| 摘 要： | 根据水质COD重铬酸钾法，实测了市场上5种常见品牌洗衣粉的COD负荷值，得到其平均值为0．328（w／w）（绝干洗衣粉）。由我国使用量计算得到2005年洗衣粉形成的COD总量为88．87×10^4t，这相当于当年全国工业和生活COD排放总量的6．3％，全国生活COD排放总量的10．3％，2005年我国洗衣粉消费过程COD产污系数为1．86g／（d·人），需要对洗衣粉消费形成的COD总量水平予以必要的关注。

| Abstract: | Based on the standard method of COD determination with acidic potassium dichromate for wastewater,the experimental results showed that the average COD load of five powder detergent samples was 0.328 kg/kg(oven dry detergent).Total COD amount from domestic consumption of powder detergents was 0.8887 million tons in 2005,which accounted for 6.3% of total COD amount discharged from all industries and urban population and 10.3% of total COD amount discharged from urban population in 2005,China.The COD formation... |
