| 中文摘要: |
| 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。 |
| 英文摘要: |
| Based on the standard method of COD determination with acidic potassium dichrom ate forwastewater, the experimentalresultsshowed thatthe average COD load offive powder detergentsamples was0.328 kg/kg(oven dry detergent). TotalCOD amountfrom domestic consumption ofpowder detergents was 0.8887 milliontonsin 2005, which accounted for6.3% oftotalCOD amountdischarged from allindustriesand urban population and 10.3% oftotalCOD amountdischarged from urban population in 2005, China. The COD formation coefficientfrom powderdetergentconsumption was1.86 g/(day· person) - 1 in 2005. Peopleshould caretheCOD from the domestic consumption ofpowderdetergents. |
