Cov Khoom Siv Kho Dej Hauv Nroog Hauv Nroog Tshiab
Cov yam ntxwv ntawm cov dej phwj tuaj nyob deb nroog muaj xws li chav ua noj ua haus dej, da dej, ntxhua khaub ncaws, thiab dej tso quav tso quav.Cov dej ntws no tau tawg mus thiab tsis muaj chaw khaws khoom hauv cov chaw nyob deb nroog.Nrog rau kev yaig ntawm cov dej nag, lawv ntws mus rau hauv cov dej saum npoo av, cov dej hauv av, thiab cov dej hauv av xws li dej ntws, pas dej, kwj dej, pas dej, thiab cov pas dej.Cov ntsiab lus siab ntawm cov organic teeb meem yog cov yam ntxwv tseem ceeb.
Yuav kom tag nrho cov ntsuas dej phwj tuaj tom qab kev kho mob ua tau raws li "Kev Tshaj Tawm Txog Kev Siv Dej Num Zoo" GB8978-1996;Thawj theem qauv rau.Tom qab cov cuab yeej muab tso rau hauv kev siv, nws tuaj yeem txo cov dej phwj tuaj, txo cov pa phem ib puag ncig, thiab siv cov peev txheej dej kom ua tiav xoom paug.
Tsim cov hauv paus ntsiab lus rau cov khoom siv kho dej hauv tsev nyob deb nroog tshiab:
1. Ua raws li cov cai hauv lub tebchaws ntawm kev tiv thaiv ib puag ncig, thiab ua raws li cov cai hauv tebchaws thiab cheeb tsam, cov cai, cov qauv, thiab cov qauv;
2. Raws li lub hauv paus ntsiab lus uas cov dej ntws tau raws li qhov yuav tsum tau ua, yuav tsum tau siv zog los txuag kev nqis peev thiab ua kom tag nrho cov txiaj ntsig ntawm kev sib raug zoo, kev lag luam, thiab ib puag ncig ntawm cov dej phwj tuaj;
3. Xaiv cov txheej txheem ua tau yooj yim, yooj yim rau kev khiav lag luam thiab tswj, thiab muaj kev ruaj khov thiab txhim khu kev qha;
4. Hauv kev tsim, sim muab faib raws li kev ua haujlwm thiab siv zog rau compactness thaum ua kom muaj kev ua haujlwm zoo.
5. Sim xav txog kev ua haujlwm automation hauv kev tsim kom txo qis kev siv zog ntawm cov neeg ua haujlwm;
6. Xav txog kev ntsuas xws li kev poob siab, txo suab nrov, thiab deodorization rau kev txhawb nqa cov dej phwj tuaj kom tshem tawm cov pa phem thib ob rau ib puag ncig.
Lub hauv paus ntsiab lus rau kev xaiv cov txheej txheem ntawm cov khoom siv dej phwj hauv tsev hauv cov chaw nyob deb nroog tshiab:
Muaj ntau cov organic impurities hauv cov dej phwj hauv tsev, nrog siab CODcr thiab BOD5, thiab BOD5 / CODcr qhov tseem ceeb tshaj 0.4, qhia txog kev ua haujlwm zoo biochemical.Nws raug nquahu kom siv cov txheej txheem biochemical raws li kev kho mob.Vim muaj cov dej khib nyiab ntau, cov khoom siv faus nrog cov dej phwj tuaj yuav tsum tau siv rau kev kho biochemical.Ua ntej nkag mus rau hauv cov khoom siv biochemical, sim tshem tawm cov dej ntws thiab cov khoom loj uas raug tshem tawm ntawm cov dej phwj tuaj hauv tsev thaum lub sijhawm kho ua ntej kom ntau li ntau tau, thiab tom qab ntawd nkag mus rau hauv cov dej phwj tswj lub tank kom tsis txhob muaj kev cuam tshuam tsis zoo ntawm cov kav dej phwj tuaj.
Cov dej khib nyiab hauv tsev yog kho hauv lub septic tank.Cov dej khib nyiab da dej yog sib xyaw nrog lwm cov dej phwj tom qab tau kho los ntawm tus kws sau plaub hau thiab tom qab ntawd nkag mus rau hauv lub tank septic.Tom qab nqa los ntawm lub twj tso kua mis, nws ntws los ntawm kab sib chaws thiab nkag mus rau hauv cov kav dej phwj tuaj tom qab tshem tawm cov impurities loj.Cov dej phwj tuaj hauv lub tank tswj tau yog nqa los ntawm lub tshuab nqa nqa thiab nkag mus rau cov khoom siv dej phwj sib xyaw.Cov dej phwj tuaj hauv cov khoom siv yog kho los ntawm hydrolysis acidification, lom neeg sib cuag oxidation, sedimentation thiab lwm yam txheej txheem, thiab ces nkag mus rau hauv lub lim, Tom qab pom thiab tshuaj tua kab mob, cov effluent ua tau raws li cov qauv thiab raug tso tawm kom ntsuab.Cov sludge tsim tawm los ntawm cov sedimentation tank nyob rau hauv cov khoom siv sib xyaw yog thauj mus rau cov sludge tank hauv cov khoom siv sib xyaw los ntawm huab cua stripping.Cov sludge yog concentrated, nyob, thiab digested nyob rau hauv lub sludge tank, thiab lub supernatant yog xa rov qab mus rau lub regulating tank rau re kho nrog rau cov thawj cov dej khib nyiab.Cov sludge concentrated tsis tu ncua thiab thauj tawm los ntawm lub tsheb thauj khoom (li ib zaug txhua rau lub hlis).
