恶臭源厂界空气中恶臭物质监测技术要点及结果分析探讨——以西安市某大型垃圾填埋场为例

摘要

The paper established the standard curve using salicylic acid - sodium hypochlorite method for analysis of ammonia. We explored the analysis method of ammonia gas in odor pollutants by the way of field monitoring around the landfill. At the same time, we made some analysis of the dynamic relationships among odor concentration, sulfuretted hydrogen, ammonia. An initial feasible way was identified to determinate ammonia sample for the garbage landfill. The leachate sewage treatment station and its downstream area were main points where the odor generated in the landfill. The odor gas pollution diffused from non - point source instead of point source.%建立了水杨酸-次氯酸钠法分析氨的标准曲线,通过对西安市某垃圾填埋场的实地监测,探索了恶臭气体中氨气的分析方法.分析了臭气、氨气、硫化氢之间的浓度相关性,利用本次监测数据,找出了针对该垃圾处理场的高浓度氨气样品初步分析方案.恶臭产生的主要点位为垃圾场渗滤液污水处理站及下游区域,垃圾场臭气呈现出由点源污染(作业面)到面源污染扩散的态势.
