Imvelaphi yoLawulo loMgangatho waManzi kunye neemfuno zoLawulo lweKlorini eVietnam
Njengelizwe elikhula ngokukhawuleza kwezoshishino nelikhula ezidolophini eMzantsi-mpuma Asia, iVietnam ijongene noxinzelelo oluphindwe kabini kulawulo lwemithombo yamanzi. Izibalo zibonisa ukuba malunga nama-60% amanzi angaphantsi komhlaba kunye nama-40% amanzi angaphezulu eVietnam angcoliswe ngamaqondo ahlukeneyo, kwaye ungcoliseko lweentsholongwane kunye neekhemikhali zezona zinto ziphambili. Kwiinkqubo zokubonelela ngamanzi, i-chlorine eseleyo - njengenxalenye esebenzayo ye-chlorine evela ekubulaweni kweentsholongwane - idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lwamanzi. I-chlorine eseleyo enganelanga ayiphumeleli ukuphelisa iintsholongwane rhoqo kwimibhobho, ngelixa amanqanaba aphezulu anokuvelisa iimveliso zokubulala iintsholongwane ezibangela umhlaza. I-WHO icebisa ukugcina amanqanaba e-chlorine eseleyo phakathi kwe-0.2-0.5mg/L emanzini okusela, ngelixa umgangatho we-QCVN 01:2009/BYT waseVietnam ufuna ubuncinci be-0.3mg/L kwiindawo zokuphela kwemibhobho.
Iziseko zamanzi zaseVietnam zibonisa ukungalingani okukhulu phakathi kwezixeko nasemaphandleni. Iindawo zasezidolophini ezifana neHanoi kunye neHo Chi Minh City zineenkqubo zokubonelela ezipheleleyo kodwa zijongene nemingeni evela kwiipayipi ezindala kunye nongcoliseko lwesibini. Malunga nama-25% abemi basemaphandleni basaswele ukufikelela kumanzi okusela akhuselekileyo, bexhomekeke kakhulu kumanzi acocekileyo okanye amanzi angaphezulu. Olu phuhliso lungalinganiyo ludala iimfuno ezahlukeneyo zobuchwepheshe bokujonga i-chlorine - iindawo zasezidolophini zifuna iinkqubo ze-intanethi ezichanekileyo kakhulu, ngelixa iindawo zasemaphandleni zibeka phambili ukusebenza kakuhle kweendleko kunye nokulula kokusebenza.
Iindlela zokubeka esweni zemveli zihlangabezana nemiqobo emininzi yokuphunyezwa eVietnam:
- Uhlalutyo lwelabhoratri lufuna iiyure ezi-4-6 ngabasebenzi abaqeqeshiweyo
- Ukuthatha iisampulu ngesandla kuthintelwe yijografi ende yaseVietnam kunye neenkqubo zemilambo ezintsonkothileyo
- Idatha engadibaniyo ayiphumeleli ukubonelela ngeenkcukacha eziqhubekayo zokulungiswa kwenkqubo
Ezi zithintelo zibonakale ngakumbi ngexesha leengxakeko ezifana nesiganeko sokuvuza kwe-chlorine ngo-2023 kwipaki yemizi-mveliso kwiphondo laseDong Nai.
Itekhnoloji yesenzi se-chlorine esisele inika izisombululo ezintsha zokujonga amanzi eVietnam. Iisenzi zanamhlanje zisebenzisa imigaqo ye-electrochemical (i-polarography, i-voltage engaguqukiyo) okanye imigaqo ye-optical (i-DPD colorimetry) ukulinganisa ngokuthe ngqo i-chlorine ekhululekileyo nepheleleyo, idlulisela idatha yexesha langempela ngoqhagamshelo olunentambo okanye olungenazingcingo. Xa kuthelekiswa neendlela zemveli, le teknoloji inika impendulo ekhawulezayo (<30 seconds), ukuchaneka okuphezulu (±0.02mg/L), kunye nokugcinwa okuncinci - okufanelekileyo ngakumbi kwimozulu yetropiki yaseVietnam kunye neemfuno zokujonga ezikude.
Amaphulo aseVietnam e-“Smart City” kunye nenkqubo kazwelonke ethi “Clean Water” abonelela ngenkxaso yomgaqo-nkqubo wokusetyenziswa kwe-chlorine sensor.Ingxelo yoPhando loPhuhliso lweShishini kunye noTyalo-mali oluyiResidual Chlorine Analyzer yaseVietnamibonisa ukuba urhulumente uceba ukuphucula iinkqubo zokubeka esweni kwizixeko ezikhulu, ebeka phambili izixhobo zokubeka esweni i-chlorine kwi-intanethi. Kwangaxeshanye, uMphathiswa wezeMpilo wonyuse amaxesha okubeka esweni afunekayo ukusuka ngenyanga ukuya kwimihla ngemihla kwiindawo ezibalulekileyo, nto leyo eqhubela phambili imfuno yetekhnoloji yexesha langempela.
