Description

Technical Field

[0001] The present invention relates to the technical field of wetland ecological restoration, and particularly relates to a floating wetland multi-functional combined module for slow-flowing water bodies. Background Art

[0002] The ecological restoration of slow-flowing water bodies is of great significance for improving the water environment quality. As an effective ecological restoration means, floating wetlands have been widely used.

[0003] However, there are some problems in the actual use of existing floating wetland modules. For example, after plants grow for a period of time, the roots of some plants are too long and easily occupy the living space of other neighboring plants, resulting in the decay of the roots of the occupied plants. It is necessary to regularly prune the roots of the plants. However, after the existing floating wetlands are assembled, it is difficult to know the growth state of the plant roots and impossible to prune the roots of the plants. Moreover, when the area of the floating wetland module is large, it is difficult to prune the plants in the center of the module. Workers need to stand on the module, but many modules cannot bear the weight of workers, making the pruning operation of the plants extremely inconvenient.

[0004] In addition, the environment inside the module is not conducive to the respiration and growth of plant roots, easily causing the decay of plant roots, affecting the survival of plants and the purification effect of the wetland, and reducing the stability and durability of the entire floating wetland system. Summary of the Invention

[0005] In view of the above deficiencies of the prior art, the present invention provides a floating wetland multi-functional combined module for slow-flowing water bodies, which is convenient for pruning the roots and surface of plants.

[0006] To achieve the above invention purpose, the technical solution adopted by the present invention is as follows:

Through the setting of the clamping plate, on the one hand, the root system of the plant is trimmed by the sharp edge of the clamping plate to keep the root system of the plant at a certain length; on the other hand, the opening of the outer basket loaded with the planting substrate module unit is periodically opened and closed, so that the denitrification promoter and the phosphorus removal promoter maintain a high concentration in the outer basket, avoiding the direct dilution of the promoter by the stagnant water body. Combined with beneficial bacteria such as nitrifying bacteria, denitrifying bacteria, and sulfate-reducing bacteria produced by the plants planted in the planting substrate, the stagnant water body is purified.
