Ihe nyocha BOD nke na-enweghị Mercury (Manometry)

N'ime ụlọ ọrụ nlekota oru mmiri, ekwenyere m na onye ọ bụla kwesịrị ịmasị yaIhe nyocha BOD. Dabere na ọkọlọtọ mba, BOD bụ ihe achọrọ oxygen biochemical. Oxygen agbazere ewerie n'ime usoro ahụ. Usoro nchọpụta BOD nkịtị na-agụnye usoro sludge arụ ọrụ, usoro coulometer, usoro inoculation dilution, usoro microbial electrode, usoro nrụgide mercury dị iche iche na usoro nrụgide dị iche iche na-enweghị mercury, wdg. nlekota oru, usoro nrụgide dị iche iche na-enweghị mercury maka nchọpụta BOD aghọwo ihe na-ewu ewu n'etiti ndị ahịa. Ụkpụrụ nke ihe mmetụta nrụgide dị iche iche na-enweghị mercury bụ iji usoro iku ume tụọ BOD. Mbelata ikuku oxygen n'ime oghere a kpachiri anya ga-emepụta ihe dị iche iche nrụgide, enwere ike ịhụ ọdịiche nrụgide a site na nyocha nhụta nrụgide. N'ime usoro mechiri emechi, microorganisms dị na nlele ahụ na-emepụta carbon dioxide ka ha na-eri oxygen, na carbon dioxide nke a na-emepụta na-etinye ya na sodium hydroxide, na-ebute mgbanwe n'ikuku. A na-atụle mgbanwe nrụgide site na ihe mmetụta nrụgide ma gbanwee n'ime uru BOD. Uru ya bụ: ezi, ngwa ngwa, enweghị mercury, agaghị ebute mmetọ nke abụọ na gburugburu ebe obibi, ma nwee ike izute ihe achọrọ nke nyocha na nlekota gburugburu ebe obibi.

Ụdị ụdị nrụgide BOD dị iche iche na-enweghị mercury n'ahịa gụnyere:Lianhua, HACH, Hanna, MettlerToledo, ThermoScientific, OAKTON, YSI,wdg. N'ikwu okwu n'ozuzu, a na-ahọrọ mercury differensial pressure BOD analyzer ka ọ bụrụ onye nyocha ikuku n'ihi na ọ nwere ike ịlele nha nke nrụgide dị iche iche nke mercury ma nwee ike ịrụ nhazi kwekọrọ na nsonaazụ nha. Ngwa BOD dị iche iche nke na-enweghị mercury nke Lianhua na-abawanye nchekwa, na-ebelata ojiji nke usoro nnwale na ihe oriri, ma na-echekwa ike yana enyi na gburugburu ebe obibi.

Jiri usoro:
1. Tinye ihe nlele n'ime ihe nlele nke onye nyocha ma rụọ ọrụ dịka ntuziaka ahụ si dị;
2. Tinye ihe nlele ahụ n'ime onye nyocha, gbanye onye nyocha, ma tọọ nha nha;
3. Tinye nyocha nke onye nyocha n'ime ihe nlele wee malite nha;
4. Dị ka nsonaazụ gosipụtara site na nyocha, dekọọ uru BOD;
5. Hichaa ngwa ihe, hichaa ihe nlele, ma mechaa nha.
