Imishini yokuphrinta nokudaya amanzi angcolileYenzelwe ikakhulukazi futhi yathuthukiswa ukuphrinta nokudaya amanzi angcolile nge-chromaticity ephezulu nobunzima ekuhlolweni okuphezulu, kanye ne-cod ephezulu, engaxazulula ngempumelelo nobunzima bokwelashwa kwamanzi okuphrinta kwangaphambilini. Amanzi amjika okuphrinta nokudaya angakhishwa aze ahlukaniswe ngokwezinga lezokwelashwa.
Ikhwalithi yamanzi yokuphrinta nokudaya imfucumfucu iyahlukahluka ngokuya ngohlobo lwe-fiber asetshenzisiwe nokucubungula ubuchwepheshe, kanye nezinto ezingcolisayo ziyahlukahluka kakhulu. Amanzi amdaka okuphrinta nokudaya ngokuvamile anezimpawu zokuhlushwa okuphezulu okungcolile, izinhlobo eziningi, izinhlobo ezinobuthi nezilimazayo, ne-chromaticity ephezulu. Ngokuvamile, inani le-PH lokuphrinta nokudaya i-Wastewater lingu-6-10, i-Codct lingu-400-1000mg / L, bod5 yi-100-400mg / l, i-SS yi-100-200mg / L, futhi i-chromatic / l, futhi i-chromatic / l, kanye ne-chromatic
Kepha lapho inqubo yokuphrinta nokudaya, izinhlobo zemicu ezisetshenzisiwe, kanye nobuchwepheshe bokwenza ubuchwepheshe, ikhwalithi yendle izoba noshintsho olukhulu. Eminyakeni yamuva nje, ngenxa yokuthuthukiswa kwezindwangu zamakhemikhali zamakhemikhali, ukukhuphuka kwesilika nokuqedwa kwezobuchwepheshe, inani elikhulu lokuqeda ukungcolisa ama-organic anjengosayizi we-PVA (ikakhulukazi ama-phthalates), kanti nezithasiselo ezintsha zingene emanzini azophrinta nokudaya. Ukuhlushwa kwe-Codcr nakho sekukhuphuke kusuka kumakhulu we-MG / L kuya ngaphezulu kuka-2000-3000mg / L, futhi inani le-PH lifinyelele ku-11.5-12, lokhu kunciphisa isilinganiso sokususa i-CODcr sohlelo lokuqala lwebhayoloji kusuka ku-70% kuya ku-50%, noma ancishiswe.
Inani lokuthola amanzi angcolile ekuphrintiwe nokudaya imfucumfucu lincane, kepha ukungcola kwalo okungcola kuphezulu, okuqukethe imikhiqizo ehlukahlukene, ama-fiber couse imikhiqizo, ama-starch alkali, kanye nezithasiselo ezahlukahlukene. I-indle indle i-alkaline enenani le-pH azungeze ama-12. I-Wastewater enezitayela ngesitashi njengomenzeli oyisisekelo (njengendwangu yekotoni) inamanani aphezulu we-COD ne-BOD. Amanzi asuswayo angcolile ane-polyvinyl alcohol (PVA) njengomenzeli oyisisekelo (njenge-polyester ukotini we-warp yarp) ine-cod ephakeme nephansi, futhi i-bioderyadamabilibility yamanzi angcolile ayimpofu.
Amanzi amdaka okuphrinta nokudaya anenani elikhulu lamanzi amdaka abilayo kanye nokuqoqwa okuphezulu kokungcola, kufaka phakathi i-cellulose, i-wax, amakhompiyutha aqukethe, anokushisa kwamanzi anamandla nombala onsundu.
Amanzi amjika okuphrinta nokudaya anenani elikhulu lokuxubha amanzi angcolile, kepha ukungcola kungukukhanya okulula, okuqukethe ama-ejenti asele asele, amanani amancane we-acetic acid, oxalic acid, i-soosulfate, njll.
Ukuphrinta nokudaya amanzi amdaka Hurserizing Wastewater kunokuqukethwe okuphezulu kwe-alkali, ngokuqukethwe kwe-naoh kusuka ku-3% kuya ku-5%. Iningi lezitshalo zokuphrinta nokudaya zilulama i-Naoh ngokuhwamuka kanye nokuhlushwa, ngakho-ke i-lungiserewater wastewas ngokuvamile ayivaliwe. Ngemuva kokusetshenziswa okuphindaphindiwe, amanzi amdaka okugcina akhishwe kakhulu asaphila kakhulu, one-High Bod, Cod, nama-SS.
Inani lokudaya amanzi adoyiwe ekuphrintweni nokudaya likhulu, futhi ikhwalithi lamanzi liyahlukahlukana ngokuya ngodayi osetshenzisiwe. Kuqukethe ama-slurries, amadayi, izengezo, ama-surcalactants, njll., Futhi ngokuvamile i-alkaline eqinile nge-chromatic ephezulu. I-COD iphakeme kakhulu kune-bod, futhi i-biodegradeabilibility yayo imbi.
