Problems solved by technology

[0004] In order to solve the above problems, the present invention designs a multi-component catalytic iron-carbon micro-electrolytic filler and its preparation method. Under the multi-component catalysis of two kinds of non-ferrous metal powders and inorganic catalysts, a trinity micro-electrolytic filler of iron-non-ferrous metal-activated carbon is formed. The battery group increases the potential difference of the iron-carbon micro-battery, the reaction speed is faster, and the reaction ratio is controllable, the contact ratio between the pollutant and the micro-battery is increased by three times, and the efficiency of sewage oxidation treatment is increased by 2-3 times. There is no direct contact between them, so there is no hardening phenomenon, no need to replace or regenerate the filler, and the preparation method is simple

Abstract

The invention discloses multielement catalysis iron-carbon micro-electrolysis filler and a preparation method thereof. The multielement catalysis iron-carbon micro-electrolysis filler mainly comprises 55-75 parts of iron powder, 10-30 parts of active carbon powder, 5-20 parts of nonferrous metal powder catalyst A, 5-10 parts of nonferrous metal powder catalyst B and 5-10 parts of inorganic catalyst C. The preparation method comprises the steps of weighing, extruding, primary moulding and high-temperature sintering. The invention has the advantages that the multielement catalysis iron-carbon micro-electrolysis filler disclosed by the invention overcomes the defects that the traditional scrap iron is hardened easily and generated sludge is tripled or quadrupled after reaction because reaction speed cannot be controlled when micro cell reactions are excessive, iron-carbon micro cell potential difference is enlarged, reaction speed is higher, reaction ratio can be controlled, contact ratio of pollutant to a micro cell is tripled, sewage oxidation treatment efficiency is doubled or tripled, no hardening is caused as iron atoms are not in direct contact, and the filler does not need to be replaced or regenerated.

Description

technical field [0001] The invention relates to an iron-carbon micro-electrolysis filler, in particular to a multi-element catalytic iron-carbon micro-electrolysis filler and a preparation method thereof, belonging to the field of iron-carbon micro-electrolysis fillers. Background technique [0002] Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater, also known as internal electrolysis. It uses the micro-electrolytic material filled in the wastewater to generate a 1.2V potential difference to electrolyze the wastewater to achieve the purpose of degrading organic pollutants without electricity. When the system is filled with water, countless micro-battery systems will be formed in the device, forming an electric field in its action space. The new ecological [H], Fe produced during the process 2+ It can undergo oxidation-reduction reactions with many components in wastewater, such as chromophoric groups or auxochrom...
