Description

A kind of processing system of the heavy metal industrial effluent of oil-containing
Technical field
The present invention relates to a kind of processing systems of oil-containing heavy metal industrial effluent, belong to the wastewater treatment neck in environmental protection Domain.
Background technology
Heavy metal pollution refers to as the environmental pollution and ecological disruption caused by heavy metal and its compound, the extent of injury Depending on heavy metal concentration and chemical form present in environment, food and organism.Heavy metal pollution is mainly manifested in water In pollution, some is in air and solid waste.Heavy metal pollution is different from the pollution of other organic compounds, much Organic compound can be purified by the physics of nature in itself, chemistry or biological effect, reduce or eliminate harmfulness; And heavy metal has enriching, it is difficult to degrade in the environment.
In terms of environmental pollution, it is mercury, cadmium, lead and " metalloid " --- arsenic that heavy metal pollution is most representative Etc. the significant heavy metal of bio-toxicities, these heavy metals cannot be decomposed in water environment, the mankind drink the amplification of rear toxicity, with water In the combination of other toxin can generate the organic compound of toxicity bigger.
At present, existing industrial wastewater heavy metal processing method includes:Chemical precipitation method, electrolysis, absorption method, UF membrane Method, ion-exchange etc..
(1)Chemical precipitation method:Certain chemical substance is added in industrial wastewater, makes itself and dissolved matters certain in waste water It reacts, generates difficulty soluble salt and precipitate, this method is known as chemical precipitation method.Traditional chemical precipitation method includes neutralizing The precipitation method, sulphide precipitation and barium salt precipitation method etc..
(2)Electrolysis:Using the basic principle of electrolysis, heavy metal ions in wastewater is made to occur respectively on anode and cathode Redox reaction makes heavy metal accumulation, so as to which heavy metal in waste water be enable to remove, and recyclable heavy metal.At electrolysis Managing heavy metal wastewater thereby has the features such as reliable, heavy metal removing rate is high, recoverable.But due to heavy metal concentration it is low when Power consumption is big, cost of investment is high, and electrolysis is only suitable for handling high-concentration heavy metal waste water.
(3)Absorption method:Absorption method is using a kind of method of adsorbent absorption heavy metal in waste water, and traditional adsorbent has The natural materials such as activated carbon, zeolite, clay mineral.The adsorption capacity of activated carbon is strong, and to heavy metal removing rate height, but price is held high Expensive, service life is short.Found that mineral material had very strong adsorption capacity, wherein natural zeolite adsorption capacity most in recent years It is used for the mineral material of heavy metal containing wastewater treatment by force and earliest.
(4)Membrane separation process:Membrane separation process is using a kind of special semi-permeable membrane, under the action of ambient pressure, is not changed The chemical form of solution makes the method that solute and solvent are detached and concentrated.Phase does not occur during the reaction for membrane separation technique Variation, separative efficiency is high, operates and easy to maintain, and separation and concentration are carried out at the same time, recyclable valuable heavy metal.Common Membrane technology has micro-filtration, ultrafiltration, nanofiltration, reverse osmosis, electrodialysis, liquid film etc..
(5)Ion-exchange:Ion-exchange processing heavy metal wastewater thereby be using on ion exchange resin it is commutative from With heavy metal ion exchange reaction occurs for son, so as to remove the method for heavy metal ions in wastewater.Ion exchange technique removal is useless Heavy metal in water, concentration of heavy metal ion is far below heavy metal ion in being discharged after chemical precipitation method processing in being discharged after purification Concentration, by the solution after reclaiming, can realize the recycling of heavy metal.Ion exchange resin performance is to heavy metal ion Removal effect have larger impact.
But heavy metal ion is frequently present in oily waste water now, since the presence of grease in water seriously hinders weight The removal of metal reduces the treatment effect of heavy metal ion.Therefore, it is necessary to break away from existing treatment technology thinking, open up The new way of source science and engineering industry heavy metals, and then develop a kind of industrial wastewater heavy metal treatment technology of new type.
