絮凝剂在河湖污泥脱水中的应用研究

The Application and Research of Flocculants in Dehydration of Lake Sludge

河湖水质在一定程度上受河湖底泥的影响,要彻底改善水质就要对沉积的污泥进行处理。研究发现,有机高分子絮凝剂的种类及投加比例对河湖污泥脱水效果有着很大的影响。通过对特定湖泊污泥中投加不同型号、不同比例、不同用量的絮凝剂,比较其脱水效果,可以筛选出针对该种污泥的最佳絮凝剂投加使用方式,从而为污泥的大规模脱水减量化、资源化处置工程提供依据,并可大幅提高河湖污泥处置的经济效益,最终为河湖水质的改善提供了基础条件。

The water quality of the lake is influenced by the sludge.To decontaminate the sludge is the precondition of the water quality.The kinds and concentration of Polymeric Flocculants have great influence on the dehydration of lake sludge.The experiment results show the best method in efficiency of dehydration.The method offers advantages of deduction and resource of the lake sludge.
