Mbiri Yakuwunika Ubwino wa Madzi ndi Zofunikira Zowongolera Chlorine ku Vietnam
Monga dziko lomwe likukula mwachangu komanso kutukuka kwamizinda yaku Southeast Asia, Vietnam ikukumana ndi zovuta zapawiri pa kayendetsedwe ka madzi. Ziwerengero zikuwonetsa pafupifupi 60% yamadzi apansi panthaka ndi 40% yamadzi akumtunda ku Vietnam adayipitsidwa mosiyanasiyana, kuipitsidwa ndi tizilombo tating'onoting'ono ndi mankhwala ndizomwe zimadetsa nkhawa kwambiri. M'machitidwe operekera madzi, chlorine yotsalira - monga chigawo chotsalira cha klorini kuchokera ku mankhwala ophera tizilombo - imagwira ntchito yofunika kwambiri poonetsetsa kuti madzi ali otetezeka. Kusakwanira kotsalira kwa klorini kumalephera kuthetsa mosalekeza tizilombo toyambitsa matenda m'mapaipi, pomwe milingo yochulukirapo imatha kutulutsa mankhwala ophera tizilombo toyambitsa matenda. WHO imalimbikitsa kuti chlorine ikhale yotsalira pakati pa 0.2-0.5mg/L m'madzi akumwa, pamene mulingo wa QCVN 01:2009/BYT waku Vietnam umafunika kuchepera 0.3mg/L kumapeto kwa mapaipi.
Zomangamanga zamadzi ku Vietnam zikuwonetsa kusiyana kwakukulu kumatauni ndi akumidzi. Madera akumatauni ngati Hanoi ndi Ho Chi Minh City ali ndi njira zonse zoperekera zinthu koma amakumana ndi zovuta zamapaipi okalamba komanso kuipitsidwa kwachiwiri. Pafupifupi 25% ya anthu akumidzi alibe mwayi wopeza madzi abwino akumwa, kudalira kwambiri madzi osatetezedwa bwino kapena pamwamba. Chitukuko chosagwirizanachi chimapanga zofunikira zosiyanasiyana zaumisiri wowunika chlorine - madera akumidzi amafunikira njira zolondola kwambiri, zenizeni zenizeni zapa intaneti pomwe madera akumidzi amaika patsogolo kukwera mtengo komanso kusavuta kugwira ntchito.
Njira zowunikira zachikhalidwe zimakumana ndi zolepheretsa zingapo ku Vietnam:
- Kusanthula kwa labotale kumafuna maola 4-6 ndi ogwira ntchito ophunzitsidwa bwino
- Zitsanzo zapamanja zimatsatiridwa ndi madera akutali a Vietnam komanso mitsinje yovuta
- Deta yolumikizidwa imalephera kupereka zidziwitso mosalekeza pakusintha kwadongosolo
Zolepheretsa izi zidawonekera makamaka pakachitika ngozi ngati 2023 kutayikira kwa chlorine papaki yamafakitale m'chigawo cha Dong Nai.
Ukadaulo wotsalira wa chlorine sensor umapereka njira zatsopano zowunikira madzi aku Vietnam. Masensa amakono amagwiritsa ntchito mfundo za electrochemical (polarography, voltage constant) kapena optical principles (DPD colorimetry) kuti athe kuyeza mwachindunji chlorine yaulere komanso yokwanira, kutumiza deta yeniyeni kudzera pamalumikizidwe a waya kapena opanda zingwe. Poyerekeza ndi njira zachikhalidwe, ukadaulo uwu umapereka mayankho mwachangu (<30 masekondi), kulondola kwapamwamba (± 0.02mg/L), komanso kukonza pang'ono - makamaka koyenera nyengo yotentha ya Vietnam komanso zosowa zowunikira.
Zoyeserera zaku Vietnam za "Smart City" ndi pulogalamu yapadziko lonse ya "Madzi Oyera" zimapereka chithandizo chothandizira kutengera kachipangizo ka chlorine. The 2024Vietnam Residual Chlorine Analyzer Industry Development ndi Investment Research Reportikuwonetsa mapulani aboma okweza njira zowunikira m'mizinda ikuluikulu, ndikuyika zida zowunikira pa intaneti za chlorine. Momwemonso, Unduna wa Zaumoyo wawonjezera kuwunika kofunikira kuyambira mwezi uliwonse mpaka tsiku ndi tsiku pamalo ovuta, kupititsa patsogolo kufunikira kwaukadaulo wanthawi yeniyeni.
