Description

A reclaimed water utilization device for water resource management Technical Field

[0001] This invention belongs to the field of water resource utilization technology and relates to a reclaimed water utilization device for water resource management. Background Technology

[0002] Water scarcity has become a key bottleneck restricting global sustainable development, and the use of reclaimed water is considered a core approach to alleviate this crisis. However, many rivers currently suffer from severe contamination due to the long-term reception of inadequately treated industrial wastewater, domestic sewage, and agricultural non-point source pollution. This pollution, characterized by persistent organic matter, nitrogen and phosphorus nutrients, heavy metals, and antibiotics, results in widespread water quality deterioration to levels below Grade V or even black and odorous conditions. This not only damages river ecosystems but also renders rivers, which could have served as potential water sources, completely unusable for industrial cooling, urban miscellaneous uses, or landscape replenishment.

[0003] While existing wastewater treatment technologies are relatively mature in point source pollution control, they have significant limitations when dealing with widespread, large-scale, and complex pollution in rivers. Traditional activated sludge processes and conventional advanced treatment processes have limited efficiency in removing trace amounts of toxic and harmful substances, making it difficult for effluent quality to meet high-quality reclaimed water standards. On the other hand, while in-situ remediation technologies such as constructed wetlands and ecological floating islands are eco-friendly, they generally suffer from drawbacks such as large land area requirements, low hydraulic load, long purification cycles, and significant susceptibility to climate and seasonal influences, failing to meet the demands for rapid and large-scale water resource regeneration.

[0004] More importantly, there is currently a lack of integrated technological solutions in the field that can efficiently, stably, and cost-effectively convert heavily polluted river water directly into high-quality reclaimed water. Existing technologies often struggle to balance treatment efficiency and operating costs, resulting in a large amount of substandard river water being "unusable despite being desirable," causing a huge waste of precious water resources. Summary of the Invention

[0005] The purpose of this invention is to provide a reclaimed water utilization device for water resource management, which uses a variety of stable water purification technologies to transform inferior river water into usable reclaimed water resources.

[0006] To address the aforementioned technical problems, this invention provides a reclaimed water utilization device for water resource management, comprising a U-shaped regeneration channel. A connecting strip is laterally arranged at the upper part of the U-shaped regeneration channel near its inlet end. Multiple blocking strips are arranged downwards from the connecting strip. A horizontal connecting plate is horizontally arranged along one side of the blocking strips within the U-shaped regeneration channel. Multiple connecting ropes are connected to the lower end of the horizontal connecting plate, and multiple biological fillers are arranged on each connecting rope. A biological floating bed is arranged above the horizontal connecting plate within the U-shaped regeneration channel. Multiple planting holes are formed downwards through the biological floating bed. Each planting hole contains a detachable planting cup, and each planting cup has an open lower end and a mesh-like sidewall.

[0007] By adopting the above technical solution, wastewater flows in from the inlet of the U-shaped regeneration channel. First, it is filtered by the connecting and blocking strips, where larger particles are blocked and fall into the collection tank formed by the baffles, thus achieving initial solid-liquid separation. Subsequently, the water continues to flow forward, contacting the biological packing material suspended under the horizontal connecting plate. These biological packing materials are covered with a large number of microorganisms, which can convert ammonia nitrogen in the wastewater into nitrite or nitrate through amination reactions, further reducing the pollutant concentration.

[0008] When the water flows to the bio-floating bed area, the roots of the plants inside the planting cups come into full contact with the wastewater, using the plants' absorption and adsorption properties to remove nutrients such as nitrogen and phosphorus from the water. At the same time, the vegetation provides a habitat for microorganisms, promoting their growth and reproduction and enhancing the purification effect. Furthermore, the detachable planting cup design facilitates replacement and maintenance, ensuring long-term stable operation of the equipment.

[0009] The present invention is further configured such that a blocking platform is provided in the U-shaped regeneration channel at a position away from the blocking strip on the horizontal connecting plate, and a plurality of titanium dioxide photocatalytic plates distributed along the length direction are provided above the blocking platform in the U-shaped regeneration channel.

[0010] The present invention is further configured such that the side of each titanium dioxide photocatalytic plate closest to the horizontal connecting plate is inclined downwards.

[0011] The present invention is further configured such that a baffle is formed at the bottom of the U-shaped regeneration channel on the side of the blocking strip away from the horizontal connecting plate, and the height of the baffle is lower than the height of the blocking strip.

[0012] The invention is further configured such that a plurality of connecting holes are provided through the horizontal connecting plate downwards, and a cross connecting strip is provided in each connecting hole, and each connecting rope is connected to the lower end of the corresponding cross connecting strip.

