Uburyo bwibanze bwo kuvura amazi yangiritse ni ugukoresha uburyo butandukanye bwo gutandukana, gukuraho no gusubiramo umwanda bikubiye mu mazi no gutakaza amazi, cyangwa kubihindura ahantu hatagira ingaruka kugirango usukure amazi.
Hariho inzira nyinshi zo kuvura imyanda, ishobora kuba ishyirwa mubyiciro bine, nicyo kuvura ibinyabuzima, aribyo kuvura ibinyabuzima, kuvura umubiri, kuvura imiti, kuvura imiti no kuvura bisanzwe.
1. Kuvura ibinyabuzima
Binyuze muri metabolism za mikorobe, imyanya migana muburyo bwibisubizo, colloide hamwe no guhagarikwa neza mumata kumazi yahinduwe mubintu bihamye kandi bitagira ingaruka. Dukurikije mikorobe zitandukanye, kuvura ibinyabuzima birashobora kugabanywamo ubwoko bubiri: kuvura ibinyabuzima bya aerobic na anaerobic kuvura ibinyabuzima.
Uburyo bwo kuvura ibinyabuzima bwa Aerobic bukoreshwa cyane mugufata ibinyabuzima byamazi. Dukurikije uburyo butandukanye, uburyo bwo kuvura ibinyabuzima byo kuvura ibinyabuzima bugabanijwemo ubwoko bubiri: gukora sludget spelge uburyo hamwe nuburyo bwa biofilm. Gukora sludge ubwabyo ni igice cyo kuvura, gifite uburyo butandukanye bwo gukora. Ibikoresho byo kuvura uburyo bwa biofilm birimo ibinyabuzima, guhuza ibinyabuzima, ibinyabuzima byanditseho ibinyabuzima, ibinyabuzima byamaraso, nibindi uburyo bwibinyabuzima nabyo byitwa uburyo busanzwe bwo kuvura ibinyabuzima. Kuvura ibinyabuzima bifatika, bizwi kandi kutigabanya ibinyabuzima, bigakoreshwa cyane mu kuvura amazi ya kano na sludge.
2. Kuvura kumubiri
Uburyo bwo gutandukanya no kugarura ibicucu byahagaritswe (harimo na firime ya peteroli hamwe namavuta yamavuta) muburyo bwamazi bushobora kugabanywa muburyo butandukanye bwo gutandukana hamwe nuburyo bwo kugumana. Ibice bivura birimo uburyo bwo gutandukanya uburemere burimo imyanda, ireremba (flotation yo mu kirere), n'ibindi, tank ya Grit, Tank yo mu kirere, Ikigega cy'indege, n'ibikoresho byayo by'indege, nibindi .; Gutandukana kwa CentriFifulika ubwabyo ni inzira yo kuvura, ibikoresho bitunganya bikoreshwa birimo Centrifuge na Hydrocyclone na Hydrocyclone, nibindi .; Uburyo bwo kugumana ecran ifite ibice bibiri byo gutunganya: Kugumana na Grid ecran no kuzengurura. Abambere bakoresha gride na ecran, mugihe uwanyuma akoresha umucangura unguruye hamwe na sngururano yuzuye, nibindi uburyo bushingiye ku ihame ry'ubushyuhe n'ubuntu bwayo birimo guhumeka no guhumeka.
3. Kuvura imiti
Uburyo bwo kuvura amazi atandukanya kandi bukuraho umwanda wuzuye kandi wa Colloidal mumazi yamazi cyangwa abahindura muburyo butagira ingaruka binyuze muburyo butagira ingaruka binyuze mumiti no kwimura rusange. Mubikoresho bivura imiti, ibice bitunganya bishingiye ku miti ya chimique yomero ni: coagulation, kutabogama, kutabogama, redix, nibindi .; Mugihe ibice bitunganyirizwa bishingiye ku iyimurwa rusange ni: Gukuramo, kwiyambura, kwamburana, intunation, ibikoresho bya eletter, n'ibindi, ibice bibiri byo gutunganya bifatanije nikoranabuhanga ryo gutandukanya. Muri bo, ishami rishinzwe kuvura ukoresheje ihererekanyabubasha rifite ibikorwa bya chimique n'ibikorwa bifitanye isano, bityo birashobora no gutandukana nuburyo bwo kuvura imiti no kuba ubundi buryo bwo kuvura, bwitwa uburyo bwumubiri, bwitwa uburyo bwumubiri.
