某制药厂恶臭污染环境影响研究

Study on Environmental Impact of Odor Pollution in a Pharmaceutical Enterprise

摘要: 随着城市扩张，居民区与工业企业等恶臭污染源共建现象严重，恶臭扰民问题愈发突出，评价居民是否受到恶臭污染影响是目前管理部门问题与挑战。本研究选取某制药企业为研究对象进行采样调查，并对臭气浓度进行实验室分析，在此基础上，利用CALPUFF模型进行恶臭污染模拟，分析周边敏感点的扰民影响。结果表明，该制药企业所有排气筒臭气浓度范围为131~173,780，臭气浓度较高；该企业全年小时臭气浓度最大落地点发生在厂区内，可达355，其厂界全年最大小时臭气浓度约为320，北侧敏感点全年最大小时臭气浓度为30~140之间；该企业发酵车间及污水处理站对周边恶臭影响较为严重，需进行进一步提升改造。

Abstract: At present, public odor complaint is the prominent environmental problem because the residential areas are closer and closer from industrial enterprises and other pollution sources in China. As a result, evaluating whether residents affected by odor pollution is a great challenge for envi-ronmental management department. In this study, a pharmaceutical company was selected as the research object, the sampling analysis was carried out, and the odor concentrations were analyzed in laboratory. On this basis, CALPUFF model was used to simulate odor pollution and analyze the odor impact of surrounding sensitive points. The results showed that the odor concentration of all exhaust cylinders was 131~173,780, which was very high. The highest hourly odor concentration was up to 355, which occurred in the factory. The annual maximum hourly odor concentration of factory boundary was about 320. The annual maximum hourly odor concentrations of the sensitive area were 30~140, which was in the north of the factory. What’s more, the fermentation workshop and sewage treatment station were more serious odor emission sources, which need further upgrading and transformation.
