| 摘 要： | 絮凝沉降法一般用于城市污水污泥和工业废水的处理，在城市河、湖底泥的处理方面还未有大规模使用的报道，为了研究絮凝沉降法在河、湖底泥处理的作用，无锡市河海、湖泊生态修复与资源化工程技术研究中心与江苏江达生态科技有限公司联合开展了2个示范工程．利用絮凝沉降法对河、湖底泥进行处理，分析了絮凝剂对水质常规指标的影响．分析结果为：①絮凝沉降法可以有效降低水中SS，COD，BOD和TP的浓度，特别是对TP和磷酸盐的去除效果显著．最大可达80％以上；②絮凝剂可以有效降低泥浆水中氨氮（NH3-N）和总氮（TN）的浓度，但是余水中的NH3-N和TN的浓度比河水中的高．

| Abstract: | Flocculation sedimentation is used to sewage treatment plant and industrial wastewater. But large -scale application of flocculation for the sediment treatment of urban river and lake is few reported. River, Lake and Sea Ecological Restoration and Resources Engineering and Technology Research Institution of Wuxi and Jiangsu Jiangda Ecological Science and Technology Corporation established two demonstration projects to study the sediment treatment by flocculation sedimentation and the impacts of the floccula... |
