Imvelaphi yokuHlolwa koMgangatho waManzi kunye neeMfuno zoLawulo lweChlorine eVietnam
Njengelizwe elikhula ngokukhawuleza kwimizi-mveliso kunye nelizwe lase-Asia-mpuma le-Asia, iVietnam ijongene noxinzelelo olubini kulawulo lobutyebi bamanzi. Ubalo lubonisa malunga nama-60% amanzi aphantsi komhlaba kunye nama-40% amanzi angaphezulu eVietnam angcoliseke ngokwamanqanaba ahlukeneyo, kunye nongcoliseko lwemicrobial kunye neekhemikhali yeyona nto ixhalabisayo. Kwiinkqubo zokubonelela ngamanzi, i-chlorine eshiyekileyo - njengenxalenye eseleyo yeklorini esebenzayo kwi-disinfection - idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lwamanzi. I-chlorine eshiyekileyo eyaneleyo iyasilela ukuphelisa ngokuqhubekayo iintsholongwane kwimibhobho, ngelixa amanqanaba aphezulu anokuvelisa i-carcinogenic disinfection byproducts. I-WHO icebisa ukuba kugcinwe intsalela yeklorini yoxinzelelo phakathi kwe-0.2-0.5mg/L emanzini okusela, ngelixa umgangatho we-QCVN waseVietnam 01:2009/BYT ufuna ubuncinci be-0.3mg/L kwiindawo zokuphela kwemibhobho.
Iziseko ezingundoqo zamanzi zaseVietnam zibonisa umahluko omkhulu wasezidolophini nasemaphandleni. Imimandla yasezidolophini efana neHanoi kunye neHo Chi Minh City ineenkqubo zobonelelo ezipheleleyo kodwa zijongene nemingeni esuka kwimibhobho egugayo kunye nokungcoliseka okwesibini. Malunga nama-25% abantu basemaphandleni abakafikeleli kumanzi okusela akhuselekileyo, bexhomekeke ikakhulu kumanzi angacocwanga kakuhle okanye angaphezulu kwamanzi. Olu phuhliso lungalinganiyo ludala iimfuno ezahlukeneyo kubuchwepheshe bokubeka iliso kwi-chlorine - imimandla yasezidolophini ifuna ukuchaneka okuphezulu, iinkqubo ze-intanethi ngexesha langempela ngelixa imimandla yasemaphandleni ibeka phambili ukuphumelela kweendleko kunye nokulula ukusebenza.
Iindlela zemveli zokubeka iliso zidibana nezithintelo ezininzi zokuphunyezwa eVietnam:
- Uhlalutyo lwebhubhoratri lufuna iiyure ezi-4-6 ngabasebenzi abaqeqeshiweyo
- Iisampulu ezenziwa ngesandla zinyanzelwa yijografi yaseVietnam emide kunye neenkqubo ezintsonkothileyo zemilambo
- Idatha ekhutshiweyo iyasilela ukubonelela ngemibono eqhubekayo yohlengahlengiso lwenkqubo
Le mida yabonakala ngokukodwa ngexesha likaxakeka njengesiganeko sokuvuza kweklorini ka-2023 kwipaki yoshishino kwiphondo laseDong Nai.
Itekhnoloji ye-sensor ye-chlorine eseleyo ibonelela ngezisombululo ezitsha zokujongwa kwamanzi eVietnam. Izinzwa zale mihla zisebenzisa imigaqo ye-electrochemical (i-polarography, i-voltage engaguqukiyo) okanye imigaqo yokubona (i-DPD colorimetry) ukulinganisa ngokuthe ngqo i-chlorine yasimahla kunye neyonke, ukuhambisa idatha yexesha lokwenyani ngoqhagamshelo olunentambo okanye olungenazingcingo. Xa kuthelekiswa neendlela zendabuko, le teknoloji inikezela ngokukhawuleza impendulo (<30 imizuzwana), ukuchaneka okuphezulu (± 0.02mg / L), kunye nokugcinwa okuphantsi - ngokukodwa ifaneleka kwimozulu yeTropiki yaseVietnam kunye neemfuno zokubeka iliso.
