Abstract

The invention provides a system and a method for observing micro-nano air bubbles in water body. The system comprises a model box, a laser device, a camera, a lens and a picture acquiring and processing module, wherein the model box is provided with a water filling nozzle, and can be filled with and contain the water body which is rich in micro-nano air bubbles, moreover, each face of the model box adopts different materials and colors, and the imaging definition of the micro-nano air bubbles in the water body is improved to the greatest extent; the laser device is located at the top of the model box, and is used for providing a light source needed for observation; the camera and the lens are arranged on one side of the model box, and are used for observing the micro-nano air bubbles in the water body; and the picture acquiring and processing module is connected with the camera, and is used for acquiring and processing pictures. The system and the method provided by the invention are simple, convenient, practical and high in observation accuracy.

Description

technical field [0001] The invention belongs to the fields of water conservancy and hydropower engineering and environmental protection engineering, and in particular relates to a system and method for observing micro-nano bubbles in a water body. Background technique [0002] Water resources are the key resources for human production and life. At present, environmental water bodies are seriously polluted. Water resource protection and water pollution control have become the most concerned issues in modern society. The aeration method is an important method to deal with water pollution. Its principle is to exchange gaseous substances and remove volatile substances in water through full contact between water and air, or to make gas escape from water, to remove water odor or carbon dioxide and hydrogen sulfide, etc. Harmful gases; or dissolve oxygen into water to increase the concentration of dissolved oxygen to achieve the purpose of removing iron and manganese or promoting t...
