摘要
为了降低农村生活污水处理设施尾水的检测成本,选取了一批苏沪地区农村生活污水处理设施,分析了农村生活污水处理设施尾水的水质特征,并探究了农村生活污水处理设施尾水中TOC和COD的相关性,得出TOC与COD的一次线性关系方程为COD=2.8225TOC+4.542,决定系数R^2=0.91,误差率在20%以内的概率为87.80%。
In order to reduce the cost of testing in the effluent of domestic sewage treatment equipment,selected a batch of rural domestic sewage treatment equipment in rural areas of Jiangsu and Shanghai,then explored the correlation between TOC and COD in the effluent of the equipment.The linear equation of TOC and COD is obtained:COD=2.8225TOC+4.542,R^2=0.91,the relative error is within 20%with a probability of 87.80%.
