[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] To address the problems in the prior art, this utility model proposes a highly efficient water environment treatment pond for degrading pollutants, comprising:

[0030] A pool body 1, wherein the pool body 1 has a biodegradation zone 11 for decomposing pollutants through microbial action, and wherein at least one inlet channel 2 is provided on one side of the pool body 1; and

[0031] Aeration mechanism 3 is provided in the biodegradation zone 11 and is used to provide oxygen to the water to promote microbial metabolism.

[0032] Each of the inlet channels 2 is equipped with a crushing mechanism 5, which can pre-treat and crush the sewage to facilitate efficient degradation by microorganisms.

[0033] See also Figure 1 As shown, in this embodiment, the system structure consists of a tank 1, a biodegradation zone 11, an inlet channel 2, and an aeration mechanism 3. The tank 1 contains carrier materials such as porous ceramics, polyethylene suspended balls, or polyurethane foam, which provide an attachment platform for functional microorganisms such as nitrifying bacteria and denitrifying bacteria. The packing material is arranged in a stepped or honeycomb pattern to form an alternating anaerobic-aerobic microenvironment, thus constructing the biodegradation zone 11. These microorganisms can utilize organic matter in the water as an energy source, gradually decomposing it into simpler and harmless substances.

[0034] To ensure the life activities of microorganisms and the degradation of organic pollutants, an aeration mechanism 3 is installed in the biodegradation zone 11. This mechanism can be composed of a blower 33 or an air pump, which can continuously supply air to the tank, promoting the metabolic processes of microorganisms in the water. The generated bubbles not only help increase the concentration of dissolved oxygen in the water but also act as agitators, promoting water flow and the uniform distribution of pollutants.

[0035] In addition, in this embodiment, two inlet channels 2 are provided on one side of the pool body 1, both of which are used to introduce sewage into the biodegradation zone 11. To ensure that the water quality achieves the best degradation effect when passing through the biodegradation zone 11, a crushing mechanism 5 is provided in the inlet channel 2. This crushing mechanism 5 can be a mechanical crushing mechanism 5, a hydraulic crushing mechanism 5, an ultrasonic crushing mechanism 5, a high-pressure jet crushing mechanism 5, an airflow crushing mechanism 5, etc. Pre-treating the incoming sewage effectively reduces the particle size of solid matter in the sewage and increases the contact area between the sewage and microorganisms, thereby improving the degradation efficiency of pollutants. The water environment treatment pool of this application is suitable for treating water bodies containing a large amount of organic pollutants and solid matter, such as urban sewage, industrial wastewater, and agricultural wastewater. It can quickly and effectively reduce the concentration of pollutants in the water through efficient biodegradation and sufficient oxygen supply, thereby improving water quality.

[0036] In one possible implementation, the crushing mechanism 5 includes:

[0037] Multiple sets of crushing rollers 51, each of the crushing rollers 51 includes a rotating roller 511 and crushing teeth 512 disposed on the outer peripheral surface of the rotating roller 511 and arranged alternately;

[0038] The first drive motor 52 is connected to the crushing roller 51 for transmission.

[0039] Screening structure 53 is disposed downstream of crushing roller 51 to intercept incompletely crushed solids.

[0040] See also Figure 1 As shown, in this embodiment, the crushing mechanism 5 employs multiple sets of crushing rollers 51 working in tandem. Each set of crushing rollers 51 consists of a rotating roller 511 and circumferentially staggered crushing teeth 512. The gaps between adjacent crushing rollers 51 form a progressive compression and shearing space (the spacing is adjustable from 5 to 50 mm). The first drive motor 52 drives the crushing rollers 51 to rotate in opposite directions via a gearbox or chain drive. Solid pollutants in the wastewater are decomposed into fine particles under the squeezing and tearing action between the teeth. The downstream screening structure 53 is installed at an angle. Coarse particles that do not meet the standards are intercepted and returned to the crushing zone for recycling via a screw conveyor. Materials that meet the particle size requirements enter the biodegradation zone 11 with the water flow.

[0041] In one possible implementation, the aeration mechanism 3 includes:

[0042] Aeration pipe network 31 is laid inside the pool body 1;

[0043] Gas supply pipeline 32, the gas supply pipeline 32 being connected to the aeration pipeline network 31; and

[0044] A blower 33 is connected to the air supply pipeline 32 to supply air to the aeration network 31.

[0045] See also Figure 1 As shown, in this embodiment, the aeration mechanism 3 adopts a modular pipe network design, consisting of three parts: a blower 33, an air supply pipeline 32, and an aeration pipe network 31. The aeration pipe network 31 is a mesh layout composed of a main pipe (HDPE material) and branch pipes, with microporous aeration heads or swirling aerators evenly distributed on its surface to form a bubble cluster with a diameter of 1-3 mm. The pipe network is arranged in a ring or branch pattern, evenly distributed at different locations on the bottom or within the pool. The air distribution in each area is adjusted by an air distribution valve. The air supply pipeline 32 is responsible for transporting gas from the blower 33 to the aeration pipe network 31 within the pool body 1 to meet the aeration requirements.

[0046] In one possible implementation, the aeration mechanism 3 further includes a nanobubble generator 34 and an ozone generator 35, connected to the air supply pipeline 32 via a three-way valve. Specifically, in addition to the traditional blower 33 and aeration pipeline 31, the oxygen supply mechanism also includes a nanobubble generator 34 and an ozone generator 35, aiming to further increase the dissolved oxygen concentration in the pool 1 and improve water quality. The nanobubble generator 34 can generate tiny bubbles, converting air or oxygen into nano-sized bubbles with a higher surface area and stronger dissolving capacity, enabling them to dissolve rapidly in water, significantly increasing the dissolved oxygen level in the pool water, and promoting the self-purification capacity of the water body. The ozone generator 35 converts oxygen into ozone through an electrochemical reaction. The generated ozone has strong oxidizing properties and can be used for the oxidative degradation of harmful substances in the water, sterilization and disinfection, and removal of odors and organic pollutants from the water.

[0047] In one possible implementation, the pool body 1 is further provided with a stirring mechanism 4, the stirring mechanism 4 comprising:

[0048] Multiple rotating shafts 41 are arranged in parallel within the biodegradation zone 11;

[0049] Helical blade 42, the helical blade 42 being arranged helically along the axis of rotation 41, and

[0050] The second drive motor 43 is connected to the rotating shaft 41 via a transmission connection.

[0051] See also Figure 1As shown, in this embodiment, the stirring mechanism 4 adopts a multi-axis spiral synergistic stirring design, mainly composed of parallel rotating shafts 41, spiral blades 42, and a second drive motor 43. The rotating shafts 41 are spaced 1.0-2.5 meters apart and are laterally distributed in the lower layer of the biodegradation zone 11. The spiral blades 42 of adjacent rotating shafts 41 rotate in opposite directions (alternating clockwise and counterclockwise). The motor drives the rotating shafts 41 to rotate through a reducer. The edges of the spiral blades 42 are designed with a serrated structure to enhance the shear force of the fluid, thereby forming a dual flow state of vertical circulation and radial mixing. This design can effectively improve the mixing and flowability of the water and promote the uniform distribution of substances in the pool. In addition, the blade surface can be coated with an antibacterial coating to prevent biofilm adhesion and ensure long-term stable operation of the equipment.
