DETAILED DESCRIPTION

[0019] The embodiments described below are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 The present embodiment provides an energy-saving baffled agricultural sewage integrated machine, comprising a machine housing 1, wherein the interior of the machine housing 1 is sequentially divided into a primary sedimentation zone 10, an anaerobic zone 20, an anoxic zone 30, an aerobic zone 40, an artificial wetland zone 70 and a sedimentation zone 50 by a plurality of partitions 14, wherein the top of the primary sedimentation zone 10 is provided with an inlet 11, and the top side of the sedimentation zone 50 is provided with an outlet 13, wherein a composite filter layer 12 is provided inside the primary sedimentation zone 10, wherein the anaerobic zone 20 is provided with a plurality of arc-shaped upper baffles 21 with an arc of 1 / 2 arc to 1 arc, and a plurality of vertical lower baffles 22 spaced apart from the arc-shaped upper baffles 21, wherein the arc-shaped The bending direction of the upper baffle 21 is toward the side of the next vertical lower baffle 22 close to the anoxic zone 30, and the space between the partition 14 close to the primary sedimentation zone 10 and the first vertical lower baffle 22 and the space between the partition 14 close to the anoxic zone 30 and the last vertical lower baffle 22 are filled with anaerobic zone biological fillers 23, and the anoxic zone 30 and the aerobic zone 40 are filled with microbial fillers 60, the density of the microbial filler 60 in the anoxic zone 30 is less than the density of the microbial filler 60 in the aerobic zone 40, and an aeration device 41 is provided in the microbial filler 60 in the aerobic zone 40.

[0021] Preferably, the composite filter layer 12 comprises a pebble filter layer, a fine sand filter layer and an activated carbon filter layer stacked from top to bottom. First, the pebble filter layer can effectively remove large particle impurities and suspended matter in sewage, providing a basic guarantee for subsequent treatment; secondly, the fine sand filter layer further filters the fine particles and suspended matter in the water, improving the degree of water purification; finally, the activated carbon filter layer has excellent adsorption properties, which can remove organic matter, odor and pigment in the water, making the water cleaner and healthier. Such a composite filter layer 12 design not only effectively improves the water purification effect, but also reduces the maintenance cost of the equipment, extends the service life of the equipment, and provides an efficient and economical solution for agricultural sewage treatment. It should be noted that the composite filter layer 12 is configured as a plate-like structure and is provided with a handle, making installation and cleaning more convenient. Furthermore, an insertion port is provided on the side of the primary sedimentation area 10, and an installation port is provided in the inner recess of the side wall of the primary sedimentation area 10 opposite to the side wall of the insertion port. When in use, it is only necessary to insert the composite filter layer 12 of the plate-like structure into the insertion port, and then insert the other end of the composite filter layer 12 into the installation port. At the same time, rubber is provided at the contact position between the composite filter layer 12 and the insertion port to prevent water from overflowing. When the composite filter layer 12 needs to be cleaned, it is only necessary to pull out the composite filter layer 12 to conveniently carry out cleaning and maintenance, saving manpower and time costs.

[0022] It should be noted that in the present application, the curvature of the arc-shaped upper baffle 21 is 1 / 2 arc to 1 arc. First, this design ensures that the flow rate of sewage in the space between the adjacent arc-shaped upper baffle 21 and the vertical lower baffle 22 gradually decreases from the bottom to the top, thereby effectively preventing the problem of sludge loss. Specifically, the cross-sectional areas of the upper and lower parts of the space between the adjacent arc-shaped upper baffle 21 and the vertical lower baffle 22 are not equal. The sewage is gradually subjected to the increase of resistance during the flow process, resulting in a gradual decrease in the flow rate, so that the sludge in the sewage can be deposited at the bottom and will not be lost as the flow rate decreases, thereby ensuring the effective sedimentation and centralized removal of the sludge, and avoiding blockage and influence on the treatment system. Secondly, the arc of 1 / 2 arc to 1 arc increases the contact area, provides more space for the attachment and growth of microorganisms, is conducive to improving the biochemical degradation efficiency of sewage, and optimizes the water flow dynamics, so that the water flow forms an appropriate flow in the anaerobic zone 20, which is conducive to the uniform distribution of organic matter and the degradation of microorganisms. Thirdly, the arc of 1 / 2 arc to 1 arc can reduce the resistance of the water flow when it passes downward, reduce energy consumption, and improve the energy efficiency of the system. Further, the arc of the arc-shaped upper baffle 21 is 0.8 arcs, so that it can maintain a relatively stable and uniform water flow dynamics while satisfying the attachment and growth of microorganisms.

