Isizinda Sokuqapha Ikhwalithi Yamanzi Nezidingo Zokulawula I-Chlorine eVietnam
Njengezwe elikhula ngokushesha kwezimboni futhi elikhula emadolobheni eNingizimu-mpumalanga ye-Asia, iVietnam ibhekene nezingcindezi ezimbili ekuphathweni kwemithombo yamanzi. Izibalo zibonisa ukuthi cishe u-60% wamanzi angaphansi komhlaba kanye no-40% wamanzi angaphezulu eVietnam angcoliswe ngamazinga ahlukahlukene, kanti ukungcola kwamagciwane namakhemikhali kuyizinto eziyinhloko ezikhathazayo. Ezinhlelweni zokuhlinzeka ngamanzi, i-chlorine esele – njengengxenye ye-chlorine esebenzayo esele evela ekuhlanzeni – idlala indima ebalulekile ekuqinisekiseni ukuphepha kwamanzi. I-chlorine esele enganele yehluleka ukuqeda njalo amagciwane emapayipini, kuyilapho amazinga aphezulu angakhiqiza imikhiqizo yokubulala amagciwane ebangela umdlavuza. I-WHO incoma ukugcina amazinga e-chlorine esele ephakathi kuka-0.2-0.5mg/L emanzini okuphuza, kuyilapho indinganiso ye-QCVN 01:2009/BYT yaseVietnam idinga okungenani u-0.3mg/L ezindaweni zokugcina zamapayipi.
Ingqalasizinda yamanzi yaseVietnam ibonisa ukungalingani okukhulu phakathi kwasemadolobheni nasemaphandleni. Izindawo zasemadolobheni njengeHanoi neHo Chi Minh City zinezinhlelo zokuphakelwa eziphelele kodwa zibhekene nezinselelo ezivela kumapayipi agugile kanye nokungcola kwesibili. Cishe ama-25% abantu basemakhaya basantula ukufinyelela emanzini okuphuza aphephile, bethembele kakhulu emanzini angasetshenziswanga kahle noma angaphezulu. Lokhu kuthuthukiswa okungalingani kudala izidingo ezahlukahlukene zobuchwepheshe bokuqapha i-chlorine - izindawo zasemadolobheni zidinga izinhlelo eziku-inthanethi ezinembile kakhulu, zesikhathi sangempela kuyilapho izifunda zasemakhaya zibeka phambili ukusebenza kahle kwezindleko kanye nokulula kokusebenza.
Izindlela zokuqapha zendabuko zibhekana nezithiyo eziningi zokusebenzisa eVietnam:
- Ukuhlaziywa kwelabhorethri kudinga amahora angu-4-6 ngabasebenzi abaqeqeshiwe
- Ukuthatha amasampula ngesandla kunqunywa yisimo sendawo eside saseVietnam kanye nezinhlelo zemifula eziyinkimbinkimbi
- Idatha enqanyuliwe yehluleka ukunikeza ulwazi oluqhubekayo lokulungiswa kwenqubo
Lezi mikhawulo zabonakala kakhulu ngesikhathi sezimo eziphuthumayo njengesigameko sokuvuza kwe-chlorine ngo-2023 epaki yezimboni esifundazweni saseDong Nai.
