Abstract
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.
