摘　　要：作为一种重要的化工原料,丙烯酸(酯)年产量很大,其生产过程排放的废气量不容小觑。丙烯酸(酯)生产废水是重要的废气逸散源,以丙烯酸(酯)生产废水处理站挥发产生的废气为处理对象,设计选用生物过滤+氧化喷淋+活性炭吸附(应急)的组合工艺,处理后废气中氨、硫化氢、苯、甲苯、丙烯酸、丙烯醛、甲醛、非甲烷总烃和臭气浓度的排放浓度分别降至未检出、未检出、2.35 mg/m^3、9.24 mg/m^3、0.98 mg/m^3、1.12 mg/m^3、0.74 mg/m^3、12.2 mg/m^3和295,满足上海市《恶臭(异味)污染物排放标准》(DB 31/1025-2016)、《石油化学工业污染物排放标准》(GB31571-2015)、上海市《大气污染物综合排放标准》(DB 31/933-2015)、上海市《城镇污水处理厂大气污染物排放标准》(DB 31/982-2016)要求,实现达标排放。该联合工艺运行成本为0.0036元/m^3,运行成本低,处理效率高,可为丙烯酸(酯)生产废水站废气治理工程设计和实施提供参考。As an important chemical raw material,the annual production of acrylic acid(ester)is extremely large,and the amount of exhaust gas emitted from its production process shall not be underestimated.Acrylic acid(ester)production wastewater is an important waste gas emission source.Taking the waste gas generated by the volatilization of acrylic acid production wastewater treatment station as the object,the combined process of biological filtration,oxidation spraying,and activated carbon adsorption(in emergency)was designed and selected.After treatment,the emission concentration of ammonia,hydrogen sulfide,benzene,toluene,acrylic acid,acrolein,formaldehyde,non-methane total hydrocarbons and odor were reduced to none detected,none detected,2.35 mg/m^3,9.24 mg/m^3,0.98 mg/m^3,1.12 mg/m^3,0.74 mg/m^3,12.2 mg/m^3,and 295,respectively.The exhaust gas met the requirements of standards including Emission Standards for Odor Pollutants(DB 31/1025-2016)in Shanghai,Emission Standard of Pollutants for Petroleum Chemistry Industry(GB 31571-2015),Integrate Emission Standards of Air Pollutants(DB 31/933-2015)in Shanghai,Emission Standard of Air Pollutants for Urban Wastewater Treatment Plant(DB 31/982-2016)in Shanghai,and etc.The operation cost of the combined process was 0.0036 yuan/m^3.With low operation cost and high treatment efficiency,the process could provide reference for the design and implementation of waste gas treatment project in acrylic acid(ester)production wastewater station.
