项目摘要

1. Development and validation of a non -point pollution load model considering roofs and roads as impervious surfaceRoofs and roads were considered in a non-point pollution load model as impervious surface. The importance of their different runoff characteristics was recognized in order to explain dynamic runoff behavior in an area with a separate sewer system. The runoff behavior of suspended solids was evaluated separately in two size fractions (l.2〜45μm and 45μm〜2mm). In order to fit the model simulation to the observed data, the concept of critical runoff rate for wash-off was introduced into the Sartor and Boyd model for explaining the different runoff behavior of fine and coarse particles. The simulated results with the modified Sartor and Boyd model agreed satisfactorily with the observed data for a series of seven rainfall events with weak rainfall intensities.To improve the model for better fitting of runoff behavior in heavy rains, wash-off models from pervious area were addi … More tionally proposed. Introduction of the wash-off functions for previous surface as well as the modified Sartor and Boyd model for impervious surface, the simulation results could agree with the observed data even in the heavy rainfall events.A method was developed for estimation of the fractions of roof and road surfaces in target drainages. The detailed land use data given in 10m grid basis was utilized to estimate their fractions. Once the roof and road surface fractions were given, it became easy to determine the runoff parameter values. The validity of the method was confirmed in four cities.2. Characterization of micropollutants in the dust of roof and roadPolycyclic aromatic hydrocarbons on the dust of roof and road were analyzed. The result of cluster analysis based on the profiles of the micropollutants showed a clear difference between road dust and roof dust in a district. But in the case of comparing the two districts having different pollution loading from non-traffic pollutant sources, the charasteristics of the micropollutant profile was depending much more on the characteristics of the district than the surface property.

1. 将屋顶和道路视为不透水表面的非点污染荷载模型的建立与验证在非点污染荷载模型中,屋顶和道路被视为不透水表面。为了解释具有独立下水道系统的地区的动态径流行为,认识到它们不同径流特征的重要性。在2 ~ 45μm和45μm ~ 2mm两个粒径段中分别评价了悬浮固体的径流行为。为了使模型模拟与观测数据拟合,在Sartor和Boyd模型中引入了冲刷临界径流率的概念,以解释细颗粒和粗颗粒的不同径流行为。修正后的Sartor和Boyd模式对7次弱降水事件的模拟结果与观测数据吻合较好。为了改进模型,使其更好地拟合暴雨时的径流行为,进一步提出了透水区冲刷模型。通过引入以往地表的冲刷函数和改进的不透水地表Sartor和Boyd模型,即使在强降雨条件下,模拟结果也能与观测数据吻合。提出了一种估算目标排水系统中屋顶和路面分量的方法。利用10米格点基础上给出的详细土地利用数据估算其分值。一旦给出了屋面和路面分量,就很容易确定径流参数值。该方法的有效性在四个城市得到了验证。分析了屋顶和道路粉尘中微量污染物的特征,分析了屋顶和道路粉尘中的多环芳烃。基于微污染物分布特征的聚类分析结果表明,某地区道路扬尘与屋面扬尘存在明显差异。但在非交通污染源污染负荷不同的两个区域对比中,微污染物剖面特征更多地取决于区域特征而非地表性质。少
