Izinzwa ze-Optical Dissolved Optical Zivela Njengethuluzi Eliyinhloko Lokufuya Izinhlanzi Nokuphathwa Kwemvelo​

——Izifundo Zezimo Ezivela eVietnam, eNdiya, eBrazil, naseSaudi Arabia Zembula Imikhuba Yemboni​

​​20 Septhemba 2024​​ — Njengoba ukunaka komhlaba wonke ekuphathweni kwemithombo yamanzi kanye nokuvikelwa kwemvelo kukhula, izinzwa ze-optical dissolved oxygen (DO) sezibe ubuchwepheshe obuyinhloko ekuqapheni ikhwalithi yamanzi. Ngokusho kwedatha yakamuva evela ku-Alibaba International, ukuthengwa kwezinzwa ze-optical DO kukhuphuke ngo-75% unyaka nonyaka kwikota yesithathu, kanti iVietnam, iNdiya, iBrazil, kanye neSaudi Arabia zihamba phambili ekudingeni. Lo mbiko uhlola izinhlelo zokusebenza zangempela kula mazwe futhi uqokomisa izitayela zemboni ezisafufusa.

IVietnam: Ukuguqulwa Okuhlakaniphile Kwezolimo Zasemanzini

E-Mekong Delta yaseVietnam, iqembu elikhulu labalimi bezinhlanzi lisanda kuthenga izinzwa ze-optical DO ezingu-50 nge-Alibaba International ukuze ziqaphe ikhwalithi yamanzi echibini ngesikhathi sangempela. Lezi zinzwa ezingangeni manzi ze-IP68 ezinomphumela we-RS485 zixhuma epulatifomu yamafu, ziqala ngokuzenzakalelayo izivuseleli lapho amazinga e-DO ehla ngaphansi kuka-4mg/L.

Imiphumela: Amazinga okusinda kwezinhlanzi akhuphuke kusuka ku-60% kuya ku-85%, okwandisa imali engenayo yonyaka ngamaRandi ayizigidi ezingu-1.2. Imithethonqubo yaseVietnam ka-2024 iyalela ukuqapha kwe-DO ngesikhathi sangempela emapulazini amakhulu, okudala isidingo esikhulu.

Amagama angukhiye aphezulu okusesha:

• “Inzwa ye-DO yepulazi le-shrimp yaseVietnam”
• "I-optical dissolved oxygen probe amanzi anosawoti"

I-India: Ubuchwepheshe Bunika Amandla Ekuhlanzweni Komfula iGanges

Njengengxenye yesinyathelo saseNdiya esithi “Clean Ganga”, iBhodi Yokulawula Ukungcola yase-Uttar Pradesh ithumele ama-buoy okuqapha amapharamitha angu-200 anamamojula e-optical DO kanye nokudluliselwa kwe-GPRS eceleni komfula oyinhloko. Idatha idluliselwa kumadeshibhodi kahulumeni, inciphisa izikhathi zokusabela ekungcoleni.

Imiphumela: Impendulo yezehlakalo isheshiswe ngo-70%, okusiza ekubuyiselweni kwemvelo. I-India ihlela ukwandisa ukumbozwa kulo lonke isigodi saseGanges zingakapheli iminyaka emithathu.

Amagama angukhiye aphezulu okusesha:

• "I-buoy yokuqapha umfula i-India Ganges"
• "Inzwa ye-Optical DO yokwelapha indle"

IBrazil: Ukuqapha Ngokunembile Kwezindawo Zokudoba Ezishisayo

E-Amazon Basin, umswakama ophezulu kanye nemvula enkulu kuphonsela inselelo izinzwa zendabuko. Inhlangano yokudoba yaseManaus yamukele amamitha e-optical DO asebenza ngamandla elanga anemiklamo yokulwa nokugqwala, ithumela izexwayiso ezisebenzisa umoya-mpilo ophansi nge-SMS.

Imiphumela: Izindleko zokudla zehle ngo-18%, kanti amazinga ezifo zezinhlanzi ehle ngo-40%. I-Association of Aquaculture yaseBrazil ibikezela ukungena kwemakethe okungu-50% kwezinzwa zokukhanya zingakapheli iminyaka emihlanu.

Amagama angukhiye aphezulu okusesha:

• "I-monitor ye-DO yokufuya izinhlanzi eBrazil"
• “Inzwa ye-oksijini ebonakalayo engangeni manzi”

I-Saudi Arabia: Ukulawulwa Okunembile Kwezitshalo Zokukhipha Usawoti

I-Jubail Desalination Plant isebenzisa izinzwa ze-titanium optical DO (ezilinganiswe ngokucindezela okungu-20bar) ukulandelela umthelela wezinsalela ze-ozone emazingeni e-oxygen. Zihlanganiswe nezinhlelo ze-SCADA, zivumela ukuzenzekela okugcwele.

Imiphumela: Izindleko zokulungisa zehle ngo-65%, kanti imvamisa yokulinganisa yehle kusukela masonto onke kuya kowamakota. I-Saudi Arabia ihlose ukuhlomisa zonke izitshalo ezinkulu ngezinzwa zokukhanya ngo-2030.

Amagama angukhiye aphezulu okusesha:

• "Inzwa yesitshalo sokukhipha usawoti eMpumalanga Ephakathi"
• "I-OEM yokuhlola i-DO yokucindezela okuphezulu"

Izitayela Zemboni Nokuqonda Kwabahlinzeki

1. Intuthuko Yobuchwepheshe: Izembozo ezingenantambo (LoRa/NB-IoT) kanye ne-anti-biofouling sezijwayelekile manje, kanti ukusesha kwakamuva kukhuphuke ngo-120% ngonyaka.
2. Izitifiketi: IVietnam idinga imibiko ye-CNAS; iSaudi Arabia iyalela isitifiketi se-SASO.
3. Isu Lemakethe: Amamodeli aphakathi nendawo (200−500) ayabusa eVietnam/eBrazil, kuyilapho abathengi baseSaudi bekhetha amayunithi amelana nokugqwala aphezulu ($800+).

Umbono Wochwepheshe:

"Izinzwa ze-Optical DO zikhula ngokushesha kusukela ekusetshenzisweni kwezimboni kuya emikhakheni yezolimo kanye nezemvelo, kanti imakethe yomhlaba wonke ikulungele ukudlula amaRandi ayizigidigidi ezimbili ngo-2027."

—ULi Ming, Umhlaziyi, Inhlangano Yokuqapha Amanzi Yomhlaba Wonke

Imithombo Yedatha: I-Alibaba International, Imibiko Yezolimo Zasemanzini Yebhange Lomhlaba, Imibhalo Yethenda Kahulumeni.

Xhumana: Ukuze uthole izixazululo ze-optical DO sensor, vakashela i-Alibaba International noma abahlinzeki bendawo.

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 eyengeziwe yekhwalithi yamanzi ulwazi,
