Embodiment 1

[0021] 1. Extract the silt at the bottom of the river channel for component analysis and investigation: select multiple sections of water on the river channel, extract the silt at the bottom respectively, conduct component analysis, and determine the pollutants.

[0022] 2. Corresponding to the pollutants in each section, select the aquatic plants that can purify and absorb the above pollutants, and evenly bind the aquatic plants to the support cross frame 2 of the planting frame, so that the roots are downward, so that they can easily penetrate into the river bottom silt.

[0023] 3. Assemble multiple sets of planting frames bound with aquatic plants, insert them into the river bottom, and then fix the vertical fixing frame 1 on both sides of the river bank to ensure that the fixing piles 3 on the supporting horizontal frame 2 can be inserted into the silt for fixing. Bottom weight 21 reinforces the planter.

Abstract

The invention relates to the technical field of riverway water body treatment, in particular to an ecological restoration method for a water landscape riverway polluted water body, which comprises the following steps: S1, extracting sludge at the bottom of a riverway for component analysis investigation; s2, aquatic plants for purification are selected, a plant planting frame is built, and the aquatic plants are bound to the planting frame; s3, inserting the planting frame bound with the aquatic plants into the river bottom; and S4, regularly sampling and analyzing the river bottom sludge, and replacing the aquatic plants. The bottom sludge can be purified and restored according to the pollution condition of a river channel, so that the water quality of a water body is changed, and the purpose of ecological restoration is achieved.

Description

technical field [0001] The invention relates to the technical field of river water body treatment, in particular to an ecological restoration method for water landscape river polluted water bodies. Background technique [0002] Urban rivers are an important part of the entire urban ecosystem. However, due to the large number of residents along urban rivers, human production and life have had a great impact on urban rivers, resulting in the continuous degradation of urban river ecological functions, and even Loss of self-purification. In recent years, the living standards of human beings have been greatly improved, and at the same time, human beings have gradually established the concept of ecological landscape rivers. Human beings have increased the efforts to restore and control urban landscape rivers, and have contributed to maintaining the ecological balance of the city and improving the appearance of urban landscapes. It is of great significance to protect the living en...
