水质监测数据时间序列的时域和频域分析
Analysis of Time Domain and Frequency Domain of Water Quality Monitoring Data in Time Series
摘要
Abstract
Taking the average daily values of CODMn ,NH3 -N,TP and TN of 5 sections of water quality automatic monitoring in a certain river in 2010 for study objects,this paper applied time domain and frequency domain analysis methods in the time series analysis of pollutant concentration. Combined with the variation rule of the sectional average monthly pollutant concentration and the wavelet analysis,this paper revealed the 10 days periodic activity of main pollutants in several water quality monitoring sections.关键词
