Description

Technical Field

[0001] The present invention relates to the technical field of domestic sewage treatment, and in particular to an integrated sewage treatment device and a sewage treatment system. Background Art

[0002] With the rapid growth of the global population, the human living environment is facing unprecedented challenges, and this trend is particularly evident in both urban and rural areas. The problem of environmental pollution in rural areas has become increasingly prominent, becoming a major obstacle to the sustainable development of rural areas. The main reasons for the deterioration of the rural living environment include but are not limited to: the random discharge of untreated sewage, the disorderly disposal of garbage, the burning of crop straw, etc. Among them, the disorderly discharge of sewage is particularly serious and has become a key factor affecting the quality of rural living environment.

[0003] Specifically, the sewage discharge problems in rural areas are complex and diverse. Some aquaculture wastewater is directly discharged into surrounding water bodies, such as ditches and rivers, without any treatment measures, causing the water quality of these water bodies to drop sharply and the ecosystem to be seriously damaged. This phenomenon not only threatens the drinking water safety of rural residents, but also affects the quality of agricultural irrigation water, further exacerbating the deterioration of the rural ecological environment.

[0004] In view of the above problems, strengthening the effective collection, treatment and resource utilization of rural domestic sewage has become an urgent task to improve the rural living environment. However, the current application of rural domestic sewage treatment technology faces many challenges. On the one hand, due to regional environmental differences and the level of rural economic development, there are large differences in the choice of sewage treatment technology in different regions. Although biological ecological combination treatment technologies such as artificial wetlands, biological ponds, biogas purification tanks, and biofilters are relatively mature and can effectively degrade pollutants and remove nutrients such as nitrogen and phosphorus in sewage, the implementation of these technologies often relies on pipe network collection systems, with high construction costs, and requires centralized treatment sites, frequent operation and maintenance, and high management costs, which puts high demands on rural economic and technical forces.

[0005] On the other hand, the dispersed living conditions, complex terrain conditions and lack of a complete sewage collection network in rural areas make sewage collection a major problem. In addition, some farmers also engage in small-scale livestock and poultry farming, and the generated aquaculture sewage lacks effective disposal channels, further increasing the difficulty of rural sewage treatment.

[0006] Therefore, developing a technology suitable for decentralized sewage treatment in rural areas that can both effectively reduce costs and adapt to the complex environmental conditions in rural areas has become a technical problem that needs to be solved urgently. Summary of the invention

[0007] The purpose of the present invention is to provide an integrated sewage treatment device and a sewage treatment system to solve the problems existing in the above-mentioned prior art.

DETAILED DESCRIPTION

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide an integrated sewage treatment device and a sewage treatment system to solve the problems existing in the prior art. The sewage is distributed to the filter components for filtration by using a water distributor in a water distribution pool. The treated sewage enters an intermediate pool for reprocessing, forming an integrated sewage treatment device that flows from top to bottom. The device can be flexibly applied to rural areas of different sizes and conditions, and can realize on-site collection, treatment and resource utilization of sewage, thereby effectively improving the rural living environment and promoting the sustainable development of rural areas.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 10As shown, the present invention provides an integrated sewage treatment device, including a water distribution pool 4, a water distributor 10, a filter assembly 11, an intermediate pool 5 and a reprocessing assembly. The water distributor 10 is arranged in the water distribution pool 4. A plurality of water distributors 10 may be arranged in the water distribution pool 4. The inlet of the water distributor 10 is connected to the water distribution pool 4. When the sewage in the water distribution pool 4 enters the water distributor 10, the water distributor 10 can distribute the sewage to the filter assembly 11 connected to the water distributor 10, and then the filter assembly 11 is used to filter and treat the sewage. The filter assembly 11 includes a filter barrel 24 and a filter structure arranged in the filter barrel 24. The filter barrel 24 is located below the water distributor 10. The inlet of the filter barrel 24 is connected to the outlet of the water distributor 10. The sewage entering the water distributor 10 enters the filter barrel 24 after passing through the water distributor 10. After the sewage is filtered by the filter structure in the filter barrel 24, it is discharged from the filter barrel 24 and can enter the filter assembly 11 of the next layer for further filtration or directly enter the intermediate pool 5. The intermediate pool 5 is located below the filter barrel 24 of the last layer, and the outlet of the filter barrel 24 is connected to the intermediate pool 5. After the sewage is filtered by the primary or multi-stage filter assembly 11, it enters the intermediate pool 5 from the filter barrel 24, and the intermediate pool 5 collects and temporarily stores the filtered sewage. The reprocessing assembly is arranged in the intermediate pool 5, and the reprocessing assembly includes a sterilizing device and a deodorizing device to sterilize and deodorize the sewage in the intermediate pool 5, and the sewage that reaches the standard is discharged from the intermediate pool 5 for recycling and utilization.

[0037] The present invention arranges the water distribution pool 4, the filter assembly 11 and the intermediate pool 5 in sequence from top to bottom, and can utilize the water distributor 10 in the water distribution pool 4 to distribute sewage to the filter assembly 11 for filtration. The treated sewage enters the intermediate pool 5 for sterilization, deodorization and other re-treatments, thereby forming an integrated sewage treatment device that flows from top to bottom. The device can be flexibly applied to rural areas of different sizes and conditions, and realizes on-site collection, treatment and resource utilization of sewage, thereby effectively improving the rural living environment and promoting the sustainable development of rural areas.

