Embodiment 1

[0031] Such as figure 1 shown, combined with figure 2 , the present invention provides a three-dimensional electrode reaction device, which includes a casing 1, a plurality of plate-type main electrodes 2, a plurality of particle electrodes 3, and a plurality of aeration tubes 4.

[0032] A partition plate 11 is arranged in the middle of the housing 1 and is divided into an upper reaction zone 12 and a lower water outlet chamber 13 by the partition plate 11. The housing 1 of the reaction zone 12 is provided with a water inlet 15 for sewage to flow in. Reaction zone 12. The water outlet chamber 13 is provided with a water outlet 17, and the treated purified water flows into the water outlet chamber 13 and is discharged through the outlet. Specifically, the water inlet 15 is connected to the external water inlet pipe 9, and the lower part of the water inlet pipe 9 is provided with evenly spaced small holes to ensure uniform water inlet. The water outlet 17 is externally conn...

Embodiment 2

[0041] The three-dimensional electrode reaction device of this embodiment is basically the same as that of Embodiment 1, the difference is: as Figure 4 As shown, the three-dimensional electrode reaction device is provided with two, respectively corresponding to a primary reactor a and a secondary reactor b, the water inlet pipe 9 of the primary reactor a communicates with the water outlet pipe 7 of the secondary reactor b, A cushion layer 19 is provided at the bottom of the secondary reactor b.

[0042] In the three-dimensional electrode reaction device of the present invention, the sewage flows along the pole plates in each compartment 14, avoiding short flow of sewage, making the sewage mix more uniform and shortening the residence time. The bottom of each compartment 14 is equipped with an aeration device 4, and the upper part is covered with an insulating frame 5 whose surface is a fine wire mesh. The insulating basket 5 protects the aeration tube from being pressed by th...

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...
