Wastewater Treatment







بخشی از مقاله

Energy Measurement (5)

Biochemical (Biological) Oxygen Demand (BOD)

Carbonaceous BOD: aerobic heterotrophs

Decompose organic molecules to minerals (CO2) and residues

Obtain their cell carbon from the organic material

Nitrogenous BOD: obligate aerobic chemoautotrophs

Characteristics of nitrifiers (chemoautotrophs)

DO < 2 mg/L action slow

DO < 0.5 mg/L action ceases

Optimum pH: 8.0;  pH < 7.2: slows down

More sensitive than heterotrophs to toxins

Slow growers (longer sludge age required)
