When the enzyme preparation is added, the motor of the stirring component can be started simultaneously, so that the stirring paddle is driven to rotate, and the waste liquid and the enzyme preparation are mixed more uniformly. After enzymolysis is finished, the heating device can be started to heat the enzymolysis waste liquid, so that the enzyme in the waste liquid is inactivated, and simultaneously, the protein in the waste liquid is promoted to denature to form precipitate. After heating and cooling, a flocculating agent can be added for flocculation (and the flocculating agent can also be added when the process allows), and the stirring component can be started for stirring when the flocculating agent is added.
