Isingeniso
Ukuhlaziywa kwe-Traditional Chemical Oxygen Demand (COD) kudinga imishini yelabhorethri, ama-reagent ayingozi (i-dichromate), kanye nezinqubo zokugaya ezinde. Kodwa kuthiwani uma ungaqapha i-COD, i-Biochemical Oxygen Demand (BOD), i-Total Organic Carbon (TOC), kanye ne-turbidity ngasikhathi sinye, ngesikhathi sangempela, ngaphandle kwama-reagent?
I-Digital RS485 Output COD Sensor (Model CS6603CD) yenza lokhu kwenzeke ngokusebenzisa ubuchwepheshe be-Ultraviolet Absorption (UV254). Amakhemikhali amaningi e-organic amunca ukukhanya kwe-UV ku-254 nm. Ngokulinganisa ukumunca kulo mkhawulo we-wavelength othize, i-sensor ibala njalo amanani alinganayo e-COD, BOD, kanye ne-TOC - konke ngaphandle kwamakhemikhali, akukho ukulungiselela isampula, futhi akukho ukungcola.
Le sensor iphinde ihlanganise isinxephezelo sokungcoliswa kwamanzi, isebenzisa isilinganiso esihlukile sokulungisa ukuphazamiseka okuvela ezintweni eziqinile ezilengisiwe, kanye nebhulashi elizihlanzayo ukuze kuvinjelwe ukungcoliswa kwezinto eziphilayo, okuqinisekisa ukusebenza okuthembekile kwesikhathi eside.
Izinyathelo Ezilula Zokusebenza
Ukusebenzisa le sensor kulula. Nansi indlela ejwayelekile yokusebenza:
Ukufakwa
- Faka inzwa ngokuqondile noma ngokuvundlile kuseli lokugeleza, vula isiteshi, noma uyicwilise ngqo ethangini usebenzisa isibambi esifanele.
- Xhuma isikhombimsebenzisi se-RS‑485 (Modbus) ohlelweni lwakho lokufaka idatha, i-PLC, noma i-SCADA. Ubude bekhebula elizenzakalelayo buyimitha eyi-10.
Iba namandla
- Ihlinzeka nge-DC 12V (±5%, amandla kagesi <50 mA ngaphandle kwe-wiper). Inzwa inesilinganiso se-IP68, ifanele ukusebenza ngaphansi kwamanzi kuze kufike ku-1 bar pressure.
Ukulinganisa
- Ukuze usethe okokuqala, yenza ukulinganisa komsebenzisi kwephuzu elilodwa noma amabili usebenzisa isisombululo esijwayelekile (isb., i-KHP ye-COD/BOD/TOC). Ukulinganisa okungaphelele ngamanzi angenawo i-ion nakho kuyanconywa.
- Ukulinganiswa kwefekthri sekuvele kugciniwe; ukulungiswa okuhle kokulinganiswa komsebenzisi kwe-matrices yamanzi athile.
Qala Ukulinganisa
- Inzwa ikhipha amanani esikhathi sangempela e-COD, BOD, TOC, kanye ne-turbidity nge-Modbus RTU.
- Ibhulashi elizihlanzayo (i-wiper) lingaqaliswa ngesandla noma ngokuzenzakalelayo ukuze kuhlanzwe amafasitela abonakalayo, kwandiswe izikhawu zokulungisa.
Ukugcina Nokulawula Idatha
- Hlanganisa idatha yedijithali ohlelweni lwakho lokuzenzakalela ukuze uqalise ama-alamu, ulungise amazinga omoya, noma uthuthukise umthamo wamakhemikhali ezinqubweni zokwelashwa kwamanzi amdaka.
Imininingwane Eyinhloko Ngokushesha
| Ipharamitha | Ibanga | Ukunemba | Isixazululo |
|---|---|---|---|
| I-COD | 0.1 – 1500 mg/L (KHP) | <5% | 0.01 mg/L |
| I-BOD | 0.1 – 900 mg/L (KHP) | <5% | 0.01 mg/L |
| I-TOC | 0.1 – 750 mg/L (KHP) | <5% | 0.1 mg/L |
| Ukuvuvukala | 0.1 – 4000 NTU | <3% noma 0.2 NTU | 0.1 NTU |
| Izinga lokushisa | +5 – 45 °C | — | — |
Kungani Ukhetha Le Sensor?
- ✅Azikho izinto ezivuselelayo, akukho mfucuza, akukho ukungcola
- ✅ Ukukhishwa kwe-COD, BOD, TOC kanye ne-turbidity ngasikhathi sinye
- ✅ Isinxephezelo se-Turbidity ngokunemba okuphezulu kumasampula angempela
- ✅ Ibhulashi lokuzihlanza ukuze lingabi nomonakalo omkhulu
- ✅ I-Digital RS‑485 Modbus ukuze kube lula ukuhlanganisa
- ✅I-IP68, ifanele izimo zasensimini ezinzima
Isiphetho
Kungakhathaliseki ukuthi uqapha amanzi anamandla, angcolile, noma acutshungulwa esitshalweni sikamasipala noma sezimboni, inzwa ye-Digital RS485 Output COD inikeza enye indlela esheshayo, ehlanzekile, futhi engabizi kakhulu kunezihlaziyi ze-COD zendabuko. Inikeza idatha eqhubekayo, yesikhathi sangempela ekusiza ukuthi uthole izehlakalo zokungcola kusenesikhathi, uthuthukise izinqubo zokwelapha, futhi unciphise izindleko zokusebenza - konke lokhu ngenkathi ususa ama-reagent ayingozi.
