采用气升式环流反应器作为曝气装置，研究了石化废水的处理效果以及各运行参数对废水处理的影响。结果表明，气升式环流反应器可用于石化废水的生物处理，出水达到石化废水国家二级排放标准，驯化后的活性污泥出现丰富的微生物形态，降解反应过程符合一级反应动力学模型。活性污泥浓度和水力停留时间对降解反应有重要影响，存在最优操作。与传统处理相比，气升式环流反应器具有曝气效率高、处理效果好、停留时间短、占地面积小等优点，值得开展工业规模的可行性研究。
Using air-lift loop reator as aeration device,the effectiveness of treatment for petrochemical wastewater and the effect of various operation parameters to wastewater treatment are studied.The result shows,air-lift loop reator can used to biological treatment of petrochemical wastewater,the water exit reaches the protrochemical wastewater national secondary emission standard,the activated sludge after acclimated appear rich microbial morphology,the degradation reaction process accord with first order reaction kinetics model.The activated sludge concentration and hydraulic retention time has important influence to degradation reaction,and existing a optimal operation parameters.Compared with traditional treatment,the air-lift loop reactor has advantages such as high aeration efficiency,good treatment effect,short dwell time,small occupation area,etc.It is worthy of developing feasibility study of industrial scale.
