Fenton试剂法处理炼油污水的影响因素研究

Study of Treatment to Refinery Wastewater by Fenton Chemical Means

以炼油废水的化学需氧量(COD)去除率为考察点,研究了催化剂(Fe2+)、氧化剂(H2O2)、光照时间和光照强度等因素对炼油污水中COD去除率的影响,并且通过正交实验,对COD的降解工艺进行了优化组合。结果表明:当Fe2+加入量为3 g/L,H2O2用量为0.18 mL/mL,光照时间为2h时,COD值去除率达到97%以上。

The treatment conditions of the refinery wastewater were discussed by the single factor experiment, and the optimum treat conditions were determined by orthogonal test. The result was indicated, the optimum degradation conditions were ：the COD removal ratio of refinery wastewater could reach over 97% ,under the condition of 400W metal halide lamp,2 h of illumination time, 3 g/L of Fe2 ＋ usage, and 0.18 mL/mL of n2 02 usage.
