Amathangi Okugcina Ezitshalweni Zamanzi Angcolile: Ukukhetha Imikhumbi Yesigaba Ngasinye Sokwelashwa
Izitshalo zamanzi angcolile ngokuyisisekelo ziyiqoqo lamathangi ahlelwe ngokulandelana, futhi isigaba ngasinye sifuna okuthile okuhlukile emkhunjini waso: amanzi angcolile angahluziwe adinga ukumelana nokugqwala, ukulinganisa kudinga ukuguquguquka kwevolumu, ama-digester adinga ukuvaleka kwegesi. Ukuwaphatha njengokuthenga 'kwethangi' elilodwa elijwayelekile yindlela izitshalo ezigcina ngayo zihluleka ngaphambi kwesikhathi.
Amathangi okugcina amanzi angcolile ezitshalweni zokuhlanza amanzi ayimikhumbi yokucubungula — ukulinganisa, ukufaka umoya, ukucacisa, ukugaya kanye namayunithi okugcina udaka — ngalinye likhethwa ngokuya nge-chemistry yemidiya yalo, isikhathi sokugcina kanye nemithwalo yesakhiwo, namathangi ensimbi ahlanganiswe nengilazi namathangi ensimbi ehlanganiswe ngento evikelayo asukela ku-20 kuya ku-60,000 m3.
Yimaphi Amathangi Okudinga Ukuwathola Isitshalo Esijwayelekile Sokuhlanza Amanzi Angcolile?
Amathangi okulinganisa: agcina ukushintshashintsha kwamanzi nokugcwala ngaphambi kokwelashwa kwezinto eziphilayo; ubukhulu bawo bulandela ijika lesikhathi sokugeleza, futhi izinto zokugcina ezingagqwali zilawula ukuhlasela kwe-sulfide yamanzi angcolile.
Izitsha zokucubungula: amachibi okufaka umoya, izindawo ezingena-umoya kanye nezitsha zokugaya ngakunye kufaka imithwalo yokuxuba, yama-diffuser kanye nokushisa emzimbeni — okwenza izinhlaka eziqinisiwe, ophahla abaqinile kanye nezembozo ezingangeni umoya.
Izihlanzi nezijiyisi: izitsha ezilawulwa ubujamo bezinto lapho ukwakhiwa kwensimbi eyindilinga kunikeza ukulawula kokulinganisa nokumisa okusheshayo uma kuqhathaniswa nokhonkolo ophonswayo endaweni.
Ukugcinwa kwe-sludge nokubuyisela uketshezi: umsebenzi wezinto eziqinile eziningi, onephunga elinamandla odinga izembozo ezivaliwe, ukuxuba nokufaka imibala okukalwe ku-pH 1-14 ukuze kusingathwe imithwalo ye-ammonia esemaceleni.
Ingabe I-Chemistry Yemidiya Namakhodi Kushayela Kanjani Ukukhethwa Kwezinto?
Ukumephu kokugqwala: izindawo ezingaphansi kwamanzi zibona ama-asidi e-organic, isikhala segesi sibona i-H2S condensate — kuphela imibala ehlanganiswe ngefektri efana ne-GFS noma i-FBE evikela zombili izindawo ngokufanayo amashumi eminyaka.
Uhlaka lwekhodi: i-AWWA D103 ne-EN 1090 zilawula ukwakheka kwamathangi ensimbi aboshwe ngamabhawodi, kanti i-NSF/ANSI 61 iyasebenza lapho kugcinwa khona amanzi asetshenziswa kabusha ezingeni lokuhlanzeka.
Ukuzamazama komhlaba nomoya: izimo zomthwalo eziqondene nendawo zivame ukunquma ubukhulu bethangi — izinhlelo zamaphaneli aboshwe ngamabhawodi zivumela ukulungiswa kobubanzi/ubude ngaphakathi komndeni owodwa womklamo oqinisekisiwe.
Kungani Imikhumbi Yensimbi Eboshiwe Ithatha Indawo Kakhonkolo Ekwandisweni Kwezimboni?
Ukuqiniseka ngeshejuli: amaphaneli akhiwe efemini aboshwa ngamabhawodi emasontweni ambalwa, ngaphandle kokuthembela ekuthululweni kukakhonkolo okulawulwa isimo sezulu, okuvumela izimboni ukuthi zihlangabezane nezikhathi zokuthobela imithetho.
