The water purifier is prepared by mixing sodium metabisulfite, ferrous sulfate, a curing agent, a pH value regulator and a catalyst. According to the water purifier, the cyclic water use rate can be improved; the water consumption and the wastewater emission are reduced; raw materials are easily available; the cost is greatly reduced; secondary pollution is not generated; and the environment is effectively protected.
Description
Technical field
The invention belongs to a kind of water purification agent, be specifically related to a kind of water purification agent for pulping wastewater treatment, belong to technical field of chemistry and chemical engineering.
Background technology
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.
Paper waste is mainly from the slurrying in paper industry production and copy paper two production processes.Slurrying is the fiber separation in plant material out, makes slurry, then through bleaching, this process can produce a large amount of paper wastes; Copy paper be pulp dilution, shaping, squeezing, dry, make paper, this process also easily produces paper waste.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.
Paper waste is the trade effluent that a kind of intractability is larger, generally by physico-chemical process+biochemistry, pollution substance is wherein degraded.Because the contained pollutent of waste water itself is very complicated, after treatment, though water outlet can reach emission standard substantially, but it is apart from each other with the requirement of waste water recycling to water quality, adopt the treatment process such as traditional sand filtration, activated carbon filtration, multi-medium filtering to realize waste water recycling process, just to a certain degree reduce water outlet concentration of suspension, soluble pollutants in sewage cannot be removed further as COD, ammonia nitrogen and salt grade, if reuse, can directly have influence on paper effect.The general reuse water of paper industry is often only limited to the slagging-off, pulp washing, rinsing etc. of the production process production technique not high to water quality requirement, and these workshop section's use water there are certain requirements indexs such as COD, turbidity, iron, existing filtering technique can not meet the water quality requirement of these workshop sections, and conventional multi-level filtration process have long flow path, floor space large, produce the shortcomings such as water water quality is unstable.Advanced Treated sewage reusing treatment process must be adopted, on the basis of original sewage qualified discharge, reduce iron, COD concentration in water further, on the one hand can directly as reuse water, for removing the gred, pulp washing, rinsing etc. the workshop section not high to water quality requirement; Middle water on the other hand after process, can directly pass through reverse osmosis or ion-exchange desalination, eliminates multistage security personnel filtration and ultrafiltration technology in reverse osmosis process, decreases pre-treatment expense, prolongation RO film work-ing life.
Pulping wastewater treatment should focus on and improve cycling use of water rate, reduces water consumption and wastewater discharge, also should try to explore various reliable, economical and can make full use of the method for wastewater treatment of useful resources in waste water simultaneously.Such as: fibering solid matter in the recyclable plain boiled water of flotation waste water facture, the rate of recovery can reach 95%, and primary water can reuse; Sodium hydroxide, sodium sulphite, sodium sulfate and other sodium salts with organism combination in the burning recyclable Heisui River of waste water treatment process.Neutralized wastewater facture regulates waste water ph; Coagulating sedimentation or flotation process can remove suspended solids in waste water; Chemical precipitation method can be decoloured; Biological treatment can remove BOD, more effective to kraft paper waste water; Wet oxidation process process sulfite paper pulp waste water is comparatively successful.In addition, pulping wastewater treatment methods such as adopting reverse osmosis, ultra-filtration, electrodialysis is also had both at home and abroad.
