摘　　要：酚醛树脂工业废水中含有高浓度苯酚和甲醛等污染物,针对废水特点,某酚醛树脂生产企业采用回收酚醛树脂+生物处理+深度氧化处理的组合工艺对其进行处理,同时采用碱液喷淋+生物除臭工艺处理废水处理过程中产生的含苯酚、甲醛等污染物的废气。该系统已稳定运行3 a,运行结果表明,采用的处理工艺能显著去除废水中的苯酚和甲醛,处理后苯酚和甲醛的排放质量浓度分别低于0.5 mg/L和5 mg/L,满足《合成树脂工业污染物排放标准》(GB 31572—2015)间接排放标准和《污水综合排放标准》(GB 8978—1996)约定的水质要求。此外,废气监测结果显示,甲醛、酚类、非甲烷总烃、氨等均满足当地环保要求。该处理工艺具有去除效率高、工程投资少和运行费用低、处理效果稳定等特点,能广泛应用于酚醛树脂工业废水的治理。The wastewater generated by the phenolic resin industry contains high concentrations of pollutants such as phenol and formaldehyde.Based on the characteristics,a certain phenolic resin production enterprise adopted a combination process of recycling phenolic resin,biological treatment,and deep oxidation treatment to treat the wastewater.Meanwhile,alkaline spray and biological deodorization process was used to treat the waste gas contain-ing pollutants such as phenol and formaldehyde generated from wastewater treatment.The system had been in stable operation for 3 years,and the operating results showed that the adopted treatment process could significantly remove phenol and formaldehyde from wastewater.The emission concentrations of phenol and formaldehyde after treatment were less than 0.5 mg/L and 5 mg/L,respectively,which met the indirect discharge standards in the Emission Stan-dard of Pollutants for Synthetic Resin Industry(GB 31572-2015)and the water quality requirements in the Inte-grated Wastewater Discharge Standards(GB 8978-1996).In addition,the exhaust gas monitoring results showed that formaldehyde,phenols,non-methane total hydrocarbons,ammonia,etc.met local environmental protection require-ments.This treatment process had the characteristics of high removal efficiency,low investment and operating costs,and stable treatment effect,which could be widely used for the treatment of phenolic resin industrial wastewater.
