摘要
以长三角地区制药企业为例,采用AERMOD模型研究了制药企业废气排放量对大气环境防护距离的影响,分析了化工园区防护距离的设定,并给出了建议。研究结果表明:①制药企业在废气达标排放的情况下,废气中的苯乙烯最大落地浓度占标率较大;②当制药企业废气量增大至10万m^(3)/h时,大气环境防护距离约250 m。
Taking pharmaceutical enterprises in the Yangtze River Delta region as an example,the AERMOD model was used to study the impact of pharmaceutical enterprise exhaust emissions on the atmospheric environmental protection distance.The setting of the protection distance for chemical industrial parks was analyzed,and suggestions were given.The research results indicate that:①Pharmaceutical enterprises have a high proportion of the maximum landing concentration of styrene in the exhaust gas to the standard when the exhaust gas meets the emission standards.②When the exhaust gas volume of pharmaceutical enterprises increases to 100000 m^(3)/h,the atmospheric environmental protection distance is about 250 m.