Ubuchwepheshe bezinzwa ze-chlorine ezisele bunikeza izixazululo ezintsha zokuqapha amanzi eVietnam. Izinzwa zesimanje zisebenzisa kakhulu izimiso ze-electrochemical (i-polarography, i-voltage engaguquki) noma izimiso ze-optical (i-DPD colorimetry) ukukala ngqo i-chlorine yamahhala nephelele, zidlulisa idatha yesikhathi sangempela ngokuxhumeka okunezintambo noma okungenantambo. Uma kuqhathaniswa nezindlela zendabuko, lobu buchwepheshe bunikeza impendulo esheshayo ( Izinhlelo ze-“Smart City” zaseVietnam kanye nohlelo lukazwelonke lwe-“Clean Water” zinikeza ukwesekwa kwenqubomgomo yokusetshenziswa kwezinzwa ze-chlorine.Umbiko Wocwaningo Lwezokuthuthukiswa Kwemboni Nokutshalwa Kwezimali Lwe-Vietnam Residual Chlorine Analyzerkukhombisa ukuthi uhulumeni uhlela ukuthuthukisa izinhlelo zokuqapha emadolobheni amakhulu, ebeka phambili imishini yokuqapha i-chlorine eku-inthanethi. Ngesikhathi esifanayo, uMnyango Wezempilo ukhuphule imvamisa yokuqapha edingekayo kusukela ngenyanga kuya kwansuku zonke ezindaweni ezibalulekile, okwenza kube nesidingo esikhulu sobuchwepheshe besikhathi sangempela. Ithebula: Imikhawulo Ye-Chlorine Esele Ezindinganisweni Zekhwalithi Yamanzi zaseVietnam Imakethe yezinzwa zaseVietnam ikhombisa ukuhlalisana kwamazwe ngamazwe, ngemikhiqizo ephezulu efana ne-LAR yaseJalimane kanye ne-HACH yaseMelika ebusa izingxenye eziphezulu kuyilapho abakhiqizi baseShayina abanjengo-Xi'an Yinrun (ERUN) kanye ne-Shenzhen AMT bethola isabelo semakethe ngamanani ancintisanayo. Okuphawulekayo ukuthi izinkampani zaseVietnam zingena ekukhiqizweni kwezinzwa ngokubambisana kwezobuchwepheshe, njengezinzwa ezishibhile zenkampani eseHanoi ezivivinywe ngempumelelo kumaphrojekthi amanzi ezikoleni zasemakhaya. Ukwamukelwa kwezingane endaweni kubhekene nezinselele eziningana zokuzivumelanisa nezimo: Abakhiqizi baphendule ngokuvikela i-IP68, ukuhlanza okuzenzakalelayo, kanye nezinketho zamandla elanga ukuze bathuthukise ukuthembeka ezimweni ezicindezelayo zaseVietnam. Izinzwa ze-chlorine ezisele zisebenzisa izindlela ezintathu eziyinhloko zokuthola eVietnam, ngayinye ifanele izindawo ezahlukene kanye nezinhlelo zokusebenza. Izinzwa ze-polarographic, eziboniswe yi-ERUN-SZ1S-A-K6, zilawula ukufakwa kukamasipala kanye nezimboni. Lezi zilinganisa ukwehluka kwamanje phakathi kwama-electrode okusebenza kanye nama-reference (ngokuvamile izinhlelo ze-electrode zegolide), ezinikeza ukunemba okuphezulu (±1%FS) kanye nokuphendula okusheshayo (<30s). E-Ho Chi Minh City's Water Plant No.3, imiphumela ye-polarographic ibonise ukuhambisana okungu-98% nezindinganiso ze-DPD zelebhu. Izindlela zokuhlanza ezizenzakalelayo ezihlanganisiwe (izinhlelo zamabhulashi) zandisa izikhawu zokulungisa zibe izinyanga ezingu-2-3 - ezibalulekile emanzini aseVietnam agcwele ulwelwe. Izinzwa ze-voltage ezihlala zisebenza (isb., izinhlelo ze-LAR) zisebenza kahle kakhulu ekusetshenzisweni kwamanzi amdaka ayinkimbinkimbi. Ngokusebenzisa amandla angaguquki kanye nokulinganisa ugesi ophumelayo, zibonisa ukumelana okuphezulu kokuphazamiseka ngokumelene nama-sulfide kanye ne-manganese - okubaluleke kakhulu emanzini aseningizimu yeVietnam anzima ngokwezinto eziphilayo. Isitshalo samanzi amdaka sezimboni i-Can Tho AKIZ sisebenzisa lobu buchwepheshe kanye nezinhlelo ze-NitriTox ukugcina i-chlorine engcolile ku-0.5-1.0mg/L. Izinzwa ze-optical colorimetric ezifana ne-Blueview's ZS4 zifeza izidingo zamapharamitha amaningi ezinqunyelwe isabelomali. Nakuba zihamba kancane (imizuzu emi-2-5), umthamo wazo wamapharamitha amaningi asekelwe ku-DPD (i-pH/turbidity ngesikhathi esisodwa) unciphisa izindleko zezinsiza zesifundazwe. Ukuthuthukiswa kwe-microfluidic kunciphise ukusetshenziswa kwe-reagent ngo-90%, okwenza kwaba lula ukugcinwa kwemithwalo. Singaphinde sinikeze izixazululo ezahlukahlukene ze 1. Imitha ephathwayo yekhwalithi yamanzi enamapharamitha amaningi 2. Uhlelo lwe-Floating Buoy lwekhwalithi yamanzi enamapharamitha amaningi 3. Ibhulashi lokuhlanza elizenzakalelayo lenzwa yamanzi enamapharamitha amaningi 4.
