Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to an ecological purification system with micro-nano aeration. Background Technology

[0002] Water pollution refers to the phenomenon where pollutants entering a water body exceed its self-purification capacity, leading to changes in the water's chemical, physical, biological, or radioactive properties, thereby affecting the effective use of the water body, endangering human health, damaging the ecological environment, and causing water quality deterioration.

[0003] To address water pollution, ecological purification systems are an environmentally friendly and sustainable water purification technology that utilizes the self-regulating and self-purifying capabilities of organisms and ecosystems in nature to purify water. Through the metabolic activities of plants, microorganisms, and other organisms, organic pollutants in the water can be decomposed into harmless small molecules such as carbon dioxide and water, thereby achieving water purification.

[0004] Taking water purification through microbial metabolic activities as an example, these microorganisms typically attach to microbial packing materials to improve water quality. Microbial packing materials provide a habitat for microorganisms, and the biofilm formed on these materials stabilizes microbial activity within the system, enhancing its resistance to shocks and its self-purification capabilities. The microorganisms attached to the packing materials act as ecological regulators, catalyzing the degradation of pollutants through absorption, metabolism, and degradation. Simultaneously, microorganisms play a crucial role in the carbon and nitrogen cycles in water bodies. Through oxidation, reduction, photosynthesis, assimilation, and dissimilation, they can transform organic matter into simpler compounds and nitrogen into forms that can be absorbed and utilized by plants, thereby maintaining the balance of the aquatic ecosystem.

[0005] Microorganisms and microbial packing materials work synergistically to improve water quality. In long-term water purification, it is usually necessary to regularly check the integrity of the packing materials, the growth of the biofilm, and the water flow distribution, as well as periodically clean and repair damaged parts of the packing materials to maintain good purification effects. However, in existing ecological purification systems, inspecting the microbial packing materials is inconvenient. Utility Model Content

[0006] The purpose of this invention is to provide an ecological purification system with micro-nano aeration, which is convenient for regular inspection.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A micro-nano aeration ecological purification system, comprising:

[0009] A biological treatment unit includes a packing box and microbial packing material. The packing box has a packing receiving cavity inside, and the microbial packing material is filled in the packing receiving cavity. Aerobic microorganisms are attached to the microbial packing material.

[0010] A floating bed includes a support frame and a floating bed base plate. The support frame is fixedly connected above the floating bed base plate. The support frame has a passage space inside. A first through hole is opened at the top of the support frame. A second through hole is opened on the floating bed base plate. The first through hole, the passage space, and the second through hole are connected sequentially from top to bottom to form a channel for the filling loading box to pass through vertically. The upper part of the filling loading box is detachably locked and fixed to the floating bed base plate, and the lower part of the filling loading box extends through the second through hole to the bottom of the floating bed base plate.

[0011] The micro-nano aeration unit includes multiple aeration tubes, which are evenly arranged below the floating bed substrate and have multiple bubble outlets.

[0012] Furthermore, the upper part of the packing loading box extends outward to form a limiting boss, and a supporting step is provided on the upper side of the floating bed base plate. The supporting step is located outside the second through hole and is supported directly below the limiting boss.

[0013] Preferably, the microbial packing material is a spherical packing material.

[0014] Furthermore, a handle is fixedly provided on the packing loading box, and the handle is located at the top center of the packing loading box.

[0015] Furthermore, the support frame includes a horizontally arranged U-shaped frame and four vertically arranged columns. The columns are fixedly connected to the bottom of the U-shaped frame, and the positions of the columns correspond one-to-one with the corner positions of the U-shaped frame.

[0016] Furthermore, a cover plate is connected to the top of the support frame. The cover plate is hinged to the outside of the first through hole and can be rotated to close the first through hole.

[0017] Furthermore, a solar panel is hinged to the top of the support frame. The solar panel is electrically connected to the micro / nano aeration unit and can rotate to avoid the first through hole.

[0018] Furthermore, the aeration pipes are arranged around the outside of the second through hole, and all the aeration pipes are vertically arranged and equidistant.

[0019] This utility model has the following beneficial effects:

[0020] 1. The biological treatment unit uses a packing box as a carrier to load microbial packing material. The microbial packing material is covered with aerobic microorganisms that can degrade organic matter and remove pollutants. The entire packing box is set on the floating bed in a way that can be pulled up and down. It can be quickly pulled out and put into the floating bed during inspection, which greatly increases the convenience of inspection and maintenance of microbial packing material.

[0021] 2. In the micro-nano aeration unit, each aeration pipe surrounds the outside of the packing box, continuously outputting a large number of micro-nano bubbles to oxygenate the water, effectively increasing the dissolved oxygen content of the water, providing an ideal living environment for aerobic microorganisms, and enabling them to decompose organic pollutants in the water more efficiently.

[0022] 3. The floating bed is equipped with solar panels, which can directly or indirectly convert solar radiation energy into electrical energy, providing a stable and clean energy supply for the system. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-3 As shown, this utility model discloses an ecological purification system with micro-nano aeration, including a biological treatment unit 100, a floating bed 200 and a micro-nano aeration unit 300.

