Ecological restoration planting strengthening area

Abstract

An ecological restoration planting strengthening area is defined by an ecological enclosure and comprises a strengthening area main body with aquatic plants planted inside, a water inlet is arranged in the upstream of the strengthening area main body, and a water outlet is arranged in the downstream of the strengthening area main body; the strengthening area main body is formed by arranging a plurality of strengthening units in an array manner, a biological filler structure is arranged on each strengthening unit, each strengthening unit comprises a horizontal column horizontal to the water surface and connecting points regularly arranged on the horizontal column at a certain distance, and connecting ropes mounted on the connecting points, and identification nodes formed by connecting biological fillers through the connecting ropes are connected with connecting rope bodies. The water flow velocity is reasonably regulated through reasonable arrangement of the strengthening units, and thestrengthening area for capture of algae and accumulative purification of nutrient elements such as nitrogen and phosphorus is created to facilitate survival and inhabitation of aquatic plants/animals, so a river ecosystem is well stabilized, the water quality improvement target is achieved, and ecological restoration of the river is promoted.

Description

technical field [0001] The invention belongs to the technical field of water body restoration and treatment, and in particular relates to an ecological restoration and planting strengthening area. Background technique [0002] With the rapid development of the national economy and the continuous improvement of the level of urbanization, my country's water pollution situation is severe, the lake ecosystem is damaged, the eutrophication of the water body is serious, and the water body transparency is not high. In my country, most lakes are used as sewage receiving bodies all the year round. The problem of water pollution is serious. A large amount of pollutants are discharged into the lake, making the pollution load exceed the self-purification capacity of the lake water. However, compared with domestic sewage and industrial wastewater containing high concentrations of pollutants, the concentration of various pollutants in the lake water is relatively low. Low, which makes the t...

Problems solved by technology

Due to the relatively closed and static characteristics of lake water, the water quality is more likely to be corrupted and smelly, and algae are more likely to grow wildly in still water bodies. Most of them use the form of creating currents in the water to turn stagnant water into living water to strengthen the self-purification effect of the water body. At the same time, fillers and aeration equipment should be laid in the flowing water body to increase the water volume of the water area, but this method has high operating costs and is difficult to apply in large-scale projects

Aiming at the problem of lake eutrophication caused by nitrogen and phosphorus, many direct purification attempts have been made in China, mostly in the form of ecological construction, relying on aquatic plants and microorganisms to absorb nitrogen and phosphorus to achieve water purification. The effect is good, but it is difficult to adapt to large-scale water treatment, and the investment cost is also an urgent problem to be solved

Moreover, in order to adapt to the convenience of human activities, especially the river channel, most of the twists and turns and biodiversity have been lost through the transformation of its banks and riverbeds. The fish in the water body have been greatly reduced due to the loss of habitat, making the water body self-purifying. The effect is weaker, which increases the difficulty of artificial water restoration

[0004] The lakeshore zone is an important part of the lake ecosystem. The ecological restoration of the lakeshore zone refers to the ecological restoration of the lake and re
