Micro-electrolytic reactor

Abstract

The invention relates to a micro-electrolytic reactor comprising a waste water reservoir with a water inlet and a water outlet, wherein an acid and corrosion resistant coating layer is coated on the inner wall of the reservoir; a grille is arranged at the lower part of the reservoir and used for supporting a microelectrode; an aeration pipe network is arranged at the bottom of the reservoir; the microelectrode is contained in a corrosion resistant mesh bag which is made of filter cloth; 50-200 meshes of holes are uniformly distributed on the corrosion resistant mesh bag to guarantee air and water permeability; and the microelectrode is composed of haydite, silica, titanium dioxide, carbon powder and iron powder and has the total specific gravity of about 1. In the micro-electrolytic reactor, the structure of a conventional waste water reservoir is adopted for solving a microelectrode deposition problem which troubles the waste water treatment industry for a long time, greatly enhancing the efficiency of a micro-electrolytic reaction and prolonging the service life of a microelectrode material in the waste water treatment, and benefiting the replacement of the microelectrode material; in the mean time, the reforming of a traditional waste water reservoir is easy with little input and quick response; and moreover, the stirring intensity during the treatment process can be greatly reduced, and the operation and maintenance costs of equipment are reduced.

Description

technical field [0001] The invention relates to a microelectrolysis reaction device for wastewater treatment, in particular to a microelectrolysis reactor comprising a microelectrode package and a reaction pool containing the microelectrode package. Background technique [0002] Since the micro-electrolysis technology was invented by former Soviet scientists in the 1970s, theoretical research has become increasingly mature. However, because the micro-electrode materials used are iron and carbon powders, which are easily deposited and cause short circuits in micro-batteries, it has not been realized for a long time. Industrial application . The novel microelectrode material (CN200910038783.1) design scheme proposed by the present inventor adds air-permeable and lightweight ceramsite in the composition of the microelectrode material, which can overcome the disadvantages of easy deposition of the microelectrode, and make the industrial application of the microelectrode technolo...
