蒙维科技PVA废水处理与回用工程设计

内蒙古蒙维科技有限公司废水处理工程设计规模为200 m3/h,采用带选择器的活性污泥法作为废水处理的核心工艺。介绍了废水的水质水量、处理工艺流程和各处理单元设计参数,并对设计和运行中的经验进行了总结。运行实践表明,该废水处理工程运行良好,处理效果稳定,处理出水达到《污水再生利用工程设计规范》(GB50335—2002)中"再生水用作冷却用水的水质控制指标",全部回用作循环冷却水。

Design of the project on PVA wastewater treatment and reuse in Inner Mongolia Mengwei Technology Co.,Ltd.

The design capacity of Inner Mongolia Mengwei Technology Co.,Ltd. for wastewater treatment project is 200 m3/h. Activated sludge treatment process with a biological selector has been chosen as the core treatment process. The quality and quantity of the influent water ,the layout of the treatment processes ,and the design parameters of every treatment unit are introduced in detail ,and the experiences in the design and operation are summarized. The operation practice shows that the wastewater treatment project runs well ,treatment effects are stable ,and the treated effluent reaches the“controlled targets of water quality for the reclaimed water used as cooling water”,specified in the Design Specification of Wastewater Recycling Project (GB 50335—2002). The effluent can all be reused as cir-culating cooling water successfully.
