Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a papermaking sewage recovery and treatment device. Background Art

[0002] The papermaking industry uses wood, straw, reed, rags, etc. as raw materials, and separates cellulose through high-temperature and high-pressure cooking to make pulp. In the production process, the non-cellulose part in the raw materials is finally discharged as papermaking black liquor. The black liquor contains lignin, cellulose, volatile organic acids, etc., has a bad smell, and has strong pollution. When treating papermaking sewage, since a large amount of paper fibers are contained in the sewage, in order to avoid waste caused by the direct discharge of paper fibers following the sewage, it is necessary to filter and recover the paper fibers in the sewage.

[0003] However, there are some problems in the prior art: the existing papermaking sewage recovery and treatment device usually adds a flocculant to the sewage and then uses a filter plate to separate the solid and liquid of the papermaking sewage to achieve the purpose of filtering and recovering the paper fibers in the sewage. However, after adding the flocculant, it is necessary to stand for a period of time for the flocculant to complete mixing and coagulate the paper fibers in the sewage, and the coagulation efficiency is low. Moreover, when the existing equipment is filtering, the paper fibers cannot be recovered in time, and it is necessary to filter all the sewage before collecting. The paper fibers piled on the filter plate are easy to cause blockage of the filter plate. Therefore, we propose a papermaking sewage recovery and treatment device. Summary of the Utility Model
