Izinzwa ze-Water EC (izinzwa ze-electric conductivity) zidlala indima ebalulekile ekukhuliseni izinhlanzi ngokulinganisa i-electric conductivity (EC) yamanzi, okubonisa ngokungaqondile ukuhlushwa okuphelele kosawoti, amaminerali, nama-ion ancibilikisiwe. Nazi izinhlelo zokusebenza nemisebenzi yazo ethile:
1. Imisebenzi Eyinhloko
- Ukuqapha Usawoti Wamanzi:
Amanani e-EC ahlobene kakhulu nosawoti wamanzi, okusiza ekunqumeni ukuthi amanzi afanele yini izinhlobo ezithile zasemanzini (isb., izinhlanzi zasemanzini ahlanzekile, izinhlanzi zasolwandle, noma izimfanzi/izinkalankala). Izinhlobo ezahlukene zinezinga elihlukahlukene lokubekezelela usawoti, futhi izinzwa ze-EC zinikeza izexwayiso zesikhathi sangempela zamazinga angajwayelekile osawoti. - Ukuhlola Ukuqina Kwamanzi:
Izinguquko ku-EC zingase zibonise ukungcola, ukuncibilika kwamanzi emvula, noma ukungena kwamanzi angaphansi komhlaba, okuvumela abalimi ukuthi bathathe izinyathelo zokulungisa ngesikhathi.
2. Izicelo Ezithile
(1) Ukuthuthukisa Indawo Yokulima
- Ukufuywa Kwezinhlanzi Zasemanzini Ahlanzekile:
Kuvimbela ukucindezeleka ezimpilweni zasemanzini ngenxa yokwanda kosawoti (isb., ngenxa yokwakheka kwemfucuza noma izinsalela zokudla). Isibonelo, i-tilapia ikhula kahle ebangeni le-EC elingu-500–1500 μS/cm; ukuphambuka kungaphazamisa ukukhula. - Ukufuywa Kwezinhlanzi Zasolwandle:
Iqapha ukuguquguquka kosawoti (isb., ngemva kwemvula enkulu) ukuze igcine izimo ezizinzile zezinhlobo ezibucayi njengezinhlanzi kanye nezinhlanzi.
(2) Ukuphathwa Kokudla Nemithi
- Ukulungiswa Kokuphakelayo:
Ukwanda okungazelelwe kwe-EC kungabonisa ukudla okuningi okungadliwanga, okubangela ukuncipha kokudla ukuze kuvinjelwe ukwehla kwekhwalithi yamanzi. - Ukulawulwa Kwesilinganiso Semithi:
Ezinye izindlela zokwelapha (isb., amabhati kasawoti) zincike emazingeni kasawoti, kanti izinzwa ze-EC ziqinisekisa ukuqapha okunembile kokuhlushwa kwama-ion.
(3) Imisebenzi Yokuzalanisa Nokuqandusela Izinyoni
- Ukulawulwa Kwendawo Yokufukama:
Amaqanda ezinhlanzi kanye nezibungu zizwela kakhulu ekubunjweni kosawoti, futhi amazinga e-EC azinzile athuthukisa amazinga okuchamisela (isb., amaqanda e-salmon adinga izimo ezithile ze-EC).
(4) Ukuphathwa Kwemithombo Yamanzi
- Ukuqapha Amanzi Okungenayo:
Ihlola i-EC yemithombo yamanzi emisha (isb., amanzi angaphansi komhlaba noma imifula) ukuze igweme ukufaka amanzi anosawoti omningi noma angcolile.
3. Izinzuzo kanye Nesidingo
- Ukuqapha Kwangempela:
Ukulandelela okuqhubekayo kwe-EC kusebenza kahle kakhulu kunokuthatha amasampula ngesandla, kuvimbela ukubambezeleka okungaholela ekulahlekelweni. - Ukuvimbela Izifo:
Amazinga kasawoti/ama-ion angalingani angabangela ukucindezeleka kwe-osmotic ezinhlanzini; izinzwa ze-EC zinikeza izixwayiso kusenesikhathi. - Ukusebenza Kahle Kwamandla Nezinsizakusebenza:
Uma zihlanganiswa nezinhlelo ezizenzakalelayo (isib. ukushintshaniswa kwamanzi noma ukungenisa umoya), ziyasiza ekunciphiseni imfucuza.
4. Izinto Ezibalulekile Okufanele Uzicabangele
- Isinxephezelo Sokushisa:
Ukufundwa kwe-EC kuncike ekushiseni, ngakho-ke izinzwa ezinokulungiswa kokushisa okuzenzakalelayo zibalulekile. - Ukulinganisa Okuvamile:
Ukungcola kwama-electrode noma ukuguga kungaphazamisa idatha; ukulinganisa ngezixazululo ezijwayelekile kuyadingeka. - Ukuhlaziywa Kwamapharamitha Amaningi:
Idatha ye-EC kufanele ihlanganiswe nezinye izinzwa (isb., i-oxygen encibilikisiwe, i-pH, i-ammonia) ukuze kuhlolwe ikhwalithi yamanzi ephelele.
5. Ububanzi obujwayelekile be-EC bezinhlobo ezivamile
| Izinhlobo Zokufuya Izinhlanzi | Ibanga Elifanele Le-EC (μS/cm) |
|---|---|
| Inhlanzi Yamanzi Ahlanzekile (i-Carp) | 200–800 |
| I-Pacific White Shrimp | 20,000–45,000 (amanzi olwandle) |
| I-Prawn Enkulu Yamanzi Ahlanzekile | 500–2,000 (amanzi ahlanzekile) |
Ngokusebenzisa izinzwa ze-EC ukuze kuqashwe ngokunembile, abalimi bezinhlanzi bangathuthukisa kakhulu ukuphathwa kwekhwalithi yamanzi, banciphise izingozi, futhi bathuthukise umkhiqizo kanye nenzuzo.
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
