Enhanced aeration ecological restoration device

Abstract

The invention discloses an enhanced aeration ecological restoration device. The device consists of: a floating box, solar cell panels, a first water pipe and a second water pipe, a water pump, activated carbon filler and biological filler, an anode electrode and a cathode electrode. Nano oxygen bubbles produced by anode electrode electrolysis are fully utilized for aeration and oxygenation of water, the nano oxygen bubble dissolved water passes through the activated carbon filler and the biological filler disposed in the first water pipe and the second water pipe respectively to strengthen aerobic microbial growth and pollutant degradation, and returns to the river bottom. Hydrogen produced by cathode electrode electrolysis is utilized to promote the growth of anaerobic microorganisms in the river sediment part and digest organic matters, also a bending part is utilized to drive the whole device to move in river, thus realizing ecological restoration of the whole river. The device provided by the invention utilizes green solar energy to enhance water oxygenation by aeration, realizes ecological restoration of river water, and has the advantages of simple structure, low price, mobility, convenient use, low maintenance cost and no energy consumption.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment in environmental protection, and in particular relates to an enhanced aeration ecological restoration device. Background technique [0002] Aeration and re-oxygenation is a measure to restore the ecological function of the water body environment by artificially controlling the method of oxygenating the water body. Since the 1960s, artificial aeration enhancement technology has been applied to river management. Operations at home and abroad have shown that artificial aeration and reoxygenation in polluted rivers can change the black and odorous state of the polluted water body, and cause the reducing substances in the upper sediment of the river to be oxidized and degraded. Aeration can form an ecological environment dominated by aerobic bacteria in the river channel, thereby reducing organic pollutants in the water body in a short period of time, increasing DO in the water body, enhancin...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional aeration methods use blower aeration, which has a simple structure and is easy to install. However, the aeration performance is poor. The aeration equipment is generally installed at the bottom of the water, and a large amount of sludge and particles are deposited at the bottom of the sewage, which is not only easy to Blocking the aeration port also makes the gas not evenly contact with the sludge and sewage, which reduces the treatment effect; moreover, the energy consumption of the aeration equipment is high, and the power consumption of aeration and oxygenation generally accounts for 50% of the total energy consumption of the sewage treatment plant. % or more, resulting in high operating and maintenance costs during long-term operation of the system, which is also the reason why many established sewage treatment plants are difficult to maintain normal operation
