Iisensa ze-Optical Dissolved Oxygen (ODO), ezaziwa ngokuba ziisensa ezisekelwe kwi-fluorescence, zibuchwepheshe bale mihla obuchasene neendlela ze-membrane electrode zemveli (ii-Clark cells). Eyona nto iphambili kuzo kukusebenzisa i-fluorescence quenching ukulinganisa uxinzelelo lwe-oxygen enyibilikisiweyo emanzini.
Umgaqo Wokusebenza:
Incam yesinzwa igqunywe yi-membrane efakwe idayi ye-fluorescent. Xa le dayi ivuselelwa bubude obuthile bokukhanya okuluhlaza okwesibhakabhaka, ikhupha ukukhanya okubomvu. Ukuba kukho iimolekyuli zeoksijini emanzini, ziyangqubana neemolekyuli zedayi ezivuselelwe, nto leyo ebangela ukwehla kobukhali be-fluorescence kunye nobomi obufutshane be-fluorescence. Ngokulinganisa olu tshintsho lobomi be-fluorescence okanye ubukhali, ubukhali be-oxygen enyibilikisiweyo bunokubalwa ngokuchanekileyo.
Iimpawu eziphambili:
- Akukho kusetyenziswa kweoksijini, akukho electrolyte:
- Lo ngowona mahluko uphambili kwindlela ye-membrane electrode. Ii-optical sensors azisebenzisi ioksijini kwisampuli, nto leyo enika iziphumo ezichanekileyo ngakumbi, ingakumbi kwiindawo zamanzi ezingasebenzi kakuhle okanye ezingasebenziyo.
- Akukho mfuneko yokutshintsha ii-electrolytes okanye ii-membrane, nto leyo enciphisa kakhulu ukugcinwa kwazo.
- Ulondolozo oluphantsi, Uzinzo oluphezulu:
- Akukho ngxaki ngokuvaleka kwe-membrane, ukutyhefwa yi-electrode, okanye ungcoliseko lwe-electrolyte.
- Amaxesha amade okulinganisa, adla ngokufuna ukulinganisa rhoqo emva kweenyanga ezimbalwa okanye nangaphezulu.
- Impendulo Ekhawulezileyo Nokuchaneka Okuphezulu:
- Impendulo ekhawulezileyo kakhulu kutshintsho kwioksijini enyibilikisiweyo, nto leyo evumela ukuba kuthathwe utshintsho lomgangatho wamanzi ngexesha langempela.
- Ukulinganisa akuchatshazelwa yisantya sokuhamba okanye izinto eziphazamisayo ezifana neesulfide, nto leyo enika ukuchaneka okuphezulu kunye nozinzo xa kuthelekiswa neendlela zemveli.
- Ukuhamba kancinci kwexesha elide:
- Iimpawu zedayi ye-fluorescent zizinzile kakhulu, nto leyo ebangela ukuba isignali ihambe kancinci kwaye iqinisekise ukuthembeka komlinganiselo wexesha elide.
- Ukusebenziseka lula:
- Ngokwesiqhelo i-plug-and-play, ngaphandle kwexesha elide le-polarization elifunekayo emva kokuqalisa; ilungele ukulinganiswa kwangoko.
Iingxaki:
- Ixabiso lokuqala eliphezulu: Lidla ngokuba libiza kakhulu kunezinzwa ze-membrane electrode zemveli.
- I-Fluorescent Membrane inexesha elide lokuphila: Nangona ihlala ixesha elide (ngesiqhelo iminyaka eyi-1-3), i-membrane ekugqibeleni iya kubola okanye ingcole kwaye ifune ukutshintshwa.
- Ungcoliseko Olunokwenzeka Ngeeoyile kunye neAlgae: Ukufakwa kakhulu kweoyile okanye i-biofouling kumphezulu we-sensor kunokuphazamisana nokukhanya kunye nokwamkelwa, nto leyo ebangela ukuba kucocwe.
