Description
Technical field
The present invention relates to a kind of processing method of papermaking-method reconstituted tobaccos waste water, belong to technical field of waste water processing.
Background technology
As a result of the manufacture paper with pulp forming technique similar with traditional paper industry, 1 ton of papermaking-method reconstituted tobaccos production is often produced
Product about produce 30 ~ 60 tons of waste water.Wastewater discharge is big in papermaking-method reconstituted tobaccos production process, complicated component, colourity are high, chemistry
Oxygen demand is high, fibre suspension is more, fluctuation of concentration is larger, belongs to intractable high concentrated organic wastewater.
Papermaking-method reconstituted tobaccos biochemical tail water and RO concentrated water composite wastes are handled using Fenton process, need to first adjust wastewater pH to
Acidity, then a certain amount of green vitriol and hydrogen peroxide are added into waste water, wastewater pH is adjusted after stirring a period of time to alkali
Property, certain weight polyacrylamide stirring a period of time is added into waste water, filtering is finally staticly settled.Chroma in waste water after processing
It can only be reached with COD《Urban wastewater treatment firm pollutant emission standard（GB 18918-2002）》Secondary standard（Colourity≤
40, COD≤100 mgL-1）.
Bodied ferric sulfate is a kind of molysite class inorganic polymer flocculant, without nuisances such as aluminium, chlorine and heavy metal ion
The aqueous phase transfer of matter, also non-iron-ion, it is with low cost, it is safe and reliable, it is widely used in Industrial Wastewater Treatment.
Potassium ferrate is extremely strong oxidant, collection oxidation, absorption, flocculation, precipitation, sterilizing, sterilization, decolourize, deodoriging properties
It is new, efficient, the nontoxic multifunctional water treating agent of the class received much attention in one.Activated carbon has physical absorption, chemistry
The characteristics such as absorption, oxidation, catalysis and reduction, are mainly used in adsorbing in terms of water process, decolourize, deodorization.
Contain substantial amounts of functional group on the strand of polyacrylamide and its derivative, with good water-soluble, wadding
Solidifying ability and adsorption bridging ability, while having that molecular weight is high, stability is good, having a wide range of application, usage amount is few and the dirt that produces
The features such as mud is few, extensively using the processing of all kinds polluted-water.However, utilizing bodied ferric sulfate, potassium ferrate, activated carbon
It is coagulant with polyacrylamide, is used in conjunction with coagulating treatment papermaking-method reconstituted tobaccos waste water and has not been reported.
The content of the invention
Present invention aims at a kind of processing method of papermaking-method reconstituted tobaccos waste water is provided, this method is easy to operate, place
The reason used time is short, high treating effect.
A kind of processing method of described papermaking-method reconstituted tobaccos waste water, step is as follows：
（1）Bodied ferric sulfate is added into waste water, and stirs 3 ~ 10 min；
（2）To step（1）Potassium ferrate is added in gained waste water, and stirs 3 ~ 10 min.
（3）To step（2）Activated carbon is added in gained waste water, and stirs 3 ~ 10 min；
（4）To step（3）Polyacrylamide is added in gained waste water, and stirs 3 ~ 10 min；
（5）By step（4）Gained waste water stands and filtered after a period of time.
Step（1）Described in bodied ferric sulfate consumption be 1500 ~ 3000 mg/L, mixing speed be 100 ~ 500 r/min.
Step（2）Described in potassium ferrate consumption be 50 ~ 500 mg/L, mixing speed be 100 ~ 500 r/min.
Step（3）Described in activated carbon dosage be 100 ~ 1000 mg/L, mixing speed be 100 ~ 500 r/min.
Step（4）Described in polyacrylamide be mass concentration 0.5 ‰ solution, consumption be 1 ~ 3 mL/L, mixing speed
For 100 ~ 500 r/min.
It is used as the preferred technical solution of the present invention：
（1）2750 mg/L bodied ferric sulfates are added into waste water, and 3 min are stirred with 300r/min；
（2）To step（1）150mg/L potassium ferrates are added in gained waste water, and 3 min are stirred with 300r/min.
（3）To step（2）1100mg/L activated carbons are added in gained waste water, and 3 min are stirred with 300r/min；
（4）To step（3）1mg/L polyacrylamides are added in gained waste water, and 3 min are stirred with 300r/min；
（5）By step（4）Gained waste water stands and filtered after a period of time.
Compared with Fenton process, beneficial effects of the present invention：
The present invention utilizes bodied ferric sulfate, potassium ferrate, activated carbon and the life of polyacrylamide coagulating treatment papermaking-method reconstituted tobaccos
Change tail water and RO concentrated water composite wastes.In During Coagulation Process, bodied ferric sulfate is mainly by compression double electric layer, absorption electricity
Caught with, sedimentation screen and volume is swept etc. that mechanism works, make biochemical tail water and tiny suspended particulate and glue in RO concentrated water composite wastes
Body particle is de- steady, is gathered into thicker particle precipitation.Potassium ferrate mainly plays oxidation, its Fe generated after decomposing
(OH)3Play flocculation.Activated carbon plays absorption, catalysis, decolorization, while activated carbon granule can be used as the bone for forming flco
Frame, improves in coagulation process that the alumen ustum that produces is loose, is difficult the situation sunk, make the flco to be formed closely knit and have preferable sedimentation
Performance.Polyacrylamide mainly plays absorption, built bridge and Coagulation aiding.Papermaking-method reconstituted tobaccos biochemical tail water is handled using this method
With RO concentrated water composite wastes, easy to operate, the processing used time is short, and high treating effect, chroma in waste water and COD after processing can reach
《Urban wastewater treatment firm pollutant emission standard（GB 18918-2002）》One-level A standards（The mg of colourity≤30, COD≤50
L-1）.