[0013] Compared with existing technologies, this invention has the following beneficial effects: First, through a multi-stage purification design, it significantly improves wastewater treatment efficiency. Firstly, the U-shaped regeneration channel optimizes the water flow path, extends the water's residence time within the equipment, and ensures that pollutants are fully degraded. The combined use of blocking strips and baffles not only achieves preliminary solid-liquid separation but also effectively prevents impurities from flowing back, further improving the purification effect.

[0014] Secondly, the synergistic effect of the biological filler and the plant root system enhances the system's ecological purification capacity. The microbial community attached to the surface of the biological filler can efficiently decompose organic pollutants, while the vegetation inside the planting cup removes nutrients such as nitrogen and phosphorus through absorption and adsorption, while providing a suitable growth environment for microorganisms, forming a virtuous cycle.

[0015] Thirdly, the introduction of the titanium dioxide photocatalytic plate adds advanced oxidation capabilities to the equipment. Its downward-sloping design increases the light-receiving area and improves photocatalytic efficiency, effectively degrading recalcitrant organic matter and trace amounts of toxic and harmful substances in the water, thereby significantly improving the quality of the effluent.

Detailed Implementation

[0018] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of a reclaimed water utilization device for water resource management proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention. The same or similar reference numerals in the drawings represent the same or similar parts.

[0019] Referring to Figures 1-3, an example of a reclaimed water utilization device for water resource management includes a U-shaped regeneration channel 1. A connecting strip 2 is horizontally arranged at the upper part of the U-shaped regeneration channel 1 near its inlet end. Multiple blocking strips 3 are arranged downwards from the connecting strip 2, forming a mesh between the blocking strips 3 for water flow. A baffle 4 is formed upwards at the bottom of the U-shaped regeneration channel 1 on the side of the blocking strips 3 away from the horizontal connecting plate 5. The height of the baffle 4 is lower than the height of the blocking strips 3, and impurities filtered by the blocking strips 3 fall into the collection tank formed by the baffle 4. A horizontal connecting plate 5 is horizontally arranged on one side of the blocking strips 3 inside the U-shaped regeneration channel 1. Multiple connecting holes 6 are opened downwards through the horizontal connecting plate 5. Each connecting hole 6 contains a cross-shaped connecting strip 7, and the lower end of each cross-shaped connecting strip 7 is connected to a connecting rope 8. Multiple biological fillers 14 are arranged on each connecting rope 8, and an amination reaction is carried out through the biological fillers 14 to decompose ammonia nitrogen in the wastewater.

[0020] Inside the U-shaped regeneration channel 1, above the horizontal connecting plate 5, there is a bio-floating bed 9. Multiple planting holes 10 are opened through the bio-floating bed 9. Each planting hole 10 is equipped with a detachable planting cup 11. Each planting cup 11 has an open bottom and a mesh structure on the side wall. Vegetation is planted on the bio-floating bed 9 through the planting cup 11, and the vegetation is used to purify the sewage.

[0021] Inside the U-shaped regeneration channel 1, a baffle platform 12 is installed at a position away from the baffle strip 3 on the horizontal connecting plate 5. Above the baffle platform 12, multiple titanium dioxide photocatalytic plates 13 are arranged along the length of the channel. Each titanium dioxide photocatalytic plate 13 is inclined downwards on the side closest to the horizontal connecting plate 5. Under sunlight, the titanium dioxide photocatalytic plates 13 perform a photocatalytic reaction on the wastewater, purifying it.

[0022] Working principle: Wastewater flows in from the inlet of the U-shaped regeneration channel 1. It first passes through the filtration system of connecting strips 2 and blocking strips 3, where larger particles are blocked and fall into the collection tank formed by baffles 4, thus achieving initial solid-liquid separation. Subsequently, the water continues to flow forward, contacting the biological packing material 14 suspended below the horizontal connecting plate 5. These biological packing materials 14 have a large number of microorganisms attached to their surface, which can convert ammonia nitrogen in the wastewater into nitrite or nitrate through amination reactions, further reducing the pollutant concentration.

[0023] When the water flows to area 9 of the bio-floating bed, the roots of the vegetation in the planting cups 11 come into full contact with the wastewater, using the absorption and adsorption of the plants to remove nutrients such as nitrogen and phosphorus from the water. At the same time, the vegetation provides a habitat for microorganisms, promoting their growth and reproduction and enhancing the purification effect. Furthermore, the detachable design of the planting cups 11 facilitates replacement and maintenance, ensuring long-term stable operation of the equipment.

[0024] Next, the water flows through the baffle 12 into the active area of ​​the titanium dioxide photocatalytic plate 13. Under sunlight, the titanium dioxide photocatalytic plate 13 generates highly oxidizing free radicals, which can effectively decompose organic matter, antibiotics, and trace amounts of toxic and harmful substances in the wastewater. Since each photocatalytic plate is arranged at a downward angle, this not only increases the light-receiving area but also prevents suspended solids from accumulating on the plate surface, thus improving purification efficiency.

[0025] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0026] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
