Description

Technical Field

[0001] This invention belongs to the field of environmental engineering, and in particular relates to a wastewater treatment device for environmental engineering. Background Technology

[0002] In decentralized wastewater generation scenarios such as rural areas, independent guesthouses, and small campsites, the composition of wastewater is becoming increasingly complex. In addition to conventional organic matter, it commonly contains trace amounts of emerging pollutants such as anionic surfactants (e.g., LAS) from detergents and personal care products, as well as synthetic musk. These substances are chemically stable, and traditional small-scale biological treatment processes have limited removal efficiency, easily accumulating in the environment and posing long-term ecological risks. While adsorption can be an effective deep treatment method, small-scale adsorption devices suitable for these scenarios generally face core bottlenecks such as frequent replacement of the adsorption medium after saturation, difficulty in regeneration, or high energy consumption, leading to increased operating costs and a heavier management burden.

[0003] To reduce the energy consumption and maintenance requirements of the aforementioned distributed facilities, solar power has become the mainstream technology. Existing equipment typically uses fixed photovoltaic panels to provide power only to water pumps or controllers, achieving limited energy self-sufficiency. However, solar systems only play the role of a substitute "power source," resulting in low overall efficiency in solar energy utilization.

[0004] Although the field of materials science has developed intelligent adsorption materials such as temperature-sensitive polymer gels, which can undergo significant hydrophilic-hydrophobic switching around specific temperatures to achieve intelligent cycling of "low-temperature adsorption and high-temperature desorption," enabling low-energy regeneration, providing a significant challenge in engineering practice, especially for small-scale decentralized treatment units, is how to continuously, accurately, and cost-effectively provide the required periodic temperature-changing environment for these materials. Therefore, a wastewater treatment device for environmental engineering is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater treatment device for environmental engineering, which aims to solve the problems mentioned in the background art.

[0006] The present invention is implemented as follows: a wastewater treatment device for environmental engineering includes a horizontal reaction vessel, which is mounted by a support column located at its bottom, and further includes: A filling layer containing a temperature-sensitive polymer gel is provided, and the filling layer is located inside the horizontal reaction vessel; The photovoltaic module is mounted on the top of the horizontal reaction vessel via a bracket. The photovoltaic module includes two photovoltaic components that are slidably disposed on the top of the bracket. The two photovoltaic components can move synchronously and in opposite directions. A sensor array deployed on a horizontal reaction vessel and photovoltaic modules collects equipment data to control the operation of the photovoltaic modules. Specific steps include: The system status data, including water quality parameters, internal temperature of the reaction vessel, light intensity, and the location of photovoltaic components, are collected in real time through a sensor array. The system status data is compared with preset threshold conditions to determine and select whether to start the adsorption treatment mode or the material regeneration mode. The system generates corresponding control commands based on the selected mode to drive the two photovoltaic components to slide towards or away from each other. When the system status data meets the preset period completion conditions, a reset command that can reset the mode is generated.

[0007] Preferably, the sensor array includes a water quality sensor for monitoring water quality, a temperature sensor for monitoring the internal temperature of the horizontal reaction vessel, and a position sensor for monitoring the position of the photovoltaic components. The adsorption treatment mode is to control the sliding closure of the photovoltaic components to reduce the heating effect of light on the horizontal reaction vessel. The material regeneration mode involves controlling the photovoltaic components to slide open in order to enhance the heating effect of sunlight on the horizontal reaction vessel. The cycle completion conditions include the pollutant concentration monitored by the water quality sensor in the adsorption treatment mode decreasing to a preset standard value and the temperature monitored by the temperature sensor in the material regeneration mode remaining within the desorption required temperature range for a preset duration.

[0008] Preferably, the horizontal reaction vessel is provided with an inlet pipe and an outlet pipe, with the inlet pipe located on one side of its top and the outlet pipe located at its bottom. The horizontal reaction vessel is also provided with a maintenance door structure for replenishing or replacing the filling layer.

