Description

Technical Field

[0001] This application relates to the field of service area wastewater treatment, and in particular to a thermal insulation system for wastewater treatment facilities in high-altitude and cold-weather highway service areas. Background Technology

[0002] With the continuous expansion of the highway network, highway service areas, as indispensable facilities along highways, provide services such as rest, dining, refueling, and repair for passing vehicles and drivers. However, highway service areas generate a large amount of wastewater during operation, including domestic sewage, catering wastewater, and car wash wastewater. If this wastewater is discharged directly without treatment, it will have a serious impact on the surrounding environment. Therefore, wastewater treatment in highway service areas has become an urgent problem to be solved. More and more highway service area managers are beginning to pay attention to wastewater treatment and seeking professional wastewater treatment solutions to ensure the normal operation of service areas and environmental protection.

[0003] Wastewater from high-altitude and cold-climate highway service areas mainly originates from domestic sewage, car wash wastewater, highway flushing wastewater, and road construction wastewater. For areas requiring compliant wastewater discharge, real-time quantitative PCR and DGGE gene regulation methods are employed to screen and acclimate low-temperature resistant genes and functional bacteria in the core treatment unit of the biofilter. Through simulation experiments, reaction conditions under aerobic conditions are optimized, controlling microorganisms to endogenous respiration. This adapts them to low-oxygen conditions while reducing the energy consumption of aeration equipment. By selectively enriching and acclimatizing highly efficient microorganisms and controlling reaction conditions under aerobic conditions, wastewater treatment in high-altitude and cold-climate highway service areas achieves better treatment results, lower costs, and easier maintenance.

[0004] Service area wastewater mainly includes oil removal and biological media wastewater treatment. Considering the insulation measures throughout the entire process of treatment and discharge in functional tanks, a heat preservation and heating technology for wastewater treatment under low-temperature conditions in service areas is proposed to achieve a more economical biochemical treatment effect. Therefore, a heat preservation system for wastewater treatment facilities in high-altitude and cold-climate highway service areas is needed. An insulation layer can be installed on the surface of the wastewater treatment tank in high-altitude and cold-climate highway service areas. The insulation layer isolates the heat exchange between the tank and the outside world, thereby reducing the impact of low external temperatures on the temperature in the wastewater treatment tank, and thus improving the economy and treatment effect of the biological media wastewater treatment tank. Utility Model Content

By installing an insulation layer on the surface of the sewage treatment tank in the highway service area in high-altitude and cold-climate regions, the insulation layer isolates the tank from the outside environment, thereby reducing the impact of low external temperatures on the temperature inside the sewage treatment tank, and thus improving the economy and treatment effect of the biological media sewage treatment tank, thereby solving the problems mentioned in the background art.

[0006] This application provides a thermal insulation system for sewage treatment facilities in high-altitude and cold-weather highway service areas, employing the following technical solution: A thermal insulation system for sewage treatment facilities in high-altitude and cold-weather highway service areas includes an insulation layer: A hoop is wound around the surface of the insulation layer; a frame box and a rack are fixedly connected to both ends of the hoop; a rectangular box is fixedly connected to the bottom of the frame box by bolts; a rotating rod is rotatably connected to the inner wall of the frame box; a gear is fixedly connected to the surface of the rotating rod; a ratchet is fixedly connected to the surface of the rotating rod; a rectangular opening is formed on the surface of the rectangular box; a locking rod is rotatably connected to the inner wall of the rectangular opening via a rotating shaft; a spring is fixedly connected between the locking rod and the inner wall of the rectangular box; a biological media filter tank is provided on the surface of the insulation layer; a filter membrane layer is provided inside the cavity of the biological media filter tank; an aeration pipe is fixedly installed on the inner wall of the biological media filter tank; an aeration pump is fixedly installed on the top of the biological media filter tank by bolts; and the top end of the aeration pipe is connected to the air outlet pipe of the aeration pump.

This achieves the goal of setting an insulation layer on the surface of sewage treatment tanks in highway service areas in high-altitude and cold regions. The insulation layer isolates the tank from the outside environment, thereby reducing the impact of low external temperatures on the temperature in the sewage treatment tank, and thus improving the economy and treatment effect of the biological media sewage treatment tank.

[0008] Preferably, the bottom end of the rotating rod extends through to the bottom of the rectangular box and is fixedly connected to a handle block, and the rotating rod and the rectangular box are rotatably connected.

The insulation layer isolates the tank from the outside environment, reducing the impact of low external temperatures on the temperature inside the sewage treatment tank. This, in turn, improves the economy and treatment effect of the oil separation and removal biological media sewage treatment tank.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] Example 1:

[0026] Combination Figures 1-4 This application discloses an insulation system for a sewage treatment facility in a high-altitude highway service area, comprising an insulation layer 1. A hoop 2 is wound around the surface of the insulation layer 1. A frame box 3 and a rack 7 are fixedly connected to both ends of the hoop 2. A rectangular box 4 is fixedly connected to the bottom of the frame box 3 by bolts. A rotating rod 5 is rotatably connected to the inner wall of the frame box 3. A gear 6 and a ratchet 9 are fixedly connected to the surface of the rotating rod 5. A rectangular opening 10 is formed on the surface of the rectangular box 4. A locking rod 11 is rotatably connected to the inner wall of the rectangular opening 10 via a rotating shaft. A spring 12 is fixedly connected between the locking rod 11 and the inner wall of the rectangular box 4. A biological media filter tank 13 is provided on the surface of the insulation layer 1, and a filter membrane layer 14 is provided inside the biological media filter tank 13. The biological media filter tank 13 has a filter membrane layer 14 in its inner cavity, an aeration pipe 15 is fixedly installed on the inner wall of the biological media filter tank 13, and an aeration pump is fixedly installed on the top of the biological media filter tank 13 by bolts. The top end of the aeration pipe 15 is connected to the air outlet pipe of the aeration pump.

