平原感潮河网地区边界水闸常规引清调水对内河水质影响分析

Analysis of the Impact of Normal Water Diversion on the Water Quality of Plain Tidal River Networks

采用MIKE11商业软件构建浦东水利片水动力模型和污染物对流扩散模型,在一年的四个季度中,分别选取平均潮差最大月份的一个潮汐过程(初三到初十八)。假定内河水质初始状况为劣V类,不考虑点、面源污染加入,仅通过水闸常规引清调水,不考虑降雨和水体自净能力,计算该过程中内河水质变化,统计浦东新区39个考核断面(本次研究不考虑位于滴水湖的断面)中水质能达到V类的断面数。

Using MIKE11 software, a river network model and a advertising-diffusion model established by the Numerical method. Based on the model, the water quality of plain tidal river networks which simply improved the water transfer project was simulated, ignoring the effect of rainfall, water self-purification ability, and point and non-point source pollution. The periods of simulation were four tidal processes from four quarters, which was in the biggest mean tidal-range month. ,assuming the initial water quality was worse than Grade V. On the base, the amount of sections the water quality of which was up to Grade V of 39 water quality assessment sections ,was counted..
