Keeb kwm ntawm Kev Saib Xyuas Dej Zoo thiab Kev Tswj Xyuas Cov Tshuaj chlorine hauv Nyab Laj
Raws li kev lag luam sai sai thiab kev loj hlob hauv nroog Esxias yav Qab Teb lub teb chaws, Nyab Laj tau ntsib ob qhov kev nyuaj siab ntawm kev tswj hwm dej. Cov ntaub ntawv pov thawj qhia tias kwv yees li 60% ntawm cov dej hauv av thiab 40% ntawm cov dej saum npoo av hauv Nyab Laj tau kis mus rau qhov sib txawv, nrog rau cov kab mob microbial thiab tshuaj lom neeg ua rau muaj kev txhawj xeeb tseem ceeb. Hauv cov khoom siv dej, cov tshuaj chlorine residual - raws li cov tshuaj chlorine uas tseem tshuav los ntawm kev tua kab mob - ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm dej. Tsis txaus cov tshuaj chlorine tsis tu ncua tsis tu ncua tshem tawm cov kab mob hauv cov kav dej, thaum ntau theem tuaj yeem tsim cov tshuaj tua kab mob carcinogenic byproducts. Lub koom haum WHO pom zoo kom tswj cov tshuaj chlorine seem ntawm 0.2-0.5mg / L hauv cov dej haus, thaum Nyab Laj QCVN 01: 2009 / BYT tus qauv xav kom tsawg kawg yog 0.3mg / L ntawm cov kav xa dej.
Nyab Laj cov dej hauv vaj tse ua rau pom kev tsis sib xws hauv nroog thiab nyob deb nroog. Cov cheeb tsam hauv nroog xws li Hanoi thiab Ho Chi Minh City muaj cov khoom siv ua tiav tab sis ntsib cov teeb meem los ntawm cov kav dej laus thiab kev kis kab mob thib ob. Kwv yees li ntawm 25% ntawm cov neeg nyob deb nroog tseem tsis muaj kev nkag tau rau cov dej haus uas muaj kev nyab xeeb, vam khom feem ntau ntawm cov dej tsis zoo lossis cov dej saum npoo av. Txoj kev loj hlob tsis sib xws no tsim kom muaj ntau yam kev xav tau rau kev tshuaj xyuas cov tshuaj chlorine - cov cheeb tsam hauv nroog xav tau kev ua haujlwm siab, lub sijhawm online hauv lub sijhawm tiag tiag thaum cov cheeb tsam nyob deb nroog saib xyuas qhov tseem ceeb ntawm kev siv nyiaj thiab kev ua haujlwm yooj yim.
Txoj kev saib xyuas ib txwm muaj ntsib ntau yam teeb meem kev coj ua hauv Nyab Laj:
- Kev soj ntsuam hauv chav kuaj xav tau 4-6 teev los ntawm cov neeg ua haujlwm cob qhia
- Phau ntawv sampling yog txwv los ntawm Nyab Laj lub elongated geography thiab complex dej systems
- Cov ntaub ntawv tsis sib txuas tsis muab kev nkag siab txuas ntxiv rau cov txheej txheem hloov kho
Cov kev txwv no tau tshwm sim tshwj xeeb thaum muaj xwm txheej ceev xws li 2023 chlorine leak tshwm sim ntawm ib qho chaw ua lag luam hauv xeev Dong Nai.
Residual chlorine sensor technology muab cov kev daws teeb meem tshiab rau Nyab Laj kev saib xyuas dej. Niaj hnub nimno sensors feem ntau siv electrochemical cov hauv paus ntsiab lus (polarography, qhov voltage tsis tu ncua) los yog kho qhov muag lub hauv paus ntsiab lus (DPD colorimetry) ncaj qha ntsuas dawb thiab tag nrho cov tshuaj chlorine, xa cov ntaub ntawv real-time ntawm wired los yog wireless kev twb kev txuas. Piv nrog rau cov txheej txheem ib txwm muaj, cov thev naus laus zis no muab cov lus teb sai dua (<30 vib nas this), qhov raug siab dua (± 0.02mg / L), thiab kev saib xyuas qis dua - tshwj xeeb tshaj yog haum rau Nyab Laj cov huab cua sov thiab kev saib xyuas kev xav tau.
Nyab Laj txoj kev pib "Smart City" thiab "Ntawm Dej" hauv lub tebchaws muaj kev txhawb nqa txoj cai rau kev siv tshuaj chlorine sensor. Xyoo 2024Vietnam Residual Chlorine Analyzer Kev Lag Luam Kev Txhim Kho thiab Kev Tshawb Fawb Txog Kev Lag Luamqhia tias tsoomfwv npaj yuav txhim kho kev saib xyuas hauv nroog loj, ua ntej hauv online chlorine cov cuab yeej saib xyuas. Ib yam li ntawd, Ministry of Health tau nce qhov yuav tsum tau saib xyuas ntau zaus los ntawm ib hlis mus rau txhua hnub ntawm cov ntsiab lus tseem ceeb, ntxiv kev xav tau rau cov thev naus laus zis hauv lub sijhawm.
