Description
Technical Field
[0001] The present invention belongs to the technical field of septic tanks, and specifically refers to a composite microbial septic tank. Background Art
[0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, as an important facility for the preliminary treatment of domestic sewage, the performance and effect of septic tanks have received increasing attention. Traditional septic tanks usually adopt a single tank structure, and sewage and sludge undergo natural sedimentation and anaerobic fermentation decomposition in the tank. However, there are many drawbacks to this traditional septic tank:
[0003] 1. Low decomposition efficiency: Due to the lack of effective microbial assistance, the organic matter in sewage and sludge is only slowly decomposed by natural anaerobic microorganisms, with a slow decomposition rate. It is difficult to fully degrade the pollutants in sewage in a short time, resulting in limited treatment capacity of the septic tank, a long residence time of sewage in the tank, and affecting the operation efficiency of the subsequent sewage treatment system.
[0004] 2. Poor deodorization effect: During the anaerobic fermentation process of traditional septic tanks, a large amount of harmful gases with pungent odors such as hydrogen sulfide and ammonia are generated. These gases not only cause serious pollution to the living environment of surrounding residents, affect the physical and mental health of residents, but also may corrode the buildings and facilities around the septic tank.
[0005] Although there are also some improved septic tanks in the prior art, such as increasing the number of partition layers of the tank body and setting stirring devices to improve the treatment effect, these improvement measures still have certain limitations and cannot fundamentally solve the problems of slow decomposition and poor deodorization effect of septic tanks. Summary of the Invention
[0006] In view of the above situation, to overcome the defects of the prior art, the present invention provides a composite microbial septic tank, effectively solving the problems of slow decomposition and poor deodorization effect of septic tanks.
[0007] To achieve the above functions, the technical solution adopted by the present invention is as follows: A composite microbial septic tank includes a tank body. Two partition plates are provided inside the tank body, and the partition plates divide the tank body into a first tank, a second tank, and a third tank. A microbial inoculant adding mechanism is provided above the first tank, an inlet is provided on one side of the first tank, an outlet is provided on one side of the third tank, and diversion pipes are provided on the partition plates to communicate with adjacent tank bodies respectively;
[0008] The microbial inoculant adding mechanism includes a discharge pipe, a chemical addition tank, and connecting columns. The discharge pipe penetrates through the top of the tank body and communicates with the first tank. The chemical addition tank is fixedly connected to the discharge pipe. Four groups of the connecting columns penetrate through the top wall of the tank body and are slidably arranged. A connecting bottom plate is fixed to the bottom of the connecting column. The top end of the connecting column extends out of the top of the tank body and is fixed with a connecting top plate. A spring is sleeved outside the connecting column, and the spring is fixed between the bottom of the connecting top plate and the top of the tank body. A sleeve block is fixed on the connecting column, a support rod is fixed on the sleeve block, and a sealing block is fixed on the support rod. The sealing block is hermetically abutted against the bottom of the discharge pipe.
[0009] Preferably, a connecting rod located inside the discharge pipe is fixed to the top end of the sealing block, and a plurality of groups of push plates arranged in a staggered array are provided on the connecting rod.
[0010] Preferably, a conical flow guiding plate is provided at the center of the connecting bottom plate below the water inlet.
[0011] Preferably, a support plate is fixed to the inner wall of the first tank, a receiving frame is provided at the bottom of the support plate below the water inlet, and a water leakage hole is provided at the bottom of the receiving frame.
[0012] Preferably, the receiving frame adopts a stainless steel mesh structure, the aperture of the water leakage hole is 5 - 8 mm, and the hole pitch is 10 - 15 mm.
[0013] Preferably, the chemical addition tank is filled with a composite microbial inoculant, which contains various components such as cellulase, amylase, protease, lipase, glucose, xanthan gum, locust bean ester, beef extract, etc.
[0014] Preferably, inspection openings are provided at the tops of the first tank, the second tank, and the third tank, and covers are sealed in the inspection openings.
[0015] Preferably, an L-shaped air outlet pipe penetrating through the connecting top plate is communicated with the top of the tank body.
