Description
Technical field
The present invention relates to a kind for the treatment of system of paper waste, belong to sewage treatment area.
Background technology
Water is Source of life, and global water shortage problem is more and more serious, and water saving is advocated always, as the industrial production industry with water rich and influential family, more should carry out the reduction of discharging of process water, improves the cyclic utilization rate of water, avoids the waste of process water.
Meanwhile, problem of environmental pollution is also on the rise, and boosts environmental awareness, decreasing pollution thing, the discharge of especially industrial sewage or waste water is one of major reason causing environmental pollution, and the discharge how processing industrial sewage or waste water becomes the important measures reducing environmental pollution.
Paper industry is that a polluted source discharges serious industry, and paper-making process needs to use a large amount of water, and a large amount of polluted source is discharged in traditional paper mill, all can produce pollution, produce a large amount of nifves in addition to water quality and soil.Containing the paper-making fibre remained in paper-making process in waste water in the waste water of paper mill discharge, cause loss and the waste of paper-making fibre; Also containing additive for paper making in the waste water in paper mill, most additive for paper making is not volatilizable, can remain in soil or sewage, and discharge can cause the pollution cannot eliminated for a long time in the environment.
The whole production process of pulp and paper industry needs a large amount of water, these water summarize a large amount of industrial objectionable impuritiess in process of production, both cannot directly utilize, direct discharge pollutes the environment again, therefore, recycling is carried out to the waste water that pulping and papermaking processes each stage produces, has significant economy and social value, decide the survival and development of papermaking enterprise.
In paper industry, usually use chemical precipitation, air-flotation process and bio-oxidation etc. prescribing method to sewage or waste water process.
Current papermaking environmental protection coagulation traditional technology is just precipitate or materialization flocculation sediment, flocculation process removal efficiency is high, especially the mailing pollutent of a large amount of polymer difficult degradation can be removed, this lays a good foundation for next step carries out biochemical treatment, but such process is only applicable to the lower waste water of load.European countries are the most advanced on materializing strategy, substantially eliminate horizontal sedimentation tank, adopt milk to rush the advanced precipitation technology such as settling pond, sludge blanket clarifier.
The technology of microbial film ultra-filtration in recent years, reverse osmosis, electrodialysis, ion exchange treatment means constantly occur.In paper 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 large, therefore, does not still have industrialized ripe treatment technology to use so far.
Through retrieval, contriver finds that the patent No. is 2009100012690, patent name is that the patent of invention of the treatment process of paper waste discloses by filtration, sand setting, flocculation sediment, and the pulping wastewater treatment method of separating and recovering step, its inventive point is before flocculation agent is added into and carries out flocculation sediment in pending middle water, desalting treatment is carried out to the flocculation agent accounting for total consumption 70-90% weight, achieving the goal is paper waste with lower one-tenth present treatment height salt content, and can reach gratifying result.Do not relate to the distillation process of sewage, and day is asked in the recovery of heat of distillation process, in industrial application, narrow and small according to there is Application Areas, the process of the paper waste of relative broad range can not be applicable to.
It is 2009100012703 that contriver also retrieves one section of patent No., patent name is the patent of invention of the treatment process of paper waste, which disclose and utilize filtration, flocculation sediment, QA2O process, and advanced treatment, the inventive point of this patent is to use QA2O process treatment process to replace conventional biochemical processing method, reach cost-saving, treatment effect is good, the simple beneficial effect of technique.But such technique needs to use a large amount of chemical agent, in residual waste water after treatment, and not reducing before the water yield of waste water after process and process, is a kind of method effectively can not isolating comparatively pure water.
