高密度沉淀池+V型滤池工艺的再生水厂设计

On Design of Renewable Water Plant with High- density Sedimentation Tank & V-filters Process

邯郸市第一座再生水厂是以东污水处理厂二级出水为原水,采用"高密度沉淀池+V型滤池"处理工艺,设计总处理规模为6万m3/d。出水主要回用于城市杂用水及景观环境用水,部分回用于工业用水。介绍了工程的设计与运行情况,着重介绍了高密度沉淀池的设计参数与构造。运行结果表明,工艺运行情况稳定,出水水质达到设计要求。

The first reclaimed water reuse project in Handan is adopting the process of high-density sedimentation tank V-filters with the total processing scale of 6 ×104 m3/d and the raw water from Handan East Wastewater Treatment Plant. Most of the treated water is used as urban miscellaneous water and scenic water, less of it is used as industrial water. The project design and operation are introduced in the paper, among which the design parameters and structure of high-density sedimentation tank are emphasized. The running results show that the quality of treated water can meet the design requirement and the condition of process operation can keep stable.
