Kugwiritsa Ntchito Moyenera ndi Kusanthula Zotsatira za Masensa Otsalira a Chlorine ku Vietnam

Mbiri ya Kuwunika Ubwino wa Madzi ndi Zosowa Zokhudza Kuwongolera Klorini ku Vietnam

Monga dziko lomwe likukula mofulumira m'mafakitale komanso m'mizinda ya Kum'mwera chakum'mawa kwa Asia, Vietnam ikukumana ndi mavuto awiri pa kayendetsedwe ka madzi. Ziwerengero zikusonyeza kuti pafupifupi 60% ya madzi apansi panthaka ndi 40% ya madzi a pamwamba panthaka ku Vietnam aipitsidwa mosiyanasiyana, ndipo kuipitsidwa kwa tizilombo toyambitsa matenda ndi mankhwala ndiko nkhawa yayikulu. Mu njira zoperekera madzi, chlorine yotsala - monga gawo lotsala la chlorine kuchokera ku kupha tizilombo toyambitsa matenda - imagwira ntchito yofunika kwambiri pakuonetsetsa kuti madzi ndi otetezeka. Kusakwanira kwa chlorine yotsala sikungathe kuchotsa tizilombo toyambitsa matenda m'mapaipi nthawi zonse, pomwe kuchuluka kwambiri kumatha kupanga zinthu zophera tizilombo toyambitsa matenda zomwe zimayambitsa khansa. Bungwe la WHO likulangiza kuti chlorine yotsala ikhale pakati pa 0.2-0.5mg/L m'madzi akumwa, pomwe muyezo wa QCVN 01:2009/BYT wa Vietnam umafuna osachepera 0.3mg/L kumapeto kwa mapaipi.

Zomangamanga zamadzi ku Vietnam zikuwonetsa kusiyana kwakukulu pakati pa mizinda ndi midzi. Madera a m'mizinda monga Hanoi ndi Ho Chi Minh City ali ndi njira zonse zoperekera madzi koma akukumana ndi mavuto ochokera ku mapaipi okalamba komanso kuipitsidwa kwachiwiri. Pafupifupi 25% ya anthu akumidzi akadalibe mwayi wopeza madzi abwino akumwa, makamaka chifukwa cha madzi osasamalidwa bwino kapena pamwamba pa madzi. Kukula kosagwirizana kumeneku kumapanga zofunikira zosiyanasiyana paukadaulo wowunikira chlorine - madera a m'mizinda amafunika njira zolondola kwambiri komanso zenizeni pa intaneti pomwe madera akumidzi amaika patsogolo njira zogwiritsira ntchito ndalama moyenera komanso zosavuta kugwiritsa ntchito.

Njira zowunikira zachikhalidwe zimakumana ndi zopinga zingapo pakukhazikitsa ku Vietnam:

• Kusanthula kwa labotale kumafuna maola 4-6 ndi ogwira ntchito ophunzitsidwa bwino.
• Kusankha zitsanzo pamanja kumayendetsedwa ndi malo ataliatali a Vietnam komanso njira zovuta zopezera mitsinje.
• Deta yolumikizidwa imalephera kupereka chidziwitso chokhazikika cha kusintha kwa njira

Zoletsa izi zidawonekera makamaka panthawi yadzidzidzi monga kutuluka kwa chlorine mu 2023 ku paki yamafakitale ku chigawo cha Dong Nai.

Ukadaulo wa masensa otsalira a chlorine umapereka njira zatsopano zowunikira madzi ku Vietnam. Masensa amakono amagwiritsa ntchito mfundo zamagetsi (polarography, constant voltage) kapena mfundo za kuwala (DPD colorimetry) kuti ayesere mwachindunji chlorine yaulere komanso yonse, kutumiza deta yeniyeni kudzera pa maulumikizidwe a waya kapena opanda zingwe. Poyerekeza ndi njira zachikhalidwe, ukadaulo uwu umapereka yankho mwachangu (

Ndondomeko za Vietnam za "Smart City" ndi pulogalamu ya dziko lonse ya "Clean Water" zimapereka chithandizo cha mfundo zogwiritsira ntchito masensa a chlorine.Lipoti la Kafukufuku wa Zachuma ndi Kugulitsa Zotsalira za ku Vietnamzikusonyeza kuti boma likukonzekera kukweza njira zowunikira m'mizinda ikuluikulu, ndikuyika patsogolo zida zowunikira za chlorine pa intaneti. Pakadali pano, Unduna wa Zaumoyo wawonjezera kuchuluka kwa kuwunika kofunikira kuyambira pamwezi mpaka tsiku lililonse pazifukwa zofunika kwambiri, zomwe zikuwonjezera kufunikira kwa ukadaulo weniweni.

