Description

Technical Field

[0001] This invention belongs to the field of soil ecological restoration technology, specifically relating to a soil ecological restoration device for targeted activation of microbial communities. Background Technology

[0002] With the rapid advancement of industrialization and agricultural modernization, soil pollution has become a major environmental challenge that urgently needs to be addressed globally. Heavy metal pollution, such as lead, cadmium, and mercury, as well as organic pollution, including pesticide residues, petroleum hydrocarbons, and polycyclic aromatic hydrocarbons, not only severely disrupt the ecological balance of soil, leading to decreased soil fertility and reduced biodiversity, but also pose a direct threat to the growth safety of crops through the cumulative effect of the food chain, thereby affecting human health and triggering a series of food safety and public health problems. Therefore, the research and application of soil ecological restoration technologies are particularly important and have become a research hotspot in the field of environmental science. Among the many soil remediation technologies, microbial remediation technology is widely used in soil pollution control due to its significant advantages such as environmental friendliness, cost-effectiveness, and no secondary pollution. The core of this technology lies in utilizing the metabolic activities of specific microbial communities to decompose pollutants in the soil into harmless or low-toxic substances or transform them into more stable forms through mechanisms such as biodegradation, biotransformation, or biofixation, thereby achieving soil purification and restoration of ecological functions. However, despite the many advantages of microbial remediation technology, existing technologies still face many challenges in practical applications.

[0003] Traditional microbial remediation methods often involve directly applying microbial agents to contaminated soil, aiming to accelerate pollutant degradation by increasing the number of effective functional bacteria in the soil. However, this method has significant drawbacks: firstly, the effective functional bacteria in the applied agents are often dormant or in a low-activity state, making it difficult for them to adapt quickly to the complex soil environment and exert their degradation effects; secondly, the lack of an effective activation mechanism results in weak colonization capacity and low metabolic efficiency of the bacteria, thus affecting the remediation effect, making the remediation process unstable, time-consuming, and costly. Furthermore, traditional methods struggle to achieve targeted activation of the target functional bacteria, meaning they cannot precisely control the activity state of the bacteria to meet the remediation needs of different pollution types and degrees.

The microbial activation component mounted on the mobile tray 1 includes a low-frequency pulse generator 31 (using an SG3525 chip as the control core, with an adjustable frequency range of 10-100Hz and an output voltage of 5-12V, which can be directly purchased from existing technologies) fixed on the top surface of the mobile tray 1 and located on one side of the microbial agent storage tank 21; a pulse electrode 32 installed inside the working gap 13 and connected to the low-frequency pulse generator 31 via a connecting wire; a substrate 33 detachably installed inside the working gap 13; and a light-activated LED light panel 34 fixed on the bottom surface of the substrate 33 (which can be directly purchased from existing technologies).

The stirring motor 212 is electrically connected to the central control module and can be periodically started to stir the microbial agent in the microbial agent storage tank 21 to prevent the microbial agent from settling and stratifying, and to ensure the uniformity of the microbial agent. The stirring motor 212 is specifically a micro geared motor, and mature products on the market can be directly purchased and used.

[0019] In this embodiment, preferably, the top of the bacterial agent storage tank 21 is also provided with an inlet 211 on the right side relative to the stirring motor 212, for subsequently replenishing the bacterial agent storage tank 21 with bacterial agent through the inlet 211.

[0021] In this embodiment, preferably, the frequency adjustable range of the low-frequency pulse generator 31 is 10-100Hz, and the light-activated LED light panel 34 can emit visible light with a wavelength of 400-600nm and infrared light with a wavelength of 660-730nm.

[0022] In this embodiment, preferably, a U-shaped connecting frame 11 is welded to the front end of the mobile bracket 1, and a connector 12 is fixed on the surface of the U-shaped connecting frame 11 for stable connection with the bracket behind the agricultural machinery. Two moving wheels 14 are installed on both sides of the mobile bracket 1.

[0023] In this embodiment, preferably, an electrode fixing block 321 for mounting the pulse electrode 32 is also fixed on the inner side of the working notch 13. The pulse electrode 32 moves through the electrode fixing block 321, and a locking bolt 322 for locking the pulse electrode 32 is threaded on the side of the electrode fixing block 321. The locking bolt 322 can be loosened by rotating counterclockwise to release the limitation on the pulse electrode 32, and then the pulse electrode 32 can be adjusted up and down. The pulse electrode 32 can be adjusted to a suitable working height according to actual needs. After adjusting to a suitable working height, the locking bolt 322 can be tightened again to fix it. The adjustment is very convenient.

[0024] In this embodiment, preferably, a disassembly and assembly structure 35 is also provided between the substrate 33 and the movable bracket 1. The disassembly and assembly structure 35 includes a threaded base rod 351 fixed to the end face of the substrate 33, a strip-shaped slide 352 opened on the side of the movable bracket 1 for the threaded base rod 351 to slide into, and a locking nut 353 sleeved on the surface of the threaded base rod 351 and locked to the side of the movable bracket 1, so as to realize the stable installation of the substrate 33 in the working notch 13.

[0026] In summary, when using this device, the first step is to set the microbial community type, agent dosage, and corresponding optimal activation parameters (pulse frequency, light wavelength) of the remediation area via a remote monitoring terminal. The mobile bracket 1 is then attached to the agricultural machinery, allowing the device to be towed behind it. The agricultural machinery is then activated, moving the device along the remediation path. The central control module, based on preset parameters, controls the quantitative delivery pump 22 to precisely deliver the agent, which is then evenly sprayed into the soil through the atomizing nozzle 25. Simultaneously, the central control module activates the low-frequency pulse generator 31 and the photoactivated LED light panel 34, releasing low-frequency pulse signals and specific wavelength light according to preset activation parameters to stimulate the sprayed microorganisms. The device performs targeted activation of the microbial community to enhance its activity. It moves continuously with the agricultural machinery, and the central control module monitors the amount of microbial community deployed and activation signal parameters in real time to ensure stable operation of all components. Workers can view operational data in real time via a remote monitoring terminal. If adjustments to activation parameters are needed, commands can be sent remotely, and the central control module automatically responds and adjusts the operating parameters of the low-frequency pulse generator 31 and the light-activated LED light panel 34 to ensure effective targeted activation. After completing the work in the preset repair area, workers send a stop command via the remote monitoring terminal. The central control module then stops all components, disconnects the mobile bracket 1 from the agricultural machinery, and completes the repair work.
