Umgangatho waManzi we-BOD kwi-Intanethi Ukujongisisa okuzenzekelayo koMfanekiso oboniswayo

I-BOD Umgangatho waManzi kwi-Intanethi iMonitor ezenzekelayo

Inkcazelo emfutshane:

Isampulu yamanzi, isisombululo se-potassium dichromate digestion, isisombululo se-sulfate yesilivere (i-sulfate yesilivere njenge-catalyst yokudibanisa inokuthi isebenze ngokuthe tye ngokuthe tye i-fatty compound oxide echanekileyo) kunye nomxube we-sulfuric acid ukufudumala ukuya kwi-175 ℃, isisombululo se-ion oxide ye-dichromate ye-organic matter emva kokutshintsha kombala, uhlalutyi ukufumana utshintsho lwe-BOD ye-conroversion yokutshintsha kunye nokutshintsha kombala we-conroversion. isiqulatho se-ion sobungakanani bemiba ephilayo ene-oxidizable.

Umgaqo weMveliso:

Amanziisampuli, isisombululo se-potassium dichromate digestion, isisombululo sesilivere yesulfate (isilivere yesulfate njenge-catalyst yokudibanisa inokuthi isebenze ngokuthe tye ngokuthe ngqo kwikhonkco elinamafutha e-oxide edibeneyo) kunye nomxube we-sulfuric acid ufudunyezwe ukuya kwi-175 ℃, isisombululo se-ion oxide ye-dichromate ye-organic matter emva kokutshintsha kombala, uhlalutyi lokubona utshintsho kwi-conversion yombala, kunyeBODimveliso yexabiso kunye nokusetyenziswa komxholo we-ion ye-dichromate yobuninzi bezinto eziphilayo eziphilayo.

3.Iiparamitha zoBugcisa:

Hayi.	Igama	Iiparamitha zobuGcisa
1	Uluhlu lweSicelo	Le mveliso ifanelekile kumanzi amdaka anemfuno ye-oksijini yeekhemikhali kuluhlu lwe-10 ~2I-000mg / L kunye ne-chloride yoxinaniso engaphantsi kwe-2.5g / L Cl-. Inokwandiswa kumanzi amdaka ngoxinaniso lwekloridi ngaphantsi kwe20g/L Cl- ngokwemfuno yokwenene yabathengi..
2	Iindlela zoVavanyo	I-Potassium dichromate yotyiswa kwiqondo lokushisa eliphezulu kunye nokuzimisela kwe-colorimetric.
3	Uluhlu lokulinganisa	10~2000mg/L
4	Umda osezantsi wokuFumana	3
5	Isigqibo	0.1