Ezomnotho zempilo yonke: amathangi e-GFS ahlanganisiwe anikeza izimpilo zokumboza ezingaphezu kweminyaka engu-30 ngaphandle kwezinhlelo zokuphinda ambozwe, futhi angahlakazwa, athuthelwe kwenye indawo noma anwetshwe iringi ngiringi njengoba umthwalo ukhula.
Ukuqinisekiswa okubhaliwe: ukuhlolwa kweholide ezimbonini nge-1500V DC kukhiqiza amaphepha okwamukela imiphumela okulwa nokufinyelela kuwo ukumboza okusetshenziswa endaweni, okwenza lula ukuhlolwa kokunikezwa kwamandla.
I-Matrix yokuqhathanisa: Isigaba Sesitshalo vs Umkhumbi Onconyiwe
Isigaba Sesitshalo | Umsebenzi | Umkhumbi Onconyiwe | Ubude Besikhathi Esijwayelekile |
Ukulinganisa | Ukulawula ukugeleza/umthwalo | Insimbi eboshiwe ye-GFS noma i-FBE | Iminyaka engu-30+ |
Ichibi lokungenisa umoya | Ukwelashwa kwezinto eziphilayo | Insimbi eboshiwe enemibala / ukhonkolo | Iminyaka engu-20-30 |

Klamula ithangi ngalinye ngesigaba salo, hhayi ngesilinganiso sesitshalo. Izitshalo zamanzi angcolile zanamuhla ezithembekile zisebenzisa imindeni yensimbi eboshelwe efakwe ifektri ekuqinisekiseni ukulingana, ukugaya kanye nomsebenzi wendle — kuthola izingxenye ezabiwe, amaqembu okwakha avamile kanye nesikhathi sokumboza seminyaka engu-30 okugcina izindleko zobunikazi ziqikeleka.
Imibuzo Ejwayelekile (FAQ)
Q1: Iyiphi ithangi elingagqwali kakhulu ezitshalweni zamanzi angcolile?
Amathangi ensimbi ahlanganiswe nengilazi (glass-fused-to-steel bolted tanks), lapho ungqimba lwawo lwe-enamel luhlanganiswa khona ngezinga lokushisa elingu-820-930°C lube isithiyo esingasebenzi nge-pH 1-14, amelana nokuhlaselwa yi-asidi ephilayo engaphansi kwamanzi kanye ne-H2S condensate endaweni yegesi — lezi yizindawo ezimbili zokugqwala ezidala ukwehluleka kwezikhungo zokuhlanza amanzi angcolile.
Umbuzo 2: Zingaki amathangi umkhungo wokuhlanza amanzi angcolile wodolobha ovamise ukuba nawo?
Umkhungo omaphakathi uvamise ukusebenzisa imikhumbi ehlukene engu-8-15: amayunithi okuhlola nokulinganisa, amabhesini okungenisa umoya, ama-clarifier esibili, i-digester eyodwa noma ngaphezulu, kanye nokubamba udaka namathangi amakhemikhali — ngamunye unezinto ezikhethekile zokusebenza nokumboza.
Umbuzo 3: Ingabe amathangi ensimbi ahlanganisiwe angakwazi ukunwetshwa lapho umkhungo ukhula?
Yebo. Ukwakhiwa kwamaphaneli ahlanganisiwe kuvumela ukwenyuka komthamo ngokungeza amarings noma ukuphinda amathangi ezisekelweni ezilungisiwe, lokhu kuvumelana okungenakufinyelelwa ngamabhesini kakhonkolo ngokwezomnotho ngemva kokwakhiwa kokuqala.
Umbuzo 4: Ingabe amathangi okuhlanza amanzi angcolile adinga izembozo?
Izidingo zokumboza zilandela umsebenzi: ama-digester adinga izembozo ezingangeni umoya ukuze kutholakale i-methane, amathangi e-sludge nawokulinganisa ngokuvamile adinga izembozo ezivala iphunga ngokuhlanza umoya, kanti amachibi okucubungula angadinga izembozo zokugcina ukushisa noma ukulawula ulwelwe.
