Background technology
At present, the processing method of the industrial wastewater that the chemical field such as chlor-alkali, papermaking, plating produces 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.So-called
Zero-emission, for its content, on the one hand haves no alternative but the waste discharge produced, is reduced in production process to be controlled
Zero；On the other hand the garbage haveing no alternative but discharge is made full use of, finally stop the generation of non-renewable resources and the energy.Zero-emission
Discharge technique is integrated application membrance separation, evaporative crystallization or be dried etc. physics, chemistry, biochemical process, by miscellaneous for the solid in the middle of waste water
Matter is concentrated into very high concentration, and major part water has returned circulating and recovering, and remaining a small amount of water with solid waste can be by steaming
Send out/crystallize, evaporate/be dried, the approach such as waste material absorption processes and recycles, and does not discharge system.
In commercial production in the past frequently with processing method have multiple-effect evaporation after carry out sheeting or mist projection granulating with flaker
It is dried with fluid bed afterwards, but these methods generally require the substantial amounts of steam of consumption, electricity or coal homenergic, production cost
Height, and finally inorganic salt after evaporation is often with water of crystallization, and impurity content is higher, it is difficult to effectively utilize, final discharge
Waste water also is difficult to up to standard.
Industrial processes often contain in the waste water of discharge the inorganic salt of high concentration, particularly nothing in chemical process
With a large amount of inorganic salts produced in machine salt by-product or regulation solution acid alkalinity, inorganic salt in the waste water finally discharged all can be made
Concentration is higher.High-salt wastewater has discharge capacity big, strong toxicity, the feature that intractability is high.
For high salt organic waste water, although through pretreatment and biochemical treatment, but the most still contain a certain amount of
Organic substance, utilize above strong brine evaporation liquid zero emission device or process high-salt wastewater evaporation crystallization equipment to high salt
Waste water is evaporated crystallization, and obtained crystal salt includes substantial amounts of Organic substance, it is difficult to processes further and recycles, can only
Special filling up is carried out as solid waste.As a example by a certain medium-and-large-sized coal chemical industry enterprises, one produces 20 billion cubic meter coal systems per year
The enterprise of natural gas, the solid waste produced per hour is more than 3 tons, based on dangerous solid waste landfill per ton needs 3000 yuan
Calculating, annual landfill expense is 72,000,000 (running based on 8000 hours by annual), and this is for enterprise, can not bear.