[0030] The biological treatment unit 100 includes a packing box 110 and microbial packing material 120. The packing box 110 has a packing receiving cavity 111 inside, and the microbial packing material 120 fills the packing receiving cavity 111. The microbial packing material 120 has a rich porous structure, providing ample living space for microorganisms and allowing aerobic microorganisms to attach. Through the aerobic microorganisms attached to the microbial packing material 120, organic matter can be degraded, pollutants such as nitrogen and phosphorus can be removed, effectively purifying the water and improving the living environment of aquatic organisms.

[0031] The floating bed 200 includes a support frame 210 and a floating bed base plate 220 that can float on the surface of water. The support frame 210 is fixedly connected to the top of the floating bed base plate 220. The support frame 210 has a passage space 211 inside. A first through hole 212 is opened at the top of the support frame 210, and a second through hole 221 is opened on the floating bed base plate 220, located directly below the first through hole 212. The first through hole 212, the passage space 211, and the second through hole 221 are connected sequentially from top to bottom to form a channel for the packing loading box 110 to pass through vertically. The upper part of the packing loading box 110 is detachably engaged and fixed to the floating bed base plate 220, and the lower part of the packing loading box 110 extends through the second through hole 221 to the bottom of the floating bed base plate 220. In other words, the entire packing loading box 110 is set on the floating bed 200 in a way that can be pulled up and down, so that it can be quickly pulled out and loaded into the floating bed 200 during maintenance, which greatly increases the convenience of inspection and maintenance of the microbial packing 120.

[0032] The micro / nano aeration unit 300 includes multiple aeration pipes 310, a gas-liquid mixing pump, a micro / nano bubble generator, and other structures not shown. The aeration pipes 310 are evenly arranged below the floating bed substrate 220, and each aeration pipe 310 has multiple bubble outlets 311. This micro / nano aeration unit 300 can generate micro / nano bubbles with diameters ranging from tens of nanometers to several micrometers. These generated micro / nano bubbles enter the water body through the bubble outlets 311 on the aeration pipes 310, effectively increasing the dissolved oxygen content of the water and providing an ideal living environment for aerobic microorganisms, enabling them to decompose organic pollutants in the water more efficiently. Compared to traditional aeration methods, it has higher oxygen mass transfer efficiency, longer bubble residence time, and better ecological benefits.

[0033] More specifically, the aforementioned microbial packing material 120 is preferably spherical. The spherical microbial packing material 120 not only improves water flow distribution but also has a larger specific surface area, providing ample growth space and increasing the amount of microorganisms attached. This efficient microbial attachment capability allows the spherical microbial packing material 120 to quickly form a biofilm in wastewater treatment, improving treatment efficiency. Furthermore, due to the spherical structure, gaps are formed between the filled microbial packing materials 120, allowing aeration airflow to quickly enter the packing loading box 110, improving the aeration uniformity within the packing loading box 110 and contributing to increased microbial degradation efficiency.

[0034] Meanwhile, the aeration pipes 310 located below the floating bed substrate 220 are arranged around the outside of the second through hole 221. Each aeration pipe 310 is vertically arranged and equidistant, which can further distribute air or oxygen to the entire water body in a relatively uniform manner, avoiding local over-aeration or under-aeration.

[0035] The upper part of the packing loading box 110 extends outward to form a limiting boss 112. A supporting step 222 is provided on the upper side of the floating bed base plate 220. The supporting step 222 is located outside the second through hole 221 and is supported directly below the limiting boss 112. Through the mutual cooperation of the limiting boss 112 and the supporting step 222, without the need for other fixing structures, the packing loading box 110 can be locked and fixed on the floating bed 200 at the same time it is placed in, making the installation and removal of the packing loading box 110 more convenient. A handle 113 is fixedly provided on the packing loading box 110. The handle 113 is located at the top center of the packing loading box 110, making it convenient for operators to lift the packing loading box 110.

[0036] A cover plate 215 is connected to the top of the support frame 210. The cover plate 215 is hinged to the outside of the first through hole 212. During maintenance, the first through hole 212 can be opened to allow the filling material loading box 110 to be placed or removed. During operation, it can be rotated to close the first through hole 212 to prevent debris from falling in. In addition to the cover plate 215, a solar panel 400 is also hinged to the top of the support frame 210. The solar panel 400 is electrically connected to the micro-nano aeration unit 300 and can directly or indirectly convert solar radiation energy into electrical energy, providing a stable and clean energy supply for the system. During system maintenance, it can also be rotated to avoid the first through hole 212, so as not to affect the placement or removal of the filling material loading box 110.

[0037] In this embodiment, the support frame 210 includes a horizontally arranged U-shaped frame 213 and four vertically arranged columns 214. The columns 214 are fixedly connected to the bottom of the U-shaped frame 213, and the positions of the columns 214 correspond one-to-one with the corner positions of the U-shaped frame 213. The entire support frame 210 has a simple structure and has a light weight while supporting other structures.

[0038] In summary, this ecological purification system is clean and environmentally friendly, and it provides rapid and even oxygenation, which helps to improve the purification rate. The system is also relatively easy to inspect and maintain regularly.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
