[0062] The present invention provides an integrated device for quantitative and precise dredging and monitoring of contaminated sediment, which can realize automated and integrated precise dredging detection, and can ensure more efficient quantitative and precise dredging and detection of contaminated sediment.

[0063] See Figures 1 to 5 , this embodiment provides an integrated device for quantitative and precise dredging and monitoring of polluted sediment, including a sediment suction module 1, a sediment identification module 2, a sediment treatment module 3 and an in-situ dosing module 4;

[0064] The sediment suction module 1 includes a suction pipe 11, a flushing pipe 12, a suction box 13 and a first drive assembly 14. The suction pipe 11 and the flushing pipe 12 are respectively connected to the suction box 13. The first drive assembly 14 is arranged on the suction box 13. The first drive assembly 14 is used to drive the suction box 13 and the suction pipe 11 and the flushing pipe 12 to move in the water. The flushing pipe 12 is used to emit a high-pressure water column to spray to the river bottom, so that the bottom sediment of the river bottom is stirred upward. The opening of the suction pipe 11 is set toward the output end of the flushing pipe 12. The suction pipe 11 is used to extract the upwardly stirred bottom sediment. The suction box 13 is provided with an extraction pump body for pumping out the sewage containing bottom sediment extracted by the suction pipe 11 upward;

[0065] The sediment identification module 2 includes a first storage box 21 and a spectrometer 22. A first filter component 23 is provided in the first storage box 21. The first storage box 21 is used to place the sewage containing sediment pumped out by the suction box 13. The first filter component 23 is used to filter the sediment in the sewage. The spectrometer 22 is used to collect spectral information of the sediment filtered by the first filter component 23, and analyze the pollution category of the sediment based on the spectral information. The pollution categories include heavy metal pollutants, organic pollutants, nutrient pollutants, petroleum pollutants and other pollutants.

[0066] The sediment treatment module 3 includes a control unit 31, a distribution assembly, and a sediment treatment assembly. The control unit 31 is electrically connected to the distribution assembly and the spectrometer 22. The sediment treatment assembly includes a plurality of second storage tanks, each of which is used to treat sediment of a different pollution category. The distribution assembly includes a plurality of distribution pipelines, which are connected to the output end of the first storage tank 21, and each distribution pipeline is connected to a second storage tank. The control unit 31 is used to select a distribution pipeline and a second storage tank that are compatible with the pollution category to transport the sediment based on the analysis results of the spectrometer 22.

[0067] The in-situ dosing module 4 includes a plurality of in-situ dosing pipelines, each of which is used to dosing an in-situ treatment agent. The in-situ dosing pipelines are electrically connected to the control unit 31 .

[0068] In this embodiment, the sediment suction module 1 utilizes the synergistic effect of the suction pipe 11 and the flushing pipe 12 to drive the equipment to move in the water through the first drive component 14. The high-pressure water column emitted by the flushing pipe 12 stirs the riverbed sediment and makes it float. The suction pipe 11 then extracts the sediment, and the extraction pump body pumps the sewage containing the sediment into the suction box 13; wherein, the suction pipe 11 is a pipe for sucking the sediment that floats upward after the riverbed is stirred into the equipment, and the flushing pipe 12 is a pipe for spraying high-pressure water columns onto the riverbed to stir the sediment and make it float. The suction box 13 is a box that accommodates the suction pipe 11 and the flushing pipe 12, and is provided with an extraction pump body inside for pumping out the sewage containing the sediment upward. The extraction pump body can be realized by using an electric motor drive device, a hydraulic drive device, a mechanical swing device, etc. The first drive component 14 is installed on the suction box 13, and is a device for driving the suction box 13 and the suction pipe 11 and the flushing pipe 12 to move in the water, such as a motor, a propeller, etc.

[0069] In this embodiment, the sewage containing sediment pumped out by the suction box 13 enters the first storage box 21, the first filter component 23 separates the sediment from the sewage, and the spectrometer 22 collects spectral information of the sediment, and accurately identifies the pollution type in the sediment, such as heavy metals, organic matter, etc. through spectral analysis technology; wherein, the first storage box 21 is a container for temporarily storing the sewage containing sediment pumped out by the suction box 13, and the spectrometer 22 is an instrument that uses spectral analysis technology to detect the composition of substances, and is used to collect spectral information of the sediment and then analyze its pollution type. Different types of spectrometers 22 can be selected according to needs. The first filter component 23 is a filtering device installed in the first storage box 21, which is used to separate the sediment from the sewage, such as a filter net, a filter membrane, etc.

