青岛市麦岛污水处理厂扩建工程设计

Process design in extension and upgrading project of Maidao Wastewater Treatment Plant in Qingdao City

以青岛市麦岛污水处理厂扩建工程为例,介绍了在城市中心区域采用强化预处理扩建污水处理厂的MULTIFLO沉淀池+BIOSTYR曝气生物滤池处理工艺的设计。该工艺具有处理效率高、占地面积小、全面除臭、噪声低、利用沼气发电节能、对周围环境影响小等特点。较好地解决了在城市中心区域建设污水处理厂对周围环境影响的问题。

The extension and upgrading project of Maidao Wastewater Treatment Plant in Qingdao City is presented as a case study. High density primary lamellar settler MULTIFLO and BAF process BIOSTYR are introduced as an ideal application for this project situated in central ur- ban area. This process provides high treatment efficiency while occupying a small footprint. In addition, the plant includes facilities for odor treatment, noise reduction and energy recovery by bio- gas production and co-generation, and has little environmental impact. This case study demonstrates the successful handling of the environmental issues arising from the construction of wastewater treatment plant in highly urbanized area.
