Description
Technical field
The present invention relates to micro-electrolysis supported catalyst in a kind of sewage disposal, specifically refer to that a kind of copper base iron-carbon micro-electrolysis urgesAgent.
Background technology
The most important thing of current each enviromental protection enterprise to high concentration and highly difficult Industrial Wastewater Treatment. Also raw on marketProduced many similar products, wherein most products is all only to possess palliative processing, and its main cause is not choose and closeSuitable active component, thereby low for the selective absorption of target material, catalyst strength is inadequate, falling powder degree in sewage disposalLarger, and produce iron rust and coal ash to water generates secondary pollution.
Insider knows, particularly the sewage of the industry such as chemical fertilizer, agricultural chemicals, papermaking, wine brewing and printing and dyeing is very difficult to placeReason, all inorganic agents in the market, ubiquity pore volume and active on the low side, falling powder degree large, have secondary pollution to water,Service life short, the high deficiency of cost accounting. Although country attaches great importance to, the redoubling efforts to do it of enterprise, the micro-electricity of iron carbon of producingSeparate sewage-treating agent but still do not reach sewage disposal environmental requirement.
Summary of the invention
For above-mentioned deficiency, we,, through repeatedly studying and test of many times, have invented a kind of new catalyst, and it hasUnder certain high low temperature condition active good, pore volume is large, intensity is high, not powder falling, to water without secondary stain, long service life, costLow copper base iron-carbon micro-electrolysis catalyst. On the basis of catalyst research and development and production technology, we use the method for increase, shapeBecome copper base iron carbon supported catalyst, make it in the process of desulfurization, dechlorination, dephosphorization, remove efficiently the COD in all kinds of sewage, de-Except colourity, improve biodegradability.
A kind of copper base iron-carbon micro-electrolysis catalyst of the present invention's development is by industrial oxidation copper (CuO), di-iron trioxide（Fe2O3), the composition such as brown coal, structural promoter, high stick. Active component is CuO, Fe2O3, brown coal.
In the present invention, be one or both shapes by industrial oxidation copper, copper chloride, copper carbonate and waste copper slag adding of copperFormula adds, but adds best with industrial oxidation copper and waste copper slag form.
Preparation component of the present invention component by weight: industrial cupric oxide 10-20, di-iron trioxide 30-40, brown coal 35-42,Structural promoter 5-40, high stick 5-20.
Structural promoter in the present invention refers to one or both of calcium aluminoferrite cement, natural plant gum, kaolin and mixture.
The weight content CaO of the chemical analysis in finished product of the present invention accounts for the 0.6-6.0% that product is heavy, and Fe2O3 accounts for 25-36%.
The present invention, in the time selecting copper ashes, copper chloride, copper carbonate to do raw material, determines weight group with the CaO content in raw materialThe addition of part.
High stick of the present invention refers to that kaolin, attapulgite, Yang earthenware soil, pore creating material are a kind of or gets two kinds and group by weightPart 5-20 adds.
Pore creating material of the present invention refers to one or both of ammonium chloride, ammonium sulfate, carbonic hydroammonium.
Processing technology of the present invention is: after above-mentioned raw materials is mixed by its composition by weight, vacuum kneading is closed routinelyMethod is again with just base of mould compacting, and the shape of first base is determined by user, is generally irregular oval flat graininess copper base iron carbonJust base of micro-electrolytic catalyst, then through 150 DEG C dry after, then at 1100-1300 DEG C of roasting in kilns, cooling after its iron carbon of copperMicro-electrolytic catalyst.
Crush strength >=the 150N/cm of finished catalyst of the present invention2, specific area is > 425m2/ g, bulk density 820-860kg/m3, mesoporous pore volume 58%.
This catalyst for edible running water, life civil water, livestock drinking water, natural stagnant water, sewage, industrial wastewater,Agricultural chemicals, chemical engineering sewage, papermaking, printing and dyeing dull colour water, smelting iron and steel contain the processing of heavy metal-containing polluted water, can efficiently remove all kinds of sewageIn COD value.
The serviceability temperature of catalyst can be within the scope of-60 DEG C～700 DEG C, and working pressure is 0.1-9.0MPa.
Invention effect:
The multinomial technical indicator of catalyst of the present invention has improved 35-than iron-carbon micro-electrolysis inorganic agent effect in the marketMore than 50%. Test as follows:
This catalyst carries out contrast test with domestic like product:
Experimental condition: catalyst amount 0.5kg
Indicator reaction: normal temperature, normal pressure
COD removal effect: 76%
Hole branch (mesoporous): 58%
Hole branch (grand hole): 6.3%
Hole branch (micropore): 75%
The removal COD effect of 4 kinds of different catalysts has been selected in test.
Result is as shown in table 1:
| 4 kinds of different microelectrolysis processing agent | A1 | A2 | A3 | A4 |
| COD removal effect | 27% | 31% | 29% | 30.5% |
| Hole branch (mesoporous) | 45% | 40% | 44% | 46% |
| Hole branch (grand hole) | 2.6% | 2.5% | 2.6% | 2.9% |
| Hole branch (micropore) | 47% | 45.5% | 46% | 48.2% |
Environmental-protecting performance and the de-absorption property of 4 kinds of filler sewage-treating agents also investigated in test. By its 4 kinds of inorganic agents respectivelyBubble, in the plastic cup of filling running water, is watched glass water in 24 hours more muddy, has one deck floating thing to belong to the oil of ature of coal aboveFat and thin ash. Floating thing precipitation after 3 days, obviously observes inorganic agent appearance and wraps up in full muddy material, shakes brimmer dirt with hand oneTurbid shape. After 15 days, in higher than normal temperature 20 degree situations, inorganic agent starts the surface iron carbonizable substance that comes off, and produces water in the cup and become ironThe yellow color of becoming rusty. Above four kinds of basic conditions are the same, have a strong impact on the de-adsorption effect of inorganic agent and life-span.
Copper base iron C catalyst environmental-protecting performance of the present invention and de-absorption property, done equally test and investigated, and within 24 hours, examinesSee the water in plastic cup, substantially there is no floating thing, within 5 days, do not find afterwards sediment, 15 days post-treatment agents, without surperficial cast, remove certainlyThe microprecipitation beyond the region of objective existence producing in water, in cup water, without any rust, water quality is very limpid. Not only prevent processing two of waterInferior pollution, has more embodied the best de-adsorption effect of inorganic agent and service life.
The operational characteristic of raw catelyst:
