Mhedzisiro yeMvura Kutariswa Kwemhando uye Chlorine Kudzora Inodiwa muVietnam
Senyika inokurumidza kuita maindasitiri uye kuita maguta ekuSoutheast Asia nyika, Vietnam inotarisana nedzvinyiriro mbiri pakutonga zviwanikwa zvemvura. Huwandu hunoratidza ingangoita 60% yemvura yepasi uye makumi mana muzana emvura yepasi muVietnam yakasvibiswa kune akasiyana madhigirii, nekusvibiswa kwehutachiona uye kemikemikari ndiyo inonyanya kunetseka. Mumagadzirirwo emvura, chlorine yakasara - sechikamu chakasara cheklorini chinoshanda kubva mukuuraya hutachiona - inoita basa rakakosha mukuona kuchengetedzwa kwemvura. Kusakwana kwasara chlorine inotadza kuramba ichibvisa utachiona mumapaipi, nepo mazinga akawandisa anogona kugadzira carcinogenic disinfection byproducts. WHO inokurudzira kuchengetedza zvakasara zve chlorine zviri pakati pe 0.2-0.5mg/L mumvura yekunwa, ukuwo QCVN yeVietnam 01:2009/BYT mwero inoda shoma 0.3mg/L pakunoperera pombi.
Zvivakwa zvemvura zveVietnam zvinoratidza kusaenzana kukuru kwemadhorobha-kumaruwa. Nzvimbo dzemumadhorobha dzakaita seHanoi neHo Chi Minh Guta dzine masisitimu ekupa asi anotarisana nematambudziko kubva kumapombi ekuchembera uye kusvibiswa kwechipiri. Inosvika chikamu che25% chevagari vekumaruwa vachiri kushaya mvura yekunwa yakachena, vachivimba zvikuru nemvura isina kucheneswa zvakanaka kana pamusoro pemvura. Uku kusimukira kusina kuenzana kunogadzira zvakasiyana zvinodiwa zvetekinoroji yekutarisisa chlorine - nzvimbo dzemumaguta dzinoda kurongeka kwepamusoro, chaiyo-nguva online masisitimu nepo matunhu ekumaruwa achiisa pamberi mutengo-kushanda uye nyore kushanda.
Nzira dzechinyakare dzekutarisa dzinosangana nezvipingamupinyi zvekushandisa zvakawanda muVietnam:
- Ongororo yerabhoritari inoda maawa 4-6 nevashandi vakadzidziswa
- Manual sampling inomanikidzwa neVietnam's elongated geography uye yakaoma nzizi masisitimu
- Data yakadimburwa inotadza kupa ruzivo rusingaperi rwekugadzirisa maitiro
Izvi zvipingamupinyi zvakava pachena zvakanyanya panguva dzekukurumidzira senge 2023 chlorine leak chiitiko paki yemaindasitiri mudunhu reDong Nai.
Residual chlorine sensor tekinoroji inopa mhinduro nyowani dzeVietnam yekutarisa mvura. Masensa emazuva ano anonyanya kushandisa misimboti ye electrochemical (polarography, inogara voltage) kana optical misimboti (DPD colorimetry) kuyera zvakananga mahara uye yakazara chlorine, kuendesa chaiyo-nguva data kuburikidza newaya kana isina waya. Zvichienzaniswa nemaitiro echinyakare, tekinoroji iyi inopa mhinduro nekukurumidza (<30 masekonzi), kurongeka kwepamusoro (± 0.02mg/L), uye kuderera kwekugadzirisa - kunyanya kunoenderana neVietnam yekupisa kwemamiriro ekunze uye nedecentralized monitoring zvinodiwa.
Zvirongwa zveVietnam "Smart City" uye "Mvura Yakachena" chirongwa chenyika chinopa tsigiro yegwaro rekugamuchira chlorine sensor. Iyo 2024Vietnam Residual Chlorine Analyzer Indasitiri Kuvandudza uye Investment Research Reportinoratidza hurongwa hwehurumende hwekusimudzira masisitimu ekutarisisa mumaguta makuru, ichitungamira online chlorine yekutarisa michina. Saizvozvo, Ministry of Health yakawedzera inodiwa yekutarisa frequency kubva pamwedzi kusvika zuva nezuva panzvimbo dzakaoma, ichiwedzera kutyaira kudiwa kweiyo chaiyo-nguva matekinoroji.
