超大型垃圾中转站恶臭预测及工艺分析

Stench effect prediction and process analysis of ultra large life waste transfer station

超大型生活垃圾中转站的污染控制要求高,对其污染源的分析、环境影响预测及各种污染控制措施也区别于以往中小型垃圾中转站。文章以日处理垃圾量达到1000t的合肥市某超大型中转站为个案,重点预测超大型中转站对大气环境的影响,采用导则推荐的Screen3Model估算模式定量计算恶臭源强,结合恶臭强度定级等方法,与同类型中转站进行对比分析,提出可行的微生物和植物液组合式脱臭除尘处理工艺污染对策,为同类型超大型生活垃圾中转站工艺设计和污染控制提供参考。

Ultra large waste transfer station has a high demand of pollution control .The pollution sources anal-ysis ,environmental impact prediction and pollution control measures of the ultra large waste transfer station are different from those of the medium and small waste transfer stations .Taking an ultra large waste transfer station with a daily disposal amount of 1 000 t in Hefei City as an example ,the effect of the ultra large waste transfer station on atmospheric environment is forecasted . The Screen3Model estimation model and odour strength grading method are used to calculate stench pollution source strength ,and the result is compared with that of the transfer station of same type .The feasible microorganisms and plants fluid combined deodori-zation process is put forward to provide a reference for the process design and pollution control of the ultra large life waste transfer station of same type .
