摘要
对采用差压式直读测定装置测定生化需氧量(BOD)的方法进行了研究,该方法操作简单、直观性好,简化了大量烦琐操作并可连续测定BOD。通过测压法与稀释接种法(测定BOD的国家标准方法)的对比及差异性统计检验,表明这两种方法没有显著性差异。经对实际水样的分析并与标准稀释法的分析结果进行比较,该方法准确度较高。
The determination method of BOD using pressure distinction instrument was studied because it has the advantages of simple operation, simplifies a lot of operating processes and BOD can be monitored continuously with the method.It is concluded that there is no obvious difference between manometric method and standard dilution inoculation method by the contrast of these two methods and the statistical check of the difference of these two methods.This method has been found to be reliable through comparing the analytical results of the water samples using these two methods.
