Ikoreshwa mu buryo bufatika n'isesengura ry'ingaruka z'ibice bipima Chlorine muri Vietnam

Amasomo y'igenzura ry'ubuziranenge bw'amazi n'ibikenewe mu kugenzura chlorine muri Vietnam

Kubera ko igihugu gikomeje gutera imbere mu nganda no mu mijyi mu majyepfo y'uburasirazuba bwa Aziya, Vietnam ihura n'ibibazo bibiri ku micungire y'umutungo kamere w'amazi. Imibare igaragaza ko hafi 60% by'amazi yo munsi y'ubutaka na 40% by'amazi yo hejuru muri Vietnam byanduye ku rugero rutandukanye, aho ihumana rya mikorobe n'ibinyabutabire ari byo byihutirwa. Mu miyoboro y'amazi, chlorine isigaye - nk'igice cya chlorine isigaye iva mu kwica udukoko - igira uruhare runini mu kurinda umutekano w'amazi. Chlorine idafite ihagije idashobora gukuraho indwara mu miyoboro, mu gihe urugero rurenze urugero rushobora gutera indwara ziterwa na kanseri. OMS isaba ko chlorine isigaye igumana hagati ya 0.2-0.5mg/L mu mazi yo kunywa, mu gihe igipimo cya QCVN 01:2009/BYT cya Vietnam gisaba nibura 0.3mg/L ku mpera z'imiyoboro.

Ibikorwa remezo by'amazi byo muri Vietnam bigaragaza itandukaniro rikomeye hagati y'imijyi n'ibyaro. Uduce tw'imijyi nka Hanoi na Ho Chi Minh City dufite uburyo bwuzuye bwo gutanga amazi ariko duhura n'imbogamizi zikomoka ku miyoboro ishaje ndetse n'umwanda wa kabiri. Hafi 25% by'abaturage bo mu cyaro baracyabura amazi meza yo kunywa, ahanini bishingikiriza ku mazi meza cyangwa amazi yo hejuru adasukuwe neza. Iri terambere ritaringaniye rituma habaho ikoranabuhanga rijyanye no kugenzura chlorine - uturere tw'imijyi dukeneye uburyo bwo gukoresha interineti neza kandi bugezweho mu gihe uturere tw'icyaro dushyira imbere uburyo bwo gukoresha amafaranga make no koroshya imikorere.

Uburyo gakondo bwo gukurikirana buhura n'imbogamizi nyinshi mu ishyirwa mu bikorwa muri Vietnam:

• Isesengura rya laboratwari risaba amasaha 4-6 n'abakozi bahuguwe
• Gufata ingero z'amazi hakoreshejwe intoki bigengwa n'imiterere miremire ya Vietnam n'imigezi igoye
• Amakuru adahujwe yananiwe gutanga ibitekerezo bihoraho ku bijyanye no guhindura inzira

Izi mbogamizi zagaragaye cyane cyane mu bihe byihutirwa nko mu 2023 habaye ikibazo cya chlorine yavuye muri pariki y’inganda mu ntara ya Dong Nai.

Ikoranabuhanga rya "residual chlorine sensor" ritanga ibisubizo bishya byo kugenzura amazi muri Vietnam. Ibyuma bigezweho bikoresha cyane cyane amahame ya electrochemical (polarography, constant voltage) cyangwa amahame ya optique (DPD colorimetry) kugira ngo bipime chlorine yigenga kandi yuzuye, byohereze amakuru mu gihe nyacyo binyuze mu miyoboro y'insinga cyangwa idafite insinga. Ugereranyije n'uburyo busanzwe, iri koranabuhanga ritanga igisubizo cyihuse (

Gahunda za Vietnam zo "Umujyi Usobanutse" na gahunda y'igihugu "Amazi Asukuye" bitanga inkunga ya politiki yo gukoresha uburyo bwo gupima chlorine.Raporo y'ubushakashatsi ku iterambere ry'inganda n'ishoramari ku bisigazwa bya Chlorine muri Vietnambigaragaza ko guverinoma ifite gahunda yo kuvugurura uburyo bwo kugenzura mu mijyi minini, ishyira imbere ibikoresho byo kugenzura chlorine kuri interineti. Muri icyo gihe, Minisiteri y'Ubuzima yongereye inshuro zisabwa zo kugenzura kuva ku kwezi kugeza ku munsi mu bihe bikomeye, ibyo bikaba birushaho gutuma ikoranabuhanga rikoreshwa mu buryo bufatika rirushaho gukenerwa.

