Description

Technical Field

[0001] This utility model relates to the field of fecal sewage treatment technology, specifically to a fecal sewage fermentation reaction treatment tank. Background Art

[0002] Wastewater refers to the washing water excreted by residents in their daily lives, including feces and urine. In other countries, wastewater is also called black water. Another concept opposite to black water is grey water. There are two definitions of black water in other countries: one is domestic sewage containing fecal matter; the other is toilet sewage, including flushing water and feces.

[0003] If sewage is not properly treated and is stored and accumulated over a long period of time, especially in areas without sewage pipe networks, sewage is basically not effectively treated. It either accumulates in septic tanks or is discharged in the open, which can easily cause many adverse effects (such as gas poisoning, fire and explosion, and environmental pollution). This application proposes a technical solution to address this problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 The fecal sewage fermentation reaction treatment tank in this embodiment includes a tank body 1, a tank structure 2, a primary fermentation box 9, a secondary fermentation box 10, and a comprehensive fermentation box 11. The tank body 1 is equipped with a sewage control component and a heat preservation and conveying component.

[0026] It should be noted that both the primary fermentation tank 9 and the secondary fermentation tank 10 are equipped with aeration devices, and the tank body 1 is connected to the solid-liquid separation equipment.

[0027] Example 1: Please refer to Figures 1 to 3 The sewage control assembly includes an exhaust pipe 5 fixedly installed on the top of the tank body 1, a motor 6 fixedly installed on the top of the tank body 1, a water pump shaft 18 provided at the output end of the motor 6, a first through hole opened on the top of the tank body 1, the output end of the motor 6 being connected to the water pump shaft 18 through the first through hole, and a sewage pump 19 fixedly connected to the bottom of the water pump shaft 18.

[0028] The output end of the sewage pump 19 is fixedly connected to the water outlet pipe 20. The top of the water outlet pipe 20 is fixedly connected to the first mounting flange 17. The top of the first mounting flange 17 is fixedly connected to the organic fertilizer discharge pipe 15. The side of the organic fertilizer discharge pipe 15 is fixedly connected to the return pipe 16. The top of the tank body 1 is provided with a second through hole. The return pipe 16 extends into the interior of the integrated fermentation tank 11 through the second through hole.

[0029] A control box 8 is installed on the outside of the tank body 1. A liquid level gauge mounting flange 7 is fixedly installed on the top of the tank body 1. Solenoid valves 21 are fixedly connected to the outside of the organic fertilizer discharge pipe 15 and the return pipe 16 to facilitate control of the liquid discharge time and flow rate.

[0030] The tank structure 2 consists of a main beam 25, a support beam 26, a tightening component 27, an insertion hole 28, and a reinforcing corner piece 29. The top of the main beam 25 is provided with an insertion hole 28, and the top and bottom of the support beam 26 are both fixedly installed with tightening components 27. The top of the main beam 25 and the outer side of the support beam 26 are provided with connection holes for installing the reinforcing corner piece 29. The tank structure 2 makes the tank body 1 more stable.

[0031] It should be noted that the system can be automated, requiring almost no human intervention in the process. In the treatment of fecal sewage, it can render the sewage harmless and, through the action of microorganisms, turn the sewage into liquid organic fertilizer, thereby achieving full resource utilization of waste and improving the efficiency and quality of fecal sewage treatment.

[0032] Example 2: Please refer to Figures 4 to 6 Based on Embodiment 1, a heat-insulating conveying assembly is also provided on the tank body 1. The heat-insulating conveying assembly includes a corrosion-resistant partition 12 fixedly installed inside the tank body 1. The corrosion-resistant partition 12 is composed of a first corrosion-resistant plate 22, an electric heating plate 23, and a second corrosion-resistant plate 24. The electric heating plate 23 is installed and connected between the first corrosion-resistant plate 22 and the second corrosion-resistant plate 24. The electric heating plate 23 can heat and insulate the sewage liquid transmitted to the inside, thereby improving the reaction efficiency of sewage fermentation.

[0033] A deep overflow pipe 14 is provided on one side of the anti-corrosion partition 12. There are two anti-corrosion partitions 12 and four deep overflow pipes 14. The anti-corrosion partition 12 has an opening inside, and the deep overflow pipe 14 passes through the opening to penetrate the anti-corrosion partition 12.

[0034] The anti-corrosion partition 12 has a number of ventilation holes 13 inside, and a water inlet pipe 4 is fixedly installed on the top of the tank body 1. A fermentation reactor mounting flange 3 is provided on the top of the tank body 1.

[0035] It should be noted that the internal structure of the sewage fermentation reaction tank is interconnected, and the generated gas is discharged to the second and third stage purification fermentation reaction chambers through the vent 13, and finally discharged through the pipe. This ensures that the odor in the space is discharged and collected. At the same time, the sewage reaction environment inside the tank body 1 is closed, which can prevent odor from overflowing and reduce the leakage of harmful gases such as ammonia, hydrogen sulfide, and methyl mercaptan, which would seriously affect the air quality and improve the quality of the equipment.

[0036] The working principle of the above embodiment is:

[0037] During the construction of public toilets, a suitable underground space is reserved for the fermentation reaction tank for fecal sewage. After the foundation construction is completed, the tank body 1 frame and tank structure 2 are transported to the site for assembly. The tightening parts 27 at both ends of the support beam 26 are inserted into the insertion holes 28. At the same time, the connection is reinforced by the reinforcing corner pieces 29. The tank is then assembled and sealed with glue. After completion, the aeration device, liquid level conduit, liquid level switch, exhaust pipe 5, sewage pump 19, air pump, etc. are installed in sequence. After all pipeline equipment is installed, the fecal sewage lifting pump is connected.

[0038] In use, fecal sewage is first poured into the primary fermentation tank 9 through the inlet pipe 4. Through the aeration device in the primary fermentation tank 9, combined with the action of microorganisms, the fecal sewage undergoes a preliminary fermentation reaction in the primary fermentation tank 9. After the liquid level in the primary fermentation tank 9 reaches a certain height, it is deeply guided into the secondary fermentation tank 10 through the deep overflow pipe 14 installed on the anti-corrosion partition 12 of the secondary fermentation tank 10. In the secondary fermentation tank 10, through the aeration device, combined with the action of microorganisms, the final aerobic fermentation is completed. Then, through the deep overflow pipe 14 installed on the anti-corrosion partition 12 of the comprehensive fermentation tank 11, it is deeply guided into the comprehensive fermentation tank 11 for comprehensive anaerobic fermentation.

[0039] After the liquid in the integrated fermentation tank 11 completes anaerobic fermentation and the liquid level reaches the set height, the built-in sewage pump 19 starts to work and transports the treated liquid out for collection through the water outlet pipe 20 and the organic fertilizer discharge pipe 15. It can be used as liquid organic fertilizer for planting and application. At the same time, the residual gas in the integrated fermentation tank 11 is discharged to the connected gas collection tank through the exhaust pipe 5.
