摘要
应用北京师范大学水科学研究院开发的河段水质模拟工具,对未来水环境规划方案下的北京市通州区河段水质进行了模拟预测.以区内主要河段北运河和凉水河为例,分别预测了2010和2020年河段水体中的化学需氧量(COD)和氨氮(NH3-N)的质量浓度,计算结果表明,通过实行工业达标排放、建立污水处理厂及湿地生态修复,可以提高温榆河通州段水功能区水质目标,保证2020年通州区北运河出境断面水质达标.
Water quality simulation tool developed in our laboratory is applied to the main rivers in Tongzhou district, Beijing. This simulation is undertaken under the water environment regulation scheme in Beijing. The Northern Canal and Lianshui River are selected for study. Analysis of COD and NH3-N mass concentrations in the two rivers forcasted for 2010 and 2020 show that by regulating qualified industrial waste water discharge, building sewage plants and waste-water processing by wetland, prospective water quality can be improved. Discharge water quality at the outlet of the North Canal will meet national standards in 2020.
