Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a rural sewage microalgae treatment device. Background Art

[0002] Agricultural wastewater includes wastewater generated by livestock breeding. This type of wastewater is mainly composed of animal feces. Excess nitrogen and phosphorus in wastewater is one of the main causes of eutrophication of water bodies. Nitrogen and phosphorus are nutrients that can be used by microalgae, so microalgae can treat agricultural wastewater. Using microalgae treatment equipment to treat wastewater can not only reduce energy consumption, but also promote the recycling of nutrients such as nitrogen and phosphorus.

[0003] Existing wastewater microalgae treatment devices use a stirring rod to mix wastewater and algae. However, the presence of the stirring rod makes it impossible to set up a light source in the algae tank during use. When stirring, the stirring rod cannot evenly contact the light source with the algae at the bottom of the device, resulting in low mixing efficiency. At the same time, it also leads to insufficient light exposure to the algae in the device, which in turn reduces the photosynthesis of the algae and prevents the efficient utilization of nitrogen and phosphorus in the wastewater.

[0004] Therefore, a rural sewage microalgae treatment device is proposed to solve the above problems. Utility Model Content

[0011] Preferably, the surface of the bracket is provided with an arc-shaped groove matching the mixing pipe and the output pipe.

[0012] Preferably, the second lighting assembly includes a bracket, the bottom of the bracket is fixedly connected to the top of both ends of the bracket, and a plurality of LED light strips are fixedly connected between the brackets.

[0013] Preferably, the light emitting surface of the LED light strip is arranged toward the circulation component.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with a first lighting component and a second lighting component. When in use, the sewage in the algae box is illuminated by the LED light column.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-6 A rural sewage microalgae treatment device includes an algae box 1 and a peristaltic pump 2. A first illumination component is provided on the top of the algae box 1, a plurality of circulation ports 3 are opened on one side of the algae box 1, and a discharge port 4 is opened on the other side of the algae box 1. The circulation port 3 is fixedly connected with a circulation component, a bracket 5 is provided at the bottom of the circulation component, and a second illumination component is provided on the top of the bracket 5. The peristaltic pump 2 is located on one side of the circulation component and is connected to the circulation component, and a mixing component is provided in the circulation component.

[0026] Furthermore, the first lighting assembly includes a plurality of mounting plates 6, which are fixedly connected to both ends of the top of the algae box 1. A plurality of through holes are opened on the surface of the mounting plates 6, and LED lamp posts 7 are inserted into the through holes.

[0027] It should be noted that the length of the LED lamp column 7 is slightly smaller than the height of the algae box 1 .

[0028] A further advantage of adopting the above method is that the body of the LED lamp post 7 is located inside the algae box 1, so that the algae inside the algae box 1 can also be illuminated by the light, thereby improving the photosynthesis efficiency of the algae.

[0029] Furthermore, the circulation component includes a mixing pipe 8, the input end of the mixing pipe 8 is fixedly connected to the circulation port 3, the output end of the mixing pipe 8 is fixedly connected to the input end of the peristaltic pump 2, the output end of the peristaltic pump 2 is fixedly connected to an output pipe 9, and the output end of the output pipe 9 is fixedly connected to another circulation port 3. The length of the pipe is extended by bending the mixing pipe 8, thereby extending the mixing time of the sewage and making the mixing more uniform.

[0030] It should be noted that the mixing pipe 8 and the output pipe 9 are both configured as highly transparent acrylic tubes to improve the efficiency of light irradiation.

[0031] Furthermore, the mixing assembly includes a fixed ring 10 , which is fixedly installed inside the mixing pipe 8 , and a spiral blade 11 is fixedly connected to the inner wall of the fixed ring 10 .

[0032] A further advantage of adopting the above method is that when the mixed liquid flows through the spiral blades 11, the water flow is rotated under the action of the spiral blades 11, and the rotating water flow mixes the algae and sewage. Under the joint action of multiple mixing components, the sewage is fully mixed.

[0033] Furthermore, an arcuate groove 12 matching the mixing pipe 8 and the output pipe 9 is provided on the surface of the bracket 5 , and the mixing assembly is limited by the arcuate groove 12 .

[0034] Furthermore, the second lighting assembly includes a bracket 13 , the bottom of the bracket 13 is fixedly connected to the top of both ends of the bracket 5 , and a plurality of LED light strips 14 are fixedly connected between the brackets 13 .

[0035] A further benefit of adopting the above method is that, while mixing, the LED light strip 14 continuously illuminates the mixing assembly. Under the combined action of the rotating water flow and the LED light strip 14, the algae are fully exposed to the light, further improving the efficiency of photosynthesis.

[0036] When the present invention is in use, after sewage enters the algae box 1, suitable microalgae are poured into the algae box 1, and the LED lamp column 7 generates color light suitable for the microalgae, so that the algae inside the algae box 1 can be illuminated by the light, and then the peristaltic pump 2 is started. Under the action of the peristaltic pump 2, the sewage in the algae box 1 enters the mixing pipe 8 through one of the circulation ports 3, and the mixing time of the sewage is extended through the mixing pipe 8. When the sewage and microalgae flow through the spiral blades 11, the water flow is rotated under the guidance of the spiral blades 11, and the rotating water flow mixes the algae and sewage. Under the joint action of multiple mixing components, the sewage and algae are evenly and fully mixed. While mixing, the LED light bar 14 continuously illuminates the mixing component. Under the joint action of the rotating water flow and the LED light bar 14, the algae are fully exposed to the light and carry out photosynthesis;

[0037] After mixing, the mixed liquid is pumped back to the algae box 1 by the peristaltic pump 2 through the output pipe 9 to achieve a circulation effect, so that the sewage can be fully mixed, the efficiency of photosynthesis can be significantly improved, and the utilization efficiency of nitrogen and phosphorus elements in the sewage and the sewage treatment efficiency can be improved. The mixed liquid after treatment is discharged from the outlet 4 to complete the sewage treatment.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