Inani lokuphrinta nokudaya imfucumfucu likhulu. Ngaphezu kwamanzi amdaka avela kwinqubo yokuphrinta, kuhlanganisa nokuthambisa kanye namanzi okuwasha amanzi awashi imfucuza ngemuva kokuphrinta. Ukuhlushwa kokungcola kuphakeme, kufaka phakathi ama-slurry, amadayi, izengezo, njll., Kanye ne-Bod ne-Cod konke kuphakeme.
Inani lamanzi amdaka asuka ekuphrintiwe nokudaya kwamanzi amdaka akwesobunxele lincane, eliqukethe ama-fiber chips, ama-resins, ama-ejenti kawoyela, kanye nama-slurries.
Ukuphrinta nokudaya amanzi amdaka Alkali Reduction Reduction Waskali kukhiqizwa ngenqubo yokunciphisa i-Alkali ye-polyester mbumbulu mbulisi, ikakhulukazi equkethe i-polyephthalic acid kanye ne-terephthalic acid kanye ne-ethylephthalic acid acid, ngokuqukethwe kwe-terephthalic acid okufika ku-75%. I-Alkaline Reduction Wastewater ayigcini nje ngokunenani eliphakeme le-PH (ngokuvamile> 12), kepha futhi linokuqoqwa okuphezulu kwezinto eziphilayo. I-codcr emanzini angcolile ikhishwe kwinqubo yokunciphisa i-Alkali ingafinyelela ku-90000 mg / l. Amakhompiyutha aphezulu aphilayo kanye namadayi athile anzima ku-biodegrade, futhi lolu hlobo lwamanzi angcolile lungokwalo olungagxili kakhulu futhi lunzima ukwenza amanzi angcolile we-organic.
Imishini yokuphrinta nokudaya yamanzi angcolile isebenzisa imisebenzi yempilo yamagciwane anaerobic kanye ne-aerobic ukuze adle ukungcoliswa kwezinto eziphilayo kumanzi amdaka. Ngasikhathi sinye, ama-biological flocculurents akhiwa ama-microorganisms amiswa futhi angcolise ama-colloccate angcucurrative asthandar, ama-adsorb ebusweni be-sludge esetshenzisiwe, anciphise izinto zokuhlanza amanzi angcolile.
Imishini ifakwe nge-underwater aeration, edonswa yi-WAMS Flow ukwakha i-aferation embaxambili. Lapho ulawula indle, indle yokukhwezwa kwendle igeleza endaweni ye-areoration kusuka phezulu kwensiza, futhi i-aerator ithola ukuvela ngaphansi kwamanzi bese icindezela ukuhamba ukuze ivuse indle. Ukukhucululwa kwendle okungenayo kuxuba ngokugcwele ngengxube yasekuqaleni, ukuzivumelanisa nezinguquko ngekhwalithi yamanzi e-inlet kuze kube sezingeni eliphakeme. I-Aerator inemisebenzi embaxambili yokugeleza kwamanzi futhi ngaphansi kwamanzi, inika amandla indle endaweni ye-aeration ukujikeleza njalo futhi yandise okuqukethwe okuchithiwe komoya. Ngenxa yokusakazwa okuqhubekayo nokugeleza kwendle kwendle kwendle, ikhwalithi yamanzi ephuzwini ngalinye endaweni ngayinye iyunifomu, futhi inombolo nezakhiwo ze-microorganisms ziyefana. Ngakho-ke, izimo zokusebenza kwengxenye ngayinye yendawo ye-aeration zicishe zingaguquguquki. Lokhu kulawula ukusabela konke okwenziwe nge-biochemical ngaphansi kwezimo ezinhle nezifanayo. Izinto eziphilayo zidilizwa kancane kancane ama-microorganisms, namanzi angcolile ahlanzwa. Ukusebenza kahle kokuhlanza kuphakeme, futhi zonke izinkomba ze-acluent zihlangabezana namazinga okuphuma kwamazinga kazwelonke "ekhiya amazinga okungcola ku-Polutants Dialing kanye ne-Gcwalisa Industry" (GB 4267-92). Ngokwezidingo zamakhasimende, izikhungo ezengeziwe ezisekelayo zinganikezwa i-oxidation eqinile ye-Ozone eqinile yokwelashwa okujulile ukuze ahlangabezane "namazinga wekhwalithi lamanzi amazinga asetshenziselwa amanzi e-Urban wallycking kanye nokusetshenziswa kwendawo yokusebenzisa kabusha.
Lo msebenzi ohlanganisiwe wokuphrinta nokudaya amanzi wastewater ukwelashwa ulungele ukwelashwa kokuphrinta okuphezulu okuphezulu nokudayiswa kwamanzi okudaya, ukudonsa amanzi angcolile, ukudaya kwendwangu yokuqeda, ukotini wendwangu kanye nokuqeda ukoya kwendwangu, ukuqeda ukotini nokotini.
