Problems solved by technology

However, the existing iron-carbon micro-electrolysis process has exposed the following problems during operation: iron filings packing compaction and packing bed channeling. After the iron-carbon micro-electrolysis method has been in operation for a period of time, sewage will be generated in the packing after the iron filings packing is agglomerated. Ditching, making the effluent water quality worse
And the iron-carbon micro-electrolysis reaction is generally carried out under acidic conditions, which limits its scope of application to a certain extent.

Abstract

The invention relates to an iron-copper microelectrolysis reaction tank and a preparation method for a copperized iron wire net plate. Both ends of a tank body of the iron-copper microelectrolysis reaction tank are provided with a water inlet chamber and a water outlet chamber, a microelectrolysis reactor is arranged between the water inlet chamber and the water outlet chamber, sewage enters a water distribution area from the water inlet chamber via a water inlet and then the microelectrolysis reactor via a water distribution buffer plate, and is electrolyzed, the microelectrolysis reactor comprises a plurality of parallel copperized iron wire net plates, and both opposite edges of each copperized iron wire net plate are respectively arranged on both opposite sidewalls of the tank body. The electrolyzed sewage overflows a water outlet weir of the water outlet chamber. The structure of the iron-copper microelectrolysis reaction tank is simple, the applicable water quality range is wide, the cost is low, the service life is long, the chroma, toxicity and CODCr of organic waterwater can be effectively decreased, and the biodegradability of sewage can be enhanced. Copper can be firmly attached on the surfaces of the iron wire nets, and cannot easily come off, and low cost and low energy consumption are truly realized in the process of sewage treatment.

Description

technical field [0001] The invention relates to a preparation method of an iron-copper micro-electrolysis reaction tank and a copper-plated wire mesh board, belonging to the field of sewage treatment. Background technique [0002] 2 After the 1950s, due to the development of the modern chemical industry, a large number of artificially synthesized organic compounds, such as synthetic plastics, synthetic fibers, organic pesticides, synthetic rubber, surfactants, etc., will be produced in large quantities during the production and use of these organic compounds According to the "National Environmental Statistical Bulletin", by the end of 2008, among the total wastewater discharge in China, the industrial organic wastewater accounted for 44.3%. The pollutants in the wastewater are complex and contain a variety of toxic substances. , the concentration is high, and it often contains many refractory organic substances, such as nitroaromatic compounds, polycyclic aromatic hydrocarbo...
