【摘要】 里下河地区是有名的“锅底洼”地区，西有京杭大运河、东有通榆河两条南水北调的清水通道。随着苏北地区工业化进程的加快，该地区尾水面临出路问题。本论文在资料收集、现状调查和查阅文献的基础上，对里下河地区的兴化市、高邮市和宝应县的水环境现状进行了评价，并结合污染源预测，对该地区水环境容量可利用性进行了分析。在此基础上，通过对尾水通道、深度处理、尾水资源化利用等方案的研究和论证，提出研究区的尾水处理方案。论文主要研究成果如下：(1)对研究区内水环境质量现状进行分析，结果表明研究区内河道监测断面有42.9％达不到功能区目标要求。对研究区域水环境容量的计算及其规划年污染源预测表明，规划水平年排水河道无剩余水环境容量。(2)通过对深度处理、尾水资源化利用、尾水专道排放等方案的可行性论证，对各种尾水处理方案的工程投资估算及环境经济分析加以比选，提出了建立尾水通道、引入人工湿地处理系统进行生态处理、处置后出水进行资源化综合利用的区域尾水处理方案。更多还原

【Abstract】 Lixiahe district, the famous "pan bottomland", is surrounded by two clean water channel way for south-north water transfer project. As the speedup of industrialization in northern Jiangsu province, the outlet of tail water become a difficult problem. Based on data collection, inventory survey and literature search, the existing water environment of xinghua city, gaoyou city and baoying county was assessed and the water environment capacity was calculated also. After comparison and demonstration among different processing methods include tail water channel way, advanced treatment and supplement as water resource, the process scheme of tail water is presented in the paper. The main conclusion was as follows:(1) The result of assessment of water environment showed 42.9% of water quality monitoring sections could not reach the standard. The main rivers which received waste water have not capacity for now(2005) and in the future(2010).(2) Base on comparison and demonstration of different methods, the process scheme of tail water is presented: first constructing channel way to admit tail water, then treating tail water by constructed wetlands, and the worked water can used as supplement of water resource. The budgetary estimates and environment economics analysis of different processing schemes were also displayed.更多还原