2. Imizekelo yesicelo
Ngenxa yeempawu zazo ezibalaseleyo, ii-optical dissolved oxygen sensors zisetyenziswa kakhulu kwiindawo ezahlukeneyo ezifuna ukubekwa esweni kwe-DO rhoqo nangokuchanekileyo:
- Izityalo Zokucoca Amanzi Amdaka:
- Isicelo esibalulekileyo. Sisetyenziselwa ukujonga i-DO kwiitanki zomoya kunye neendawo ze-aerobic/anaerobic ukuze kuphuculwe umoya, okuvumela ulawulo oluchanekileyo lokonga amandla kunye nokusebenza kakuhle konyango.
- Ukubeka esweni umzimba wamanzi wendalo (imilambo, amachibi, amadama okugcina amanzi):
- Isetyenziswa kwizikhululo zokujonga okusingqongileyo ukuvavanya amandla okuzihlambulula amanzi, imeko ye-eutrophication, kunye ne-hypoxia enokubakho, inika idatha yokukhuselwa kwendalo.
- Ukulima iintlanzi:
- I-DO yindlela yokuphila kwezilwanyana zasemanzini. Iisensa zokubona zivumela ukujonga iiyure ezingama-24/7 kumachibi nakwiitanki. Zinokubangela ii-alamu kwaye zivule ngokuzenzekelayo ii-aerator xa amazinga ehla kakhulu, nto leyo ethintela ukubulawa kweentlanzi kwaye ikhusele imveliso.
- Uphando lwezeNzululwazi:
- Isetyenziswa kuphando lwe-oceanographic, izifundo ze-limnological, kunye novavanyo lwe-ecotoxicology apho idatha ye-DO echanekileyo kakhulu, engaphazanyiswa kakhulu ibalulekile.
- Amanzi eNkqubo yoShishino:
- Kwiinkqubo ezifana neziko lombane kunye namanzi okupholisa izityalo zeekhemikhali, kubeka esweni i-DO ukulawula ukugqwala kunye nokubola kwezinto eziphilayo.
3. Isifundo seTyala leSicelo ePhilippines
Njengelizwe elihlala kwiindawo ezininzi, uqoqosho lwasePhilippines luxhomekeke kakhulu ekukhuliseni iintlanzi kunye nokhenketho, ngelixa lujongene nemingeni yongcoliseko lwamanzi olubangelwa kukukhula kwezixeko. Ke ngoko, ukujonga umgangatho wamanzi, ngakumbi ioksijini enyibilikisiweyo, kubaluleke kakhulu.
Isifundo seTyala: Inkqubo yokubeka esweni i-Smart DO kunye neNkqubo yoMoya kwiindawo zaseLaguna de Bay Aquaculture
Imvelaphi:
ILaguna de Bay yeyona chibi likhulu ePhilippines, kwaye iindawo ezingqongileyo zibalulekile ekukhuliseni iintlanzi, ikakhulu kwiTilapia kunye neMilkfish (Bangus). Nangona kunjalo, ichibi lijongene nomngcipheko wokutya kakhulu. Ngexesha leenyanga zasehlotyeni ezishushu, ukuhluma kwamanzi kunokukhokelela kwi-hypoxia kwiindawo ezinzulu, okuhlala kubangele ukubulawa kweentlanzi ezininzi ("ukubulawa kweentlanzi"), okubangela ilahleko enkulu kwezoqoqosho kubalimi.
Isisombululo sesicelo:
I-Bureau of Fisheries and Aquatic Resources (i-BFAR), ngokubambisana noorhulumente basekuhlaleni, ikhuthaze ukusetyenziswa kwenkqubo yokujonga nokulawula umgangatho wamanzi ekrelekrele esekwe kwiisensa zeoksijini ezinyibilikisiweyo ezibonakalayo kwiifama zorhwebo ezinkulu nakwiindawo eziphambili zechibi.
