Ama-Wordliendpapermark Wastewater uqhamuka ikakhulukazi ezinqubweni zokukhiqiza ezimbili zokuphamba kanye nokuphambanisa embonini yamaphepha. Ukuphamba ukuhlukanisa imicu kusuka ezintweni ezisetshenziswayo zezitshalo, yenza uginindela, bese kufiphaza. Le nqubo izokhiqiza inani elikhulu lamanzi amdaka emaphakethe; Ukuphambana kwe-papermaking ukunciphisa, ukwakheka, cindezela, nokomisa uginindela ukwenza iphepha. Le nqubo ibuye ithambekele ekukhiqizeni amanzi amdaka emaphakethe. Amanzi amdaka aphambili akhiqizwa kwinqubo yokuphamba utshwala obumnyama notshwala obubomvu, kanye nokwahlukahlukana kukhiqiza amanzi amhlophe.
Izici eziyinhloko 1. Inani elikhulu lamanzi amdaka.2. Amanzi angcolile aqukethe inani elikhulu lama-solids amisiwe, ikakhulukazi uyinki, i-fiber, umsizi kanye nezengezo.3. Ama-SS, ama-cod, bod kanye nokunye ukungcoliswa kwamanzi amdaka aphezulu kakhulu, okuqukethwe kwe-cod kuphakeme kune-bod, futhi umbala ubumnyama.
Uhlelo Lokwelashwa Nenkinga Yezinkinga.1. Indlela yokwelashwa Indlela yokwelashwa yamanje ikakhulukazi isebenzisa i-anaerobic, aerobic, ngokomzimba kanye nokuhlangana kwenqubo yokuhlanganiswa kwenqubo yokuhlanganisa.
Inqubo yokwelashwa kanye nokugeleza: Ngemuva kokuthi amanzi angcolile angena ku-wallewater worky system, kudlula kudoti kadoti ukuze asuse ukulingana okuphezulu, kungena ku-couagition tank, futhi kukhiqize ukusabela kwe-coagation, futhi kukhiqize ukusabela kwe-cooralumin chloride kanye ne-polylamide. Ngemuva kokungena kwe-flotation, i-SS kanye nengxenye yeBoD ne-Cod emanzi angcolile kuyasuswa. I-flotation effluent ingena ekwelashweni kwe-anaerobic kanye ne-aerobic ezimbili ukwelashwa ngokususa iningi le-bod kanye ne-cod emanzini. Ngemuva kwethangi le-sedimentation yesibili, i-cod ne-chromaticty yamanzi angcolile awahlangabezani namazinga kazwelonke wokukhipha. Ukukhonjwa kwamakhemikhali kusetshenziselwa ukwelashwa okuthuthukile ukuze amanzi angcolile angahlangabezana namazinga okuphuma noma angahlangabezana namazinga okuphuma.
Izinkinga ezijwayelekile kanye nezixazululo 1) I-COD yeqa izinga. Ngemuva kokuthi amanzi angcolile aphathwa ngokwelashwa kwe-anaerobic kanye ne-aerobic biochemical, i-cod of affluent ayihlangabezani namazinga okukhishwa. Yengeze emanzini ngendlela ethile bese usabela imizuzu engama-30.
2) Womabili ama-chromatity kanye ne-cod kudlula izinga ngemuva kokuphathwa kwamanzi angcolile ngokwelashwa kwe-anaerobic kanye ne-aerobic, i-cod ye-affaent ayihlangabezani namazinga okuphuma. Isixazululo: Faka i-decolorizer ephezulu ye-Floccation Decolorizer, hlanganisa ne-decolorizer esebenza kahle, bese ekugcineni usebenzise i-polylacrylamide ukuze uthole i-floccalition kanye nezulu, ukuhlukaniswa okuqinile.
3) ngokweqile i-ammonia nitrogen I-affeent ammonia nitrogen ayikwazi ukufeza izidingo zamanje zokuphuma. Isixazululo: Faka i-ammonia nitrogen remover, uvuse noma uvuse futhi uhlanganise, bese usabela imizuzu engu-6. Esigangeni sephepha, i-afmonent ammonia nitrogen imayelana ne-40ppm, futhi i-Ammonia Nitrogen Emission Standard ingaphansi kwe-15ppm, engakwazi ukufeza izidingo zokukhishwa ezichazwe yimithetho yokuvikela imvelo.
Isiphetho Ppearmaker Urt ukwelashwa kwamanzi kufanele kugxile ekuthuthukiseni isilinganiso samanzi okuvuselela kabusha, kunciphisa ukusetshenziswa kwamanzi kanye nokuphuma kwamanzi, kufanele kuhlole izindlela ezahlukahlukene zokwelashwa kwamanzi, kufanele zihlole ngokuphelele izindlela ezisebenzayo kumanzi amdaka. Isibonelo: Indlela ye-flotation ingalulama ama-solids afudumele emanzini amhlophe, ngesilinganiso sokutakula esifinyelela kuma-95%, futhi amanzi acacisiwe angasetshenziswa kabusha; Indlela yokuvuselela amanzi angcolile ingabuyisa i-sodium hydroxide, i-sodium sulfide, i-sodium sulfate nokunye usawoti we-sodium ehlanganiswe nento e-organic emanzini amnyama. Ukungathathi hlangothi kwendlela yokwelashwa kwamanzi kuguqula inani le-PH VAUREA lamanzi angcolile; Ukuqunjelwa ukuqina noma ukugcwala kungasusa izinhlayiya ezinkulu ze-SS kumanzi angcolile; Indlela ye-Chemigical Precistage ingahlobisa; Indlela yokwelashwa yebhayoloji ingasusa i-BOD ne-CoD, esebenza ngempumelelo kakhudlwana ePharaft Paper Wall Wastewater. Ngaphezu kwalokho, kukhona ne-osmosis ehlehlisiwe, i-ultrafilytration, i-electrodialysis kanye nezinye izindlela zokuphamba kwamanzi ezihlasela ekhaya nakwamanye amazwe.
