Description

technical field [0001] The invention relates to an experimental device for controlling and repairing groundwater pollution, in particular to a similar simulation experimental device for controlling groundwater pollution, and belongs to the field of experimental instruments and equipment. Background technique [0002] Osmotic reaction wall technology has great flexibility, obvious restoration effect, and high pollutant removal rate, and has been popularized and applied in groundwater pollution restoration. However, with the emergence of different types of pollution sources and the differences in groundwater pollution status, it is more difficult to determine the composition and proportion of osmotic reaction materials, as well as the location and size of osmotic reaction walls. At the same time, a large amount of manpower and material resources are required to carry out tests in actual projects, and the test period is long, so it is difficult to guarantee the stability and ef...
