Description

Technical Field

[0001] The utility model relates to the technical field of rural sewage treatment, in particular to a resource utilization device for rural domestic sewage treatment. Background Art

[0002] The main method of domestic sewage treatment in rural areas is small three-chamber septic tanks, which mainly treat black water such as feces discharged from the bathroom, while grey water from kitchens, showers, etc. is generally discharged directly without treatment. At this stage, traditional anaerobic + artificial wetland technology is widely promoted. When treating rural domestic sewage, it has disadvantages such as large footprint, high construction cost, short service life, and inconvenient sewage resource utilization, and has great limitations.

[0003] However, the existing artificial wetland process treatment has exposed the defect of occupying a large area in rural domestic sewage. At the same time, the traditional rural decentralized sewage treatment process often only focuses on whether the sewage water quality meets the standards, but ignores the importance of rural sewage reuse. Even if the relevant reuse function is partially considered, it does not pay attention to the convenience and energy-saving effect of sewage resource utilization. Therefore, it does not meet the existing needs. In this regard, we propose a resource utilization device for rural domestic sewage treatment. Utility Model Content

[0027] See also Figure 1A control cabinet 17 is provided on one side above the pool body 20. The control cabinet 17 is electrically connected to the reuse water pump 13 through a water pump control line 16. The control cabinet 17 can control the reuse water pump 13 through the water pump control line 16.

[0028] See also Figure 4 An air pump 18 is provided on one side of the control cabinet 17, and an aeration device 11 is provided at the lower end of the sewage treatment chamber 1. The aeration device 11 and the air pump 18 are connected through an aeration connecting pipe 12. The microorganisms in the sewage treatment filler 10 can be aerated through the aeration connecting pipe 12 and the aeration device 11. The sewage treatment filler 10 is an artificial filler, preferably a suspended filler;

[0029] See also Figure 1 A J-shaped connecting pipe 7 is installed on one side of the middle partition 3 located at the sewage treatment chamber 1. The J-shaped connecting pipe can effectively allow the scum, foam and solid sediment in the sewage treatment chamber 1 to enter the water storage chamber 2, thereby ensuring the water quality of the effluent;

[0030] See also Figure 1 and Figure 4 A reuse sprinkler head 15 is disposed outside the pool body 20, and the reuse sprinkler head 15 is connected to the reuse water pump 13 through a reuse water pipe 14. Farmers use the reuse sprinkler head 15 to water the surrounding vegetable fields, completing the tail water resource utilization process;

[0031] See also Figure 3 An exhaust pipe 8 is installed at the upper end of the middle partition 3. The exhaust pipe 8 is arranged to prevent excessive gas inside the sewage treatment chamber 1 during aeration;

[0033] Working principle: When in use, rural domestic sewage enters the tank body 20 through the water inlet pipe 6, and the sewage will first enter the interior of the sewage treatment chamber 1, and after the biochemical reaction of the microorganisms attached to the sewage treatment filler 10, it enters the water storage chamber 2. After the water inlet pipe 6 enters the sewage treatment chamber 1, it goes deep below the liquid surface, which can more effectively separate grease and avoid clogging of the sewage treatment filler 10. A J-shaped connecting pipe 7 is installed on one side of the middle partition 3 of the tank body 20. The lower end of the J-shaped connecting pipe 7 is immersed in the middle of the liquid level of the sewage treatment chamber 1, and the upper end exceeds the top of the liquid surface of the sewage treatment chamber 1. The right end extends to the water storage chamber 2 through the middle partition 3. The J-shaped connecting pipe 7 can effectively allow the scum, foam and solid sediment in the sewage treatment chamber 1 to enter the water storage chamber 2, thereby ensuring the water quality of the effluent. A reuse water pump 13 and a reuse water pipe 14 are provided in the water storage chamber 2. When the tail water is not reused, the tail water that meets the treatment standards is directly discharged into the surrounding ditches from the outlet pipe 9. When the tail water is reused, open the control cabinet 17 The power switch of the control cabinet 17 is turned on, and the energy storage battery integrated in the control cabinet 17 controls the reuse water pump 13 to start after being powered on through the water pump control line 16. The tail water in the water storage chamber 2 is pumped to the ground by the reuse water pipe 14. Farmers use the reuse sprinkler head 15 to water the surrounding vegetable fields to complete the tail water resource utilization process. The solar panel 19 is arranged in sunny places such as the roof, side wall, and open space. The solar panel 19 charges the energy storage battery after generating electricity. When the control cabinet 17 controls the air pump 18 to be powered on, compressed ventilation is aerated for the microorganisms in the sewage treatment filler 10 through the aeration connecting pipe 12 and the aeration device 11. When the aeration device 11 is working, excess gas enters the water storage chamber 2 through the exhaust pipe 8, and then can be discharged from the pool body 20 through the outlet pipe 9. When the sewage treatment chamber 1 needs to be repaired or the scum is cleared, it can be completed by opening the sewage treatment chamber inspection port 4. When the water storage chamber 2 needs to check the water quality or overhaul, it can be completed by opening the water storage chamber inspection port 5, which is convenient to use.
