摘　　要：随着国家对流域水质改善要求的逐渐提高,流域污染源管理变得日益重要。提出了一种基于CPNTOOLS的辽河流域畜禽养殖行业污染源仿真技术,并采用CPNTOOLS软件对辽河流域内一家典型畜禽养殖基地进行了仿真研究,经过多次仿真与数据统计分析,分别得出了该畜禽养殖基地的CODCr,BOD5,NH3-N,TP,TN日排放量的正态分布均值在90%,95%,99%置信水平下的置信区间,并结合排水量分别计算出各污染物指标排放浓度的区间。结合BAT处理技术对污染物浓度削减进行了计算仿真,并得出了处理后CODCr,BOD5,NH3-N,TP,TN排放浓度的正态分布均值在90%,95%,99%置信水平下的置信区间以及排放浓度的极大值和极小值。With the enhancement of demand tor improvement ot basin water quahty, management ot poimtant source became more important. This research proposed a CPN TOOLS-based simulation method of livestock industry in Liao river basin, and used the CPN TOOLS to run a simulation for a typical livestock enterprise in Liao river basin. After several times of simulation and statistical analysis of data,the 90%, 95% and 99% confidence intervals of mean value of normal distribution of daily water consumption （CODc~, BODs, NH3-N, TP, TN ）in livestock and poultry breeding base were obtained and the intervals of emission concentrations of pollutants were calculated with the displacement. The simulation of reduction of pollutants concentrations was executed after the BAT was studied, and the 90%, 95% and 99% confidence intervals of mean value of normal distribution of pollutants concentrations after the treatment by BAT were obtained. Also, the minimum and maximum values were obtained.
