Description

Technical Field

[0001] The utility model belongs to the technical field of comprehensive management of ecological and environmentally friendly water environments, and in particular relates to an ecological bionic water purification device for water environment management. Background Art

[0002] Water bodies can naturally reduce the concentration of discharged pollutants as time goes by as they flow downstream through physical, chemical and biological processes within the scope of their environmental capacity, which is called the self-purification of water bodies. Traditional application technologies such as artificial wetlands and riverside buffer zones are severely constrained by the space of river waters during construction, and it is often impossible to effectively treat the pollution load entering the water system through the construction of such projects alone. Therefore, the use of water purification devices with high hydraulic load, high reduction rate and small footprint can solve the above problems according to local conditions and achieve effective reduction of pollutants entering the river.
