Description
Technical field
The present invention relates to technology for the treatment of of papermaking wastewater fields, used more particularly to a kind of clean paper making sewage treatment
Filter device.
Background technique
Paper industry is that the industries such as packaging, printing and news information provide basic raw material, with non-in national economy
Normal consequence and very big development space will be with states of China especially using paper and cardboard as the raw material of consumption-orientation
People's expanding economy remains vigorous demand.Many with water in paper making process, producing 1 ton of paper about needs water 300-500
Cubic meter, while paper-making process can generate a large amount of waste water.Currently, China's pulp and paper industry quantity of wastewater effluent is located at national sewage
The third position of total emission volumn, chemical oxygen consumption (COC) is located at first of national total emission volumn in sewage effluent.
Two production processes of slurrying and copy paper of paper waste in paper industry production, slurrying are plant original
Fiber separation in material comes out, and slurry is made, then through bleaching, this process can generate a large amount of paper waste；Copy paper is slurry
Material dilution, molding, squeezing and drying, so that paper be made, this process can also generate paper waste.The papermaking that slurrying generates is useless
Water, pollutes the most serious, and discharge waste water is in dark brown, referred to as Heisui River when pulp washing, and pollutant concentration is very high in Heisui River, containing a large amount of
The paper waste of fiber, inorganic salts and pigment, bleaching process discharge also contains a large amount of acid-base material.The papermaking of paper machine discharge
Waste water is known as plain boiled water, wherein containing a large amount of fibers and the filler and sizing material that add in process of production.
In the plain boiled water of paper waste, not only containing the paper making raw material that is largely lost, but also containing a large amount of chemicals and
Other impurities, such as paper pulp fiber.If do not recycled to paper pulp fiber, there will be a large amount of paper pulp fiber to enter sewage treatment system
In system, the treatment effect of sewage disposal system is seriously affected, while paper pulp being caused to waste, is not energy-saving and environment-friendly.
The patent application document of Publication No. 107670395A discloses a kind of sewage treating machine for paper making equipment, adopts
With water tank type device, after being filtered by natural sedimentation, then plus cationic polyacrylamide processing water in COD, BOD.But the dirt