[0038] In one embodiment, if Fig. 9 and Fig.10As shown, the water distributor 10 includes a water distribution bucket 28 and a first water medium disposed at the bottom of the water distribution bucket 28. The side wall of the water distribution bucket 28 higher than the first water medium is provided with a first through hole 29. A plurality of first through holes 29 can be evenly arranged on the water distribution bucket 28. When the liquid level of the sewage in the water distribution pool 4 reaches the height of the first through hole 29, the sewage can enter the water distribution bucket 28 through the first through hole 29. At this time, the water distribution pool 4 below the height of the first through hole 29 can be used as a sedimentation area for sewage, that is, heavier and larger impurities in the sewage can be temporarily stored after sedimentation in the sedimentation area, and the surface sewage slowly enters the water distribution bucket 28 through the first through hole 29 for sewage distribution. At the same time, the first through hole 29 can also play a filtering role, intercepting larger impurities to achieve efficient filtration. In addition, the water distribution pool 4 and the water distributor 10 can adopt a detachable structure to facilitate the cleaning of impurities precipitated or filtered in the water distribution pool 4. A second through hole is provided at the bottom of the water distribution bucket 28, the first through hole 29 serves as the inlet of the water distributor 10, and the second through hole serves as the outlet of the water distributor 10. The first water-passing medium is a sponge-like material 12, which can slow down the flow of water, so that the sewage slowly and continuously enters the filter assembly 11 for filtration, thereby improving the uniform water distribution effect. The sewage enters the water distribution bucket 28 through the first through hole 29, and after being saturated with water by the sponge-like material 12, it drips and flows out through the second through hole.

[0039] In one embodiment, if Figure 6 to Figure 8 As shown, the filtering structure includes a water-passing grid 26, a filter material 25 and a second water-passing medium arranged in sequence from top to bottom in the filter barrel 24. The water-passing grid 26 plays the role of intercepting impurities again and distributing water flow. The filter material 25 plays the role of filtering. The filter material 25 can be made of a porous structure material such as igneous rock, ceramsite, activated carbon, etc. The second water-passing medium uses a sponge material 12. The sponge material 12 can slow down the flow of water. Combined with its internal pores, the filtering effect can be further improved. A third through hole is opened at the top of the filter barrel 24, and a fourth through hole is opened at the bottom of the filter barrel 24. The third through hole serves as the inlet of the filter barrel 24, and the fourth through hole serves as the outlet of the filter barrel 24. After the sewage flows out from the second through hole of the water distributor 10, it enters the filter barrel 24 through the third through hole of the filter barrel 24, passes through the water-passing grid 26, the filter material 25 and the sponge material 12 in sequence, and then drips and flows out from the fourth through hole to enter the intermediate pool 5.

[0040] In one embodiment, if Figure 2 As shown, it also includes a monitoring probe 17, which is arranged in the middle tank 5. The monitoring probe 17 can monitor the pH, turbidity, conductivity, nitrogen, phosphorus, etc. of the sewage in the middle tank 5 to determine whether the sewage meets the standards.

[0041] In one embodiment, if Figure 4As shown, it also includes a reflux valve 20 and a discharge valve 21, and both the reflux valve 20 and the discharge valve 21 can adopt electromagnetic valves to automatically control the opening and closing. The monitoring result of the monitoring probe 17 is used to link the opening and closing of the reflux valve 20 or the discharge valve 21. When the sewage in the intermediate pool 5 meets the standard, it enters the drain pipe 22 through the discharge valve 21. If the monitored sewage in the intermediate pool 5 does not meet the requirements, it returns to the water distribution pool 4 or the sewage pool through the reflux valve 20 for reprocessing. The discharged sewage and the returned sewage both flow under the action of pumping.

[0042] In one embodiment, if Figure 1 to Figure 3 As shown, it also includes a frame 1, a load-bearing column 3 and a load-bearing plate 13. The top and bottom ends of the load-bearing column 3 are fixedly connected to the frame 1. The frame 1 is installed on the base 6. The base 6 has legs, which can lift the frame 1 to a certain height, facilitate installation on uneven ground, and improve the stability of the device operation. The load-bearing plate 13 is arranged on the load-bearing column 3 at intervals, and the frame 1 and the load-bearing column 3 are used to support the load-bearing plate 13. The water distribution pool 4 and the filter assembly 11 are respectively located on different load-bearing plates 13, and can be disassembled and installed as needed.

[0043] In one embodiment, if Figure 5 As shown, the load-bearing plate 13 is provided with a slot 27, and the water distribution bucket 28 of the water distributor 10 and the filter barrel 24 of the filter assembly 11 can be installed in the slot 27 for fixation. The water distribution bucket 28 can be connected to the filter barrel 24 of the lower layer, and the filter barrel 24 can be connected to the filter barrel 24 of the lower layer or directly connected to the middle pool 5.

