuav mog qab zib).

Cov txheej txheem ob-theem lom neeg sib cuag oxidation tau txais plug-flow biological contact oxidation, thiab nws cov kev kho mob zoo dua li qhov sib xyaw tag nrho lossis ob-theem serial oxidation tso tsheb hlau luam, uas tuaj yeem ua tiav kev sib cuag lom neeg. Piv nrog rau cov activated sludge tank, lub tank muaj me me ntim, muaj zog dej zoo adaptability, muaj zog tiv thaiv kev poob siab load peev, ruaj khov effluent zoo, thiab tsis muaj sludge bulking thaum lub sij hawm ua hauj lwm. Ib tug tshiab elastic peb-dimensional muab tub lim yog siv nyob rau hauv lub tank. Qhov tshwj xeeb ntawm qhov chaw ntawm qhov muab tub lim yog qhov loj, thiab cov kab mob kis tau yooj yim rau dai thiab tso cov yeeb yaj kiab. Nyob rau hauv tib cov organic load, tus nqi tshem tawm ntawm cov organic teeb meem yog siab, uas yuav txhim kho cov solubility ntawm oxygen nyob rau hauv dej. Tag nrho cov khoom siv tuaj yeem muab faus rau hauv permafrost lossis muab tso rau hauv av. Qhov saum npoo saum npoo ntawm lub cuab yeej siv tau los ua cov ntoo ntsuab lossis lwm thaj av yam tsis tas yuav tsum muaj lub tsev, cua sov thiab rwb thaiv tsev. Ntxiv nrog rau cov pa tso pa tawm siab, txoj kev deodorization ntawm faus tsev kho mob cov khoom siv dej phwj tuaj kuj muaj cov av deodorization ntsuas.

Txoj kev kho ntawm tsev kho mob cov khoom siv kho dej khib nyiab:
1. Txoj kev kho lub cev: siv cov txheej txheem membrane filtration, uas tsim nyog rau qhov xwm txheej uas cov dej hloov pauv zoo heev.
2. Txoj kev siv lub cev thiab tshuaj lom neeg: Nws yog qhov tsim nyog rau qhov xwm txheej uas cov dej tsis zoo ntawm cov dej khib nyiab hloov pauv zoo heev. Feem ntau siv txoj kev kho mob muaj xws li xuab zeb pom, activated carbon adsorption, flotation, coagulation thiab sedimentation.
Cov yam ntxwv ntawm cov txheej txheem physicochemical yog: kev siv cov hollow fiber ultrafilter rau kev kho mob, kev siv tshuab siab heev, cov qauv compact, me me hneev taw, kev ua haujlwm tsis sib xws ntawm lub cev, thiab kev tswj xyuas yooj yim.
3. Txoj kev kho mob lom neeg: Nws tuaj yeem siv los kho cov dej khib nyiab nrog cov ntsiab lus organic siab. Feem ntau, cov txheej txheem kev kho mob lom neeg xws li cov txheej txheem activated sludge, hu rau oxidation method, thiab cov khoom siv roj ntsha siv tau.

Txheej txheem txheej txheem ntawm tsev kho mob dej phwj kho khoom siv:
Cov cuab yeej feem ntau yog faus rau hauv qab ntawm qhov chaw thiab siv cov txheej txheem kev kho mob oxidation thib ob. Nws cov txiaj ntsig kev kho mob zoo dua li ntawm lub pas dej ua ke oxidation tag nrho. Nws muaj zog adaptability rau dej zoo thiab ua kom muaj kev ruaj ntseg ntawm kev kho dej. Cov cuab yeej siv hom tshiab muaj zog elastic peb-dimensional muab tub lim, thiab lub tank muaj kev ua haujlwm zoo ntawm kev tshem tawm cov organic teeb meem hauv cov dej phwj tuaj.

Tom qab kev kho oxidation, cov sludge tsim los ntawm cov khoom siv kho mob hauv tsev kho mob tsawg dua, thiab nws tsuas yog yuav tsum tau tso tawm ib zaug txhua 90 hnub. Txhawm rau kom tsis txhob muaj kev loj hlob thiab kev sib kis ntawm cov kab mob tso tawm, cov dej zoo yog kom tsis muaj menyuam. Tam sim no, cov txheej txheem tshuaj tua kab mob tau siv dav suav nrog kev tua kab mob ultraviolet, tshuaj tua kab mob chlorine dioxide thiab tshuaj tua kab mob ozone. Cov tsev kho mob yuav tsum xaiv raws li qhov zoo ntawm cov dej phwj tuaj thiab cov yam ntxwv tawm.
