Description

Technical Field

[0001] This utility model belongs to the field of domestic sewage treatment technology, and specifically relates to an integrated domestic sewage treatment device. Background Technology

[0002] my country has a large rural population. With the increasing emphasis placed on building beautiful rural environments by national and local governments and the continuous advancement of new rural construction, the living standards of rural residents are constantly improving, and their demands for their living environment are also rising. Among rural environmental pollution issues, sewage pollution is a prominent problem. It not only poses a potential threat to rural water sources but may also exacerbate freshwater shortages, affect farmland irrigation, and ultimately threaten the survival and development of farmers. Therefore, the state requires that rural sewage discharge must meet prescribed standards. To achieve this goal, rural sewage needs to be purified for reuse. This not only helps protect and improve the rural environment but also promotes the sustainable use of resources, supporting sustainable rural development.

[0003] In existing domestic sewage treatment processes, large residues are typically filtered out using mechanical bar screens before being discharged into integrated domestic sewage treatment plants for further processing. However, due to cost considerations, rural areas often opt for small to medium-sized integrated domestic sewage treatment plants without purchasing additional mechanical bar screens. This results in sewage containing large residues being directly discharged into these plants, requiring frequent and laborious cleaning, which causes inconvenience to the integrated treatment system. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an integrated domestic sewage treatment device to solve the problems described in the background section.

[0005] This utility model provides the following technical solution: an integrated domestic sewage treatment device, including a filtration device and a treatment device connected to the filtration device; the treatment device includes a tank and a contact oxidation tank, a sedimentation tank, a disinfection tank, a sludge tank and an effluent tank separated within the tank; the filtration device includes an inlet channel, a filtration channel connected to the inlet channel, and an equalization tank connected to the filtration channel; the filtration channel includes a main channel, an auxiliary channel and filter elements respectively installed in the main channel and the auxiliary channel; the main channel has a treatment port on one side; the treatment port, the main channel and the auxiliary channel are respectively equipped with connectors; the connectors are fitted with baffles to switch the working state of the main channel and the auxiliary channel; wherein, when the auxiliary channel is working, only the main channel has the baffle inserted; when the main channel is working, the auxiliary channel and the treatment port have the baffle inserted.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: First, baffles are inserted into the connectors on the treatment port and auxiliary channel to allow domestic sewage from the inlet channel to enter the main channel. Large residues from the domestic sewage are filtered through the filter elements in the main channel. The filtered domestic sewage then enters the equalization tank and then the treatment equipment to obtain water that meets discharge standards. When a large amount of residue accumulates at the filter elements and needs to be treated, the baffle on the auxiliary channel is pulled out and inserted into the connector on the main channel, thus blocking the main channel and opening the auxiliary channel. At this time, domestic sewage from the inlet channel enters the auxiliary channel, where it is filtered through the filter elements to remove large residues. The filtered domestic sewage then enters the equalization tank and then the treatment equipment to obtain water that meets discharge standards. Simultaneously, the baffle at the treatment port is pulled out to treat the accumulated residue. After treatment, baffles are inserted again into the connectors on the treatment port and auxiliary channel to allow domestic sewage from the inlet channel to continue entering the main channel. It can be seen that by coordinating the main channel, auxiliary channel, treatment port, and baffle, the option to insert or not insert baffles in the treatment port, the main channel, and the auxiliary channel can be selected to switch the working state of the main channel and the auxiliary channel, thereby processing a large amount of residue. This replaces the existing mechanical bar screen equipment for filtering residue, saves expenses, reduces the need for cleaning the integrated sewage treatment device, and improves the convenience of the integrated treatment device.

[0007] Furthermore, a submersible pump is installed in the equalization tank, and the submersible pump is connected to the bottom of the contact oxidation tank through a pumping pipe.

[0009] Furthermore, the contact oxidation tank is equipped with packing material.

[0010] Furthermore, the bottom of the sedimentation tank is inclined from both sides to the middle, and a sludge discharge valve is installed in the middle of the bottom of the sedimentation tank. The middle part of the contact oxidation tank is connected to the sedimentation tank through a water pipe.

[0011] Furthermore, the connector includes two opposing plugs and a mounting block disposed at the bottom between the two plugs, so that the connector is U-shaped. The two plugs are respectively provided with a first slot on their opposite sides, and the mounting block is provided with a second slot on its top.

