- 摘要:
- 双氧水是一种重要的化工产品，其在蒽醌法制备过程中会产生包含重芳烃、磷酸三辛酯、2-乙基蒽醌等有机污染物的废水。针对双氧水生产废水有机物浓度高、成分复杂、难生物降解的特点，采用重力隔油、混凝气浮、芬顿氧化、混凝沉淀、曝气生物滤池的组合工艺进行处理，介绍了主要工艺流程、主要构筑物设计参数、技术经济分析等。设计处理规模为600 m?/d，废水呈酸性（pH值=5~6），COD平均值为4 000 mg/L。近3年实际运行结果表明，COD实际处理效率达到90%以上，出水水质达到《污水综合排放标准》（GB 8978—1996）的一级排放标准。实例证明，以芬顿氧化和曝气生物滤池为核心的组合工艺能够有效处理双氧水生产废水。
- Abstract:
- The industrial production of hydrogen peroxide as an important chemical product by anthraquinone process produces wastewater containing heavy aromatics, trioctyl phosphate, 2-ethylanthraquinone and other organic pollutants. In view of the characteristics such as high organic concentration, complicated ingredients and non?biodegradable of the hydrogen peroxide production wastewater, a combined process of gravity oil separation, coagulation and air flotation, Fenton oxidation, coagulation and sedimentation, and biological aerated filter is developed to treat the wastewater. The main process, design parameters of the core units and economic analysis are elaborated for a practical project scale of 600 m3/d. The influent wastewater was acidic (pH=5-6), and the average value of COD was 4 000 mg/L. Based on the operation results in recent 3 years, the actual removal efficiency of COD was over 90%, and the effluent could meet the requirements of the first level in Integrated Wastewater Discharge Standard (GB 8978-1996). It is proved that the hydrogen peroxide production wastewater can be efficiently treated by the combined process of Fenton oxidation and biological aerated filter as core units.
