Ngokukhula kokuntuleka kwamanzi nokukhathazeka okukhulayo ngokungcoliswa kwamanzi, ubuchwepheshe bokuqapha izinga lamanzi buye baba ithuluzi eliwumgogodla ekuvikelweni kwemvelo. Phakathi kwalobu buchwepheshe, inzwa ye-nitrite—umshini wokubona onembile kakhulu, wesikhathi sangempela—idlala indima ebalulekile emikhakheni eminingi. I-Nitrite (NO₂⁻) iwukungcola okuvamile ezindaweni ezinamanzi, ngokuyinhloko kusukela emanzini angcolile ezimbonini, ukugeleza kwezolimo, kanye nendle yasekhaya. Amazinga adlulele angaholela ku-eutrophication futhi aze afake izinsongo empilweni yabantu. Lesi sihloko sihlola izimo zohlelo lokusebenza nomthelela ongokoqobo wale nzwa ngokujulile.
1. Ukuhlanza Amanzi Angcolile Kamasipala: Ukuthuthukisa Ukusebenza Kahle kanye Nokuqinisekisa Ukuthobelana
Ezitshalweni zikamasipala zokuhlanza amanzi angcolile, izinzwa ze-nitrite zisetshenziswa kakhulu ukuqapha inqubo. Ngokulinganisa ukugxiliswa kwe-nitrite emathangeni omoya kanye namayunithi okusabela kwe-anaerobic/aerobic ngesikhathi sangempela, opharetha bangakwazi ukulawula ngokunembile amazinga okungena umoya kanye nomthamo womthombo wekhabhoni ukuze bathuthukise inqubo yokukhishwa kwe-denitrification. Isibonelo, ezinqubweni ze-nitrification-denitrification, i-nitrite buildup ingavimbela umsebenzi we-microbial, futhi izinzwa zinikeza izexwayiso zangaphambi kwesikhathi ukuvimbela ukwehluleka kwesistimu.
Imiphumela:
- Ithuthukisa kakhulu ukusebenza kahle kwe-denitrification, yehlisa ukusetshenziswa kwamandla kanye nokusetshenziswa kwamakhemikhali.
- Iqinisekisa ukuthi amazinga e-nitrite angcolile athobelana namazinga kazwelonke okukhipha (isb., GB 18918-2002).
- Yehlisa izindleko ezihambisana namasampula okwenziwa mathupha nokuhlaziywa kwelebhu, okuvumela ukusebenza okuhlakaniphile nokunakekelwa.
2. I-Aquaculture: Ukuvimbela Izifo kanye Nokuqinisekisa Ukuphepha
Emachibini e-aquaculture, i-nitrite ingumkhiqizo ophakathi ekuguquleni i-ammonia nitrogen. Ukugxila okuphezulu kungabangela izinhlanzi ukuthi zihlupheke ngenxa yokuntuleka komoya-mpilo, ukuncipha komzimba, ngisho nokufa kwabantu abaningi. Izinzwa ze-Nitrite zingahlanganiswa ezinhlelweni zokuqapha izinga lamanzi ezisekelwe ku-IoT ukuze zilandelele ngokuqhubekayo izimo zamanzi futhi zithumele izexwayiso ngamadivayisi eselula.
Imiphumela:
- Inikeza izexwayiso zesikhathi sangempela zamaleveli e-nitrite eqile, okuvumela abalimi ukuthi bathathe izinyathelo ezifika ngesikhathi njengokushintsha kwamanzi noma ukufaka umoya.
- Yehlisa ubungozi bezifo zezinhlanzi, ithuthukise amazinga okusinda kanye nesivuno.
- Ikhuthaza ukunemba kwezolimo zasemanzini, ukunciphisa ukusetshenziswa kabi kwezidakamizwa kanye nokuqinisekisa ukuphepha komkhiqizo wasemanzini.
3. Ukuqapha Umthombo Wamanzi Okuphuza: Ukuvikela Imithombo kanye Nezempilo Yomphakathi
Ukuqapha amazinga e-nitrite emithonjeni yamanzi okuphuza (isb., amachibi, imifula) kuwumugqa obalulekile wokuvikela ukuphepha kwezempilo yomphakathi. Izinzwa zingahlanganiswa eziteshini zokuqapha ezizenzakalelayo ukwenza ukugada okungu-24/7 kwemithombo yamanzi. Uma ukugxila okungavamile kutholwa (isb, ngenxa yokungcoliswa kwezolimo noma izingozi zezimboni), uhlelo luqala ngokushesha impendulo ephuthumayo.
