Ecological interception repairing method of black and odorous riverway

Abstract

The invention aims to provide an ecological interception repairing method. To realize the aim, the invention is characterized in that firstly a riverway is segmented to be treating function areas, three interception areas of a physical plant interception area, a physical and biological interception area, and a comprehensive system interception area are arranged successively in the river direction,wherein the physical plant interception area comprises an interception filter screen, a cobblestone permeable dike and aquatic plants, the physical and biological interception area comprises a fibersubstrate permeable dike, aquatic plants and aquatic animals, and the comprehensive system interception area comprises a fiber substrate permeable dike, aquatic plants and animals, a artificial floating island and strains.

Description

Technical field [0001] The invention relates to a black and smelly river ecological interception restoration method. Background technique [0002] Generally, in the process of river improvement, the river is intercepted in sections and the river water is pumped to a certain water level, the sludge is cleaned up, and then new water is introduced. On this basis, aquatic plants are planted along the river channel and bacteria are added. Improve the activity of sludge at the bottom of the river, and then perform aeration and oxygenation on the surface water. Such methods have a certain purification effect on the inside of the river. Therefore, it is difficult for the river water to achieve an effective purification effect, and its impact resistance is poor, and the purification effect is not Stable, if the upper reaches of the river contains garbage and floating debris, it is difficult to have obvious treatment effects. Summary of the invention [0003] In view of the above problems,...

Problems solved by technology

[0002] In the general river channel treatment process, the river channel is intercepted in sections, the river water is pumped to a certain water level, the sludge in it is cleaned, and then new water is brought in. On this basis, aquatic plants are planted along the river channel, and bacteria are put in. Improve the activity of river bottom sludge, and then aerate and oxygenate the surface water, etc. These methods have a certain purification effect on the interior of the river, so it is difficult to achieve effective purification of the river water, and the impact resistance is poor, and the purification effect is not good. Stable, if the upper reaches of the river contain garbage and floating objects, it is difficult to have a significant treatment effect
