Solar energy day and night different gas aeration and algal control device for shallow lakes

Abstract

The invention discloses a solar energy day and night different gas aeration and algal control device for shallow lakes. The device includes a suspended grid structure, a CO2 aeration system, an air aeration system, a solar power generation system and a controller. The CO2 aeration system and the air aeration system are arranged on the lower part of the suspended grid structure. The solar power generation system and the controller are arranged on the upper part of the suspended grid structure. The controller and the solar power generation system are connected to the air aeration system. The device of the invention realizes algal control in multiple ways to improve the water quality, supply power by using solar generation, which is efficient, energy saving, environmentally friendly and costsaving, is convenient in moving, can change an algal control area according to needs, which is strong in flexibility, is simple in device structure, small in size and convenient in operation and maintenance, and is especially suitable for controlling algae in the shallow lakes to improve the water quality.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a solar energy diurnal and night heterogeneous gas aeration control algae control device for shallow water lakes. Background technique [0002] With the expansion of the scale of cities in our country, the improvement of living standards and the rapid development of social economy, cities have higher and higher requirements for water quality, greater demand for water volume, and gradually increased requirements for ecological environment. However, in recent years, with the rapid development of industrial and agricultural scale, the discharge of pollutants is far more than before, and most of the lakes and reservoirs that used to be water sources in my country have serious eutrophication. At present, most of the main inland lakes in my country, such as Taihu Lake, Chaohu Lake, Dianchi Lake, Donghu Lake, etc., with an average depth of only about 1.8-3.0m, have been ...

Problems solved by technology

However, this method is suitable for deep-water lakes and reservoirs, and there are generally technical problems such as excessive energy consumption and frequent maintenance of equipment during use, which greatly increases the cost of algae control and is difficult to promote on a large scale

[0019] 4. The method of draining water from the bottom of the reservoir can effectively remove nutrients from the bottom layer, cut off the source of algae nutrition, and achieve the purpose of inhibiting algae. However, this method has a large loss of storage capacity for lakes and reservoirs with small water storage, and the operation of draining water from the bottom of the reservoir is difficult. , higher risk
