Ikhwalithi Yamanzi Ye-CODcr Ku-inthanethi Yokuqapha Okuzenzakalelayo Isithombe Esifakiwe

I-CODcr Water Quality On-line Automatic Monitor

Incazelo emfushane:

I-Chemical oxygen demand (COD) ibhekisela ekuhlanganiseni kwenqwaba komoyampilo osetshenziswa ama-oxidants lapho i-oxidizing izinto eziphilayo nezincishiswayo ezingaphili kumasampula amanzi anama-oxidants aqinile ngaphansi kwezimo ezithile. I-COD iphinde ibe yinkomba ebalulekile ekhombisa izinga lokungcoliswa kwamanzi ngezinto ezinciphisa imvelo nezingaphili.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

1.Ukubuka konke komkhiqizo:

I-analyzer ingasebenza ngokuzenzakalelayo nangokuqhubekayo isikhathi eside ngaphandle kokuya ngokuya ngezilungiselelo zesayithi. Asetshenziswa kakhulu emanzini angcolile aphuma ezimbonini zokungcoliswa kwendle, amanzi angcolile enqubo yezimboni, amanzi angcolile embonini yokukhuculula indle, amanzi angcolile esikhungo sikamasipala sokuhlanza indle nezinye izikhathi. Ngokuya ngobunkimbinkimbi bezimo zokuhlolwa kwesayithi, isistimu yokwelashwa kwangaphambili ehambisanayo ingakhethwa ukuze kuqinisekiswe ukuthi inqubo yokuhlola ithembekile, imiphumela yokuhlola inembile, futhi ihlangabezana ngokugcwele nezidingo zezikhathi ezihlukene.

2.Isimiso somkhiqizo:

Amasampula amanzi, isixazululo se-potassium dichromate digestion, isixazululo sesiliva sulfate (isiliva sulfate njenge-catalyst singangezwa ku-oxidize linear aliphatic compounds ngempumelelo) kanye nengxube ye-sulfuric acid egxilile eshiselwe ku-175℃. Umbala wezinhlanganisela eziphilayo kusixazululo se-dichromate ion oxidation uzoshintsha. I-analyzer ithola ukushintsha kombala bese iguqulela uguquko lube ivelu ye-COD bese ikhipha inani.Inani le-ion ye-dichromate esetshenzisiwe lilingana nenani lezinto eziphilayo ezi-oxidizable, okuyi-COD.

3.Amapharamitha wobuchwepheshe:

Cha.	Igama	Imininingwane Yezobuchwepheshe
1	Ibanga Lohlelo	Ifanele amanzi angcolile ane-COD ebangeni elingu-10~5,000mg/L kanye nokuhlushwa kwe-chloride ngaphansi kuka-2.5g/L Cl-. Ngokwesidingo sangempela samakhasimende, inganwetshwa emanzini angcolile ane-chloride engaphansi kuka-20g/L Cl-.
2	Izindlela Zokuhlola	I-Potassium dichromate digestion ekushiseni okuphezulu, ukuzimisela kwe-colorimetric
3	Ibanga lokulinganisa	10 ~5,000mg/L
4	Umkhawulo ophansi Wokuthola	3
5	Isixazululo	0.1
6	Ukunemba	±10% noma ±8mg/L(Thatha inani elikhulu)
7	Ukuphindaphinda	10% noma 6mg/L(Thatha inani elikhulu)
8	I-Zero Drift	±5mg/L
9	I-Span Drift	±10%
10	Umjikelezo wokulinganisa	Ubuncane bemizuzu engama-20. Ngokwesampula sangempela samanzi, isikhathi sokugaya singasethwa kusuka kumaminithi angu-5 kuya kwangu-120.
11	Isikhathi samasampula	Isikhawu sesikhathi (esilungisekayo), ihora elibalulekile noma imodi yokulinganisa yokucupha ingasethwa.
12	Ukulinganisa umjikelezo	Ukulinganisa okuzenzakalelayo (izinsuku ezingu-1-99 ezilungisekayo), ngokuya ngamasampula wangempela wamanzi, ukulinganisa okwenziwa ngesandla kungasethwa.
13	Umjikelezo wesondlo	Isikhathi sokunakekela singaphezu kwenyanga eyodwa, cishe imizuzu engama-30 isikhathi ngasinye.
14	Ukusebenza komshini womuntu	Isibonisi sesikrini esithintwayo nokokufaka kweziyalezo.
15	Ukuzivikela kokuzihlola	Isimo sokusebenza siwukuzihlolela, okungavamile noma ukwehluleka kwamandla ngeke kulahlekelwe idatha. Iqeda ngokuzenzakalelayo ama-reactants ayinsalela futhi iqalisa kabusha umsebenzi ngemva kokusetha kabusha okungavamile noma ukuhluleka kwamandla.
16	Ukugcinwa kwedatha	Isitoreji sedatha esingekho ngaphansi kwesigamu sonyaka
17	Okokufaka kubonwa	Shintsha ubuningi
18	Isixhumi esibonakalayo sokukhiphayo	Ama-RS amabili485okukhiphayo kwedijithali, Okukodwa kwe-analog ye-4-20mA
19	Izimo zokusebenza	Ukusebenza endlini; izinga lokushisa 5-28 ℃; umswakama ohlobene≤90% (akukho ukujiya, awekho amazolo)
20	Ukusetshenziswa Kwempahla Yamandla
