| 摘 要： | 研究了磁场对污水处理厂高M LSS(>4.5gL/)污泥沉降性能的影响。通过设计7组不同条件的磁化实验,考察了不同磁场强度的磁场对污泥沉降性能的影响;并利用数理统计分析中的假设检验原理将所得试验数据进行了均值假设检验,结果表明:磁场的确对污泥沉降性能有影响,其影响效果为:平行磁化优于垂直磁化,平行磁化中磁场强度越大效果越好。

| Abstract: | The effect of magnetic treatment for municipal sludge of the big MLSS on sedimentation was researched.Based on planning the magnetic experiment of seven different experimental conditions,the effect of magnetic treatment with three different degrees of density was investigated by using hypothesis-test theory to check the data of Sedimentation in the magnetic field.According to the collected hypothesis-test data,it can be assured that the effect of sedimentation for municipal sludge can be improved and the result shows that the parallel magnetic is better than the vertical magnetic,in the parallel magnetic the density is bigger and the effect is better. |
