Description
Technical field
The present invention relates to a kind of method updating adsorbing material process lead waste water voluntarily, belong to wastewater processing technology neck
Territory.
Background technology
Montmorillonite is the layer mineral being made up of the hydrous alumino silicates that granule is superfine, and title derives from the product first found
Ground.Montmorillonite subtribe belongs to one of smectite race mineral, is important clay mineral, the most block or earthy.Molecular formula
(Al, Mg)2[Si4O10](OH)2·nH2O, centre is alumina octahedral, the three-layer tablet shape knot formed by silicon-oxy tetrahedron up and down
The clay mineral of structure, and some exchange cations aqueous at crystal structure interlayer, there is higher ion exchange capacity, have higher
Imbibition ability.Montmorillonite Crystal belongs to monoclinic aqueous layer silicate mineral.
Lead is the element that distributed in nature is the widest, is also one of normal element used in industry, many with sulfur in nature
Solvate forms exists, and is metallic state the most on a small quantity, and often coexists with the element such as zinc, copper.Lead and compound thereof are that one can not drop
The environmental contaminants solved, can flow into environment in a large number by waste water,waste gas and industrial residue, direct with air by food chain, soil, water
Or indirectly enter human body, damage hemopoietic system, cause anemia, nervous system peripheral nerve scorching, also can flow into brain group with blood
Knit, infringement cerebellum and brain cortex cell, disturb metabolic activity, cause brain injury, and Toxicity of Lead is lasting, long half time
Reaching 10 years, be difficult to be discharged by human body, health all can be had a negative impact by the lead contamination of any degree.Total lead in waste water
For first kind pollutant, lead waste water such as needs discharge, and total lead must reach the highest permission of first kind pollutant at workshop floss hole
Emission concentration standard.
At present, heavy metal in waste water lead ion, industrial general employing chemical precipitation method, ion exchange, electrolysis are processed
Method.Chemical precipitation method equipment is simple and convenient to operate, high treating effect, at present, to high concentration, the place of the lead waste water of big flow
Ought to relatively universal, but costly, treating capacity is little, poor selectivity, sludge quantity big, mud is the most disposable, easily cause secondary pollution.
Ion exchange has that floor space is little, convenient management, lead ion removal efficiency high, and processes and proper make regenerated liquid as money
Source is reclaimed, and environment will not cause secondary pollution, but one-time investment is big, and operating cost is high, resin vulnerable to pollution or oxidation
Losing efficacy, frequently, regeneration issues there is also certain difficulty in regeneration.Electrolysis technical maturity, has clearance high, dirty without secondary
Dye, the heavy metal recoverable precipitated, relatively strong to waste water quality change adaptability, the response time is short, but processes a large amount of useless
During water, energy consumption is big, and electrode metal consumption is big, is not suitable for high-concentration waste water.
Summary of the invention
The technical problem that present invention mainly solves: process lead waste water for the most traditional ion exchange and disposably throw
Money is big, and operating cost is high, processes material vulnerable to pollution or oxidation deactivation, regenerates frequently, and regeneration issues there is also certain difficulty
Problem, it is provided that a kind of voluntarily update adsorbing material process lead waste water method.The method is to have the exchange of relatively macroion
The montmorillonite of capacity is raw material, first through " ice splits effect " and the composite modified interlamellar spacing widening montmorillonite of cation quaternary ammonium salt, then
Humic acid substance in the humus prepared with fermentation voluntarily is modified to it, increases the complexing power between montmorillonite and lead ion
Adsorb the lead ion in waste water, and adsorb saturated after can aging adsorbing material top layer, under waste water percussion, adsorb top layer
Can come off layer by layer, expose internal new adsorption layer, continue lead ion is adsorbed, reach the purpose updated voluntarily, it is not necessary to
Regeneration, simplifies process step, saves operating cost, has broad application prospects.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
(1) by weight mark meter weigh 20～25 parts of wheat stalks, 30～55 parts of withered leaveves, 15～20 parts of chicken manures, 15～18
Loading in fermentation tank after part pig manure, 8～10 parts of bed-silts and 40～50 parts of methane liquid mix homogeneously, hermetically sealed can mouth is 30～35
At DEG C, heat-preservation fermentation rots 3～5 weeks, obtains putrid fermentation thing, standby；
(2) dodecyl dimethyl benzyl ammonium chloride that 800～900g montmorillonites immersion 8～10L mass concentrations are 10% is weighed molten
In liquid, after sonic oscillation dipping 2～3h, be removed and placed in refrigerator freeze overnight at-20～-15 DEG C, to be frozen after montmorillonite
Recover room temperature, obtain inorganic modified montmorillonite；
(3) with gauze by above-mentioned inorganic modified after montmorillonite wrap after put in standby putrid fermentation thing, continue 30
～modified 10～12 days of fermentation in the greenhouse of 35 DEG C, take out the inorganic modified montmorillonite of gauze parcel, and use deionized water rinsing
20～30min post-dryings are updated adsorbing material voluntarily；
(3) the above-mentioned adsorbing material of renewal voluntarily being laid on area is 20m2, altogether in the adsorption tower of 3～5 layers, wherein every layer of paving
If thickness is 30～50cm, the space height between every layer is 80～100cm, by lead waste water from absorption tower top after having laid
Portion is passed through, and flows out in water outlet at the bottom of tower, and wherein water inlet flow speed control is 10～15m3/ h, waste water the time of staying of every layer be 20～
30min；
(4) under the percussion of lead waste water, voluntarily regenerative adsorption material surface the adsorbance of lead ion is reached saturated after,
Saturated aging adsorbing material surface can come off layer by layer, exposes internal new adsorption layer, continues to adsorb lead ion, reaches
To the purpose updated voluntarily, the waste water after being disposed gets final product qualified discharge.
The principle of the present invention is: the present invention with there is relatively high ion exchange volume montmorillonite as raw material, first through " ice splits work
With " widen the interlamellar spacing of montmorillonite, increase ion exchange capacity, absorption can be swapped with lead ion in water, then with voluntarily
Humic acid substance in the humus of fermentation preparation is modified to it, and the complexing power increased between montmorillonite and lead ion adsorbs
Lead ion in waste water, and adsorb saturated after can aging adsorbing material top layer, under waste water percussion, absorption top layer can be layer by layer
Come off, expose internal new adsorption layer, continue lead ion is adsorbed, reach the purpose updated voluntarily, it is not necessary to regeneration, letter
Change process step, save operating cost.
The invention has the beneficial effects as follows:
(1) method that the present invention processes lead waste water, processing equipment is simple, and floor space is little, and operating cost is low, processes step letter
Just；
(2) method that the present invention processes lead waste water, adsorbing material, without regeneration, can update, voluntarily after testing, through the present invention
The lead waste water processed, plumbum ion concentration be have decreased to below 0.6mg/L, lead ion clearance by 500mg/L when intaking
Reach more than 99.88%.
