Kwishishini lokuhlola umgangatho wamanzi, ndikholelwa ukuba wonke umntu kufuneka athabathekeBOD analyzer. Ngokomgangatho wesizwe, i-BOD yimfuno ye-oksijini ye-biochemical. Ioksijini enyibilikileyo esetyenzisiweyo kwinkqubo. Iindlela eziqhelekileyo zokubona i-BOD ziquka indlela ye-sludge esebenzayo, indlela ye-coulometer, indlela ye-dilution inoculation, indlela ye-microbial electrode, indlela yoxinzelelo lwe-mercury eyahlukileyo kunye ne-mercury-free-different pressure method, njl. Ngokunyuka kongcoliseko lwamanzi asekhaya kwiminyaka yakutshanje kunye nokomelezwa kokusingqongileyo. ukubeka iliso, indlela yoxinzelelo lwe-mercury-free-free differential yokufumanisa i-BOD iye yathandwa kakhulu phakathi kwabathengi. Umgaqo-siseko we-mercury-free differential sensor sensor kukusebenzisa indlela yokuphefumula ukulinganisa i-BOD. Ukuncitshiswa kweoksijini kwindawo evaliweyo kuya kuvelisa umahluko othile woxinzelelo, kwaye lo mahluko woxinzelelo unokubonwa ngeprobe yokuva uxinzelelo. Kwinkqubo evaliweyo, i-microorganisms kwisampulu ivelisa i-carbon dioxide ngelixa idla i-oksijini, kwaye i-carbon dioxide eyenziwayo ifakwe yi-sodium hydroxide, okubangelwa utshintsho kuxinzelelo lomoya. Utshintsho loxinzelelo lulinganiswa yinzwa yoxinzelelo kwaye luguqulelwe kwixabiso le-BOD. Iinzuzo zayo zezi: ngokuchanekileyo, ngokukhawuleza, i-mercury-free, ayiyi kubangela ungcoliseko lwesibini kwindalo, kwaye inokuhlangabezana neemfuno zokuvavanya nokubeka iliso.
Iibrendi eziqhelekileyo zoxinzelelo lwasimahla lwemekyuri abavavanyi beBOD kwimarike ziquka:Lianhua, HACH, Hanna, MettlerToledo, ThermoScientific, OAKTON, YSI,njl. Ngokuqhelekileyo, i-mercury differential pressure ye-BOD analyzer ikhethwa njenge-analyzer yomgangatho womoya kuba inokulinganisa ubungakanani be-mercury differential pressure kwaye ingenza inkqubo ehambelanayo ngokweziphumo zokulinganisa. Isixhobo se-BOD esingafaniyo se-mercury-free se-mercury se-Lianhua sonyusa ukhuseleko, sinciphisa ukusetyenziswa kwamanyathelo okulinga kunye nezinto ezisetyenziswayo, kwaye sigcina amandla ngakumbi kwaye sinobuhlobo nokusingqongileyo.
Sebenzisa inkqubo:
1. Beka isampuli kwisitya sesampuli ye-analyzer kwaye usebenze ngokwemiyalelo;
2. Beka isitya sesampuli kwi-analyzer, vula i-analyzer, kwaye usethe imilinganiselo yokulinganisa;
3. Beka i-probe ye-analyzer kwisitya sesampuli kwaye uqale umlinganiselo;
4. Ngokweziphumo eziboniswe ngumhlalutyi, bhala ixabiso le-BOD;
5. Coca isixhobo sokulinganisa, coca isikhongozeli sesampulu, kwaye ugqibezele umlinganiselo.
