Description

Emergent aquatic plant decontaminating planting and fixing device

Technical Field

The utility model relates to a plant planting device refers in particular to a device that has a river coastal emergent aquatic plant field planting and pollution purification is taken to pearl river delta belongs to waters environment improvement and view greening technical field.

Background

The Zhujiang Delta is located in the central and south parts of Guangdong province, has developed water system and communicated river network, is the most economically developed area of the Guangdong province, and is one of the most active industrial production areas in China. The economy is rapidly developed, and simultaneously, a large amount of sewage is discharged into rivers, lakes and seas, so that the problems of serious water body pollution, eutrophication and water quality water shortage are prominent. Before entering the Zhujiang delta, the water quality of the Zhujiang water system is excellent, and the water eutrophication phenomenon is serious after the Zhujiang delta water system flows through the Zhujiang delta. According to 2017, environmental condition bulletin of Guangdong province shows that: of 10 heavily polluted offshore shore functional areas in the whole province, 8 are located in the sea area of the Zhujiang estuary. The water quality problem, the water resource shortage caused by water pollution and the water ecology problem seriously affect the economic and social development of the Zhujiang Delta area and the life and health of residents of the Zhujiang Delta, so that the research on the water body restoration has important significance on the sustainable development of the Zhujiang Delta.

At present, the method for restoring the eutrophic water body mainly comprises a physical method, a chemical method and a biological method. The more commonly used physical methods comprise sediment dredging, sediment covering and water diversion projects, the operation cost is higher, and some insurmountable defects exist, such as the re-release of nutrient salts in sediments and the damage to the original benthic ecosystem in the sediment dredging process; the chemical dosage used by the chemical method is difficult to master, and secondary pollution is easy to generate; the biological method mainly utilizes animals, plants and microorganisms to adsorb, degrade and convert pollutants to realize water body purification and aquatic ecosystem restoration, and is the most attention-focused water body restoration method at present. The technology for restoring water body pollution by utilizing plants in the 70 th century till now is valued by the research of the environmental field due to the advantages of low cost, low energy consumption, small environmental pollution and the like.

Although the traditional stone masonry or concrete riverway has a stable structure and has the functions of preventing water flow and waves from eroding and brushing the bank slope foundation soil, the water body is sealed in the riverway, the material relation between ecological elements between the water body and the near-bank land soil is cut off, aquatic plants and aquatic animals cannot grow normally and disappear, and the biological diversity is reduced rapidly, so that the ecological environment of the whole river is influenced. The aquatic plants can purify and restore polluted water bodies, can fix soil and protect banks, beautify water body landscapes, and grow emergent aquatic plants on the coasts of rivers. As the roots and the roots of emergent aquatic plants grow in the bottom mud of water and the stems and the leaves protrude out of the water surface, during the construction and the planting construction, as the root systems of newly planted plants are not consolidated with the matrix soil into a whole, the loose matrix foreign soil is easy to be washed away along with the water level change of a water body, the flow of river water or the impact of heavy rain, is difficult to be fixed or survive and cannot play the roles of purifying water and fixing slopes and protecting banks.

The invention of planting emergent aquatic plants along the bank of a river has certain limitations in the application range, for example, CN105923776A discloses a method for constructing a waterfront plant zone for filtering non-point source pollution, CN 105256766A discloses a quasi-ecological water bank protection slope structure, CN202054670U discloses a structure of an emergent aquatic plant planting bed, the invention is suitable for natural riverways with a relatively slow slope bank, and CN104594288A is a novel Taihu lake bank planting ecological restoration process suitable for large lakes. CN206791274U an emergent aquatic plant planting device for hardening embankment is suitable for solidifying embankment in city river. Some patents are not environment-friendly because most of the materials are hard steel, polyethylene plastic and the like, and the cost is high.
