小型肉类加工厂卫生防护距离的研究

A Study of the Hygienic Protection Zone of a Small Meat Processing Plant

作者对小型肉类加工厂周围环境中空气氨和耗氧量进行了调查。根据实测结果,结合大气扩散模式,分析了污染范围。通过实测、居民询问和扩散模式计算得到结果的综合判断,认为年产能力1500吨的肉类加工厂卫生防护距离以100m 为宜。

The situation of air NH_3 and oxygen consumption(OC)caused by pol- lution from a small meat processing plant was detected in summer and spring and the subjective responses of inhabitants in surrending areas were obtained with epidemiological investigations.The results showed that odo- ur was the main source of air pollution sent forfh from the plant.In com- parison with the results of diffusion model computation,epidemiological investigation and pollution detection,it was suggested that hygienic pro- tection zone was 100 meters from the plant with annual processing capaci- ty of 1500 Ton meat.
