Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection, and specifically relates to an electrocatalytic water treatment technology, in particular to a basket (frame) type three-dimensional electrode module filled with catalytic materials. Background Art

[0002] At present, in the field of water treatment technology, in addition to chemical dosing or ordinary electrochemical oxidation-reduction, coagulation and precipitation degradation, the most effective low-cost and high-degradation method for degrading toxic and harmful substances in water is based on the invention patent "ZL 2012 1 0398371.0", using basket (frame) type three-dimensional electrodes filled with high specific surface area activated carbon, activated carbon loaded with catalyst, biochar materials, and alloy catalytic materials. Under the action of catalysts, the above pollutants are degraded by low current density electrolysis; this technology can not only degrade COD and ammonia nitrogen, but also degrade heavy metals, phosphorus, arsenic and other toxic and harmful substances, and no chemical oxidants are needed. It has the advantages of easy operation, high degradation rate, low cost, no secondary ion pollution, and less solid waste. This is a brand-new technology with great application potential that may replace dosing technology and ordinary electrocatalytic technology in the future. However, in the actual production process, due to the use of basket (frame) type electrodes, the transportation, installation, operation and maintenance of its equipment are very cumbersome, which is not convenient for large-scale rapid promotion. Therefore, the utility model proposes a basket (frame) type three-dimensional electrode module filled with catalytic materials to solve the above problems in view of the equipment design of the above technology.

It is particularly noted that the shape of the utility model is by no means limited to a rectangular parallelepiped. Cylinders and other irregular bodies can also be made into the structure of the utility model. The utility model is implemented by the following technical solutions:
