Umgangatho waManzi we-CODcr kwi-Intanethi Ukubeka iliso ngokuzenzekelayo kuMfanekiso oboniswayo

I-CODcr yoMgangatho waManzi kwi-Intanethi yeMonitor ezenzekelayo

Inkcazelo emfutshane:

Imfuno yeoksijini yeMichiza (COD) ibhekisa kuxinzelelo olukhulu lweoksijini esetyenziswa zii-oxidants xa i-oxidizing eziphilayo kunye nezinto ezincitshiswayo ezingaphiliyo kwiisampuli zamanzi ezine-oxidants ezomeleleyo phantsi kweemeko ezithile. I-COD ikwasisalathiso esibalulekileyo esibonisa iqondo lokungcoliseka kwamanzi ngezinto eziphilayo nezinciphisayo ezingaphiliyo.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-analyzer inokusebenza ngokuzenzekelayo kwaye ngokuqhubekayo ixesha elide ngaphandle kokuya ngokwezicwangciso zesayithi. Isetyenziswa ngokubanzi kumthombo wongcoliseko lokukhupha amanzi amdaka, inkqubo yamanzi amdaka enkqubo yoshishino, amanzi amdaka eplanti yokucoca ugutyulo lwamanzi amdaka, kwindawo kamasipala yokucoca amanzi amdaka kunye nezinye izihlandlo. Ngokobunzima beemeko zovavanyo lwendawo, inkqubo yonyango lwangaphambili ehambelanayo inokukhethwa ukuqinisekisa ukuba inkqubo yovavanyo inokuthenjwa, iziphumo zovavanyo zichanekile, kwaye zihlangabezana ngokupheleleyo neemfuno zezihlandlo ezahlukeneyo.

2. Umgaqo weMveliso:

Iisampulu zamanzi, isisombululo se-potassium dichromate sokwetyisa, isisombululo sesulfate yesilivere (isilivere yesulfate njenge catalyst inokongezwa kwi-oxidize linear aliphatic compounds ngendlela esebenzayo) kunye nomxube ogxininisiweyo wesulfuric acid ufudunyezwe kwi-175℃. Umbala wezinto eziphilayo kwi-dichromate ion oxidation isisombululo uya kutshintsha. I-analyzer ibona utshintsho lombala kwaye iguqule utshintsho kwixabiso le-COD kwaye ikhuphe ixabiso.

2. Iiparamitha zobuGcisa:

Hayi.	Igama	IiNgcaciso zobuGcisa
1	Uluhlu lweSicelo	Ifanelekile kumanzi amdaka kunye ne-COD kuluhlu lwe-10 ~ 5,000mg / L kunye noxinzelelo lwe-chloride ngaphantsi kwe-2.5g / L Cl-. Ngokwemfuno yokwenyani yabathengi, inokwandiswa kumanzi amdaka ngoxinaniso lwekloridi engaphantsi kwe-20g/L Cl-.
2	Iindlela zoVavanyo	I-Potassium dichromate digestion kwiqondo lokushisa eliphezulu, ukuzimisela kwe-colorimetric
3	Uluhlu lokulinganisa	10~5,000mg/L
4	Umda osezantsi wokuFumana	3
5	Isigqibo	0.1
6	Ukuchaneka	± 10% okanye ± 8mg/L(Thatha ixabiso elikhulu)
7	Ukuphindaphinda	10% okanye 6mg/L(Thatha ixabiso elikhulu)

10	Umjikelo womlinganiselo	Ubuncinci bemizuzu engama-20. Ngokwesampulu yangempela yamanzi, ixesha lokugaya linokusekwa ukusuka kwi-5 ukuya kwi-120 imizuzu.
11	Ixesha lesampulu	Ixesha lexesha (elinokulungiswa), iyure edibeneyo okanye imowudi yokulinganisa i-trigger inokusetwa.
12	Ulungelelwaniso umjikelo	Ukulinganisa okuzenzekelayo (i-1-99 iintsuku ezilungelelaniswayo), ngokweesampuli zamanzi zangempela, ukulinganisa ngesandla kunokusetwa.
13	Umjikelo wesondlo	Ixesha lesondlo lingaphezulu kwenyanga enye, malunga nemizuzu engama-30 ngexesha ngalinye.
14	Ukusebenza koomatshini bomntu	Isibonisi sesikrini sokuchukumisa kunye nokufakwa komyalelo.
15	Ukhuseleko lokuzijonga	Ubume bokusebenza kukuzixilonga, ukungaqhelekanga okanye ukungaphumeleli kwamandla akuyi kulahlekelwa yidatha. Isusa ngokuzenzekelayo ii-reactants ezishiyekileyo kwaye iphinda iqalise umsebenzi emva kokusetha ngokutsha okungaqhelekanga okanye ukusilela kombane.
16	Ukugcinwa kwedatha	Akukho ngaphantsi kwesiqingatha sonyaka yokugcina idatha
17	Ujongano lwegalelo	Tshintsha ubungakanani
18	Ujongano lwemveliso	Imveliso yedijithali ye-RS485 emibini, imveliso enye ye-analog ye-4-20mA
19	Iimeko zokusebenza	Ukusebenza ngaphakathi; ubushushu 5-28℃; ukufuma okuhambelanayo≤90% (akukho ukujiya, akukho mbethe)
