工程设计中红矾钠的废水治理方案

Disposal project of waste water from the production of sodium dichromate in engineering design

介绍红矾钠生产的工艺流程、废水污染情况。根据其工艺特点,分析废水的排放点和排放量,确定废水循环利用的理论基础并制定对废水的治理方案,所排放废水回收到废水收集池,被各工序使用。最终达到生产废水的循环利用、零排放。并推荐使用新的清洁工艺。

The process of sodium dichromate production and its pollution situation of waste water are introduced. Based on the process feature, the discharge spots and amount of waste water in the process are analyzed. The theoretical basis for the circulating utilization of waste water and its disposal project are drawn out. The treated waste water is discharged to the collecting pool and to be reused in sectionwise of the process. Thus, the clean process of circulating utilization and“ zero discharge”can be realized.
