Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment ecological box based on Myriophyllum spicatum. Background Technology

[0002] Wastewater is a general term for water discharged during production and daily life activities. Water that has lost its original function is simply called wastewater. Wastewater is caused by the introduction of new substances into the water or by changes in external conditions, which cause the water to deteriorate and no longer maintain its original function. There are many types of wastewater, and correspondingly, there are many technologies and processes to reduce the impact of wastewater on the environment. Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] According to the search, for example, an ecological water purification tank proposed in publication number CN100371265C is a box structure with one or more partitions inside, and has an inlet and an outlet. A folding liquid flow path is formed between the inlet and the outlet by the partitions, and the box structure is filled with filler for water seepage.

[0004] The aforementioned patent documents describe a wastewater purification system achieved by filling the interior of the container with permeable packing material and providing a substrate to support plant growth and absorb organic matter. However, this system has drawbacks. As plants continuously absorb nutrients from the wastewater, algae proliferate, increasing in density and potentially causing their own death. Over time, this leads to a surge in nitrogen levels in the wastewater, creating an unsuitable environment for algae growth and significantly reducing the effectiveness of wastewater treatment. Therefore, a wastewater treatment eco-box based on *Myriophyllum spicatum* is urgently needed to address these issues. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the user can start the algae removal motor to rotate the algae removal worm. Since the algae removal worm is meshed with the algae removal worm wheel, the algae removal worm wheel can drive the bidirectional screw to rotate. The bidirectional screw is threadedly connected to the connecting block on the front side. Under the limiting constraint of the connecting block on the rear side by the limiting rod, the dividing plates on the left and right sides will move away simultaneously, causing the growth holes on the dividing plates to be misaligned. At this time, the dividing plates can cut off the longer green foxtail algae to prevent the excessive growth of green foxtail algae in the first, second and third treatment tanks, ensuring the purification effect of green foxtail algae on sewage. At the same time, the cut green foxtail algae stems and leaves can remain on the dividing plates for the user to clean up quickly and make into green fodder for preservation, improving the environmental friendliness of the entire device.

[0017] 2. In this invention, the user can start the drive motor to rotate the drive rod. Sprockets are fixedly installed on both the drive rod and the rear side of the outer wall of the reciprocating threaded groove rod. Under the action of the chain, the reciprocating threaded groove rod will rotate. A positioning sleeve is slidably installed on the outer wall of the reciprocating threaded groove rod and the drive rod. With the cooperation of the limiting pin in the inner cavity of the threaded groove wall on the reciprocating threaded groove rod, the sprayer plate can move back and forth at a uniform speed above the first treatment box. As the reciprocating threaded groove rod rotates continuously, the cam block fixed at its end also moves accordingly. Rotation, in conjunction with the return spring, lifts the squeezing rod, causing the pressure plate to move up and down reciprocally within the pressure accumulator box. When the volume of the upper cavity of the pressure accumulator box increases, fertilizer solution can be drawn from the storage box and enter the inner cavity of the pressure accumulator box through the inlet pipe. When the volume of the upper cavity of the pressure accumulator box decreases, the fertilizer solution in the upper cavity of the pressure accumulator box can enter the sprayer plate through the outlet pipe, and be evenly sprayed onto the green foxtail algae to supplement the trace elements lacking in the green foxtail algae, ensuring the healthy and robust growth of the green foxtail algae, and thus ensuring the quality of wastewater purification treatment in the entire ecological box.

[0029] It should be noted that, through the sewage inlet pipe 71, connecting pipe 72, and sewage outlet pipe 73, users can sequentially pass sewage through the first treatment tank 2, the second treatment tank 3, and the third treatment tank 4, achieving the goal of filling and replacing the sewage in the first treatment tank 2, the second treatment tank 3, and the third treatment tank 4 at any time. The container-like design of the entire unit facilitates the initial hoisting and transportation of the entire sewage treatment device. The through-flow design at both ends of the container ensures good ventilation in the first treatment tank 2, the second treatment tank 3, and the third treatment tank 4, allowing the *Myriophyllum spicatum* growing within them to thrive. The multiple sets of long-core laser lamps 11 ensure sufficient daily sunlight exposure for the *Myriophyllum spicatum*, effectively promoting root growth and absorbing organic nutrients from the sewage. This enables the entire ecological tank to purify the sewage. The photovoltaic solar panels 12 absorb solar energy and convert it into electricity to power the motors inside the container 1 and the long-core laser lamps 11, reducing user operating costs.

[0030] Furthermore, the algae removal component 8 includes supports 81 fixedly installed on the left and right sides of the front and rear end faces of the first treatment box 2, the second treatment box 3 and the third treatment box 4, and a bidirectional screw 82 rotatably installed in the inner cavity of the front support 81.

