【摘要】 通过调查松柏山水库的各类污染源及现状水质,分析水库水体的污染情况。依照各类污染物的排放系数,并结合水库周边的实际情况得出入河系数,计算得出松柏山水库流域污染物COD、NH3-N、TN和TP入河排放总量分别为318. 81 t/a、27. 7 t/a、137. 63 t/a、26. 8 t/a。从污染物类型来看,松柏山水库流域内COD污染贡献率最大的污染源为城镇生活源,污染贡献率为53. 47%; NH3-N污染贡献率最大的污染源为城镇生活源,贡献率为93. 93%; TN和TP污染贡献率最大的均为农业面源,贡献率分别为69. 14%和81. 88%。基于此提出防控措施,为保护松柏山水库水质提供技术支撑。更多还原

【Abstract】 By investigating the various pollution sources and current water quality of the Songbaishan Reservoir,the pollution of the reservoir water quality is analyzed. According to the emission coefficient of various pollutants,combined with the actual situation around the reservoir,the coefficient of entering the river is obtained. It is calculated that the total amount of COD,NH3-N,TN and TP discharged into the Songbaishan reservoir basin is 318. 81 t/a. 27. 7 t/a,137. 63 t/a,and 26. 8 t/a.From the perspective of pollutant types,the pollution source with the highest contribution rate to COD(53. 47%) and to NH3-N(93. 93%) is both from urban living source; The largest contribution rate to TN and TP(69. 14% and 81. 88%,respectively) is from agricultural non-point source.Based on this result,the prevention and control measures are proposed to provide technical support for protecting the water quality of the Songbaishan Reservoir.更多还原
