摘要
目的通过研究假单胞菌对药厂不同质量浓度含酚废水的生物降解作用,并对降解过程进行动力学分析,为实际应用提供理论依据。方法采用复合固定化的方法制作固定化细胞,使菌株更适用于工业废水处理的需要。结果从药厂废水中分离出的菌株Pseudomonas stutzeri JFL2008能够以苯酚为唯一碳源生长。降酚实验的结果表明当苯酚初始质量浓度小于1 200 mg.L-1时,其生物降解过程遵循Monod方程;当苯酚初始质量浓度大于1 200 mg.L-1时,其生物降解过程遵循Hal-dane方程。结论固定化菌株在处理含酚废水时有很好的应用前景。
Objective To study the biodegradation of phenol at different concentrations from pharmaceutical industrial wastewater by a strain of Pseudomonas and establish the dynamic equations to fit for the degradation process, in order to provide a theoretical basis for practical application. Methods Immobilized cells through the method of multi-technology of immobilization were made, so that they would be more suitable for plant wastewater treatment. Results Pseudomonas stutzeri JFL2008, which can use phenol as the sole car- bon, was isolated for pharmaceutical wastewater treatment. The results of phenol biodegradation tests sugges- ted that biodegradation of phenol could be described by Monod equation kinetically, when the initial concentration was less than 1 200 mg. L^-1. But Xvhen the initial concentration was more than 1 200 mg. L^- 1, the results of phenol biodegradation tests suggested that biodegradation of phenol could be described by Haldane equation kinetically. Conclusions Immobilized strains possess a good application potential in the treatment of pharmaceutical industrial wastewater.
