Ibikoresho byo gutunganya no gusiga amarangi ibikoresho byo gutunganya amazi mabicyateguwe cyane kandi cyatejwe imbere mugucapa no gusiga irangi amazi mabi hamwe na chromaticité nyinshi ningorabahizi muri decolorisation, hamwe na COD ndende, ishobora gukemura neza ibibazo bya tekiniki muburyo bwo gutunganya no gusiga amarangi.Amazi yo gucapa no gusiga irangi arashobora gusohoka kugeza mubisanzwe nyuma yo kuvurwa.
Amazi meza yo gucapa no gusiga irangi amazi yanduye aratandukanye bitewe nubwoko bwa fibre ikoreshwa nogukoresha tekinoroji, kandi ibice bihumanya biratandukanye cyane.Gucapa no gusiga irangi amazi mabi muri rusange afite ibiranga imyuka ihumanya ikirere, ubwoko bwinshi, ibinyabuzima byangiza kandi byangiza, hamwe na chromaticite.Mubisanzwe, pH agaciro ko gucapa no gusiga irangi amazi ni 6-10, CODCr ni 400-1000mg / L, BOD5 ni 100-400mg / L, SS ni 100-200mg / L, naho chromaticity ikubye inshuro 100-400.
Ariko mugihe gahunda yo gucapa no gusiga irangi, ubwoko bwa fibre yakoreshejwe, hamwe nikoranabuhanga ryo gutunganya rihinduka, ubwiza bwimyanda buzagira impinduka zikomeye.Mu myaka yashize, kubera iterambere ryimyenda ya fibre fibre, kuzamuka kwa silike yigana, no guteza imbere ikoranabuhanga ryo gusiga irangi no kurangiza, umubare munini wingorabahizi wo gutesha agaciro ibinyabuzima nkubunini bwa PVA, hydrolysate ya alkali ya silike yubukorikori (cyane cyane phthalate) ), hamwe ninyongeramusaruro nshya zinjiye mu icapiro no gusiga irangi amazi.Ihuriro rya CODCr naryo ryiyongereye kuva kuri magana mg / L kugeza hejuru ya 2000-3000mg / L, BOD5 yiyongereye kugera kuri 800mg / L, kandi agaciro ka pH kageze kuri 11.5-12, Ibi bigabanya igipimo cya CODCr cyo kuvanaho imiti yambere y’ibinyabuzima sisitemu kuva 70% kugeza kuri 50%, cyangwa no munsi.
Ingano yo kwangiza amazi mabi mu icapiro no gusiga irangi amazi mabi ni make, ariko ubwinshi bwimyanda ihumanya ni myinshi, ikubiyemo ubunini butandukanye, ibicuruzwa byangirika, fibre fibre, alkali ya krahisi, ninyongeramusaruro zitandukanye.Umwanda ni alkaline ifite pH ifite agaciro kangana na 12. Amazi yanduye hamwe na krahisi nkibikoresho nyamukuru (nk'imyenda y'ipamba) bifite COD na BOD bifite agaciro gakomeye kandi biodegradabilite.Amazi yanduye hamwe na alcool ya polyvinyl (PVA) nkibikoresho byingenzi (nka polyester ipamba yintambara yintambara) ifite COD nyinshi na BOD nkeya, kandi ibinyabuzima byangiza amazi mabi birakennye.
Gucapa no gusiga irangi amazi mabi afite amazi menshi atetse hamwe nubushyuhe bwinshi bwanduye, harimo selile, aside citricike, ibishashara, amavuta, alkali, surfactants, ibiyigize birimo azote, nibindi. Amazi y’amazi ni alkaline, hamwe nubushyuhe bwamazi menshi kandi ibara ry'umukara.
Gucapa no gusiga irangi amazi mabi afite amazi menshi yo guhumanya, ariko umwanda uroroshye cyane, urimo ibintu byangiza bisigara, aside nkeya ya acide, aside aside, sodium thiosulfate, nibindi.
Gucapa no gusiga irangi amazi mabi ahuza amazi yanduye afite alkali nyinshi, hamwe na NaOH iri hagati ya 3% na 5%.Ibiti byinshi byo gucapa no gusiga amarangi bigarura NaOH binyuze mu guhumeka no guhundagurika, bityo guhuza amazi mabi muri rusange ntibisohoka.Nyuma yo gukoreshwa inshuro nyinshi, amazi yanyuma asohotse aracyari alkaline cyane, hamwe na BOD, COD, na SS.
Ingano yo gusiga amazi mabi mugucapura no gusiga irangi ni menshi, kandi ubwiza bwamazi buratandukanye bitewe namabara yakoreshejwe.Irimo ibishishwa, amarangi, inyongeramusaruro, surfactants, nibindi, kandi muri rusange ni alkaline ikomeye hamwe na chromaticite.COD iri hejuru cyane ya BOD, kandi ibinyabuzima byayo ni bibi.
