A novel integrated process of coagulation and adsorption was proposed for the advanced treatment of biologically pretreated coking wastewater. Results of laboratory, pilot, and industrial-scale experiments indicated that this one-step novel process can remove biorefractory pollutants, achieving the maximum chemical oxygen demand (COD) and cyanide removals of around 85.3% and 99.4%, respectively. Its effluent could meet the corresponding discharge standards without any further treatment, i.e., COD <30mg/L, cyanide <0.1mg/L, and improved effluent safety (lower toxicity). The easy operation and high efficiency of this method reflect its engineering-application potential in the tertiary treatment of coking wastewater.
一种新型的混凝吸附一体化工艺被提出用于焦化废水的深度处理。实验室、中试和工业规模实验的结果表明,该新工艺可以去除生物难降解污染物,最大程度地去除化学需氧量(COD)和氰化物,分别达到约 85.3%和 99.4%。其出水无需进一步处理即可达到相应的排放标准,即 COD<30mg/L,氰化物<0.1mg/L,提高了出水的安全性(毒性降低)。该方法操作简单、效率高,反映了其在焦化废水三级处理中的工程应用潜力。
