依据低温外热重铬酸钾氧化一比色法原理，测定城市污水处理厂脱水污泥有机碳（OC）含量。实验结果显示：泥样取样量在0．005～0．04g之间，测定吸光度在标准曲线上；对12个平行泥样进行0c测定，相对标准偏差0．66％，精密度较好；泥样OC含量总体均值斗置信区间范围（0．3914，0．3947）较小，准确度较好。

According to the principle of low-temperature external-heat potassium dichromate oxida- tion-photo-colorimetric method, organic carbon （ OC ） of sludge was determined in the municipal sewage plant. The results showed that absorbance of 0.005 ~ 0.04 g dry sludge was in the standard curve; relative standard deviation of the twelve parallel sludges OC results was 0.66% -the precision was well, and fiducially interval range of their population mean was smaller-the accuracy was also well.
