Kupu Whakataki
Ko te tātaritanga o te Tono Hāora Matū (COD) tuku iho e hiahia ana ki ngā taputapu taiwhanga, ngā matū kino (dichromate), me ngā tukanga nakunaku roa. Engari, me pēhea mēnā ka taea e koe te aroturuki i te COD, te Tono Hāora Matū (BOD), te Waro Waro Katoa (TOC), me te paru i te wā kotahi, i te wā tūturu, me te kore he matū?
Mā te Pūoko COD Putanga RS485 Mamati (Tauira CS6603CD) ka taea tēnei mā te whakamahi i te hangarau Ngongo Ultraviolet (UV254). He maha ngā matū waro e mimiti ana i te mārama UV i te 254 nm. Mā te ine i te mimiti i tēnei roangaru motuhake, ka tatau tonu te pūoko i ngā uara COD, BOD, me te TOC ōrite – kāore he matū, kāore he whakaritenga tauira, ā, kāore he parahanga.
Ka whakauruhia hoki e tēnei pūoko te utu mō te paru, mā te whakamahi i tētahi ine motuhake hei whakatika i te pokanoa mai i ngā totoka whakatārewatia, me tētahi paraihe horoi-ake hei ārai i te poke koiora, kia mau ai te mahi pono mō te wā roa.
He māmā noa te whakamahi i tēnei pūoko. Anei te tukanga mahi noa:
Tāutanga
- Whakamaua te pūoko poutū, whakapae rānei ki roto i tētahi pūtau rere, i tētahi awa tuwhera, i tētahi atu rānei, tōia tika atu ki roto i te tāke mā te whakamahi i tētahi pupuri e tika ana.
- Honoa te atanga RS‑485 (Modbus) ki tō pūnaha pupuri raraunga, PLC, SCADA rānei. Ko te roa o te taura taunoa he 10 mita.
Whakakahangia
- Putanga DC 12V (±5%, iahiko <50 mA kāore he muru). He IP68 te whakatauranga o te pūoko, he pai mō te mahi i raro i te wai tae atu ki te 1 pae te pēhanga.
Whakarerekētanga
- Mō te whakatūnga tuatahi, whakahaerehia he whakatikatika kaiwhakamahi kotahi, e rua rānei ngā tohu mā te whakamahi i tētahi otinga paerewa (hei tauira, KHP mō te COD/BOD/TOC). E taunakihia ana hoki kia kaua e whakatikatikahia ki te wai whakakore iona.
- Kua rongoa kētia te whakatikatika wheketere; ka whakatikatikahia e te kaiwhakamahi te whakatikatika mō ngā matihiko wai motuhake.
Tīmata te Ine
- Ka whakaputa te pūoko i ngā uara wā-tūturu mō te COD, te BOD, te TOC, me te pōuriuri mā te Modbus RTU.
- Ka taea te whakahohe ā-ringa, aunoa rānei i te paraihe horoi-ake (paraihe horoi) hei horoi i ngā matapihi whatu, kia roa ake ai ngā wā tiaki.
Te Takitaki me te Whakahaere Raraunga
- Whakauruhia ngā raraunga matihiko ki roto i tō pūnaha aunoa hei whakaoho i ngā whakaoho, hei whakarerekē i ngā tere whakapūngao, hei arotau rānei i te horopeta matū i roto i ngā tukanga maimoatanga wai para.
Ngā Whakatakotoranga Matua i te Tirohanga Poto
| Tawhā | Awhe | Te tika | Whakataunga |
|---|---|---|---|
| COD | 0.1 – 1500 mg/L (KHP) | <5% | 0.01 mg/rita |
| BOD | 0.1 – 900 mg/L (KHP) | <5% | 0.01 mg/rita |
| Ngā tuhinga o te kaupapa | 0.1 – 750 mg/L (KHP) | <5% | 0.1 mg/rita |
| Te pōuriuri | 0.1 – 4000 NTU | <3%, 0.2 NTU rānei | 0.1 NTU |
| Te pāmahana | +5 – 45°C | — | — |
He aha i whiriwhiri ai i tēnei pūoko?
- ✅Kāore he matū, kāore he para, kāore he parahanga
- ✅ Putanga COD, BOD, TOC, me te paru i te wā kotahi
- ✅ Te utunga o te paru mō te tino tika i roto i ngā tauira tūturu
- ✅ Paraihe horoi-ā-koe mō te iti o te tiaki
- ✅ Modbus RS‑485 mamati mō te whakaurunga ngāwari
- ✅IP68, e tika ana mō ngā āhuatanga parae kino
Whakamutunga
Ahakoa kei te aroturuki koe i te wai e rere ana, te wai para, te wai tukatuka rānei i roto i tētahi whare tāone, i tētahi whare ahumahi rānei, ka tukuna e te pūoko COD Putanga RS485 Digital he huarahi tere, ma, me te whai hua ki te whakakapi i ngā tātaritanga COD tuku iho. Ka whakaratohia he raraunga tonu, wā-tūturu e āwhina ana i a koe ki te kite wawe i ngā kaupapa poke, te arotau i ngā tukanga maimoatanga, me te whakaiti i ngā utu whakahaere - me te whakakore i ngā matū kino.
