Module body for wetland, preparation method thereof and artificial wetland system

Abstract

The invention provides a preparation method of a module body for a wetland, the module body and an artificial wetland system. The preparation method of the module body for the wetland comprises the following steps that filler is used for being prepared into a base block, wherein the base block is in a cuboid shape or a cube shape, the base block comprises upper and lower side faces, front and rearside faces and left and right faces which are opposite in pairs, and the upper and lower side faces of the base block are provided with first connecting teeth; water guide holes are formed in the base block. According to the artificial wetland system built from module bodies prepared through the preparation method of the module body for the wetland, the module bodies can form a multi-layer three-dimensional structure through meshing of the first connecting teeth. A hollow channel is formed in the system, the module bodies in the system can be replaced according to needs after being used for along time, and the system is small in resistance, high in oxygen dissolving property and high in treatment efficiency and can effectively solve the problem of blockage of a traditional artificial wetland.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for preparing a modular body used in wetlands, a modular body and an artificial wetland system. Background technique [0002] At present, artificial wetlands are usually constructed for sewage treatment in water-polluted areas, and such artificial wetlands generally consist of artificial substrates and aquatic plants growing on the substrates. This type of constructed wetland is widely used due to low investment and low energy consumption, but many problems have been exposed during the application process: (1) It is easily affected by climate and temperature. Once the climate and temperature change sharply, aquatic plants may die. (2) It occupies a large area, and the purification efficiency per unit area is not high, and it is not suitable for too small water body area. (3) The matrix is ​​easy to block, and the water and ventilation effects of this type of ma...

AI Technical Summary

Problems solved by technology

This type of constructed wetland is widely used due to low investment and low energy consumption, but many problems have been exposed in the application process: (1) It is easily affected by climate and temperature. Once the climate and temperature change sharply, it may lead to the death of aquatic plants

(2) The floor area is large, the purification efficiency per unit area is not high, and it is not suitable for too small water body area

(3) The matrix is ​​easy to block, and the water and ventilation effects of this type of matrix are not good enough

The above-mentioned problems limit the purification effect of constructed wetlands on sewage to a certain extent, and even limit the development of wetlands, eventually leading to the abandonment of wetlands.
