Abstract
The invention provides a microcell spontaneous sewage treatment agent, which comprises gas ash, recycled iron powder and ordinary portland cement in a mass ratio of 50-56:28-34:16, wherein the gas ash is furnace dust produced in the blast-furnace ironmaking and dedusting process; and the recycled iron powder is crushed waste iron slag produced in the blast-furnace ironmaking and dedusting process. The preparation method comprises the following steps of: uniformly mixing the gas ash, the recycled iron powder and the ordinary portland cement according to the mass ratio of 50-56:28-34:16; adding water according to a mass ratio of the water to the ordinary portland cement of 1:1 and uniformly stirring to prepare raw materials; and extruding the raw materials into raw material pellets and curing for 3 to 7 days in a wet area. The preparation technology is simple, industrial wastes and plant straws are adopted to protect environment and save energy, and the prepared sewage treatment agent breaks hardly degradable pollutants in sewage by using electric energy spontaneously produced by a microcell so as to effectively reduce the CODcr and chromaticity of the sewage.
Description
Technical field
The present invention relates to a kind of microbattery self start type sewage-treating agent and preparation method thereof, belong to technical field of sewage.
Background technology
Along with the intensification of industrialization degree, the industrial sewage quantity discharged presents the trend that rises gradually, and trade effluent also more and more is difficult to degraded and handles.With the dyeing waste water is example: dyeing waste water is one of at present main harmful, difficult trade effluent of China, mainly comprises the dyestuff organism and the dyeing and printing auxiliary that have chromophoric group.Be characterized in that wastewater flow rate is big, water quality is complicated, organic concentration is high, that recalcitrant substance reaches colourity more is dark etc.Wherein serious with the pollution of dyestuff especially, even its remaining dye component concentration is very low, also can cause the water body transmittance to reduce, thus the destruction that causes ecotope.In recent years, because the development of textile printing and dyeing industry and the raising of dyeing and finishing technique have increased the organism of bio-refractories such as a large amount of PVA dyestuffs, New-type adjuvant, thereby have strengthened the intractability of dyeing waste water in the dyeing waste water.
Not only floor space is big, investment is high for existing sewage water treatment method, working cost is high, and decarburization, denitrogenation and decolorizing effect are all not satisfactory.CN1289408C discloses a kind of " the paper industry sewage-treating agent is produced treatment process ", is to adopt by kaolin ore, and barite, talcum powder, hydrochloric acid, calcium sulfite are raw material, and the preparation process complexity easily causes secondary pollution.
Summary of the invention
The present invention is directed to the deficiency that existing sewage disposal technology exists, a kind of microbattery self start type sewage-treating agent simple, good sewage processing effect for preparing is provided, this treatment agent utilizes the electric energy of the spontaneous generation of microbattery to break the pollutent of difficult degradation in the sewage, thereby effectively reduce COD of sewage cr, colourity etc., finally make the sewage qualified discharge.A kind of preparation method of this sewage-treating agent is provided simultaneously.
Microbattery self start type sewage-treating agent of the present invention comprises gas ash, reclaims iron powder and ordinary Portland cement, and the mass ratio of gas ash, recovery iron powder and ordinary Portland cement is 50～56: 28～34: 16; Wherein gas ash is the stove dirt that produces in the blast furnace ironmaking dust removal process, and reclaiming iron powder is the scrap iron slag through pulverizing that produces in the blast furnace ironmaking dust removal process.
The preparation method of above-mentioned granular self start type microbattery sewage-treating agent may further comprise the steps:
The stove dirt that produces in the blast furnace ironmaking dust removal process is sieved below 100 orders (1) that (mean particle size≤0.154mm) is made gas ash; Scrap iron slag in the blast furnace ironmaking is pulverized and sieved and make the recovery iron powder below 100 orders through ball mill;
(2) with gas ash, reclaim iron powder and ordinary Portland cement according to mass ratio 50～56: 28～34: 16 mixed is even, stir according to water and 1: 1 ratio of ordinary Portland cement mass ratio interpolation water subsequently and make raw material, raw material are squeezed into raw material ball (particle diameter can be controlled as required) in the extruding type nodulizer, raw material ball are positioned over the maintenance of moistening place got final product in 3 days～7 days.
The present invention relies on the energy that galvanic cell discharged of Fe-C composition that the material (as dye molecule, macromole organic molecule, virocyte etc.) of difficult degradation in the sewage is carried out electrolysis, thereby plays the effect of purifying waste water.
Preparation technology of the present invention is simple, and adopting industrial waste and straw is raw material, environmental protection and energy saving, and the sewage-treating agent of preparation utilizes the electric energy of the spontaneous generation of microbattery to break the pollutent of difficult degradation in the sewage, thereby effectively reduces the CODcr and the colourity of sewage.