Imbonerahamwe: Imipaka ya Chlorine isigaye mu bipimo ngenderwaho by'ubuziranenge bw'amazi muri Vietnam

Isoko ry’ibikoresho byo mu bwoko bwa “sensor” muri Vietnam rigaragaza ko rifitanye isano mpuzamahanga n’ibihugu bitandukanye, aho ibigo by’indashyikirwa nka LAR yo mu Budage na HACH yo muri Amerika byiganje mu byiciro byo ku rwego rwo hejuru mu gihe inganda zo mu Bushinwa nka Xi'an Yinrun (ERUN) na Shenzhen AMT zibona isoko binyuze mu ibiciro bishimishije. Ikigaragara ni uko amasosiyete yo muri Vietnam yinjira mu nganda zikora ibikoresho byo mu bwoko bwa “sensor” binyuze mu bufatanye mu ikoranabuhanga, nk'aho ibikoresho byo mu bwoko bwa “sensor” bihendutse by’ikigo cyo muri Hanoi byageragejwe neza mu mishinga y’amazi yo mu cyaro.

Gukoresha abana mu nzego z'ibanze bihura n'imbogamizi nyinshi zo guhangana n'imihindagurikire y'ikirere:

• Ubushuhe bw'ikirere bugira ingaruka ku bikoresho by'ikoranabuhanga
• Ubushyuhe bwinshi bugira ingaruka ku buryo butaziguye bw'urumuri
• Ingufu z'amashanyarazi zitangwa rimwe na rimwe mu byaro

Abakora ibikoresho byasubije uburinzi bwa IP68, isuku yikora, n'ingufu zikomoka ku mirasire y'izuba kugira ngo bongere ubwizerwe mu bihe bigoye byo muri Vietnam.

Amahame ya tekiniki n'uburyo bwo guhindura ibintu mu buryo bwihariye muri Vietnam

Utwuma dukoresha chlorine dusigaye dukoresha uburyo butatu bw'ibanze bwo gupima muri Vietnam, buri bumwe bukwiriye ibidukikije bitandukanye n'uburyo bukoreshwa.

Ibyuma bipima ikirere, byagaragajwe na ERUN-SZ1S-A-K6, byiganje mu nganda n’ibigo by’umujyi. Ibi bipima itandukaniro riri hagati y’amashanyarazi akoreshwa n’ay’inyongera (ubusanzwe ni sisitemu za zahabu zikoresha amashanyarazi), bitanga ubuziranenge bwo hejuru (± 1% FS) n’uburyo bwo gusubiza vuba (< 30s). Mu ruganda rw’amazi rwa Ho Chi Minh City No.3, ibyavuye mu bushakashatsi ku kirere byagaragaje ko 98% by’ubuziranenge bw’ibipimo bya DPD muri laboratwari. Uburyo bwo gusukura bwikora (uburyo bwo gukaraba) bwongera igihe cyo kubungabunga kugeza ku mezi 2-3 - ingenzi ku mazi akungahaye ku bimera byo muri Vietnam.

Utwuma tw’amashanyarazi duhoraho (urugero, sisitemu za LAR) turakora neza mu mikoreshereze y’amazi mabi. Mu gukoresha ubushobozi buhoraho no gupima umuriro uturuka kuri yo, bigaragaza ko sulfide na manganese ari ingenzi cyane mu mazi akomeye yo mu majyepfo ya Vietnam. Uruganda rw’amazi mabi rwo mu nganda rwa Can Tho AKIZ rukoresha ubu buryo hamwe na sisitemu za NitriTox kugira ngo rugumane chlorine y’amazi mabi iri kuri 0.5-1.0mg/L.

Utwuma dupima imiterere y'amabara nka Blueview's ZS4 dufasha mu gukenera ibintu byinshi mu buryo busanzwe. Nubwo bitinda (iminota 2-5), ubushobozi bwabyo bwo gukoresha ibintu byinshi mu buryo bwa DPD (pH/turbidity icyarimwe) bugabanya ikiguzi cy'ibigo by'imari n'amashanyarazi byo mu ntara. Iterambere rya microfluidic ryagabanyije ikoreshwa rya reagent ku kigero cya 90%, bigabanya imitwaro yo kubungabunga.

Dushobora kandi gutanga ibisubizo bitandukanye kuri

1. Igipimo gifata mu ntoki cy'ubwiza bw'amazi gifite ibipimo byinshi

2. Sisitemu yo gukamura amazi mu mazi ikoresha imiterere myinshi

3. Uburoso bwo gusukura bwikora ku buryo bwikora ku buryo bworoshye bw'amazi bukoresha parameter nyinshi

4. Seti yuzuye ya seriveri na porogaramu ya module idafite umugozi, ishyigikira RS485 GPRS /4g/WIFI/LORA/LORAWAN
