典型农用地降雨径流污染物输出特征
Characteristics of Pollutant Output in Farmland Runoff from Simulated Rainfall
摘要
Abstract
The output characteristics of pollutants in farmland runoff under different artificial rainfall intensity was researched at typical farmland in Changshu suburban area.The contribution of runoff pollution to the river pollution was also discussed.Result revealed that 1 )the maximum concentration of pollutant appeared at the beginning of the rainfall under small intensity,while emerged later under big rainfall intensity;2)the summation of TN and CODMn outputs were far larger than the output of TP and ammonia nitrogen,also the summation of pollutant in-creased with the increase of rainfall intensity but the change was nonlinear;3)TN and TP had a greater contribu-tion to the river contamination.关键词
