摘要
为了解决河湖淤泥两种常用清淤方式存在的瓶颈问题,整合的化学工艺涉及前置分拣设备、淤泥调理改性、絮凝浓缩和压滤脱水,获得较低的淤泥含水率,实现减量化和资源化利用的环保目标,同时减轻目前河湖淤泥清淤工程面对填埋场的负担。
In order to solve the bottleneck problems of two commonly used dredging methods to treat silt of rivers and lakes, theintegrated chemical process involves pre-sorting equipment, sludge conditioning modification, flocculation concentration and Pressure filtration dehydration. The lower water content of the sludge was obtained from the process. Environmental protection purpose for volume reduction and resource utilization was gained. Moreover, the burden on landfill from desilting rivers and lakes was largely reduced.
