【摘要】：以焦化废水好氧池出水为研究对象,采用微波诱导载铜活性炭深度处理焦化废水。在单因素实验的基础上,以焦化废水COD去除率为评价指标,微波功率、微波时间、催化剂用量为考察因素,采用Box-Behnken响应曲面法考察各影响因素的单独作用及交互作用对焦化废水COD去除率的影响,建立数学模型。通过响应曲面分析可知,微波功率、时间、催化剂用量以及微波功率与微波时间的交互作用对COD去除率均有显著影响,模型预测最佳工艺条件为微波功率550 W,微波时间5 min,催化剂用量20 g·L~(-1),COD去除率为84.23%,在该条件下通过两次验证实验得出结果平均值为82.63%,预测值与测定值相对误差为1.90%,两者具有较好的一致性。
[Abstract]:Coking plant wastewater was treated by microwave induced copper loading activated carbon (activated carbon) as the object of study on the effluent of aerobic tank of coking plant. On the basis of single-factor experiment, the removal rate of COD from coking wastewater was taken as the evaluation index, microwave power, microwave time and the amount of catalyst were investigated. The Box-Behnken response surface method was used to investigate the effect of individual and interactive factors on the removal rate of COD from coking wastewater, and a mathematical model was established. According to response surface analysis, microwave power, time, amount of catalyst and interaction between microwave power and microwave time have significant effects on COD removal rate. The optimum technological conditions are microwave power 550 W, microwave time 5 min, catalyst dosage 20 g / L, COD removal rate 84.23. Under these conditions, the average value of the results is 82.63 and the relative error between the predicted value and the measured value is 1.90. There is good consistency between the two.
