【摘要】 针对实际焦化废水生化出水,进行了芬顿氧化深度处理加药策略和流化床工艺应用研究。首先通过单因素实验,确定了3个主要影响因素p H、Fe²⁺和H₂O₂投加量的取值范围。随后用响应曲面分析方法进行了三因素三水平的加药策略设计及实验,以COD去除率为响应值,建立了加药策略与焦化废水COD去除率间的预测关系模型。发现在最优和最经济条件下,模型预测值与实际值均非常接近,证实模型稳定可靠。并进行了连续式芬顿流化床应用研究,废水中COD去除率（55%）优于传统芬顿方法（40%）。该工艺可同步高效去除溶解性总铁（>60%）,产生的Fe³⁺大部分结晶/附着于流化材料表面。结果表明,芬顿流化床是一种经济高效的水处理高级氧化技术,具有较好的应用潜力。更多还原

【Abstract】 Response surface methodology（RSM） was used to simulate the advanced Fenton treatment of a coking wastewater.Three important influence factors, i.e. p H, Fe²⁺and H₂O₂ dosages, was evaluated for the removal of COD. It indicated that the Fe²⁺dosage is the most important factor, while the model-optimized condition could be obtained. 55 % removal of COD was achieved accordingly under the condition, which was very consistent with the related model-predicated COD removal. Anoth-er i.e. the most cost-effective condition was also verified successfully for its removal of COD in coking wastewater. Further-more, a fluidized-bed Fenton process was applied for the advanced treatment of coking wastewater based on this condition.55% of COD removal was obtained, which was better than that achieved in the corresponding traditional Fenton process. In-terestingly, simultaneous removal of ferric ion was also observed. SEM analysis of the original/reacted fluid materials suggest-ed the production of [Fe（OH）₃] on the surface.更多还原