[0009] Preferably, the maintenance door structure includes a door body fixedly mounted on a horizontal reaction vessel, a sealing cover plate on the door body, an annular ring between the sealing cover plate and the door body, and a frame for installing a filling layer fixedly connected to the annular ring facing the inside of the horizontal reaction vessel. The frame is connected to the annular ring by multiple support rods.

[0010] Preferably, the annular ring has multiple positioning holes, and the door body is fixedly connected with pins that cooperate with the positioning holes.

[0011] Preferably, the top of the bracket is fixedly connected to two guide rail grooves, which are respectively placed on both sides of the horizontal reaction vessel and arranged along the length of the horizontal reaction vessel. The heights of the two guide rail grooves are different. The photovoltaic component includes a mounting plate that is slidably connected to the two guide rail grooves, and multiple photovoltaic panels are installed in the mounting plate.

[0012] Preferably, the bottom of the mounting plate is fixedly connected to two drive slides, which are respectively located in two guide rail grooves. The bottom of the mounting plate is also slidably connected to two support slides, which are respectively located in two guide rail grooves. When the two photovoltaic modules are in a closed state, the drive slide and support slide located in the same guide rail groove are located at both ends of the mounting plate.

[0013] The wastewater treatment equipment for environmental engineering provided in this embodiment of the invention has the following beneficial effects: This invention integrates a temperature-sensitive polymer gel with a smartly sliding photovoltaic component and utilizes a sensor array to achieve closed-loop control. It provides a solution for the efficient removal of emerging pollutants such as LAS and synthetic musk in decentralized wastewater treatment scenarios, offering both deep treatment and low-energy regeneration capabilities. By intelligently regulating the heat input to the horizontal reaction vessel through the sliding opening and closing of the photovoltaic component, it creates a periodically variable temperature environment for the temperature-sensitive gel, enabling "low-temperature adsorption and high-temperature desorption," thus significantly reducing adsorbent regeneration energy consumption. Simultaneously, the photovoltaic module continuously generates electricity while performing the core process function of auxiliary temperature control, achieving synergistic effects of solar energy in power supply and thermal management, breaking the limitation of solar energy as merely a substitute power source in traditional equipment. Therefore, it effectively overcomes the problems of difficult adsorbent regeneration, high energy consumption, and low overall solar energy utilization efficiency. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, an environmental engineering wastewater treatment device provided in one embodiment of the present invention includes a horizontal reaction vessel 1, which is mounted by a support column 2 located at its bottom, and further includes: A filling layer 3 is configured with a temperature-sensitive polymer gel, and the filling layer 3 is located inside the horizontal reaction vessel 1; Photovoltaic module 4 is mounted on the top of horizontal reaction vessel 1 via bracket 5. Photovoltaic module 4 includes two photovoltaic components 401 that are slidably disposed on the top of bracket 5. The two photovoltaic components 401 can move synchronously and in relative directions. A sensor array deployed on the horizontal reaction vessel 1 and the photovoltaic module 4 collects equipment data to control the operation of the photovoltaic module 4, such as... Figure 7 As shown, the specific steps include: S100 collects system status data in real time, including water quality parameters, internal temperature of the reaction vessel, light intensity, and the position of photovoltaic component 401, through a sensor array. S200 compares the system status data with preset threshold conditions to determine and select whether to start the adsorption treatment mode or the material regeneration mode. S300, generate corresponding control commands according to the selected mode to drive the two photovoltaic components 401 to slide towards or away from each other; S400: When the system status data meets the preset period completion conditions, a reset command is generated that can reset the mode.