[0023] Preferably, the widest part of the interval between the arc-shaped upper baffle 21 and the vertical lower baffle 22 is no more than twice the narrowest part of the interval, so as to improve the dynamic characteristics of the water flow, produce a more uniform and stable flow state inside the equipment, help improve the mixing effect of the water flow, promote the contact and reaction between organic matter and microorganisms in the sewage, and improve the treatment efficiency.

[0024] Preferably, a plant rack 71 for planting aquatic plants is provided on the top of the artificial wetland area 70. The plant rack 71 provides space and support for the growth of aquatic plants, and provides an ecological niche for the wetland ecosystem. In the present application, the aquatic plants that can be planted on the plant rack 71 are aquatic plants such as pickerel grass, windmill grass, sedge grass, and yellow iris. The above-mentioned aquatic plants absorb nutrients and organic matter in the water through their roots, and release oxygen at the same time, which promotes the growth and metabolism of microorganisms in the water, helps to further purify the water quality, and at the same time reduces the organic matter in the sewage, thereby improving the environmental quality of the water body. It should be noted that a plant planting opening is provided at the top of the artificial wetland area 70 to facilitate the planting of plants in the artificial wetland area 70.

[0025] Preferably, a water quality detector is provided in the sedimentation area 50. First, the water quality detector can monitor various water quality indicators of the water body in the sedimentation area 50 in real time, such as suspended matter content, dissolved oxygen level, pH value, etc., so as to timely understand the operating status and water quality of the treatment system. Secondly, through the monitoring data of the water quality detector, the operator can adjust the operating parameters of the treatment equipment according to the real-time water quality information, such as adjusting the working intensity of the aeration device, controlling the flow rate of the water outlet pump, etc., to ensure that the treatment system always maintains the best operating state, thereby improving the treatment efficiency and water quality stability.

[0026] Preferably, the outlet 13 is connected to a water pump, and the outlet end of the water pump is provided with two branch pipes, and both branch pipes are provided with electronic valves. In the present application, one branch pipe is used for discharge, and the other branch pipe is connected to the inlet 11 provided at the top of the primary sedimentation area 10. When the water quality detector detects that the water quality is unqualified, the electronic valve of the branch pipe connected to the inlet 11 is opened, and the electronic valve of the other branch pipe is closed, and the working intensity of the aeration device is adjusted at the same time, so that the water is treated again; when the water quality detector detects that the water quality is qualified, the electronic valve of the branch pipe connected to the inlet 11 is closed, and the electronic valve of the other branch pipe is opened for discharge.

[0027] Preferably, a sludge discharge pipe 15 is provided at the bottom of the primary settling area 10 and the sedimentation area 50, and an electronic valve is provided at the end of the sludge discharge pipe 15 and is connected to a sludge collector, so that the discharge and treatment of the sludge can be controlled.

[0028] Preferably, the microbial filler 60 is a microbial filler 60 with a higher specific surface area and better biological attachment performance. First, the microbial filler 60 with a high specific surface area can provide more attachment area, providing a good growth environment for the growth and reproduction of microorganisms, thereby increasing the number and activity of microorganisms and improving treatment efficiency. Secondly, good biological attachment performance can make it easier for microorganisms to attach to the filler surface, reduce the possibility of microbial loss, and maintain the stability and durability of the treatment system. In addition, the high-performance microbial filler 60 can also effectively adsorb and degrade pollutants, thereby improving the purification effect of wastewater. It should be noted that the anaerobic zone biological filler 23 is preferably a microbial filler 60 with a higher specific surface area and better biological attachment performance.

