生物电Fenton系统对餐饮含油废水处理研究

Research on the treatment of catering oil-bearing wastewater by the bioelectro-Fenton system

利用生物电Fenton系统对某高校食堂的餐饮含油废水进行处理,探讨了系统对餐饮含油废水的处理性能,考察了温度、阴极液初始pH和阴极曝气量等因素对系统性能的影响,并进行了工艺条件优化。结果表明,系统运行的最佳工艺条件:温度35℃,阴极液初始pH=3,阴极曝气量0.2 L/min。在最佳工艺条件下,阳极COD去除率、阴极油去除率和输出电压分别达到91.1%、95.3%和431.9 m V。

The bio-electro-Fenton system has been used for the treatment of catering oil-bearing wastewater from a college dining hall. The treatment effects of the system on the catering oil-bearing wastewater are discussed ,the influences of factors,including temperature,catholyte initial pH,cathode aeration rate,etc. investigated,and technological conditions optimized. The results show that the optimum conditions for the system operation are as follows：the temperature is 35 ＆#176;C,catholyte initial pH 3 and cathode aeration rate 0.2 L/min. Under optimal condi-tions,the anode COD removing rate,cathode oil removing rate and output voltage are 91.1%,95.3%and 431.9 mV, respectively.
