Water Ecological Comprehensive Restoration System

Abstract

The invention discloses a comprehensive restoration system for water ecology, including an oxygen-enhancing aeration system and an animal and plant ecological breeding system, which are alternately arranged along a river channel; the oxygen-enhancing aeration system includes an aeration pan, an air supply main pipe, an air supply The branch pipe and the air supply distribution plate; the air supply main pipe is arranged perpendicular to the river channel, and the intake end of the air supply branch pipe is vertically bent downward and then connected to the air supply main pipe. The air distribution plate is composed of the main channel and several distribution pipes. The distribution pipes are distributed on the circumferential side wall of the main channel in a divergent shape. An aeration plate is connected; the plant ecological aquaculture system includes plant floating islands, fish nests and ecological fish reefs arranged in sequence from top to bottom. The cross section enclosed by the back inclined plate is an isosceles trapezoid hollow hexahedron. The oxygenation effect is good and the repair effect is remarkable.

Description

technical field [0001] The invention relates to a water ecology comprehensive restoration system used for river courses, and belongs to the technical field of ecology and environmental protection. Background technique [0002] With the continuous improvement of industry and people's living standards, water pollution has seriously threatened the health of the ecological environment and human life. In order to improve the level of water pollution control, major scientific research institutes and scientific research institutions have invested a lot of energy. At present, there are many ways to control and restore the water environment of rivers, including oxygen-increasing aeration systems, floating islands, fish reefs, and fish nests. [0003] For aerobic aeration systems, there are generally problems such as intricate pipeline laying, difficult maintenance and detection, time-consuming installation and disassembly, which are not conducive to widespread promotion. In the sys...

AI Technical Summary

Problems solved by technology

Most of the aeration pans are composed of aeration pan brackets and aeration tubes. The aeration tubes are fixed on the aeration pan brackets by ropes. It is very troublesome to install, disassemble and replace the aeration tubes. If they are tied too loosely, the aeration tubes will The position is not fixed, and if it is tied too tightly, the aeration tube will be squeezed and deformed; the aeration micropores on the aeration tube are distributed in a straight line, usually the aeration micropores face upward, and the aeration direction is single, so the aeration effect is not ideal , Impurities can easily cause blockage after entering the aeration tube; the structure of the aeration disc bracket is complex and the manufacturing cost is high

[0004] In addition, due to the unreasonable layout of the oxygen-increasing aeration system, floating islands, fish reefs, and fish nests, especially the structural design of the fish reefs, the effect of comprehensive restoration of water ecology is seriously affected
