摘要
对2011年秦皇岛市农业污染源进行分析并测算各污染物排放量,结果表明,农业面源COD排放量为38 768.27 t,NH3-N为7 593.71 t,TN为15 684.63 t,TP为7 821.18 t;昌黎县是秦皇岛市农业面源污染最重的污染区域;农村生活源对COD排放量的贡献率最大,种植业对NH3-N、TN和TP排放量的贡献率最大。
This paper analyzed the agricultural pollution source of Qinhuangdao in 2011 and calculated each pollutant emissions. The research results showed that the COD, NH3-N, TN, TP emission were 38 768.27 t, 7 593.71 t,15 684.63 t and 7 821.18 t. Agricultural non-point source pollution of Changli county was the more serious pollution area in Qinhuangdao. The COD contribution rate in rural life was the biggest, the NH3-N, TN, TP contribution rate in planting was biggest.