[0044] In one embodiment, the main body of the frame 1 and the filter assembly 11 are made of corrosion-resistant, sun-resistant and antifreeze materials (such as stainless steel or PVC), and the load-bearing column 3 and the load-bearing plate 13 are made of stainless steel. The power can be household electricity or solar energy.

[0045] In one embodiment, if Figure 1 to Figure 4 As shown, it also includes a control system 9, which is electrically connected to the monitoring probe 17, the reflux valve 20 and the discharge valve 21 respectively. The data monitored by the monitoring probe 17 can be transmitted to the control system 9, and the control system 9 can send control signals to the reflux valve 20 and the discharge valve 21 to achieve the discharge and reflux of sewage according to the sewage treatment situation. The frame 1 is covered with a shell, which closes the frame 1. The shell is provided with a door 2, and the door 2 is provided with a lockable handle 23, which is convenient for opening and closing the door 2 and locking it after closing the door 2. The provision of the door 2 can facilitate the installation, replacement or maintenance of components such as the filter assembly 11. The control system 9 is installed on the shell and can be located on the side of the shell. The opening and closing of the door 2 does not affect the operation of the control system 9.

[0046] In one embodiment, the sterilization device uses an ultraviolet lamp 16, which can be installed on the side wall of the middle pool 5, and can be immersed in the water or located above the water surface.

[0047] In one embodiment, the deodorizing device uses an exhaust fan 14 and an adsorption device. The exhaust fan 14 can be installed at the bottom of the load-bearing plate 13 above the middle pool 5. The shell is provided with ventilation holes. The adsorption device can be arranged on the path of the airflow to the ventilation holes. The exhaust fan 14 is used to blow the airflow to the adsorption device, and the adsorption device is used to adsorb the odor. The adsorbed gas is discharged to the outside of the shell to perform deodorizing.

[0048] In one embodiment, the adsorption device uses a biochar curtain 15, which is located between the water distribution pool 4 and the middle pool 5 and hangs down in a curtain shape. The biochar curtain 15 can eliminate the odor of sewage inside the device. The exhaust fan 14 can blow the airflow toward the biochar curtain 15 first, and then flow to the outside of the shell after being deodorized by the biochar curtain 15.

[0049] The integrated sewage treatment device of the present invention has the characteristics of small size, small footprint and modular installation. It is suitable for domestic sewage treatment of farmers living in scattered areas, and can treat sewage from a small number of pigs, cattle, sheep and other livestock and poultry raised by farmers. The device has low energy consumption and can use various energy sources such as household electricity and solar energy as power sources. Moreover, the filter component 11 is assembled, which is easy to replace and maintain.

[0050] like Figures 1 to 10 As shown, the present invention also provides a sewage treatment system, comprising at least two integrated sewage treatment devices as described above arranged in parallel, and also provided with a sewage pump 7 and a pipeline 8, wherein the sewage pump 7 extracts sewage through the pipeline 8 and flows into the water distribution pool 4 at the top of the integrated sewage treatment device. The water inlets of multiple integrated sewage treatment devices can be connected in parallel to the same sewage pump 7, and in this case, the pipeline 8 can be provided with multiple branches connecting the integrated sewage treatment devices. In addition, the water outlets of multiple integrated sewage treatment devices can be directed to the same discharge pipe network in the same direction.

[0051] The integrated sewage treatment device of the present invention can be used in combination of two or more groups to meet the needs of a large family or several households; it solves the problems of difficult pipe laying, difficult sewage collection, high investment, large site occupation, frequent maintenance, high management costs, and the need for professional technicians in traditional centralized sewage treatment.

[0052] The working principle of the integrated sewage treatment device of the present invention:

[0053] The integrated sewage treatment device is installed next to the three-compartment septic tank (sewage tank) of the farmer's household. The sewage of the three-compartment septic tank is pumped into the water distribution tank 4 through the sewage pump 7. When the water level of the water distribution tank 4 rises to the first through hole 29 (water distribution hole) above the water distributor 10, the sewage falls into the first water medium in the water distributor 10 through the first through hole 29. After the first water medium is saturated with water, the sewage drips into the filter barrel 24 of the filter component 11 below, and falls into the second water medium after being filtered by the filter material 25, and then enters the next filter component 11 until it enters the middle tank 5 at the bottom. The harmful bacteria in the sewage are killed by ultraviolet irradiation in the middle tank 5. The monitoring probe 17 of the middle tank 5 performs an index test on the sewage entering therein. The test results can be viewed on-site in the visualization window 19, and can also be viewed remotely through the data platform; if the discharge standard is met, the discharge valve 21 is activated, and the sewage enters the discharge pipe network through the drain pipe 22 for discharge. If the discharge standard is not met, the sewage flows back to the water distribution tank 4 or the three-compartment septic tank through the reflux valve 20 for a second treatment until the sewage meets the discharge standard. During the sewage treatment process, the exhaust fan 14 increases air circulation, and the biochar curtain 15 eliminates the odor of sewage. The frame 1 can be customized according to the construction of new rural areas and beautiful villages. Two or three devices can also be used in parallel according to the amount of sewage to treat sewage from joint households or multiple households.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
