Imishini yokunyathelisa nokudaya amanzi angcolileiklanyelwe futhi ithuthukiswe ngokuyinhloko ukuphrinta nokudaya amanzi angcolile nge-chromaticity ephezulu kanye nobunzima bokukhipha umbala, kanye ne-COD ephezulu, engaxazulula ngempumelelo ubunzima bezobuchwepheshe kunqubo yangaphambilini yokunyathelisa nokudaya amanzi angcolile.Amanzi angcolile okuphrinta nokudaya angakhishwa aze afike ezingeni elijwayelekile ngemva kokwelashwa.
Izinga lamanzi lokunyathelisa nokudaya amanzi angcolile liyahlukahluka kuye ngohlobo lwefayibha esetshenzisiwe kanye nobuchwepheshe bokucubungula, futhi izingxenye ezingcolisayo ziyahlukahluka kakhulu.Ukuphrinta nokudaya amanzi angcolile ngokuvamile anezici zokugxilisa ukungcola okuphezulu, izinhlobo eziningi, izinto ezinobuthi neziyingozi, kanye ne-chromaticity ephezulu.Ngokuvamile, inani le-pH lokuphrinta nokudaya amanzi angcolile lingu-6-10, i-CODCr ingu-400-1000mg/L, i-BOD5 ingu-100-400mg/L, i-SS ingu-100-200mg/L, kanti i-chromaticity yizikhathi ezingu-100-400.
Kodwa lapho inqubo yokunyathelisa nokudaya, izinhlobo zemicu esetshenziswayo, nobuchwepheshe bokucubungula kushintsha, izinga lokukhucululwa kwendle liyoba noshintsho olukhulu.Eminyakeni yamuva nje, ngenxa yokuthuthukiswa kwezindwangu ze-fiber zamakhemikhali, ukukhuphuka kosilika wokulingisa, kanye nokuthuthuka kobuchwepheshe bokudaya nokuqeda, inani elikhulu lobunzima bokunciphisa ama-organic compounds afana nosayizi we-PVA, ama-alkali hydrolysates kasilika wokufakelwa (ikakhulukazi ama-phthalates). ), futhi izithasiselo ezintsha sezingenile ekunyatheliseni nasekudayeni amanzi angcolile.Ukugxiliswa kwe-CODCr nakho kwenyukile kusuka kumakhulu mg/L kuya ngaphezu kuka-2000-3000mg/L, i-BOD5 inyuke yaba ngaphezu kuka-800mg/L, futhi inani le-pH selifinyelele ku-11.5-12, Lokhu kwehlisa izinga lokususwa kwe-CODCr lokwelashwa kwasekuqaleni kwebhayoloji. uhlelo lusuka ku-70% luye cishe ku-50%, noma ngaphansi.
Inani lokukhishwa kwamanzi angcolile ekunyatheliseni nasekudayeni amanzi angcolile lincane kakhulu, kodwa ukugcwala kokungcola kuphezulu, okuqukethe amasayizi ahlukahlukene, imikhiqizo yokubola kosayizi, ama-fiber chips, isitashi alkali, nezithasiselo ezihlukahlukene.Indle ine-alkaline enenani le-pH elicishe libe ngu-12. Amanzi angcolile akhishwayo anesitashi njenge-agent enkulu yokulinganisa (njengendwangu kakotini) anamanani aphezulu e-COD ne-BOD kanye nokubola okuhle kwemvelo.Amanzi angcolile enziwe nge-polyvinyl alcohol (PVA) njenge-ejenti yokulinganisa eyinhloko (njenge-polyester cotton warp yarn) ane-COD ephezulu kanye ne-BOD ephansi, futhi ukubola kwe-biodegradability kwamanzi angcolile kubi.
Ukuphrinta nokudaywa kwamanzi angcolile anenani elikhulu lamanzi angcolile abilayo kanye nokugcwala okuphezulu kokungcola, okuhlanganisa i-cellulose, i-citric acid, i-wax, uwoyela, i-alkali, ama-surfactants, izinhlanganisela eziqukethe i-nitrogen, njll. Amanzi angcolile ane-alkaline enamandla, anezinga lokushisa eliphezulu lamanzi futhi umbala onsundu.
Amanzi angcolile okuphrinta nokudaywa anenani elikhulu lamanzi angcolile agcotshwa nge-bleaching, kodwa ukungcola akulula, okuqukethe ama-ejenti asele e-bleaching, amanani amancane e-acetic acid, i-oxalic acid, i-sodium thiosulfate, njll.
Amanzi angcolile okuphrinta nokudaya amanzi angcolile ane-alkali ephezulu, enokuqukethwe kwe-NaOH okusuka ku-3% kuya ku-5%.Izitshalo eziningi zokuphrinta nokudaya zibuyisela i-NaOH ngokuhwamuka nokugxilisa ingqondo, ngakho-ke amanzi angcolile e-mercerizing ngokuvamile awavamile ukuchithwa.Ngemva kokusetshenziswa okuphindaphindiwe, amanzi angcolile okugcina akhishiwe asene-alkaline kakhulu, ane-BOD ephezulu, i-COD, ne-SS.
Inani lamanzi angcolile okudaya ekunyatheliseni nasekudayeni likhulu uma kuqhathaniswa, futhi izinga lamanzi liyahlukahluka kuye ngokuthi odayi abasetshenziswayo.Iqukethe ama-slurries, odayi, izithasiselo, ama-surfactants, njll., futhi ngokuvamile i-alkaline eqinile ene-chromaticity ephezulu.I-COD iphakeme kakhulu kune-BOD, futhi i-biodegradability yayo impofu.
