摘要
利用微孔气体分布器对石化工业废水进行活性污泥曝气 ,并和传统曝气池进行了对比。考察了温度、气速、初始CODCr浓度和反应器结构 (鼓泡塔和环流塔 )对这种废水生物降解过程的影响。结果表明 ,微孔塔式曝气与传统的曝气池相比 ,具有降解时间短 ,占地面积小 。
The treatment of petrochemical wastewater was studied in a column reactor with a porous gas distributor.The results indicated that the column reactor possesses of obvious advantages over the traditional aeration pool in terms of high efficiency.The effects of temperature,gas velocity,and initial COD Cr concentration and reactor configuration on the wastewater treatment were investigated.It can be shown by the experimental results that the degradation of the organic compounds in the wastewater was promoted in a suitable temperature range,and raising gas velocity could accelerate the reaction rate.
