[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model provides a technical solution: it includes a treatment tank 1, a sedimentation tank 2 at the top of the treatment tank 1, a filter tank 3 at the top of the treatment tank 1 and on one side of the sedimentation tank 2, filter plates 13 are fixedly connected at equal intervals inside the filter tank 3, a first detection device 14 is installed and connected inside each filter plate 13, a second detection device 15 is installed and connected to the bottom of the inner wall of the filter tank 3, a water pump 5 is fixedly installed and connected to the top of the treatment tank 1, a hose 6 is installed and connected to the input end of the water pump 5, a filter screen 4 is fixedly connected inside the sedimentation tank 2, one end of the hose 6 extends through the filter screen 4 into the interior of the sedimentation tank 2 and is fixedly connected to a water pump head 8, a spray pipe 11 is fixedly connected to the output end of the water pump 5, the spray pipe 11 is located above the filter tank 3, and nozzles 12 are fixedly connected at equal intervals to the bottom of the spray pipe 11.
[0026] In this embodiment, wastewater enters the sedimentation tank 2 at the top of the treatment tank 1. After sedimentation, the water pump 5 draws out the wastewater that has been initially filtered by the filter screen 4 in the sedimentation tank 2 through the hose 6 and the pump head 8. Then, the wastewater is evenly sprayed into the filter tank 3 through the spray pipe 11 and the nozzle 12. The filter plates 13 arranged at equal intervals inside are used for deep filtration. The first detection device 14 monitors the status of the filter plates 13, and the second detection device 15 detects the water quality at the bottom of the filter tank 3.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an air exchange hood 18 is fixedly connected to the outside of the treatment tank 1 and above the filter screen 4. An air exchange fan 19 is installed inside the air exchange hood 18. A cover plate 22 is fixedly connected to the top of the treatment tank 1. A photovoltaic panel 23 is installed on the top of the cover plate 22.
[0028] In this embodiment, the ventilation fan 19 inside the ventilation hood 18 operates to achieve air exchange between the inside of the treatment pool 1 and the outside; the photovoltaic panel 23 on the top of the cover plate 22 absorbs light energy and converts it into electrical energy.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a buoyancy ball 7 is fixedly connected to the outside of the hose 6 and above the pump head 8. Connecting rods 9 are fixedly connected at equal intervals to the bottom of the buoyancy ball 7. Contact plates 10 are fixedly connected between the bottoms of the multiple connecting rods 9 and below the pump head 8.
[0030] In this embodiment, the buoyancy ball 7 floats on the water surface, causing the pump head 8 to float with the water level. The contact plate 10 is connected to the buoyancy ball 7 through the connecting rod 9. When the contact plate 10 comes into contact with the sediment, it prevents the pump head 8 from extracting the sediment.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a first discharge pipe 16 is fixedly connected to one side of the treatment tank 1. The first discharge pipe 16 communicates with the inside of the filter tank 3. A second discharge pipe 17 is fixedly connected to the side of the treatment tank 1 away from the first discharge pipe 16. The second discharge pipe 17 communicates with the inside of the sedimentation tank 2. Valves are provided inside both the second discharge pipe 17 and the first discharge pipe 16.
[0032] In this embodiment, the treated water in the filter tank 3 that meets the standards is discharged from the first discharge pipe 16; the sediment in the sedimentation tank 2 that has been settled is discharged through the second discharge pipe 17.
[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a control panel 21 is installed on the outside of the treatment tank 1. Ventilation windows 20 are installed on both sides of the treatment tank 1 and above the filter screen 4. A filling pipe 24 is fixedly connected to one side of the treatment tank 1 and to the side of the ventilation window 20. The filling pipe 24 is connected to the inside of the sedimentation tank 2.
[0034] In this embodiment, the control panel 21 is used to control the operating parameters of the device and monitor the status of each component; the ventilation window 20 enables natural ventilation; and the filling pipe 24 introduces the wastewater to be treated into the sedimentation tank 2.
[0035] Working principle:
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, wastewater enters the sedimentation tank 2 at the top of treatment tank 1. If flocculant is needed to assist sedimentation, a predetermined amount of flocculant can be added through the injection pipe 24 before the wastewater enters the sedimentation tank 2 to accelerate the sedimentation of suspended particles in the wastewater. After sedimentation, the water pump 5 draws the wastewater that has been preliminarily filtered by the filter screen 4 from the sedimentation tank 2 through the hose 6 and the pump head 8. The power of the water pump 5 is matched with the photovoltaic panel 23 on the top of the cover plate 22. The photovoltaic panel 23 absorbs light energy, converts it into electrical energy, and stores it. The electrical energy required for the operation of the water pump 5 is preferentially obtained from the electrical energy converted and stored by the photovoltaic panel 23. Based on the power requirements of the water pump 5 and local sunlight conditions, the specifications and quantity of photovoltaic panels 23 are reasonably selected to ensure that the water pump 5 can operate normally while achieving efficient energy utilization and energy saving. Then, the sewage is evenly sprayed into the filter tank 3 through the spray pipe 11 and the nozzle 12, and deep filtration is performed by the filter plates 13 arranged at equal intervals inside. The first detection device 14 monitors the status of the filter plates 13, and the second detection device 15 detects the water quality at the bottom of the filter tank 3. When the first detection device 14 detects that the filter plates 13 have reached a certain degree of blockage, the control panel 21 issues an alarm to prompt that the filter plates 13 need to be cleaned. The cleaning method can be carried out by manually disassembling the filter plate 13. The ventilation fan 19 in the ventilation hood 18 is turned on to realize the air exchange between the inside of the treatment tank 1 and the outside. The photovoltaic panel 23 on the top of the cover plate 22 absorbs light energy and converts it into electrical energy. The buoyancy ball 7 floats on the water surface, driving the water pump head 8 to float with the water level. The contact plate 10 is connected to the buoyancy ball 7 through the connecting rod 9. When the contact plate 10 contacts the sediment, it prevents the water pump head 8 from extracting the sediment. The treated water in the filter tank 3 that meets the standards is discharged from the first discharge pipe 16. The sediment in the sedimentation tank 2 is discharged through the second discharge pipe 17. A sludge deposition area is naturally formed at the bottom of the sedimentation tank 2. The pipe opening of the second discharge pipe 17 is located near the bottom of the sedimentation tank 2. When sludge needs to be discharged, the manual control panel 21 pauses the water intake of the filling pipe 24 and the water pump 5 to ensure that the sedimentation tank 2 is in a static state. The manual valve in the second discharge pipe 17 is opened, and the sludge at the bottom is discharged with a small amount of sewage by gravity. The control panel 21 is used to control the operating parameters of the device and monitor the status of each component. The ventilation window 20 enables natural ventilation. The filling pipe 24 introduces the sewage to be treated into the sedimentation tank 2.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
