Description

Technical Field

[0001] This invention belongs to the field of river water purification technology, specifically relating to an in-situ river water purification device and method based on the synergistic and periodic operation of multi-media fillers. Background Technology

[0002] Urban rivers, especially those in northern regions, commonly suffer from poor self-purification capacity, complex pollutant composition (high proportion of recalcitrant COD), large temperature fluctuations, and frequent external shocks. Existing in-situ purification technologies, such as single-function artificial aeration, ecological floating beds, or contact oxidation, often have limitations, including limited purification effects, weak resistance to shocks, high energy consumption, or significant temperature dependence. Many devices operate in continuous flow mode, and their hydraulic conditions cannot simultaneously meet the varying reaction time requirements of multiple purification mechanisms, including physical, chemical, and biological methods, leading to insufficient purification and unstable results.

[0003] Therefore, there is an urgent need in this field for an in-situ water purification device and method that can integrate multiple purification mechanisms, operate flexibly, adapt to complex river environments, and is highly efficient and energy-saving. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A river in-situ water purification device based on multi-media packing synergy and periodic operation, comprising: The structural module includes a main frame and a floating structure, wherein the floating structure is disposed on the main frame and is used to support and float the device. A core reaction module is mounted on the floating structure. A photovoltaic power supply module, which is installed on the core reaction module, is used to provide power to the device; The auxiliary module includes an aeration mechanism that provides oxygen to the core reaction module and an anti-clogging mechanism that prevents water inlet blockage. A remote intelligent control module is connected to the core reaction module, the photovoltaic power supply module, the aeration mechanism, and the anti-clogging mechanism, respectively, and is used to monitor water quality parameters and control the operation of the device. Controlled by the remote intelligent control module, it operates in a periodic intermittent mode, with each operating cycle including a water intake period and a static reaction period.

[0005] Furthermore, the floating structure includes: A float system, which is mounted on the main frame and located at the bottom of the core reaction module, is used to make the device float on the water surface.

[0006] Furthermore, the core reaction module includes an equipment compartment, which is mounted on the floating plate system.

[0007] Furthermore, the photovoltaic power supply module includes: Multiple solar photovoltaic panels are installed on the top of the equipment compartment via a detachable steel frame structure and are evenly distributed along the circumference of the equipment compartment. An energy storage lithium battery is disposed inside the equipment compartment and connected to the solar photovoltaic panel.

[0008] Furthermore, the equipment compartment includes: A central water inlet chamber, located at the center of the float system; Multiple reaction tanks are installed on the float system and are evenly distributed along the circumference of the central inlet tank; the reaction tanks are filled with multi-media packing material. The anti-clogging mechanism is located at the inlet of the central water inlet chamber; the aeration mechanism is located inside the reaction silo.

[0009] Furthermore, the aeration mechanism includes a microporous aerator and / or aeration nozzle disposed in the reaction silo and an aeration pump disposed at the top of the central water inlet silo, the aeration pump being connected to the microporous aerator and / or aeration nozzle.

[0011] A method for in-situ river water purification based on multi-media packing synergy and periodic operation, employing the aforementioned in-situ river water purification device based on multi-media packing synergy and periodic operation, includes the following steps: S1: Deploy the device in the target water body and start it through the remote intelligent control module; S2: Control the device to operate according to a preset periodic intermittent operation mode, wherein each operation cycle includes a water intake period and a static reaction period in sequence; the duration of the static reaction period is longer than that of the water intake period; S3: During the water intake period, the water intake pump is started to pump the water to be treated into the core reaction module, and the aeration mechanism is started to perform aeration. S4: During the static reaction period, stop the water intake and / or adjust the aeration to allow the water to undergo a multi-stage synergistic purification reaction within the core reaction module; S5: The remote intelligent control module monitors water quality parameters in real time and dynamically adjusts operating cycle parameters, aeration intensity, or triggers maintenance commands based on the monitoring results.

[0012] Furthermore, the operating cycle also includes an aeration period located within the water inlet period and / or the static reaction period.

[0013] This invention forms a multi-stage purification chain of "oxidation-biochemistry-adsorption" for pollutants by synergistically arranging electrochemical functional fillers, biofilm carrier fillers and adsorption functional fillers in the core reaction module. This invention employs a periodic intermittent operation mode controlled by a remote intelligent control module (including an inlet water period and a static reaction period longer than the inlet water period), enabling different purification mechanisms to operate efficiently under their respective most suitable hydraulic conditions.

[0017] 4. Ecological safety and no secondary pollution: The core reaction relies on activating and strengthening the local microbial community. The filler system uses environmentally friendly materials, avoiding secondary ecological risks and chemical residues, and does not disrupt the original ecological balance.

[0018] 5. Intelligent management and optimized operation: The remote intelligent control module enables real-time online monitoring of water quality, intelligent adjustment of operating parameters, and fault early warning, realizing closed-loop intelligent operation and maintenance from "perception" to "control", which greatly improves management efficiency and the reliability of purification effect.
