[0002] In the production process of flame retardants, high-concentration wastewater with complex components and a large amount of refractory organic pollutants is generated. The traditional wastewater treatment method often adopts multiple sets of devices in series, and sequentially carries out flocculation precipitation, chemical oxidation and deep filtration. This segmented treatment method has problems such as large equipment area, long process flow, high energy consumption, and secondary pollution caused by material transfer between different processes.

[0040] Embodiment: as Figure 1 and Figure 2The application discloses an environment-friendly wastewater treatment device for flame retardant production, which comprises a treatment barrel 1, wherein the treatment barrel 1 is a cylindrical barrel with two cavities in the inside, a driving assembly 2 is arranged through the center of the treatment barrel 1, a discharging assembly 3 is arranged at the inside center of the treatment barrel 1, a stirring assembly 4 is arranged at the periphery of the driving assembly 2 in the inside of the treatment barrel 1, and a purifying assembly 5 is arranged at the lower side of the driving assembly 2 in the inside of the treatment barrel 1.

[0042] As Figures 2 to 7As shown, the drive assembly 2 comprises a first mounting frame 21 arranged at the upper side of the processing barrel 1 and a drive module 211 fixedly arranged at both sides of the first mounting frame 21. The drive module 211 is composed of a motor and a roller, and has a constraint roller arranged at the side surface thereof. The drive module 211 is constrained to rotate at the upper side of the processing barrel 1, so as to drive the first mounting frame 21 to stably rotate concentrically at the upper side of the processing barrel 1. A fixed rod 22, a first movable cylinder 23 and a movable rod 24 are arranged at the lower side of the first mounting frame 21 and penetrate the processing barrel 1. The fixed rod 22 is arranged at the upper inside of the processing barrel 1 and fixedly installed at the central position of the lower side of the first mounting frame 21. The movable rod 24 is arranged at the lower inside of the processing barrel 1. The first movable cylinder 23 is movably sleeved at the side of the movable rod 24. The first movable cylinder 23 and the movable rod 24 are arranged at the lower side of the fixed rod 22. The fixed rod 22 is a cylindrical rod. The movable rod 24 is a "T"-shaped cylindrical rod. The first movable cylinder 23 is a hollow cylindrical cylinder. A first battery module 221 is fixedly arranged in the fixed rod 22 and extends out of the first mounting frame 21 at the upper end thereof. A second battery module 241 is fixedly arranged in the movable rod 24. A first gear 222 is arranged at the central position of the lower side of the fixed rod 22 and at the upper side of the movable rod 24. A gear ring 231 is fixedly installed at the inner side of the first movable cylinder 23 and corresponds to the position of the first gear 222. A second gear 242 is arranged between the first gear 222 and the gear ring 231 in a circumferential array and at equal intervals. A constraint rod 243 is rotatably arranged at the central position of the second gear 242 and fixedly installed at the upper side of the movable rod 24. The first gear 222, the gear ring 231 and the second gear 242 form a planetary gear assembly. A first connecting rod 223 is fixedly installed at the lower side of the fixed rod 22 and has a spline sleeve arranged at the side surface thereof. The first gear 222 is electrically connected to the first battery module 221 at the upper end of the first connecting rod 223 penetrating the fixed rod 22. A second connecting rod 244 is fixedly installed at the upper side of the second battery module 241 and electrically connected to the first connecting rod 223 at the rotating contact point penetrating the movable rod 24. A first electric push rod 25 is arranged at the side of the first movable cylinder 23 and fixedly arranged at the central position inside the processing barrel 1. The first electric push rod 25 is externally connected to a power supply through an electric wire. A damping block 251 is fixedly installed at the output end of the first electric push rod 25 and elastically attached to the side of the first movable cylinder 23. The damping block 251 is a circular block made of elastic and wear-resistant material.Specifically, by default, the first electric push rod 25 pushes the damping block 251 to adhere to the side of the first movable cylinder 23, thereby damping and fixing the first movable cylinder 23. At this time, the first mounting frame 21 is driven to rotate by the driving module 211, and the fixed rod 22 is synchronously driven to rotate by the first mounting frame 21, so that the first connecting rod 223 rotates with the fixed rod 22, and the first gear 222 is constrained to rotate by the first connecting rod 223. At this time, the first movable cylinder 23 is constrained to keep the gear ring 231 stationary, the second gear 242 is engaged with the first gear 222 and the gear ring 231, and the second gear 242 can revolve integrally inside the gear ring 231. The second gear 242 can drive the movable rod 24 to rotate through the constraint rod 243. At this time, the speed can be increased to speed up the stirring. In addition, when the first electric push rod 25 pulls the damping block 251 away from the side of the first movable cylinder 23, the movable rod 24 and the components connected thereto have a running damping, and the speed is relatively low. At this time, the rotation of the first gear 222 will drive the second gear 242 to mainly rotate on the constraint rod 243, and the rotation of the second gear 242 will drive the gear ring 231 engaged therewith to rotate, thereby driving the first movable cylinder 23 to revolve. At this time, the speed can be reduced to slow down the stirring. The first connecting rod 223 and the second connecting rod 244 are connected and matched, so that the first battery module 221 and the second battery module 241 form an integral power supply combination to directly supply power to the subsequent components, thereby reducing the connection line arrangement between electronic components.

