摘要:
针对油系针状焦废水含油高、含硫高、水质波动大、可生化性差的特点，采用“隔油+调节+脱硫+气浮+A/O生化+改良型Fenton”组合工艺，设计了处理规模为1 920 m3/d的废水处理工程，介绍了工艺流程、主要设计参数及对主要污染物的去除效果。实际运行结果表明，该组合工艺处理油系针状焦废水具有处理效果好、抗冲击能力强、运行稳定性好的特点。在进水COD、NH3-N、TN、TP平均浓度分别为4 360、75、186、12 mg/L的情况下，处理出水平均浓度相应为65、2.5、12、0.5 mg/L，稳定达到《污水综合排放标准》（GB 8978—1996）的三级标准及园区综合污水厂协议标准。
Abstract:
Aiming at the characteristics of high oil and sulfur content, high quality fluctuation and poor biodegradability of oil-based needle coke wastewater, a combined process of oil separation, regulation, desulfurization, air flotation, A/O biochemical treatment, and modified Fenton oxidation is used to design a wastewater treatment project with 1 920 m3/d. The process flow, main process design parameters and the removal effect of main pollutants are introduced. The operation results show that the combined process has high efficiency, strong impact resistance and good operation stability. When the average influent concentrations of COD, NH3-N, TN, TP are 4 360 mg/L, 75 mg/L, 186 mg/L and 12 mg/L, the average effluent concentrations of those are 65 mg/L, 2.5 mg/L, 12 mg/L and 0.5 mg/L, respectively, which stably meet the level Ⅲ criteria of Integrated Wastewater Discharge Standard (GB 8978-1996) and the comprehensive sewage plant agreement standard requirements in the industrial park.
