Abstract Based on the previous research results, a flow chart for BOD rapid analysis was determined. The effects of temperature on the stability of measurement result and the initial BOD concentration on measurement time were investigated. The reproducibility of the results and the linear range were also studied. The experimental results indicated that constant temperature could keep the initial DO and the microbial activity relatively stable and guarantee the stability of measurement. The maximal relative error was less than 7.7%, which meet the needs of BOD rapid analysis. It took different time for determining samples containing different BOD values, however, it took less than 15 min at the initial BOD value below 200 mg/l. The linear range for BOD rapid measurement using this system was between 5-200 mg/l.
