Tam sim no, feem ntau ntawm cov thev naus laus zis tshem tawm nitrogen thiab phosphorus siv hauv cov chaw kho dej phwj thoob ntiaj teb yog cov txheej txheem lom neeg, xws li txheej txheem AO, txheej txheem AAO, txheej txheem oxidation ditch, txheej txheem AB, txheej txheem SBR, thiab lwm yam ...
Cov txheej txheem no tsis zoo siab heev, thiab lawv saib yooj yim heev, tab sis nws yuav siv sij hawm ntau txoj haujlwm kom nkag siab txog lawv qhov zoo thiab qhov tsis zoo thiab sib piv qhov twg yog qhov zoo thiab qhov phem.
Txog qhov kawg no, kuv nyeem ntau cov ntawv nyeem, tab sis tom qab kev kawm,Kuv pom tias feem ntau ntawm kev sib piv ntawm cov phooj ywg tsom rau AAO, SBR, thiab oxidation ditch txheej txheem, thiab ob peb tus neeg piv AO thiab AAO txheej txheem.
Yog li ntawd,txhawm rau tshawb nrhiav cov yam ntxwv ntawm AO thiab AAO, kom nkag siab txog lawv cov kev tshem tawm ntawm COD, NH3-N, TN, thiab TP hauv cov dej phwj tuaj, nrog rau qhov kub thiab txias, qhov muaj txiaj ntsig C / N piv, thiab muaj txiaj ntsig C / P ratio. Hais txog qhov cuam tshuam ntawm nitrogen thiab phosphorus tshem tawm los ntawm cov txheej txheem, Kuv tau mus ntsib Tus Thawj Coj Wang ntawm Xinling Cov Dej Dej Kho Dej.Tus Thawj Coj Wang ncaj qha coj tawm qhov nruab nrab txhua hli ntawm cov ntsuas muaj txiaj ntsig thiab cov dej ntws tawm ntawm Xinling Cov Dej Dej Kho Dej hauv xyoo 2019 (AO txheej txheem) thiab 2021 (AAO txheej txheem), thiab muab kuv cov kev sib piv hauv qab no.

2. Kev cuam tshuam ntawm qhov kub thiab txias ntawm nitrogen thiab phosphorus tshem tawm los ntawm AAO thiab AO
2.1 Kev cuam tshuam ntawm qhov kub thiab txias ntawm COD tshem tawm los ntawm ob txheej txheem
Kub muaj qhov cuam tshuam me ntsis rau kev tshem tawm COD hauv AAO txheej txheem. Txawm hais tias qhov kub thiab txias qis dua 5 degrees Celsius, qhov kev tshem tawm ntawm COD tuaj yeem ncav cuag ntau dua 85%, uas qhia tau hais tias qhov kub thiab txias tsis cuam tshuam rau kev hloov pauv ntawm cov organic teeb meem los ntawm phosphorus accumulating kab mob.
Kev tshem tawm COD los ntawm cov txheej txheem AO zoo li yuav txo qis ntawm 5-15 degrees Celsius thaum kub nce, thiab tom qab ntawd nce ntxiv.Qhov no yuav yog vim tus naj npawb thiab cov qauv ntawm cov kab mob hauv lub cev yuav hloov pauv thaum huab cua hloov pauv ntawm qhov txias thiab sov. kev muaj peev xwm ntawm cov organic teeb meem.

2.2 Cov nyhuv ntawm qhov kub thiab txias ntawm denitrification ntawm ob txheej txheem
Undoubtedly, qhov tshwm sim ntawm qhov kub thiab txias ntawm denitrification ntawm ob txheej txheem yog qhov pom tseeb - ob qho tib si txheej txheem muaj qhov nce ntxiv hauv TN tshem tawm tus nqi raws li qhov kub thiab txias nce. Tshwj xeeb tshaj yog rau cov txheej txheem AO, thaum kub siab tshaj 15 degrees Celsius, TN tshem tawm tus nqi nce yuav luag linearly.
Yog li vim li cas, qhov ntsuas kub siab tuaj yeem txhim kho qhov kev ua haujlwm denitrification ntawm ob txheej txheem?Ntawm qhov tod tes, qhov nce hauv qhov kub thiab txias yog qhov tsim nyog rau kev loj hlob thiab kev loj hlob ntawm cov kab mob activated sludge microorganisms thiab txhim kho kev ua haujlwm ntawm nitrogen assimilation; Ntawm qhov tod tes, qhov nce hauv qhov kub thiab txias kuj tseem txhim kho cov haujlwm metabolic ntawm nitrifying kab mob thiab denitrifying cov kab mob hauv lub cev, ua rau lub cev muaj peev xwm ntawm denitrification thiab denitrification yog txhim kho.
Nws feem ntau ntseeg tau tias qhov kev loj hlob zoo tshaj plaws rau cov kab mob nitrifying yog 25-30 degrees Celsius. Thaum qhov kub qis dua 15 degrees Celsius, tus nqi nitrification txo qis, thiab kev ua haujlwm ntawm cov kab mob nitrifying kuj txo qis heev. Thaum qhov kub thiab txias qis dua 5 degrees Celsius, lub neej ua haujlwm ntawm nitrifying kab mob yuav luag nres.
Nws yog ib qho tsim nyog hais tias qee zaum txawm tias qhov kub thiab txias (tsawg dua 5 degrees), TN tshem tawm tus nqi ntawm ob lub tshuab yuav tsis qis dua 40%, uas txhais tau hais tias ob lub tshuab feem ntau cia siab rau kev sib xyaw ntawm cov kab mob hauv cov sludge activated. ntawm qhov kub thiab txias. Denitrogenation.

2.3 Cov nyhuv ntawm qhov kub thiab txias ntawm phosphorus tshem tawm los ntawm ob txheej txheem
Los ntawm qhov xwm txheej tiag tiag, phosphorus tshem tawm tus nqi ntawm cov txheej txheem AAO nce ntxiv nrog rau qhov nce ntawm qhov kub thiab txias, tshwj xeeb tshaj yog thaum kub siab tshaj 20 degrees Celsius, TP tshem tawm tus nqi yuav ruaj khov.
Qhov no yog vim hais tias tus yuam sij rau kev tshem tawm phosphorus lom yog tso siab rau phosphorus tshem tawm kev ua haujlwm ntawm phosphorus accumulating cov kab mob, thiab nce qhov kub thiab txias yog qhov zoo los ua kom cov phosphorus accumulating cov kab mob thiab txhim kho phosphorus tshem tawm tus nqi.
Txawm li cas los xij, qhov tsis tu ncua ntawm phosphorus tshem tawm los ntawm AO txheej txheem nrog kev hloov pauv kub tsis muaj zog, thiab tsis muaj kev sib raug zoo. Qhov no yog vim hais tias cov txheej txheem AO tsis muaj seem anaerobic, thiab tsis muaj qhov xwm txheej rau kev ciaj sia ntawm phosphorus accumulating kab mob. Qhov kev tshem tawm ntawm phosphorus tsuas yog nyob ntawm qhov assimilation ntawm cov kab mob, yog li qhov kub thiab txias tsis cuam tshuam rau cov assimilation ntawm cov kab mob hauv cov txheej txheem no.
