At present, common sewage treatment devices are widely used in urban sewage treatment, industrial park wastewater treatment, rural domestic sewage treatment and tourist area sewage treatment.

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0038] With the development of science and technology, the issue of sewage treatment has attracted more and more attention. At present, common sewage treatment devices are widely used in urban sewage treatment, industrial park wastewater treatment, rural domestic sewage treatment and tourist area sewage treatment. These treatment devices usually use advanced biological treatment technology and physical and chemical treatment methods to remove harmful substances in sewage and meet emission standards or realize resource utilization.

[0039] Traditional sewage treatment devices include agitators, filters, and aerators. The agitator is used to stir the sewage, the filter is used to filter the sewage, and oxygen is forced into the sewage through the aerator, so that organic matter, microorganisms, and dissolved oxygen can be fully contacted, and the oxidation and decomposition efficiency of organic matter in the sewage can be improved, so that organic matter, nitrogen, phosphorus and other pollutants in the sewage can be efficiently adsorbed and degraded, so that the sewage treatment device can purify the sewage. However, when this structure is adopted, the cost of the agitator, filter, and aerator is high and the energy consumption is large, resulting in a high cost of using the traditional sewage treatment device.

[0040] On the other hand, most of the traditional electric pulse sewage treatment equipment uses two large flat plates to release a pulse electric field to achieve water purification. This method will greatly reduce the generation of plasma and increase energy consumption. Plasma plays an indispensable role in sewage purification. Reducing plasma means reducing purification efficiency. On the other hand, most of the traditional electric pulse sewage treatment equipment does not further process the ozone generated when the pulse electric field ionizes the air during the purification process. Therefore, the water source needs to be treated again after purification, which also increases the cost.

[0041] See also Figure 1 and Figure 2The embodiment of the present invention provides a portable electric pulse sewage treatment device for small water areas, including a box body 1, wherein a sewage chamber 2, a water purification chamber 3 and a treatment chamber 4 are arranged in the box body 1, the sewage chamber 2 is used to store sewage, and a first needle electrode array 5 is arranged in the treatment chamber 4, the first needle electrode array 5 includes a plurality of needle electrodes distributed in an array, a pulse power supply 6 is arranged on the treatment chamber 4, and the pulse power supply 6 is electrically connected to the first needle electrode array 5, the inlet end of the treatment chamber 4 is connected to the sewage chamber 2, and the outlet end of the treatment chamber 4 is connected to the water purification chamber 3, and the sewage in the sewage chamber 2 is purified by the first needle electrode array 5 in the treatment chamber 4 and then flows into the water purification chamber 3 for storage.

[0042] In some embodiments of the present application, the sewage chamber 2 and the clean water chamber 3 are both located at the bottom of the box body 1, and the clean water chamber 3 is located above the sewage chamber 2, and the sewage chamber 2 and the clean water chamber 3 are separated by an isolation plate.

[0043] In some embodiments of the present application, the treatment chamber 4 is arranged in a vertical direction, and when sewage flows into the treatment chamber 4 , it can flow into the water purification chamber 3 through the first needle-shaped electrode array 5 under the action of gravity.

[0044] In some embodiments of the present application, the needle electrodes in the first needle electrode array 5 are arranged horizontally, and multiple needle electrodes are arranged in sequence in the vertical direction. After the sewage flows into the treatment chamber 4, it can pass through the multiple needle electrodes in sequence for electric pulse degradation, thereby improving the purification efficiency and effect of the sewage treatment device on sewage.

[0045] In some embodiments of the present application, the pulse power supply 6 can transmit high-frequency pulse current to the first needle-shaped electrode array 5, and the sewage can be electrolyzed by high-frequency pulses, which can improve the purification efficiency and effect of the sewage in the treatment chamber 4. In addition, the pulse power supply 6 can also transmit electric pulses of different frequencies to the first needle-shaped electrode array 5, and the sewage can be electrolyzed by electric pulses of different frequencies, so that the sewage treatment device can be applied to water bodies with different pollution degrees, thereby improving the scope of application of the sewage treatment device.

