Embonini yokuqapha izinga lamanzi, ngikholelwa ukuthi wonke umuntu kufanele athathekeI-BOD analyzer. Ngokwendinganiso kazwelonke, i-BOD iyisidingo se-oxygen ye-biochemical. I-oxygen encibilikile idliwe kule nqubo. Izindlela ezivamile zokuthola i-BOD zihlanganisa indlela yodaka ecushiwe, indlela ye-coulometer, indlela yokufaka i-dilution, indlela ye-microbial electrode, indlela ye-mercury differential pressure kanye nendlela yokucindezela okuhlukile kwe-mercury-free, njll. Ngokungcoliswa kwamanzi asekhaya okwandayo okubucayi eminyakeni yamuva kanye nokuqiniswa kokuvikelwa kwemvelo. ukuqapha, indlela yokucindezela ehlukile ye-mercury-free yokutholwa kwe-BOD isithandwa kakhulu phakathi kwamakhasimende. Umgomo wenzwa yokucindezela okuhlukile kwe-mercury-free ukusebenzisa indlela yokuphefumula ukukala i-BOD. Ukwehliswa komoyampilo endaweni evalekile kuzoveza umehluko othile wengcindezi, futhi lo mehluko wengcindezi ungazwakala ngophenyo oluzwa ingcindezi. Kusistimu evaliwe, ama-microorganisms kusampula akhiqiza i-carbon dioxide ngenkathi edla umoya-mpilo, futhi i-carbon dioxide ekhiqizwayo imuncwa i-sodium hydroxide, okuholela ekushintsheni komfutho womoya. Ukushintsha kwengcindezi kukalwa ngenzwa yokucindezela futhi kuguqulelwe inani le-BOD. Izinzuzo zayo yilezi: okunembile, okusheshayo, okungenayo i-mercury, ngeke kubangele ukungcoliswa kwesibili kwemvelo, futhi kungahlangabezana nezidingo zokuhlolwa nokuqapha kwemvelo.
Izinhlobo ezijwayelekile zabahloli be-BOD abahlukile be-mercury emakethe bahlanganisa:Lianhua, HACH, Hanna, MettlerToledo, ThermoScientific, OAKTON, YSI,njll. Ngokuvamile, i-mercury differential pressure BOD analyzer ikhethwa njenge-analyzer yekhwalithi yomoya ngoba ingakwazi ukukala usayizi we-mercury differential pressure futhi ingenza ukucubungula okuhambisanayo ngokwemiphumela yokulinganisa. Ithuluzi le-BOD elihlukile le-mercury-free mercury-free lenyusa ukuphepha, linciphisa ukusetshenziswa kwezinyathelo zokuhlola nezinto ezisebenzisekayo, futhi longa amandla futhi livumelana nemvelo.
Sebenzisa inqubo:
1. Faka isampula esitsheni sesampula se-analyzer futhi usebenze ngokulandela imiyalelo;
2. Faka isitsha sesampula ku-analyzer, vula i-analyzer, bese usetha imingcele yokulinganisa;
3. Faka i-probe ye-analyzer esitsheni sesampula bese uqala ukulinganisa;
4. Ngokwemiphumela evezwe umhlaziyi, qopha inani le-BOD;
5. Hlanza ithuluzi lokulinganisa, hlanza isitsha sesampula, bese uqedela ukulinganisa.
