[0016] Compared with the prior art, the technical scheme of the present application has the following advantages:

[0017] (1) The pool body is provided with a circulating water pump, a water pipe assembly, a water suction pipe, a water discharge pipe and a nozzle assembly. The device improves the mixing efficiency and diffusion uniformity of ozone and sewage through the design of the circulating mechanism and the nozzle assembly. The circulating water pump cooperates with the negative pressure dissolver. When the water flows through the negative pressure dissolver, negative pressure is generated, and ozone in the ozone pipeline is automatically sucked, so that gas-liquid mixing is efficient. This design avoids the problems of high energy consumption and uneven mixing of the traditional aeration method, improves the utilization rate of ozone, and the agitation function of the dynamic rotating nozzle. When the ozone mixed water is sprayed through the horizontal nozzle and the vertical nozzle, the reaction force drives the rotating horizontal pipe to rotate, so that the water flow is in a three-dimensional diffusion state, which not only expands the ozone contact area, but also accelerates the decomposition of pollutants through hydraulic shear force. This design shortens the reaction time and realizes the gradient treatment of sewage through the combination of the multi-stage reaction zone formed by the water barrier and the water guide wall and the directional injection of the nozzle. The short flow phenomenon is avoided, and the ozone and pollutants are fully reacted. In summary, this technology converts the mass transfer bottleneck of traditional ozone oxidation into an advantage, and is especially suitable for the treatment of refractory organic wastewater;

[0018] (2) The design of the floating mechanism has the functions of sludge interception and operation convenience, solves the pain point of frequent maintenance of traditional ozone catalytic equipment, and has the functions of intercepting water level changes. The floating shell and the water leakage hole structure can buffer the water flow impact during the water level rising process, avoid the bottom sludge from surging, intercept floating objects and suspended sludge on the water surface, significantly reduce the risk of subsequent filter plate blockage, and realize the intelligentization of the spring locking mechanism. When the water level reaches the preset height, the sliding rod is automatically clamped into the lock groove through the spring elastic force, and the position of the floating shell is fixed. This mechanical triggering does not require external energy and has high reliability. The floating shell is designed to be clean. After drainage, maintenance personnel only need to pull the vertical rod to unlock the floating shell, quickly take it out for cleaning, and the hollow structure of the floating shell reduces the manual carrying strength. In addition, the mechanism can be reused, has a long service life, and reduces the replacement cost. This design is especially suitable for high-suspended solid wastewater scenes, such as printing and dyeing and papermaking industries. BRIEF DESCRIPTION OF DRAWINGS

[0037] The nozzle assembly 25 comprises a connecting elbow pipe 251 fixedly connected below the water discharge pipe 24, a connecting horizontal pipe 252 fixedly arranged at one end of the connecting elbow pipe 251, two elbow pipes 253 fixedly connected at two ends of the connecting horizontal pipe 252 respectively, a rotating horizontal pipe 254 rotatably connected at one end of the elbow pipe 253, a plurality of vertical nozzles 255 fixedly arranged on the rotating horizontal pipe 254, a horizontal nozzle 256 fixedly arranged on each side of the rotating horizontal pipe 254 respectively, and two horizontal nozzles 256 fixedly arranged at two ends of the rotating horizontal pipe 254 respectively.

[0038] A plurality of support walls 11 are fixedly connected inside and below the pool body 1, the support walls 11 being provided with through cavities corresponding to the nozzle assemblies 25, a filter plate 12 being fixedly connected at the upper end of the support wall 11, an ozone catalyst being placed on the filter plate 12, the ozone catalyst being placed at a height of 400-600 mm, so that the design and use amount of the catalyst is reduced, the investment cost is directly reduced, and the process technology does not need to be backwashed, is simple to operate, and has a long service life, a plurality of filter head handles 13 being fixedly arranged on the filter plate 12, and a pipe mechanism 3 comprising a water inlet pipe 31 fixedly arranged on one side of the support wall 11 and a water outlet pipe 32 fixedly arranged on the other side of the support wall 11.

[0039] Four water isolation walls 14 are fixedly connected in the pool body 1, the water isolation walls 14 dividing the pool body 1 into a plurality of reaction areas, a lower water through hole 16 being arranged below three water isolation walls 14 close to the water inlet pipe 31, and an upper water through hole 15 being arranged above one of the water isolation walls 14 close to the water outlet pipe 32.

