Njengoba ukunakwa komhlaba wonke ekuvikelweni kwemithombo yamanzi nokuvikeleka kwamanzi kukhula, izinzwa zekhwalithi yamanzi seziphenduke isisekelo sokuqoqwa kwedatha, futhi izinhlelo zazo zokusebenza zigxiliswe ngokujulile kuzo zonke izimo ezihlukahlukene zokuqapha imvelo. Izibonelo zezifundo zamazwe ngamazwe ezilandelayo zibonisa ukuthi lezi zinzwa zidlala kanjani indima ebalulekile ezimweni ezahlukene.
Ikesi 1: I-United States - Inethiwekhi Yokuqapha Ikhwalithi Yamanzi Yesikhathi Sangempela Esigodini Somfula i-Delaware
Ingemuva:
I-Delaware River Basin inikeza amanzi okuphuza cishe kubantu abayizigidi ezingu-15 enyakatho-mpumalanga ye-United States, okwenza ukuphathwa kwekhwalithi yamanzi nokulawulwa kwezikhukhula kubaluleke kakhulu.
Isicelo nesixazululo:
Isiphathimandla sokuphatha umgodi sisungule inethiwekhi yokuqapha izinga lamanzi ngesikhathi sangempela ehlanganisa yonke indawo yamanzi. Izinzwa zekhwalithi yamanzi ezinamapharamitha amaningi zisatshalaliswa ezindaweni ezibalulekile emifuleni, ezindaweni zokulondoloza amanzi, nasezindaweni ezithathwayo, ezikalwa ngokuqhubekayo:
- Amapharamitha Angokwenyama: Izinga lokushisa lamanzi, i-turbidity, conductivity
- Amapharamitha Amakhemikhali: I-oxygen encibilikile, i-pH, ukuhlushwa kwe-nitrate
Lezi zinzwa zidlulisela idatha kusikhungo sokulawula esimaphakathi ngesikhathi sangempela ngesathelayithi noma amanethiwekhi eselula. Uma kutholwa okudidayo (isb., ukukhuphuka okubukhali kwe-turbidity kusuka esiphepho noma umcimbi ongaba khona ukungcola), isistimu icupha isexwayiso esisheshayo.
Imiphumela:
- Ivikela Amanzi Okuphuza: Izitshalo zokuhlanza amanzi zingaxwayiswa kusengaphambili ngezinguquko zekhwalithi yamanzi omthombo, ezivumela ukuthi zilungise izinqubo zokwelashwa ngokushesha.
- Isexwayiso Sesikhukhula Sengculazi Nokungcola: Ihlinzeka ngedatha yesikhathi sangempela yamamodeli ezikhukhula futhi inike amandla ukuhlonzwa okusheshayo kwemithombo yokungcola, ifinyeze izikhathi zokusabela eziphuthumayo.
- Isekela ucwaningo lwe-Ecosystem: Idatha yesikhathi eside, eqhubekayo inikeza ulwazi olubalulekile lokutadisha umthelela wokuguquka kwesimo sezulu kanye nemisebenzi yabantu endaweni ezungezile yamanzi.
Icala lesi-2: I-European Union - Ukuqapha Izinzwa Zomsoco kanye Nokuphathwa Kwezolimo e-Seine Estuary
Ingemuva:
E-Europe, ikakhulukazi emazweni angamalungu aboshwe yi-Water Framework Directive, ukulawula ukungcoliswa kwemithombo yezolimo (isb., imisoco ye-nitrogen ne-phosphorus) kuyinselele eyinhloko yokuthuthukisa ikhwalithi yamanzi. Ichweba laseSeine eFrance lingenye yendawo enjalo.
Isicelo nesixazululo:
Ama-ejensi wendawo wendawo akhiphe izinzwa ze-nitrate ezinemba okuphezulu endaweni yomfula kanye nemingenela yakhona eyinhloko. Lezi zinzwa azisetshenziselwa ukuqapha ngemuva kwe-post-facto kuphela kodwa zihlanganiswe nedatha yomsebenzi wezolimo ukuze kwakheke uhlelo lwempendulo yokuphathwa kwezolimo olunembayo.
- Izinzwa zihlale ziqapha ukugxila kwe-nitrate, zenza imephu ukuhlukahluka kwazo kwesikhashana nendawo.
- Imininingwane inikezwa imifelandawonye yezolimo yasendaweni kanye nabalimi, ikhombisa ngokusobala umthelela wangempela wezinqubo ezahlukene zokulima kanye nesikhathi sokufakwa kukamanyolo kwikhwalithi yamanzi angezansi komfula.
Imiphumela:
- Ithuthukisa Ukulima Okunembayo: Abalimi bangalungiselela isikhathi kanye nenani likamanyolo ngokusekelwe kudatha yokuqapha, behlise ukugeleza kwezakhi emthonjeni kuyilapho begcina isivuno futhi befeza izibopho zemvelo.
- Ihlola Ukusebenza Kwenqubomgomo: Le nethiwekhi yokuqapha ihlinzeka ngobufakazi obuningi bokuhlola izinzuzo zemvelo ze-EU's Common Agricultural Policy.
Ikesi 3: I-Singapore - Inzwa Ebanzi Ohlelweni Lwamanzi Asemadolobheni ngaphansi Kohlaka Lwesizwe Oluhlakaniphile
Ingemuva:
Njengemodeli ethi “Smart Nation,” i-Singapore inobuchwepheshe bezinzwa obuhlanganise ngokugcwele kuyo yonke iluphu yayo yonke yamanzi, okuhlanganisa ukukhiqizwa kwe-NEWater, ukusatshalaliswa kwamanzi aphuzwayo, nokuhlanza amanzi angcolile.
