Problems solved by technology

[0003] In order to overcome the shortcomings of existing constructed wetlands, the present invention provides a detachable constructed wetland, which is composed of several relatively independent and movable wetland modules and filling units, which can be connected and combined arbitrarily according to the processing needs, which can shorten the construction time of wetlands , the wetland module and filling unit can be produced industrially, and the project quality is guaranteed; the constructed wetland can be disassembled and transferred as a whole, and reused in another place, without permanently occupying the land, and has low requirements on the shape of the land; after the wetland is completed, it is easy to maintain, and can be removed when blockage occurs. The packing unit can be taken out separately, and can be put back after simple cleaning. There is no need to take out the wetland module for maintenance, and it will not affect the normal use of the artificial wetland.

Embodiment 1

[0027] The artificial wetland described in the figure is composed of four independent modular units (12) combined in series and parallel connection. The modular units (12) are set up and made of iron plate materials to form a modular box (3). (3) A water inlet pipe (1) is arranged at the front, a water baffle (4) is arranged between the filling units (13), and a water outlet pipe (2) is arranged at the rear of the module box (3). Each module unit (12) is provided with four packing units (13), the packing unit frame (5) of the packing unit (13) is made of metal, and the packing unit frame (5) is equipped with a lifting ring (11), and the packing unit Metal grids (6) are arranged around and at the bottom of the unit frame (5); the filler unit (13) is filled with foam ceramics (7), filter sponges (8), light porous ceramsites (9) and sand from bottom to top. (10) Planting wetland plants on sandy soil.

Embodiment 2

[0029] The constructed wetland is composed of three independent modular units (12) combined in series. The modular unit (12) is made of cement modules to form a modular box (3), and a water inlet pipe is set in the front of the modular box (3) (1) A water baffle (4) is arranged between the packing units (13), and a water outlet pipe (2) is installed at the rear of the module box (3). Each module unit (12) is equipped with two packing units (13), the packing unit frame (5) of the packing unit (13) is made of metal, and the packing unit frame (5) is equipped with a lifting ring (11), and the packing unit Plastic grids (6) are arranged around and at the bottom of the unit frame (5); the packing unit (13) is filled with foam ceramics (7), filter sponges (8), light porous ceramsites (9) and sand from bottom to top. (10) Planting wetland plants on sandy soil.

Embodiment 3

[0031] This constructed wetland is composed of six independent modular units (12) combined in parallel. The modular units (12) are set up to be made of plastic and steel as a framework to form a modular box (3), in the front of the module box (3) A water inlet pipe (1) is arranged, a water baffle (4) is arranged between the filling units (13), and a water outlet pipe (2) is installed at the rear of the module box body (3). Each module unit (12) is equipped with two packing units (13), the packing unit frame (5) of the packing unit (13) is made of metal, and the packing unit frame (5) is equipped with a lifting ring (11), and the packing unit Plastic grids (6) are arranged around and at the bottom of the unit frame (5); the packing unit (13) is filled with foam ceramics (7), filter sponges (8), light porous ceramsites (9) and sand from bottom to top. (10) Planting wetland plants on sandy soil.

Abstract

The invention discloses a modularized detachable constructed wetland, which is formed by a plurality of wetland modules, each module is relatively independent, and the module comprises a plurality of detachable filler units; each filler unit consists of a filler frame, a net separator and a filler layer, and the filler layer comprises a soil layer, a soil separation layer and a porous light filler layer from top to bottom. According to the water quality, the water yield and the water outlet requirement of the treated sewage, the wetland modules can be connected in series and in parallel or compositely connected to constitute a constructed wetland system. The modularized detachable constructed wetland has a simple structure, is convenient to install, is low in cost, and adapts to industrialized batch production. In the operation process of the wetland, the wetland modules and the filler units can be replaced and repaired at any time, the system is not blocked easily, the treatment effect is good, and the land can be reused.

Description

Technical field [0001] The invention relates to a device for treating domestic organic sewage, which is suitable for places where land cannot be permanently occupied and the transformation of traditional artificial wetland sewage treatment projects, and is especially suitable for the treatment of decentralized domestic organic wastewater. Background technique [0002] Artificial Wetland (Artificial Wetland) is a new type of wastewater biological treatment technology developed in the late 1970s. It uses the triple synergy of physics, chemistry and biology in the natural ecosystem to achieve the purification of wastewater. Its features such as low construction cost, low energy consumption, good treatment effect, low operating cost, easy management, and beautification of the environment have made it widely used in the treatment of urban and rural domestic sewage in various countries around the world. However, due to the large area of ​​the constructed wetland, more fillers are requi...
