分别采用差温加热法和脂磷法测定活性污泥和粉末活性炭（PAC）混合样品、实际生物粉末活性炭（BPAC）样品的生物质量浓度，比较两种方法的准确度和精度，建立生物粉末活性炭生物质量浓度的有效检测方法。结果表明，差温加热法的测定结果较脂磷法具有更高的准确度和精度，其平均相对误差（绝对值）约为10%，标准差约为2.5%，均优于脂磷法［测定高生物量样品时平均相对误差（绝对值）约为26%，标准差约为9%；测定低生物量样品时平均相对误差（绝对值）约为15%，标准差约为4%］。测定实际BPAC样品的生物质量浓度时，差温加热法的相对标准差为7.60%，而脂磷法为8.88%，进一步验证了差温加热法测定准确度和精度更高的优势。

Differential heating method and lipid- phosphorus method were used to determine the biomass concentrations of activated sludge-powdered activated carbon (PAC) mixed sample and actual biological powdered activated carbon (BPAC) sample, and the accuracies of the two methods were compared to find a more efficient method for measuring the biomass concentration of BPAC.The biomass concentration measured by differential heating method had higher accuracy and precision than that of lipid-phosphorus method. The average relative error (absolute value) and standard deviation of the differential heating method were about 10% and 2.5%, while those of the lipid-phosphorus method for the high biomass samples were about 26% and 9%, and for the low biomass samples were about 15% and 4%. When the biomass concentration of the actual BPAC sample was determined, the relative standard deviation of the differential heating method was 7.60%, while that of the lipid-phosphorus method was 8.88%, which further verified the advantages of higher accuracy and precision of the differential heating method.