[0012] Furthermore, the connector is an elastic rubber product, and the dimensions of the connectors on the processing port, the main channel, and the auxiliary channel correspond to each other.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 2As shown in the figure, an integrated domestic sewage treatment device according to an embodiment of the present invention includes a filtration device 10 and a treatment device 20 connected to the filtration device 10. The treatment device 20 includes a housing 21 and a contact oxidation tank 22, a sedimentation tank 23, a disinfection tank 24, a sludge tank 25, and an effluent tank 26 separated within the housing 21. The filtration device 10 includes an inlet channel 11, a filtration channel 12 connected to the inlet channel 11, and an equalization tank 13 connected to the filtration channel 12. The filtration channel 12 includes a main channel 121, an auxiliary channel 122, and equalization tanks 13 respectively disposed within the main channel 121. The filter element 16 of channel 121 and the auxiliary channel 122, the main channel 121, the processing port 17 opened on one side of the main channel 121, the processing port 17, the main channel 121 and the auxiliary channel 122 are respectively equipped with plug-in parts 18, the plug-in parts 18 are equipped with baffles 19 to switch the working state of the main channel 121 and the auxiliary channel 122. When the auxiliary channel 122 is working, only the baffle 19 is inserted into the main channel 121. When the main channel 121 is working, the baffle 19 is inserted into the auxiliary channel 122 and the processing port 17.

[0026] It is worth noting that, firstly, baffles 19 are inserted into the connectors 18 on the treatment port 17 and the auxiliary channel 122, so that the domestic sewage from the inlet channel 11 enters the main channel 121. Large residues from the domestic sewage are filtered through the filter element 16 in the main channel 121. The filtered domestic sewage then enters the equalization tank 13, and then enters the treatment equipment 20 for treatment to obtain water that meets discharge standards. When a large amount of residue accumulates at the filter element 16 and needs to be treated, the baffles 19 on the auxiliary channel 122 are pulled out and inserted into the connectors 18 on the main channel 121, so that… The main channel 121 is blocked, and the auxiliary channel 122 is opened. At this time, the domestic sewage from the inlet channel 11 enters the auxiliary channel 122 and is filtered by the filter element 16 of the auxiliary channel 122 to remove large residues. The filtered domestic sewage enters the equalization tank 13 and then enters the treatment equipment 20 for treatment to obtain water that meets the discharge standards. At the same time, the baffle 19 at the treatment port 17 is pulled out to treat the accumulated residues. After the treatment is completed, the baffle 19 is inserted again into the connector 18 on the treatment port 17 and the auxiliary channel 122 so that the domestic sewage from the inlet channel 11 can continue to enter the main channel 121. It can be seen that by cooperating with the main channel 121, the auxiliary channel 122, the treatment port 17, and the baffle 19, the baffle 19 can be selected to be inserted or not in the treatment port 17, the main channel 121, and the auxiliary channel 122, so as to switch the working state of the main channel 121 and the auxiliary channel 122. In this way, a large amount of residue can be processed, replacing the existing mechanical bar screen equipment to filter the residue, saving expenses, reducing the cleaning of the integrated sewage treatment device, and improving the convenience of the integrated treatment device.

[0027] Specifically, a submersible pump 14 is installed in the equalization tank 13, and the submersible pump 14 is connected to the bottom of the contact oxidation tank 22 through a pumping pipe 15.

[0028] Specifically, the housing 21 is divided into a power compartment 27, a fan 30 is installed in the power compartment 27, the fan 30 is connected to a conveying pipe 31, the conveying pipe 31 extends to the bottom of the contact oxidation tank 22 and is connected to an exhaust pipe 32, and the exhaust pipe 32 is provided with multiple exhaust ports 33.

[0029] Specifically, the contact oxidation tank 22 is equipped with packing material 221.

[0030] Specifically, the bottom of the sedimentation tank 23 is inclined from both sides to the middle, and a sludge discharge valve is installed in the middle of the bottom of the sedimentation tank 23. The middle part of the contact oxidation tank 22 is connected to the sedimentation tank 23 through a water pipe 222.

[0031] Please see Figures 3 to 5As shown, in this embodiment, the main channel 121 and the water inlet channel 11 are on the same straight line, the auxiliary channel 122 is on one side of the main channel 121, and the auxiliary channel 122 is arranged parallel to the main channel 121. The two ends of the auxiliary channel 122 are respectively connected to the two ends of the main channel 121 through the connecting channel 1221.

[0032] The filter element 16, which is disposed in the main channel 121, is positioned close to the processing port 17. This close positioning facilitates the cleaning of the residue filtered by the filter element 16 in the main channel 121 using the processing port 17.

