膜生物反应器出水COD与UV254之间的线性关系

摘要

利用实验室内搭建的膜生物反应器对餐饮废水进行处理。分别测得多组出水的CODCr和UV254值，并用Origin软件分析处理数据后得到COD与UV254之间的线性关系。通过此关系式，由UV254值可直接得到COD，既缩短了试验时间，又提高了试验效率。%In this paper restaurant wastewater was treated by membrane bioreactor in the laboratory. The values of CODCr and UV254 of effluent were analyzed by Origin software and a linear relationship between COD and UV254 was found. With the relationship,COD value can be obtained directly from UV254 value,which can reduce the experimental time and improve experiment efficiency.