[0046] In the above scheme of the present application, the sewage treatment device includes a box 1, in which a sewage chamber 2, a water purification chamber 3 and a treatment chamber 4 are arranged. The sewage chamber 2 can store sewage, and a first needle electrode array 5 is arranged in the treatment chamber 4. The first needle electrode array 5 includes a plurality of needle electrodes distributed in an array. A pulse power supply 6 is arranged on the treatment chamber 4, and the pulse power supply 6 is electrically connected to the first needle electrode array 5. The inlet end of the treatment chamber 4 is connected to the sewage chamber 2, and the outlet end of the treatment chamber 4 is connected to the water purification chamber 3. The sewage in the sewage chamber 2 is purified by the first needle electrode array 5 in the treatment chamber 4 and flows into the water purification chamber 3 for storage. With this structure, the pulse power supply 6 transmits a pulse current to the first needle electrode array 5, and the first needle electrode array 5 performs irreversible electric pulse degradation on pollutants such as bacteria and organic matter in the sewage, so that the sewage treatment device can effectively purify the sewage. Among them, the discharge intensity of the needle tip part can be enhanced by a plurality of needle electrodes distributed in an array, thereby improving the treatment efficiency and purification effect of the sewage. Moreover, the sewage treatment device of the present application has a simple structure, low energy consumption, low cost and is easy to install and use, so that the use cost of the sewage treatment device is low. In addition, the structure of the present application is small in size and easy to carry.

[0047] In addition, the portable sewage treatment equipment of the present application has a needle array electrode plate, and the needle discharge method greatly improves the efficiency of plasma generation and reduces energy consumption. On the other hand, through the design of a novel external water circulation system, the heat on the pulse discharge electrode plate is used to promote the decomposition and volatilization of ozone in the water, which greatly improves the quality of the final water source and greatly reduces the cost of secondary treatment.

[0048] In some embodiments of the present application, Figure 1As shown, the box body 1 is also provided with a first pipeline 7, a second pipeline 8, a third pipeline 9, a valve 10 and a water inlet pump 17. The first pipeline 7 is connected to the inlet end of the treatment chamber 4, one end of the second pipeline 8 is connected to the sewage chamber 2, the other end of the second pipeline 8 is connected to the first pipeline 7, one end of the third pipeline 9 is connected to the clean water chamber 3, and the other end of the third pipeline 9 is connected to the first pipeline 7; the valve 10 is arranged on the first pipeline 7, and is used to control the communication between the first pipeline 7 and the second pipeline 8 or the third pipeline 9; the water inlet pump 17 is arranged on the first pipeline 7, and is used to pump water in the sewage chamber 2 or the clean water chamber 3 into the treatment chamber 4. With this structure, when the sewage treatment device is used, the sewage in the sewage chamber 2 can be first pumped into the treatment chamber 4 for purification through the water inlet pump 17, and the water purified by the treatment chamber 4 flows to the clean water chamber 3 for storage, and then the water stored in the clean water chamber 3 after the first purification is pumped into the treatment chamber 4 for secondary purification through the water inlet pump 17, and the water purified by the treatment chamber 4 flows to the clean water chamber 3 for storage, and then the water in the clean water chamber 3 is repeatedly pumped into the treatment chamber 4 for circulation purification to obtain clean water that meets the requirements. In this way, the water in the clean water chamber 3 can be circulated for multiple times through this structure, thereby improving the purification effect of the sewage treatment device.

[0049] In some embodiments of the present application, the valve 10 can be a two-position three-way solenoid valve, whose three interfaces are respectively connected to the first pipeline 7, the second pipeline 8 and the third pipeline 9 to control one of the second pipeline 8 and the third pipeline 9 to be connected to the first pipeline 7.

