[0002] White liquor is mostly made of starch-containing materials, such as sorghum, corn, barley, wheat, rice, and peas, etc. Its brewing process is generally divided into two steps: first, Aspergillus oryzae, Aspergillus niger and Aspergillus flavus are used to decompose starch into sugar, which is called saccharification process; the second step is to ferment glucose into alcohol by yeast. The production process of white liquor requires a large amount of water. In the production process of white liquor, the washing water, the washing bottle water, the distillation cooling water and the cooking water are discharged as wastewater, which not only pollutes the environment, but also greatly wastes water resources.

[0030] The pretreatment mechanism 4 drives the filter screen frame 43 to lift through the electric push rod 41, after the filter screen frame 43 intercepts large-particle impurities (such as lees residues), the filter screen frame 43 is lifted to the top of the treatment tank 3 for cleaning or replacement, the two groups of electric push rods 41 are synchronously arranged, the electric push rod 41 realizes manual operation-free, reduces downtime, improves efficiency, and the symmetrical driving ensures that the filter screen frame 43 lifts stably and avoids jamming or leakage caused by uneven force on one side.

[0031] The bottom of the treatment tank 3 is fixedly connected with a three-way pipe 5, and the two bottoms of the three-way pipe 5 are respectively connected with the interiors of the two groups of filter tanks 2.
