Description

An ecological floating bed capable of planting emergent and submerged plants

technical field

The utility model relates to an ecological floating bed used for sewage treatment, in particular to an ecological floating bed which can plant emergent and submerged plants at the same time.

Background technique

Eutrophication of water body is one of the most important water pollution problems facing the world today. The ecological floating bed has the characteristics of making full use of the water surface without occupying land, adapting to a wide water depth range, high efficiency, low investment, and low operating efficiency. It can realize in-situ repair and control pollutants, and is increasingly used in eutrophication treatment and restoration of water bodies.

The existing ecological floating beds rely more on foam boards or polymer materials as carriers, artificially plant emergent plants on the surface of eutrophic water bodies, and reduce nitrogen, phosphorus and organic matter in the water body through root absorption and adsorption. So as to achieve the purpose of purifying water quality. However, due to the characteristics of high nitrogen and phosphorus content in eutrophic water bodies, relatively low chemical oxygen demand content and difficult biodegradation, it is difficult for a single aquatic plant to effectively remove pollutants in water bodies. Therefore, building an efficient aquatic plant system is the key to effectively control the eutrophication of water bodies.

Submerged plants play a great role in aquatic ecological restoration. They not only provide aquatic animals with more living habitats and shelters, but also increase dissolved oxygen in water through photosynthesis, purify water quality, and reduce the abundance of water through the microorganisms attached to them. At the same time, during the growth process of submerged plants, they absorb eutrophication components such as nitrogen and phosphorus and can promote the settlement of suspended solids in water, thereby improving the entire aquatic ecosystem. A large number of studies have shown that the synergistic purification of emergent plants and submerged plants has a good effect on removing eutrophication of water bodies.

However, often due to the fact that submerged plants cannot be planted in deeper waters or the planted submerged plants do not grow well, and the existing ecological floating beds can only plant emergent plants alone, the purification ability of water quality is limited.

Utility model content

The utility model provides an ecological floating bed capable of simultaneously planting emergent and submerged plants in order to solve the above-mentioned defects and deficiencies in the prior art.

The utility model is achieved in this way, an ecological floating bed capable of planting emergent and submerged plants, comprising an upper plastic floating plate, an emergent plant planting hole, a submerged plant planting hole, a nutrient matrix, a lower plastic floating plate and a floating bed unit Connecting hole; it is characterized in that: the ecological floating bed is in the shape of a hollow cube, including upper and lower layers of plastic floating boards, the upper layer of plastic floating boards floats on the water surface, and a planting hole for emergent plants is set in the middle, and the emergent plants are planted in the emergent water In the planting hole, the root system extends below the water surface, and a certain amount of nutrient matrix is added to the lower plastic floating plate (the amount of matrix added, while meeting the requirements that the upper floating plate will not sink), and the upper layer of the nutrient matrix (the upper floating plate) is set. The water plant planting hole is immersed in the water body to plant submerged plants. The two layers of plastic floating plates are connected together by four plastic columns with a certain height around them. Cable ties are inserted into the connecting holes of the floating bed units to connect different ecological floating bed units. Link together.

The upper plastic floating board has five hollow areas, and the middle area is used to place planting holes for emergent plants. Emergent plants planted include canna, iris, calamus, etc. Emergent plants are planted in emergent plants In the planting holes, sponges are used to fix plants to prevent emergent plants from lodging. Planting holes for submerged plants are set in four surrounding hollow areas, which is conducive to increasing the light intensity of the water body and ensuring the good growth of submerged plants.

A circular or octagonal planting hole is left in the middle for placing and planting emergent plants, and the plant root system can extend into the water body through the gap.

Four floating bed connection holes are left around the upper plastic floating plate, and different floating bed units can be spliced together with cable ties.

The lower plastic floating board is in the shape of a basket and is divided into several planting blocks. After laying the nutrient substrate, it sinks into the water body. The submerged plants planted include black algae and bitter grass.

The beneficial effect of the utility model is that: the upper and lower layers of plastic floating boards are used to plant emergent and submerged plants, and the water quality can be purified synergistically, which not only increases the hierarchical structure beauty of the ecological floating bed plant system, but also has better removal of eutrophication in the water body Effect.