[0050] In some embodiments of the present application, a first water level sensor 11 is provided in the sewage chamber 2, and the first water level sensor 11 is arranged at the bottom of the sewage chamber 2, and is used to detect whether the sewage water level in the sewage chamber 2 reaches a preset minimum water level; a first controller is also provided in the box body 1, and the first water level sensor 11 and the valve 10 are both connected to the control. The first controller is used to control the first pipeline 7 and the second pipeline 8 to be connected through the valve 10 when the first water level sensor 11 does not detect that the sewage water level in the sewage chamber 2 reaches the preset minimum water level, and to control the first pipeline 7 and the third pipeline 9 to be connected through the valve 10 when the first water level sensor 11 detects that the sewage water level in the sewage chamber 2 reaches the preset minimum water level. With this structure, when the first water level sensor 11 does not detect that the sewage water level in the sewage chamber 2 has reached the preset minimum water level, it is still necessary to pump the sewage in the sewage chamber 2 into the treatment chamber 4 for purification through the water inlet pump 17. At this time, the valve 10 is controlled by the first controller to operate so that the first pipeline 7 and the second pipeline 8 are connected, thereby ensuring that the sewage in the sewage chamber 2 can flow into the treatment chamber 4 through the second pipeline 8 and the first pipeline 7. When the first water level sensor 11 detects that the sewage water level in the sewage chamber 2 has reached the preset minimum water level, the sewage chamber 2 no longer provides sewage to the treatment chamber 4. At this time, the valve 10 is controlled by the first controller to operate so that the first pipeline 7 and the third pipeline 9 are connected, so that the water in the water purification chamber 3 can be pumped into the treatment chamber 4 through the water inlet pump 17 for multiple cycles of purification.

[0051] In some embodiments of the present application, the first water level sensor 11 is a device capable of converting a measured water level signal into an electrical signal in real time, such as a piezoelectric water level sensor, a capacitive water level sensor, etc. The first water level sensor 11 is installed below the side wall of the sewage chamber 2 and there is a gap between the first water level sensor 11 and the bottom surface of the sewage chamber 2 to facilitate the installation and fixation of the first water level sensor 11.

[0052] In some embodiments of the present application, a second water level sensor 12 is provided in the sewage chamber 2, and the second water level sensor 12 is arranged at the top of the sewage chamber 2, and is used to detect whether the sewage water level in the sewage chamber 2 has reached a preset maximum water level; a water inlet valve 23 is provided on the side wall of the sewage chamber 2, and a second controller is also provided in the box body 1, and the second water level sensor 12 and the water inlet valve 23 are both connected to the second controller, and the second controller is used to control the closing of the water inlet valve 23 when the second water level sensor 12 detects that the sewage water level in the sewage chamber 2 has reached a preset maximum water level. With this structure, when the second water level sensor 12 does not detect that the sewage water level in the sewage chamber 2 has reached the preset maximum water level, it is still necessary to introduce the sewage outside the box body 1 into the sewage chamber 2 through the water inlet valve 23. At this time, the water inlet valve 23 is controlled to open by the second controller, so that the sewage outside the box body 1 can flow into the sewage chamber 2. When the second water level sensor 12 detects that the sewage water level in the sewage chamber 2 has reached a preset maximum water level, the sewage chamber 2 no longer needs to introduce sewage. At this time, the second controller controls the water inlet valve 23 to close, so that the sewage chamber 2 is separated from the sewage outside the box body 1, so that the sewage outside the box body 1 will not flow into the sewage chamber 2.

[0053] In some embodiments of the present application, the second water level sensor 12 is a device capable of converting the measured water level signal into an electrical signal in real time, such as a piezoelectric water level sensor, a capacitive water level sensor, etc. The second water level sensor 12 is installed above the side wall of the sewage chamber 2 and there is a gap between the second water level sensor 12 and the top surface of the sewage chamber 2, so as to facilitate the installation and fixation of the second water level sensor 12.

[0054] In some embodiments of the present application, the first controller and the second controller may be two different controllers or may be the same controller.

[0055] In some embodiments of the present application, a filter net is provided on the water inlet valve 23, through which objects such as suspended particles and fibers in sewage can be filtered.

