中文摘要: 在进行监测时要求监测采样断面的污染物分布均匀。污染物分布均匀与否受河流环境水文特征、污染物排放方式、河流污染物背景浓度等因素影响。为保证在排污口下游监测断面的污染物分布均匀,模拟采用平面2维水质数学模型,通过对上游排污方式这唯一可以人为控制的因素进行反演和优化,从而确定最优排污方式,使下游监测断面的污染物分布状况满足监测采样的要求。结果表明,在不同背景情况下,3孔排放方式均能使污染物在监测断面分布均匀,满足监测采样要求。
Abstract:The basic demand of the monitoring and sampling was that the contamination was distributed uniformly,while the contamination was distributed uniformly or not was affected by the circumstance hydrology characteristic,the draining manners,and the background concentration of the river,etc. For meeting the demands of the monitoring and sampling, the plane planar water quality model was applied into the reverse deduction and the optimization of the draining manner. The results showed that the tri-limber hole draining manners is the optimal.
