| 摘 要： | 以模拟污染物为测量体系,分析测量模拟污水的BOD5、CODCr、ORP,讨论BOD5/CODCr与ORP的相关性。研究结果表明：对于单独含葡萄糖、可溶性淀粉、尿素、牛肉膏的模拟系统,两者的相关系数分别达0.992 7,0.992 1,0.991 9,0.996 5;对于含有葡萄糖等的人工废水,两者的相关系数达到0.982 1;在可生化处理体系中,BOD5/CODCr与ORP相关性良好。实际应用中,可尝试以ORP指标代替BOD5/CODCr作为水体可生化性判定的标准。

| Abstract: | The BOD5,CODCr and oxidation/reduction potential（ORP） of simulated wastewater were measured and analyzed and the correlation between the BOD5/CODCr and ORP was studied using the simulated pollutants as the measurement system.The research result shows that： the correlation coefficients for simulation systems containing only glucose,dissolvable starch,carbamide or beef extract are 0.9927,0.9921,0.9919 and 0.9965 respectively;the correlation coefficient for artificial wastewater containing glucose and other substances reaches 0.9821;the correlation between them is good in biodegradable systems.For real-world applications,the ORP indicator can be used as the measure for the biodegradability of water body in stead of BOD5/CODCr. |
