用HYDRONET高效气浮技术替代市政污水厂二沉池的试验研究

The Study Using High-efficient Air-floating Technica HYDRONET Replacing the Secondary Sedimentation Tanks in Municipal Wastewater Treatment Plant

在活性污泥法中,二沉池占地面积可观。利用悬浮—附着型纤毛填料技术加瑞士高效气浮技术HYDRONET和某市政污水处理厂卡鲁赛尔氧化沟后的辐流式二沉池的沉淀效果的对比试验,可知出水SS小于2 mg/L,优于同期该污水处理厂二沉池出水,得出该高效工艺组合可以替代市政污水处理厂二沉池的结论,并可节省土地。

In the activated sludge process, the secondary sedimentation tanks＇ footprints are vast. Comparing the tests results of effluent in suspension-adhering style cilium filler add the efficient air-floating technique with that of the spoke-fluent style secondary sedimentation tank of a municipal wastewater plant with Carrousel Oxidation ditch. So we have a conclusion that this combined technique can replace the secondary sedimentation tanks in municipal wastewater treatment plant and can save space at the same time.
