During the subsequent waste liquid treatment, the filter screen is in a blocked state, thereby reducing the discharge efficiency of the waste liquid after treatment. In addition, the existing waste liquid treatment device only mixes the wastewater and the liquid medicine by a single-axis stirring method, thereby reducing the uniformity of the mixture of the wastewater and the liquid medicine and reducing its stirring efficiency.
