Description
Technical field
The invention belongs to the technical field of wastewater treatment, be specifically related to a kind of flocculation agent for the treatment of paper waste.
Background technology
Along with our people's economic activity is day by day frequent, the pollution caused water body by soil erosion, production and sanitary sewage is more and more serious, its pollutant component comprises lot of trace organic pollutant, heavy-metal pollution thing, macromole natural organic matter also containing higher concentration, single flocculation agent can not have been dealt with problems, and along with the enhancing of people's environmental consciousness, also more and more higher to the requirement of flocculation agent.Existing flocculation agent is all containing aluminium element, and aluminium element has high risks to human body.
Paper industry uses timber, straw, reed, rag etc. to be raw material, isolates Mierocrystalline cellulose, make paper pulp through High Temperature High Pressure boiling.In process of production, finally the non-cellulose part of discharging in raw material becomes black liquid.Containing xylogen, Mierocrystalline cellulose, VFA etc. in black liquor, frowziness, contaminative is very strong.The paper waste that slurrying produces, pollutes the most serious.During pulp washing discharge waste water be chocolate, be called Heisui River, in Heisui River, Pollutant levels are very high, BOD up to 5-40g/L, containing a large amount of fiber, inorganic salt and pigment.The paper waste that bleaching process is discharged is also containing a large amount of acid-base materials.The paper waste that paper machine is discharged, is called plain boiled water, wherein containing a large amount of fiber and the filler added in process of production and sizing material.
Summary of the invention
The object of the invention is to the defect for above-mentioned existence and provide a kind of flocculation agent for the treatment of paper waste, the treatment effect that this flocculation agent is directed to paper waste is good, not containing aluminium element, and Environmental Safety.