[0027] Example 2:

[0028] Combination Figures 1-4 The bottom end of the rotating rod 5 extends through to the bottom of the rectangular box 4 and is fixedly connected to the handle block 8. The rotating rod 5 and the rectangular box 4 are rotatably connected. By setting the handle block 8, the force-bearing area of ​​the rotating rod 5 surface is increased, avoiding the situation of hand slippage when directly holding the rotating rod 5 to rotate, thereby improving the accuracy of operating the rotating rod 5. The gear 6 and the rack 7 mesh with each other. The end of the locking rod 11 extends into the inner cavity of the rectangular box 4 and is engaged with the ratchet 9. The heat insulation layer 1 is a perlite heat insulation board layer, the hoop 2 is a stainless steel hoop, the surface of the biological media filter pool 13 is connected to the inlet pipe 16 and the outlet pipe 17, and the filter membrane layer 14 is a multi-media biological filter membrane layer.

[0029] Working Principle: In use, the user wraps the insulation layer 1 around the surface of the biological media filter tank 13, then engages the rack 7 with the gear 6. Next, rotating the rotating rod 5 drives the gear 6 to rotate, which in turn drives the clamp 2 to tighten via the rack 7. This tightens the frame 3 and the rack 7, thus securing the insulation layer 1 to the surface of the biological media filter tank 13. Furthermore, the spring 12 and the locking rod 11 work together to lock the ratchet 9 in the opposite direction, allowing the ratchet 9 to lock the rotation of the gear 6 in one direction via the rotating rod 5. This ensures the relative stability of the position between the gear 6 and the rack 7, preventing the clamp 2 from loosening. During this process, wastewater is introduced into the biological media filter tank 13 through the inlet pipe 16, and after filtration through the filter membrane layer 14, it is discharged through the outlet pipe 17. Furthermore, the aeration pipe 15 ensures the oxygen requirements of the biological media within the biological media filtration tank 13. It should be noted that the filter membrane layer 14 is a multi-media biological filter membrane layer, a type of filtration layer used in water treatment that combines multi-media filtration and biological treatment technologies. This type of filter membrane layer is typically composed of various filter media of different materials and particle sizes. These filter media provide a growth carrier for microorganisms, thereby achieving the biodegradation of pollutants such as organic matter and ammonia nitrogen in the water. This is existing technology and will not be described in detail here. It enables the installation of an insulation layer on the surface of wastewater treatment tanks in highway service areas in high-altitude and cold regions. The insulation layer isolates the tank from the outside environment, reducing the impact of low external temperatures on the temperature within the wastewater treatment tank, thus improving the economy and treatment efficiency of the biological media wastewater treatment tank.

[0030] In summary, the insulation system for the wastewater treatment facility in this high-altitude and cold-climate highway service area, through the meshing of the rack 7 and gear 6, allows the frame 3 and rack 7 to be tightened, thereby causing the clamping bar 2 to tighten the insulation layer 1 onto the surface of the biological media filter tank 13. This achieves the goal of setting an insulation layer on the surface of the wastewater treatment tank in the highway service area in high-altitude and cold-climate regions, isolating the tank from the outside environment through the insulation layer, thereby reducing the impact of low external temperatures on the temperature in the wastewater treatment tank, and thus improving the economy and treatment effect of the biological media wastewater treatment tank.

[0031] Experiment 1: The purification effect of sewage treatment ponds in high-altitude and cold service areas on sewage treatment

[0032] This experiment was conducted at the Xili Expressway service area on the G214 highway in Qinghai Province. The main focus was on the purification effect of different wastewater treatment ponds in high-altitude and cold-climate service areas on wastewater treatment, specifically the impact of using a wastewater treatment pond without an insulation system versus the one with an insulation system described in this application. Wastewater containing pollutants at predetermined concentrations was passed through the aforementioned treatment ponds, and the pollutant content of the effluent samples after treatment was measured. Each experimental group was repeated three times, and the average value was taken. The water samples were collected in August and November 2024.

[0033] Experimental Example 1

[0034] A purification experiment was conducted using the wastewater treatment tank combined with Examples 1-2.

[0035] Experiment Example 2

[0036] The traditional low-altitude service area pollution treatment pond was used in the experiment for high-altitude service areas without an insulation system.

[0037] Table 1. Purification effect of sewage treatment ponds in high-altitude and cold service areas on sewage treatment.

[0038]

[0039] Experimental Results: As shown in Table 1, comparative experiments conducted in August 2024 (summer) showed no significant difference in the purification effects of COD and SS concentrations in the wastewater treatment pond of a high-altitude service area with an insulation system compared to traditional low-altitude service area pollution treatment ponds. However, in November 2024 (winter), the purification effect of Experimental Example 1 was the best. Measurements of the influent and effluent concentrations of organic matter (COD and SS) showed that the purification rate of Experimental Example 1 with the insulation system was significantly higher than that of the treatment pond without an insulation system. Furthermore, in the temperature insulation performance experiment in November 2024, we found that under operating conditions, the time it took for the temperature to drop from 10°C to 0°C was 21.33% shorter for Experimental Example 1 than for Experimental Example 2. This indicates that the insulation system of this application has superior insulation performance and is more effective in improving purification efficiency.
