摘要：一种污泥可降解有机碳DOC指标测定方法，包括：步骤S1，将污泥泥样通过重铬酸钾法进行加热消煮，则污泥样品中的有机碳会被过量重铬酸钾硫酸溶液氧化，其中有机质的碳元素会被氧化成二氧化碳，六价铬被还原成三价铬，可以根据有机碳被氧化前后重铬酸离子量的变化计算出有机碳的含量；步骤S2，将实验过程中记录的数据代入到原本用于测定化学需氧量的计算公式中，并将公式中氧的毫摩尔质量参数替换成碳的毫摩尔质量。通过利用化学实验定量测定可降解有机碳的数值，对原有用于计算的经验值参数进行校正，可用于精确核算各污泥处理处置工艺和路线的碳排放量。

摘要： A bleaching apparatus comprises a measurement chamber has a first substance, the amount of the first substance in the measurement chamber being known. A dosing unit inputs a second substance to the measurement chamber for causing a chemical reaction between the first substance and the second substance, one of the first substance and the second substance being chlorine dioxide and another of the first substance and the second substance being filtered sample from pulp slurry of a pulp process. At least one sensor performs detection of a property known to depend on the chemical reaction between the first substance and the second substance as a function of time. A data processing unit determines chemical demand of chlorine dioxide for washing loss in a bleaching subprocess on the basis of at least one value in the detected property within a known period of time after the input of the second substance.
