苏南河网水体污染控制工程及其效果分析

Project of Pollution Control and Its Effect Analysis on River Network of South Jiangsu Provine

以武进港流域的跃进河、陈巷浜、西大河浜为例,开展了河网水体污染控制技术研究。在河道中分别实施生态修复技术,缓流纳污河浜原位增氧—动态生态组合工艺处理农村生活污水技术(ODBP)工艺及ET生化与生态系统组合处理工艺,对3个示范工程的运行效果进行了分析比较,研究了适用于流域河网地区的污染控制技术。负荷削减效果分析表明,3种工艺技术对水中氮、磷等污染物质的去除效果均较好,并具有良好的生态景观效果。通过进一步优化,可形成适合于太湖流域河网地区的水环境质量改善和生态修复的关键技术。

As the pollution control project carrying out in the drainage network of branches Yuejinhe, Chenxiangbang, and Xidahebang of Wujingang River, the pollution control technology was explored and researched by applying ecological restoration technics, ODBP for rural house-hold wastewater, combination ecological treatment（ET） of biochemical and ecological systems respectively in the three rivers. Comparing the treat- ment effects of three pilot projects, the pollution control techniques suitable for the area with drainage net- work were established. The effects demonstrated that the three techniques can effectively remove the nitro- gen, phosphorus and other pollutants in the water with good ecological landscape. After further study and technical optimization, it can become a key technology applied in the improvement of the environment and ecological restoration in the similar area of Taihu Lake basin.
