Description
Technical field
The present invention relates to a kind of papermaking wastewater treatment systems 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, and boosts environmental awareness, and reduces 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 at
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 a large amount of water, traditional
A large amount of polluted sources are discharged in paper mill, can all generate pollution to water quality and soil, also generate a large amount 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 entire production process of pulp and paper industry needs a large amount of water, these water to summarize in process of production largely
Industrial harmful substance both can not be utilized directly, and direct emission pollutes the environment again, therefore, be produced to pulping and papermaking processes each stage
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 traditional handicraft of papermaking environmental protection at present is first precipitation or materialization flocculation sediment, flocculation process removal efficiency
Height can especially remove a large amount of macromolecules mailing pollutant difficult to degrade, this has established base to carry out biochemical treatment in next step
Plinth, however, such processing is only applicable to the lower 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 available without industrialized ripe treatment technology.
Inventor has found that Patent No. 2009100012718, patent name are the processing method of paper waste by retrieval
Patent of invention disclose the pulping wastewater treatment method by filtering, UPCB processing, biochemical treatment and advanced treating,
Inventive point is to use UPCB treatment process, and it is with the cost of lower waste water to achieve the goal, and the treatment effeciency of waste water is high, and
And satisfactory 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
The requirement control parameter of high treatment process, UPCB treatment process is extremely complex, and there are prodigious 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 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 advantageous effect.But such technique needs to use a large amount of chemical agent, in the waste water that remains in that treated, 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.
Invention content
Above-mentioned in order to solve the problems, such as, the invention discloses a kind of work sides of the papermaking wastewater treatment system of low consumption

Process is milder, 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 layer waste water that second flocculating setting is handled is clean treated the waste water 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 useless
Water be the pollutions such as COD, BOD, harmful substance Relatively centralized water layer, be transported to first of Flocculating setting basin, be flocculated place again
Reason, improves the effect of the processing of waste water;
(4)The sludge of first of flocculating setting processing and the processing of second flocculating setting to settle down enters sludge-tank,
Further the harmful substance in sludge is handled in sludge-tank so that the substance to settle down reaches environmental emission mark
It is accurate.
