Description
Technical field
The present invention relates to technical field of sewage, the special inexpensive sewage-treating agent of specifically a kind of dyeing waste water and
Its preparation method.
Background technology
At present, China's water resource receives pollution in various degree, and situation is also constantly being aggravated.Especially in recent years, spin
Knit industry development rapid, its yield and quality have and greatly improve, it has also become China's water consumption is maximum, waste discharge amount is most
One of industrial department, and direction of the use of dyestuff also just towards anti-light solution, the degraded of anti-oxidant and antibiont is developed.With spinning
Weaver's industry is developed rapidly, and the kind and quantity of dyestuff increasingly increase, and DYE PRODUCTION and dyeing waste water have become the weight of water environment
One of point pollution source, is also a great problem of the current urgent need solution of field of water pollution control both at home and abroad.According to statistics, in DYE PRODUCTION
During, often produce 1 ton of dyestuff, with waste water loss 2% dye product, and in waste water remaining dye component, even if
Concentration is very low, enters the reduction that water body will also result in water body light transmittance, and the destruction of water ecosystem is most caused at last.
Conventional administering method has recycling and harmless treatment.Recycle:(1) waste water can be distinguished by water quality characteristicses
Recycle, such as the shunting of bleaching boiled-off waste water and dyeing and printing waste water, the former can be washed with convection current.Multi-purpose water, the row of reduction
High-volume；(2) recycle of alkali liquor is utilized, and is generally reclaimed using evaporation, and such as alkali lye amount is big, can be reclaimed with triple effect evaporation, and alkali lye amount is little,
Can be reclaimed with thin film evaporation；(3) dyestuff is reclaimed, and such as intellectual circle's dyestuff is acidificable becomes hidden bar acid, in colloidal particles, is suspended in raffinate
In, recycle Jing after precipitation is filtered.
Mainly there are bioanalysis, electrolysis, chemical method and photocatalytic method in the existing processing method for processing dyeing and printing sewage.It is biological
Method floor space is big, and narrow application range, effect is also undesirable；Although electrolysis effect is better than bioanalysis, energy resource consumption is big,
Difficulty.Photocatalytic method is got most of the attention due to making organic matter permineralization without secondary pollution, but photocatalytic method
For precipitating, suspension is still effective, and unsatisfactory for the effect for reducing COD, BOD and colourity, particularly deodorizing effect
It is worse, can additionally bring secondary pollution, it is impossible to fundamentally solve pollution problem.Chemical treatment method is with the chemistry thrown in
Agent treatment pollutant, including the reaction such as neutralization, flocculation, redox, it is more thorough that this mode processes sewage, energy after process
Enough reach discharge standard.Sewage-treating agent is then the primary raw material of method of chemical treatment.At present, it is domestic to be used at dyeing industrial sewage
Reason agent has a lot, but relatively costly, and process and the technological process of purification sewage are loaded down with trivial details, and treatment effect has much room for improvement.
