摘　　要：通过对市政污水中的BOD_5和COD_(Cr)的平行测试和分析,考察了市政污水的特点,得出市政污水中BOD_5和COD_(Cr)相关性的研究方法。根据相关性建立BOD_5和COD_(Cr)。相关方程,由该方程可利用COD_(Cr)的值推算BOD_5的值,快速测定BOD_5。由此可通过COD_(Cr)来指导污水设施的日常运行。Through the parallel measurement and analysis of BOD5 and CODCr of the municipal waste water of Lianyungang, this article studies the characteristics of the waste water of the city and gives out the way to study the relativity of the BOD5 and CODCr of the municipal waste water . According to the relativity, the formula of BOD5 and CODCr can be established and using this formula, the value of BOD5 can be fast determined by the value of CODCr. Thus we can direct the daily work of the sewage treatment establishment by the value of CODCr.

关 键 词：BOD5 CODCR 相关性
