Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to a wastewater treatment device based on a photobioreactor of bacteria and algae. Background Technology

[0002] Wastewater treatment devices using algal-microbe photobioreactors utilize a symbiotic system for wastewater treatment. This type of device combines the photosynthetic capabilities of microorganisms and microalgae to efficiently treat pollutants such as organic matter, nitrogen, and phosphorus in wastewater. The algal-microbe symbiotic system fully utilizes light and the degradation capabilities of microorganisms to achieve efficient wastewater treatment. For example, a Chinese patent discloses an algal-microbe symbiotic phosphorus and nitrogen removal wastewater treatment device (application number CN202320976484.8). This device can automatically supplement light for algae, ensuring the normal growth of filamentous green algae. Combined with the adsorption effects of a primary clay-based ceramsite filter layer and a secondary modified sepiolite filter layer, it can effectively remove impurities from the water. Furthermore, a nanosheet membrane can retain organic matter and suspended solids, ensuring the purification effect of the wastewater. However, the lack of an automatic shading mechanism may lead to low light energy utilization and unstable microalgae growth conditions. The growth conditions of microalgae are affected by changes in external light, resulting in unstable growth and consequently affecting the wastewater treatment effect. Summary of the Invention

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a wastewater treatment device for bacterial and algal photobioreactor. When the external light source is too strong, the double-headed screw drives the telescopic plate to block the light on the top of the tank, and the rocker arm drives the baffle plate to cover the light-transmitting glass around the tank. Then, the internal light provides illumination, and the wastewater is further treated by the treatment cylinder to improve the wastewater treatment effect.

[0004] This utility model also provides a wastewater treatment device with the above-mentioned bacterial and algal photobioreactor, comprising: a base, on the upper surface of which a support frame, a treatment cylinder, and a housing are fixedly connected; a fixing frame is fixedly installed inside the housing, and a positioning frame is provided inside the fixing frame; two symmetrically arranged overlapping blocks are fixedly connected to the top of the support frame; each of the two overlapping blocks has a telescopic plate slidably connected inside; a double-ended screw is threadedly connected inside the two telescopic plates; the double-ended screw is rotatably connected to the outside of the overlapping block; a guide rod is fixedly slidably connected inside the two telescopic plates; and the end of the guide rod is fixedly connected to the overlapping block; two fixing seats are fixedly mounted on the two fixing seats. Mounted on the outside of the support frame, the fixed base is equipped with a protective mechanism. This mechanism includes two rockers, the ends of which are rotatably connected to the fixed base. The ends of the rockers away from the fixed base are slidably connected to a baffle plate via a sliding groove.

[0008] According to the wastewater treatment device based on the photobioreactor of bacteria and algae described in this utility model, a drain outlet is provided on the outside of the treatment cylinder, and a drain valve is provided at the connection between the drain outlet and the treatment cylinder.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-6 This utility model provides a wastewater treatment device for photobioreactor of bacteria and algae, which includes: a base 1, a support frame 5, a treatment cylinder 15 and a box 2 fixedly connected to the upper surface of the base 1, an inlet 24 provided on the outside of the box 2, a valve body 25 provided at the connection between the inlet 24 and the box 2, a light-transmitting glass 18 fixedly installed on the outside of the box 2, the light-transmitting glass 18 being located around the box 2, a fixing frame 3 fixedly installed inside the box 2, a positioning frame 4 provided inside the fixing frame 3, an installation frame 26 fixedly connected to the upper surface of the box 2, and a lamp body 28 fixedly installed inside the installation frame 26.

[0024] Specifically, the bacteria and algae are placed inside the fixed frame 3, and the lamp body 28 can provide the necessary light for the plants to promote their growth. Then, the sewage is transported to the inside of the box 2 by a water pump. At this time, the bacteria and algae rely on the adsorption and removal of organic matter and nutrients such as nitrogen and phosphorus in the water. The external light source will provide light for the photobiological reaction of bacteria and algae through the light-transmitting glass 18.

