A Study on the Key Monitoring Techniques and the Analysis of the Results in Odor Source Boundry Air Taking a Large Scale Garbage Landfill in Xi'an for Example

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.