[0033] The connecting channel 1221, which is close to the water inlet channel 11, is located close to the treatment port 17. This proximity is also to facilitate the use of the treatment port 17 to clean the residue filtered by the filter element 16 in the auxiliary channel 122 (connecting channel 1221).

[0034] The filter element 16, located within the auxiliary channel 122, is positioned near the inlet of the connecting channel 1221, close to the inlet channel 11. This placement of the filter element 16 at the inlet of the connecting channel 1221 allows the residue filtered out in the auxiliary channel 122 (connecting channel 1221) to be flushed back into the main channel 121. This eliminates the need to clean the residue filtered out in the auxiliary channel 122; only the residue filtered out in the main channel 121 needs to be cleaned, thus improving cleaning convenience.

[0035] Furthermore, the connector 18 includes two opposing insert blocks 181 and a mounting block 182 disposed at the bottom between the two insert blocks 181, so that the connector 18 presents a U-shape. First slots 183 are respectively opened on opposite sides of the two insert blocks 181, and a second slot 184 is opened on the top of the mounting block 182. It can be understood that the two opposing insert blocks 181 of the connector 18 disposed in the processing port 17 are respectively disposed on both sides of the inner wall of the processing port 17, and its mounting block 182 is disposed at the bottom of the processing port 17. The two insert blocks 181 of the connector 18 disposed in the connecting channel 1221 are respectively disposed on both sides of the inner wall of the connecting channel 1221, and its mounting block 182 is disposed at the bottom of the connecting channel 1221. The two insert blocks 181 of the connector 18 disposed in the main channel 121 are respectively disposed on both sides of the inner wall of the main channel 121, and its mounting block 182 is disposed at the bottom of the main channel 121. In this embodiment, the connector 18 in the main channel 121 is inclined so that the baffle 19 inserted into the main channel 121 has a guiding effect, guiding domestic sewage to the connecting channel 1221.

[0036] Specifically, the connector 18 is an elastic rubber product. By using the rubber product, the sealing between the connector 18 and the baffle 19 can be improved.

[0037] The dimensions of the connectors 18 on the processing port 17, the main channel 121, and the auxiliary channel 122 correspond to each other. By setting the dimensions accordingly, a baffle 19 can be inserted into the processing port 17, the main channel 121, or the auxiliary channel 122.

[0038] In this embodiment, the contact oxidation tank 22 includes an anaerobic tank, an anoxic tank, and an aerobic tank. The filter element 16 can be a filter screen or a grid. The top of the housing 21 is connected to multiple manholes 211, the effluent tank 26 is connected to an effluent outlet 261, the sludge tank 25 is connected to a supernatant return outlet 251, and the power compartment 27 is connected to a vent 271.

[0039] In summary, the integrated domestic sewage treatment device in the above embodiments of this utility model first inserts baffles 19 onto the connectors 18 on the treatment port 17 and the auxiliary channel 122, so that the domestic sewage from the inlet channel 11 enters the main channel 121. Large residues from the domestic sewage are filtered through the filter element 16 in the main channel 121. The filtered domestic sewage then enters the equalization tank 13 and then the treatment equipment 20 for further treatment to obtain water that meets discharge standards. When a large amount of residue accumulates at the filter element 16 and needs to be treated, the baffles 19 on the auxiliary channel 122 are pulled out and inserted into the main channel 121. The main channel 121 is blocked and the auxiliary channel 122 is opened. At this time, the domestic sewage from the inlet channel 11 enters the auxiliary channel 122 and is filtered by the filter element 16 of the auxiliary channel 122 to remove large residues. The filtered domestic sewage enters the equalization tank 13 and then enters the treatment equipment 20 for treatment to obtain water that meets the discharge standards. At the same time, the baffle 19 at the treatment port 17 is pulled out to treat the accumulated residues. After the treatment is completed, the baffle 19 is inserted again on the connector 18 on the treatment port 17 and the auxiliary channel 122 so that the domestic sewage from the inlet channel 11 can continue to enter the main channel 121. It can be seen that by cooperating with the main channel 121, the auxiliary channel 122, the treatment port 17, and the baffle 19, the baffle 19 can be selected to be inserted or not in the treatment port 17, the main channel 121, and the auxiliary channel 122, so as to switch the working state of the main channel 121 and the auxiliary channel 122. In this way, a large amount of residue can be processed, replacing the existing mechanical bar screen equipment to filter the residue, saving expenses, reducing the cleaning of the integrated sewage treatment device, and improving the convenience of the integrated treatment device.