[0025] The top of the support frame 5 is fixedly connected to two symmetrically arranged overlapping blocks 6. Each of the two overlapping blocks 6 is slidably connected to a telescopic plate 7. The two telescopic plates 7 are threadedly connected to a double-ended screw 8. The outside of the double-ended screw 8 is rotatably connected to the overlapping block 6. The inside of the two telescopic plates 7 is fixedly slidably connected to a guide rod 9. The end of the guide rod 9 is fixedly connected to the overlapping block 6. There are two guide rods 9, which are symmetrically distributed and located on both sides of the double-ended screw 8.

[0026] Specifically, rotating the double-headed screw 8 drives the telescopic plate 7 to move, and causes the telescopic plate 7 to move linearly along the guide rod 9, thereby causing the plates inside the telescopic plate 7 to extend and retract outward one by one, thus covering the top of the box 2.

[0027] Two fixed seats 10 are fixedly installed on the outside of the support frame 5. The fixed seats 10 are equipped with protective mechanisms. There are four protective mechanisms distributed around the box 2. The box 2 is located below the telescopic plate 7. The protective mechanism includes two rocker arms 11. The ends of the two rocker arms 11 are rotatably connected to the fixed seats 10. The ends of the rocker arms 11 away from the fixed seats 10 are slidably connected to the baffle plate 13 through the slide groove 12. The baffle plate 13 is rotatably connected to the shaft 14. The end of the shaft 14 is fixedly connected to the fixed seats 10. The side surface of the fixed seats 10 is fixedly connected to the drive motor 27. The output end of the drive motor 27 is fixedly connected to the rocker arms 11. The upper surface of the base 1 is fixedly connected to the conveying pump 16. The input end of the conveying pump 16 is fixedly connected to the connecting pipe 17. The end of the connecting pipe 17 away from the conveying pump 16 is fixedly connected to the box 2. The output end of the conveying pump 16 is fixedly connected to the processing cylinder 15.

[0028] Specifically, starting the drive motor 27 drives the rocker arm 11 to cover the light-transmitting glass 18 around the box 2 with the shield 13, which can protect the plant from the effects of light inhibition. When the external light is too strong, the light energy absorbed by the plant may exceed the amount that its photosynthesis can utilize, resulting in a decrease in light energy conversion efficiency. Therefore, it is necessary to reduce the light energy absorbed by the plant by blocking some of the light.

[0029] An electrode plate 19 is provided at the bottom of the processing cylinder 15. A filter plate 20 and a collection plate 21 are provided inside the processing cylinder 15. The collection plate 21 is located below the filter plate 20. A drain outlet 22 is provided outside the processing cylinder 15. A drain valve 23 is provided at the connection between the drain outlet 22 and the processing cylinder 15.

[0030] Specifically, the electrode plate 19 is connected to an external power source to provide an electrochemical environment to promote the bioelectrochemical activity of bacteria and algae. It can decompose the remaining organic matter and remove nutrients in the water. The filter plate 20 can filter impurities in the water and the treated microalgae can be collected by the collection plate 21.

[0031] Working principle: First, the prepared bacteria and algae are placed inside the fixed frame 3. The water inlet 24 is connected to an external water pipe, and the valve 25 is opened. Then, the wastewater is pumped into the tank 2. At this time, the bacteria and algae adsorb and remove organic matter and nutrients such as nitrogen and phosphorus in the water. An external light source provides illumination for the photobiological reaction of the bacteria and algae through the translucent glass 18. When the external light source is too strong, the double-headed screw 8 is rotated to move the telescopic plate 7, thus covering the top of the tank 2. The drive motor 27 is started, driving the rocker arm 11 to cover the translucent glass 18 around the tank 2 with the shielding plate 13. Then, the light body 28 is turned on to illuminate the bacteria and algae. Photobiological reaction provides light to promote photosynthesis of microalgae, thereby accelerating the wastewater treatment process. After a period of time, the transfer pump 16 is started to transport the water inside the tank 2 to the inside of the treatment cylinder 15 through the connecting pipe 17. At the same time, the electrode plate 19 is connected to an external power source to provide an electrochemical environment to promote the bioelectrochemical reaction of bacteria and algae, which can decompose the remaining organic matter and remove nutrients in the water. The filter plate 20 can filter impurities in the water, and the treated microalgae are collected by the collection plate 21. After the treatment is completed, the drain valve 23 is opened so that the water inside the treatment cylinder 15 can flow out through the drain outlet 22.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