Umubare wo gucapa no gusiga irangi amazi mabi ni menshi.Usibye amazi mabi ava mubikorwa byo gucapa, harimo n'isabune n'amazi yoza amazi nyuma yo kuyacapa.Ubwinshi bwimyanda ihumanya ni myinshi, harimo ibishishwa, amarangi, inyongeramusaruro, nibindi, kandi BOD na COD byose ni hejuru.
Umubare w'amazi mabi ava mu icapiro no gusiga irangi gutunganya amazi mabi ni make, arimo fibre fibre, resin, ibikoresho bya peteroli, na slurries.
Gucapa no gusiga irangi amazi mabi ya alkali kugabanya amazi mabi aturuka mubikorwa byo kugabanya alkali ya silike yigana silike yigana, cyane cyane irimo hydrolysate ya polyester nka aside terephthalic na Ethylene glycol, hamwe na aside ya terephthalic igera kuri 75%.Kugabanya amazi mabi ya alkaline ntabwo afite agaciro ka pH gusa (muri rusange> 12), ariko kandi afite ubwinshi bwibintu kama.CODCr mumazi mabi yasohotse mubikorwa byo kugabanya alkali irashobora kugera kuri 90000 mg / L.Ibinyabuzima byinshi bya molekuline hamwe n amarangi amwe biragoye kubora biodegrade, kandi ubu bwoko bwamazi yanduye ni ubwinshi bwikibazo kandi bigoye kwangiza amazi mabi.
Ibikoresho byo gutunganya no gusiga irangi ibikoresho byo gutunganya amazi mabi bifashisha ibikorwa byubuzima bwa bagiteri ya anaerobic na aerobic kugirango bakoreshe imyanda ihumanya mumazi mabi.Muri icyo gihe, ibinyabuzima by’ibinyabuzima biterwa na mikorobe bihungabanya kandi bigahindura imyanda ihumanya kandi ihindagurika, adsorb hejuru y’imyanda ikora, itesha agaciro ibinyabuzima, kandi amaherezo igera ku ngaruka zo kweza amazi y’amazi.
Ibikoresho bifite ibikoresho byo munsi y'amazi, bigasunikwa n'amazi kugirango bigire imikorere ibiri.Iyo itunganya imyanda, imyanda itemba yinjira muri zone ya aeration kuva hejuru yigikoresho, hanyuma icyogajuru kigahinduka munsi y’amazi kandi kigasunika imigezi kugirango ikangure imyanda.Umwanda winjira winjira byihuse hamwe nuruvange rwumwimerere, uhuza nimpinduka zubwiza bwamazi yinjira muburyo bushoboka bwose.Indege ifite ibikorwa bibiri byo gutembera kw'amazi no gukwirakwiza amazi mu mazi, bigatuma imyanda yo mu karere ka aeration igenda neza kandi ikongera imyuka ya ogisijeni yashonze mu mwanda.Bitewe no kuzenguruka no gutembera kwimyanda muri zone ya aeration, ubwiza bwamazi kuri buri mwanya muri zone burasa, kandi umubare numutungo wa mikorobe ni bimwe.Kubwibyo, imiterere yakazi ya buri gice cya aeration zone irasa.Ibi bigenzura reaction ya biohimiki yose mubihe byiza kandi bisa.Ibinyabuzima bigenda byangirika buhoro buhoro na mikorobe, kandi amazi mabi arasukurwa.Gukora neza ni byinshi, kandi ibipimo byose byerekana imyanda byujuje ubuziranenge bw’ibyuka bihumanya ikirere cy’igihugu "Ibipimo byangiza imyanda ihumanya ikirere mu nganda zisiga amarangi n’imyenda" (GB 4267-92).Ukurikije ibyifuzo byabakiriya, hashobora gutangwa ibindi bikoresho byifashishwa kugirango ozone ikoreshwe cyane kugirango ihuze "Amazi meza y’amazi yo gutunganya imyanda yo mu mijyi no gutunganya ibidukikije by’amazi" (GB / T 18921-2002) ibipimo ngenderwaho byo gutunganya no gukoresha. 印染 污水 Birakoreshwa urugero rw'ibikoresho byo gutunganya:
Ibi bikoresho byogucapura no gusiga amarangi ibikoresho byo gutunganya amazi mabi birakwiriye mugutunganya amazi atandukanye yo murwego rwo hejuru, arirwo, kandi ruciriritse rwo gucapa no gusiga amazi mabi, nko gucapa no gusiga irangi amazi mabi, gusiga ubwoya no kurangiza amazi mabi, gusiga amarangi no kurangiza amazi mabi, gusiga fibre chimique no kurangiza amazi mabi, ipamba idoze hamwe nipamba ivanze irangi irangi no kurangiza amazi mabi.
