Siyini Isilo Sokugcina Udaka Lwendlule?
Isilo sokugcina udaka lwendlule siyisitsha esikhethekile, esime mpo esiyisilinda esakhelwe ngokukhethekile ukugcina isikhashana inqwaba yodaka olomile (udaka oluyisinkwa) olukhiqizwa ngesikhathi sokuhlanza indle emadolobheni nasezimbonini.
Emizimbweni yokuhlanza amanzi angcolile (WWTPs), izilulu zokugcina udaka lwendle zisebenza njengezinto ezibalulekile zokusebenza phakathi kwemishini eqhubekayo yokomisa (njengezihlungi zamabhande noma ama-centrifuge) kanye nezinto zokuthutha eziya ngaphandle (njengamaloli athutha udaka ukuya emasimini, ukuvundisa, noma ezindaweni zokushisa). Ngenxa yokuthi udaka lwendle olomisiwe lunamathela, luyaphila, lusinda, futhi lugqwala, izilulu zokugcina udaka lwendle zidinga ubunjiniyela obuqinile bezakhiwo, izindawo ezingaphakathi ezingenamathela ezenziwe ngobuchwepheshe, kanye nezinhlelo zokulawula iphunga ezingangeni moya.
Izici Eziyinhloko Zobunjiniyela Nokusebenza
Ukuphatha nokugcina udaka lwendlule olomile emadolobheni kuqukethe izinselele eziyingqayizivele zemishini nezemvelo uma kuqhathaniswa nokugcina izimpushana ezomile noma uketshezi olujwayelekile. Izilo zokugcina udaka lwendlule zihlanganisa izingxenye eziningi ezikhethekile zobunjiniyela:
·
Izingaphakathi ezingagqwali futhi ezinganamatheli: Udaka lwendle luqukethe ama-asidi e-organic, umswakama, namagesi agqwalisayo (anjenge-hydrogen sulfide). Amathangi akhiwa kakhulu nge-Glass-Fused-to-Steel (GFS) noma insimbi engagqwali ephezulu ukuvimbela ukugqwala kwe-electrochemical nokuqinisekisa ukuthi ujeke wodaka olunamathelayo lushelela kalula ezindongeni.

Izindlela Zokukhipha I-Live-Bottom: Ngokungafani nezinto eziphuma kalula, ujeke wodaka olomisiwe uyahlangana, unamandla okunamathela, futhi uvame ukugcwala noma ukuminyana. Amasilo anezinhlelo ezikhethekile zokukhipha i-live-bottom—njengamafreyimu aslayidayo e-hydraulic, izikrudu eziningi ezijikelezayo, noma ama-auger asebenzayo—aphusha ngamandla udaka uye emgwaqweni wokuphuma.

·
Ukuvala Okungangeni Moya Nokulawula Iphunga: Ukubola kodaka kukhiqiza amaphunga amabi namagesi abamba ukushisa. Ama-silo anezimpahla ezivalwe ngokuphelele kanye nezindawo zokukhipha umhwamuko ezixhunywe kuma-biofilter, ama-carbon scrubber, noma izinhlelo zokushisa ukuze kuvinjwe ukukhishwa okungalawuleki.
·
·
Amandla Esakhiwo Aqinile: Kuklanyelwe ukumelana nokucindezela okuphezulu okuvundlile nokume mpo okwenziwa izinto ezinamandla eziphilayo eziwubunzima, ngokuvamile zakhiwa ngensimbi eqinile eboshwe ngezikulufu noma izakhiwo zikakhonkolo eziqinisiwe.

