摘　　要：生化需氧量是反映水中有机化合物等需氧物质含量的一个综合指标,稀释接种法可以用于测定大浓度水样的五日生化需氧量,其间稀释方法的选择会对结果产生一定影响。因此,本文研究了直接稀释与间接稀释两种方法,以期为大浓度水样测定时的稀释方法选择提供参考。Biochemical oxygen demand is a comprehensive index reflecting the content of aerobic substances such as organic compounds in water,the dilution inoculation method can be used to determine the five-day biochemical oxygen demand of large-concentration water samples,during which the choice of the dilution method will have a certain impact on the results.Therefore,this paper studies two methods,direct dilution and indirect dilution,in order to provide a reference for the selection of dilution methods when measuring large concentration water samples.
