摘要
采用铁碳内电解法预处理焦化厂焦油车间综合废水,通过分析铁碳质量比、反应溶液pH值、反应时间及反应温度等条件对COD脱除率的影响,确定该废水处理法的最佳反应条件。试验结果表明,在常温条件下,铁碳质量比为6∶1、反应溶液pH值为3.0、反应时间为40min时,内电解法处理废水的COD脱除率为25%~26%。
Wastewater from coal tar workshorp of coking plant was treated by Fe-C inner electrolysis. To find the optimum reactive conditions for the treatment, influences of rn（Fe）/m（C）,pH of the reaction solution, reaction time and reaction temperature on COD removal rate were analyzed. Experimental results show that COD removal rate could reach to 25 %--26 % under the conditions of 6：1 of m（Fe）/m（C）, 3.0 of pH, 40 min of reaction time and room temperature.
