Abstract
The invention discloses a kind of fur nitre dye wastewater utilization technique, process (containing twice physical decolorization) → ion-exchange treatment → film including routine biochemistry and process；Described routine biochemistry processes and adds high-efficient decolorizing flocculant decolouring respectively when two-stage precipitation, adds activated carbon adsorption decolouring when biochemistry pool processes；After routine biochemistry process terminates, carry out ion-exchange treatment and reduce hardness of water, finally carry out film process；Described film processes and is separated by sewage, and concentrated solution is according to its low colourity, soft, high salinity feature, and being back to taw respectively needs to use the operation of salt, and treatment fluid is limpid according to its water quality, the feature of soft, is back to dyeing process.Utilizing the fur that reuse liquid and concentrated solution taw are dyeed out, indices all can reach Industry code requirements, with normal commercial by water base indifference；In addition pollutant emission, saving water resource are reduced.
Description
Technical field
The present invention relates to fur field of waste water treatment, specifically a kind of fur nitre dye wastewater utilization technique.
Background technology
Producing substantial amounts of waste water in the fur course of processing, these waste water contain heavy metal, neutral salt, higher colourity and relatively
High COD, can reach discharge standard through simple physics, biochemical treatment, but, these water directly emit and can cause water
A large amount of wastes of resource, are unfavorable for sustainable development.In prior art, can use common advanced treatment method for sewage water make through
Cross simple physical, the fur processing waste water of biochemical treatment reaches fur job shop water supply standard, but, at these sewage deeps
There is the problem that operating cost is high in reason method.Water the most after treatment has part to be unfavorable for the composition that nitre contaminates, such as hardness salt
Degree etc..
Summary of the invention
The present invention is to solve defect and deficiency that above-mentioned prior art exists, it is provided that a kind of fur nitre dye waste water is comprehensive
Utilize technique, the low cost waste water treatment, recovery and utilization that conventional coloured sewage disposal technology combines, this work with membrane technology
Skill utilizes Conventional waste water to process technique and combines physics decolouring technology, combines with membrane technology, it is to avoid the high-end dirt of simple use
The high operation cost that water technology brings；Waste water after process can be directly used for taw and dyes each different operations, it is achieved
Water-saving and environmental protection, reduces pollutant emission, the purpose of resource reusing.
The technical scheme is that and be achieved in that: a kind of fur nitre dye wastewater utilization technique, including following step
Rapid:
1) nitre dye waste water is carried out routine biochemistry process: sewage is adjusted pond and enters first stage precipitation tank, then through two-stage precipitation
Pond also utilizes flocculant to decolour, then through biochemistry pool biochemical treatment and utilize activated carbon again to decolour, it is achieved reduce the ammonia in sewage
Nitrogen, COD, colourity；
2) nitre after biochemical treatment is contaminated waste water and process the hardness reduced in sewage through ion exchanger；
3) after film processes, obtain two parts again: treatment fluid and concentrated solution, wherein concentrated solution be used for soaking, defat, leaching
Acid, softening, tanning, comprise the salt of high concentration, and above-mentioned taw operation itself to be put into a certain amount of salt and be protected in concentrated solution
Tannage, therefore concentrated solution reclaims for taw；
4) treatment fluid processed through film is used for fur dyeing.
As preferably, described flocculant is Wei Shibang high-efficient decolorizing flocculant VBT-01.
Have employed technique scheme the invention have the advantage that Conventional waste water processes technique and combines physics decolouring technology,
Combine with membrane technology, it is to avoid the simple high operation cost using high-end sewage disposal technology to bring；Giving up after process
Water can be directly used for taw and dyes each different operations, it is achieved water-saving and environmental protection, reduces pollutant emission, the purpose of resource reusing.
Detailed description of the invention
The detailed description of the invention of the present invention is as follows:
Embodiment 1:
A kind of fur nitre dye wastewater utilization technique, comprises the following steps: 1) nitre dye waste water is carried out at routine biochemistry
Reason: sewage is adjusted pond and enters first stage precipitation tank, then through second-level settling pond and utilize flocculant to decolour, then at biochemistry pool biochemistry
Manage and utilize activated carbon again to decolour, it is achieved reducing the ammonia nitrogen in sewage, COD, colourity；2) nitre after biochemical treatment is contaminated waste water
The hardness reduced in sewage is processed through ion exchanger；
3) after film processes, obtain two parts again: treatment fluid and concentrated solution, wherein concentrated solution be used for soaking, defat, leaching
Acid, softening, tanning, comprise the salt of high concentration, and above-mentioned taw operation itself to be put into a certain amount of salt and be protected in concentrated solution
Tannage, therefore concentrated solution reclaims for taw；4) treatment fluid processed through film is used for fur dyeing.Described flocculant is prestige scholar
Nation high-efficient decolorizing flocculant VBT-01.
Above-mentioned technology utilization Conventional waste water processes technique and combines physics decolouring technology, combines with membrane technology, it is to avoid
The simple high operation cost using high-end sewage disposal technology to bring；Waste water after process can be directly used for taw and dyes each
Different operations, it is achieved water-saving and environmental protection, reduce pollutant emission, the purpose of resource reusing.
