Embodiment 1

[0034] This embodiment provides an assembled wetland device, such as Figure 1 to Figure 3 As shown, at least one wetland unit module 1 is included, and the wetland unit module 1 includes a support frame 11 and a packing unit 12 located within the support frame 11 . Water distribution units are respectively formed on the four side plates and the bottom plate of the support frame 11 , and a water distribution assembly is formed on the top of the support frame 11 . So that the wetland unit module 1 forms various water flow channels that can correspond to the upward vertical underflow, the downward vertical underflow or the horizontal underflow. According to the invention, by arranging water distribution units on the four side plates and the bottom plate of the support frame and disposing water distribution components on the top, free infiltration in multiple directions can be realized, so as to form a multi-mode corresponding horizontal undercurrent, upward vertical undercurrent...

Embodiment 2

[0045] This embodiment provides another assembled wetland device, such as Figure 4 to Figure 8 As shown, at least one wetland unit module 1 is included, and the wetland unit module 1 includes a support frame 11 and a packing unit 12 located within the support frame 11 . Water distribution units are formed on the four side plates and the bottom plate of the support frame 11, respectively, and a water distribution assembly is formed on the top of the support frame 11, so that the wetland unit module 1 forms a water distribution unit that can correspond to the upward vertical underflow, the downward vertical underflow or the horizontal underflow. Multiple modes of water flow channels. In the present invention, by arranging water distribution units on the four side plates and the bottom plate of the support frame and disposing water distribution components on the top, free infiltration in multiple directions can be realized to form a multi-mode corresponding horizontal undercurre...

Embodiment 3

[0057] This embodiment also provides a wetland system, including the assembled wetland device described in Embodiment 1 or Embodiment 2, and also includes a water inlet device and a water outlet device. Preferably, the water inlet device includes a water inlet pipe or a water inlet overflow tank. The water outlet device includes a water outlet pipe or a water outlet overflow tank.

[0058] Preferably, the water inlet device is connected to the water distribution unit on one short side plate of the wetland unit module 1 of the assembled wetland device, and the water outlet device is connected to the water distribution unit on the other short side plate; forming a horizontal subsurface wetland system, The porous packing and porous structure of the wetland device are used to realize free water seepage in multiple directions, and a horizontal submerged water distribution system is formed through the water outlet pipe connected to the water distribution unit of the other short side...

Abstract

The invention provides an assembled wetland device and a wetland system, relates to the technical field of sewage treatment, and solves the technical problems of complex installation operation and high operation and maintenance difficulty of the existing wetland structure. The device comprises at least one wetland unit module, each wetland unit module comprises a supporting frame, a filler unit and a plant unit, the filler unit and the plant unit are located in the supporting frame, water distribution units are formed on four side plates and a bottom plate of the supporting frame respectively, and a water distribution assembly is formed at the top of the supporting frame. Therefore, water flow channels corresponding to multiple modes such as upward vertical subsurface flow, downward vertical subsurface flow, horizontal subsurface flow and the like are formed in the wetland unit modules. According to the invention, various wetland forms such as horizontal subsurface flow, upward vertical subsurface flow and downward vertical subsurface flow can be constructed, and the system is suitable for different application scenes. The wetland unit modules are simple in structure, the assembled wetland device composed of a plurality of wetland unit modules can be formed in a mutual splicing mode, installation is convenient, construction time is saved, and operation and maintenance are easy.

Description

technical field [0001] The invention relates to the technical field of constructed wetlands, in particular to an assembled wetland device and a wetland system with the device, which are suitable for different application scenarios such as municipal tail water, river and lake water, rural sewage, water sources and ecological landscapes. Background technique [0002] Constructed wetlands are artificially constructed and controlled grounds similar to swamps. Sewage and sludge are distributed on the artificially constructed wetlands in a controlled manner. In the process of flowing in a certain direction, sewage and sludge are mainly used. It is a technology for the treatment of sewage and sludge by the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. Constructed wetlands have gained more and more applications due to their good water effluent effect, low investment and operation and maintenance costs, and good ecological lan...
