摘　　要：为倡导低碳生活方式,减少污染物的排放,本文进行了生活污水低碳减排的研究。测试了日常生活中经常废弃的液体食品、调味品、洗涤用品和淘米水的COD数值,结果表明:测试的生活中废弃液体的COD值非常高,食用油最高为2 282 210 mg/L,淘米水最低为13 595 mg/L,远高于一般生活污水的COD数值。通过理论分析,对上述物质的COD植进行了计算,发现测试值和计算值大体相近,相对偏差小于8%,说明测试结果是可信的。分析COD数值较高的原因,是这些物质中含有较多的含碳有机物。通过减排数据说明,低碳生活应该从每个人做起,要做好日常生活中的COD减排工作。In order to advocate the low-carbon living style and reduce the emission of pollutants, low carbon and emission reduction of municipal wastewater were investigated. The chemical oxygen demand （COD） of several kinds of substance was measured, including liquid food, liquid condiment, liquid detergent and washing water office. The results show that the values of COD in these substances are rather high with the maximum of 2.28×106 mg/L of cooking oil and the minimum of 1.36×104 mg/L of washing water office, which is largely higher than the value of COD in municipal wastewater. The COD of these kindsof substance was also calculated through theoretical analysis, and the results show that the amount of COD through calculation is almost equal to that through measuring and the absolute relative deviation is less than 8%, which indicates that the measuring value is credible. The reason for the high COD is that there are large amount of organic compounds in these substance, and the suggestion is proposed through emission reduction calculation that every member in our society Should lead a low-carbon life and reduce the emission of COD in daily life.
