城市污泥是城市污水处理厂经各级处理净化污水而产生的沉积物，主要来自初沉池和剩余污泥的排放。
The higher the sludge concentration and the flux were, the easier it was for the sludge particles to deposit on the membrane surface.
污泥浓度愈高，膜通量愈大时，活性污泥颗粒愈易在膜面沉积。
The test shows the flow in the modified forebay is remarkably improved, the efficiency of the pump raised and the sludge deposit reduced.
试验研究表明，改进后的前池水流流态明显改善，水泵运行效率得到提高，并有效减少了前池的泥沙淤积。
