Background technique
Currently, the processing method for the industrial wastewater that the chemical fields such as chlor-alkali, papermaking, plating generate mainly includes chemical precipitation
Method, oxidation-reduction method, membrane separation process and ion-exchange, but these traditional handicrafts are extremely difficult to the requirement of zero-emission.It is so-called
On the one hand zero-emission will control the waste discharge for haveing no alternative but generate in production process, be reduced to for its content
Zero；On the other hand the waste for haveing no alternative but discharge is made full use of, finally prevents the generation of non-renewable resources and the energy.Zero-emission
Discharge technique is integrated application UF membrane, and the physics such as evaporative crystallization or drying, chemistry, biochemical process are miscellaneous by the solid in waste water
Matter is concentrated into very high concentration, and most of water has returned to circulating and recovering, is left a small amount of water with solid waste, can pass through steaming
The approach processing such as hair/crystallization, evaporation/drying, waste material absorption recycle, without discharge system.
In industrial production in the past frequently with processing method have and carry out sheeting or mist projection granulating with flaker after multiple-effect evaporation
It is dried afterwards with fluidized bed, however these methods generally require to consume the energy such as a large amount of steam, electricity or coal, production cost
Height, and finally for the inorganic salts after evaporation often with the crystallization water, impurity content is higher, it is difficult to efficiently use, finally discharge
Waste water is also difficult up to standard.
Often containing nothing in the inorganic salts of high concentration, especially chemical production process in the waste water discharged in industrial processes
Machine salt by-product adjusts a large amount of inorganic salts in solution acid alkalinity and generated, can all make inorganic salts in the waste water finally discharged
Concentration is higher.High-salt wastewater has that discharge amount is big, strong toxicity, the high feature of processing difficulty.
