冷轧浓碱废水系统设计及运行优化

摘要

The design and operation optimization process of cold rolling concentrated al-kaline wastewater system of a steel enterprise are introduced in detail, including process se-lection, calculation of process parameters and selection of the main equipment. The system uses the air floatation device as the core equipment in the pretreatment part and adopts the bio-contact oxidation method as the core treatment process in the bio-chemical part. The system has high automation level and is easy to operate and maintain.%详细介绍了某钢铁企业冷轧浓碱废水系统的设计和运行优化过程。包括工艺流程的选择、工艺参数的计算、主要设备的选型等。系统以气浮设备作为预处理部分核心设备，以生物接触氧化法作为生化部分核心处理工艺。系统自动化水平高，运行维护方便。
