De- soil）Addition be that every liter of waste water plus 140 ~ 160g, the addition of the hectorite（It is scaled purity 100%）It is every liter to give up
Water adds 120 ~ 140g.
As the implementation method of optimization, step（2）In, the method for the two-stage flocculation sediment treatment is that regulation is arrived into weak
The gallic acid production wastewater of alkalescence imports one-level flocculation sedimentation tank, and nano hydrogel material is added in one-level flocculation water,
Stirring and adsorbing, precipitation, by sediment press filtration, are combined into two grades of flocculation basins by precipitation waste water and press filtration waste water afterwards, add and receive
Rice hydrogel material, is stirred absorption, precipitation again, merges sediment.
As the implementation method of optimization, step（2）In, two-stage flocculation sediment treatment adsorption time be respectively 3 ~ 4 hours,
Sedimentation time is distinguished 2 ~ 3 hours.
As the implementation method of optimization, step（2）In, the montmorillonite or alumino-silicate（It is scaled the illiteracy of purity 100%
De- soil）Addition be that every liter of waste water plus 140 ~ 160g, the addition of the hectorite（It is scaled purity 100%）It is every liter to give up
Water adds 120 ~ 140g.
As the implementation method of optimization, step（2）In, the waste water that will be postponed at nano hydrogel material, through nanofiltration membrane system
System desalination.Wherein, nanofiltration dislysate is directly discharged after then being processed into biochemistry pool, nanofiltration concentrate（Do not dialyse part）Then lead to
Cross multi-effect evaporator concentration, crystallization and obtain solid sodium chloride.
As the implementation method of optimization, step（3）In, 1% ~ 2%, the pH of system is after wash-out for the NaOH concentration control
9~11。
The present invention is processed waste water containing gallic acid with hectorite, montmorillonite or alumino-silicate hydrogel, a side
Face can reduce waste water COD, by desorption process can be in high efficiente callback waste water most of gallic acid, provide high added value
Source is recycled.On the other hand waste water has been carried out to adsorb-clarifying treatment, has significantly reduced waste water color and luster.Water-setting glue material
Material belongs to inorganic material, is avoided that waste discharge because using may contaminated risk again organic reagent.With reference to NF membrane
Separate and " anaerobic-aerobic " biochemical processing, gallic acid production wastewater may ultimately reach first discharge standard.The present invention
There is environmental protection, energy consumption, reduces cost, resource recycling is reduced and simplify operation.
