摘要
国家"十一五"期间,辽河流域水污染治理取得了突破性进展,实现了流域干流水质化学需氧量(COD)消灭劣V类的目标。为了巩固辽河干流治理成果,实现可持续发展的长远目标,辽宁省划定了辽河保护区,成立了保护区管理局,这是国内成立的第一个以流域综合管理为目标的行政机构,并进行了辽河保护区治理与保护研究。本研究以建设防洪安全、水质良好、生态健康、景观优美的健康河流生态系统为出发点,融合了水利学、生态学、环境学、景观学、经济学等多学科交叉理念,统筹考虑水利工程、污染治理工程、生态修复工程、示范区建设工程等项目的相互影响及关系,分别进行了土地利用、生态系统修复、河道综合治理、生态示范区建设、治理与保护能力建设5个方面的研究。
The novel remediation technologies for heavily polluted river in Shenyang--Fushun Section of Hunhe River basin were adopted according to their wastewater sources and water quality characteristics. The tech- nology and effects of strengthened tidal-flow wetland for nitrogen removal, the multi-layers biological floating inland, and the combined process of algal pond and hydrophytes pond were optimized. The principal of removal theory, removal effect and optimal operation parameters were analyzed. Additionally, their practical treatment capability was proved through real demonstration project. The result shows that the selected process displays a good treatment capability and applicability for northern polluted river.
