Semelo sa Tlhokomelo ea Boleng ba Metsi le Litlhoko tsa Taolo ea Chlorine Vietnam
E le naha ea Asia Boroa-bochabela e ntseng e hola ka potlako ebile e le litoropong, Vietnam e tobane le likhatello tse peli taolong ea mehloli ea metsi. Lipalo-palo li bonts'a hoo e ka bang 60% ea metsi a ka tlas'a lefatše le 40% ea metsi a holim'a Vietnam a silafalitsoe ho ea ka maemo a fapaneng, 'me tšilafalo ea likokoana-hloko le lik'hemik'hale e le tsona lintho tse tšoenyang haholo. Lits'ebetsong tsa phepelo ea metsi, chlorine e setseng - joalo ka karolo e setseng e sebetsang ea chlorine ho tsoa ho sebolaea likokoana-hloko - e bapala karolo ea bohlokoa ho netefatsa polokeho ea metsi. Masala a chlorine a sa lekaneng a hloleha ho tsoela pele ho felisa likokoana-hloko liphaepheng, ha maemo a feteletseng a ka hlahisa lihlahisoa tse bolaeang likokoana-hloko. WHO e khothalletsa ho boloka chlorine e setseng pakeng tsa 0.2-0.5mg/L metsing a nooang, ha maemo a Vietnam a QCVN 01:2009/BYT a hloka bonyane 0.3mg/L libakeng tsa lipeipi.
Lisebelisoa tsa metsi tsa Vietnam li bonts'a phapang e kholo ea litoropo le mahaeng. Libaka tsa litoropo tse kang Hanoi le Ho Chi Minh City li na le lits'ebetso tse felletseng tsa phepelo empa li tobane le mathata a liphaephe tsa botsofali le tšilafalo ea bobeli. Hoo e ka bang 25% ea baahi ba mahaeng ba ntse ba haelloa ke metsi a nooang a sireletsehileng, ba itšetlehile haholo ka metsi a sa hloekisoang hantle kapa a holim'a metsi. Tsoelo-pele ena e sa leka-lekaneng e baka litlhoko tse fapaneng tsa theknoloji ea ho shebella chlorine - libaka tsa litoropo li hloka mekhoa e nepahetseng e phahameng, ea nako ea sebele ea marang-rang ha libaka tsa mahaeng li etelletsa pele ho boloka litšenyehelo le boiketlo ba ts'ebetso.
Mekhoa ea setso ea ho beha leihlo e kopana le litšitiso tse ngata tsa ts'ebetsong Vietnam:
- Tlhahlobo ea laboratori e hloka lihora tse 4-6 ke basebetsi ba koetlisitsoeng
- Sampling ea letsoho e hatelloa ke sebaka se selelele sa Vietnam le litsamaiso tse rarahaneng tsa linōka
- Lintlha tse khaotsoeng li hloleha ho fana ka lintlha tse tsoelang pele bakeng sa litokiso tsa tšebetso
Mefokolo ena e ile ea totobala haholo nakong ea maemo a tšohanyetso joalo ka ketsahalo ea ho lutla ha chlorine ka 2023 serapeng sa boikhathollo sa indasteri seterekeng sa Dong Nai.
Theknoloji ea "Residual chlorine sensor" e fana ka tharollo e ncha bakeng sa tlhahlobo ea metsi ea Vietnam. Li-sensor tsa sejoale-joale li sebelisa melao-motheo ea electrochemical (polarography, voltage constant) kapa melao-motheo ea optical (DPD colorimetry) ho lekanya ka kotloloho chlorine ea mahala le e felletseng, e fetisa data ea nako ea nnete ka likhokahano tse nang le mehala kapa tse se nang mohala. Ha ho bapisoa le mekhoa ea setso, theknoloji ena e fana ka karabelo e potlakileng (<30 metsotsoana), ho nepahala ho phahameng (± 0.02mg/L), le tlhokomelo e tlaase - haholo-holo e loketseng boemo ba leholimo ba tropike ea Vietnam le litlhoko tsa tlhokomelo e arolelanoang.
Maiteko a Vietnam a "Smart City" le lenaneo la naha la "Metsi a Hloekileng" a fana ka ts'ehetso ea leano bakeng sa ho amoheloa ha sensor ea chlorine. Ka 2024Vietnam Residual Chlorine Analyzer Industry Development and Investment Research Reporte bonts'a merero ea mmuso ea ho ntlafatsa lits'ebetso tsa ho beha leihlo metseng e meholo, e etelletsa pele lisebelisoa tsa marang-rang tsa chlorine. Ka nako e ts'oanang, Lekala la Bophelo le ekelitse makhetlo a hlokahalang a ho beha leihlo ho tloha khoeli le khoeli ho isa ho letsatsi le leng le le leng libakeng tse mahlonoko, e leng ho eketsang tlhokeho ea theknoloji ea nako ea nnete.

Li-sensor tse setseng tsa chlorine li sebelisa mekhoa e meraro ea mantlha ea ho lemoha Vietnam, e 'ngoe le e 'ngoe e loketse tikoloho le lits'ebetso tse fapaneng.
Li-sensor tsa polarographic, tse bontšitsoeng ke ERUN-SZ1S-A-K6, li laola lisebelisoa tsa 'masepala le tsa indasteri. Tsena li lekanya phapang ea hajoale lipakeng tsa li-electrode tse sebetsang le tsa litšupiso (hangata litsamaiso tsa li-electrode tsa khauta), tse fanang ka ho nepahala ho phahameng (± 1% FS) le karabelo e potlakileng (<30s). Setsing sa Metsi sa Ho Chi Minh City No.3, liphetho tsa polarographic li bontšitse 98% ho lumellana le litekanyetso tsa laboratori tsa DPD. Mekhoa e kopaneng ea ho itlhoekisa (lits'ebetso tsa borashe) e eketsa nako ea ho lokisa ho fihla likhoeling tse 2-3 - e leng ea bohlokoa bakeng sa metsi a Vietnam a nang le algae e ngata.
Li-sensor tsa motlakase tse lulang li le teng (mohlala, LAR's system) li sebetsa hantle haholo lits'ebetsong tse rarahaneng tsa metsi a litšila. Ka ho sebelisa bokhoni bo sa fetoheng le ho lekanya sephetho sa hajoale, ba bonts'a khanyetso e phahameng ea tšitiso khahlano le sulfide le manganese - e bohlokoa haholo metsing a boima a tlhaho a Vietnam e ka boroa.
