[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 - 11 The present invention provides a technical solution: a new pollutant wastewater treatment device with reduced odor, comprising a treatment box 1, a degassing assembly 2 is installed on the top of the treatment box 1, a fixing frame 3 is connected to the bottom of the inner cavity of the treatment box 1, a flow disturbance mechanism 4 is installed inside the fixing frame 3, a plurality of packing cylinders 5 are installed in the flow disturbance mechanism 4, and the movement disturbance of the packing cylinders 5 is controlled by the flow disturbance mechanism 4, and a pretreatment mechanism 6 is installed on the front side of the treatment box 1, wherein the pretreatment mechanism 6 is connected to an external pumping device through a pipeline;

[0043] The flow disturbance mechanism 4 includes a plurality of support sleeves 406 sleeved on the outside of the packing tube 5. The front side of the support sleeve 406 is transmission-connected with a force block 403. The force block 403 contacts the water flow to disturb the movement of the support sleeve 406.

[0044] The spoiler mechanism 4 also includes a fixed plate 405 disposed between adjacent filling tubes 5, a connecting rod 407 is slidably connected to the top of the fixed plate 405, and the other end of the connecting rod 407 is connected to a corresponding position on one side of a supporting sleeve 406 at a corresponding position, and the shaking is absorbed by sliding the connecting rod 407 on the top of the fixed plate 405;

[0045] One side of the connecting rod 407 corresponding to the fixed plate 405 is connected with a connecting rod 408. The other end of the connecting rod 408 is rotatably connected with a control sleeve 411. One side of the control sleeve 411 is connected with a telescopic rod 409. The other end of the telescopic rod 409 is connected to the travel groove opened at the top of the fixed plate 405. A spring 410 is sleeved outside the telescopic rod 409. The two ends of the spring 410 are respectively connected to the corresponding positions on one side of the control sleeve 411 and the inner cavity of the travel groove.

[0046] The top of the support sleeve 406 is rotatably connected with a control rod 402. The other ends of a plurality of control rods 402 are rotatably connected with a row rod 401. The bottom of the row rod 401 is connected with a force-receiving block 403 through a connecting block 404. And the force-receiving block 403 is located on one side of the pretreatment mechanism 6. The water liquid discharged by the pretreatment mechanism 6 drives the force-receiving block 403 and the row rod 401 to move.

[0047] Specifically: through the designed flow disturbance mechanism 4, when the water liquid flowing out of the pretreatment mechanism 6 can contact the corresponding force-receiving block 403, the force-receiving block 403 can drive the row rod 401 to move through the connecting block 404 when being stressed. The movement of the row rod 401 can drive the top control rod 402 to pull the rear support sleeve 406. When the support sleeve 406 is pushed by the control rod 402, it can drive the inner packing cylinder 5 to slide in the travel groove. The sliding of the packing cylinder 5 can drive the inner packings to vibrate and rub against each other, and the accumulation of the biofilm can be reduced through the mutual vibration and friction between the packings, improving the biological treatment effect.

[0048] Furthermore, when the support sleeve 406 rotates, it can drive the adjacent connecting rod 407 to move. The movement of the connecting rod 407 can drive the connecting rod 408 and the control sleeve 411 to slide in the travel groove. The sliding of the control sleeve 411 can drive the telescopic rod 409 to compress and shorten. When the telescopic rod 409 is compressed, it can squeeze the external spring 410. The spring 410 can use its own elastic force to maintain the stability of the movement of the top connecting rod 407, avoiding the offset of the support sleeve 406 caused by the excessive movement of the connecting rod 407 and improving the shaking stability of the packing cylinder 5.

[0049] The bottom of the inner cavity of the fixed frame 3 is connected with a travel seat 8. The support sleeve 406 is slidably connected in the travel seat 8. The bottom of the inner cavity of the travel seat 8 is connected with a mounting plate 412. A plurality of limiting blocks 413 are connected to the top of the mounting plate 412 along the length direction. And the limiting blocks 413 are in contact with the bottom side of the packing cylinder 5.

[0050] Specifically: Through the designed fixing frame 3 and stroke seat 8, when the support sleeve 406 pulls the packing cylinder 5 to move, the packing cylinder 5 can contact the bottom side limit block 413 when moving. When the packing cylinder 5 contacts the protruding part of the limit block 413, it can move upward. And after the upward-moving packing cylinder 5 separates from the limit block 413, the packing cylinder 5 can reset by its own gravity, so that the reciprocating vibration force application of the packing cylinder 5 can be realized, which is beneficial to further improving the shaking treatment effect of the packing in the packing cylinder 5.