[0016] The beneficial effects of the present invention adopting the above structure are as follows:
[0017] 1. By arranging a microbial inoculant adding mechanism above the first tank in the present invention, when sewage enters from the water inlet, the inoculant adding mechanism is triggered to add the microbial inoculant to the sewage in a timely manner. These microbial inoculants can quickly reproduce in the sewage, accelerate the decomposition rate of organic matters in the sewage and sludge, significantly improve the treatment efficiency of the septic tank, shorten the residence time of the sewage in the tank, enhance the overall sewage treatment capacity, and the efficient decomposition effect of the inoculant can reduce the accumulation of sludge and impurities, reduce the risk of blockage, reduce the cleaning frequency of the septic tank, and reduce the maintenance cost.
[0018] 2. In the process of decomposing organic matter, microbial agents can effectively inhibit the production of harmful gases and decompose the already produced odorous gases such as hydrogen sulfide and ammonia, significantly improving the air quality around the septic tank, reducing pollution to the living environment of surrounding residents, and reducing the corrosion of harmful gases to surrounding buildings and facilities.
[0019] 3. The linkage mechanism composed of connecting columns, springs, sleeves, support rods and sealing blocks cleverly utilizes the gravity when sewage enters, realizes the automatic addition of microbial agents, does not require additional power devices, reduces equipment costs and energy consumption, and has a simple structure and stable and reliable operation.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] As Figures 1-6 shown, a composite microbial septic tank proposed by the present invention includes a tank body 1. There are two groups of partition plates 2 arranged in the tank body 1. The partition plates 2 divide the tank body 1 into a first tank 3, a second tank 4, and a third tank 5. A microbial agent adding mechanism 8 is arranged above the first tank 3. An inlet 6 is arranged on one side of the first tank 3. An outlet 7 is arranged on one side of the third tank 5. A diversion pipe 26 is arranged on the partition plate 2 to communicate with adjacent tank bodies 1 respectively. Inspection openings 24 are arranged at the tops of the first tank 3, the second tank 4, and the third tank 5. A cover plate 25 is sealed in the inspection opening 24;
[0030] As Figure 4 、 6 shown, the microbial agent adding mechanism 8 includes a discharge pipe 9, a medicine adding bin 10, and a connecting column 11. The discharge pipe 9 penetrates through the top of the tank body 1 and communicates with the first tank 3. The medicine adding bin 10 is fixedly connected to the discharge pipe 9. Four groups of connecting columns 11 penetrate through the top wall of the tank body 1 and are slidably arranged. A connecting bottom plate 12 is fixed at the bottom of the connecting column 11. The top end of the connecting column 11 extends out of the top of the tank body 1 and is fixed with a connecting top plate 13. A conical diversion plate 20 is arranged below the center of the connecting bottom plate 12 and below the inlet 6 to prevent materials from accumulating on the connecting bottom plate 12. A spring 14 is sleeved outside the connecting column 11. The spring 14 is fixed between the bottom of the connecting top plate 13 and the top of the tank body 1. The spring 14 is a compression spring 14 and is in a compressed state under normal conditions, providing an upward elastic force for the connecting column 11. A sleeve block 15 is fixed on the connecting column 11. A support rod 16 is fixed on the sleeve block 15. A sealing block 17 is fixed on the support rod 16, and the sealing block 17 seals and abuts against the bottom of the discharge pipe 9.
[0031] A support plate 21 is fixed to the inner wall of the first tank 3. A receiving frame 22 is provided on the support plate 21 at the bottom of the water inlet 6. A leakage hole 23 is provided at the bottom of the receiving frame 22, which can effectively intercept impurities such as paper towels that are not easily decomposed and prevent these impurities from entering the septic tank and causing blockage. The receiving frame 22 is made of a stainless steel mesh structure. The aperture of the leakage hole 23 is 5 - 8 mm, and the hole spacing is 10 - 15 mm.
