Submerged type bubble-free high-efficiency oxygenated water body restoration system

Abstract

The invention relates to a submerged type bubble-free high-efficiency oxygenated water body restoration system, comprising an oxygen supply system and a dissolved oxygen system; the oxygen supply system is used to inject oxygen in the water of the dissolved oxygen system and the dissolved oxygen system is used to release high-concentration oxygen in water body for dissolving oxygen in water. The oxygen supply system comprises an air compressor, an oxygen generator and dissolved oxygen tanks which are connected in sequence by pipelines and convey high-concentration oxygen to dissolved oxygen tanks of the dissolved oxygen system, and the high-concentration oxygen is generated by the oxygen generator and has purity of higher than 90%; the dissolved oxygen system also comprises a submerged pump which conveys water to the dissolved oxygen tanks, the oxygen tanks carries out bubble-free mutual dissolving with the oxygen so as to obtain high-concentration oxygenated water, and the high-concentration oxygen dissolved water is released into the water body through the dissolved oxygen tanks so as to realize bubble-free oxygenation. The system also can be provided with a control system so as to control self starting oxygenation, or is further provided with a monitoring system which adjusts and controls the starting and stopping and the flow rate of oxygenation in real time according to various indexes. The submerged type bubble-free high-efficiency oxygenated water restoration system has characteristics of low power consumption, high efficiency and the like, can effectively reduce the content of nitrogen and phosphorus in water sources and water bodies and can further restrict burst of water bloom.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to an aeration device in the industry of repairing polluted water bodies. Background technique [0002] With the rapid development of industry and agriculture in my country and the acceleration of urbanization, the discharge of pollutants in industrial wastewater, domestic sewage, and agricultural irrigation wastewater is increasing. After the nitrogen and phosphorus nutrients enter relatively closed waters, they will be exposed to sunlight , can easily lead to eutrophication of water bodies and cause damage to the utilization of water resources. Cyanobacteria blooms mostly occur from late spring to summer from May to August, with obvious seasonality. Temperature, light, nutrition, etc. are all factors affecting its growth. When the water temperature is above 20°C, the water body is eutrophic, the pH value is high, and the light is suitable, blue-green algae will multiply and form a blo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a submerged water-free bubble-free high-efficiency oxygenation solution for the problems of single aeration and reoxygenation function of existing artificial aeration equipment, high energy consumption, large power loss, and difficulty in restoring the self-purification function of polluted water bodies. The water body restoration system is suitable for the restoration of polluted water sources in small towns. It has the characteristics of low energy consumption and high efficiency, and can effectively reduce the nitrogen and phosphorus content in water sources and gradually restore the water body ecosystem.
