Water ecology comprehensive repairing system

Abstract

The invention discloses a water ecology comprehensive repairing system which comprises oxygenating and aerating systems and animal and plant ecological cultivation systems which are arranged alternately along the riverway at intervals, wherein each of the oxygenating and aerating systems comprises an aerating disc, an air supply general pipe, an air supply branch pipe and air supply dividing discs; the air supply general pipe is arranged vertical to the riverway, the air inlet end of the air supply branch pipe is vertically bended downward and is then communicated with the air supply general pipe, the air supply dividing discs are arranged along the extension direction of the air supply branch pipe at intervals, and each of the air supply dividing discs is composed of a main channel and a plurality of dividing pipes; the dividing pipes are radially distributed on the circumferential side wall of the main channel, each of the dividing pipes is provided with an automatic control valve and is connected with one aerating disc through an air supply hose; each of the animal and plant ecological cultivation systems comprises a plant floating island, a fish nest and an ecological fish shelter which are sequentially arranged from bottom to top; the ecological fish shelter is a hollow hexahedron which is encircled by a top plate, a bottom plate, a left vertical plate, a right vertical plate, a front oblique plate and a rear oblique plate, wherein the cross section is an isosceles trapezoid. The system is good in oxygenating effect and remarkable in repairing effect.

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
