Abstract:

The design and operation of a coagulation deposition-biological contact oxidation process for treating whet wastewater is introduced. The design size is 48 m³/d. The average COD_Cr of inlet wastewater is 3 540mg/L, the highest value is 10 100mg/L. The continuous operation results show that the average COD_Cr of outlet water is 49mg/L, the highest value is 66mg/L, and the other water quality parameters meet the discharge standard. It shows that this process has a better pertinence to this kind of whet wastewater. It meets the design requirement.

Key words: whet wastewater, coagulation deposition, biological contact oxidation

摘要：

介绍了采用混凝沉淀-生物接触氧化工艺处理研磨废水的设计和运行情况。该项目设计规模为48 m³/d，进水COD_Cr平均为3 540mg/L，最高达10 100mg/L。连续运行表明，出水的COD_Cr平均为49mg/L，最高为66mg/L，其余指标均达到相关标准。表明该处理工艺对研磨废水具有较好的针对性，达到了设计要求。