[0056] In some embodiments of the present application, Figure 1 and Figure 3As shown, the first needle electrode array 5 includes a positive electrode array and a negative electrode array arranged oppositely, the positive electrode array includes a plurality of needle electrodes distributed along the first direction, and the negative electrode array includes a plurality of needle electrodes distributed along the first direction; the needle electrode includes an electrode plate 51, an insulating layer 52 and a needle head 53, the pulse power supply 6 is electrically connected to the electrode plate 51, the needle head 53 is electrically connected to the electrode plate 51, and the insulating layer 52 is wrapped around the end connected to the needle head 53 and the electrode plate 51. With this structure, after the sewage flows into the treatment chamber 4, it can be sequentially passed through the plurality of needle electrodes on the positive electrode array and the negative electrode array for pulse electrolysis, thereby improving the purification effect of the treatment chamber 4 on the sewage. Among them, the electrode plate 51 can provide a pulse current for the needle head 53, the needle tip part of the needle head 53 can enhance the discharge intensity, and can increase the gap between two adjacent needle electrodes, so that more sewage can flow through the needle tip part of the needle head 53, so that the contact between the sewage and the needle electrode is more sufficient and uniform, thereby further improving the purification effect of the treatment chamber 4 on the sewage. In addition, the insulating layer 52 can also prevent mutual interference between two adjacent needles 53, thereby increasing the output frequency of the needle-shaped electrode and reducing the additional capacitance effect.

[0057] In some embodiments of the present application, the first direction is the height direction of the box body 1 .

[0058] In some embodiments of the present application, the material of the electrode plate 51 can be a corrosion-resistant good conductor such as stainless steel, the material of the insulating layer 52 can be an insulating material such as polytetrafluoroethylene (PTFE), modified polyoxymethylene (POM), polyphenylene sulfide (PPS), etc., and the material of the needle tip can be a corrosion-resistant good conductor such as stainless steel.

[0059] In some embodiments of the present application, an ozone chamber 13, a first air pipe 14 and a second air pipe 15 are further provided in the box body 1; one end of the first air pipe 14 is connected to the outside of the box body 1, and the other end is connected to the inlet end of the ozone chamber 13; one end of the second air pipe 15 is connected to the outlet end of the ozone chamber 13, and the other end is connected to the inlet end of the treatment chamber 4; a second needle-shaped electrode array 26 is provided in the ozone chamber 13, and ozone is generated when the gas in the first air pipe 14 passes through the second needle-shaped electrode array 26, and the ozone is transmitted to the treatment chamber 4 through the second air pipe 15. With this structure, when the air in the first air pipe 14 passes through the discharge gap between two adjacent needle electrodes in the second needle electrode array 26, the oxygen molecules in the air are excited by the electrons to obtain energy and collide with each other to aggregate into ozone molecules, so that ozone can be generated when the gas in the first air pipe 14 passes through the second needle electrode array 26. The ozone is transmitted to the treatment chamber 4 through the second air pipe 15, and the sewage in the treatment chamber 4 can be purified, thereby further improving the purification effect of the treatment chamber 4 on the sewage.

[0060] In some embodiments of the present application, the structure of the second needle-shaped electrode array 26 is the same as that of the first needle-shaped electrode array 5. The second needle-shaped electrode array 26 is also composed of a positive electrode array and a negative electrode array. The positive electrode array includes a plurality of needle-shaped electrodes distributed along the first direction, and the negative electrode array includes a plurality of needle-shaped electrodes distributed along the first direction. The structure of the needle-shaped electrodes in the second needle-shaped electrode array 26 is the same as that of the needle-shaped electrodes in the first needle-shaped electrode array 5.

[0061] In some embodiments of the present application, Figure 1 and Figure 4 As shown, a partition 16 is provided in the treatment chamber 4, and the partition 16 divides the treatment chamber 4 into a mixing chamber 41 and a reaction chamber 42.

The ozone in the second air pipe 15 and the sewage in the sewage chamber 2 both flow into the mixing chamber 41. A nozzle 161 is provided on the partition 16; an air pump 18 is provided on the first air pipe 14, and the air pump 18 is used to pump the gas outside the box 1 into the ozone chamber 13 and apply air pressure to the mixing chamber 41, so that the water in the mixing chamber 41 is sprayed into the reaction chamber 42 in the form of mist through the nozzle 161. With this structure, water entering from the inlet end of the treatment chamber 4 can be first stored in the mixing chamber 41. At this time, the air pump 18 can pump the gas outside the box body 1 into the ozone chamber 13 to form ozone, and the ozone flows into the mixing chamber 41 through the second air pipe 15 to purify the water in the mixing chamber 41. At the same time, the gas in the ozone chamber 13 can apply pressure to the mixing chamber 41, so that a high-pressure environment can be formed in the mixing chamber 41. After being pressurized, the water in the mixing chamber 41 can be sprayed from the nozzle 161 through the nozzle 161 into the reaction chamber 42 in the form of mist. Since the water in the mixing chamber 41 can have a better contact effect with the first needle-shaped electrode array 5 after being sprayed in the form of mist, the purification effect of the processor on sewage can be further improved, and then the purification effect of the sewage treatment device on sewage can be further improved.