Tebulo: Malire Otsalira a Chlorine mu Makhalidwe Abwino a Madzi aku Vietnam
| Mtundu wa Madzi | Standard | Chlorine Limit(mg/L) | Kuwunika pafupipafupi |
|---|---|---|---|
| Madzi Akumwa a Municipal | QCVN 01:2009/BYT | ≥0.3 (mapeto) | Tsiku ndi tsiku (zofunikira) |
| Madzi a Botolo | QCVN 6-1:2010/BYT | ≤0.3 | Pa gulu |
| Dziwe losambirira | QCVN 02:2009/BYT | 1.0-3.0 | Maola awiri aliwonse |
| Madzi a Chipatala | QCVN 28:2010/BTNMT | ≤1.0 | Zopitilira |
| Kuzizira kwa Industrial | Miyezo ya Makampani | 0.5-2.0 | Zotengera ndondomeko |
Msika wa masensa aku Vietnam ukuwonetsa kukhalirana kwapadziko lonse lapansi, okhala ndi mitundu yoyambira ngati LAR yaku Germany ndi HACH yaku America yomwe imayang'anira magawo apamwamba pomwe opanga aku China monga Xi'an Yinrun (ERUN) ndi Shenzhen AMT amapeza msika kudzera pamitengo yampikisano. Zachidziwikire, makampani aku Vietnamese akulowa muzopanga zamasensa kudzera mumgwirizano waukadaulo, monga ma sensa otsika mtengo a kampani ya Hanoi omwe amayesedwa bwino pamapulojekiti amadzi akumidzi akumidzi.
Kukonzekera kotereku kumakumana ndi zovuta zingapo:
- Chinyezi chotentha chomwe chimakhudza zamagetsi
- Kuchuluka kwa turbidity kumakhudza kulondola kwa mawonekedwe
- Kupereka magetsi kwapang'onopang'ono kumidzi
Opanga ayankha ndi chitetezo cha IP68, kuyeretsa zokha, komanso njira zamagetsi adzuwa kuti apititse patsogolo kudalirika kwazomwe zikuchitika ku Vietnam.
Mfundo Zaukadaulo ndi Kusintha Kwapadera kwa Vietnam
Masensa otsalira a klorini amagwiritsa ntchito njira zitatu zodziwira ku Vietnam, iliyonse yoyenerera malo osiyanasiyana komanso momwe angagwiritsire ntchito.
Masensa a polarographic, owonetsedwa ndi ERUN-SZ1S-A-K6, amalamulira ma municipalities ndi mafakitale. Izi zimayezera kusiyanasiyana komwe kulipo pakati pa ma elekitirodi ogwirira ntchito ndi ofotokozera (makamaka makina amagetsi agolide), omwe amapereka kulondola kwambiri (± 1% FS) ndikuyankha mwachangu (<30s). Ku Ho Chi Minh City's Water Plant No.3, zotsatira za polarographic zinawonetsa 98% kusagwirizana ndi miyezo ya labotale ya DPD. Njira zoyeretsera zodzitchinjiriza zokha (maburashi) zimakulitsa nthawi yokonza mpaka miyezi 2-3 - ndizofunika kwambiri pamadzi odzaza ndere ku Vietnam.
Masensa amagetsi osasunthika (mwachitsanzo, machitidwe a LAR) amapambana pakugwiritsa ntchito madzi oyipa ovuta. Pogwiritsa ntchito mphamvu zokhazikika komanso kuyeza zomwe zachitika pano, zikuwonetsa kukana kusokoneza sulfide ndi manganese - zomwe zili zofunika kwambiri kumadzi akumwera kwa Vietnam. Chomera chamadzi am'madzi am'mafakitale cha Can Tho AKIZ chimagwiritsa ntchito ukadaulowu limodzi ndi makina a NitriTox kuti asunge chlorine yotayirira pa 0.5-1.0mg/L.
Ma sensor a colorimetric owoneka ngati Blueview's ZS4 amapereka zosowa zamagawo ambiri a bajeti. Ngakhale pang'onopang'ono (mphindi 2-5), mphamvu zawo za DPD-based multi-parameter (panthawi yomweyo pH / turbidity) zimachepetsa ndalama zothandizira zigawo. Kupita patsogolo kwa Microfluidic kwachepetsa kugwiritsidwa ntchito kwa reagent ndi 90%, ndikuchepetsa zovuta zosamalira.
Titha kuperekanso mayankho osiyanasiyana
1. M'manja mita kwa Mipikisano parameter madzi khalidwe
2. Dongosolo la Buoy loyandama lamtundu wamadzi wamitundu yambiri
3. Burashi yotsuka yokha yamadzi ambiri amadzimadzi
4. Seti yathunthu ya ma seva ndi pulogalamu yopanda zingwe, imathandizira RS485 GPRS / 4g/WIFI/LORA/LORAWAN
