农业主要面源污染物迁移转化特征分析
Analysis on the Characteristics of Transportation and Conversion of Major Agricultural Non-point Source Pollutant
摘要
Abstract
[Objective] This research aimed to study the characteristics of transportation and conversion of major agricultural non-point source pollutant in surface water. [ Method ] Field experiments were arranged according to different nitrogen and phosphorus fertilizer and irrigation in Qianguo Irrigation Area. Then water samples at different points were obtained to investigate the contents of ammonium nitrogen, niter nitrogen, phosphate and chemical oxygen demand. [ Result ] The results showed that there was only one peak when ammonium concentrations waved. While there were several peaks when niter nitrogen concentrations waved during the whole growth period of rice. The changing of phosphate concentration of different levels drainage system showed a consistent trend. The changing process of chemical oxygen demand and dissolved ox-ygen concentration appeared a negative correlation. [ Conclusion] This research could provide surpports for regional joint control of water quality and quantity.关键词
