Problems solved by technology

In addition, some lakes and rivers are difficult to settle due to the extremely small suspended sediment in the water, resulting in turbid water quality all year round and extremely low water transpa

Embodiment 1

[0027] like figure 1 As shown, in this example, the research area is located in the water source of Jinshu Bay (31.3826°N, 120.416°E) in Jinshu Village, Gonghu Lake, Suzhou, Jiangsu Province, which provides water sources for Suzhou Baiyangwan Water Plant and Xiangcheng Water Plant, which is typical Subtropical monsoon climate with abundant rainfall. Jinshu Port Riverside (A) has a total length of 300m and a width of 7-9m. They are all connected to Jinshu Bay, the main river channel. There are only a few types of aquatic plants in Hanoi. Most of the land on both sides of the riverside is agricultural land and rural residential areas, which are non-point source polluted areas. 20800m 2 , the main source of pollution is forest land fertilization, of which the area of ​​forest land is 14000m 2 . The water quality of the river course is Class V-Inferior Class V, the thickness of the sediment to be repaired is 40-65cm, and the total organic matter (OM) content is 6.25mg / L.

Embodiment 2

[0035] Jinshu Port Duantoubang (B) river course ( figure 1 ) is 185m long, the channel width is 11-14m, the water depth is 1.7-1.8m, and the transparency is 0.8m. The eutrophication of the river is very serious, the water quality is Ⅳ-Ⅴ, and the pollution source mainly comes from the domestic sewage of residents. The surface of the river is completely covered by duckweed, the photosynthesis of submerged plants is severely restricted, the silt is black, and the water quality has begun to stink. The thickness of the sediment to be repaired is 40-65cm, and the total organic matter (OM) content is 5.75mg / L.

[0036] An emergent plant area 100, a mixed area of ​​emergent plants and submerged plants 110, and a submerged plant area 120 are sequentially constructed in the water-land transition zone between the embankment and the water body, and the above three areas are set up for the growth of plants and snails. The groove 130; the width ratio of the emergent plant area 100, the mi...

Abstract

The invention discloses a method for building an ecological slope protection by reasonably mixing and matching spiral shells with water plants. The method includes the steps: sequentially building an emergent plant area, an emergent plant and submerged plant mixing area and a submerged plant area on a water and land staggered zone between a bank and a water body, and setting grooves for growth of the plants and the spiral shells on the three areas; planting emergent plants in grooves in the emergent plant area, planting emergent plants and submerged plants in grooves in the emergent plant and submerged plant mixing area at intervals, and planting the submerged plants in grooves in the submerged plant area; throwing the spiral shells into the grooves in the three areas. By the method, the content of nitrogen and phosphorous in the water body can be effectively reduced, organic substrates in mud and sand are changed into inorganic salt, the shading effect of attaching organisms for the submerged plants is decreased, deciduous old leaves of the plants are decomposed, excessive release of nutritive salt after the old leaves are decayed is avoided, the content of phytoplankton in water can be reduced by the spiral shells, and excrements of the spiral shells can facilitate growth of the water plants.

Description

technical field [0001] The invention belongs to the technical field of water body environment, and in particular relates to a method for rationally mixing snail shells and aquatic plants to construct ecological slope protection. Background technique [0002] In recent years, with the rapid improvement of social economy, phenomena such as black and odorous rivers, eutrophication of lake water, and red tides in coastal waters have continuously entered people's field of vision. Water pollution not only seriously affects people's life and production, but also beautifies the visual landscape, and the desertification of the ecotone makes banks more vulnerable to water erosion. With the development of society and economy, people begin to beautify and protect the ecological environment and gradually improve their awareness. In this context, water ecological restoration has quietly emerged. The ultimate goal of water ecological restoration is to build a benign ecosystem. Such as: ...
