摘　　要：苯酚作为一种重要化工原料,因其具有消毒、杀菌、局部麻醉和助消化等功能而被广泛地应用于诸多领域。不同苯酚含量的废水作为这些工业的废物被排放到环境中,从而导致空气或水中的苯酚浓度升高。为了评估酶对酚质量分数低于5%的工业废水的苯酚去除能力并优化反应条件,研究了漆酶和过氧化物酶两种不同的酶对苯酚的去除能力,采用响应面法(RSM)优化了酶促反应条件。结果表明:漆酶对苯酚的去除率达到78%。在固定化酶的研究中,达到了50%的去除率。As an important chemical raw material,phenol is widely used in many fields because of its functions of disinfection,sterilization,local anesthesia and digestion aid.Wastewater with different phenol contents is discharged into the environment as waste from these industries,thus increasing the possibility of increasing the concentration of phenol in the air or water.In order to evaluate the phenol removal ability of enzymes in industrial wastewater with a phenol mass fraction below 5%and optimize reaction conditions,the phenol removal ability of laccase and peroxidase was studied.Response surface methodology(RSM)was used to optimize the enzymatic reaction conditions.The results showed that the removal rate of phenol by laccase was 78%.In the study of immobilized enzyme,the removal rate of 50%wasachieved.
