针对浑河沈阳—抚顺（沈抚）区域重污染支流污染来源及水质变化特点，优化筛选出潮汐流人工湿地强化脱氮技术、多层组合生物浮岛净化技术，以及傍河藻类塘与水生植物塘联用等支流河修复技术；分析了各项技术的基本原理、处理效果，提出了最佳工艺运行参数，验证了技术在示范工程中的应用效果。结果表明，相关技术对于北方地区重污染支流具有较好的治理效果，具有较高的推广价值。

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 technology 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.