Imiphumela:
- Ivumela ukutholwa kusenesikhathi kwemicimbi yokungcola, ivimbele amanzi angcolile ukuthi angangeni kunethiwekhi yokuhlinzeka.
- Isekela iziphathimandla zamanzi ekwenzeni izinqumo ezisheshayo kanye nokuqala izinyathelo zokuhlanza.
- Ithobelana “Nezimiso Zekhwalithi Yamanzi Okuphuza” (GB 5749-2022), okuthuthukisa ukwethenjwa komphakathi.
4. Ukuqapha Amanzi Angcolile Embonini: Ukulawulwa Okunembayo Kokungcoliswa Kwemvelo kanye Nokukhiqiza Okuluhlaza
Amanzi angcolile avela ezimbonini ezifana ne-electroplating, ukuphrinta, ukudaya, nokucubungula ukudla ngokuvamile aqukethe amazinga aphezulu e-nitrite. Izinzwa zingasetshenziselwa ukuqapha ngesikhathi sangempela ezindaweni zokulahla amanzi ebhizinisi noma ezindaweni zokuhlanza amanzi angcolile epaki yezimboni, ngedatha exhunywe ezinkundleni zezinhlangano zokuvikela imvelo.
Imiphumela:
- Isiza amabhizinisi ukuthi afinyelele ekuphathweni okucolisisiwe kwezinqubo zokuhlanza amanzi angcolile, agweme ukukhishwa okungathobeli imithetho.
- Isekela ukuphoqelelwa komthetho wezemvelo ngokunikeza ubufakazi bedatha obungenaphutha ngokumelene nokukhishwa okungekho emthethweni.
- Ikhuthaza ukongiwa kwamandla kanye nokunciphisa ukungcola, okunikela emigomeni yokungathathi hlangothi kwekhabhoni.
5. Ucwaningo Lwesayensi kanye Nokuqapha Kwemvelo: Ukwembula Amaphethini kanye Nokuvikela Imvelo
Ezindaweni ezizwelayo ngokwemvelo njengamachibi nezizalo zemifula, abacwaningi basebenzisa izinzwa ze-nitrite ukuze balandelele izinqubo zamabhayisikili e-nitrogen futhi bahlaziye izimbangela ze-eutrophication. Idatha yokuqapha yesikhathi eside iphinde isize ukuhlola ukusebenza kahle kwamaphrojekthi emvelo afana nokubuyiselwa kwamaxhaphozi kanye nokutshalwa kabusha kwamahlathi.
Imiphumela:
- Ijulisa ukuqonda kwesayensi kwezindlela zokugibela i-nitrogen emanzini.
- Ihlinzeka ngosekelo lwedatha lokuphathwa kwemvelo, ithuthukisa amasu okuvikela imvelo.
- Ithuthukisa amandla okubikezela mayelana nokushintsha kwezinga lamanzi kumongo wokuguquka kwesimo sezulu.
Isiphetho: Ubuchwepheshe Ukunika Amandla Ikusasa Lokulawulwa Kwemvelo Yamanzi
Ngezinzuzo ezinjengokuzwela okuphezulu, ukuphendula okusheshayo, kanye ne-automation, izinzwa ze-nitrite ziba ithuluzi elibalulekile ekulawuleni imvelo yamanzi. Kusukela emadolobheni kuya ezindaweni zasemaphandleni, kusukela ekukhiqizeni kuya ekuphileni kwansuku zonke, baqapha buthule ukuphepha kwawo wonke amaconsi amanzi. Njengoba ubuchwepheshe bezinzwa buqhubeka buhlanganisa nobuhlakani bokwenziwa kanye nedatha enkulu, ikusasa lithembisa ngisho namanethiwekhi okuxwayisa ngekhwalithi yamanzi ahlakaniphe kakhulu nasebenza kahle, okuqhubeza umfutho wezobuchwepheshe wentuthuko esimeme.
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
