Indawo: eSingapore
Njengeziko lezemali lehlabathi elinoshishino oluqinileyo, iSingapore izibophelele ekugcineni imigangatho ephezulu yokusingqongileyo ngelixa ikhuthaza ukukhula koqoqosho. Enye yezinto ezibalulekileyo ekufezekiseni loo migangatho kulawulo lwamanzi kukujonga ngokufanelekileyo umgangatho wamanzi, ingakumbi amanqanaba eoksijini enyibilikisiweyo (i-DO) abalulekileyo kwiinkqubo zendalo zasemanzini. Ukunyuka kweenzwa zeoksijini enyibilikisiweyo ebonakalayo kuye kwavela njengetekhnoloji eguqulayo ephucula ukujonga umgangatho wamanzi kumashishini ahlukeneyo eSingapore.
Ukuqonda i-oksijini enyibilikisiweyo kunye nokubaluleka kwayo
Ioksijini enyibilikisiweyo ibalulekile ekusindeni kwezidalwa zasemanzini; luphawu oluphambili lomgangatho wamanzi kunye nempilo yendalo. Kwimizi-mveliso efana nonyango lwamanzi amdaka, ukulima amachibi, kunye nokulungiswa kokutya, ukugcina amanqanaba e-DO afanelekileyo akubalulekile nje kuphela ekuthobeleni indalo kodwa nakwindlela yokusebenza kakuhle kunye nokuzinza kwemisebenzi.
Iindlela zemveli zokulinganisa ioksijini enyibilikisiweyo ziquka ukusebenzisa ii-polarographic sensors, ezinokuphazanyiswa zezinye izinto, zifune ukulinganiswa rhoqo, kwaye zinokuba nzima ukuzigcina. Ngokwahlukileyo koko, ii-optical dissolved oxygen sensors zisebenzisa itekhnoloji yokukhanya ukulinganisa amanqanaba eoksijini ngendlela ethembekileyo nechanekileyo.
Iingenelo zeeSensors zeOxygen ezinyibilikisiweyo zeOptical

Ukubeka esweni ngexesha langempela:Ukukwazi ukuhambisa idatha ngexesha langempela kwenza amashishini akwazi ukuvavanya umgangatho wamanzi ngokukhawuleza, nto leyo ekhokelela ekwenzeni izigqibo ezinolwazi oluthe kratya. Umzekelo, imisebenzi yokulima iintlanzi inokulungisa amanqanaba eoksijini ngokukhawuleza ukuqinisekisa iimeko ezifanelekileyo zempilo yeentlanzi.
-
Impembelelo kwiNdalo:Ukuhlolwa okuphuculweyo kweoksijini enyibilikisiweyo kunceda amashishini ukunciphisa umngcipheko wendalo ngokuqinisekisa ukuthotyelwa kwemigangatho yomgangatho wamanzi kunye nokunciphisa umngcipheko weziganeko zongcoliseko. La manyathelo asebenzayo ahambelana neenjongo zaseSingapore zophuhliso oluzinzileyo kunye nokugcinwa kokusingqongileyo.
Ukuguqula Amashishini Aphambili
1. Unyango lwamanzi amdaka:I-Arhente yeSizwe yaManzi yaseSingapore (i-PUB) igxininisa kakhulu ekulawulweni kwamanzi amdaka ukuze kugcinwe umgangatho weendawo zamanzi. Ukuhlanganiswa kwee-sensors ze-oksijini ezinyibilikisiweyo ezibonakalayo kwiindawo zonyango kuye kwaphucula ukuchaneka kolawulo lwe-oksijini kwiinkqubo zonyango lwebhayoloji, nto leyo ekhokelela ekususweni ngcono kokungcola kunye nomgangatho ongcono wokungcola.
2. Ukulima iintlanzi zasemanzini:Njengoko iSingapore izama ukuzimisa njengesikhungo esiphambili sokufuya iintlanzi ezihlala ixesha elide, ukuqaliswa kwee-optical sensors kuye kwaguqula iindlela zokufuya iintlanzi. Ngokugcina amanqanaba e-oxygen anyibilikisiweyo afanelekileyo, abaqhubi be-aquaculture banokuphucula amazinga okukhula kweentlanzi kwaye baphucule isivuno ngokubanzi, ngaloo ndlela benegalelo kukhuseleko lokutya kunye nokuzinza koqoqosho.
3. Ukulungiswa kokutya:Kwishishini lokutya, umgangatho wamanzi ubalulekile kwiinkqubo ezahlukeneyo, kuquka ukuhlanjwa kwemveliso kunye nokuxuba izithako. Izinzwa zeoksijini ezinyibilikisiweyo ziqinisekisa ukuba amanzi asetyenziswa ekuvelisweni ahlangabezana nemigangatho yokhuseleko kunye nomgangatho, ekugqibeleni ekhokelela kumgangatho ophezulu wemveliso kunye nokunciphisa inkunkuma.
