Description
Technical field
The present invention relates to technical field of waste water processing, be specifically related to a kind of filler that is used for wastewater treatment and preparation method thereof.
Background technology
The seventies in 20th century, Soviet Union scientific research personnel at first is mixed into the processing that micro-electrolysis stuffing is applied to dyeing waste water to iron filings and coke.This technology is introduced China in the eighties in last century; Over nearly 30 years; Because this technology has characteristics such as technology is simple, processing cost is low, good decolorizing effect; Be applied to printing and dyeing, in the wastewater treatment in field such as chemical industry, plating, pharmacy, oil field, especially the processing for high salinity, high COD, high-colour intensity wastewater has remarkable advantages than other technologies.
But there are problems in conventional iron charcoal micro electrolysis tech: for traditional iron charcoal micro electrolysis tech, the iron carbon filler surface that is in operation can form passive film, the carrying out of influence reaction; Generally after 1-3 month; Processing efficiency sharply descends, and the life-span of filler is very short, has limited The Application of Technology and popularization.And traditional iron-carbon filling material is prone to caking, phenomenon such as channel occurs, reduced effective contact area of filler and waste water, also is the major reason of conventional art processing efficiency low (the about 15-30% of COD clearance).Traditional iron-carbon filling material can produce a large amount of discarded iron mud owing to can not regenerate, and influences surrounding enviroment, has also influenced technological popularization.It is bigger to the most important thing is that traditional iron-carbon micro-electrolysis is influenced by applied environment, and general requirement is carried out the acid adjustment processing, and not obvious to considerable murder by poisoning organism treatment effect.
General method of wastewater treatment comprises Fe-C Micro Electrolysis Method now, and its principle of handling waste water all is to make pollutants in waste water be oxidized to nontoxic product.And comprise a large amount of nitryl aromatic hydro carbons, azo class, halogenated hydrocarbon compound and poisonous and harmful heavy metallic usually in the waste water of dyeing waste water, pharmacy waste water, wastewater from chemical industry, agricultural chemicals waste water and so on difficult degradation; These materials are rich in two keys, the two keys of carbon, hale electron group, azo bond, phenyl ring class equimolecular structure; Be difficult for oxidized; But be reduced easily, and the product after the reduction weakens the biodegradable raising greatly to toxicity and the inhibition of mikrobe.Can pass through reduction dechlorination like hydrochloric ether, oil of mirbane is the less hydroxyanilines of toxicity etc. through the reduction degradable.
If pollutent can be handled through reduction technique and make it that take place preliminary the decomposition in the waste water of above-mentioned difficult degradation, the biodegradability of waste water can increase substantially, and helps promoting the efficient that wastewater biochemical is handled.Up to now, the research of this respect also relatively lacks, and technology is also immature.
Summary of the invention
For overcome traditional iron-carbon micro-electrolysis filler life-span short, be prone to caking, processing efficiency is low and easy to be affected by environment and produce the more shortcoming of dead meal, the invention provides a kind of wastewater treatment filler that is applied to wastewater treatment and preparation method thereof.
Wastewater treatment filler provided by the invention with the nano level metal of multiple low potential as the anode reductive agent, with noble potential nano level metal and carbon as negative electrode.The ultimate principle of said wastewater treatment filler is the original battery electrochemistry reaction that anode and negative electrode constitute; The noble potential metallic cathode also has electrocatalysis except that enlarging potential difference, and for reducing reaction interface is provided; And the microbattery system of a plurality of short circuits of formation between anodic alloy and the trace impurity, but the accelerating anode oxidation, other combines the complexing of anode ionic, electron transport, physisorption.Make said wastewater treatment fillers have strong reducing property, the principal pollutant in the waste water such as nitryl aromatic hydro carbons, azo class, halogenated hydrocarbon compound and poisonous and harmful heavy metallic are all had deoxidization, degradation effect preferably.
The objective of the invention is to realize through following technical scheme: a kind of wastewater treatment filler, it is characterized in that its raw material and weight percent thereof do,
Each raw material of above-mentioned wastewater treatment filler all can be buied from market, and purity requirement is more than 98wt%.
The present invention also provides a kind of preparation method of wastewater treatment filler, and step is following:
(1) with the powder of each component raw material pulverize separately, ball milling to 10 nanometer-100 micron, uniform mixing is by weight percentage processed particulate mixtures through tablets press at last then;
(2) then with particulate mixtures through 500 ℃ of-1000 ℃ of sintering of temperature or through being cold-pressed into particulate state.Particle shape is spherical or cylindric, square shape, or in various pending water devices, is cold-pressed into the respective shapes that needs.
The method of use of said wastewater treatment fillers is: granular filler is dropped into (material-water ratio is 1: 3-10) in the wastewater treatment equipment; Said wastewater treatment equipment can be liquid bed, aeration fluidized bed, fixed bed or other present technique fields treatment unit commonly used, the method for operation in operation of pressing this wastewater treatment equipment again.
The present invention with COD (abbreviating COD as) as weighing what index of organic pollutant content in the water.COD is big more, explains that water body receives organic pollution serious more.The present invention uses the conventional COD survey meter that uses in present technique field to measure the COD value of waste water.
The activation recovering device that this filler can adopt U.S. sunlight Pharma Inc. to produce carries out active regeneration.
The method of use of wastewater treatment fillers provided by the invention both can be used as independent treatment process; Can be used as the pretreatment process of biological process again; As as pre-treatment; Except that the biochemical that can make waste water is improved, also can directly be coupled with follow-up aerobe method, iron ion more than needed helps the removal of phosphorus and improves the settling property of active sludge or the extension film ability of biomembrance process.This method can reach the effect of chemical precipitation dephosphorization, can also remove heavy metal through reduction.
Compared with prior art, wastewater treatment fillers provided by the invention has following characteristics:
(1) speed of reaction is fast, and the wastewater treatment time only needs several minutes to tens of minutes; Treatment capacity is big, and material-water ratio is 1: 3-10;
(2) have good coagulation effect, the COD clearance is high, and the COD clearance is generally at 50-70%; And the removal to colourity is better;
(3) life-span long, cost is low, generally is no more than 0.50 yuan/ton;
(4) effect organic pollution materials scope is wide, as: the hardly degraded organic substance matter that contains even fluorine, the two keys of carbon, nitro, halogeno-group structure; Be suitable for the PH wide ranges, acid, neutral, alkaline condition all has good effect;
(5) operational management is convenient, not passivation, channel not, no waste.
With each item performance of wastewater treatment filler provided by the invention and existing iron-carbon micro-electrolysis filler, the result is as shown in table 1:
Two kinds of carrier performances of table 1 relatively
