【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88.87×104t,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1.86 g/(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。更多还原

【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 coefficient from powder detergent consumption was 1.86 g/(day·person)-1 in 2005.People should care the COD from the domestic consumption of powder detergents.更多还原
