In order to avoid risks of leakage, fire, explosion, corrosion, etc. that may occur during these reactions, it is necessary to test the compatibility of the two wastes before they are mixed. The existing testing method mainly comprises the steps of pouring two or more wastes to be mixed into a conical flask or a similar open glass container according to a certain proportion, stirring by adopting a magnetic stirring device to mix the wastes, and monitoring the temperature change in the mixing process and observing whether the waste mixture is thickened or not and whether bubbles are generated or not in the mixing process. The problems with the current testing process are: the heat exchange efficiency between the test process and the environment is overhigh; the stirring rate cannot be accurately controlled, and even in special cases, the stirring can be stalled; the temperature change cannot be monitored in real time during the test process.
