离心脱水干化处理渗滤液剩余污泥研究

Study on the Application of Centrifugal Dewatering and Drying Treatment of Residual Sludge from Leachate

介绍了采用离心脱水和投加石灰固化剂的组合方式处理渗滤液剩余污泥,达到污泥含水率60%的处理效果。研究了污泥浓度、絮凝剂投加浓度和脱水污泥含水率的关系,处理后的干污泥能够达到GB16889-2008中填埋场填埋处置的要求。

The combination of centrifugal dewatering and adding lime curing agent was introduced to treat residual sludge in leachate treatment, which can reduce sludge moisture content to 60%. To study the relationship between sludge concentration, flocculants concentration and moisture content of dehydrated sludge, the treated dry sludge can meet requirements of the landfill treatment of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste(GB16889-2008).
