Embodiment 1

[0029] This example is a deep purification project for the tail water of a sewage treatment plant in a certain area in the north. The influent water quality refers to the pollutant concentration data of the first-class A discharge standard of urban sewage, and the effluent water quality refers to the Class IV water of the surface water environmental quality standard. The treatment of this embodiment Capacity is 40000m 3 / d, the comparison table of inflow and outflow water quality is as follows:

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering water treatment, and in particular relates to a construction method of a wetland park type ecological water purification system. Background technique [0002] The wetland park is a public welfare ecological park with multiple functions such as wetland protection and utilization, popular science education, wetland research, ecological sightseeing, leisure and entertainment. Wetland parks have played an important role in protecting biodiversity, maintaining fresh water resources, regulating climate, degrading pollutants, providing production and living resources for human beings, and developing urban tourism. Ecological water purification technology started earlier in foreign countries, and the technology is relatively mature. The U.S. National Environmental Protection Agency is currently vigorously developing the ecological water treatment database and local database in North Amer...