[0032] As Figure 6 shown, a connecting rod 18 located inside the discharge pipe 9 is fixed to the top end of the sealing block 17. Multiple groups of push plates 19 arranged in a staggered array are provided on the connecting rod 18. Among them, when sewage enters the first tank 3 through the water inlet 6 and impacts the connecting bottom plate 12, the connecting column 11 drives the sealing block 17 to move downward, opening the discharge pipe 9 and releasing the microbial agent. At the same time, the push plate 19 moves downward to dredge the discharge pipe 9.
[0033] An L-shaped air outlet pipe 27 is connected to the top of the tank body 1 and penetrates through the connecting top plate 13. During the process of microbial decomposition of organic matter in the septic tank, a large amount of gas will be generated, such as carbon dioxide, methane, etc. The L-shaped air outlet pipe 27 can discharge these gases in time, prevent the pressure in the tank from being too high, avoid damage to the structure of the tank body 1, and ensure the safe and stable operation of the septic tank.
[0034] The dosing tank 10 is filled with a composite microbial agent, which contains various components such as cellulase, amylase, protease, lipase, glucose, xanthan gum, locust bean gum, beef extract, etc. It can specifically and rapidly decompose the corresponding organic matter in the septic tank. For example, cellulase decomposes fiber substances, amylase decomposes starch substances, and protease decomposes protein substances, accelerating the degradation of feces and sundries, improving the treatment efficiency, and reducing sludge accumulation; it can effectively act in the complex environment of the septic tank, accelerate the decomposition process, has a wide operating temperature range, and is still highly efficient at 45°C. It can flexibly adjust the pH value, adapt to the water quality differences of septic tanks in different regions and different usage situations, and stably exert the functions of decomposition and deodorization.
[0035] During specific use, when domestic sewage enters the septic tank from the water inlet 6, the sewage first falls on the connecting bottom plate 12. As the sewage continuously enters, the gravity received by the connecting bottom plate 12 gradually increases. When the gravity is greater than the elastic force of the spring 14, the connecting bottom plate 12 drives the connecting column 11 to move downward. During the process of the connecting column 11 moving downward, it drives the sleeve block 15, the support rod 16, and the sealing block 17 to move downward together. The sealing block 17 moves downward to open the discharge pipe 9, and the microbial agent in the dosing tank 10 falls into the sewage in the first tank 3 under the action of gravity; at the same time, the sealing block 17 drives the connecting rod 18 and the push plate 19 to move downward. The push plate 19 moves in a staggered manner in the discharge pipe 9, which can effectively push away the blocky microbial agent or impurities that may block the discharge pipe 9, ensuring the smooth discharge of the microbial agent;
[0036] The sewage is fully mixed with the microbial inoculant in the first tank 3. After preliminary decomposition treatment, it flows into the second tank 4 through the diversion pipe 26 on the partition plate 2, continues the decomposition treatment in the second tank 4, and finally flows into the third tank 5. The sewage after three-stage treatment is discharged from the water outlet 7 and enters the subsequent sewage treatment system;
[0037] When no more sewage enters the water inlet 6, the gravity borne by the connecting bottom plate 12 decreases. Under the elastic force of the spring 14, the connecting column 11 drives the connecting bottom plate 12, the sleeve block 15, the support rod 16 and the sealing block 17 to move upward, and the sealing block 17 reseals the discharge pipe 9, waiting for the next water inlet to trigger the addition of the inoculant;
[0038] A temperature controller can also be added to the dosing tank 10 to ensure the adjustment of the activity of the inoculant. The composite microbial inoculant filled in the dosing tank 10 can specifically and rapidly decompose the corresponding organic matter in the septic tank, accelerate the decomposition process, adapt to the water quality differences of septic tanks in different regions and different usage situations, stably exert the functions of decomposition and deodorization. When in use, there is no need to move the septic tank, it can deodorize within 24 hours, be dredged in 2 - 4 weeks, does not affect the normal use of the septic tank, reduces operation trouble and costs, saves manpower and material resources, can effectively solve the problems of septic tank blockage and odor, dredge the pipeline, eliminate the pungent and unpleasant smell, improve the surrounding environment, ensure the living comfort and health of residents, and also reduce environmental pollution.
[0039] The above describes the present invention and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present invention. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, creatively design a structural manner and an embodiment similar to the technical solution, they shall fall within the protection scope of the present invention.