Inani lokuphrinta nokudaywa kwamanzi angcolile likhulu uma kuqhathaniswa.Ngaphezu kwamanzi angcolile avela ohlelweni lokunyathelisa, kuhlanganisa nensipho namanzi okugeza amanzi angcolile ngemva kokuphrinta.Ukugcwala kokungcola kuphezulu, okuhlanganisa i-slurry, odayi, izithasiselo, njll., kanti i-BOD ne-COD konke kuphezulu.
Inani lamanzi angcolile asuka ekuphrinteni nasekudayeni amanzi angcolile lincane uma kuqhathaniswa, eliqukethe ama-fiber chips, ama-resin, ama-oyili, nama-slurries.
Ukuphrinta nokudaywa kwamanzi angcolile okunciphisa i-alkali amanzi angcolile akhiqizwa ngenqubo yokunciphisa i-alkali kasilika wokulingisa we-polyester, ikakhulukazi aqukethe i-polyester hydrolysates njenge-terephthalic acid ne-ethylene glycol, enokuqukethwe kwe-terephthalic acid efika ku-75%.Amanzi angcolile okuncishiswa kwe-alkali awagcini nje ngokuba nenani eliphezulu le-pH (ngokuvamile>12), kodwa futhi anenani eliphezulu lezinto eziphilayo.I-CODCr emanzini angcolile akhishwa ohlelweni lokunciphisa i-alkali ingafinyelela ku-90000 mg/L.Izinhlanganisela zamangqamuzana aphezulu kanye nodayi abathile kunzima ukuwohloka kwemvelo, futhi lolu hlobo lwamanzi angcolile lungolwakugxilwa kakhulu futhi kunzima ukucekela phansi amanzi angcolile ezinto eziphilayo.
Imishini yokunyathelisa nokudaya amanzi angcolile isebenzisa imisebenzi yempilo yebhaktheriya ye-anaerobic kanye ne-aerobic ukuze idle ukungcola kwemvelo emanzini angcolile.Ngasikhathi sinye, ama-biological flocculent akhiwa ama-microorganisms adala ukuqina futhi antante ukungcola okumisiwe okumisiwe kanye ne-colloidal organic, adsorb phezu kodaka olucushiwe, alulaze izinto eziphilayo, futhi ekugcineni afinyelele umphumela wokuhlanza amanzi angcolile.
Izinto ezisetshenziswayo zifakwe umoya ongaphansi kwamanzi, ophushwa ukugeleza kwamanzi ukuze kwakheke ukusebenza okumbaxambili komoya.Lapho kulungiswa indle, indle igelezela endaweni yokungenisa umoya isuka phezulu kwedivayisi, futhi i-aerator ingena ngaphansi kwamanzi bese iphusha ukugeleza ukuze inyakazise indle.Indle engenayo ngokushesha ixubana ngokugcwele nengxube yasekuqaleni, ivumelane nezinguquko zekhwalithi yamanzi okungena ezingeni eliphezulu kakhulu.I-aerator inemisebenzi emibili yokugeleza kwamanzi kanye nokungenisa umoya ngaphansi kwamanzi, okwenza indle esendaweni yokungenisa umoya ijikeleze njalo futhi andise okuqukethwe komoyampilo oncibilikisiwe endle.Ngenxa yokugeleza okuqhubekayo nokugeleza kwendle endaweni yokungenisa umoya, ikhwalithi yamanzi endaweni ngayinye endaweni iyafana, futhi inombolo nezakhiwo zama-microorganisms ziyafana ngokuyisisekelo.Ngakho-ke, izimo zokusebenza zengxenye ngayinye yendawo yokungenisa umoya zicishe zifane.Lokhu kulawula konke ukusabela kwe-biochemical ngaphansi kwezimo ezinhle nezifanayo.Izinto eziphilayo zonakaliswa kancane kancane ama-microorganisms, futhi amanzi angcolile ayahlanzwa.Ukusebenza kahle kokuhlanzwa kuphezulu, futhi zonke izinkomba zamanzi angcolile zihlangabezana nezindinganiso zokukhishwa kwezwe "Amazinga Okukhishwa Kwezinto Ezingcolisayo Embonini Yokudaya Ngendwangu kanye Nokuqeda" (GB 4267-92).Ngokwezidingo zamakhasimende, ezinye izindawo ezisekelayo zinganikezwa ukwelashwa okujulile kwe-oxidation ye-ozone ukuze kuhlangatshezwane namazinga "Ekhwalithi Yamanzi Okusebenzisa kabusha Amanzi Angcolile E-Urban and Landscape Environment Water" (GB/T 18921-2002) ukuze kugaywe kabusha futhi kusetshenziswe.印染污水Kuyasebenza. ububanzi bemishini yokucubungula:
Le mishini edidiyelwe yokunyathelisa nokudaya amanzi angcolile ilungele ukwelashwa kwamanzi angcolile ahlukahlukene aphezulu, aphakathi nendawo, naphansi, njengokuphrinta okunithiwe nokudaya amanzi angcolile, ukudaya uboya nokuqeda amanzi angcolile, ukudaya usilika nokuqeda amanzi angcolile, ukudaya kwamakhemikhali amakhemikhali. kanye nokuqeda amanzi angcolile, ukotini olukiweyo kanye nendwangu ehlanganisiwe kakotini ukudaya nokuqeda amanzi angcolile.
