摘要
Abstract
A typical sewage treatment plant in northern China was taken as the research object.Through sampling,odor index detection,and artificial olfactory methods,the pollutants that produced odors were identified.According to the characteristics of the plot,the transformation process of pollutants was analyzed in depth,with the source and formation mechanism of odor substances clarified.The results show that ammonia gas is the substance that produces odors in this plot.It occurs because the soil in the plot is alkaline.The sewage with excessive ammonia nitrogen leaks into the soil,leaving a large amount of free ammonia and ammonium ions in the soil.Under alkaline conditions,the ammonium ions are converted into free ammonia,which then volatilizes into the atmosphere in the form of ammonia gas and causes odors.Based on chemical detection and analysis of soil samples,this study introduces artificial olfactory identification methods for identifying odor substances and combines them with the transformation process of pollution indicators in different environments for comprehensive analysis.It provides a new method and idea for analyzing the source of odors in sewage treatment plant plots.关键词
