[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0033] Reference Figures 1 to 3 , which is a structural schematic diagram of the device for treating sulfur-containing organic wastewater in this embodiment. The device in this embodiment includes an outer cylinder 100 and a reaction tank 200 arranged inside the outer cylinder 100. In this embodiment, the outer cylinder 100 is a cylindrical structure with two ends open, and the reaction tank 200 is assembled in the outer cylinder 100 and the bottom of the reaction tank 200 extends out of the bottom of the outer cylinder 100. In this embodiment, the top of the reaction tank 200 is detachably connected with a cover body, and the sulfur-containing organic wastewater to be treated and an oxidant can be injected into the reaction tank 200 by disassembling the cover body. The oxidant in this embodiment is hydrogen peroxide and FeS n Powder as catalyst, that is, using Fenton-like catalytic system - FeS n / H2O2 is used to treat sulfur-containing organic wastewater.

[0034] In this embodiment, a Fenton-like catalytic system—FeS n / H2O2 is used to treat sulfur-containing organic wastewater, oxidizing the sulfur in the wastewater to form sulfate ions, and adding calcium ions to precipitate to achieve the purpose of desulfurization. In addition, hydrogen peroxide produces hydroxyl groups for the degradation of organic pollutants in the wastewater.

[0035] like Figures 4 to 6 As shown, it is a structural schematic diagram of the reaction tank 200 assembled in the outer cylinder 100. In this embodiment, a fixing frame 101 is fixedly connected to the top of the outer cylinder 100, and a stirring motor 102 is installed on the fixing frame 101. The power end of the stirring motor 102 is connected to a stirring shaft 104, and the stirring shaft 104 passes through the cover body on the top of the reaction tank 200 and extends into the reaction tank 200, and the end of the stirring shaft 104 located in the reaction tank 200 is connected to a stirring blade 104a; the stirring motor 102 can drive the stirring shaft 104 and the stirring blade 104a to rotate in the reaction tank 200, so that the sulfur-containing organic wastewater is stirred, so that the hydrogen peroxide and the catalyst in the wastewater oxidize and degrade the sulfur and organic matter in the wastewater, so as to achieve the purpose of wastewater treatment.

[0036] In this embodiment, in order to facilitate the pressure relief treatment of the reaction tank 200, this embodiment adopts mechanical pressure relief to intermittently exhaust the reaction tank 200. Specifically, in this embodiment, a rotating component 105 is also installed on the stirring shaft 104. Figure 7 As shown, the rotating assembly 105 includes a connecting rod 105a and a rotating ring 105b. One end of the connecting rod 105a is connected to the stirring shaft 104, and the other end of the connecting rod 105a is connected to the rotating ring 105b. The rotating ring 105b is located in the reaction tank 200 and fits against the side wall of the reaction tank 200. When the stirring shaft 104 rotates, the connecting rod 105a can drive the rotating ring 105b to rotate in the reaction tank 200. In this embodiment, a guide block 105c is fixedly connected to the surface of the rotating ring 105b. The guide block 105c is a peak-shaped structure, and the surface of the guide block 105c is a smooth guide surface, which is a peak top surface and a valley bottom surface respectively. In addition, in this embodiment, the connecting rod 105a can also stir the wastewater in the reaction tank 200 during the rotation process to achieve the purpose of uniform stirring. In addition, the surface of the reaction tank 200 in this embodiment is provided with an exhaust port 203, and as shown in FIG. Figure 6 as well as Figure 8As shown, the reaction tank 200 is also equipped with a pressure relief assembly 204, which includes a fixed rod 204a slidably assembled in the reaction tank 200, and the fixed rod 204a can only move up and down along the inner wall of the reaction tank 200 in the longitudinal direction. One end of the fixed rod 204a is connected to a sealing member 204b, and the sealing member 204b is sealingly slidably assembled on the exhaust port 203. When the fixed rod 204a moves upward, the sealing member 204b can be pushed to separate from the exhaust port 203 to achieve the purpose of exhaust pressure relief. When the fixed rod 204a moves downward, the sealing member 204b can be pulled into the exhaust port 203 to seal the exhaust port 203. In this embodiment, the other end of the fixed rod 204a abuts against the surface of the guide block 105c. When the guide block 105c rotates with the rotating ring 105b, the guide surface of the guide block 105c pushes the fixed rod 204a to move up and down, thereby achieving a pressure relief-sealing cyclic action effect to achieve intermittent pressure relief without manual monitoring.

