A biologically enhanced three-dimensional landscape constructed wetland system

Abstract

The invention discloses a biologically enhanced three-dimensional landscape artificial wetland system. The biologically enhanced three-dimensional landscape artificial wetland system is of a three-dimensional structure, and comprises an overflow pool, an overflow weir, guide plates, a water outlet channel, a water pump, a water pipe, a purification layer and a grating; the purification layer comprises an artificial wetland and a biological ball purifying area, and at least one purification layer is arranged; the grating is arranged on one side of the purification layer; the overflow pool is located at the top end of the three-dimensional structure; the water pump is connected with the overflow pool by use of the water pipe; the overflow weir is arranged on one side of the overflow pool; the guide plates are arranged to surround the overflow weir and connected with the next purification layer; the bottommost purification layer is connected with the water outlet channel. The biologically enhanced three-dimensional landscape artificial wetland system is integrated with artificial wetland purification, biological ball enhanced treatment, drop aeration, seepage-proofing and visual beauty; a plurality of such systems can be connected in parallel or in series to operate, and therefore, the treatment efficiency of the artificial wetland is greatly improved and the floor area of the artificial wetland is reduced to a certain extent. The biologically enhanced three-dimensional landscape artificial wetland system can be widely applied to the fields of domestic sewage treatment in vast rural areas, sewage plant tail water deep treatment and the like.

Description

technical field [0001] The invention relates to the field of artificial wetlands, in particular to a biologically enhanced three-dimensional landscape artificial wetland system. Background technique [0002] Constructed wetland system water purification technology is a new type of sewage and wastewater treatment technology developed in the 1970s and 1980s. It is defined as a composite of saturated substrates, emergent and submerged vegetation, animals and water bodies designed and constructed artificially. body. At present, there are three types of constructed wetlands: surface flow constructed wetlands (SFW), subsurface flow constructed wetlands (SFS) and vertical flow constructed wetlands (VCW). Among them, subsurface flow constructed wetlands are the most widely studied and applied types in various countries. [0003] Constructed wetland has the characteristics of low investment, low energy consumption, large buffer capacity and simple process, and has been widely used a...

Problems solved by technology

For example, CN102126794A announced the artificial wetland system of free falling water and oxygenation, which is composed of stepped multi-level artificial wetlands. Using free falling water for aeration and oxygenation solves the problem of aeration to a certain extent, but it has high requirements on terrain and The treatment efficiency of the entire constructed wetland needs to be improved
