Nhoroondo yeKutarisa Hunhu hweMvura uye Zvinodiwa zveKudzora Chlorine muVietnam
Senyika iri kukura nekukurumidza uye iri kukura mumaguta kuSoutheast Asia, Vietnam inotarisana nematambudziko maviri pakutarisira zviwanikwa zvemvura. Nhamba dzinoratidza kuti inenge 60% yemvura yepasi pevhu uye 40% yemvura yepamusoro muVietnam yakasvibiswa kusvika padanho rakasiyana, kusvibiswa kwehutachiona nemakemikari kuri iko kunonyanya kukonzera matambudziko. Munzvimbo dzemvura, chlorine yakasara - sechikamu chechlorine chinoshanda kubva mukuuraya utachiona - inoita basa rakakosha mukuona kuti mvura yakachengeteka. Kusakwana kwechlorine yakasara hakugone kubvisa utachiona mumapaipi, nepo huwandu hwakawanda hunogona kukonzera hutachiona hunokonzera kenza. WHO inokurudzira kuchengetedza huwandu hwechlorine yakasara pakati pe0.2-0.5mg/L mumvura yekunwa, nepo QCVN 01:2009/BYT standard yeVietnam ichida 0.3mg/L pamagumo emapaipi.
Zvivakwa zvemvura zvemuVietnam zvinoratidza kusawirirana kukuru pakati pemaguta nemaruwa. Maguta akaita seHanoi neHo Chi Minh City ane masisitimu akakwana ekugovera asi anotarisana nematambudziko kubva kumapaipi ekare uye kusvibiswa kwechipiri. Vanhu vanosvika 25% vekumaruwa vachiri kushaya mvura yekunwa yakachengeteka, vachinyanya kuvimba nemvura isina kubatwa zvakanaka kana mvura yepamusoro. Kukura uku kusina kuenzana kunoita kuti pave nezvinodiwa zvakasiyana-siyana zvekuongorora chlorine - maguta anoda masisitimu epamhepo akanyatsojeka, panguva chaiyo ukuwo matunhu ekumaruwa achikoshesa kushandiswa kwemari uye nyore kushandisa.
Nzira dzekare dzekutarisa dzinosangana nezvipingamupinyi zvakawanda zvekushandisa muVietnam:
- Kuongororwa kwerabhoritari kunoda maawa mana kusvika matanhatu nevashandi vakadzidziswa
- Kutora sampuro nemaoko kunodzorwa nenharaunda yakareba yeVietnam uye masisitimu erwizi akaomarara.
- Data rakabviswa harina kupa ruzivo rwakawanda rwekugadzirisa maitiro
Zvipingamupinyi izvi zvakava pachena zvakanyanya panguva dzenjodzi dzakadai sekudonha kwechlorine muna 2023 panzvimbo yemaindasitiri mudunhu reDong Nai.
Tekinoroji yezvinoona chlorine yasara inopa mhinduro itsva dzekutarisa mvura muVietnam. Masensa emazuva ano anonyanya kushandisa misimboti ye electrochemical (polarography, constant voltage) kana misimboti ye optical (DPD colorimetry) kuyera zvakananga chlorine yakasununguka uye yakazara, ichitumira data renguva chaiyo kuburikidza nekubatanidza newaya kana waya. Kana tichienzanisa nenzira dzechinyakare, tekinoroji iyi inopa mhinduro nekukurumidza (<30 seconds), kunyatsorurama kwakanyanya (±0.02mg/L), uye kugadzirisa kushoma - kwakakodzera mamiriro ekunze emuVietnam uye zvinodiwa zvekutarisa zvakaganhurirwa.
Zvirongwa zveVietnam zve "Smart City" nechirongwa chenyika che "Clean Water" zvinopa rutsigiro rwemutemo wekushandiswa kwemasensa e chlorine.Mushumo weKutsvagisa kweIndasitiri neKudyara Mari weVietnam Residual Chlorine Analyzerzvinoratidza kuti hurumende inoronga kuvandudza masisitimu ekutarisa mumaguta makuru, ichiisa pamberi michina yekutarisa chlorine online. Panguva imwe chete, Bazi reHutano rakawedzera huwandu hwekutarisa hunodiwa kubva pamwedzi kusvika pazuva nezuva panguva dzakakosha, zvichiwedzera kudiwa kwetekinoroji inoshanda panguva chaiyo.
