活性污泥-生物膜一体化反应器处理生活污水性能研究

Study on Domestic Wastewater Treatment with Activated Sludge-biofilm Integrative Reactor

针对中小城镇污水处理的特点开发了活性污泥-生物膜复合一体化反应器,该反应器实现了反应区和沉淀区一体化,综合了活性污泥法和生物膜法的优点,具有运行稳定、占地面积少、基建投资低、管理方便的优点,并具有较好的去除有机物和脱氮除磷能力。

A novel activated sludge-biofilm integrative reactor （ASBIR） was developed to treat the wastewater from medium and small towns. The reactor integrates the reaction zone and the sedimentation zone together into one unit, and makess full use of the advantages of both activated sludge and biofilm process. The reactor was characterized by the stability in the treatment effect,less use of land, less investment for construction and simple operation requirement. The experimental results showed that the activated sludge-biofilm integrative reactor has high efficiencies of COD and TP removal and can remove aminonia-N and TN at the same time.
