Abstract

The invention relates to a papermaking waste liquid treating device. The device comprises a rack (100), an aerating mechanism (200), a rotating mechanism (300), a lifting mechanism (400) and a filtering mechanism (500), wherein the aerating mechanism (200) comprises an aerating box (210) which is provided with an aerating chamber (212), a liquid feeding pipe (220) which is connected to the aerating box (210) and communicated with the aerating chamber (212), a liquid draining pipe (250) which is connected between the aerating box (210) and the filtering mechanism (500) and communicated with theaerating chamber (212), an aerating pipe structure which is arranged in the aerating chamber (212) and is protruded from the aerating box (210), and an air suction structure which is communicated with the aerating pipe structure; the rotating mechanism (300) is arranged on the top part of the aerating box (210) and is connected to the aerating pipe structure; the lifting mechanism (400) is arranged on the rack (100) and is connected to the rotating mechanism (300); the lifting mechanism (400) is used for driving the aerating pipe structure to move up and down. According to the scheme, the device is capable of increasing the aerating area of the aerating pipe in water, and the wastewater treating effect is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a papermaking waste liquid treatment device. Background technique [0002] my country's paper industry mostly uses grass stalks, wood pulp, etc. as papermaking raw materials. Pulping and papermaking production generally consists of pulping, pulp washing, bleaching, and papermaking processes. The pulping process of the papermaking industry includes alkaline pulping and chemical mechanical pulping. and mechanical pulping. The wastewater generated during the pulping and papermaking process is papermaking wastewater, including pulping and cooking waste liquid, washing wastewater, bleaching wastewater and paper machine white water, etc. Papermaking wastewater has complex components and poor biochemical properties, and is difficult to treat. It is one of the main sources of industrial pollution in my country. Moreover, according to different pulping methods, different raw...