[0065] In some embodiments of the present application, a third water level sensor 19 is provided at the upper portion of the mixing chamber 41, and the third water level sensor 19 is used to detect whether the water level in the mixing chamber 41 reaches a preset maximum water level; a third controller is also provided in the box body 1, and the water inlet pump 17 and the air pump 18 are both connected to the third controller. The third controller is used to control the water inlet pump 17 to work and the air pump 18 not to work when the third water level sensor 19 does not detect whether the water level in the mixing chamber 41 reaches the preset maximum water level, and to control the air pump 18 to work and the water inlet pump 17 not to work when the third water level sensor 19 detects whether the water level in the mixing chamber 41 reaches the preset maximum water level. With this structure, when the third water level sensor 19 does not detect whether the water level in the mixing chamber 41 has reached the preset maximum water level, it is still necessary to pump water into the mixing chamber 41 through the water inlet pump 17. At this time, the water inlet pump 17 is controlled to work and the air pump 18 is not controlled to work by the third controller, so that the water inlet pump 17 can pump water into the mixing chamber 41 and ozone will not be transported into the mixing chamber 41 to affect the pumping of water. When the third water level sensor 19 detects whether the water level in the mixing chamber 41 has reached the preset maximum water level, it is no longer necessary to pump water into the mixing chamber 41. At this time, the third controller controls the air pump 18 to work and the water inlet pump 17 to stop working, so that the water inlet pump 17 can stop pumping water into the mixing chamber 41, and the air pump 18 can pump gas into the ozone chamber 13. The gas can form ozone through the ozone chamber 13 and be transported to the mixing chamber 41 to sterilize and purify the water in the mixing chamber 41 and pressurize the mixing chamber 41, so that the water in the mixing chamber 41 can be sprayed out by the nozzle 161 under a high pressure environment.

[0066] In some embodiments of the present application, the third water level sensor 19 is a device capable of converting the measured water level signal into an electrical signal in real time, such as a piezoelectric water level sensor, a capacitive water level sensor, etc. The third water level sensor 19 is installed at the upper opening of the mixing chamber 41 .

[0067] In some embodiments of the present application, the first controller, the second controller, and the third controller may be three different controllers or may be the same controller.

[0068] In some embodiments of the present application, a vent pipe 20 for balancing the internal and external air pressure is provided on the side wall of the reaction chamber 42; the vent pipe 20 includes an inclined section and a vertical section, one end of the inclined section is connected to the side wall of the reaction chamber 42, and the other end is offset toward the side away from the water purification chamber 3, and one end of the vertical section is connected to the inclined section, and the other end extends toward the side away from the water purification chamber 3. With this structure, the reaction chamber 42 is connected to the atmosphere outside the housing 1 through the vent pipe 20, which can keep the pressure in the reaction chamber 42 balanced, and avoid the imbalance of the air pressure in the reaction chamber 42 and affect the normal operation of the sewage treatment device. Among them, when the vent pipe 20 includes an inclined section and a vertical section, it can prevent the water in the reaction chamber 42 from overflowing from the vent pipe 20.

[0069] In some embodiments of the present application, a cooling pipeline 21 is further provided in the housing 1. The cooling pipeline 21 is provided on the outer surface of at least one of the ozone chamber 13 and the treatment chamber 4. The first needle electrode array 5 is provided on the inner surface of the treatment chamber 4. The second needle electrode array 26 is provided on the inner surface of the ozone chamber 13. The inlet and outlet ends of the cooling pipeline 21 are both connected to the clean water chamber 3. A cooling water pump 22 is provided on the cooling pipeline 21. The cooling water pump 22 is used to pump water in the clean water chamber 3 into the cooling pipeline 21. With this structure, cooling water is pumped into the cooling pipeline 21 by the cooling water pump 22. When the cooling water flows through the outer surfaces of the ozone chamber 13 and the treatment chamber 4 through the cooling pipeline 21, the ozone chamber 13 and the treatment chamber 4 can be cooled and lowered to prevent the second needle electrode array 26 in the ozone chamber 13 and the first needle electrode array 5 in the treatment chamber 4 from failing due to high temperature. The residual ozone in the purified water can also be decomposed into oxygen to improve the purification effect of the water.