[0038] It should be noted that the user can start the drive motor 98 to rotate the drive rod 92. Sprockets 99 are fixedly installed on both the drive rod 92 and the rear side of the outer wall of the reciprocating threaded groove rod 91. With the cooperation of the chain 910, the reciprocating threaded groove rod 91 will rotate. A positioning sleeve 93 is slidably installed on the outer wall of the reciprocating threaded groove rod 91 and the drive rod 92. With the cooperation of the limiting pin 911 in the inner cavity of the threaded groove wall of the reciprocating threaded groove rod 91, the sprayer plate 94 can move back and forth at a uniform speed above the first treatment box 2. As the reciprocating threaded groove rod 91 rotates continuously, the cam block 912 fixed at its end also moves accordingly. Rotation, in conjunction with the return spring 916, lifts the squeezing rod 915, causing the pressure accumulator plate 914 to move up and down reciprocally within the pressure accumulator box 913. When the volume of the upper cavity of the pressure accumulator box 913 increases, fertilizer solution can be drawn from the storage box 917 and enter the inner cavity of the pressure accumulator box 913 through the water inlet pipe 918. When the volume of the upper cavity of the pressure accumulator box 913 decreases, the fertilizer solution in the upper cavity of the pressure accumulator box 913 can enter the sprayer plate 94 through the water outlet pipe 919 and be evenly sprayed onto the green foxtail algae to supplement the trace elements lacking in the green foxtail algae, ensuring the healthy and robust growth of the green foxtail algae, and thus ensuring the quality of wastewater purification treatment in the entire ecological box.

[0039] Working principle: Users can start the algae removal motor 88 to rotate the algae removal worm 86. Since the algae removal worm 86 is meshed with the algae removal worm wheel 87, the algae removal worm wheel 87 can drive the bidirectional screw 82 to rotate. The bidirectional screw 82 is threadedly connected to the front connecting block 89. Under the constraint of the limiting rod 83 on the rear connecting block 89, the left and right dividing plates 5 will move away simultaneously, causing the growth holes 51 on the dividing plates 5 to be misaligned. At this time, the dividing plates 5 can cut off the longer green foxtail algae to prevent the excessive growth of green foxtail algae in the first treatment tank 2, the second treatment tank 3 and the third treatment tank 4, ensuring the effect of green foxtail algae in purifying wastewater. At the same time, the cut green foxtail algae stems and leaves can remain on the dividing plates 5 for users to clean up quickly and make into green fodder for preservation, improving the environmental friendliness of the entire device.

[0040] The user can start the drive motor 98 to rotate the drive rod 92. A sprocket 99 is fixedly installed on both the drive rod 92 and the rear side of the outer wall of the reciprocating threaded groove rod 91. With the cooperation of the chain 910, the reciprocating threaded groove rod 91 will rotate. A positioning sleeve 93 is slidably installed on the outer wall of the reciprocating threaded groove rod 91 and the drive rod 92. With the cooperation of the limiting pin 911 in the inner cavity of the threaded groove wall of the reciprocating threaded groove rod 91, the sprayer plate 94 can move back and forth at a uniform speed above the first treatment box 2. As the reciprocating threaded groove rod 91 rotates continuously, the cam block 912 fixed at its end also rotates accordingly. With the help of the return spring 916, the squeezing rod 915 can be lifted, causing the pressure accumulator plate 914 to move up and down in the inner cavity of the pressure accumulator box 913. When the volume of the upper cavity of the pressure accumulator box 913 increases, fertilizer solution can be drawn from the liquid storage box 917 and enter the inner cavity of the pressure accumulator box 913 through the water inlet pipe 918. When the volume of the upper cavity of the pressure accumulator box 913 decreases, the fertilizer solution in the upper cavity of the pressure accumulator box 913 can enter the sprayer plate 94 through the water outlet pipe 919 and be evenly sprayed on the green foxtail algae to supplement the trace elements lacking in the green foxtail algae, ensuring the healthy and robust growth of the green foxtail algae, and thus ensuring the quality of wastewater purification treatment in the entire ecological box.

[0041] It should be noted that in the actual use of this eco-box, multiple treatment boxes can also be set horizontally at the bottom of the container 1. In this case, it is only necessary to change the connection position of the sewage inlet pipe 71, the connecting pipe 72 and the sewage outlet pipe 73 in a localized manner to ensure that the sewage can flow in the horizontally placed treatment box. At the same time, supplementary lights are set above the corresponding treatment boxes to ensure that the green foxtail algae in each horizontally placed treatment box can absorb and purify the sewage.

[0042] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
