Abstract
The invention discloses a kind of processing method of industrial oil-containing heavy metal wastewater thereby, waste water inhales reactor, protopectin heavy metal Rotary adsorption pond, aeration nitrification tank, biological denitrificaion pond, sedimentation basin, water purifying tank by sump, coarse rack, microvesicle air supporting mineral oil adsorbent equipment, mineral oil catalysis again neutralizing successively.The creative V-type net-shaped drum that make use of equipped with pumpkin peel of the system is haptoreaction medium, when the waste water containing heavy metal is sufficiently mixed with pumpkin peel, the heavy metal ion in waste water is adsorbed by the suction-operated of the water-insoluble protopectin in pericarp membrane, part residue gradually forms sludge material in adsorption tank bottom precipitation.Meanwhile the pumpkin peel in V-type net-shaped drum can be replaced as a kind of low value consumptive material according to using Expenditure Levels.
Description
Technical field
The present invention relates to a kind of processing method of oil-containing heavy metal industrial effluent, the wastewater treatment neck belonged 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, its 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, harmfulness is reduced or is eliminated；
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 representational
Heavy metal significant etc. bio-toxicity, these heavy metals can not be decomposed in water environment, and the mankind drink rear toxicity amplification, with water
In other toxin combinations can generate the bigger organic compound of toxicity.
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 some dissolved matters in waste water
React, generate difficulty soluble salt and precipitate, this method is referred to 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 general principle of electrolysis, heavy metal ions in wastewater is set to occur respectively on anode and negative electrode
Redox reaction, make heavy metal accumulation, so that heavy metal in waste water is removed, and recyclable heavy metal.At electrolysis
Reason 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 that have using a kind of method of adsorbent absorption heavy metal in waste water, traditional adsorbent
The natural materials such as activated carbon, zeolite, clay mineral.The adsorption capacity of activated carbon is strong, and heavy metal clearance is high, 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 the last few years
By force, and earliest it is used for the mineral material of heavy metal containing wastewater treatment.
（4）Membrane separation process：Membrane separation process is to utilize a kind of special pellicle, in the presence of ambient pressure, is not changed
The chemical form of solution makes the method that solute and solvent are separated and concentrated.Phase does not occur during the course of the reaction for membrane separation technique
Change, separative efficiency is high, operates and easy to maintenance, and separation and concentration are carried out simultaneously, recyclable valuable heavy metal.Common
Membrane technology has micro-filtration, ultrafiltration, nanofiltration, counter-infiltration, 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 removes useless
Heavy metal in water, heavy metal ion in water outlet after concentration of heavy metal ion is handled far below chemical precipitation method in water outlet after purification
Concentration, pass through the solution after reclaiming, it is possible to achieve the recovery of heavy metal.Ion exchange resin performance heavy metal ion
Removal effect have considerable influence.
But heavy metal ion is frequently present in oily waste water now, because the presence of grease in water seriously hinders weight
The removal of metal, reduce 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.
The content of the invention
