A high-efficiency three-dimensional electrode reaction device for eliminating short-circuit current

Abstract

The invention relates to an efficient three-dimensional electrode reaction device capable of eliminating short-circuit current. The efficient three-dimensional electrode reaction device comprises an electrode reaction bed, a water outlet pipe and a water inlet pipe, wherein a water outlet and a water inlet of the electrode reaction bed are respectively communicated with the water outlet pipe and the water inlet pipe; the electrode reaction bed is also provided with two main electrodes and an insulating frame body arranged between the two main electrodes; through grooves are formed in the insulating frame body. The efficient three-dimensional electrode reaction device has the advantages that (1) the insulating frame body is filled with particle electrodes, so that the particle electrodes are prevented from being in direct contact with the main electrodes; therefore, the phenomenon of short-circuit current is avoided, the current efficiency and the bipolarity of the particle electrodes are improved, and the degradation efficiency of organic waste water is increased; (2) because of the design of the bottom raised part and the support part of an inner frame body at the upper part of the insulating frame body, a plurality of insulating frame bodies can be stacked, and the blocking of the particle electrodes is realized; (3) when being applied to a three-dimensional electrode electrocatalytic oxidation reaction bed, the efficient three-dimensional electrode reaction device is convenient to disassemble and easy to clean.

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an efficient three-dimensional electrode reaction device for eliminating short-circuit current. Background technique [0002] Using bipolar three-dimensional electrode electrocatalytic oxidation to treat refractory organic wastewater is an effective wastewater treatment technology. In the traditional three-dimensional electrode reaction bed, the particle electrodes are filled randomly. Although the mass transfer distance is shortened and the reaction area is increased, the particle electrodes are too densely packed, which is easy to generate short-circuit current and increase the energy consumption of the equipment; Insulating particles are used to avoid short-circuit current, because the particle electrodes will gradually separate from the insulating particles under the long-term erosion of water flow and air flow, so that the improvement effect cannot last; choosing se...
