[0002] Electrocatalytic oxidation technology is an oxidation reaction that uses electricity as a catalyst and hydrogen peroxide, oxygen, ozone, etc. as oxidants. The anode plate, cathode plate and wastewater are in contact with each other to oxidize the difficult-to-degrade organic matter in the wastewater, thereby achieving the effect of wastewater treatment. However, when wastewater is added to the fuselage, the wastewater contains more impurities, including those that cannot be treated by electrocatalytic oxidation and larger impurities, which results in the electrode plate and cathode plate being unable to oxidize all impurities during operation. At the same time, larger impurities will fill the gap between the cathode plate and the anode plate and block the water outlet. Utility Model Content

[0026] The utility model provides Figure 1-5 The electrocatalytic oxidation sewage treatment equipment shown comprises a body 1 and a water inlet 2 installed on the outer wall of the right end of the body 1;

[0027] A water outlet 6 is fixedly connected to the center of the left outer wall of the fuselage 1;

[0028] A plurality of anode plates 7 are fixedly connected to the inner wall of the lower end of the fuselage 1 at equal intervals from left to right;

[0029] A plurality of cathode plates 8 are fixedly connected to the inner wall of the lower end of the body 1 from left to right and located on the right side of the anode plate 7. The plurality of anode plates 7 and the cathode plates 8 are electrically connected to an external power source. First, wastewater to be treated is added to the body 1 through the water inlet 2. After the wastewater is added, the anode plates 7 and the cathode plates 8 are started, and appropriate oxidants such as hydrogen peroxide, oxygen and ozone are added. The current generated by the anode plates 7 and the cathode plates 8 and the oxidants added to the wastewater undergo an oxidation reaction, thereby decomposing impurities in the wastewater.

[0030] A storage frame 9 is provided at the lowermost side of the right end inner wall of the fuselage 1 to collect impurities in the wastewater poured in through the water inlet 2, and leakage holes 10 are provided inside the outer walls around the storage frame 9. A water inlet 11 that passes through the right end outer wall of the storage frame 9 near the upper side is provided inside. When wastewater is added to the water inlet 2, the wastewater will enter the interior of the storage frame 9 through the water inlet 11 for collection, and larger particles of impurities in the wastewater will be blocked, and the wastewater will leak out through the leakage holes 10 and continue to undergo oxidation decomposition reaction in the fuselage 1.

[0031] like Figure 3 and Figure 4 As shown, a handle 12 is fixedly connected to the center of the upper outer wall of the storage frame 9, and a baffle 13 is fixedly connected to the lowermost side of the left outer wall of the storage frame 9 and located on the lower inner wall of the fuselage 1 to limit the movement position of the storage frame 9. When the storage frame 9 is installed and used, the storage frame 9 can be moved by pulling the handle 12 outward, so as to clean the impurities collected in the storage frame 9. After the cleaning is completed, the storage frame 9 can be re-stuck in the position between the baffle 13 and the inner wall of the fuselage 1.

[0032] like Figure 2 As shown, the water inlet 11 is inclined, which can more accurately and comprehensively guide the wastewater transported by the water inlet 2 to the interior of the storage frame 9. The lower right corner of the storage frame 9 adopts an arc-shaped design to fit the inner wall of the fuselage 1, so that the storage frame 9 can be more tightly and stably fitted between the fuselage 1.

[0033] like Figure 5 As shown, a channel 5 is provided at the center of the upper outer wall of the fuselage 1, a filter 14 is fixedly connected to the lowermost side between the left and right inner walls of the channel 5, an adsorption bag a15 is provided on the upper outer wall of the filter 14 and between the left and right inner walls of the channel 5, an adsorption bag b16 is provided on the upper outer wall of the adsorption bag a15 and between the left and right inner walls of the channel 5, a plurality of upwardly opening jacks 19 are equidistantly provided inside the upper outer wall of the channel 5, and downwardly plugged fixing rods 18 are provided inside the plurality of jacks 19, and the gas generated during the oxidation reaction inside the fuselage 1 will move upward through the channel 5, and will pass through the adsorption bags a15 and b16 during the movement to adsorb the odor in the gas, thereby making the gas cleaner when discharged through the channel 5.

[0034] like Figure 5 As shown, a top cover 17 is fixedly connected between the upper outer walls of the plurality of fixing rods 18, which can prevent rainwater from entering the interior of the channel 5 on rainy days, causing the adsorption bag a15 and the adsorption bag b16 to become wet and unable to continue to be used. The adsorption bag a15 and the adsorption bag b16 are filled with activated carbon particles and bamboo charcoal particles respectively. The use of activated carbon particles and bamboo charcoal particles for filling can make the odor in the gas after the oxidation reaction be adsorbed more quickly and comprehensively, and the bamboo charcoal fragrance of the bamboo charcoal particles themselves can also cover the residual odor after treatment.

[0035] like Figure 1As shown, the upper outer wall of the fuselage 1 and the inner parts near the left and right sides are both transmission-connected with cover plates 4, and the upper outer walls of the two cover plates 4 are fixedly connected with handles 3 to control the opening and closing of the cover plates 4.
