垃圾堆肥场堆肥废气环境影响评价分析

Case of Environmental Impact Assessment for Composting Waste Gas in the Site of Refuse Composting

垃圾堆肥场的建设将改变目前垃圾任意堆放的局面 ,堆肥产品可用于林业使垃圾得到无害化处理 ,并变废为宝。尽管如此在垃圾堆肥过程中还将释放出有害气体和垃圾渗透液等影响环境质量。针对堆肥所产生的大气污染物进行源强确定、扩散计算 ,分析其影响范围并推算卫生防护距离。

The construction of the site of refuse composting will change the present situation where the refuse is placed anywhere. However,when composting product is applied into forestry, refuse will be disposed without harm and become valuable materials.However,the harmful gas and leachate produced in the course of refuse composting will affect the regional environmental quality. In the paper, four aspects of atmospheric pollution are discussed and predicted: determination of discharge amount,calculation of diffusion model, influence area and health protective distance.
