Abstract

The invention discloses a papermaking sewage treatment method, and belongs to sewage treatment devices. Equipment adopted by the method comprises a sewage treatment tank, a preliminary filtering device, a debris removing device, a fishing filtering device, an air jetting device and a sewage discharging device, wherein the preliminary filtering device is installed at the top of the sewage treatmenttank, the debris removing device and the fishing filtering device are vertically arranged beside the sewage treatment tank, the debris removing device is located beside the preliminary filtering device, the outer wall of the sewage treatment tank is provided with a sealing assembly matched with the debris removing device, the air jetting device is installed at the bottom end in the sewage treatment tank, and the sewage discharging device is installed at one end, far away from the debris removing device, of the sewage treatment tank. The papermaking sewage treatment method is simple in structure, improves the treatment efficiency of sewage, saves production cost and is suitable for treatment of papermaking sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a papermaking sewage treatment method. Background technique [0002] The paper industry uses wood, straw, reeds, rags, etc. as raw materials, and cellulose is separated by high-temperature and high-pressure cooking to make pulp. A large amount of sewage will be generated in the papermaking process, and if the sewage is discharged without treatment, it will seriously pollute the environment and water quality resources. Therefore, sewage needs to be treated before it can be discharged. [0003] The patent number is CN105771380B, a kind of sewage filtration and decontamination device, including a filter pool body, one side of the filter pool body is provided with a filter water outlet tank, and the filter pool is provided with a drive mechanism to filter the sewage from the outside to the inside. And the output port at one end is rotatably connected to the water outlet ...