Cov lus: Cov tshuaj chlorine residual txwv hauv Nyab Laj Cov Qauv Dej Zoo
| Hom dej | Txuj | chlorine txwv (mg / L) | Kev soj ntsuam zaus |
|---|---|---|---|
| Municipal Haus Dej | QCVN 01:2009/BYT | ≥0.3 (qhov kawg) | Txhua hnub (cov ntsiab lus tseem ceeb) |
| Lub raj mis dej | QCVN 6-1: 2010/BYT | ≤0.3 | Rau batch |
| Pas Dej | QCVN 02:2009/BYT | 1.0-3.0 Nws | Txhua 2 teev |
| Tsev kho mob pov tseg | QCVN 28:2010/BTNMT | ≤1.0 | Tsis tu ncua |
| Muaj Cua Txias | Kev lag luam Standards | 0.5-2.0 | Txheej txheem-nyob |
Lub khw muag khoom Nyab Laj tau qhia txog kev sib koom ua ke thoob ntiaj teb hauv zos, nrog cov khoom lag luam hwm zoo li lub teb chaws Yelemees LAR thiab Amelikas HACH ua tus thawj tswj hwm qib siab thaum Suav cov tuam txhab xws li Xi'an Yinrun (ERUN) thiab Shenzhen AMT nce kev lag luam los ntawm kev sib tw nqi. Qhov tshwj xeeb, cov tuam txhab Nyab Laj tau nkag mus rau kev tsim khoom siv hluav taws xob los ntawm kev sib koom tes thev naus laus zis, xws li Hanoi-raws li lub tuam txhab cov nqi qis tau ua tiav hauv cov dej num hauv tsev kawm ntawv nyob deb nroog.
Kev saws me nyuam hauv zos ntsib ntau yam teeb meem kev hloov pauv:
- Tropical humidity cuam tshuam rau electronics
- High turbidity cuam tshuam qhov tseeb ntawm optical
- Kev siv hluav taws xob tsis sib xws hauv thaj chaw nyob deb nroog
Cov neeg tsim khoom tau teb nrog kev tiv thaiv IP68, kev tu tsis siv neeg, thiab kev xaiv lub hnub ci zog los txhim kho kev ntseeg siab hauv Nyab Laj cov kev xav tau.
Cov Ntsiab Cai Txuj Ci thiab Nyab Laj-Tshwj Xeeb Hloov Kho
Cov tshuaj chlorine residual siv peb txoj kev tshawb nrhiav thawj zaug hauv Nyab Laj, txhua qhov tsim nyog rau ntau qhov chaw thiab kev siv.
Polarographic sensors, ua piv txwv los ntawm ERUN-SZ1S-A-K6, ua tus thawj coj hauv nroog thiab kev lag luam. Cov kev ntsuas tam sim no sib txawv ntawm kev ua hauj lwm thiab siv electrodes (feem ntau kub electrode systems), muab siab precision (± 1% FS) thiab ceev teb (<30s). Ntawm Ho Chi Minh City Water Plant No.3, cov txiaj ntsig polarographic pom tau tias 98% kev sib raug zoo nrog cov qauv kuaj DPD. Kev sib xyaw ua haujlwm tsis siv neeg tu tshuab (txhuam tshuab) txuas sijhawm txij nkawm mus rau 2-3 lub hlis - qhov tseem ceeb rau Nyab Laj cov dej algae nplua nuj.
Cov ntsuas hluav taws xob tas li (xws li LAR lub tshuab) ua tau zoo hauv cov ntawv siv dej khib nyiab. Los ntawm kev siv lub peev xwm ruaj khov thiab ntsuas qhov tshwm sim tam sim no, lawv ua kom pom kev cuam tshuam zoo tshaj plaws tiv thaiv sulfides thiab manganese - tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau yav qab teb Nyab Laj cov organic-hnyav dej. Lub tuam txhab Can Tho AKIZ muaj cov dej khib nyiab siv cov cuab yeej no nrog rau cov tshuab NitriTox kom tswj cov tshuaj chlorine tawm ntawm 0.5-1.0mg / L.
Optical colorimetric sensors zoo li Blueview's ZS4 pab nyiaj txiag-conscious multi-parameter xav tau. Txawm hais tias qeeb qeeb (2-5 feeb), lawv DPD-raws li ntau qhov ntsuas muaj peev xwm (ib txhij pH / turbidity) txo cov nqi rau cov nqi hluav taws xob hauv xeev. Microfluidic kev nce qib tau txiav cov reagent noj los ntawm 90%, txo cov nra hnyav.
Peb kuj tuaj yeem muab ntau yam kev daws teeb meem rau
1. Handheld meter rau ntau qhov ntsuas dej zoo
2. Floating Buoy system rau ntau qhov ntsuas dej zoo
3. Tsis siv neeg tu txhuam rau ntau qhov ntsuas dej ntsuas
4. Ua tiav cov servers thiab software wireless module, txhawb RS485 GPRS / 4g / WIFI / LORA / LORAWAN
