中山市印染废水 CODcr与 BOD5相关性研究

摘要

通过对中山市印染废水中的CODcr和BOD5的平行测试和分析，通过考察印染污水的特点，得出印染污水中CODcr和BOD5相关性的研究和方法。根据相关性建立CODcr和BOD5相关方程，由该方程预测出的BOD5值进行验证，只需估算出一个稀释比就可以满足BOD5的测定要求，从而简化BOD5测定步骤，指导印染废水处理设施的日常运行。%The linear equations between COD cr and BOD5 values of the dyeing effluent in Zhongshan City were gained by processing a great deal of water quality data .BOD5 values could be predicted by the equation .It is concluded that only one dilution ratio can meet the demand of the measurement of BOD 5 to guide the facilities of dyeing effluent .