Gome: Malire Otsalira a Chlorine mu Miyezo Yabwino ya Madzi ku Vietnam

Msika wa masensa aku Vietnam ukuwonetsa mgwirizano wapadziko lonse lapansi, ndi mitundu yapamwamba monga LAR yaku Germany ndi HACH yaku America ikulamulira magawo apamwamba pomwe opanga aku China monga Xi'an Yinrun (ERUN) ndi Shenzhen AMT akupeza gawo pamsika kudzera mumitengo yopikisana. Chodziwika bwino ndichakuti, makampani aku Vietnam akuyamba kupanga masensa kudzera mu mgwirizano waukadaulo, monga masensa otsika mtengo a kampani yaku Hanoi omwe adayesedwa bwino m'mapulojekiti amadzi akumidzi.

Kutengera ana m'deralo kukukumana ndi mavuto angapo okhudzana ndi kusintha kwa nyengo:

• Chinyezi cha m'madera otentha chomwe chimakhudza zamagetsi
• Kuthamanga kwakukulu komwe kumakhudza kulondola kwa kuwala
• Kupereka magetsi nthawi ndi nthawi m'madera akumidzi

Opanga ayankha ndi chitetezo cha IP68, kuyeretsa kokha, komanso njira zamagetsi a dzuwa kuti awonjezere kudalirika m'mikhalidwe yovuta ku Vietnam.

Mfundo Zaukadaulo ndi Kusintha Kwapadera kwa Vietnam

Masensa otsala a chlorine amagwiritsa ntchito njira zitatu zazikulu zodziwira ku Vietnam, iliyonse yoyenera malo ndi ntchito zosiyanasiyana.

Masensa a Polagraphic, omwe akuwonetsedwa ndi ERUN-SZ1S-A-K6, ndi omwe amalamulira ma electrode a m'matauni ndi mafakitale. Izi zimayesa kusiyana kwa ma electrode ogwirira ntchito ndi ma reference (nthawi zambiri ma electrode agolide), omwe amapereka kulondola kwambiri (±1%FS) ndi kuyankha mwachangu (<30s). Ku Ho Chi Minh City's Water Plant No.3, zotsatira za polagraphic zinawonetsa kusagwirizana kwa 98% ndi miyezo ya DPD ya labotale. Njira zoyeretsera zokha (ma burashi) zimawonjezera nthawi yokonza mpaka miyezi 2-3 - zofunika kwambiri m'madzi okhala ndi algae ambiri ku Vietnam.

Ma sensor amagetsi okhazikika (monga machitidwe a LAR) amagwira ntchito bwino kwambiri pakugwiritsa ntchito madzi otayira movutikira. Pogwiritsa ntchito mphamvu yokhazikika komanso kuyesa mphamvu yamagetsi yomwe imabwera chifukwa cha izi, amasonyeza kukana kwakukulu kwa sulfides ndi manganese - makamaka kofunikira m'madzi olemera a kum'mwera kwa Vietnam. Fakitale yamadzi otayira ya Can Tho AKIZ imagwiritsa ntchito ukadaulo uwu pamodzi ndi machitidwe a NitriTox kuti isunge chlorine yotuluka pa 0.5-1.0mg/L.

Masensa owunikira a colorimetric monga Blueview's ZS4 amakwaniritsa zosowa za ma multiparameter omwe amaganizira bajeti. Ngakhale kuti ndi ochedwa (mphindi 2-5), mphamvu yawo ya ma multiparameter yochokera ku DPD (pH/turbidity nthawi imodzi) imachepetsa ndalama zogulira magetsi m'zigawo. Kupita patsogolo kwa microfluidic kwachepetsa kugwiritsa ntchito ma reagent ndi 90%, zomwe zachepetsa mavuto okonza.

Tikhozanso kupereka njira zosiyanasiyana zothetsera mavutowa

1. Chida chogwiritsira ntchito m'manja cha ubwino wa madzi okhala ndi magawo ambiri

2. Dongosolo loyandama la Buoy la ubwino wa madzi okhala ndi magawo ambiri

3. Burashi yoyeretsera yokha ya sensa yamadzi yokhala ndi magawo ambiri

4. Seti yonse ya ma seva ndi mapulogalamu opanda zingwe, imathandizira RS485 GPRS /4g/WIFI/LORA/LORAWAN