[0019] In one embodiment of the present invention, the invention integrates a temperature-sensitive polymer gel with a smartly sliding photovoltaic component 401 and achieves closed-loop control using a sensor array. This provides a solution for the efficient removal of emerging pollutants such as LAS and synthetic musk in decentralized wastewater treatment scenarios, offering both deep treatment and low-energy regeneration capabilities. The sliding opening and closing of the photovoltaic component 401 intelligently regulates the heat input of solar irradiance to the horizontal reaction vessel 1, creating a periodically variable temperature environment for the temperature-sensitive gel required for "low-temperature adsorption and high-temperature desorption" at low cost, thereby significantly reducing the energy consumption for adsorbent regeneration. Simultaneously, the photovoltaic component 401 continuously generates electricity while performing the core process function of auxiliary temperature control, achieving synergistic effects of solar energy in power supply and thermal energy management, breaking the limitation of solar energy as merely a substitute power source in traditional equipment. Therefore, it effectively overcomes the problems of difficult adsorbent regeneration, high energy consumption, and low overall efficiency of solar energy utilization.

[0020] It should be noted that, compared with traditional temperature control methods that rely solely on external energy for heating or cooling, this invention creatively transforms the opening and closing motion of the photovoltaic component 401 into a photothermal management method. Its core feature is that the sliding of the photovoltaic panel 4012 is not the primary heat or cold source for reactor temperature control, but rather serves as a highly efficient auxiliary and optimization mechanism. When heating is required (e.g., material regeneration), the photovoltaic panel 4012 is opened to introduce sunlight for auxiliary heating, significantly reducing the energy consumption of the main heating system and shortening the heating time. When maintaining a low temperature is required (e.g., adsorption treatment), the photovoltaic panel 4012 is closed to provide shade, reducing additional heat load and significantly alleviating the burden on the cooling system. This allows the reactor to reach the precise temperature range required for the thermosensitive gel to operate more quickly and stably. This design cleverly utilizes solar energy to directly empower the core process, not only solving the problem of high regeneration energy consumption in traditional adsorption devices and the inconvenience of providing variable temperature environments for thermosensitive materials in small facilities, but also breaking through the limitation of existing solar wastewater treatment equipment that only uses photovoltaics for power generation. This temperature control method needs to be used in conjunction with conventional reaction vessel temperature control methods.

[0021] In one embodiment of the present invention, the sensor array includes a water quality sensor for monitoring water quality, a temperature sensor for monitoring the internal temperature of the horizontal reaction vessel 1, and a position sensor for monitoring the position of the photovoltaic component 401; the adsorption treatment mode controls the photovoltaic component 401 to slide closed to reduce the heating effect of light on the horizontal reaction vessel 1; the material regeneration mode controls the photovoltaic component 401 to slide open to enhance the heating effect of light on the horizontal reaction vessel 1; the cycle completion conditions include the pollutant concentration monitored by the water quality sensor in the adsorption treatment mode decreasing to a preset standard value and the temperature monitored by the temperature sensor in the material regeneration mode remaining within the desorption required temperature range for a preset duration.

[0022] like Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the horizontal reaction vessel 1 is provided with an inlet pipe 6 and an outlet pipe 7. The inlet pipe 6 is located on one side of its top, and the outlet pipe 7 is located at its bottom. The horizontal reaction vessel 1 is provided with a maintenance door structure 8, which is used to replenish or replace the filling layer 3.