[0070] In this embodiment, after receiving the analysis results of the spectrometer 22, the control unit 31 in the sediment treatment module 3 intelligently selects the distribution pipeline and the second storage tank that are compatible with the pollution category, and transports the sediment to the corresponding treatment unit. For example, heavy metal contaminated sediment is sent to a special heavy metal treatment storage tank, and organic pollutant sediment enters an organic pollutant treatment storage tank. The second storage tank is equipped with corresponding treatment processes and equipment, such as heavy metal precipitants, microbial degradation systems, etc., to achieve targeted treatment of sediments of different pollution categories; wherein, the control unit 31 is connected to the distribution component and the spectrometer The central control device electrically connected to 22 is responsible for receiving the analysis results of the spectrometer 22 and selecting the distribution pipeline and the second storage tank that are suitable for the pollution category according to the results to transport the sediment. The distribution component includes multiple distribution pipelines, and the multiple distribution pipelines are connected to the output end of the first storage tank 21. Each distribution pipeline is connected to a second storage tank and is used to distribute the sediment to the corresponding treatment storage tank; the sediment treatment component is composed of multiple second storage tanks, each storage tank is used to treat sediment of a pollution category, and is equipped with corresponding treatment processes and equipment, such as heavy metal precipitants, microbial degradation systems, etc.

[0071] In this embodiment, the in-situ dosing module 4, according to the instructions of the control unit 31, accurately adds the corresponding in-situ treatment agents, such as strong oxidants, adsorption materials, etc., into the water body or bottom mud through multiple in-situ dosing pipelines, thereby further promoting the degradation and removal of pollutants and improving the water environment at the same time; it can be understood that in-situ dosing refers to the process of dredging the bottom mud, according to the monitoring results, directly adding chemical agents or microbial preparations in situ (i.e., the location of the bottom mud), so as to promote the degradation or stabilization of pollutants in the bottom mud, avoid the diffusion and resuspension of pollutants, and reduce secondary pollution to the water body.

[0072] In this embodiment, the integrated equipment for quantitative and precise dredging and monitoring of contaminated sediment has significant beneficial effects. The efficient integrated design greatly improves the efficiency and accuracy of contaminated sediment treatment. Through the efficient suction of the sediment suction module 1 and the precise identification of the sediment identification module 2, the contaminated sediment can be quickly and accurately removed from the water body and classified, reducing the secondary pollution of the water body and the disturbance of non-contaminated sediment in the traditional dredging process, and reducing the treatment cost; the intelligent allocation and targeted treatment of the sediment treatment module 3 enable the sediment of different pollution categories to be effectively treated, improve the pollutant removal rate, and reduce the long-term harm of pollutants to the environment. For example, heavy metal contaminated sediment is removed through After special treatment, heavy metal ions are effectively precipitated or fixed, reducing their mobility and bioavailability in water bodies; organic pollutant sludge is decomposed into inorganic or less toxic substances through processes such as microbial degradation, reducing damage to aquatic ecosystems; the application of in-situ dosing module 4 further enhances the treatment effect of the equipment. By accurately adding in-situ treatment agents, it can accelerate the degradation process of pollutants, improve the self-purification capacity of water bodies, and promote the recovery of aquatic ecosystems. Overall, the equipment not only achieves efficient treatment of contaminated sludge, but also provides strong technical support for the restoration and protection of water environments. It has broad application prospects and important environmental protection significance.

[0073] See Figures 2 to 3 In some embodiments, the suction pipe 11 includes a first extension section 111, a second extension section 112 and an output pipe portion 113 that are connected in sequence. The diameter of the first extension section 111 gradually decreases along the axial direction of the first extension section 111 according to a first preset method, and the diameter of the second extension section 112 gradually decreases along the axial direction of the second extension section 112 according to a second preset method. The output pipe portion 113 is connected to the suction box 13. The bottom mud suction module 1 also includes a first guide plate group, including multiple first guide plates 114. The multiple first guide plates 114 are distributed at a first angle along the circumferential direction of the inner side wall of the first extension section 111. The first guide plate group is used to guide the bottom mud during the suction process.