Amanyathelo aseVietnam “eSmart City” kunye nenkqubo yesizwe “yaManzi acocekileyo” abonelela ngenkxaso yomgaqo-nkqubo wokwamkelwa kwesivamvo seklorini. Ngowama-2024UPhuhliso lweShishini lokuPhuhlisa iKlorini ye-Chlorine eshiyekileyo kunye neNgxelo yoPhando loTyalo-maliibonisa izicwangciso zikarhulumente zokuphucula iinkqubo zokubeka iliso kwizixeko ezikhulu, ukubeka phambili izixhobo zokubeka esweni iklorini kwi-intanethi. Kwangaxeshanye, i-Ofisi yoMphathiswa wezeMpilo iye yandisa imfuneko yokubeka iliso rhoqo ngenyanga ukuya kwimihla ngemihla kwiindawo ezibalulekileyo, ngakumbi ukuqhuba imfuno yobuchwepheshe bexesha lokwenyani.
Itheyibhile: IMida yeChlorine eNshiyekileyo kwiMigangatho yoMgangatho waManzi waseVietnam
| Uhlobo lwaManzi | Umgangatho | Umlinganiselo weChlorine(mg/L) | Ukubeka iliso rhoqo |

Imarike ye-sensor ye-Vietnamese ibonisa ukuhlalisana kwamazwe ngamazwe, kunye ne-premium brands njenge-LAR yaseJamani kunye ne-HACH yaseMelika elawula amacandelo aphezulu ngelixa abavelisi baseTshayina abafana ne-Xi'an Yinrun (ERUN) kunye ne-Shenzhen AMT bafumana isabelo semarike ngamaxabiso akhuphisanayo. Ngokucacileyo, iinkampani zaseVietnam zingena kwimveliso yenzwa ngokusebenzisa intsebenziswano yetekhnoloji, efana ne-Hanoi-based firm's firm's low cost sensors ilingwe ngempumelelo kwiiprojekthi zamanzi zezikolo zasemaphandleni.
Ukwamkelwa kwendawo kujongene nemingeni emininzi yokuziqhelanisa:
- Ukufuma kweTropiki echaphazela izinto zombane
- I-turbidity ephezulu echaphazela ukuchaneka kwamehlo
- Ukubonelelwa ngombane okwethutyana kwiindawo ezisemaphandleni
Abavelisi baphendule ngokhuseleko lwe-IP68, ukucoca ngokuzenzekelayo, kunye nokhetho lwamandla elanga ukunyusa ukuthembeka kwiimeko ezifunwayo zaseVietnam.
Imigaqo yezobuGcisa kunye ne-Vietnam-Specific Adaptations
Izinzwa zeklorini ezishiyekileyo zisebenzisa iindlela ezintathu zokubona eziphambili eVietnam, nganye ilungele indawo ezahlukeneyo kunye nokusetyenziswa kwayo.
Izinzwa zePolarographic, ezibonakaliswe yi-ERUN-SZ1S-A-K6, zilawula ukufakela kukamasipala kunye nemizi-mveliso. Ezi zilinganisela ukwahluka kwangoku phakathi kwee-electrode ezisebenzayo kunye nereferensi (ngokuqhelekileyo iinkqubo ze-electrode zegolide), ezinikezela ngokuchaneka okuphezulu (± 1% FS) kunye nokuphendula ngokukhawuleza (<30s). Kwi-Ho Chi Minh City's Water Plant No.3, iziphumo ze-polarographic zibonise i-98% ukuhambelana nemigangatho ye-DPD yebhubhoratri. Iindlela ezidityanisiweyo zokucoca ezizenzekelayo (iinkqubo zebrashi) zandisa amaxesha olondolozo ukuya kwiinyanga ezi-2-3 – zibalulekile kumanzi atyebileyo eVietnam.
Izivamvo zamandla ombane rhoqo (umzekelo, iinkqubo ze-LAR) ziyagqwesa kusetyenziso oluntsonkothileyo lwamanzi amdaka. Ngokusebenzisa amandla azinzileyo kunye nomlinganiselo wesiphumo sangoku, babonisa ukuxhathisa okungaphezulu kophazamiseko ngokuchasene nesulfide kunye nemanganese-ibaluleke kakhulu kumanzi asezantsi eVietnam. Umzi-mveliso wamanzi amdaka weCan Tho AKIZ usebenzisa obu buchwepheshe ecaleni kweenkqubo ze-NitriTox ukugcina amanzi amdaka e-chlorine ku-0.5-1.0mg/L.
Izinzwa zombala we-Optical colorimetric ezifana neBlueview's ZS4 zibonelela ngebhajethi-ezazi iimfuno ezininzi zeeparamitha. Nangona icotha (2-5 imizuzu), umthamo wabo we-DPD-based multi-parameter (ngaxeshanye i-pH / turbidity) unciphisa iindleko zeenkonzo zephondo. Inkqubela phambili ye-Microfluidic icuthe ukusetyenziswa kwe-reagent nge-90%, yenza lula imithwalo yokulungisa.
