[0028] See also Figure 1-5 , an embodiment provided by the utility model:
[0029] An activated coke biofilm adsorption reactor comprises a plurality of reaction tanks 1, wherein the plurality of reaction tanks 1 are operated in parallel and can be operated independently, wherein the inner walls of the plurality of reaction tanks 1 are all provided with a water inlet pipe 6, and one end of the water inlet pipe 6 is connected to a first flow guide pipe 7, both ends of the first flow guide pipe 7 are both connected to a second flow guide pipe 8, and both ends of the second flow guide pipe 8 are both connected to an octopus water distributor 9, one side of the octopus water distributor 9 is connected to a water absorption hood 513, and the bottom end of the water absorption hood 513 is connected to a support frame 514, the support frame 514 is fixedly connected to the inner wall of the bottom end of the reaction tank 1, and a filter bed 211 is arranged inside the reaction tank 1, a fixing seat 2 is fixedly installed on the top of the reaction tank 1, and a feeding pipe 3 is arranged on the outer surface of the fixing seat 2.
[0030] Furthermore, a flange 311 is installed at one end of the feeding pipe 3, and a plurality of distribution pipes 312 are connected to the bottom end of the feeding pipe 3. The flange 311 is connected to the feeding tank through a pipeline. By installing the flange 311 at one end of the feeding pipe 3, it is ensured that the connection between the feeding pipe 3 and the feeding tank is stable and not easy to loosen. At the same time, the design of the flange 311 also provides good sealing, prevents leakage of materials during transportation, and ensures the safe operation of the reactor. The design of the plurality of distribution pipes 312 also makes the distribution of materials inside the reactor more controllable, which is convenient for operators to adjust and optimize.
[0031] Furthermore, a fixing frame 4 is fixedly installed on the inner wall of the top of each of the multiple reaction pools 1, and a plurality of lifters 5 are installed on the outer surface of the fixing frame 4, one end of the plurality of lifters 5 is connected to a stripping tube 511, and one end of the stripping tube 511 is connected to a connecting suction cup 512, and one end of the connecting suction cup 512 is connected to an octopus water distributor 9, and the octopus water distributor 9 is interconnected with the inner wall of the stripping tube 511 and the water absorption hood 513. This design enables saturated adsorption media such as activated coke to be easily lifted and cleaned online through the stripping tube, which greatly simplifies the operation process.
[0032] Furthermore, a plurality of aeration tubes 111 are provided at the bottom end of the water absorbing hood 513, and the plurality of aeration tubes 111 effectively prevent the filter material from being compacted and maintain good filtering performance of the filter material.
[0033] Furthermore, a reinforcement frame 711 is fixedly installed on the outer surface of the first flow guide pipe 7, which enhances its structural stability and prevents the pipe from being deformed or damaged due to water flow impact or other external forces.
[0034] Furthermore, the bottom ends of the multiple groups of elevators 5 are all connected to a conveying pipe 212, and the conveying pipe 212 discharges the material to a vibrating screen, and after being vibrated and dehydrated by the vibrating screen, it is loaded into a ton bag. Through effective dehydration treatment and storage methods, the impact of the adsorption medium on the environment during transportation and storage can be reduced, and energy consumption and costs are also reduced.
[0035] Furthermore, the filter bed 211 is composed of porous carbonaceous filter material, which has extremely high specific surface area and porosity, and can provide a large number of adsorption sites, thereby effectively adsorbing pollutants such as organic matter and heavy metal ions in water. This makes the filter bed 211 perform well in treating sewage and can achieve a high removal rate and purification effect.
[0036] Working principle: First, in the reaction tank 1, the sewage first enters through the water inlet pipe 6, and then is guided by the first guide pipe 7 and the second guide pipe 8, and finally evenly distributed to the eight-claw water distributor 9. The design of the eight-claw water distributor 9 ensures the uniform distribution of water flow in the reaction tank, so that the sewage can fully contact with the adsorption medium such as activated coke in the reaction tank. The water flows from bottom to top through the filter bed 211. During this process, pollutants such as COD that are difficult to biodegrade are adsorbed and removed by the activated coke, thereby achieving purification. The filtered clean water gathers at the top of the reaction tank and overflows through the overflow port to complete the treatment process. As the filtration process proceeds, the adsorption medium such as activated coke at the bottom of the reaction tank will gradually become saturated. In order to maintain the continuous and efficient operation of the reactor, these saturated adsorption media need to be cleaned and regenerated regularly. At this time, by starting the lifter 5 on the fixed frame 4, the adsorption medium is lifted to the stripping pipe 511 and connected to the eight-claw water distributor 9 through the connecting suction cup 512. The design of the stripping pipe 511 allows the adsorption medium to be cleaned online by introducing a medium such as air or steam to remove pollutants attached thereto. The cleaned sewage is collected by the water absorbing hood 513 and discharged through the conveying pipe 212. The cleaned adsorption medium is then transported to the vibrating screen through the conveying pipe 212 for further dehydration. The vibrating screen removes excess water from the surface of the adsorption medium through vibration and packs it into a ton bag for subsequent use or disposal.
