A modular body for wetlands, its preparation method and constructed wetland system

Abstract

The invention provides a method for preparing a modular body used in wetlands, a modular body and an artificial wetland system. The method for preparing a modular body used in wetlands includes the following steps: using fillers to prepare a base block, and the base block is in the shape of a cuboid Or a cube, the base block includes three sets of opposite sides: upper and lower, front and rear, left and right; the step of forming first connecting teeth on the upper and lower sides of the base block; the step of forming water guide holes on the base block. In the constructed wetland system constructed by the modular bodies prepared by the method for preparing modular bodies used in wetlands, a plurality of modular bodies can form a multi-layer three-dimensional structure through the engagement of the first connecting teeth, and a hollow channel is formed in the system, and the system The modules in the system can be replaced as needed after long-term use. The system has low resistance, high oxygen solubility, and high treatment efficiency, which can effectively solve the problem of fouling in traditional constructed wetlands.

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.
