Description
Technical field
The present invention relates to a kind of processing method of beneficiation wastewater, belong to the field of waste water treatment in environmental protection.
Background technique
Mineral resources are the important material bases of human social development and the development of the national economy, and mining industry is that China's history is most long-drawn-out
Long industry, while being the basic industry of the national economic development again, it is related to agricultural, light industry, chemical industry, metallurgy, machinery, builds
Build, the energy, traffic, national defence and people's daily life multiple fields.As it can be seen that mining industry, which plays China's expanding economy, to be replaced
The important function in generation.However, mine needs a large amount of industrial water in recovery process, while giving off a large amount of waste water, this
The indices such as a little heavy metal ions in wastewater concentration, solid suspension concentration and COD, all considerably beyond country
Discharge standard, this is just easy to cause tremendous influence to dressing plant's surrounding enviroment.Moreover, from the purification of domestic and international beneficiation wastewater
From the point of view of disposal status, qualified discharge is handled beneficiation wastewater and is allowed to, not only processing technique difficulty is big, but also processing cost
It is very high.Therefore, how beneficiation wastewater is effectively treated, is China's mining industry important topic urgently to be resolved.
Various organic and Inorganic floatation medicine when main harmful substance is heavy metal ion, ore floatation in beneficiation wastewater
Agent, cyanide, cyanogen chromium complex etc. including severe toxicity.Also contain various undissolved coarse grain and fine particle impurity in waste water.Choosing
Contain the sulfate, chloride or hydroxide of sodium, magnesium, calcium etc. in mine waste water toward contact.Acid in beneficiation wastewater mainly contains
Sulfur mineral is mixed with water through air oxidation and is formed.
In all multi-pollutants of beneficiation wastewater, heavy metal ion pollutant be it is very important, as copper, lead, zinc, chromium,
The harm of mercury and arsenic plasma and its compound, is generally well known.Meanwhile it may be neglected by people there are also a metal ion species
Depending on, that is, barium ions.Although barium ions has harm very serious unlike above-mentioned several high toxicity heavy metal ion
Property, but if improvement is not added and is allowed to be emitted into surface water body environment, barium ions can be followed into nature food chain quickly
Ring, final still to be taken in and be absorbed by human body, less serious case cause nausea,vomiting,diarrhea, abdominal pain, body may occur when serious
Paralysis, facial livid purple, coldness of extremities, muscular tremor, twitch, lingualis and throat paralysis, or even aphasis occurs.
Currently, China is mainly the following processing method for the beneficiation wastewater containing heavy metal ion:
(1) neutralization precipitation method:
Neutralization precipitation method is the method for heavy metal ion comparative maturity in current treatment of acidic wastewater.This method can will be in waste water
Valuable metal ions form of a hydroxide under different pH value conditions is precipitated out, and achievees the purpose that recycling.Neutralizer
Lime stone or lime are mainly used, also there are Some Enterprises using alkaline waste liquor or waste residue (flyash, gangue, carbide slag, lime
Slag etc.) neutralize acid waste water.This method has many advantages, such as that technically simple easy, primary construction investment is lower, operation and maintenance are convenient,
But the disadvantage is that treatment effect is not ideal enough, effluent index is unstable, it is secondary to be easily caused in treatment process using a large amount of neutralizers
Pollution.
(2) sulphide precipitation:
Sulfurization-precipitation method is to convert insoluble or indissoluble sulfide precipitation for the heavy metal ion in waste water using vulcanizing agent, so
The method that surfactant makes sediment float is added afterwards.Sulphide precipitation metal removal rate is high, and the precipitating quantity of slag is less, precipitating
Metal in the dreg grade is high, convenient for the recycling in later period, the heavy metals such as arsenic, mercury, lead of removal more difficult for neutralization precipitation method from
Son, sulphide precipitation can remove.But vulcanizing agent price is more expensive, so that the processing cost of this method is very high, no
It is suitable for large-scale promotion.
(3) absorption method:
The method for removing dirty pollutant in water with solid absorbent, the referred to as absorption method of wastewater treatment.According to adsorbent type
Difference can be divided into material absorption method and biosorption process.Material absorption mainly utilizes the heavy metal in active carbon removal waste water
Ion, and biological adsorption is then to utilize heavy metal ion toxic in microorganism removal waste water.Absorption method because its handle material at
This is low, removal effect is good and is constantly subjected to the favor of people, but simultaneously, and there is also long processing period, facilities to take up an area face for absorption method
The disadvantages of product is big, primary construction high investment.
(4) membrane separation technique:
All separation processes of membrane separation technique are divided using the difference of the mixture each component property in certain environment
From.The principle of UF membrane is: penetrating film as separating medium using selectivity, is subject to certain thrust in two sides, stock blend is selectively
Through film, thereby achieving the purpose of separation and purification.Membrane separation technique has many advantages, such as low consumption, efficient, easy to operate, in heavy metal
Field of waste water treatment gradually draws attention.But since membrane module is expensive, fouling membrane and flux decline in use process, at present
The application study of membrane separation technique is concentrated mainly on experiment mechanism at present.
Currently, the generally existing disadvantages mentioned above of the method for barium ions in existing Beneficiation Wastewater.Therefore, it is necessary to get rid of
Existing processing technique thinking, hews out the new way of processing baric beneficiation wastewater, and then develops a kind of ore dressing of new type
