白鹤嘴水厂污泥干化处理研究

白鹤嘴水厂污泥属于含无机物较多的河水污泥，沉降性能较好，且比阻小，较容易脱水，经试验发现干化床的渗滤液的SS很低，小于排放标准，在试验中未发现樗泥堵塞滤层或穿透滤层的现象：经过投加高分子絮凝剂PAM的污泥，脱水速度加快，干化周期缩短了10d左右，使干化床的负荷能力明显提高。

Research on Sludge Drying Process in Baihezui Waterworks

The sludge in Baihezui Waterworks belonged to river sludge containing much mineral, have good thickening properties and dewaterablity with less specific resistance, the suspended solid of leaching liquor through the drying sand bed is very low and is always less than criterion of drainage. The phenomena that sludge choke the filter bed or penetrate through the filter bed is never happens during the test. While sludge is treated by polyacrylamide, course of air dehydration is accelerated obviously and the cycle of air dehydration is curtailed about ten days, the burthen of the drying bed is aggrandized distinctly.
