Description
Technical field
The present invention relates to a kind of papermaking wastewater treatment system of low consumption, belong to field of industrial waste water treatment.
Background technology
Water is Source of life, and global water shortage problem is increasingly severe, and using water wisely is advocated always, as with water
The industrial production industry of rich and influential family, should more carry out the emission reduction of industrial water, improve the cyclic utilization rate of water, avoid industrial water
Waste.
Meanwhile problem of environmental pollution is also on the rise, boost environmental awareness, reduce pollutant, it is especially industrial
The discharge of sewage or waste water, is the one of the major reasons for causing environmental pollution, how to handle the discharge of trade effluent or waste water into
For the important measures to reduce environmental pollution.
Paper industry is that a polluted source discharges serious industry, and paper-making process needs to use substantial amounts of water, traditional
A large amount of polluted sources are discharged in paper mill, can all produce pollution to water quality and soil, also produce substantial amounts of niff.Papermaking
Containing the paper-making fibre remained in paper-making process in waste water in the waste water of factory's discharge, the loss and waste of paper-making fibre are caused；
Also contain additive for paper making in the waste water in paper mill, most additive for paper making is not volatilizable, can remain in soil or
In sewage, discharge can cause the pollution that can not be eliminated for a long time in the environment.
The whole production process of pulp and paper industry needs substantial amounts of water, these water summarize largely in process of production
Industrial harmful substance, both can not directly utilize, and directly discharge pollutes the environment again, and therefore, pulping and papermaking processes each stage is produced
Raw waste water carries out recycling, has significant economy and social value, decides the survival and development of papermaking enterprise.
In paper industry, usually using chemical precipitation, air-flotation process and biological oxidation etc. prescription method to sewage or
Wastewater treatment.
The coagulation of papermaking environmental protection at present traditional handicraft for just precipitation or materialization flocculation sediment, flocculation process removal efficiency
Height, can especially remove the mailing pollutant of a large amount of macromolecule difficult degradations, this has established base to carry out biochemical treatment in next step
Plinth, however, such processing is only applicable to the relatively low waste water of load.European countries are the most advanced on materializing strategy, substantially
Horizontal sedimentation tank is eliminated, the advanced sedimentation such as clarifying basin, sludge blanket clarifier is rushed using milk.
The technology of biomembrane hyperfiltration in recent years, reverse osmosis, electrodialysis, ion-exchange treatment means continuously emerge.In papermaking
In industry, on the one hand since processing cost is too high, on the other hand due to the complicated component of paper waste, intractability is big, therefore,
So far still can use without industrialized ripe treatment technology.
Inventor has found Patent No. 2009100012718 by retrieval, and patent name is the processing method of paper waste
Patent of invention disclose by filtering, UPCB processing, biochemical treatment, and the pulping wastewater treatment method of advanced treating, its
Inventive point is to employ UPCB treatment process, and it is that the treatment effeciency of waste water is high with the cost of relatively low waste water to achieve the goal, and
And gratifying result can be reached.The present invention's does not account for Bubble-floating Method, and a kind of water treatment effect is fine, and cost is not
High treatment process, the requirement control parameter of UPCB treatment process is extremely complex, in the presence of very big it is difficult to real in commercial Application
Existing problem.
Inventor also retrieves a Patent No. 2009100012703, and patent name is the processing method of paper waste
Patent of invention, which disclose and utilize filtering, flocculation sediment, QA2O processing, and advanced treating, the inventive point of the patent
It is to replace conventional biochemical processing method using QA2O processing treatment process, reaches cost-effective, high treating effect, technique letter
Single beneficial effect.But such technique needs to use substantial amounts of chemical agent, remains in waste water after treatment, for useless
Reusing for water brings many restricted problems.
And two patents do not account for the fiber recovery problem in waste water, waste the fiber in waste water.
The content of the invention
Above-mentioned in order to solve the problems, such as, the invention discloses a kind of papermaking wastewater treatment system of low consumption, this waste water
Processing system makes full use of the waste water treatment process of flocculating setting, is a kind of wastewater treatment mode of more low consumption, can reach reason
The pulping wastewater treatment effect thought.

First all of Flocculating setting basins and all second Flocculating setting basins share a sludge-tank.
The present invention operation principle be：
1st, the paper waste of paper mill discharge is discharged into wastewater disposal basin first, and wastewater disposal basin is accepted and stores waste water, for follow-up
Treatment process extracts；
2nd, the paper waste come is extracted from wastewater disposal basin, it is substantial amounts of directly from containing in the paper waste in wastewater disposal basin
The pollutions such as SS, COD, BOD, harmful substance, this waste water enter first of Flocculating setting basin, by waste water increase flocculant and
Flocculation aid, strengthen waste water in pollutant, harmful substance flocculation, sedimentation, the discharge of poisonous waste to settle down to sludge-tank,
Further processing, the upper strata waste water of settlement treatment, into fiber recoverer；
3rd, the SS of the waste water handled by one of flocculating setting is largely reduced, and injury of the waste water to fiber recoverer can be big
Big to reduce, the purity and clean degree of the paper-making fibre of recycling are much higher, are conducive to the friendly long-time service of equipment；
4th, the SS in the waste water after fiber recoverer is handled and paper-making fibre substantially reduce, COD, BOD in waste water
Also there is the removal of certain degree Deng pollution, then by second flocculating setting, the further dirt such as COD, BOD in removal waste water
Dye, improves the limpid degree of waste water, allows the harmful substance contents of waste water to reduce；
5th, it is biodegradable to remove the smell that waste water embarrasses, the limpid degree of waste water is improved, removal is not flocculated sedimentation
The polluter to get off, allows waste water to be finally reached the standard of paper machine room recycle-water.
Beneficial effects of the present invention：
（1）Pollution, the harmful substances such as SS, COD, BOD in waste water are mainly removed by flocculating setting, energy consumption is low, processing
Process is gentleer, and the requirement to equipment is low；
（2）Waste water eliminates most SS after first of flocculating setting, then carries out fiber recovery, waste water pair
The injury of fiber recovery equipment is small, and the fiber that recycling obtains is cleaner, and purity is high, advantageously reduces the paper-making fibre of recycling
In pulping process when reusing, the amount of bringing into of pollutant；
（3）The upper strata waste water that second flocculating setting is handled is the waste water after the clean processing of comparison, can be direct
After being transported to biological setting basin, reach recycle water standard by biodeposition, the middle level that second flocculating setting is handled is given up
Water is the pollutions such as COD, BOD, the water layer of harmful substance Relatively centralized, is transported to first of Flocculating setting basin, is flocculated place again
Reason, improves the effect of the processing of waste water；
（4）The sludge to settle down of first of flocculating setting processing and the processing of second flocculating setting enters sludge-tank,
Further the harmful substance in sludge is handled in sludge-tank so that the material to settle down reaches environmental emission mark
It is accurate.
