水解-生物接触氧化工艺处理可乐生产废水

Hydrolysis-Biological-Contact-Oxidation to Treat Coke Production Wastewater

根据桂林某百事可乐饮料有限公司可乐生产综合废水水质水量特点,采用水解-生物接触氧化工艺对可乐生产废水进行处理,污水经粗细两道格栅和沉砂池、水解池之后,进入三级接触氧化池,排泥采用竖流式沉淀池,出水排入氧化塘。运行结果表明,该工艺运行管理简单,适应性较强,投资运行费用较低,运行费用仅为0.35元/m3,占地面积小,出水的各项指标均达到《污水综合排放标准》一级标准要求。

Coke production wastewater mainly consists of leakage, washery and domestic wastewater. The water quality and quantity varies sharply,but it is easy to be biodegraded. Based on these characteristics,the hydrolysis-biological-contact-oxidation method is used to treat coke process sewage. After a coarse grate and a fine grate, the sewage passes a sand basin and a hydrolysis tank, which is followed by a three-stage-contact-oxidation-pond and a vertical flow sedimentation basin. The effluent is discharged into an oxidation ditch. The operation result shows that this process is easy to manage with good adaptability, small floor area and low operating cost of only 0. 35 yuan/m^3. The effluent can reach the first grade of integrated wastewater discharge standard. It is proved that the hydrolysis-biological-contact-oxidation process is an economical and feasible method for the treatment of coke production wastewater.
