Inject the water sample or pretreated water sample into the culture bottle, put the carbon dioxide absorbent (NaOH) into the absorption cup at the mouth of the bottle, seal the culture bottle, and put it into the biochemical culture box. When the sample to be tested is cultured at a constant temperature of 20 ± 1 ℃ for five days, the water sample in the bottle will undergo the biological oxidation reaction at a certain stirring speed. The organic matter is transformed into oxides of nitrogen, carbon and sulfur, and the carbon dioxide gas is absorbed by sodium hydroxide. The oxygen in the upper space of the culture bottle continuously supplies the oxygen demand of the microorganism in the water sample, and the pressure difference is generated in the culture bottle. By detecting the height of mercury in the glass tube, the BOD value of the water sample in the specified measurement period can be calculated.