[0074] In this embodiment, the suction pipe 11 is composed of a first extension section 111, a second extension section 112 and an output pipe section 113, wherein the diameters of the first extension section 111 and the second extension section 112 gradually decrease. The gradual decrease in the diameter of the first extension section 111 can quickly reduce the pressure in the pipe at the initial stage of suction, making it easier to suck in the bottom mud. The further reduction of the second extension section 112 helps to further accelerate the flow of the bottom mud before it enters the output pipe section 113, ensuring that the bottom mud can smoothly enter the suction box 13. In addition, the bottom mud suction module 1 also includes a first guide plate group, which is composed of a plurality of first guide plates 114. The plurality of first guide plates 114 are distributed at a first angle along the circumferential direction of the inner wall of the first extension section 111. During the process of the bottom mud being sucked, the first guide plate group plays a key guiding role, which can effectively guide the bottom mud to the vicinity of the center line of the suction pipe 11, reduce the diffusion and deposition of the bottom mud in the pipe, and thus improve suction. The first extension section 111 is the starting part of the suction pipe 11, and its diameter gradually decreases along the axial direction, which helps to increase the flow rate and make the bottom mud easier to be sucked in. The first preset method refers to the specific law or rate of diameter reduction. The second extension section 112 is immediately connected to the first extension section 111, and its diameter also gradually decreases along the axial direction, further increasing the flow rate and ensuring that the bottom mud smoothly enters the output pipe part 113. The second preset method also refers to the specific law or rate of diameter reduction. The output pipe part 113 is the end part of the suction pipe 11, which is connected to the suction box 13 to transport the sewage containing bottom mud to the suction box 13 for subsequent treatment. The first guide plate 114 is a plate-shaped structure for guiding the flow of bottom mud, which is installed on the inner wall of the suction pipe 11. Multiple first guide plates 114 are arranged at a certain angle along the circumference of the inner wall of the first extension section 111, which effectively guides the bottom mud during the suction process.

[0075] In this embodiment, the suction efficiency and accuracy of the contaminated sludge are improved. Through the gradually decreasing diameter design, the suction pipe 11 can form different negative pressures at different stages, ensuring that the sludge always maintains a high flow rate and stability in the process of entering the suction box 13, thereby reducing the risk of sludge deposition and clogging in the pipe; the setting of the first guide plate group effectively guides the flow of sludge, making it more concentrated, improving the transportation efficiency of sludge, while also reducing the disturbance to the water body, reducing the resuspension of pollutants, and helping to protect the water ecology.

[0076] See Figures 2 to 3 In some embodiments, the sediment suction module 1 further includes a second guide plate 115 , which is disposed on the inner side wall of the second extension section 112 . The second guide plate 115 extends spirally along the axial direction of the second extension section 112 , and the outer edge of the second guide plate 115 is wedge-shaped.

[0077] In this embodiment, in addition to the first guide plate assembly, a second guide plate 115 is also provided. The second guide plate 115 is located on the inner sidewall of the second extension section 112 and extends in a spiral shape along the axial direction of the second extension section 112. This spiral design applies a rotational force to the sediment before it enters the output pipe section 113, causing the sediment to form a spiral flow within the pipe. This spiral flow facilitates stable sediment transport within the pipe and reduces sediment deposition and clogging on the pipe wall. Furthermore, the outer edge of the second guide plate 115 is wedge-shaped. This wedge-shaped design allows the sediment to be more smoothly guided into a spiral flow upon entering the area of the second guide plate 115. The wedge-shaped edge effectively cuts and disperses sediment particles, preventing particle aggregation and clogging, further improving sediment transport efficiency. The spiral guidance and wedge-shaped cutting action of the second guide plate 115 ensures that the sediment is more evenly distributed within the pipe during the suction process, reducing water disturbance and the risk of pollutant resuspension. This also helps improve the treatment efficiency of the sediment by the subsequent treatment modules.

[0078] In this embodiment, the spiral second guide plate 115 can effectively guide the bottom mud to form a stable spiral flow. This flow mode not only improves the conveying efficiency of the bottom mud, but also reduces the risk of bottom mud deposition and clogging in the pipe, ensuring the continuity and stability of the suction process. The wedge-shaped outer edge design helps to cut and disperse the bottom mud particles and prevent particle aggregation, thereby further improving the conveying quality of the bottom mud, reducing the disturbance to the water body, reducing the re-suspension of pollutants, and is beneficial to protecting the water ecology.

