I-CODcr Ikhwalithi Yamanzi Ezenzakalelayo Ekwi-inthanethi Isithombe Esifakiwe

I-CODcr Water Quality On-line Automatic Monitor

Incazelo emfushane:

Isidingo se-chemical oxygen (COD) sibhekisela ekuqongeleleni okukhulu kwe-oxygen edliwa ama-oxidants lapho kufakwa i-oxidizing organic kanye ne-inorganic reduction stuff kumasampula amanzi anama-oxidants aqinile ngaphansi kwezimo ezithile. I-COD futhi iyinkomba ebalulekile ekhombisa izinga lokungcoliswa kwamanzi yizinto ezincishisa izinto eziphilayo kanye ne-inorganic.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

I-analyzer ingasebenza ngokuzenzakalelayo nangokuqhubekayo isikhathi eside ngaphandle kokufika ngokwezilungiselelo zesayithi. Isetshenziswa kabanzi emanzini angcolile okukhishwa ngumthombo wokungcola kwezimboni, amanzi angcolile enqubo yezimboni, amanzi angcolile esitshalo sokwelapha indle sezimboni, amanzi angcolile esitshalo sokwelapha indle sikamasipala kanye nezinye izikhathi. Ngokuya ngobunzima bezimo zokuhlola indawo, uhlelo lokwelapha oluhambisanayo lungakhethwa ukuqinisekisa ukuthi inqubo yokuhlola ithembekile, imiphumela yokuhlolwa inembile, futhi ihlangabezana ngokugcwele nezidingo zezikhathi ezahlukene.

2. Isimiso Somkhiqizo:

Amasampula amanzi, isixazululo sokugaya i-potassium dichromate, isixazululo se-silver sulfate (i-silver sulfate njenge-catalyst ingangezwa ukuze i-oxidize ama-compounds e-aliphatic aqondile kahle kakhulu) kanye nengxube ye-sulfuric acid egxilile eshiswa ku-175℃. Umbala wama-compounds e-organic kusisombululo se-dichromate ion oxidation uzoshintsha. I-analyzer ithola ushintsho lombala bese iguqula ushintsho lube yinani le-COD bese ikhipha inani. Inani lama-ion e-dichromate asetshenziswayo lilingana nenani lezinto eziphilayo ezikwazi uku-oxida, okuyi-COD.

2. Amapharamitha Obuchwepheshe:

Cha.	Igama	Imininingwane Yobuchwepheshe
1	Ibanga Lohlelo Lokusebenza	Ifanelekela amanzi angcolile ane-COD ebangeni eliphakathi kuka-10 ~ 5,000mg/L kanye nokuhlushwa kwe-chloride okungaphansi kuka-2.5g/L Cl-. Ngokwesidingo sangempela samakhasimende, inganwetshwa emanzini angcolile ane-chloride engaphansi kuka-20g/L Cl-.
2	Izindlela Zokuhlola	Ukugaya kwe-potassium dichromate ekushiseni okuphezulu, ukunqunywa kwemibala
3	Ububanzi bokulinganisa	10~5,000mg/L
4	Umkhawulo ophansi wokutholwa	3
5	Isixazululo	0.1
6	Ukunemba	±10% noma ±8mg/L (Thatha inani elikhulu)
7	Ukuphindaphinda	10% noma 6mg/L (Thatha inani elikhulu)
8	Ukuzulazula Okungazelelwe	±5mg/L
9	Ukukhukhuleka Kwesikhala	±10%
10	Umjikelezo wokulinganisa	Okungenani imizuzu engama-20. Ngokwesampula yamanzi yangempela, isikhathi sokugaya singasethwa kusukela kumaminithi ama-5 kuya kwangu-120.
11	Isikhathi sokuthatha isampula	Isikhawu sesikhathi (esilungisekayo), ihora elihlanganisiwe noma imodi yokulinganisa i-trigger ingasethwa.
12	Ukulinganisa umjikelezo	Ukulinganisa okuzenzakalelayo (okulungisekayo kwezinsuku ezingu-1-99), ngokwezibonelo zamanzi zangempela, ukulinganisa ngesandla kungasethwa.
13	Umjikelezo wokulungisa	Isikhathi sokulungisa singaphezu kwenyanga eyodwa, cishe imizuzu engama-30 isikhathi ngasinye.
14	Ukusebenza komuntu nomshini	Isibonisi sesikrini sokuthinta kanye nokufakwa kwemiyalelo.
15	Ukuzivikela kokuzihlola	Isimo sokusebenza siyazihlola, akujwayelekile noma ukwehluleka kwamandla ngeke kulahlekelwe idatha. Kususa ngokuzenzakalelayo ama-reactant asele bese kuqhubeka nomsebenzi ngemuva kokusetha kabusha okungajwayelekile noma ukwehluleka kwamandla.
16	Isitoreji sedatha	Isitoreji sedatha esingaphansi kwesigamu sonyaka
17	Isixhumi esibonakalayo sokufaka	Ubuningi bokushintsha
18	Isixhumi esibonakalayo sokukhipha	Ukukhishwa kwedijithali okubili kwe-RS485, Ukukhishwa okukodwa kwe-analog okungu-4-20mA
19	Izimo Zokusebenza	Ukusebenza ngaphakathi endlini; izinga lokushisa 5-28℃; umswakama ohlobene ≤90% (akukho ukujiya, akukho mazolo)
20	Ukusetshenziswa Kokunikezwa Kwamandla	I-AC230±10%V, 50~60Hz, 5A