Tafura: Residual Chlorine Limits muVietnam's Water Quality Standards
| Rudzi rweMvura | Standard | Chlorine Limit(mg/L) | Monitoring Frequency |
|---|---|---|---|
| Municipal Drinking Water | QCVN 01:2009/BYT | ≥0.3 (yekupedzisira) | Zuva nezuva (mapoinzi akakosha) |
| Mvura Yemabhodhoro | QCVN 6-1:2010/BYT | ≤0.3 | Per batch |
| Duhwino | QCVN 02:2009/BYT | 1.0-3.0 | Ese maawa maviri |
| Hospital Wastewater | QCVN 28:2010/BTNMT | ≤1.0 | Continuous |
| Industrial Cooling | Industry Standards | 0.5-2.0 | Process-dependent |
Musika weVietnamese sensor unoratidza kugarisana kwepasirese, nemhando dzekutanga seLAR yekuGermany neAmerica HACH inotonga zvikamu zvepamusoro ukuwo vagadziri veChinese vakaita seXi'an Yinrun (ERUN) neShenzhen AMT vachiwana mugove wemusika kuburikidza nemitengo yemakwikwi. Zvikuru, makambani eVietnam ari kupinda mukugadzira ma sensor kuburikidza nekudyidzana tekinoroji, senge Hanoi-based firm's low-mutengo sensors yakabudirira kuyerwa mumapurojekiti emvura ekumaruwa.
Kugamuchirwa munharaunda kunotarisana nematambudziko akawanda ekugadziriswa:
- Tropical humidity inokanganisa magetsi
- High turbidity inokanganisa kuona kwechokwadi
- Kuwanikwa kwemagetsi nguva nenguva kumaruwa
Vagadziri vakapindura neIP68 dziviriro, kuchenesa otomatiki, uye sarudzo dzesimba rezuva kusimudzira kuvimbika mumamiriro ekuda eVietnam.
Technical Principles uye Vietnam-Yakananga Adaptation
Residual chlorine sensors anoshandisa nzira nhatu dzekutanga dzekuona muVietnam, imwe neimwe inokodzera nharaunda dzakasiyana uye mashandisirwo.
Polarographic sensors, yakaenzanisirwa neERUN-SZ1S-A-K6, inotonga kuisirwa kwemadhorobha uye maindasitiri. Aya anoyera mutsauko wazvino pakati pekushanda uye rengedzo maelectrode (kazhinji goridhe electrode masisitimu), achipa chaiyo chaiyo (± 1% FS) uye nekukurumidza kupindura (<30s). PaHo Chi Minh City's Water Plant No.3, mhinduro dzepolarographic dzakaratidza 98% kuenderana nerabhoritari DPD zviyero. Yakabatanidzwa otomatiki yekuchenesa masisitimu (mabhurashi masisitimu) anowedzera nguva dzekugadzirisa kusvika kumwedzi 2-3 - yakakosha kumvura yeVietnam ine algae yakawanda.
Constant voltage sensors (semuenzaniso, LAR's masisitimu) anokunda mukuoma kwemvura yetsvina yekushandisa. Nekushandisa zvakagadziriswa zvinogoneka uye kuyera mhedzisiro ikozvino, vanoratidza kwepamusoro kupindira kuramba kurwisa sulfides uye manganese - kunyanya yakakosha kumaodzanyemba kweVietnam kwemvura inorema-inorema. Iyo Can Tho AKIZ indasitiri yemvura yetsvina chirimwa inoshandisa tekinoroji iyi padivi peNitriTox masisitimu kuchengetedza effluent chlorine pa0.5-1.0mg/L.
Optical colorimetric sensors seBlueview's ZS4 inoshandisa bhajeti-inoziva akawanda-parameter zvinodiwa. Kunyangwe ichinonoka (2-5 maminetsi), yavo DPD-yakavakirwa akawanda-parameter kugona (panguva imwe chete pH/turbidity) inoderedza mutengo wezvishandiso zvepurovhinzi. Kufambira mberi kwe Microfluidic kwakacheka kushandiswa kwe reagent ne90%, kurerutsa mitoro yekugadzirisa.
Tinogonawo kupa zvakasiyana-siyana mhinduro dze
1. Handheld mita yemhando yemvura yakawanda-parameter
2. Inoyangarara Buoy system yemhando yemvura yakawanda-parameter
3. Otomatiki yekuchenesa brashi kune yakawanda-parameter mvura sensor
4. Yakazara seti yemaseva uye software isina waya module, inotsigira RS485 GPRS / 4g/WIFI/LORA/LORAWAN