[0040] Three water guide walls 17 are fixedly arranged inside the pool body 1, and the three water guide walls 17 are arranged on the side of the water stop wall 14 close to the water inlet pipe 31, a plurality of water suction pipes 23 and water discharge pipes 24 are arranged between the water guide wall 17 and the water stop wall 14, the lower water hole 16 corresponds to the nozzle assembly 25, and the rotating horizontal pipe 254 is located below the filter plate 12.

[0041] The floating mechanism 4 further comprises a lock groove 45 arranged above the water stop wall 14 and the water guide wall 17 close to the water inlet pipe 31, and the lock groove 45 corresponds to the sliding rod 444; when the floating shell 41 rises, the rotating ball 446 is in a rotating state when it contacts the water stop wall 14 and the water guide wall 17, thereby reducing the friction between the sliding rod 444 and the water stop wall 14 and the water guide wall 17.

[0042] The working principle of the present application is as follows: in use, water is injected into the pool body 1 through the water inlet pipe 31; as the water is injected, the water overflows the first water guide wall 17 close to the water inlet pipe 31, enters between the water guide wall 17 and the water stop wall 14, and then enters the other side of the water stop wall 14 from the lower water hole 16 below the water stop wall 14, and then overflows the second water guide wall 17, enters the other side of the second water stop wall 14 from the lower water hole 16 below the second water stop wall 14, and then enters the other side of the third water stop wall 14, and then overflows the upper water hole 15 on the fourth water stop wall 14, and then is discharged from the water outlet pipe 32; when the water enters the side of the three water stop walls 14 close to the water inlet pipe 31, it is blocked by the filter plate 12, and then enters the space above the filter plate 12 through the filter head handle 13.

[0043] The circulating water pump 21 draws water in the pool body 1 through the water inlet pipe 221 and the water suction pipe 23, and then discharges the water into the first water outlet pipe 222; the water flow passes through the negative pressure dissolver 223 to suck the ozone in the ozone pipe 225 into the negative pressure dissolver 223 and mix with the water; another circulating water pump 21 draws the water mixed with ozone and then discharges the water from the second water outlet pipe 226 and the water discharge pipe 24; the water mixed with ozone is discharged from the water discharge pipe 24 into the connecting elbow pipe 251, enters the connecting horizontal pipe 252 through the connecting elbow pipe 251, and then enters the elbow pipe 253 and the rotating horizontal pipe 254; part of the water mixed with ozone is sprayed from the vertical nozzle 255, and part of the water mixed with ozone is sprayed from the horizontal nozzle 256; because the horizontal nozzle 256 is arranged, the water mixed with ozone is sprayed in two different directions, so that the rotating horizontal pipe 254 rotates around the elbow pipe 253, the spraying area of the water mixed with ozone is increased, and the water is stirred to increase the mixing speed of other water and ozone.

[0044] When the water overflows the first water guide wall 17, the floating shell 41 is gradually lifted. When the water level rises, the water overflowing the water guide wall 17 directly hits the floating shell 41 and does not directly contact the water below the floating shell 41, preventing the impact of the water from making the water below more turbid. The water hitting the floating shell 41 flows into the space below the floating shell 41 through the water leakage hole 43. As the floating shell 41 rises, a small amount of sludge is intercepted. When the floating shell 41 rises to the highest position, the sliding rod 444 is at the same height as the lock slot 45. The sliding rod 444 no longer contacts the water barrier 14 and the water guide wall 17 through the rotating ball 446. The spring 445 pushes the sliding rod 444 out of the sliding slot 442. The sliding rod 444 is inserted into the lock slot 45, fixing the floating shell 41 between the water barrier 14 and the water guide wall 17. When it is necessary to clean the sludge in the pool body 1, the water in the pool body 1 is drained, and all measures are prepared. After entering the pool body 1, the sliding rod 444 is moved into the sliding slot 442 by pinching the vertical rod 447. Then, the floating shell 41 is taken out from between the water barrier 14 and the water guide wall 17. The sludge on the floating shell 41 is cleaned. Then, the floating shell 41 is placed back between the water barrier 14 and the water guide wall 17, so that the floating shell 41 is located near the bottom between the water barrier 14 and the water guide wall 17.

[0045] The above examples are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims.
