Abstract

The invention relates to the technical field of test equipment, in particular to a test device for simulating pollutant migration and transformation in icing and melting processes of a water body. The device comprises: a transparent cylinder body with the top open and the bottom closed, used for holding a test water body; a transparent box body, wherein the top of the box body is provided with a through hole through which the cylinder body is provided in the box body; a first refrigerating system including a first evaporator provided in the cylinder body close to an opening of the cylinder body, wherein the first refrigerating system is used for controlling the temperature of a first space from a surface of a test water body in the cylinder body to the opening of the cylinder body through the first evaporator; and a second refrigerating system used for controlling the temperature in the box body. According to the test device provided by the embodiment of the invention, the icing and melting processes of a test water body can be simulated, so that researchers do not need to extract a water sample on site, but can easily know the influence of the icing and melting processes on the migration and transformation of pollutants.
