摘要：
针对某磨料磨具厂酚醛树脂生产废水的高酚醛水质特点, 采用Fenton—混凝沉淀—生物接触氧化工艺对废水进行处理。实际运行结果表明, 在进水平均COD≤10 000 mg/L, 甲醛≤1 200 mg/L时, 出水COD≤110 mg/L, 甲醛≤0.1 mg/L, 出水水质达到《水污染物排放限值》(DB 44/26—2001)二级排放标准。工程实践证明, 该工艺处理效果良好、出水水质稳定。

Abstract:
Aiming at the water quality of the wastewater containing highly concentrated phenol and formaldehyde from phenolic resin production, the wastewater has been treated by the combined process, Fenton-coagulation sedimentation-bio-contact oxidation.The results show that the effluent water quality reaches the second class discharge standard of Discharge Limits of Water Pollutants(DB 44/26—2001), under the following conditions: the average influent COD≤10 000 mg/L, formaldehyde≤1 200 mg/L, effluent COD≤110 mg/L, and formaldehyde≤0.1 mg/L.The engineering practice proves that the treatment efficiency of the process is pretty good, and the effluent water quality is steady.
