综合测定活性污泥参数的研究及应用

Research on the comprehensive determination of activated sludge parameters and their application

给出了活性污泥处理废水工艺中,曝气池污泥沉降比、污泥浓度、污泥指数、污泥灰分和挥发分、污泥负荷、泥龄、排泥量等参数的综合测定方法、试验结果、计算及论证。通过综合方法测定污泥的多项参数,最大相对误差为4.1%,最小相对误差为0.2%,平均误差为2.0%,均在允许的相对误差5%范围之内。

Regarding the treatment technology of activated sludge comprehensive determination, such as mari and volatilization, sludge load, sludge sedimentation ratio, sludge sludge age, sludge discharging wastewater, some parameters of the concentration, sludge indexes, sludge quantity of aeration pond, etc., the experimental results, calculation and demonstration are given. The maximum relative error of the parameters is 4.1%, the minimum relative error is 0.2%, and the average error is 2.0%. All of them are in the range of 5% of the allowable relative error.