[0079] See Figure 2 In some embodiments, the first drive assembly 14 includes a first drive unit 141, a first fan blade group 143, a first action wheel 144, and a second drive unit 142; the first drive unit 141 is arranged on the side of the suction box 13; the first fan blade group 143 includes a plurality of first fan blades, and the first fan blade group 143 is transmission-connected to the first drive unit 141; the first action wheel 144 is arranged at the bottom of the suction box 13, and the number of the first action wheels 144 is multiple and distributed along the circumference of the suction box 13; the number of the second drive units 142 corresponds to the number of the first action wheels 144, and each second drive unit 142 is transmission-connected to a first action wheel 144.

[0080] In this embodiment, the first drive assembly 14 can effectively realize the precise movement and positioning of the suction box 13 in the water. The first drive unit 141 is installed on the side of the suction box 13 and is responsible for providing the main power source. It drives the multiple first blades to rotate through the transmission connection with the first fan blade group 143. The rotation of the first fan blade group 143 can generate thrust in the water, so that the suction box 13 moves in the horizontal direction, thereby achieving precise positioning and coverage of the target area; wherein, the first drive unit 141 is usually a motor or other power source, which is responsible for providing power for the entire drive assembly, driving other components to move through the transmission connection, and driving the suction box 13 to move in the water. The first fan blade group 143 is a structure composed of multiple first fan blades, which is transmission connected to the first drive unit 141. The function of the first fan blade group 143 is similar to that of a propeller. When the first drive unit 141 is working, it drives the first fan blade group 143 to rotate, generating Thrust, pushing the suction box 13 forward or backward in the water to achieve horizontal movement; in addition, a plurality of first action wheels 144 are provided at the bottom of the suction box 13, and these action wheels are evenly distributed along the circumference of the box, which can provide stable support and mobility on the bottom of the water, and each first action wheel 144 is connected to a second drive unit 142 in transmission, and the number of the second drive units 142 corresponds to the number of the first action wheels 144, ensuring that each action wheel can be driven independently, so that the suction box 13 can move and turn flexibly on the bottom of the water to adapt to different underwater terrains and operation requirements; wherein, the second drive unit 142 is a drive device corresponding to the first action wheel 144, and the number is the same as the first action wheel 144. Each second drive unit 142 is connected to a first action wheel 144 in transmission, and is responsible for providing power to the first action wheel 144.

Hydrogen peroxide has a high redox potential and can effectively decompose organic pollutants, such as dyes, pesticide residues, etc., and convert them into inorganic substances or less toxic substances; during the dosing process, the in-situ dosing pipeline will evenly spray the hydrogen peroxide solution into the water body and bottom sediment to ensure that it fully contacts and reacts with the pollutants.

[0096] In other embodiments, the in-situ dosing pipeline is used to add natural organic materials such as rice husks and sawdust; rice husks and sawdust have rich pore structures and large specific surface areas, and can effectively adsorb heavy metal ions in water bodies and bottom sediments, such as lead, cadmium, etc., to reduce their concentration and bioavailability in the water body; when adding rice husks and sawdust, the in-situ dosing pipeline will adjust the position and method of addition according to the depth of the water body and the distribution of the bottom sediment to ensure that the rice husks and sawdust can be evenly distributed in the water body and bottom sediment, so as to give full play to their adsorption and bioremediation effects.

[0097] In this embodiment, the addition of a strong oxidant can efficiently remove organic pollutants in water bodies and bottom sediments, reduce the chemical oxygen demand (COD) and biological oxygen demand (BOD) of water bodies, improve the transparency and dissolved oxygen content of water bodies, and provide a better living environment for aquatic organisms; the addition of natural organic materials such as rice husks and sawdust can not only effectively remove heavy metal ions in water bodies and bottom sediments, reduce their toxic effects on aquatic organisms, but also promote the recovery and stability of water ecosystems; the addition of rice husks and sawdust provides rich nutrients and habitats for microorganisms in water bodies, enhances the biodegradation ability of microorganisms, and helps to build a healthy and balanced aquatic ecosystem; in addition, the in-situ addition method of this embodiment also has the advantages of simple operation and low cost.