Izinto zeNkqubo kunye nokuhamba komsebenzi:
- IiNode zokubeka esweni: Ii-buoy zomgangatho wamanzi ezineeparameter ezininzi ezixhotyiswe ngee-optical DO sensors zibekwe kwiindawo ezahlukeneyo kumachibi eentlanzi (ingakumbi kwiindawo ezinzulu) nakwiindawo ezibalulekileyo echibini. Ezi sensors zikhethwe ngenxa yokuba:
- Ulondolozo Oluphantsi: Ukusebenza kwazo ixesha elide ngaphandle kolondolozo kulungele iindawo ezinabasebenzi bobuchwephesha abambalwa.
- Ukuxhathisa Ukuphazamiseka: Akulula ukusilela ngenxa yokungcola emanzini achumileyo namanzi amdaka afuywayo.
- Idatha yexesha langempela: Iyakwazi ukubonelela ngedatha yonke iminithi, ivumela ukubonwa ngokukhawuleza kwe-DO drops ngequbuliso.
- Ukuhanjiswa kwedatha: Idatha yesensor idluliselwa ngexesha langempela ngeenethiwekhi ezingenazingcingo (umz., i-GPRS/4G okanye i-LoRa) kwiqonga lelifu kunye neeapps zeselula zamafama.
- Ulawulo olukrelekrele kunye nesilumkiso sakwangoko:
- Icala leQonga: Iqonga lelifu limiselwe ngemida ye-alamu ye-DO (umz., ngaphantsi kwe-3 mg/L).
- Icala Lomsebenzisi: Abalimi bafumana izaziso ezivakalayo/ezibonakalayo, iiSMS, okanye izaziso zeapp.
- Ulawulo Oluzenzekelayo: Inkqubo ingenza ngokuzenzekelayo ii-aerator zisebenze de amanqanaba e-DO abuyiselwe kuluhlu olukhuselekileyo.
Iziphumo:
- Ukuncipha Kokufa Kweentlanzi: Izilumkiso zakwangoko kunye nokungena komoya ngokuzenzekelayo kuthintele ngempumelelo iziganeko ezininzi zokubulawa kweentlanzi ezibangelwa ngamanqanaba aphantsi kakhulu e-DO ebusuku okanye kusasa.
- Ukuphucula Ukusebenza Kokulima: Abalimi banokukwazi ukulawula ukondla nokungenisa umoya ngokwesayensi, banciphise iindleko zombane (ngokuphepha ukusebenza kwezixhobo zokungenisa umoya iiyure ezingama-24 ngosuku, iintsuku ezisi-7 ngosuku) kwaye baphucule umlinganiselo wokuguqulwa kokutya kunye namazinga okukhula kweentlanzi.
- Idatha yoLawulo lweNdalo: Izikhululo zokubeka esweni echibini zibonelela i-BPAR ngedatha ye-DO yexesha elide yendawo, inceda ukuhlalutya iindlela zokuhluma kwe-eutrophication kunye nokwenza imigaqo-nkqubo yolawulo lwechibi yesayensi ngakumbi.
Isishwankathelo:
Kumazwe asaphuhlayo afana nePhilippines, apho ukulima iintlanzi kujongana nemingcipheko ephezulu kwaye iziseko zophuhliso zinokuchatshazelwa, izinzwa zeoksijini ezinyibilikisiweyo ezibonakalayo zibonakalise ukuba sisixhobo esifanelekileyo sobuchwepheshe bokulima iintlanzi ngokuchanekileyo kunye nolawulo lokusingqongileyo olukrelekrele ngenxa yokuqina kwazo, ukugcinwa kwazo okuncinci, kunye nokuthembeka okuphezulu. Azincedi nje kuphela abalimi ukunciphisa iingozi kunye nokwandisa ingeniso kodwa zikwabonelela ngenkxaso yedatha enamandla yokukhusela iinkqubo eziphilayo zasemanzini ezixabisekileyo zasePhilippines.
