Problems solved by technology

[0003] In recent years, various water purification technologies have been developed around the world. Usually, sewage is transported to sewage treatment plants for centralized treatment. Treating rivers in this way can usually achieve certain results, but it requires sewage interception, pipe laying, and construction of various facilities. , has the disadvantages of large investment and high cost, and it is difficult to spread and use it in a large area except for some seriously polluted rivers
In addition, the pollution of artificial lakes in cities is becoming more and more serious, which seriously affects the landscape effect of ecological waters. Therefore, the treatment of polluted water bodies is a major pro

Abstract

The invention mainly discloses a solar water purifier for lakes and a water purification method thereof. According to the technical scheme, the solar water purifier comprises a main body, a purification system, an energy system, a drive unit, a lighting device and a fixation device. The energy system comprises a solar cell panel, a storage battery and a charging panel. An oxygenation chamber, a disinfection chamber and a purifying chamber are arranged inside the main body. An ozone generator, an air compressor, a bubble generator and an aerator pipe are disposed inside the oxygenation chamber. A drug blending tank is arranged inside the disinfection chamber. A purifier is disposed inside the purifying chamber. When the device operates, installation and pilot run of the device are firstly carried out. After successful pilot run, the device is put into a lake. By mobile positioning of the drive unit, a water body undergoes disinfection, oxygenation and purification. The energy system provides energy. Thus, energy is self-sufficient. The solar water purifier has a simple structure, is low-cost and clean. By various purification methods, purification efficiency is high. By the floating and stationary combined design, position of the device can be controlled freely. Thus, repair rate of water body is high. The solar water purifier is easy to operate.

Description

technical field [0001] The invention relates to a solar water body purification device applied to lakes and a method thereof. Background technique [0002] In order to promote plant growth and increase the yield of agricultural products, people often apply more nitrogen and phosphorus fertilizers, which are easily lost during rainfall or irrigation. The loss methods of nitrogen and phosphorus nutrients are as follows: (1) enter the surface water body with the surface runoff; (2) infiltrate to form a subsurface flow (soil midflow), move laterally through the soil, and then discharge into the surface water body; (3) Seeps down through the soil layer into groundwater. Excessive nitrogen and phosphorus fertilizers enter rivers and lakes, which can easily cause eutrophication of water bodies. Eutrophication reduces the transparency of water, making it difficult for sunlight to penetrate the water layer, thereby affecting the photosynthesis of plants in the water and the release...