Kev tshuaj xyuas cov txheej txheem ntawm cov khoom siv dej phwj hauv tsev hauv cov chaw nyob deb nroog tshiab:
① Grille
Lub grille yog tsau thiab ua los ntawm stainless hlau mesh.Teem ob coarse thiab nplua txheej kom tshem tawm cov khoom loj thiab cov impurities ntab hauv dej.
② Regulating tank thiab nqa twj tso kua mis
Vim qhov kev hloov pauv tseem ceeb hauv qhov zoo thiab qhov ntau ntawm cov dej phwj tuaj, nws yog ib qho tsim nyog yuav tsum muaj peev xwm tswj hwm lub tank kom txaus kom ruaj khov cov dej zoo thiab kom muaj nuj nqis nkag mus rau cov khoom siv dej phwj sib xyaw.
Lub tank tswj tau nruab nrog lub twj tso kua mis submersible los nqa cov dej khib nyiab mus rau cov khoom siv dej phwj sib xyaw.
③ Hydrolysis acidification tank
Lub tank hydrolysis acidification yog nruab nrog cov khoom sib xyaw ua ke.Nyob rau hauv qhov kev txiav txim ntawm hydrolysis thiab acidification microorganisms nyob rau hauv lub tank no, cov dej khib nyiab yog hydrolyzed thiab acidified rau hauv me me molecule tshuaj los ntawm macromolecular organic impurities, uas yog conducive mus rau decomposition ntawm aerobic kab mob nyob rau hauv lub contact oxidation tank.
④ Kev kho mob biochemical
Raws li cov lus hais saum toj no, cov dej phwj zoo, qhov ntau, thiab kev tso tawm, ua ke nrog cov yam ntxwv ntawm cov dej phwj tuaj.Qhov no biochemical system yuav integrate cov contact oxidation tank, sedimentation tank, sludge tank, kiv cua chav, tshuaj tua kab mob qhov hluav taws xob tank, thiab lwm yam nyob rau hauv ib tug.Txhua ntu muaj cov haujlwm sib thooj thiab txuas nrog rau ib leeg, thiab cov dej ntws zaum kawg ua tau raws li tus qauv.Cov hauv qab no tau piav qhia nyias:
Sau qhov sib cuag oxidation tank nrog fillers.Qhov qis dua yog nruab nrog lub tshuab aerator, thiab lub tshuab aeration yog ua los ntawm ABS engineering yas kav.Cov cua qhov chaw ntawm lub aeration system yog muab los ntawm ib tug tshwj xeeb configured kiv cua.
Lub sab sauv ntawm cov sedimentation tank yog nruab nrog ib tug adjustable qhov hluav taws xob weir tswj lub qhov hluav taws xob dej theem;Qhov qis dua yog nruab nrog thaj tsam conical sedimentation thiab sludge air lift device, nrog rau cov cua qhov chaw muab los ntawm tus kiv cua.Cov sludge yog thauj mus rau sludge tank los ntawm kev nqa huab cua.Lub sijhawm khaws cia ntawm sludge hauv lub tank sludge yog li 60 hnub.Cov sludge generated los ntawm lub system sedimentation yog tawm mus rau hauv lub sludge tank los ntawm huab cua nqa, qhov twg cov sludge yog concentrated, tswm thiab khaws cia.Cov kav dej aeration yog teem rau hauv qab ntawm lub tank los tiv thaiv cov sludge anaerobic digestion los ntawm generating biogas, thiab oxidize cov sludge kom txo tau tag nrho cov sludge;Concentrated sludge tsis tu ncua thiab thauj los ntawm cov tsheb thauj khoom.Lub sab sauv ntawm lub sludge tank yog nruab nrog ib tug supernatant reflux ntaus ntawv kom dhau lub supernatant mus rau lub acid hydrolysis tank.
⑤ Tshuaj tua kab mob: Ua ntej tso tawm zaum kawg, tshuaj tua kab mob chlorine dioxide.
