Uhlobo lwephakheji indle indle yokuhlanza amanzi Uhlelo

Uhlobo lwephakheji lokuhlanza amanzi okulahlwa kwendle Uhlelo Olufakiwe Isithombe

Incazelo emfushane:

Inqubo yeleveli 2 ye-biological oxidation yamukela i-aerator yelungelo lobunikazi, ayidingi ukufakwa kwamapayipi okuyinkimbinkimbi.Uma kuqhathaniswa nethangi le-sludge elicushiwe, linosayizi omncane kanye nokuvumelana nezimo kangcono kukhwalithi yamanzi kanye nekhwalithi yamanzi ephuma ezinzile.Akukho ukunwetshwa kwe-sludge.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isingeniso Somkhiqizo

I-tank ye-sludge ithatha indlela yemvelo ye-sedimentation, ukukhishwa okukodwa kwe-sludge kuyadingeka njalo ezinyangeni ezintathu kuya kweziyisishiyagalombili.(Ncela udaka ngekalishi lobulongwe noma ulihambise ngemva kokukhipha amanzi.)

Ngokuvamile, umuntu owabelwe ngokukhethekile akadingeki ocingweni, ukulungiswa okufanele kuyadingeka.

Ngokuvumelana nezimo okuqinile ekushintsheni kwekhwalithi yamanzi.

Ayidingi isitsha sokucindezela.I-compressor yomoya efakwe nephampu ejikelezayo kunciphisa izindleko zokutshala imali kakhulu.

Ngokusetshenziswa kwamandla okuphansi nokunakekelwa okuncane.Inqubo ye-aerobic yalesi sisetshenziswa ingahlanza iphunga lodaka.

Izinzuzo

1.Isakhiwo esibambekayo,umhlaba omncane.

2.Iyunithi eyodwa enezingxenye ezigcwele, ukusebenza kahle.

3. Hlanganisa i-nucleus nomsizi wokwelashwa, nekhwalithi yamanzi ezinzile.

4.Faka ukugeleza kwe-qravity, ukonga amandla.

5.Ukusebenza okulula, akukho ukuphathwa kochwepheshe.

Isakhiwo semishini

1. Inkambu yokwelapha esebenza kahle kakhulu ye-biochemistry: sebenzisa uhlobo olusha lwesigcwalisi, esinendawo enkulu ethize, into enamathelayo enamandla namandla okumelana nokuhlasela kahle.

2.Ichibi lokuzinza:faka i-inclind tube ukulungisa ngokusebenza kahle okuphezulu, umthamo omncane wechibi lokuzinzisa.

3. Ichibi lokuhlunga: sebenzisa okokuhlunga okukhanyayo, amandla amanzi okuwasha ngemuva, ngakho-ke asikho isidingo sepompo yokuwasha ngemuva, futhi yonga ugesi.

4. Thinta ichibi elifakwe inzalo: ukuxuba i-thimerosal namanzi angcolile ukuze uqinisekise inkomba yamanzi angaphandle.

5. Lonke uhlelo lusebenzisa ukwelashwa okudidiyelwe njenge-nucleus yemishini, iphampu esizwayo, okomshini wokuqhumisa kanye nemishini yokudosa ye-thimerosal.

Ukususwa kwe-COD nokukhiqizwa kodaka

Ngenxa nje yenani eliphezulu le-microorganism kuma-MBRs, izinga lokuthatha ukungcola lingakhuphuka.Lokhu kuholela ekonakaleni okungcono esikhathini esinikeziwe noma kumavolumu amancane e-reactor adingekayo.Uma kuqhathaniswa nenqubo evamile ecushwe udaka (ASP) ngokuvamile efinyelela ku-95%, ukususwa kwe-COD kunganyuswa kube ngu-96-99% kuma-MBR.Ukususwa kwe-COD ne-BOD5 kutholakala ukuthi kwenyuke ngokugxila kwe-MLSS.Ngaphezu kuka-15g/L ukususwa kwe-COD kucishe kuzimele ekugxilweni kwe-biomass ku->96%.

Ukugxila okuphezulu ngokunganaki kwe-MLSS akusebenzi, nokho, njengoba ukudluliswa komoyampilo kuvimbekile ngenxa ye-viscosity ephezulu kanye ne-Non-Newtonian fluid.I-Kinetics nayo ingase yehluke ngenxa yokufinyelela kalula kwe-substrate.Ku-ASP, ama-flocs angase afinyelele ku-100 μm ambalwa ngosayizi.Lokhu kusho ukuthi i-substrate ingafinyelela kumasayithi asebenzayo kuphela ngokusakazwa okubangela ukumelana okwengeziwe futhi kukhawule isilinganiso sokusabela esiphelele (ukusakazwa kulawulwa).Ukucindezelwa kwe-Hydrodynamic kuma-MBR kunciphisa usayizi we-floc (kuye ku-3.5 μm kuma-MBR aseceleni) futhi ngaleyo ndlela kukhuphule izinga lokusabela elibonakalayo.Njengaku-ASP evamile, isivuno sodaka siyehla nge-SRT ephakeme noma ukugxiliswa kwe-biomass.Udaka oluncane noma olungekho lukhiqizwa ngezinga lokulayisha udaka elingu-0.01 kgCOD/(kgMLSS d).Ngenxa yomkhawulo wokuhlushwa kwe-biomass obekiwe, amanani anjalo okulayisha aphansi angaphumela kumasayizi amakhulu amathangi noma ama-HRT amade ku-ASP evamile.
