Lapha kumagazini i-Water, sihlala sifuna imisebenzi eye yanqoba izinselele ngezindlela ezingazuzisa abanye. Sigxile esilinganisweni sokugeleza endaweni encane yokuhlanza amanzi angcolile (WwTW) eCornwall, sikhulume nababambe iqhaza ababalulekile bephrojekthi…
Imisebenzi yokuhlanza amanzi angcolile amancane ivamise ukwethula izinselele ezibalulekile ezithinta izinsimbi nokulawula onjiniyela. Kodwa-ke, indawo yokulinganisa ukugeleza ethobelanayo ifakiwe embonini ese-Fowey, eningizimu-ntshonalanga ye-England, ngokubambisana okubandakanya inkampani yamanzi, usonkontileka, umhlinzeki wezinsimbi kanye nenkampani yokuhlola.
I-flow monitor kwa-Fowey WwTW yayidinga ukushintshwa njengengxenye yohlelo lokugcinwa kwezimali okuyinselele obeluyinselele ngenxa yesimo esibambekayo sesiza. Ngakho-ke, izixazululo ezintsha kakhulu zazibhekwa njengenye indlela yokushintsha okufana nokufana.
Onjiniyela bakwaTecker, usonkontileka we-MEICA waseNingizimu Ntshonalanga Yamanzi, ngakho-ke babuyekeze izinketho ezikhona. "Isiteshi siphakathi kwemisele emibili yokungenisa umoya, futhi ibingekho indawo eyanele yokwelula noma ukuguqula isiteshi," kuchaza u-Tecker Project Engineer Ben Finney.
okwasemuva
Izilinganiso ezinembile zokugeleza kwamanzi angcolile zenza abaphathi bezikhungo zokuhlanza basebenze kahle - ukulungisa ukwelashwa, ukunciphisa izindleko nokuvikela imvelo. Ngenxa yalokho, i-Environmental Agency ibeke izidingo eziqinile zokusebenza kumathuluzi okuqapha ukugeleza kanye nezakhiwo zezikhungo zokuhlanza indle e-England. Izinga lokusebenza licacisa izidingo ezincane zokuzigada ngokwakho ukuhamba.
Izinga le-MCERTS lisebenza kumasayithi anikezwe ilayisense ngaphansi kweMithetho Yezimvume Zemvelo (EPR), edinga abaqhubi bezinqubo ukuthi baqaphe ukugeleza koketshezi lwendle noma amanzi alahlwayo athengiswayo futhi baqoqe futhi babhale phansi imiphumela. I-MCERTS ibeka izimfuneko eziyisisekelo zokuzigada kokugeleza, futhi opharetha bafake amamitha ahlangabezana nezidingo zamalayisensi ze-Environmental Agency. Ilayisense Yezinsiza Zemvelo yase-Wales ingase futhi inikeze ukuthi isistimu yokuqapha ukugeleza iqinisekiswe yi-MCERTS.
Amasistimu nezakhiwo zokulinganisa ukugeleza okulawulwayo ngokuvamile kuhlolwa minyaka yonke, futhi ukungathobeli kungabangelwa izici eziningi, njengokuguga nokuguguleka kwamashaneli, noma ukwehluleka ukunikeza izinga elidingekayo lokunemba ngenxa yezinguquko ekuhambeni. Isibonelo, ukukhula kwenani labantu bendawo okuhambisana nokwenyuka kwezinga lemvula ngenxa yokushintsha kwesimo sezulu kungaholela “ekukhukhuleni” kwezakhiwo zokugeleza kwamanzi.
Ukuqapha ukugeleza kwesikhungo sokuhlanza indle i-Fowey
Ngokwesicelo sikaTecker, onjiniyela bavakashele le ndawo futhi eminyakeni yamuva nje ukuthandwa kobuchwepheshe kukhule kakhulu.” "Lokhu kuvame ukuthi kungenxa yokuthi ama-flowmeters angafakwa ngokushesha futhi kalula eziteshini ezilimele noma eziguga ngaphandle kwesidingo semisebenzi emikhulu yemali."
Ama-flowmeters axhumene alethwa kungakapheli inyanga e-odwe futhi afakwa esikhathini esingaphansi kwesonto. Ngokuphambene, umsebenzi wokukhanda noma wokushintsha osinki uzothatha isikhathi eside ukuze uhlelwe futhi usetshenziswe; kubiza imali eningi; ukusebenza okuvamile kwesikhungo kuzothinteka futhi ukuthobela kwe-MCERTS akunakuqinisekiswa.
Indlela eyingqayizivele ye-ultrasonic correlation engakwazi ukulinganisa ngokuqhubekayo ama-velocities emazingeni ahlukene ngaphakathi kwesigaba sokugeleza. Le nqubo yesifunda yokulinganisa ukugeleza ihlinzeka ngephrofayela yokugeleza kwe-3D ebalwe ngesikhathi sangempela ukuze kunikezwe ukufundwa kokugeleza okuphindaphindekayo nokuqinisekiswayo.
Indlela yokulinganisa isivinini isekelwe esimisweni sokubonakaliswa kwe-ultrasonic. Ukuboniswa emanzini angcolile, njengezinhlayiya, amaminerali noma amabhamuza omoya, kuskenwa kusetshenziswa ama-ultrasonic pulses ane-Engeli ethile. I-echo ewumphumela igcinwa njengesithombe, noma iphethini ye-echo, futhi ukuskena kwesibili kwenziwa ama-millisecond ambalwa kamuva. Iphethini ye-echo ewumphumela iyalondolozwa futhi ngokuhlobanisa/ngokuqhathanisa amasignali alondoloziwe, indawo yesibonisi esibonakala ngokucacile singabonakala. Ngenxa yokuthi izibonisi zihamba namanzi, zingabonakala ezindaweni ezihlukene esithombeni.
Ngokusebenzisa i-Angle ye-boam, isivinini sezinhlayiyana singabalwa futhi ngaleyo ndlela isivinini samanzi angcolile singabalwa kusukela ekuthuthweni kwesikhathi kwesibonisi. Ubuchwepheshe bukhiqiza ukufundwa okunembe kakhulu ngaphandle kwesidingo sokwenza izilinganiso zokulinganisa ezengeziwe.
Ubuchwepheshe buklanyelwe ukusebenza ngepayipi noma ipayipi, buvumela ukusebenza okuphumelelayo ezinhlelweni ezifunwa kakhulu nezingcolisayo. Izici zethonya ezifana nokuma kosinki, izici zokugeleza kanye nokuqina kodonga kubhekwa ekubalweni kokugeleza.
Okulandelayo yimikhiqizo yethu ye-hydrologic, wamukelekile ukubonisana
