Method for constructing floating wetland

Abstract

The invention relates to a method for constructing a floating wetland. A floating carrier and plants grown in the floating carrier form a floating wetland unit, and a plurality of floating wetland units are spliced on the water surface and fixed to the water bottom through ropes and foot piles, thereby forming a floating wetland; each floating carrier is a wire mesh barrel without a cover, and floating balls are threaded on the edge of the barrel top; a cattail bag is spread on the bottom surface of each barrel, the floating plants (alligator alternanthera) are grown on the cattail bag layer, and herbaceous plant seeds are sowed in the wire mesh barrel, so that the seeds are included and mixed in the alligator alternanthera, thereby forming one floating wetland unit; and the floating wetland units are cultured in a fertile still water body, and the cultured floating wetland units can be pulled to the target water area through a waterway and spliced to form the floating wetland of required area. The invention can treat the polluted water body, and beautify the landscape of the water area.

Description

technical field [0001] The present invention relates to water pollution and eutrophication control, water plant floating bed and ecological floating island technology, and in particular to a method for constructing floating wetlands. Aquatic plants are planted in rivers, reservoirs and landscape water bodies to reduce the nutrient load of the water body, purify the water quality, improve the transparency of the water body, and beautify the water surface landscape. Background technique [0002] In recent years, the degree of eutrophication in many water bodies in my country has intensified, and water shortages often occur, which has become a bottleneck for social development. People are constantly exploring and seeking an ecological restoration solution. Among them, the measures of using floating plants as pioneer plants to build aquatic plant communities and improve the self-purification ability of water bodies are widely used in the treatment of sewage bodies. Most of the...

Problems solved by technology

Most of the floating plants used are water hyacinth, which has a single species and a simple community structure. The purification efficiency of waters in temperate regions in winter decreases significantly; and the purification sites are all selected in waters with less wind and waves and slow water flow, such as lake bays, lake beaches, and rivers. fork and pond etc

In the case of strong wind and waves and rapid water flow, in addition to direct physical damage, the friction between individual plants will aggravate the decline of floating plants; if the carrier structure of floating plants is not good, it may lead to a sharp increase in later maintenance costs

[0003] The existing technology uses foamed plastics as a carrier to provide buoyancy, but foamed plastics are easily broken and float on the water surface after being broken, causing secondary pollution

Moreover, the foam plastic board is easily overturned by waves because it is impervious to water.

Plastic materials are widely used in the carrier, and they are also made of moso bamboo. Their wind and wave resistance is also poor, and the cost of plastic products is relatively high. scale application

In addition, the plants used in the prior art are generally weak in low temperature resistance, and the plants die in winter and lose their ability to purify water bodies
