Description

technical field [0001] The invention relates to a plugging simulation test device and a simulation test evaluation method, in particular to a porous medium biological blockage simulation test device and a simulation test evaluation method. Background technique [0002] Porous media is a substance composed of a skeleton composed of solid matter and a large number of densely clustered tiny voids separated by the skeleton. When the water rich in suspended solids, dissolved salts, chemical precipitation, organic matter, microorganisms and other substances passes through the porous medium, the permeability coefficient of the porous medium is easily reduced, the porosity is reduced, and the porous medium system is blocked. Porous media clogging can be divided into physical, chemical and biological clogging according to the cause. Physical clogging refers to the clogging caused by organic (biological residue) or inorganic (sand, silt and clay) particles contained in water, mainly ...