Ithebula Lokuqhathanisa: Izindlela Zokugcina Udaka Lwendlule
Indlela Yokugcina | Ukuvinjelwa Kwephunga Negesi | Ukuthembeka Kokukhipha (Ukuvimbela Ukugcwala) | Ukumelana Nokugqwala Nokugqokwa | Indawo Nokusetshenziswa Komhlaba |
I-Glass-Fused-to-Steel (GFS) Silo ene-Live Bottom | Kuhle Kakhulu (Kuvalwe ngomoya ngokuphelele nokuhlanza amaphunga okusebenza) | Phezulu (Ifakwe izakhiwo zokushibiliza ezinamandla kanye nezinto zokukhipha izikulufu) | Ephakeme (Ingaphezulu lengilazi elingangenwa lihlaselwa amakhemikhali eziphilayo nokuguguleka) | Phezulu (Umklamo oqondile wonga indawo ebalulekile yendawo yokuhlanza) |
Amabhanka/Imigodi Kakhonkolo Evulekile | Imbi (Iveza amakha amabi nezinto eziphilayo ngqo emvelweni) | Phansi (Idinga ukungenelela kwesilayidi esisebenza ngesandla) | Maphakathi (Ingase ibe nezinkinga zokuqhekeka kukakhonkolo ngenxa yokuhlaselwa yi-asidi) | Phansi (Idinga indawo enkulu evundlile) |
Izitsha Zokulahla Ezijwayelekile Ezigoqwayo | Phansi ukuya Maphakathi (Zivame ukuvuza nokukhipha umusi ngesikhathi zilayishwa) | Phansi | Phansi ukuya Maphakathi | Maphakathi |
Izicelo Ezibalulekile Zomasipala Nezimboni
Izikhungo Zokuhlanza Amanzi Angcolile Omasipala: Ukugcina ikhekhe lesludge lezinto eziphilayo elimisiwe elikhiqizwa amathangi okuhlala esibili nama-bioreactors ngaphambi kokuthi luthuthwe ngamaloli nsuku zonke.
Izikhungo Zokukhipha Amanzi Emfucumfucu Nokucubungula: Zisebenza njengezinqolobane zokulinganisa ukuphuma okushintshashintshayo kwezikhungo zokukhipha amanzi emfucumfucu nezinhlelo zokulahla umfucumfucu wesifunda.
Ukwelashwa Kwezindala Zezimboni: Kuqukethe umfucumfucu onzima wezinto eziphilayo noma zamakhemikhali okhiqizwa izimboni zokugaya amapulangwe, izimboni zokucubungula ukudla, nezimboni zokukhiqiza amakhemikhali.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Kungani izinqolobane zomfucumfucu wendle zidinga izinhlelo ezikhethekile zokukhipha umfucumfucu ngaphansi?
A: I-sludge yendle emisiwe (ikhekhe le-sludge) iyahlanganisa, iyancipha, futhi ivame ukuhlanganisa nokupakana ngaphansi kwesisindo sayo. Izitsha ezijwayelekile eziphakelwa ngamandla adonsela phansi zingabangela ukuthi i-sludge igobeke futhi ivale; ngakho-ke, izinqolobane zisebenzisa izakhiwo zokuhambisa ezinamandla okuphusha noma izinto ezikhipha ezijikelezayo ukuze kuphushwe izinto ngokomshini ngasemnyango wokukhipha.
Q: Iphathwa kanjani iphunga elibi esinqolobaneni se-sludge yendle?
A: I-sludge yendle ikhipha i-hydrogen sulfide nezinye izinto ezinuka kabi njengoba ihlala. Izinqolobane zivalwa ngokuphelele ngezembozo ezingangeni umoya futhi zifakwe ama-blower okungenisa umoya athwebula amagesi angaphezulu bese ewathumela ngezihlungi zebhayoloji, izihlungi zekhabhoni, noma izinhlelo zokwelapha ngamakhemikhali ngaphambi kokukhipha umoya ohlanzekile.
Q: Kungani amathangi e-Glass-Fused-to-Steel (GFS) ekhethwa ukuze kugcinwe i-sludge?
A: Amathangi e-GFS ahlanganisa amandla aphezulu esakhiwo sensimbi nokugqokwa kwangaphakathi nangaphandle okwenziwe ngengilazi engenzi lutho. Indawo ebushelelezi kakhulu yengilazi ivimbela udaka olunamathelayo ukuba lungabambeli ezindongeni, imelana nokugqwala kwamakhemikhali okuvela kuma-asidi ebhayoloji, futhi iqeda isidingo sokupenda kabusha ngaphandle ngezikhathi ezithile.
Q: Kwenzekani ngodaka ngemva kokuba lukhishwe esilweni?
A: Uma selukhishwe ngamasango avulekayo angezansi noma ngama-screw conveyor aqondiswe emalolini alindile, udaka luyathuthwa luyiswe ekulahleni okuphelele noma ekusetshenzisweni okuzuzisayo, okuvamise ukufaka ukusetshenziswa emasimini ezolimo, ukwenza umquba, ukubola ngaphandle komoya, noma ukushiswa ngomlilo.
