煤矿排放废水的化学耗氧量(COD)的特性及其测定方法的分析

Characteristic of chemical oxygen demand(COD)of wastewater discharged from coal mines and analysis of its measuring method

化学耗氧量测定,是化工污水处理中主要分析条件之一,它与污水处理质量、净化方法的选择等方面均有联系。以煤矿排放废水为例,着重对化学耗氧量(COD)的特性及其测定方法进行分析,以达到把握污水处理要点,提升污水处理效率的目的。

Chemical oxygen consumption(COD)measurement is one of the main analytical conditions in chemical wastewater treatment,which is related to the quality of wastewater treatment and the selection of purification methods.Taking the waste water discharged from coal mine as an example,this paper focuses on the analysis of the characteristics of chemical oxygen demand(COD)and its determination method,in order to grasp the main points of wastewater treatment and improve the efficiency of wastewater treatment.