[0029] When the energy-saving baffled agricultural sewage integrated machine of the present application is used, the sewage first enters the primary sedimentation zone 10 through the inlet 11. The composite filter layer 12 of the primary sedimentation zone 10 plays a role of pretreatment, removes large particle impurities and suspended matter, and provides a water quality basis. The sewage treated in the primary sedimentation zone 10 enters the anaerobic zone 20. In the anaerobic zone 20, the sewage passes through the multiple arc-shaped upper baffles 21 and the vertical lower baffles 22, which optimizes the water flow dynamics, promotes the degradation of organic matter, and improves the treatment efficiency. The sewage treated in the anaerobic zone 20 enters the anoxic zone 30 and the aerobic zone 40. These two areas are filled with microbial fillers 60, and the density gradually increases. The anoxic zone 30 provides a better biological attachment and growth environment, which is conducive to the further degradation of organic matter. The aerobic zone 40 is equipped with an aeration device to increase the dissolved oxygen content, promote the metabolism of microorganisms, and further improve the treatment efficiency. The sewage treated in the aerobic zone 40 enters the artificial wetland area 70. The aquatic plants planted in the artificial wetland area 70 absorb nutrients and organic matter in the water, and release oxygen at the same time, promoting the growth and metabolism of microorganisms in the water. In addition, the microorganisms in the wetland soil can also degrade and transform the organic matter in the sewage, thereby further improving the sewage treatment efficiency and purifying the water quality. Then the water treated in the artificial wetland area 70 enters the sedimentation area 50. Through the sludge discharge pipe 15 set at the bottom of the sedimentation area 50, the sludge is discharged and collected centrally. The treated water is treated in the sedimentation area 50 and discharged through the outlet 13. It should be noted that a water quality detector is set in the sedimentation area 50 to monitor the water quality in real time. According to the monitoring data, the operator can adjust the operating parameters of the treatment equipment to ensure that the treatment system always remains in the best operating state, thereby improving the treatment efficiency and water quality stability.

[0030] The utility model provides an energy-saving baffled agricultural sewage integrated machine, comprising a machine housing 1, wherein the interior of the machine housing 1 is sequentially divided into a primary sedimentation zone 10, an anaerobic zone 20, an anoxic zone 30, an aerobic zone 40, an artificial wetland zone 70 and a sedimentation zone 50 by a plurality of partitions 14. The composite filter layer 12 contained in the primary sedimentation zone 10 can effectively remove impurities and suspended matter in sewage, and provide a certain water quality basis for subsequent treatment. The arc-shaped upper baffle 21 and the vertical lower baffle 22 in the anaerobic zone 20 optimize the water flow dynamics, promote the degradation of organic matter, and improve the treatment efficiency. At the same time, the anaerobic zone biological filler 23 is filled between the baffle 14 on one side of the primary sedimentation zone 10 and the first vertical lower baffle 22 and between the baffle 14 on one side of the anoxic zone 30 and the last vertical lower baffle 22, so that the anaerobic zone biological filler 23 is at the initial and terminal positions of the sewage flow, which is conducive to making full use of the organic matter in the sewage for anaerobic degradation and maximizing the degradation efficiency of the organic matter. At the same time, filling the anaerobic zone biological filler 23 can effectively prevent the loss of sludge, ensuring that the sludge can be effectively deposited and discharged centrally during the treatment process, thereby reducing the risk of blockage and unstable operation of the treatment system.

[0031] The density of the microbial filler 60 filled in the anoxic zone 30 and the aerobic zone 40 gradually increases, providing a good environment for the attachment, growth and activity of microorganisms, which is conducive to the further degradation and transformation of organic matter. Specifically, the density of the microbial filler 60 in the anoxic zone 30 is relatively low, which is conducive to the reproduction and growth of anaerobic microorganisms, thereby promoting the initial degradation of organic matter. The density of the microbial filler 60 in the aerobic zone 40 is relatively high, which provides sufficient growth space and nutrients for aerobic microorganisms, which is conducive to the further degradation and transformation of organic matter and improves the treatment efficiency. The artificial wetland area 70 is set at the end to provide an ecosystem, where the planted aquatic plants can absorb nutrients and organic matter in the water, release oxygen at the same time, and promote the growth and metabolism of microorganisms in the water. In addition, the microorganisms in the wetland soil can also degrade and transform organic matter in sewage, thereby further improving the treatment efficiency of sewage and purifying water quality. At the same time, the microbial filler 60 in the aerobic zone 40 is equipped with an aeration device, which increases the dissolved oxygen content, promotes the metabolism of microorganisms, and further improves the treatment efficiency of wastewater. Therefore, this energy-saving baffled agricultural sewage integrated machine can stably meet the requirements of effluent water quality and meet the environmental protection standards and requirements of sewage treatment, while reducing energy consumption and lowering operating costs, and is suitable for the field of rural domestic sewage treatment.

[0032] The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
