Waste water treatment device for papermaking

Abstract

The invention discloses a waste water treatment device for papermaking processing, which comprises a treatment pool body, a support frame is arranged above the treatment pool body, the support frame is connected with connection seats, and a motor is arranged between the connection seats. The output end of the motor is connected with a first rotating shaft, the first rotating shaft is provided with a driving gear, and both sides of the motor are provided with a second rotating shaft, and the second rotating shaft is connected to the supporting frame in rotation, and the second rotating shaft The bottom is fixedly connected to the drum. The flocculant is added to the drum through the reagent adding port, the driving gear is driven by the motor to drive the driven gear, and finally the drum is driven to rotate, and the reagent is thrown out through the small hole on the sleeve under the action of centrifugal force for stirring. After stirring The flocs fall into the bottom of the grid, and the heated flocs are more likely to coagulate. The invention can effectively recycle the fibrous solid matter in the papermaking wastewater, avoiding the waste of resources and saving the cost of papermaking.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for papermaking. 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. In the production process, the non-cellulose part of the raw material is finally discharged to become papermaking black liquor. The black liquor contains lignin, cellulose, volatile organic acids, etc., which has an odor and is highly polluting. It is difficult for the waste water of the paper industry to collect and utilize the fibrous solid matter in the waste water in the industry, and it will be discharged in a polluting manner, which is a waste of resources. Some use the precipitation method, but the precipitation effect is not ideal, so in Therefore, it is necessary to provide a wastewater treatment device for papermaking to s...

It is difficult for the waste water of the paper industry to collect and utilize the fibrous solid matter in the waste water in the industry, and it will be discharged in a polluting manner, which is a waste of resources. Some use the precipitation method, but the precipitation effect is not ideal, so in It is very necessary to provide a kind of waste water treatment device for papermaking processing to solve the above problems
