I-Optical Dissolved Oxygen (ODO) izinzwa, ezikwabizwa ngokuba zii-fluorescence-based sensors, zibuchwephesha bale mihla obuchasene neendlela zemveli zemembrane electrode (Clark cells). Into yabo ephambili kukusetyenziswa kwe-fluorescence quenching ukulinganisa ukuxinwa kwe-oksijini echithiweyo emanzini.
UmGaqo wokuSebenza:
Incam ye-sensor igqunywe nge-membrane efakwe ngedayi ye-fluorescent. Xa le dayi ivuyiswa bubude obukhethekileyo bokukhanya okuluhlaza, ikhupha ukukhanya okubomvu. Ukuba iimolekyuli ze-oksijini zikhona emanzini, zingqubana kunye neemolekyuli zedayi ezinovuyo, ezibangela ukunciphisa ubuninzi be-fluorescence kunye nobomi obufutshane be-fluorescence. Ngokulinganisa olu tshintsho kubomi be-fluorescence okanye ubunzima, i-concentration ye-oksijeni echithiweyo ingabalwa ngokuchanekileyo.
Iimpawu eziphambili:
- Akukho ukusetyenziswa kweoksijini, akukho Electrolyte:
- Lo ngowona mahluko usisiseko kwindlela ye-membrane electrode. Izinzwa ze-Optical aziyidli i-oksijini kwisampulu, zibonelela ngeziphumo ezichanekileyo, ngakumbi kwi-low-flow or static body body.
- Akukho mfuneko yokutshintsha i-electrolytes okanye i-membrane, ukunciphisa kakhulu ukugcinwa.
- Ugcino oluphantsi, uzinzo oluPhezulu:
- Akukho miba nge-membrane clogging, ityhefu ye-electrode, okanye ungcoliseko lwe-electrolyte.
- Amathuba amade okulinganisa, asoloko efuna ulungelelwaniso rhoqo emva kweenyanga ezimbalwa okanye nangaphezulu.
- Ukuphendula ngokukhawuleza kunye nokuchaneka okuphezulu:
- Impendulo ekhawulezayo kakhulu kwiinguqu kwi-oksijini enyityilisiweyo, evumela ukubanjwa kwexesha lokwenyani lokutshintsha okuguquguqukayo komgangatho wamanzi.
- Imilinganiselo ayichatshazelwa sisantya sokuqukuqela okanye izinto eziphazamisayo ezifana neesulfides, ezinika ukuchaneka okugqwesileyo kunye nokuzinza xa kuthelekiswa neendlela eziqhelekileyo.
- Ubuncinci beXesha Elide Ukuqhuba:
- Iimpawu zedayi ye-fluorescent zizinzile kakhulu, ezibangela ukuba i-signal drift encinci kunye nokuqinisekisa ukuthembeka kokulinganisa ixesha elide.
- Ukusebenziseka ngokulula:
- Ngokuqhelekileyo iplagi kunye nokudlala, ngaphandle kwexesha elide le-polarization elifunekayo emva kokuqaliswa; ilungele umlinganiselo wangoko.
Izinto ezingeloncedo:
- Iindleko eziPhakamileyo zokuqala: Ngokuqhelekileyo zibiza kakhulu kuneenzwa ze-membrane zemveli.
- I-Fluorescent Membrane ine-Finite Lifespan: Nangona ihlala ixesha elide (ngokuqhelekileyo i-1-3 iminyaka), i-membrane iya ekugqibeleni i-photodegrade okanye ihlanjululwe kwaye ifune ukutshintshwa.
- Ukunyanzeliswa okunokwenzeka ngaMaoyile kunye ne-Algae: Ukugqithisa okunzima kweoli okanye i-biofouling kwi-sensor surface inokuphazamisa ukuvuswa kokukhanya kunye nokwamkelwa, okufunekayo ukucocwa.
2. Iimeko zesicelo
Ngenxa yeempawu zabo ezibalaseleyo, izinzwa zeoksijini ezinyityilisiweyo zisetyenziswa ngokubanzi kwimimandla eyahlukeneyo efuna uqwalaselo lwe-DO oluqhubekayo noluchanekileyo:
- Iindawo zokucocwa kwamanzi amdaka:
- Isicelo esibalulekileyo. Isetyenziselwa ukubeka esweni i-DO kwiitanki zokuphefumla kunye nemimandla ye-aerobic/anaerobic ukunyusa umoya, ukwenza ulawulo oluchanekileyo lokonga amandla kunye nokuphuculwa kokusebenza konyango.
- Ukujongwa koMzimba waManzi eNdalo (imilambo, amachibi, amadama):
- Isetyenziswa kwizikhululo zokujonga indalo ukuvavanya amandla okuzicoca emzimbeni wamanzi, ubume be-eutrophication, kunye ne-hypoxia enokubakho, ukubonelela ngedatha yokhuseleko lwendalo.
- Ulimo lwasemanzini:
- I-DO yindlela yokuphila yasemanzini. Izinzwa ze-Optical zivumela ukubeka iliso kwe-24/7 kumachibi kunye namatanki. Ziyakwazi ukuqalisa ii-alamu kwaye zivule ngokuzenzekelayo ii-aerators xa amanqanaba ehla kakhulu, ukuthintela ukubulawa kweentlanzi kunye nokukhusela imveliso.
- Uphando lwezeNzululwazi:
- Isetyenziswa kuphando lwe-oceanographic, izifundo ze-limnological, kunye neemvavanyo ze-ecotoxicology apho ukuchaneka okuphezulu, uphazamiseko oluphantsi lwedatha ye-DO ibalulekile.
