摘　　要：介绍了HCM-100 BOD5测定仪压差法测量原理及测定方法,利用压差法对标准样品、石油化工污水样品进行分析,并与稀释接种法进行对比,从分析结果看,HCM-100 BOD5测定仪压差法与稀释接种法测量BOD5的准确度和精密度无显著差异,符合国家标准质控允许的范围内。HCM-100 BOD5测定仪克服了稀释接种法工作量大操作繁琐、所需试剂多、稀释倍数难确定等缺点,具有操作简便、快速,节省人力、物力等优点,可用于对石油化工污水的分析。The pressure-difference method measuring principle and determination method of HCM- 100 BOD5 instrument were introduced. Using the pressure- difference method of standard samples, petroleum chemical sewage samples were analyzed. Compared with dilute inoculation method, the analysis results showed that accuracy and precision of BOD5 measuring by HCM-100 BOD5 instrument pressure difference method and dilution inoculation method had no significant differences conformed to the overcame the weakness, such as trival difficult to determine diluted times, the and can be used for petroleum chemical state standards quality-control allowed range. The pressure-difference method dilution inoculation method operation, big workload, too much reagents using, operation is fast and simple, saves manpower and material resources advantages, wastewater analysis.
