Abstract
A kind of processing method for the industrial wastewater heavy metal pollution being combined the invention discloses chemical leaching and biological respinse, waste water are handled by water leg, coarse rack, primary sedimentation basin, pH value regulating reservoir, heavy metal ion chelatropic reaction tower, whizzer, secondary sedimentation tank, water purifying tank successively.The system creativeness make use of a kind of spherical carrier for being attached with cysteine bovine serum albumin(BSA) as surface haptoreaction medium, when the waste water containing heavy metal is contacted with refining the state of water smoke with its surface, and produce synergy with the component of chemical leaching liquid, make the heavy metal ion in waste water that chelatropic reaction occur with cysteine (Cys) bovine serum albumin(BSA) by the inducing action of Analyses of High Affinity Binding Peptides, with copper, zinc, lead, chromium, cadmium, platinum, silver, golden contents of many kinds of heavy metal ion produces chelation, generate metal complex, the complex compound is not soluble in water, removed by centrifuging operation.Its removal efficiency of heavy metals is up to 99.2%.
Description
Technical field
A kind of processing method for the heavy metal pollution industrial wastewater being combined the present invention relates to chemical leaching and biological respinse,
The field of waste water treatment belonged in environmental protection.
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.
Because above-mentioned traditional treatment method has the shortcomings of cost height, technical sophistication, unstable treatment effect, therefore, have
Necessity breaks away from existing treatment technology thinking, hews out the new way of processing industrial wastewater heavy metal, and then develops a kind of brand-new
The industrial wastewater heavy metal treatment technology of form.
The content of the invention
To solve the deficiencies in the prior art, it is combined the invention provides a kind of chemical leaching and biological respinse
The processing method of heavy metal pollution industrial wastewater, the industrial wastewater containing heavy metal enter water leg, water leg by waste line
Outlet coarse rack is connected by waste line, the outlet of coarse rack passes through waste line and connects primary sedimentation basin, primary sedimentation
The outlet in pond connects pH value regulating reservoir by waste line, and the outlet of pH value regulating reservoir connects heavy metal ion by waste line
Chelatropic reaction tower, the outlet of heavy metal ion chelatropic reaction tower connect whizzer by waste line, centrifuge operation
The heavy metal sewage sludge outward transport processing of middle discharge, the outlet of whizzer connect connecting secondary sedimentation basin by waste line, and two
The outlet of secondary sedimentation basin connects water purifying tank by waste line, and the outlet of water purifying tank passes through waste line by purifying after processing
Arranged outside water；Wherein, heavy metal ion chelatropic reaction top of tower is equipped with chemical leaching liquid liquid flowing valve, and is connected with shunt catheter,
Current are divided into five branch roads by shunt catheter, and its end is connected with five spray heads, 11 layers of protein have been filled in the middle part of reaction tower
Carrier ball, is attached with the mixture of cysteine and bovine serum albumin(BSA) on protein carrier ball, reaction tower upper right quarter be equipped with into
Penstock, reaction tower bottom are equipped with flowing water Valve；Industrial wastewater after pH value regulation processing is chelated by heavy metal ion
The penstock that enters of reaction tower upper right quarter enters inside reaction tower, by being sprayed onto protein after atomizer with the state of water mists
On carrier ball, while chemical leaching liquid is also sprayed onto on protein carrier ball with the state of water droplet, waste water and chemical leaching liquid with
The cysteine and bovine serum albumin(BSA) adhered in protein carrier ball surface is in contact, and is made by the induction of Analyses of High Affinity Binding Peptides
Chelatropic reaction, generation occurs with the heavy metal ion made in waste water and cysteine, bovine serum albumin(BSA) and chemical leaching liquid
