| 摘 要： | 介绍了图解法的原理，实验条件，实验方法，并采用图解法和标准法，通过对国家标准样品和有代表性的实际水样进行ＢＯＤ５测定和比较，所有试验样品的测定值均在标准样品的已知值范围内。图解法与标准法相比，两者误差不超过±５％，证明了图解法的准确性，合理性和实用性。图解法是标准法的改进，它简化了实验操作，减少了误差，使测定计算更准确。 |

| Abstract: | This paper deals with the principle, process, experimental conditions and instruments of Graphical Method (GM) for determining BOD5. The BOD5 tests of some State Ceritified Reference Samples (SCRS) and representative wastewater samples were run with Standard Method (SM) and Graphical Method respectively. The BOD values of SCRS obtained by GM are in the range of known BOD values. The results from GM are compared with the results obtained by SM,the errors are within 5% or less. Experimental results show that Graphical Method simplifies the operation of BOD5 determination, reduces the error and makes the determination more precise. |