- Amanzi eNkqubo yoShishino:
- Kwiinkqubo ezifana neplanti yamandla kunye namanzi okupholisa isityalo sekhemikhali, ukubeka iliso kwi-DO ukulawula ukubola kunye ne-biofouling.
3. I-Application Case Study kwiiPhilippines
Njengelizwe leziqithi, uqoqosho lwePhilippines luxhomekeke kakhulu kwi-aquaculture kunye nokhenketho, ngelixa ikwajongene nemiceli mngeni yongcoliseko lwamanzi evela ezidolophini. Ke ngoko, ukujonga umgangatho wamanzi, ngakumbi ioksijini enyibilikileyo, kubaluleke kakhulu.
Uphononongo: I-Smart DO yokuBeka iliso kunye neNkqubo ye-Aeration kwiNdawo zaseLaguna de Bay Aquaculture
Imvelaphi:
ILaguna de Bay lelona chibi likhulu kwiiPhilippines, neendawo ezingqongileyo zibalulekile kulimo lwaselwandle, ikakhulu kwiTilapia kunye neMilkfish (Bangus). Nangona kunjalo, eli chibi lijongene nezoyikiso ezivela kwi-eutrophication. Ngexesha leenyanga ezishushu zasehlotyeni, ukuhluthwa kwamanzi kunokukhokelela kwi-hypoxia kumaleko anzulu, ngokufuthi kubangela ukubulawa kweentlanzi ezinkulu ("intlanzi iyabulala"), okukhokelela kwilahleko enkulu yezoqoqosho kumafama.
Isisombululo sesicelo:
I-Bureau of Fisheries and Aquatic Resources (BFAR), ngokusebenzisana noorhulumente basekhaya, yakhuthaza ukusetyenziswa kwenkqubo ekrelekrele yokuhlola umgangatho wamanzi kunye nenkqubo yokulawula esekelwe kwi-optical disolved sensors yeoksijini kwiifama ezinkulu zorhwebo kunye neendawo eziphambili zechibi.
Amacandelo eNkqubo kunye nokuhamba komsebenzi:
- IiNodi zokuBeka iliso: Ii-buoys zomgangatho wamanzi ezininzi zeparameter ezixhotyiswe nge-optical DO sensors zafakwa kwiindawo ezahlukeneyo kumachibi eentlanzi (ingakumbi kwiindawo ezinzulu) kunye neendawo eziphambili echibini. Ezi zoluvo zikhethwe ngenxa yokuba:
- ULondolozo oluphantsi: Ukusebenza kwabo ixesha elide-simahla kukulungele iindawo ezinabasebenzi bobuchwephesha abambalwa.
- Ukuxhathisa kuphazamiseko: Ukungaphumeleli kancinci ekungcoleni emanzini atyebileyo kunye namanzi amdaka.
- Idatha yexesha langempela: Iyakwazi ukubonelela ngedatha yonke iminithi, evumela ukubonwa ngokukhawuleza kwe-DO drops.
- Ugqithiso lweeNkcukacha: Idatha yeSensor ihanjiswa ngexesha lokwenyani ngeenethiwekhi ezingenazingcingo (umzekelo, iGPRS/4G okanye iLoRa) ukuya kwiqonga lelifu kunye neeapps eziphathwayo zamafama.
- Ulawulo olulumkileyo kunye nesilumkiso kwangethuba:
- Icala le-Platform: Iqonga lelifu limiselwe kunye ne-DO alarm thresholds (umzekelo, ngaphantsi kwe-3 mg / L).
- Icala labasebenzisi: Amafama afumana izilumkiso ezivakalayo/ezibonwayo, iSMS, okanye izaziso zeapp.
- Ulawulo oluzenzekelayo: Inkqubo inokwenza ngokuzenzekelayo i-aerators de amanqanaba e-DO abuyiselwe kuluhlu olukhuselekileyo.
Iziphumo:
- Ukunciphisa Ukufa Kweentlanzi: Izilumkiso zakwangoko kunye ne-aeration ngokuzenzekelayo zikhusele ngempumelelo iintlanzi ezininzi zokubulala iziganeko ezibangelwa amanqanaba aphantsi e-DO ngexesha lobusuku okanye ekuseni.
- UkuSebenza okuPhuculweyo kokuFama: Amafama angakwazi ukulawula ukutya kunye nokungenisa umoya ngakumbi ngokwesayensi, ukunciphisa iindleko zombane (ngokuphepha ukusebenza kwe-24/7盲目 kwe-aerators) kunye nokuphucula uhlengahlengiso lokuguqulwa kokutya kunye namazinga okukhula kweentlanzi.
- Idatha yoLawulo lokusiNgqongileyo: Izikhululo zokubeka esweni echibini zibonelela nge-BFAR ngedatha ye-DO yexesha elide ye-spatiotemporal, inceda ukuhlalutya iintsingiselo ze-eutrophication kunye nokuqulunqa imigaqo-nkqubo yolawulo lwechibi lwenzululwazi.
Isishwankathelo:
Kumazwe asaphuhlayo afana nePhilippines, apho i-aquaculture ijongene nemingcipheko ephezulu kunye neziseko ezingundoqo zinokucelwa umngeni, i-optical dissolved oxygen sensors ibonakalise ukuba sisixhobo esifanelekileyo sezobuchwepheshe sokuchaneka kwe-aquaculture kunye nokulawula okusingqongileyo okuhlakaniphile ngenxa yokuqina kwazo, ukugcinwa okuphantsi, kunye nokuthembeka okuphezulu. Abancedi nje kuphela amafama ukunciphisa imingcipheko kwaye banyuse ingeniso kodwa babonelela ngenkxaso yedatha enamandla ukukhusela izinto eziphilayo zasemanzini ezixabisekileyo zasePhilippine.
