Description
Technical field
The present invention relates to tannic acid Wastewater Treatment, more particularly to a kind of place that wastewater membrane is produced for tannic acid
Reason system.
Background technology
A kind of tannin that tannic acid is obtained in Chinese gall, be yellow or light brown lightweight without crystalline substance powder or scale,
Have special micro- smelly, taste is extremely puckery, is dissolved in water and ethanol, is soluble in glycerine, is practically insoluble in ether, chloroform or benzene.Its aqueous solution with
Iron salt solutions, which meet, becomes black-and-blue, plus sodium sulfite can delay discoloration.Industrially, tannic acid is widely used in tanning and system
Blue ink is made, tannic acid can make protein coagulating.People are chemically treated raw pig skin, greenhide with tannic acid, can make life
In skin soluble protein solidification, then, put originally several days will smelly rotten rawhide, become beautiful, clean, soft
Tough, long-lived leather.
Production process of tannic acid is complicated, a large amount of waste water is produced in process of production, if being directly discharged to river course or underground
In water, black will be produced with heavy metal contact, environmental administration forbids such direct discharging of waste water, and tannic acid is in production process
In, part tannic acid is remained in waste water discharges together, the waste and environmental pollution for causing tannic acid to produce.
The content of the invention
Not only effective tannic acid composition in waste water can again be extracted, increased it is an object of the invention to provide a kind of
Tannin acid yield, and the waste water discharged also complies with the processing system that tannic acid produces wastewater membrane that is used for of national wastewater discharge standard
System.
A kind of processing system that wastewater membrane is produced for tannic acid of technical solution of the present invention, including：Wastewater disposal basin, pretreatment
Device, milipore filter concentration systems, tannic acid recovery system, waste water circulation filtration system.The waste water circulation filtration system is successively
It is connected provided with circulatory pool, regulating valve, booster pump, pressure gauge, and with the entrance of pretreatment unit.The milipore filter is polyacrylonitrile
Film, molecular cut off is 100000.
It is preferred that, set active carbon filter in the pretreatment unit.
It is preferred that, booster pump, pressure gauge, flowmeter, thermometer and milipore filter are provided with the milipore filter concentration systems.
It is preferred that, regulating valve, booster pump, evaporator, microwave dryer and tannin are provided with the tannic acid recovery system
Sour collection device.
The present invention produces the beneficial effect of the processing system of wastewater membrane for tannic acid：
A kind of processing system that wastewater membrane is produced for tannic acid of the present invention, tannic acid is filtered out by using pretreatment unit
Large granular impurity in waste water, alleviates the live load of next step milipore filter concentration systems.Concentrated by using milipore filter and be
System extracts the tannic acid in waste water again, and is evaporated dry direct finished product by tannic acid recovery system, improves
Production efficiency.By using waste water circulation filtration system again by the clarified solution ultrafiltration membrane treatment after concentration, further concentration
Extract, improve the recovery rate of tannic acid.

Booster pump 9, pressure gauge 10, flowmeter 11, thermometer 12 and milipore filter 3, tannin are provided with carbon filter, milipore filter concentration systems
Regulating valve 13, booster pump 9, evaporator 5, microwave dryer 6 and tannic acid collection device 7 are provided with acid recovery system, it is described useless
Water circulation filtering system is sequentially provided with circulatory pool 4, regulating valve 13, booster pump 9, pressure gauge 10, and with the entrance of pretreatment unit 2
It is connected, the milipore filter is polyacrylonitrile film, and molecular cut off is 100000.
The tannic acid that is used for of the present invention produces the processing system of wastewater membrane when it is implemented, high-pressure pump 9 is by wastewater disposal basin 1
Tannic acid waste water is extracted out, and is delivered to pretreatment unit 2 and is pre-processed, the large granular impurity in removal waste water, after pretreatment
Waste water pass through milipore filter concentration systems in high-pressure pump 9 be delivered to milipore filter 3 carry out ultrafiltration concentration extract tannic acid concentration
Liquid and clarified solution, tannic acid concentrate are obtained after the evaporator 5 in tannic acid recovery system and microwave dryer 6 are handled
Finished product is fitted into tannic acid collection device 7, and gained clarified solution can carry out free regulation by regulating valve 13, can enter waste water
Circulated filter system carries out pretreatment and milipore filter concentration extraction again, further extracts tannic acid, can also pass through floss hole 8
It is expelled directly out.
