Three-dimensional electrode reaction device

Abstract

The invention discloses a three dimension electrode reaction unit, which is characterized in that short flow of wastewater is avoided by arranging plate-type main electrodes placed in a parallel staggered manner, insulation baskets with holes and particle electrodes filled therein, aerator pipes, insulation frames of which the surfaces have fine wire screens, support pins and tees, so that the wastewater is more uniformly mixed and the retention time is simultaneously reduced; the aeration is more uniform, the degree of mixedness of the wastewater is deepened, and the mass transfer efficiency is greatly improved; the partitioning design of the particle electrodes can omit a discharge opening of a traditional device, so that loading and unloading of the particle electrodes are more convenient and cleaner, and the partitioning design of the particle electrodes also can block a short-circuit current difficult to overcome in a traditional three dimension electrode reaction unit, and economy, green and high efficiency are realized; a gas-liquid mixture can be removed while mixing and effluent discharging are performed; the occurrence of a siphon problem can be avoided; the height of the wastewater can be controlled through the length of a discharging tube, thus a basic parameter, namely the filling amount of the particle electrodes, is controlled, and a better treatment effect is further obtained.

Description

technical field [0001] The invention belongs to the field of three-dimensional electrode sewage treatment, and in particular relates to a three-dimensional electrode reaction device. Background technique [0002] Through literature review and relevant research, it is found that the electrocatalytic oxidation reactor in the existing research is difficult to get rid of the problems of electrode setup and reactor structure design simplification, and there are cases of breakthroughs in electrode setup, such as patent number 20151074092.6 Patent for invention: a method and device for treating phosphorus-containing wastewater using multi-plate baffle electrocoagulation technology. This invention has made a breakthrough in the setting of electrodes, but it is still a two-dimensional electrode, and the treatment process is only electrocoagulation, and the treatment object is only phosphorus-containing wastewater, and the scope involved is too narrow. At present, there are only a ha...
