Abstract

The invention provides a system and method for observing micro-nano bubbles in a porous medium. The system comprises a model box, a laser, a camera, a lens and an image acquiring and processing module, wherein a spherical transparent resin material for simulating the porous medium is filled in the model box, the model box is provided with a water filling port for filling and containing a water body which is used for simulating underground water and is rich in micro-nano bubbles, and the surfaces of the model box are different in material and color so as to improve the imaging definition of the micro-nano bubbles in pore water of the porous medium to the maximum extent; the laser is positioned on the top of the model box and used for providing a light sheet required for observation; the camera and the lens are positioned on one side of the model box and used for observing the micro-nano bubbles in the porous medium; and the image acquiring and processing module is connected with the camera and used for acquiring and processing images. The system has the advantages of easiness, practicability, high simulation degree and high observation precision.

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 porous media. Background technique [0002] Groundwater is water retained in the pores of soil (porous media). Groundwater resources are an important part of global water resources. Under the condition of serious surface water pollution in my country, groundwater resources play an extremely important role in economic and social development. Groundwater in many areas of my country is polluted by toxic and harmful organic substances to varying degrees. The national "Twelfth Five-Year Plan" proposes to "strengthen environmental protection", solve "soil pollution and other prominent environmental problems that damage public health", and "strengthen the prevention and control of groundwater pollution". The "National Groundwater Pollution Prevention...
