Method for constructing wet land park type ecological water purification system

The invention belongs to the technical field of environmental engineering water treatment, and in particular relates to a method for constructing a wet land park type ecological water purification system. The method comprises the steps of: pretreatment of influent water by a polluted water pretreatment system, further purifying treatment of influent water quality by an ecological purification system, beautification and modification of a water body by a landscape lake wet land system, further degradation of water pollutants and final outlet of water reaching the standards into a river. The method provided by the invention combines a non-ecological water quality purification technology and an ecological water quality purification technology, and is a method with treatment in accordance with local conditions and free combination of design technologies. The method not only can ensure the purifying effect on water quality, but also has good ecological landscape effect, entertainment function and environmental education function, thereby effectively solving the problem of instable treatment effect of polluted water at present, lowering the system operating cost, and simultaneously constructing landscape and beautifying environment in the process of pollutant treatment.
