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 commercial production industry of rich and influential family, more should carry out the reduction of discharging of water for industrial use, improve the cyclic utilization rate of water, it is to avoid water for industrial use
Waste.
Meanwhile, problem of environmental pollution is also on the rise, and boosts environmental awareness, and reduces pollutant, especially industrial
The discharge of sewage or waste water, is to cause one of major reason of environmental pollution, how to process trade effluent or the discharge of waste water becomes
For reducing important measures of environmental pollution.
Paper industry is the serious industry of a polluted source discharge, and paper-making process needs using substantial amounts of water, traditional
A large amount of polluted sources are discharged in paper mill, all can produce pollution to water quality and soil, also produce substantial amounts of niff.Papermaking
Containing the paper-making fibre remaining in paper-making process in waste water in the waste water of factory's discharge, cause loss and the waste of paper-making fibre；
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 cannot eliminate for a long time in the environment.
The whole production process of pulp and paper industry needs substantial amounts of water, and these water summarize substantial amounts of in process of production
Industrial harmful substance, both cannot directly utilize, and directly discharge pollutes the environment again, and therefore, to pulping and papermaking processes, each stage produces
Raw waste water carries out recycling, has significant economy and social value, decides the survival and development of papermaking enterprise.
In paper industry, be usually used chemical precipitation, air-flotation process and biological oxidation etc. place method to sewage or
Wastewater treatment.
Papermaking environmental protection coagulation traditional handicraft is first precipitation or materialization flocculation sediment at present, flocculation process removal efficiency
Height, especially can remove the mailing pollutant of a large amount of macromolecule difficult degradations, and this carries out biochemical treatment for next step and has established base
Plinth, however, such process is only applicable to the relatively low waste water of load.European countries are the most advanced on materializing strategy, substantially
Superseded horizontal sedimentation tank, rushes the advanced sedimentation such as depositing reservoir, sludge blanket clarifier using milk.
The technology of biomembrane ultra-filtration in recent years, reverse osmosiss, electrodialysiss, ion-exchange treatment means continuously emerge.In papermaking
In industry, on the one hand because processing cost is too high, on the other hand due to the complicated component of paper waste, intractability is big, therefore,
So far industrialized maturation treatment technology is not still had to can use.
Inventor finds Patent No. 2009100012718 through retrieval, and patent name is the processing method of paper waste
Patent of invention disclose by filtration, upcb process, biochemical treatment, and the pulping wastewater treatment method of advanced treating, its
Inventive point is to employ upcb handling process, and achieving the goal is with the cost of relatively low waste water, and the treatment effeciency of waste water is high, and
And gratifying result can be reached.The present invention does not account for Bubble-floating Method, and a kind of water treatment effect is fine, and cost is not
High handling process, the requirement control parameter of upcb handling process is extremely complex, there is very big very difficult reality in commercial Application
An existing difficult problem.
Inventor also retrieves a Patent No. 2009100012703, and patent name is the processing method of paper waste
Patent of invention, which disclose using filtration, flocculation sediment, qa2o process, and advanced treating, the inventive point of this patent
It is that processing handling process using qa2o replaces conventional biochemical processing method, reaches cost-effective, high treating effect, technique letter
Single beneficial effect.But such technique needs using substantial amounts of chemical agent, in residual waste water after treatment, for useless
Reusing of water brings a lot of restricted problems.
And two patents all do not account for the fiber recovery problem in waste water, waste the fiber in waste water.
Content of the invention
In order to solve above-mentioned problem, 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 sedimentation, is a kind of wastewater treatment mode of more low consumption, can reach reason
The pulping wastewater treatment effect thought.

Also there is the removal of certain degree Deng pollution, then through second flocculating sedimentation, the dirt such as cod, bod in removal waste water further
Dye, improves the limpid degree of waste water, allows the harmful substance contents of waste water to reduce；
5th, biodegradation can remove the abnormal smells from the patient that waste water embarrasses, and improves the limpid degree of waste water, remove and be not flocculated sedimentation
The polluter getting off, allows waste water be finally reached the standard of paper machine room recycle-water.
Beneficial effects of the present invention:
(1) pollution, the harmful substance such as main ss, cod, bod being removed by flocculating sedimentation in waste water, power consumption is low, processes
Process is gentleer, and the requirement to equipment is low；
(2) waste water, after first flocculating sedimentation, eliminates most ss, then carries out fiber recovery, waste water pair
The injury of fiber recovery equipment is little, and the fiber that recovery obtains is cleaner, and purity is high, advantageously reduces the paper-making fibre of recovery
In pulping process when reusing, the amount of bringing into of pollutant；
(3) second flocculating sedimentation processes the waste water that the upper strata waste water obtaining is after the clean process of comparison, can be direct
After being transported to biodeposition pond, reach recycle water standard through biodeposition, second flocculating sedimentation processes the middle level obtaining and gives up
Water is the pollutions such as cod, bod, the water layer of harmful substance Relatively centralized, is transported to first flocculating sedimentation pond, is flocculated place again
Reason, improves the effect of the process of waste water；
(4) first flocculating sedimentation process the mud settling down processing with second flocculating sedimentation and enter sludge-tank,
In sludge-tank, the harmful substance in mud is processed further so that the material being settled down reaches environmental emission mark
Accurate.
