Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an intelligent treatment system for wastewater from the production of prepared dishes. Background Art

[0002] The production of pre-prepared meals generates large amounts of wastewater containing pollutants such as organic matter, grease, suspended solids, and salt. If discharged without effective treatment, this wastewater can cause serious environmental pollution, such as eutrophication and deterioration of water quality. It also violates environmental regulations, necessitating a wastewater treatment device.

[0003] In the prior art, the utility model patent with patent number CN202321503508.4 discloses a pre-prepared food production wastewater treatment system, in which a grid is set in the grid channel. After passing through the grid, the wastewater enters the regulating tank through the sewage pipe. Under the action of the regulating tank lifting pump, the wastewater is lifted to the flotation device. After the solid-liquid separation of the wastewater in the flotation device, the supernatant flows into the intermediate water tank by gravity. The wastewater in the intermediate water tank is lifted by the lifting pump to the hydrolysis acidification tank for degradation. After degradation, the wastewater enters the anoxic tank and the aerobic tank in turn for biochemical reactions. The effluent from the aerobic tank enters the secondary sedimentation tank through the sewage pipe for mud-water separation. The separated supernatant enters the coagulation sedimentation system through the pipe for further mud-water separation. After the supernatant meets the standards, it is discharged through the pipe. This pre-prepared food production wastewater treatment system has significant treatment effect and is easy to operate and manage. It is a system specifically used to treat pre-prepared food production wastewater. It not only ensures the reasonable feasibility of costs and operating management expenses, but also ensures that the effluent water quality is stable and meets the standards, while reducing pollution to the water ecological environment.

[0004] The above patent provides a system that can be used for the treatment of pre-prepared food wastewater. The system can gradually clean the impurities in the wastewater through multiple treatments; however, the device is a screen that can separate solid impurities in the sewage pipe. Although the screen can separate the solid impurities in the wastewater, each time the screen is cleaned, the device needs to be stopped before the inside of the screen can be cleaned. Not only is the cleaning troublesome, but when too much solid waste accumulates on the screen, it will cause internal blockage; further improvement is needed. Utility Model Content

[0024] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0025] like Figure 2-Figure 5 As shown, a system for intelligently treating wastewater from the production of prepared dishes comprises a sewage pool 2 and a water pump 8, and also comprises a filter device 1. A water outlet 102 is provided at the bottom of the filter device 1, and a drain surface 103 is provided on the side of the water outlet. The water outlet 102 at the lower end of the filter device 1 is located on the sewage pool 2. By providing the sewage pool 2 at the lower end of the filter device 1, the sewage discharged from the prepared dishes can be filtered by the filter device 1 first, and then collected in the sewage pool 2, so that the fixed garbage in the sewage can be filtered first. In addition, a connecting bolt 11 is included. The lower end surface of the water outlet 102 of the filter device 1 is provided with a first mounting edge 101, and the upper end of the sewage pool 2 is provided with a second mounting edge 201. The first mounting edge 101 and the second mounting edge 201 are connected by the connecting bolt 11. The filter device 1 and the sewage pool 2 are installed by the connecting bolt 11, which can facilitate the subsequent disassembly and installation. A trash basket 13 is placed on the drain surface 103. A placement rack 107 is provided inside the filter device 1 above the drain surface 103, and the trash basket 13 is mounted on the placement rack 107. The trash basket 13 includes a water filter hole 1301 and a handle 1302.

The side of the trash basket 13 away from the separation filter conveyor belt 12 is provided with a handle 1302. A separation filter conveyor belt 12 is tilted and rotated in the filter device 1. The separation filter conveyor belt 12 includes a mesh 1201. A plurality of meshes 1201 are provided in a matrix on the belt surface of the separation filter conveyor belt 12. The lower end of the separation filter conveyor belt 12 is provided on the water outlet 102, and the upper end is provided above the trash basket 13. Inside the filter device 1, a support shaft 104 is rotatably mounted above the water outlet 102. A power shaft 105 is rotatably mounted above the trash basket 13. One end of the power shaft 105 extends through the side of the filter device 1 and is equipped with a motor 106. The separation and filtration conveyor belt 12 is supported by the support shaft 104 and the power shaft 105. The motor 106 drives the power shaft 105 to rotate, which in turn drives the separation and filtration conveyor belt 12. As sewage passes through the separation and filtration conveyor belt 12, it separates the sewage and solid waste. The solid waste is then transported to the trash basket 13 via the separation and filtration conveyor belt 12, preventing clogging of the filter device 1.

[0026] like Figure 1As shown, the sewage tank 2 is connected to the sides of the regulating tank 3, which is connected in sequence by a pump 8. The outlet of the filter press 7 is connected to the regulating tank 3 via a pipeline. The secondary sedimentation tank 5 is connected to a flocculant tank 9 and a dosing tank 10. After being neutralized in the regulating tank 3, the sewage enters the primary sedimentation tank 4 and the secondary sedimentation tank 5 for sedimentation, precipitating impurities. Simultaneously, the flocculant tank 9 and the dosing tank 10 connected to the secondary sedimentation tank 5 add flocculants and chemicals to the secondary sedimentation tank 5, further flocculating and settling impurities in the sewage. The flotation device 6 then removes any remaining fine impurities and oil. This multi-stage cleaning process effectively removes impurities from the sewage. The filter press 7 then compresses and separates the sludge in the sewage, and the purified water is discharged. The regulating tank 3 includes a water level detector 301, which is installed inside the regulating tank 3 to monitor the water level. The water level detector 301 provided in the regulating tank 3 can detect the water level inside the regulating tank 3, preventing the sewage in the regulating tank 3 from overflowing. At the same time, the regulating tank 3 can neutralize different sewage, preventing the different sewage quality from damaging other equipment. The flotation device 6 includes an air pump 601. The air outlet of the air pump 601 is provided with a main air pipe 602. The main air pipe 602 is arranged around the bottom end of the side of the flotation device 6.

[0029] The working principle of the present invention is as follows: the sewage from pre-prepared dishes is transported to the separation and filtering conveyor belt 12 in the filtering device 1 through a pipeline. The rotating separation and filtering conveyor belt 12 can separate the sewage and solid waste, and transport them to the garbage basket 13 through the separation and filtering conveyor belt 12; the filtered sewage will enter the sewage pool 2, and enter the regulating tank 3, the primary sedimentation tank 4, the secondary sedimentation tank 5, the flotation device 6 and the filter press 7 in sequence through the water pump 8 for gradual cleaning, thereby realizing the purification of the sewage. At the same time, the regulating tank 3 can detect the water level in the regulating tank 3 through the water level detector 301 to prevent it from overflowing.
