Microbial optimum PH

Kev ua haujlwm ntawm microbial thiab cov metabolism hauv kev sib raug zoo nrog tus nqi pH. Qhov pH ntau ntawm cov kab mob feem ntau yog 4.5-9, thaum lub pH zoo tshaj plaws yog 6.5-7.5. Thaum pH qis dua 6.5, cov kab mob pib sib tw nrog cov kab mob, thiab thaum pH yog 4.5, cov kab mob yuav siv tag nrho cov txiaj ntsig hauv lub tank biochemical, uas yuav cuam tshuam rau kev daws teeb meem ntawm sludge. Thaum pH siab tshaj 9, tus nqi metabolic ntawm cov kab mob yuav raug cuam tshuam.

Qhov ntau ntawm pH qhov xav tau rau cov kab mob sib txawv yog txawv. Hauv kev kho mob aerobic, pH tuaj yeem sib txawv ntawm 6.5 thiab 8.5; Hauv kev kho kab mob anaerobic, pH ntawm cov kab mob yuav tsum nruj, thiab pH yuav tsum nyob nruab nrab ntawm 6.7 thiab 7.4.

Feem ntau PH yuav raug hloov kho hauv lub tank txias, tab sis kuj tseem yuav siv cov khoom siv Submersible kom cov PH muaj zog zoo ib yam thiab ruaj khov.