ishusho
Inzira isanzwe yo kuvura
1. Devereas amazi
Ibipimo byanduye nkibintu byamavuta, codcr na bod5 mumyanda idahwitse ni ndende cyane. Uburyo bwo kuvura burimo gukuramo aside, centrifugation cyangwa gukuramo umwenda. Uburyo bwo gukuramo Acide burakoreshwa cyane, yongeraho H2SO4 kugirango ahindure agaciro ka 3-4 kugirango ahinduke, kandi akize kuri 4-60 t kuri 45-60 t kuri 2-60 t kuri buri 2-60 areremba kugirango akore urwego rurerure. Gusubirana amavuta birashobora kugera kuri 96%, kandi gukuraho CoDCR irenga 92%. Mubisanzwe, kwibanda kuri peteroli mumazi yizitizi ni 8-10g / l, hamwe na peteroli kwibanda kumavuta mumazi biri munsi ya 0.1 g / l. Amavuta yagaruwe aratunganijwe kandi ahindurwa muri acide zivanze zishobora gukoreshwa mugukora isabune.
2. Kudamunuka no gukuraho umusatsi
Kugabanuka no gukuraho umusatsi birimo proteyine, lime, sodium sulfide, yahagaritswe kuri code zose, 28% ya CODCR yose, 92% Yuzuye SS-, na 75% ya SS yose. Uburyo bwo kuvura burimo accide, imvura ya chimical na okiside.
Uburyo bwo gucika bugufi bukoreshwa mugukora umusaruro. Ukurikije igitutu kibi, ongeraho H2SO4 kugirango uhindure PH agaciro ka 4-4.5, ubyare gaze ya H2S, kubikuramo Naoh igisubizo, hanyuma uyinjizeho igisubizo cya alkali kugirango ukoreshe. Proteine yoroshye yandujwe mumata kumazi yarushije urunone, yogejwe, yumye. guhinduka ibicuruzwa. Igipimo cyo gukuraho sulfide kirashobora kugera kurenga 90%, kandi coDCR na SS bigabanuka na 85% na 95%. Igiciro cyacyo ni gito, ibikorwa byumwanda biroroshye, byoroshye kubigenzura, kandi umusaruro wabyo wagabanijwe.
3. Chrome itwara imyanda
Umwanya munini wa Chrome ugabana imyanda ni ibyuma biremereye cr3 +, kwibanda cyane ni 3-4g / l, hamwe na pH agaciro ka acidique. Uburyo bwo kuvura burimo imvura ya alkali kandi busubiramo. 90% bya kaneri yo mu rugo Koresha uburyo bwo kugwa bwa Alkali, ongeraho Lime, sodium hydroxide, magnesium oxide yo guswera kwa chromium, zirashobora gukoreshwa no gutaka kwa chromium, zirashobora gukoreshwa muburyo bwo gutaka nyuma yo gushonga muri acide sulfuric.
Mugihe cyo kubyitwaramo, agaciro ka PH ni 8.2-8.5, kandi imvura nibyiza kuri 40 ° C. Umubyeyi wa Alkali ni Magnesium Oxide, igipimo cyo kugarura cya Chromium ni 99%, hamwe na misa ya chromium muri efroluent iri munsi ya 1 mg / l. Ariko, ubu buryo bukwiranye na tanne nini nini, hamwe numwanda nko gufata amavuta na poroteyine mubyo ya recycled bizagira ingaruka kumitekerereze.
4. Amazi meza
4.1. Sisitemu yo Kwitegura: Ahanini ikubiyemo ahanini ibikoresho byo kuvura nka grille, kugenzura ikigega, tank ya tank hamwe na tank ya flotation. Kwibanda ku bintu kama kandi bihagarikwa kuri mwese mu mazi ya kanseri ari ndende. Sisitemu yo guhitamo ikoreshwa muguhindura ingano y'amazi n'amazi; Kuraho SS nahagaritswe! Mugabanye igice cyumutwaro wumwanda no gukora ibintu byiza byo kuvura ibinyabuzima nyuma.
4.2. Sisitemu yo kuvura ibinyabuzima: ρ (CoDCR) yita kumazi ya karnery muri rusange ni 3000-4000 MG / L, ρ (bod5) / m (codcr) agaciro ni 0.3-0.6, bikwiranye no kuvura ibinyabuzima. Kugeza ubu, umwobo wa okiside, sbr na okiside itunganye na okiside nyinshi zikoreshwa cyane mubushinwa, mugihe indege ya aefilm, icyicaro), igitanda cya SBBR), ibitanda bya SBBR)