[0051] Please refer to Figure 8 and 9 , the pretreatment mechanism 6 includes a pretreatment seat 601, the pretreatment seat 601 is connected to the front side of the fixing frame 3, a mounting plate 412 is installed on the top of the pretreatment seat 601, and a plurality of communication grooves 602 are arranged in an array on the opposite sides of the fixing frame 3 and the pretreatment seat 601, and the adjacent communication grooves 602 are penetrated. An installation frame 603 is connected between the adjacent communication grooves 602 in the inner cavity of the pretreatment seat 601. The cross-sectional shape of the installation frame 603 is U-shaped, and an electrode plate 604 is connected to the inner side of the installation frame 603;

[0052] The cross-sectional shape of the electrode plate 604 is V-shaped, and the V-shaped tip of the electrode plate 604 faces the water inlet side of the pretreatment seat 601. A spoiler rod 605 is connected between the adjacent electrode plates 604 in the inner cavity of the pretreatment seat 601, and a drainage plate 606 is connected to the outer peripheral side of the spoiler rod 605 far from the outer peripheral side of the electrode plate 604.

[0053] Specifically: Through the designed pretreatment mechanism 6, when the new pollutant wastewater to be treated is pumped into the treatment tank 1 from an external pumping device, the wastewater can enter the pretreatment seat 601. At this time, the spoiler rod 605 and the drainage plate 606 can make the wastewater generate a vortex in the pretreatment seat 601, and the vortex can be guided by the V-shaped electrode plate 604 and then pass through the communication groove 602 into the treatment tank 1 at one time. The electrode plate 604 can decompose volatile precursor substances through a microcurrent to inhibit the generation of odors and improve the pretreatment deodorization effect.

[0054] The degassing assembly 2 includes a fixing ring 201, and a plurality of aeration pipes 202 are connected around the bottom of the fixing ring 201 along the axis. A plurality of aeration nozzles 203 are connected equidistantly along the axis inside the aeration pipes 202, and the fixing ring 201 is connected to an external purge air pump through a pipeline;

[0055] There is an empty slot in the treatment tank 1, and a plurality of reaction fillers 204 are connected around the inner cavity of the empty slot. A plurality of filling holes 205 are opened on one side of the reaction filler 204, and photocatalysts are filled in the filling holes 205. A ventilation part 7 is connected to the top of the treatment tank 1, and the air outlet of the ventilation part 7 is connected to an air outlet ring through a pipeline, and the air outlet ring is connected to the top of the empty slot. A light irradiator is connected to the bottom side of the air outlet ring corresponding to the empty slot.

[0056] Specifically, after the sewage enters the treatment tank 1 through pretreatment electrolysis and reacts, the gas generated by the reaction can be pumped by the exhaust part 7 when rising and then sent into the empty tank of the treatment tank 1. The air entering the empty tank of the treatment tank 1 can carry out photocatalyst purification and deodorization with the reaction filler 204. The air after purification and deodorization can be discharged through the pipeline connected to the outside of the treatment tank 1. By introducing the escaped waste gas into the photocatalytic decomposition channel in the empty tank, it is beneficial to reduce the odor generated in the treatment of new pollutant wastewater. And through the designed aeration pipe 202 and aeration nozzle 203, external aeration pumps can be used to aerate the aeration pipe 202 and the aeration nozzle 203, improving the purification effect of the biological filler and being conducive to further reducing the accumulation of odor through aeration. Compared with the traditional open tank body, it reduces the escape of odor and improves the comfort level.

[0057] Working principle: When in use, when the liquid flowing out of the pretreatment mechanism 6 contacts the corresponding force-receiving block 403, the force-receiving block 403 is stressed and drives the discharge rod 401 to move through the connecting block 404. The movement of the discharge rod 401 drives the top control rod 402 to pull the rear support sleeve 406. When the support sleeve 406 is pushed by the control rod 402, it drives the inner packing cylinder 5 to slide in the stroke groove. The sliding of the packing cylinder 5 drives the inner packings to vibrate and rub against each other. When the support sleeve 406 rotates, it drives the adjacent connecting rod 407 to move. The movement of the connecting rod 407 drives the connecting rod 408 and the control sleeve 411 to slide in the stroke groove. The sliding of the control sleeve 411 drives the telescopic rod 409 to compress and shorten. When the telescopic rod 409 is compressed, it squeezes the external spring 410;

[0058] When the support sleeve 406 pulls the packing cylinder 5 to move, the packing cylinder 5 contacts the bottom side limit block 413 when moving. The packing cylinder 5 contacts the protruding part of the limit block 413 and moves upward. After the upward-moving packing cylinder 5 separates from the limit block 413, the packing cylinder 5 uses its own gravity to reset, realizing the reciprocating vibration force application of the packing cylinder 5;

[0059] The wastewater enters the pretreatment seat 601. At this time, the turbulence rod 605 and the diversion plate 606 cause the wastewater to generate eddies in the pretreatment seat 601. The eddies are guided by the V-shaped electrode plate 604 and then pass through the communication groove 602 once and enter the treatment tank 1. The electrode plate 604 decomposes volatile precursor substances through microcurrent;

[0060] After the sewage enters the treatment tank 1 through pretreatment electrolysis and reacts, the gas generated by the reaction is pumped by the exhaust part 7 when rising and then sent into the empty tank of the treatment tank 1. The air entering the empty tank of the treatment tank 1 carries out photocatalyst purification and deodorization with the reaction filler 204. The air after purification and deodorization is discharged through the pipeline connected to the outside of the treatment tank 1. By introducing the escaped waste gas into the photocatalytic decomposition channel in the empty tank, the odor is reduced.
