Abstract
The invention discloses a micro-electrolyzer production process for waste water treatment. The micro-electrolyzer production process is characterized in that the production process comprises the following steps: mixing iron ore powder or iron oxide scale, graphite powder, humic acid and water evenly in a certain proportion; using a ball forming mill to make the mixture into 3 to 8mm ball lump Q; crushing and mixing evenly anthracite and quick lime in a weight ratio of 8:1 to form a reducer H; mixing Q and H according to a weight ratio of 9:4 and adding the mixture into a refractory container; and adding the refractory container into a reducing furnace after sealing; carrying out reduction on the mixture for 36 hours at a temperature of between 1,050 and 1,150 DEG C; cooling down and taking out the mixture, and removing the reducer H to form a granular reduction product which is the micro-electrolyzer. The process has the advantages of simple process flow, low investment cost, convenient operation, low running cost and stable processing effects.
Description
Technical field
The present invention relates to a kind of fine electrolyser production technique that is used for wastewater treatment.This fine electrolyser is used under the normal temperature and pressure the little electrolysis treatment to various waste water, and especially at the organic concentration height, the processing of the waste water of biochemical difference can reduce the colourity and the COD of waste water significantly, improves the biodegradability of waste water; The processing and the treating water reuse project of all types of industries waste water such as this fine electrolyser is widely used in printing and dyeing, chemical industry, plating, pulping and paper-making, pharmacy, scouring of wool, agricultural chemicals, alcohol.
Background technology
At present, a large amount of high-concentration and high-chromaticities that industries such as chemical industry, pharmacy, papermaking, printing and dyeing are discharged, the waste water of difficult degradation is at present domestic generally handles with biological process, and cost height and effect are relatively poor, and some almost can not be degraded; Domesticly with the iron filings micro-electrolysis method high-concentration waste water is handled, obtained good effect on certain limit, but iron filings are owing to be mach waste material that specific surface area is little, processing power is lower, and the easy passivation of long-time running is hardened and lost treatment effect.
Summary of the invention
Purpose of the present invention is that a kind of fine electrolyser is provided, the fine electrolyser that the method that the present invention adopts direct reduction to add carburizing is produced has very high specific surface area (1.2 meters squared per gram), stronger in aqueous solution middle-jiao yang, function of the spleen and stomach polaron activity, the anode and cathode proportioning is suitable, little electrolysis effectiveness is good, treatment time to water is short, and the long-time running effect stability can not harden.
For reaching above purpose, production technique of the present invention is, with A: B: C: water was by weight 15: 1: 1: 1 mixed is evenly made the pelletizing Q of 3-8mm with nodulizer, described A is powdered iron ore or iron scale, iron content is greater than 68%-69%, and fineness is the 100-300 order, and described B is a Graphite Powder 99, fineness is the 100-300 order, and described C is a humic acids; D: E is mixed formation reductive agent H by weight pulverizing in 8: 1, and described D is a hard coal, and fugitive constituent 12%-18%, fixed carbon are greater than 70%, and described E is a unslaked lime, and calcium oxide is greater than 50%; Q is mixed in the reduction furnace of packing into after the refractory container of packing into also seals by weight 9: 4 with H, reduction is 36 hours under 1050 ℃-1150 ℃ temperature, cooling is afterwards taken out, and reductive agent H is removed, and the particulate state reduzate of formation is the fine electrolyser of production required for the present invention.
By the fine electrolyser that above technology is produced, the present invention possesses following advantage:
1, speed of reaction is fast, and commonly industrial wastewater only needs 30-60 minute;
2, 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;
3, technical process is simple, investment cost is few, easy to operate, running cost is low, treatment effect is stable.
4, long service life, convenient operating maintenance only consumes a spot of micro-electrolysis reaction agent in the treating processes, and fine electrolyser only needs regularly to add and need not to change;
5, have good coagulation effect, need not to add again coagulating agent such as molysite, COD clearance height;
6, can reach the effect of chemical precipitation dephosphorization, can also be by the reduction removing heavy metals;
7, specific surface area is big, provides bigger current density to wastewater treatment, and little electrolysis effectiveness is good, and long-time running is effectively stable.
Embodiment
With A: B: C: water was by weight 15: 1: 1: 1 mixed is evenly made the pelletizing Q of 3-8mm with nodulizer, described A is powdered iron ore or iron scale, and iron content is greater than 68%-69%, fineness is the 100-300 order, described B is a Graphite Powder 99, and fineness is the 100-300 order, and described C is a humic acids; D: E is mixed formation reductive agent H by weight pulverizing in 8: 1, and described D is a hard coal, and fugitive constituent 12%-18%, fixed carbon are greater than 70%, and described E is a unslaked lime, and calcium oxide is greater than 50%; Q is mixed in the reduction furnace of packing into after the refractory container of packing into also seals by weight 9: 4 with H, reduction is 36 hours under 1050 ℃-1150 ℃ temperature, cooling is afterwards taken out, and reductive agent H is removed, and the particulate state reduzate of formation is the fine electrolyser of production required for the present invention.
The present invention is to the wastewater treatment principle: when thing of the present invention was in the waste water, it produced high low potential difference waste water is carried out electrolysis treatment under cold situation, to reach the purpose of degradable organic pollutant.The nascent state that system produces in treating processes [H], Fe2+ etc. can also with the many component generation redox reactions in the waste water, such as chromophoric group that can destroy the coloring matter in the colorful wastewater or auxochrome group, even chain rupture, reach the effect of degradation and decolorization; The Fe2+ that generates further is oxidized to Fe3+, their hydrate has stronger absorption-flocculation activity, particularly after adding the adjusting PH with base value, generate ferrous hydroxide and ferric hydroxide colloid flocculation agent, their adsorptive power is higher than the ferric hydroxide colloid that general medicament hydrolysis obtains far away, dispersive molecule, metallics and organic macromolecule in a large amount of planar water of energy. its principle of work is handled waste water based on the acting in conjunction of electrochemistry, oxidation-reduction, physical adsorption and flocculation sediment.
