Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to a non-powered solar-powered rural sewage composite biological treatment device. Background Technology

[0002] With the rapid development of my country's rural economy and the improvement of farmers' living standards, water consumption and sewage discharge in rural areas have been increasing year by year. However, rural sewage is characterized by dispersed discharge, large fluctuations in water volume, complex water composition (containing organic matter, nitrogen and phosphorus compounds, pesticide residues, and small amounts of heavy metals), and great difficulty in collection and treatment. Currently, many rural areas lack a complete sewage collection and treatment system, and large amounts of untreated domestic sewage, livestock wastewater, and farmland runoff are directly discharged into surrounding water bodies, leading to eutrophication and water quality deterioration. This not only seriously pollutes the rural ecological environment but also threatens the drinking water safety and health of residents.

[0003] Based on the above, the inventors have discovered that traditional rural sewage treatment technologies, such as septic tanks and stabilization ponds, suffer from problems such as low treatment efficiency, large land area requirements, easy generation of foul odors, and significant susceptibility to climate. Furthermore, some small-scale centralized sewage treatment equipment often rely on the power grid for power supply, resulting in high operating costs and poor applicability to rural areas with unstable power grid coverage or underdeveloped economies. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a non-powered solar-powered rural sewage composite biological treatment device, aiming to achieve a more practical and valuable purpose. Utility Model Content

It can replace the traditional electric blower with the natural airflow formed by the combination of exhaust chimney, air inlet pipe and aeration pipe to achieve continuous aeration. By using solar energy to provide power and combining composite biological treatment technology, it can achieve efficient, low-consumption and stable treatment of rural sewage, effectively solving the problems of low treatment efficiency, large land area, easy generation of odor, significant influence of climate and poor applicability of traditional rural sewage treatment technology.

[0014] Furthermore, the other end of the treatment pool is fixed and connected to a water inlet port.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This plan is approved.

[0018] The natural airflow circulation system, formed by the combination of an exhaust chimney, air inlet pipe, and aeration pipe, cleverly utilizes the thermal pressure effect created by the "greenhouse effect" and the "chimney effect" to achieve non-powered aeration. Specifically, a transparent plate allows sunlight to pass through and shine onto the heat-absorbing plate on the inner wall of the treatment tank. After absorbing solar energy, the heat-absorbing plate transfers heat to the air inside the treatment tank, raising the air temperature and reducing its density. At the same time, the black cylindrical exhaust chimney absorbs more solar radiation, further heating its internal air and creating stronger thermal buoyancy. The hot air rises and exits along the exhaust chimney, creating negative pressure inside the treatment tank, which then naturally draws in fresh air from the outside through the air inlet pipe that extends outside the tank and bends upwards. The fresh air enters multiple aeration pipes through the air inlet pipes and is released into the wastewater in the form of tiny bubbles from the micropores of the aeration pipes. This increases the dissolved oxygen content in the wastewater, providing sufficient oxygen for the growth and metabolism of aerobic microorganisms, effectively promoting the degradation of organic matter in the wastewater, replacing traditional electric blowers, and significantly reducing operating energy consumption.

[0019] (2) In this scheme, solar energy can be converted into electrical energy by installing solar panels on both sides of the device, and stored in a battery through a controller to provide power for the drive motor. The drive motor drives the rotating shaft to rotate, which in turn drives the biological rotating disc to rotate. When the surface of the biological rotating disc is submerged in sewage, the biofilm attached to the disc will adsorb and degrade pollutants in the sewage; when the disc rotates out of the water, it comes into contact with the air, absorbs oxygen, and restores the activity of the biofilm. This alternating wet and dry environment is conducive to the renewal of the biofilm and the improvement of metabolic efficiency. In synergy with the non-powered aeration system, a composite biological treatment mechanism is formed, which further improves the treatment efficiency of complex pollutants such as organic matter, nitrogen and phosphorus compounds in rural sewage.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Example:

[0040] Please see Figures 1-4 A non-powered solar-powered rural sewage composite biological treatment device includes a treatment tank 1, a heat-absorbing plate 2 fixedly connected to the inner wall of the treatment tank 1, a transparent plate 3 fixedly connected to the top of the treatment tank 1, a mounting base 4 fixedly connected to the top of the transparent plate 3, an exhaust chimney 5 fixedly installed on the top of the mounting base 4, an air inlet pipe 6 provided inside the treatment tank 1, multiple aeration pipes 7 fixedly connected to the top of the air inlet pipe 6, solar panels 8 installed on both sides of the treatment tank 1, multiple rotating shafts 9 rotatably connected between the inner walls of both sides of the treatment tank 1, and multiple biological rotating discs 10 fixedly installed on the outer periphery of the rotating shafts 9.

[0041] See Figure 2 Multiple drive motors 11 are fixedly installed on one side of the treatment pool 1. One end of the rotating shaft 9 extends to the outside of the treatment pool 1 and is connected to the output shaft of the corresponding drive motor 11 via a coupling.

[0042] See Figure 2 A storage battery 12 is fixedly installed on one side of the treatment pool 1. One end of the storage battery 12 is electrically connected to the solar panel 8 through a controller, and the other end of the storage battery 12 is electrically connected to the drive motor 11 through a wire.

[0043] See Figure 1 The transparent panel 3 is made of either PC board or glass.

[0044] See Figure 1 The bottom of the exhaust chimney 5 is connected to the interior of the treatment tank 1, and the exhaust chimney 5 has a black cylindrical structure.

[0045] See Figure 1 and Figure 2 One end of the air intake pipe 6 extends to the outside of one end of the treatment tank 1 and bends upward.

[0046] See Figure 1 The other end of the treatment tank 1 is fixed and connected to a water inlet port 13.

[0047] Working Principle: In operation, the rural wastewater to be treated is first introduced into the treatment tank 1 through the inlet port 13. Under sunlight, the transparent plate 3 allows sunlight to pass through and irradiate the heat-absorbing plate 2 on the inner wall of the treatment tank 1. The heat-absorbing plate 2 absorbs solar energy and transfers heat to the air inside the treatment tank 1, increasing the air temperature and decreasing its density. Simultaneously, the black cylindrical exhaust chimney 5 absorbs solar radiation and further heats its internal air, creating stronger thermal buoyancy. The hot air rises and is discharged along the exhaust chimney 5, creating negative pressure inside the treatment tank 1. At this time, fresh outside air is naturally drawn in through the air inlet pipe 6, which extends to the outside of the treatment tank 1 and bends upwards. The air enters multiple aeration pipes 7 through the air inlet pipe 6 and is released into the wastewater as tiny bubbles from the micropores of the aeration pipes 7, increasing the dissolved oxygen content in the wastewater. Meanwhile, the solar panels 8 on both sides of the treatment tank 1 convert solar energy into electrical energy, which is stored in the battery 12 via a controller. The battery 12 provides power to the drive motor 11. The drive motor 11 drives the rotating shaft 9 to rotate, which in turn drives the biological rotating disc 10 to rotate. When the surface of the biological rotating disc 10 is submerged in sewage, the biofilm attached to the disc adsorbs and degrades pollutants in the sewage; when the disc rotates out of the water, it comes into contact with the air, absorbs oxygen, and restores the activity of the biofilm. This cycle continues, achieving continuous purification of sewage.
