Abstract
The utility model discloses waste water treatment equipment for deinking waste paper, which belongs to waste water treatment equipment for deinking waste paper and pulping. Waste water which contains oil and ink enters an aeration section of an aerator (1) from a water inlet (7), oil and ink particles in the waste water attach to air bubbles in the aeration section and float on a liquid surface, the oil and ink particles can be scraped in a sludge collecting tank (4) by a sludge scraping plate (3), and the sludge which contains oil and ink can be sucked out of the equipment by an exhaust fan (8). The treated waste water can be divided into two parts, one part is clear turbid liquid which contains few small fibers, the clear turbid liquid can be discharged out of the equipment through a water outlet (5) which is arranged on the tail of a tank body, and the part of waste water can be used for a spraying water faucet of a pulping process. The other part is thick turbid liquid which contains large numbers of small fibers and can be used for diluting slurry materials in the pulping process. Compared with the prior art, the utility model has the advantage of high efficiency.
Description
Technical field
The utility model relates to deinking pulp-making waste-water treatment facility, the equipment that deinking wastewater and ink particle wherein are separated, specifically a kind of deinking pulp-making waste-water treatment facility.
Background technology
The characteristics of waste paper deinking waste water are SS content height, and COD and BOD content are lower, the more important thing is wherein SS based on fiber fines, and tiny ink particle is time.Also contain the residual completely alkali of environmentally harmful unreacted, residual NaSiO in the waste water
3, H
2O
2, pharmaceutical chemicals and certain heat energy such as deinking agent.And deleterious to papermaking only be wherein ink particle, all the other materials are not only harmless but also useful to papermaking.Traditional water treatment mode is with its whole removals, and (fiber loss causes yield to reduce, and the use of acidic coagulant causes residual NaOH and NaSiO so not only to have improved the deinking cost
3Loss; The discharging of processed waste water has increased water loss and has run off contained heat energy etc. in the raw wastewater), and improved cost for wastewater treatment (need add pharmaceutical chemicalss such as a large amount of coagulating agent, flocculation agent because of traditional water treatment method) greatly at all solids and colloidal suspended substance.So study a kind of the ink particle of removing in the deinking wastewater, and don't remove wherein fiber fines and residual chemicals, thereby and the method for wastewater treatment that can utilize respectively the moisture level after handling, have important economic implications and environment protection significance.
Summary of the invention
The purpose of this utility model is to develop a kind of the ink particle of removing in the deinking wastewater, and don't removes wherein fiber fines and residual chemicals and can carry out the deinking pulp-making waste-water treatment facility of quality grading to processed waste water.
The utility model is achieved in that a kind of treatment facility of waste paper deinking waste water, contain printing ink waste water enters aerator (1) from water-in (7) aeration zone, ink particle in the waste water in the aeration zone attached to liquid level on the air filled cavity come-up, scraped in the mud receiving tank (4) by cleaning shoe (3), will contain outside the printing ink mud extraction equipment by vacuum fan (8).The waste water of handling is divided into two, and a part is for containing the pure and turbid liquid of a small amount of fiber fines, and outside the water outlet that is positioned at the casing afterbody (5) device for transferring, the spray water that this part waste water can be used for pulping process is chewed water.Another part is the dense liquid that contains a large amount of fiber fines, and this part waste water can be used for the dilution of pulping process slurry.
The utility model compared with prior art, it is low to have cost for wastewater treatment, processed waste water can all be distinguished utilization again, thereby makes fiber fines, residual chemical and heat energy in the raw wastewater all can obtain utilizing fully again, thus the advantage that reduces production costs greatly.
