M'makampani owunikira madzi, ndikukhulupirira kuti aliyense ayenera kuchita chidwi ndiBOD analyzer.Malinga ndi muyezo wadziko lonse, BOD ndiye kufunikira kwa okosijeni wachilengedwe.Mpweya wa okosijeni wosungunuka umagwiritsidwa ntchito.Njira zodziwika bwino za BOD zimaphatikizira njira ya sludge, njira ya coulometer, njira ya dilution inoculation, njira ya microbial electrode, njira ya mercury differential pressure ndi njira ya mercury-free differential pressure njira, ndi zina zotero. kuwunika, njira yopondereza yopanda mercury yopanda mercury yowunikira BOD yakhala yotchuka kwambiri pakati pa makasitomala.Mfundo ya mercury-free differential pressure sensor ndiyo kugwiritsa ntchito njira yopuma kuti muyese BOD.Kuchepa kwa okosijeni mu malo otsekeka kumabweretsa kusiyana kwina kwa kuthamanga, ndipo kusiyana kwa kuthamanga kumeneku kumatha kuzindikirika ndi kafukufuku wozindikira kuthamanga.Mu dongosolo lotsekedwa, tizilombo tating'onoting'ono timene timatulutsa carbon dioxide pamene tikudya mpweya, ndipo mpweya woipa umatengedwa ndi sodium hydroxide, zomwe zimapangitsa kusintha kwa mpweya.Kusintha kwamphamvu kumayesedwa ndi sensor sensor ndikusinthidwa kukhala mtengo wa BOD.Ubwino wake ndi: zolondola, zachangu, zopanda mercury, sizingayambitse kuipitsidwa kwachiwiri kwa chilengedwe, ndipo zimatha kukwaniritsa zofunikira pakuyesa ndi kuyang'anira chilengedwe.
Mitundu yodziwika bwino ya oyesa ma BOD opanda mercury pamsika ndi awa:Lianhua, HACH, Hanna, MettlerToledo, ThermoScientific, OAKTON, YSI,etc. Nthawi zambiri, mercury differential pressure BOD analyzer imasankhidwa kuti ikhale yowunikira mpweya chifukwa imatha kuyeza kukula kwa mphamvu ya mercury ndipo imatha kupanga ndondomeko yofananira malinga ndi zotsatira za kuyeza.Chida cha Lianhua chopanda mercury-free differential pressure BOD chimawonjezera chitetezo, chimachepetsa kugwiritsa ntchito masitepe oyesera ndi zinthu zomwe zimagwiritsidwa ntchito, ndipo ndichopulumutsa mphamvu komanso choteteza chilengedwe.
Njira yogwiritsira ntchito:
1. Ikani chitsanzo mu chidebe cha chitsanzo cha analyzer ndikugwira ntchito molingana ndi malangizo;
2. Ikani chidebe chachitsanzo mu analyzer, yatsani analyzer, ndipo ikani magawo oyezera;
3. Ikani kafukufuku wa analyzer mu chidebe cha chitsanzo ndikuyamba kuyeza;
4. Malingana ndi zotsatira zomwe zikuwonetsedwa ndi analyzer, lembani mtengo wa BOD;
5. Yeretsani chida choyezera, yeretsani chidebe choyezera, ndipo malizitsani kuyeza.