Itheyibhile: Imida yeChlorine eseleyo kwiMigangatho yoMgangatho waManzi eVietnam

Imarike yezinzwa yaseVietnam ibonisa ukuhlalisana kwamazwe ngamazwe, kunye neemveliso eziphambili ezifana neLAR yaseJamani kunye neHACH yaseMelika zilawula amacandelo aphezulu ngelixa abavelisi baseTshayina abafana neXi'an Yinrun (ERUN) kunye neShenzhen AMT befumana isabelo semarike ngamaxabiso akhuphisanayo. Okuphawulekayo kukuba, iinkampani zaseVietnam zingena ekuveliseni izinzwa ngokusebenzisa ubudlelwane betekhnoloji, njengezinzwa ezingabizi kakhulu zenkampani eseHanoi ezivavanywe ngempumelelo kwiiprojekthi zamanzi zezikolo zasemaphandleni.
Ukwamkelwa komntwana kwindawo ohlala kuyo kujongene nemingeni emininzi yokuziqhelanisa:
- Ukufuma kwetropiki okuchaphazela izixhobo ze-elektroniki
- Ubushushu obuphezulu obuchaphazela ukuchaneka kokukhanya
- Umbane okhoyo ngamaxesha athile kwiindawo zasemaphandleni
Abavelisi baphendule ngokhuseleko lwe-IP68, ukucoca ngokuzenzekelayo, kunye neendlela zokusebenzisa amandla elanga ukuphucula ukuthembeka kwiimeko ezinzima zaseVietnam.
Imigaqo yoBugcisa kunye noLungiso oluKhethekileyo lwaseVietnam
Izinzwa zeklorine eziseleyo zisebenzisa iindlela ezintathu eziphambili zokufumanisa eVietnam, nganye ifanelekile kwiindawo ezahlukeneyo kunye nokusetyenziswa kwazo.
Izinzwa zePolarographic, eziboniswe yi-ERUN-SZ1S-A-K6, zilawula ukufakelwa koomasipala nakwimizi-mveliso. Ezi zilinganisa umahluko wangoku phakathi kwee-electrodes ezisebenzayo kunye neereferensi (ngesiqhelo iinkqubo ze-electrode zegolide), ezibonelela ngocoselelo oluphezulu (±1%FS) kunye nokuphendula ngokukhawuleza (<30s). KwiSitishi Samanzi saseHo Chi Minh City No.3, iziphumo zePolarographic zibonise ukuhambelana kwe-98% nemigangatho ye-DPD yelebhu. Iindlela zokucoca ngokuzenzekelayo ezidibeneyo (iinkqubo zokuxubha) zandisa amaxesha okugcina ukuya kwiinyanga ezi-2-3 - okubaluleke kakhulu kumanzi atyebileyo e-algae eVietnam.
Izinzwa ze-voltage ezihlala zihleli (umz., iinkqubo ze-LAR) zibalaseleyo kwizicelo zamanzi amdaka ezinzima. Ngokusebenzisa amandla azinzileyo kunye nokulinganisa umbane ophumayo, zibonisa ukumelana okuphezulu kokuphazamiseka ngokuchasene ne-sulfides kunye ne-manganese - ebaluleke kakhulu kumanzi anzima asemazantsi eVietnam. Isityalo samanzi amdaka saseCan Tho AKIZ sisebenzisa obu buchwephesha kunye neenkqubo zeNitriTox ukugcina i-chlorine ephumayo kwi-0.5-1.0mg/L.
Izinzwa ze-optical colorimetric ezifana neBlueview's ZS4 zibonelela ngeemfuno zeeparameter ezininzi ezicwangciselwe uhlahlo lwabiwo-mali. Nangona zicotha (imizuzu emi-2-5), umthamo wazo weeparameter ezininzi ezisekelwe kwi-DPD (i-pH/turbidity ngaxeshanye) unciphisa iindleko zeenkonzo zephondo. Uphuhliso lwe-Microfluidic lunciphise ukusetyenziswa kwee-reagent nge-90%, nto leyo eyenza kube lula ukugcina izinto zisemgangathweni.