[0023] In one embodiment, the maintenance door structure 8 includes a door body 801 fixedly mounted on the horizontal reaction vessel 1. A sealing cover plate 802 is provided on the door body 801, and an annular ring 9 is provided between the sealing cover plate 802 and the door body 801. A frame body 10 for installing the filling layer 3 is fixedly connected to the annular ring 9 facing inwards towards the horizontal reaction vessel 1. The frame body 10 is connected to the annular ring 9 by multiple support rods 11. Multiple positioning holes 12 are provided on the annular ring 9, and pins that mate with the positioning holes 12 are fixedly connected to the door body 801. The maintenance door structure 8 is key to facilitating the maintenance of the adsorbent. This structure includes a door body 801 fixed to the horizontal reaction vessel 1 and a sealing cover plate 802 fastened to the door body 801 by bolts. A rigid, porous frame body 10 accommodates the temperature-sensitive polymer gel and is directly connected to an annular ring 9 by multiple support rods 11. This annular ring 9 is a key component located between the sealing cover 802 and the door 801. Besides providing a seal, it also serves as a precise positioning and load-bearing interface. The annular ring 9 is made of dimensionally stable engineering plastic and has multiple positioning holes 12 machined onto it. When the maintenance door is closed, these positioning holes 12 precisely engage with corresponding pins fixed to the door 801, ensuring that the frame 10 and its internal adsorbent filling layer 3 are accurately and repeatedly positioned in the preset working position within the reactor each time. The filling layer 3 is composed of temperature-sensitive composite hydrogel particles with a defined low critical dissolution temperature and a poly(N-isopropylacrylamide) matrix, typically with a particle size of 2-5 mm, regularly packed within the porous frame 10. When the adsorbent performance deteriorates and needs replacement, the operator only needs to open the sealing cover 802 and then pull the entire adsorbent frame 10 module out of the reactor and replace it by holding or connecting the annular ring 9. This design modularizes the adsorbent, making replenishment or replacement extremely simple, requiring no complex disassembly or specialized tools, and significantly reducing the difficulty and cost of long-term equipment maintenance.

[0024] like Figure 3 and Figure 4As shown, in a preferred embodiment of the present invention, the top of the bracket 5 is fixedly connected to two guide rail grooves 13. The two guide rail grooves 13 are respectively placed on both sides of the horizontal reaction vessel 1 and arranged along the length direction of the horizontal reaction vessel 1. The heights of the two guide rail grooves 13 are different. The photovoltaic component 401 includes a mounting plate 4011 slidably connected to the two guide rail grooves 13. Multiple photovoltaic panels 4012 are installed in the mounting plate 4011.

[0025] In one embodiment, two drive slides 14 are fixedly connected to the bottom of the mounting plate 4011, and the two drive slides 14 are respectively located in two guide rail grooves 13. Two support slides 15 are also slidably connected to the bottom of the mounting plate 4011, and the two support slides 15 are respectively located in two guide rail grooves 13. When the two photovoltaic modules 4 are in a closed state, the drive slides 14 and support slides 15 located in the same guide rail groove 13 are located at opposite ends of the mounting plate 4011. The sliding mechanism at the top of the bracket 5 is the core mechanical structure for achieving stable and precise opening and closing of the photovoltaic components 401. The two guide rail grooves 13 are positioned on both sides along the length of the horizontal reaction vessel 1 and fixed to the bracket 5 at different heights, forming a defined inclined sliding plane. The key improvement is that a support slide 15 is pre-fixed in each guide rail groove 13. The support slide 15 is an independent, fixed load-bearing component. Its top has a groove or track, and it is internally embedded with a low-friction coefficient wear-resistant material or ball bearings. Its core function is to provide a stable and smooth sliding support surface for the moving components. The sliding of the mounting plate 4011 is achieved through two drive slides 14 fixedly connected to its bottom. Each drive slide 14 is a module integrating a power and transmission unit. Its outer shell is rigidly connected to the mounting plate 4011, and it contains a micro motor, a reducer, and a drive wheel. Its drive wheel falls precisely into the groove or track on the top of the fixed support slide 15. When the system issues a command, the motors in the two drive slides 14 start synchronously, and the drive wheel rolls on the fixed support slide 15, thereby precisely and smoothly driving the entire photovoltaic component 401 to slide along the guide rail. When the two photovoltaic components 401 need to close towards each other, their respective drive slides 14 drive the mounting plate 4011 to move towards each other; conversely, they move away from each other. The fixed design of the support slide 15 ensures the stability of load bearing and guidance, while the active drive of the drive slide 14 provides controllable movement. The two work together to realize the reliable movement of the photovoltaic component 401 between two preset positions of fully open and fully closed, so as to perform its auxiliary temperature control function.
