The first number threshold is set by the user, and may be set to an integer such as 1 or 2. Specifically, the user may determine the value of the first quantity threshold according to the number of types of pollutants, for example, the larger the number of types of pollutants is, the larger the value of the first quantity threshold is, but the first quantity threshold cannot exceed the number of types of pollutants.
