Kwezolimo zanamuhla, ukuphathwa okunembile kanye nentuthuko esimeme sekuyizinto eziza kuqala kososayensi bezolimo. Ukuqapha ikhwalithi yamanzi kuyisici esibalulekile sale nqubo, ikakhulukazi mayelana ne-soluble carbon dioxide (CO₂). E-United States, izinzwa zekhwalithi yamanzi ze-CO₂ zisetshenziswa kabanzi emikhakheni efana nokutshalwa kwezitshalo eziluhlaza, ukufuywa kwezinhlanzi, kanye nezinhlelo zokunisela. Ngezansi kunesimo esithile esibonisa ukusetshenziswa okusebenzayo kwezinzwa zekhwalithi yamanzi ze-CO₂ kwezolimo zaseMelika.
Ingemuva
Indlu enkulu yokugcina izitshalo eseCalifornia igxile ekutshaleni imifino nezimbali ezibiza kakhulu futhi ibhekane nezinselelo mayelana nokuphathwa kwekhwalithi yamanzi kanye nokukhula kwezitshalo. Ngokuthuthuka kobuchwepheshe bezolimo, le ndlu yokugcina izitshalo isebenzise izinzwa zekhwalithi yamanzi ze-CO₂ ukuze kuthuthukiswe izimo zokukhula kwezitshalo futhi kuthuthukiswe kokubili isivuno kanye nekhwalithi.
Izicelo Eziwusizo
Ukuqapha Ikhwalithi Yamanzi
Indlu eluhlaza isebenzisa izinzwa ze-CO₂ zekhwalithi yamanzi ukuze iqaphe njalo ukugcwala kwe-carbon dioxide emanzini okunisela ngesikhathi sokunisela nokufaka umquba. Ngokulandelela amazinga e-CO₂ emanzini, ipulazi lingaqonda kangcono izinguquko ku-asidi yamanzi (pH) kanye nemiphumela yazo ekukhuleni kwezitshalo.
Uhlelo Lokunisela Oluhlakaniphile
Uma izinzwa zibona ukwenyuka kokuhlushwa kwe-CO₂ emanzini, uhlelo lulungisa ngokuzenzakalelayo ishejuli yokunisela. Lokhu kulungiswa okuzenzakalelayo kuthuthukisa ukuhlinzekwa kwamanzi nezakhamzimba, kuqinisekisa ukuthi izitshalo zikhula ngaphansi kwezimo ezifanele. Isibonelo, lapho ukuhlushwa kwe-CO₂ kuphansi, uhlelo lwandisa amazinga e-CO₂ ukukhuthaza i-photosynthesis, ngaleyo ndlela kuthuthukiswe amazinga okukhula kwezitshalo.
Ukubikezela Isivuno Sezitshalo
Ngokuhlaziya idatha yomlando kanye nedatha yekhwalithi yamanzi yesikhathi sangempela, abaphathi bezindawo zokugcina izithombo bangabikezela izitayela zokukhula kanye nesivuno esingaba khona sezitshalo zabo. Imininingwane enikezwa yizinzwa ze-CO₂ zekhwalithi yamanzi isekela ukwakheka kwezinqumo zokuphathwa kwezolimo ezinembile, njengokuhlela okufika ngesikhathi nokufanelekile kokufaka umanyolo kanye nokunisela.
Imiphumela kanye nempendulo
Ngemva kokusebenzisa ukuqapha ikhwalithi yamanzi ye-CO₂, indlu yokugcina izitshalo yathola ukwanda okukhulu kokukhiqiza. Ngonyaka wokuqala wokwethula izinzwa, isivuno sanda cishe ngo-20%, kanti nekhwalithi yezitshalo nayo yathuthuka kakhulu. Abaphathi babike ukuthi ukuqapha kanye nokulungiswa kwezimo zokunisela ngesikhathi sangempela kwabavumela ukuthi baphendule ngokushesha ezinkingeni zokukhula, banciphise imfucuza futhi bathuthukise ukusebenza kahle kwemithombo yamanzi.
Amathemba Esikhathi Esizayo
Njengoba ubuchwepheshe bezolimo buqhubeka nokuthuthuka, ukusetshenziswa kwezinzwa ze-CO₂ zekhwalithi yamanzi kuzokhula kuye ezindaweni eziningi zezolimo, okuhlanganisa ukufuywa kwezinhlanzi, ukuqapha inhlabathi, kanye nezinye izindawo zokutshala izitshalo. Ngokuhlanganisa ubuhlakani bokwenziwa kanye nokuhlaziywa kwedatha enkulu, ikusasa lezolimo lithembisa ukusebenza kahle kakhulu nokusimeme, okwenza kube lula ukuguquka ekukhiqizweni kwezolimo.
Isiphetho
Ngokusebenzisa izinzwa zekhwalithi yamanzi ze-CO₂ endaweni yokushisa yaseCalifornia, sibona indlela ezolimo zanamuhla ezisebenzisa ngayo ubuchwepheshe ukuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yezitshalo. Lokhu akugcini nje ngokuletha izinzuzo ezingokoqobo zokukhiqiza kwezolimo kodwa futhi kunikeza ukuqonda okubalulekile kokukhuthaza intuthuko yezolimo esimeme. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukuqapha ikhwalithi yamanzi kulungele ukuba yithuluzi elibalulekile ekuphathweni kwezolimo kwesikhathi esizayo.
Singaphinde sinikeze izixazululo ezahlukahlukene ze
1. Imitha ephathwayo yekhwalithi yamanzi enamapharamitha amaningi
2. Uhlelo lwe-Floating Buoy lwekhwalithi yamanzi enamapharamitha amaningi
3. Ibhulashi lokuhlanza elizenzakalelayo lenzwa yamanzi enamapharamitha amaningi
4. Isethi ephelele yamaseva kanye nemodyuli engenantambo yesofthiwe, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
Ukuze uthole inzwa yamanzi eyengeziwe ulwazi,
