Principle:

Put water sample or pretreatment water sample into a culture bottle with carbon dioxide absorbent (eg: sodium hydroxide) in the absorb cup on bottle mouth, then seal the bottle and put in the special biochemical incubator, keep the temperature at 20±1℃ and continuously incubated for 5 days, water sample will carry out bio-oxidation reactionat a certain stirring speed. Organic matter in the water sample will be converted to the oxides of Nitrogen, Carbon and Sulfur and generate carbon dioxide absorbed by sodium hydroxide. At the same time, oxygen gets the continual supply. Oxygen consumption of microorganism results in air pressure difference. The water sample BOD5 value within a specific period can be calculated through measuring the height of mercury in the glass tube.
