不同温度和pH值对含酚废水生化处理效率的影响

Effect of Temperature and pH on the Biochemical Treatment of Phenol Containing Wastewater

含酚废水主要来源于煤气、焦化、石油化工、木材加工、有机合成农药、油漆等多种工业中,一般测定多为测定挥发酚含量,各种酚统一按苯酚（C6H5OH）的含量表示。酚类属有机有毒物质,含酚废水对于环境的危害很大,水体遭受酚污染后,严重影响各种水生生物的生长和繁殖;对于人类的危害,主要是作用于神经系统。

Temperature and pH are two main factors effect microbic degradation of phenols. Microbe and enzyme require a suitable range of temperature and pH. Results of experiments show that microbic degradation of phenols is most effective at 35℃ and pH 6.