[0037] In addition, in order to facilitate the up and down movement of the fixed rod 204a in the reaction tank 200, a ball joint is adopted at the end of the fixed rod 204a, and the ball joint abuts against the surface of the guide block 105c. When the guide block 105c rotates following the rotating ring 105b, it is convenient to drive the ball joint to drive the fixed rod 204a to move up and down in the reaction tank 200. In addition, in the present embodiment, a fixing ear is provided on the inner wall of the reaction tank 200, and the fixing rod 204a can move up and down in the reaction tank 200 by passing through the fixing ear. The setting of the fixing ear prevents the fixing rod 204a from swinging in the reaction tank 200, thereby promoting the effect of up and down movement. In addition, a spring 204c is also sleeved on the fixing rod 204a, one end of the spring 204c is connected to the end of the fixing rod 204a, and the other end is connected to the fixing ear. Therefore, when the guide block 105c rotates with the rotating ring 105b so that the peak surface abuts against the end of the fixing rod 204a, the fixing rod 204a is driven to move upward, and the spring 204c can be compressed so that the sealing member 204b is separated from the exhaust port 203 to realize pressure relief. When the end of the fixing rod 204a enters the valley bottom surface, the fixing rod 204a is reset, and the spring 204c drives the fixing rod 204a to move downward, thereby pulling the sealing member 204b into the exhaust port 203 to realize sealing. Therefore, in this embodiment, intermittent pressure relief is achieved by moving the fixing rod 204a up and down, thereby reducing the workload of operators.

[0038] In this embodiment, a guide block 105c is provided on the rotating ring 105b to form a peak top surface and a valley bottom surface to drive the pressure relief component 204 to move up and down. However, this embodiment includes but is not limited to the above-mentioned peak top surface and valley bottom surface structure. It is worth noting that as long as the surface of the rotating ring 105b is a wave surface structure that can drive the pressure relief component 204 to move up and down, the technical solution can be applied to this embodiment. Example

[0039] Reference Figures 1 to 3 , the difference between this embodiment and embodiment 1 is that the device for treating sulfur-containing organic wastewater in this embodiment is further provided with a supporting structure 300, the supporting structure 300 supports the device, and the device can swing when stirring the wastewater through the stirring shaft 104 and the stirring blade 104a. The specific supporting structure 300 includes a fixed base 301 and a lateral frame 302 symmetrically arranged on the surface of the fixed base 301, a driving shaft is connected between the lateral frame 302 and the outer cylinder 100, and a swing motor 304 is connected to the lateral frame 302, and the power end of the swing motor 304 is connected to the driving shaft through a reducer, so that the swing motor 304 can drive the driving shaft to rotate and then make the outer cylinder 100 and the reaction tank 200 inside it swing, so as to achieve the purpose of shaking the internal wastewater, ensure that the wastewater is mixed with the oxide and the catalyst more evenly, and achieve a better wastewater treatment effect.

[0040] In addition, in this embodiment, the reaction tank 200 is concentrically arranged in the outer cylinder 100, and the reaction tank 200 is rotatably connected to the outer cylinder 100. Figure 1 as well as Figure 2 As shown, an arc-shaped toothed plate 303 is fixedly connected to the surface of the fixed base 301, a connecting shaft 201 is mounted at the bottom of the reaction tank 200, and a gear 202 is mounted at the end of the connecting shaft 201, the gear 202 is meshed with the arc-shaped toothed plate 303, and when the swing motor 304 in this embodiment causes the outer cylinder 100 and the reaction tank 200 inside thereof to swing, the gear 202 at the bottom of the reaction tank 200 is meshed with the arc-shaped toothed plate 303, therefore, when the gear 202 moves along the surface of the arc-shaped toothed plate 303, the gear 202 rotates, and then the reaction tank 200 rotates inside the outer cylinder 100, thereby further achieving uniform mixing of the wastewater in the reaction tank 200 and improving the effect of wastewater treatment.

[0041] Working principle: In the utility model, sulfur-containing organic wastewater, oxides and catalysts can be injected into the reaction tank 200 by disassembling the cover body, and the stirring motor 102 drives the stirring shaft 104 and the stirring blade 104a to rotate to stir the wastewater, so that the wastewater, the oxides and the catalyst are fully mixed to achieve the purpose of wastewater treatment. In addition, the stirring shaft 104 rotates to drive the rotating ring 105b and the guide block 105c to rotate, and the guide block 105c drives the pressure relief component 204 in the reaction tank 200 to move up and down, specifically, the fixed rod 204a moves upward to seal the seal 2 04b is separated from the exhaust port 203 to achieve pressure relief, and when the fixing rod 204a is reset, the sealing member 204b can be pulled into the exhaust port 203 to achieve sealing. In addition, the swing motor 304 in this embodiment works to make the outer cylinder 100 and the reaction tank 200 swing, thereby enhancing the mixing effect. During the swinging process, the gear 202 at the bottom of the reaction tank 200 rotates due to the engagement with the arc-shaped tooth plate 303, thereby causing the reaction tank 200 to rotate itself in the outer cylinder 100, further enhancing the effect of mixing wastewater to improve the efficiency of wastewater treatment.

[0042] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