Isicelo nesixazululo:
- Amadamu Nemithombo Yamanzi: Izinzwa zekhwalithi yamanzi ezinamapharamitha amaningi kanye nama-biosensors (isb, ukusebenzisa izinhlanzi eziphilayo ukuqapha ubuthi) zisetshenziselwa ukuqapha okungaphazamiseki okungama-24/7 ukuze kuqinisekiswe ukuphepha kwamanzi emthonjeni.
- Inethiwekhi Yokusabalalisa Amanzi: Inethiwekhi enkulu yezinzwa isetshenziswa kuwo wonke amapayipi okuhambisa amanzi asemadolobheni, iqapha izinkomba ezibalulekile njenge-chlorine esele, i-pH, kanye ne-turbidity ngesikhathi sangempela. Uma kutholwa okudidayo noma i-chlorine esele inganele, isistimu ingalungisa ngokuzenzakalela imithamo ye-chlorination noma ithole ngokushesha izindawo ezingaba khona zokungcolisa, iqinisekise ukuphepha kwamanzi “kwimayela lokugcina.”
- Izimila Zokuhlanza Amanzi Angcolile: Izinzwa eziku-inthanethi ze-ammonia nitrogen, i-nitrate, ne-COD (Isidingo Se-Chemical Oxygen) zithuthukisa izinqubo zokwelashwa kokungena komoya nodaka, zithuthukisa kakhulu ukusebenza kahle nokunciphisa ukusetshenziswa kwamandla.
Imiphumela:
- Inika amandla Ukulawulwa Kweluphu Evaliwe: Ukuphathwa okuqhutshwa yidatha kusuka kokuthi "tap to tap" kuqinisekisa ukuphepha nokusebenza kahle kokuphakelwa kwamanzi okusezingeni eliphezulu.
- Ithuthukisa Ukusebenza Ngekhono Lokusebenza: Idatha yenzwa ishintsha ukusebenza kwezindawo zamanzi isuke kosuselwe kokuhlangenwe nakho iye ekuqageleni nasekuthuthukisweni, okonga izindleko zokusebenza.
Ikesi 4: Japan - Ukuqapha Kwenzwa Yesikhathi Eside Nocwaningo Lwe-Lake Ecosystems
Ingemuva:
I-Japan iyikhaya lamachibi amaningi abalulekile, njengeLake Biwa, impilo yalo ye-ecosystem ekhathaza kakhulu. Ukuvimbela i-eutrophication kanye ne-cyanobacterial blooms kuyinhloko yokuphatha.
Isicelo nesixazululo:
Izikhungo zocwaningo nezindikimba zokuphatha zisebenzisa amabhoya okuqapha aqondile emachibini. Lawa mabhoya afakwe izinzwa zekhwalithi yamanzi ezikala ekujuleni okuhlukene:
- I-Chlorophyll-i-concentration (ekhombisa ngokuqondile i-algal biomass)
- I-Phycocyanin (iqondene ngqo ne-algae eluhlaza okwesibhakabhaka)
- I-Oxygen Encibilikisiwe (isetshenziselwa ukunquma ukuhlukaniswa kwamanzi nezimo ze-anoxic)
- Amanzi Okushisa
Lawa mabhuya aqoqa idatha ngokuhamba kwesikhathi kumaza aphezulu, akha amamodeli aguquguqukayo we-ecosystem yechibi, ngokuvamile ahlanganiswe nokuzwa okukude kwesathelayithi.
Imiphumela:
- Ukubikezela Okunembile Kwe-Algal Bloom: Ukuqapha okuqhubekayo kwe-chlorophyll-a ne-phycocyanin kuvumela ukubikezelwa kokuqhakaza kwe-algal kusasele izinsuku ezimbalwa, kunikeze isikhathi esibalulekile sokuba abaphathi basebenzise izinyathelo zokuphikisa.
- Ijulisa Ukuqonda Kwemvelo: Idatha yesikhathi eside, enesinqumo esiphezulu inikeza isisekelo sesayensi esingenakuthathelwa indawo sokuqonda ukuthi i-ecosystem yechibi isabela kanjani ekushintsheni kwesimo sezulu.
Isiphetho
Kusukela ekuphathweni kwezindawo ezinkulu zamanzi e-US kuya ekulawuleni ukungcoliswa kwezolimo e-EU, futhi kusukela ezinhlelweni zamanzi ahlakaniphile zasemadolobheni e-Singapore kuya ocwaningweni lwe-ecosystem yechibi e-Japan, lezi zimo zamazwe ngamazwe zibonisa ngokucacile ukuthi izinzwa zekhwalithi yamanzi ziye zavela ngaphezu kwamathuluzi alula wokuqoqa idatha. Manje sebeyimpahla eyinhloko yokufeza ukuphathwa kwemvelo okunembayo, ukuqinisekisa ukuphepha komphakathi, ukuthuthukiswa kocwaningo lwesayensi, nokuthuthukisa ukusebenza kahle kwengqalasizinda. Njengoba ubuchwepheshe be-IoT ne-AI buqhubeka buthuthuka, ukusetshenziswa komhlaba wonke kwezinzwa zekhwalithi yamanzi ngokungangabazeki kuzojula futhi kuhlakaniphe nakakhulu.
Futhi singahlinzeka ngezixazululo ezahlukahlukene
1. Imitha ephathwa ngesandla yekhwalithi yamanzi enepharamitha eningi
2. Isistimu ye-Buoy entantayo yekhwalithi yamanzi enepharamitha eminingi
3. Ibhulashi lokuhlanza okuzenzakalelayo lenzwa yamanzi yepharamitha eminingi
4. Isethi ephelele yamaseva nesoftware engenantambo, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