Tafura: Miganhu yeChlorine Yasara muMitemo Yehunhu hweMvura yeVietnam
| Rudzi rweMvura | Zvakajairika | Muganho weChlorine (mg/L) | Kuongororwa Kuwanda |

Musika wemasensa ekuVietnam unoratidza kugara pamwe chete kwenyika dzakasiyana-siyana, nemabhurandi epamusoro akadai seLAR yekuGermany neHACH yekuAmerica achitonga zvikamu zvepamusoro nepo vagadziri vekuChina vakaita seXi'an Yinrun (ERUN) neShenzhen AMT vachiwana mugove wemusika kuburikidza nemitengo inokwikwidzana. Zvinoshamisa kuti, makambani ekuVietnam ari kupinda mukugadzira masensa kuburikidza nekudyidzana kwetekinoroji, senge masensa ekambani iri muHanoi akaedzwa zvinobudirira mumapurojekiti emvura ezvikoro zvekumaruwa.
Kutora vana vemunharaunda kunosangana nematambudziko akasiyana-siyana ekugadzirisa matambudziko:
- Hunyoro hwenzvimbo dzinopisa hunokanganisa midziyo yemagetsi
- Kusviba kwakanyanya kunokanganisa kunyatsojeka kwemaziso
- Kuwanikwa kwemagetsi nguva nenguva munzvimbo dzekumaruwa
Vagadziri vakapindura nedziviriro yeIP68, kuchenesa otomatiki, uye sarudzo dzesimba rezuva kuti vawedzere kuvimbika mumamiriro ezvinhu akaomarara eVietnam.
Nheyo dzeUnyanzvi uye Kugadziriswa Kwakanangana neVietnam
Masensa echlorine akasara anoshandisa nzira nhatu huru dzekuongorora muVietnam, imwe neimwe yakakodzera nharaunda dzakasiyana uye mashandisirwo adzo.
Masensa ePolarographic, anoratidzwa neERUN-SZ1S-A-K6, anonyanya kushandiswa mumakanzuru nemaindasitiri. Aya anoyera musiyano uripo pakati pemaelectrode anoshanda uye anoreva (kazhinji masisitimu egold electrode), achipa kunyatsojeka (±1%FS) uye mhinduro nekukurumidza (<30s). PaHo Chi Minh City's Water Plant Nhamba 3, mhedzisiro yepolarographic yakaratidza 98% kuenderana nemazinga eDPD emurabhoritari. Michina yekuchenesa otomatiki yakabatanidzwa (masisitimu emabhurashi) inowedzera nguva yekuchengetedza kusvika kumwedzi miviri kusvika mitatu - zvakakosha kumvura yeVietnam ine algae yakawanda.
Ma sensor emagetsi anoramba achishandiswa (semuenzaniso, masisitimu eLAR) anoshanda zvakanaka mukushandiswa kwakaoma kwemvura yakasviba. Nekushandisa simba rakagadzika uye kuyera simba rinobuda, zvinoratidza kudzivirira kwakanyanya kukanganiswa kwesulfides nemanganese - kunyanya kukosha mumvura dzinopisa dzekuchamhembe kweVietnam. Chivako chemvura yakasviba cheCan Tho AKIZ chinoshandisa tekinoroji iyi pamwe chete nemasisitimu eNitriTox kuchengetedza chlorine inobuda pa0.5-1.0mg/L.
Masensa eOptical colorimetric seBlueview's ZS4 anoshanda zvinoenderana nezvinodiwa zvema "multi-parameter" zvinotarisirwa nebhajeti. Kunyangwe zvichinonoka (maminitsi 2-5), kugona kwavo kweDPD-based multi-parameter (pH/turbidity panguva imwe chete) kunoderedza mari yemagetsi emudunhu. Kuvandudzwa kwe "microfluidic" kwakaderedza kushandiswa kwe "reagent" ne90%, zvichirerutsa mutoro wekugadzirisa.
Tinogonawo kupa mhinduro dzakasiyana-siyana dze
1. Mita inobatwa nemaoko yemhando yemvura ine maparameter akawanda
2. Sisitimu yeFloating Buoy yemhando yemvura ine maparameter akawanda
3. Bhurashi rekuchenesa otomatiki re sensor yemvura ine ma parameter akawanda
