Abstract
The invention belongs to the technical field of wastewater processing, and specifically relates to a flocculant for treating papermaking wastewater. The flocculant for treating papermaking wastewater is composed of the following raw materials: polymerized chlorinated ferric sulfate, starch-acrylamide grafted polymer, tannin, and bentonite, and has the advantages of good processing effect on papermaking wastewater, no containing of aluminum element, safety, and environment-friendliness.
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 China people economic activity is day by day frequent, the pollution that 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, the macromole natural organic matter that also contains 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 all contains aluminium element, and aluminium element has very big harm to human body.
It is raw material that paper industry is used timber, straw, reed, rag etc., through High Temperature High Pressure boiling, isolates Mierocrystalline cellulose, makes paper pulp.The non-cellulose of finally discharging in raw material in process of production, partly becomes black liquid.In black liquor, contain xylogen, Mierocrystalline cellulose, VFA etc., frowziness, contaminative is very strong.The paper waste that slurrying produces, pollutes the most serious.During pulp washing, discharge waste water and be chocolate, be called Heisui River, in Heisui River, Pollutant levels are very high, and BOD, up to 5-40g/L, contains a large amount of fibers, inorganic salt and pigment.The paper waste that bleaching process is discharged also contains a large amount of acid-base materials.The paper waste that paper machine is discharged, is called plain boiled water, the filler and the sizing material that wherein contain a large amount of fibers and add in process of production.
Summary of the invention
The object of the invention is to for the defect of above-mentioned existence and a kind of flocculation agent for the treatment of paper waste is provided, the treatment effect that this flocculation agent is directed to paper waste is good, does not contain aluminium element, Environmental Safety.
Technical scheme of the present invention is: a kind of flocculation agent for the treatment of paper waste, is comprised of the raw material of following weight part:
The described flocculation agent for the treatment of paper waste, is comprised of the raw material of following weight part:
The described flocculation agent for the treatment of paper waste, is comprised of the raw material of following weight part:
The described flocculation agent for the treatment of paper waste, is comprised of the raw material of following weight part:
The described flocculation agent for the treatment of paper waste, is comprised of the raw material of following weight part:
Beneficial effect of the present invention is: flocculation agent of the present invention has the characteristic of efficient and wide spectrum, and its pH scope that adapts to water quality is wide, and pH value all has good effect in 5～12 scopes, flocculate precipitate is tight, settling velocity is fast, easily clarifies layering, and in the water after processing, salinity is few.
Adopt flocculation agent Processing Paper Wastewater of the present invention, waste water total soluble matter concentration after processing is 17～20mg/L, and total suspended matter is 1.0～1.5mg/L, and BOD has reduced by 89.5%～93.15%, COD has reduced by 80%～85.5%, and pollutants removal rate is 89.55%～92.35%.
