摘要
采用加压和减小排水路径的方法对污泥进行了浓缩试验研究，得到了沙网柱直径及所加压力对污泥浓缩效果影响的关系。试验结果对未来污水厂的设计和现有污水厂的改进有一定的指导作用。
The experimental study was conducted on the sludge thickening properties by adding up pressure and shortening water flowing path, by which the relations between the diameters of sand columns and adding up pressures and the effects on sludge water thickening were obtained. The research results will be the guidance to the design of future Sewage Treatment Plants and to the improvement of the constructed Sewage Treatment Plants.