[0070] In some embodiments of the present application, the side walls of the ozone chamber 13 and the treatment chamber 4 may be metal cavity side walls, and the cavity structure within the metal cavity side walls may form a cooling pipeline 21 for circulating cooling water.

[0071] In some embodiments of the present application, a water outlet valve 24 is further provided on the water purification chamber 3 , and the water in the water purification chamber 3 can flow out through the water outlet valve 24 , and a filter net is provided on the water outlet valve 24 .

[0072] In some embodiments of the present application, a power module 25 is also provided in the box body 1, and the power module 25 is connected to an external power supply. The power module 25 can provide power for components such as the pulse power supply 6, the water inlet pump 17, the cooling water pump 22, and the air pump 18.

[0073] In some embodiments of the present application, the use process of the sewage treatment device is as follows:

[0074] First, before starting the sewage treatment device, connect the power module 25 of the sewage treatment device to a 220V external power supply, then place the external connecting pipe of the water inlet valve 23 in the sewage chamber 2 into the external sewage, and open the ventilation pipe 20 and the air inlet hole 27.

[0075] Secondly, turn on the switch of the power module 25 and check whether the power indicator light is on normally. According to the pollution of the water body to be purified, adjust the voltage, frequency and duration of the pulse power supply 6, and start the equipment after confirming that it is correct.

[0076] After that, the water inlet pump 17 is controlled to start working, and the sewage outside the box body 1 is pumped into the sewage chamber 2 through the water inlet pump 17. When the second water level sensor 12 detects that the sewage water level line in the sewage chamber 2 reaches the highest water level, the water inlet valve 23 is controlled to close. Then the valve 10 is controlled to operate to connect the first pipeline 7 and the second pipeline 8, and the sewage in the sewage chamber 2 is pumped into the mixing chamber 41 through the water inlet pump 17. When the first water level sensor 11 detects that the sewage water level line in the sewage chamber 2 reaches the lowest water level, the valve 10 is controlled to operate to connect the first pipeline 7 and the third pipeline 9.

[0077] Afterwards, when the third water level sensor 19 detects that the water level line of the water body in the mixing chamber 41 reaches the highest water level, the water inlet pump 17 is controlled to stop working and the air pump 18 is controlled to start working. When the air pump 18 is working, the air pump 18 is pumped into the ozone chamber 13, and the oxygen in the air is discharged through the second needle electrode array 26 in the ozone chamber 13 to generate ozone. The ozone flows into the mixing chamber 41 through the second air pipe 15 for purification. At the same time, the air pump 18 pumps in gas and cooperates with the nozzle 161, so that the water body in the mixing chamber 41 is sprayed into the reaction chamber 42 through the nozzle 161 in the form of mist. When the water level in the mixing chamber 41 is lowered, the water inlet pump 17 continues to work. When the mist sewage enters the reaction chamber 42, the effective purification of pollutants such as bacteria and organic matter in the sewage is achieved through the mixing effect of the pulse electric field and the ozone gas, and the purified water flows into the water purification chamber 3.

[0078] Afterwards, the water in the clean water chamber 3 is pumped into the mixing chamber by the water inlet pump 17, and the above steps are repeated until the water in the clean water chamber 3 meets the purification requirements.

[0079] Afterwards, the cooling water pump 22 is started, and the water in the water purification chamber 3 is pumped into the side wall cavity of the ozone chamber 13 and the treatment chamber 4 through the cooling water pump 22, so as to cool the first needle electrode array 5 and the second needle electrode array 26, and at the same time, the residual ozone in the purified water can be decomposed into oxygen.

[0080] Finally, the water in the water purification chamber 3 is discharged from the water outlet valve 24 to complete the purification of the sewage.
