Comprehensive technology for ecological restoration of low-pollution river water

The invention discloses a comprehensive technology for the ecological restoration of low-pollution river water. The technology constructs the low-pollution river water environment comprehensive control engineering treating flowing water as a base, treating ecological restoration as a core and giving consideration to the landscape improvement through the integration and optimization of ecologic restoration combination techniques comprising a water power control technique, a polluted basement restoration technique, an underwater microtopography shaping technique, an aquatic plant recovery technique, an aquatic animal restoration technique, an aquatic life reinforcement technique, a water landscape construction technique and the like. The comprehensive technology has a good pollutant removal performance, and the TN, NH3-N and TP reductions reach 75.5%, 84.5% and 92.0% respectively.
