1. Imvelaphi
IVietnam, indawo ephambili kwezolimo nakwimizi-mveliso kuMzantsi-mpuma weAsia, ijongene nemingeni enzima yokungcoliswa kwamanzi, ngakumbi ungcoliseko lwezinto eziphilayo (COD) kunye nezinto eziqinileyo ezixhonyiweyo (ukungcoliswa kwamanzi) emilanjeni, emachibini, nakwiindawo ezikunxweme. Ukuhlolwa komgangatho wamanzi ngokwesiko kuxhomekeke ekuthathweni kweesampuli zelebhu, ezinengxaki yokulibaziseka kwedatha, iindleko eziphezulu zabasebenzi, kunye nokugutyungelwa okuncinci.
Ngowama-2022, iSebe leMithombo yeNdalo kunye neNdalo laseVietnam (i-MONRE) lasebenzisa izixhobo zokuvavanya umgangatho wamanzi ezisebenzisa iiparameter ezininzi kwiindawo ezibalulekileyo zamanzi kulo lonke iRed River Delta kunye neMekong Delta, ligxile kwiMfuno yeOksijini yeKhemikhali (i-COD) kunye nokubeka iliso kwiTurbidity ukuze kuvumeleke ukuba kubekho izilumkiso zongcoliseko ngexesha langempela kunye nokulandelela imithombo.
2. Isisombululo soBugcisa
(1) Iinkcukacha zeSensor kunye neempawu
- I-COD Sensor: Isebenzisa i-UV-Vis spectroscopy (akukho reagents ifunekayo), umlinganiselo wexesha langempela (uluhlu lwe-0-500 mg/L, ukuchaneka kwe-±5%).
- I-Turbidity Sensor: Isekelwe kumgaqo wokukhanya okusasazekayo we-90° (0-1000 NTU, ±2% ukuchaneka), uyilo oluchasene nokungcola kwezinto eziphilayo.
- Inkqubo Edibeneyo: Idibanisa izinzwa kunye nothumelo olungenazingcingo lweLoRa/NB-IoT, ilayisha idatha kwiqonga lelifu elinoqikelelo longcoliseko olusebenzisa i-AI.
(2) Iimeko zokusasazwa
- Iindawo zokukhupha amanzi kwimizi-mveliso (eBac Ninh, kumaPhondo aseDong Nai)
- Izityalo zokunyanga amanzi amdaka zasezidolophini (eHanoi, eHo Chi Minh City)
- Iindawo zokulima iintlanzi (iMekong Delta)
3. Iziphumo eziphambili
(1) Izaziso zoNgcoliseko lweXesha langempela
- Ngowama-2023, i-sensor eBac Ninh yafumanisa ukunyuka kwe-COD ngequbuliso (ukusuka kwi-30mg/L ukuya kwi-120mg/L), nto leyo eyabangela isilumkiso ezenzekelayo. Abasemagunyeni balandelela umthombo kwifektri yelaphu eyaphula imithetho yokukhupha, nto leyo eyakhokelela kwizohlwayo kunye nezenzo zokulungisa.
- Idatha yokuguquka kobushushu incede ekwenzeni ngcono idosi ye-flocculant kwizityalo zamanzi okusela ngexesha lokunyuka kwe-monsoon silt, yanciphisa iindleko zonyango nge-10%.
(2) Ukuphucula Ulimo Lwezilwanyana Zasemanzini
KwiPhondo laseBen Tre, iinethiwekhi zesensor zihlengahlengisa ngokuguquguqukayo ii-aerator ukugcina i-turbidity engaphantsi kwama-20 NTU kunye ne-COD engaphantsi kwama-15mg/L, nto leyo enyusa amazinga okusinda kwee-shrimp nge-18%.
(3) Uhlalutyo lweNdlela eNtsha yexesha elide
Idatha yembali ibonise ukwehla kwama-22% kumanqanaba e-COD aphakathi (2022–2024) kwiindawo ezikuMlambo iRed River, nto leyo eqinisekisa iSicwangciso soLawulo lokuNgcoliswa kwamanzi saseVietnam sika-2021–2030.
4. Imingeni kunye neZisombululo
| Umngeni | Isisombululo |
|---|---|
| Ukwakheka kwe-biofilm kwiisensa | Iibhrashi zokucoca ngokuzenzekelayo + ukulinganisa ikota nganye |
| Ukugcwala kwamanzi ngexesha lezikhukula | Ukusebenza kwendlela yokubuyisela i-infrared |
| Amandla angazinzileyo kwiindawo ezikude | Iiphaneli zelanga + i-supercapacitor backup |
5. Izicwangciso zexesha elizayo
- Ithagethi ka-2025: Ukwandisa iindawo zokubeka esweni ukusuka kwi-150 ukuya kwi-500, kuquka izidibi zemilambo ezinkulu ezili-12.
- Uphuculo lobuchwephesha: Uvavanyo lwesathelayithi olukude kunye nokuhlanganiswa kwesenzi somhlaba sokulandelela ungcoliseko olukhulu.
- Ukuhlanganiswa kweMigaqo-nkqubo: Ukwabelana ngedatha ngqo namapolisa okusiNgqongileyo aseVietnam ukuze kukhawuleziswe ukunyanzeliswa kwayo.
6. Izinto ezibalulekileyo ekufuneka ziqwalaselwe
Ityala laseVietnam libonisa indlela iinkqubo ze-COD-turbidity multi-sensor ezibonelela ngayo ixabiso elibalulekileyo kwimithetho yemizi-mveliso, ukhuseleko lwamanzi okusela, kunye nokufuywa kwamanzi, zibonelela ngesisombululo esingabizi kakhulu nesisebenza ngexesha langempela kumazwe asaphuhlayo.
Singabonelela ngezisombululo ezahlukeneyo
1. Imitha ephathwayo yomgangatho wamanzi weparameter ezininzi
2. Inkqubo ye-Floating Buoy yomgangatho wamanzi we-multi-parameter
3. Ibrashi yokucoca ngokuzenzekelayo yesixhobo sokuvavanya amanzi esineeparameter ezininzi
4. Iseti epheleleyo yeeseva kunye nemodyuli engenazingcingo yesoftware, ixhasa i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