[0043] The arranged discharging assembly 3 can realize the partition processing in the processing barrel 1, the material flow between the regions, and the centralized discharge of the sediment, and the like.

[0044] As Figure 2 , Figure 3 and Figures 7 to 10As shown, the discharge assembly 3 comprises a discharge pipe 31 which is arranged in a circumferential array at the center of the side of the treatment barrel 1 and penetrates the treatment barrel 1 at two positions of the upper and lower cavities, the discharge pipe 31 is a "C" shaped circular pipe, a connecting pipe 311 is fixedly arranged at the side of the discharge pipe 31 and is connected to a liquid supply to supply Fenton oxidation solution (hydroxyl radicals with super strong oxidizing property generated by the reaction of ferrous ions and hydrogen peroxide), a second mounting bracket 32 is fixedly installed at the upper inner side of the discharge pipe 31, the second mounting bracket 32 is a circular ring bracket with a fan-shaped slot opened at the side, a block 321 is arranged in close contact with the side of the second mounting bracket 32, the block 321 is a circular block with a hollow side, the block 321 can block the fan-shaped slot of the side of the second mounting bracket 32, a mounting rod 322 is fixedly installed at the inner side of the block 321 and extends out through the center position of the second mounting bracket 32, the mounting rod 322 is a cylindrical rod with a tapered side, a first support cylinder 323 is fixedly connected between the side of the second mounting bracket 32 and the inner side of the block 321 and movably sleeved at the side of the mounting rod 322, the first support cylinder 323 is a corrugated cylinder made of elastic material; Specifically, the subsequent components can trigger the extrusion of the mounting rod 322, so that the mounting rod 322 pulls the first support cylinder 323 to deform away from the side of the second mounting bracket 32, the internal wastewater can flow from the second mounting bracket 32 into the discharge pipe 31, and then flow to the lower cavity of the treatment barrel 1 through the discharge pipe 31, and the connecting pipe 311 can supply Fenton oxidation solution to oxidize and degrade the pollutants in the wastewater at the same time;

[0045] The side circumferential array of the processing barrel 1 is equidistantly provided with a discharge groove 33, and the discharge groove 33 is arranged at the staggered position of the discharge pipe 31. The discharge groove 33 is a trapezoidal groove, and the discharge groove 33 is located between the two cavities of the processing barrel 1. The bottom wall of the discharge groove 33 is equidistantly provided with a filter hole 331 penetrating through the processing barrel 1. The top wall of the discharge groove 33 is symmetrically provided with a slot 34 penetrating through the processing barrel 1. The inside of the slot 34 is clamped and installed with a baffle plate 341. The baffle plate 341 is a double-convex rectangular plate. The top wall of the discharge groove 33 is provided with an active cavity 35 penetrating through the processing barrel 1 at the position between the slots 34. The active cavity 35 is a cylindrical cavity with a cross-section in the shape of a cross. The inside of the active cavity 35 is movably installed with a trigger rod 351, and the lower side of the trigger rod 351 is fixedly installed on the side of the baffle plate 341.

The flocculated material can be discharged from the discharge groove 33 for centralized collection.

[0046] The stirring assembly 4 can be used to adjust the stirring centrifugal force in different areas inside the processing barrel 1, and can be used in cooperation with the remaining components.

A trigger block 43 is fixedly installed at the output end of the second electric push rod 42. The trigger block 43 is an arc-shaped block. Specifically, the second electric push rod 42 can push and pull the trigger block 43 to adjust the position inside the processing barrel 1. When the fixed frame 41 rotates with the fixed rod 22 and the movable rod 24, the trigger block 43 can be used to stir the material in the processing barrel 1 with different stirring centrifugal forces. The second electric push rod 42 on the side surface of the fixed rod 22 pushes the trigger block 43 to the position of the trigger rod 351 or the mounting rod 322.

The second movable cylinder 55 is a circular ring cylinder with an “L”-shaped cross section. An array of cleaning plates 56 is fixedly installed on the inner side of the second movable cylinder 55 and is arranged in an interleaved manner with the flow guide grooves 52 on the side of the purification frame 51. A matching groove 57 is formed through the side of the second movable cylinder 55 corresponding to the position of the discharge pipe 31. Specifically, when the second electric push rod 42 on the side of the movable rod 24 pushes the trigger block 43 to be attached to the inner side of the second movable cylinder 55 during partitioned treatment, the rotation of the movable rod 24 can drive the second movable cylinder 55 to rotate synchronously, so that the cleaning plates 56 block the flow guide grooves 52, and the second movable cylinder 55 blocks the lower side of the discharge pipe 31. At this time, the lower cavity inside the treatment barrel 1 can be used for separate oxidation degradation operation. After oxidation degradation is completed, the second movable cylinder 55 is driven to rotate so that the matching groove 57 corresponds to the discharge pipe 31, and the cleaning plates 56 are arranged in an interleaved manner with the flow guide grooves 52. At this time, the wastewater flows into the inner side of the purification frame 51 from the flow guide grooves 52, and the permeable membrane filter core 53 and the activated carbon filter core 54 are used for biological membrane filtration to completely oxidize and decompose small-molecule organic matter and remove trace amounts of refractory COD and color remaining after biochemical treatment.
