Description

Technical Field

[0001] This utility model relates to the field of mud treatment technology, and in particular to a device for treating chemical additives in land reclamation mud. Background Technology

[0002] Land reclamation projects typically involve extensive filling operations, using dredged mud and waste mud as filling materials. This mud often contains large amounts of chemical additives (such as dispersants, flocculants, and solidifying agents). These additives are used in engineering to improve the fluidity, stability, and solidification properties of the mud, but their residues can pose a potential threat to the marine ecosystem. Currently, existing technologies for removing chemical additives from land reclamation mud mainly employ physical separation, chemical precipitation, and biodegradation. Physical separation methods typically involve using equipment such as centrifuges, filters, or settling tanks to separate solid particles from the liquid through physical forces. Chemical precipitation technology relies on adding specific chemical reagents to the mud to promote the formation of insoluble precipitates of harmful chemical additives, thereby achieving removal. Biodegradation processes utilize the metabolic activity of microorganisms to convert chemical additives into harmless or low-toxicity substances.

[0003] In recent years, peroxyorganic acids (such as peracetic acid and performic acid) have been increasingly introduced into the field of pollutant degradation due to their strong oxidizing properties and environmental friendliness. They are widely used in water treatment and soil remediation to degrade organic pollutants and emerging pollutants. In water treatment, peroxyorganic acids can efficiently degrade organic pollutants such as dyes, pesticides, and drug residues. In soil remediation, they also show good treatment effects on recalcitrant organic compounds such as petroleum hydrocarbons and polycyclic aromatic hydrocarbons. Compared with traditional oxidants, peroxyorganic acids have higher oxidation potentials, enabling them to rapidly degrade various organic pollutants, and their decomposition products are mainly water and carbon dioxide, without causing secondary pollution. However, there is limited research on the application of peroxyorganic acids in removing chemical additives from land reclamation mud.

[0004] The following technical problems exist in existing research on sludge treatment devices: (1) Physical separation methods, such as centrifuges or filtration equipment, can effectively remove some suspended solids from water. However, this method has limited effectiveness in removing chemical additives dissolved in water. In addition, although biodegradation is an environmentally friendly treatment method that decomposes pollutants through the action of microorganisms, this method has a relatively long treatment cycle and low treatment efficiency, making it difficult to meet the needs of rapid treatment of reclamation mud in land reclamation projects.

[0005] (2) Chemical oxidation has become one of the current research hotspots. In this field, strong oxidants such as hydrogen peroxide and potassium permanganate are widely used to degrade organic pollutants in water. Although these chemical oxidants show certain degradation capabilities under laboratory conditions, their oxidation capacity is often limited and their selectivity is poor in practical applications. In addition, these oxidants are not ideal for treating certain specific chemical auxiliaries, which limits their application in practical engineering.

[0006] (3) Peracetic acid (PAA) has been widely used as a disinfectant, bleaching agent, oxidant, and polymerization catalyst in food processing, aquaculture, medical, and textile industries. PAA can also effectively decompose sludge in complex processes, dissolving and destroying bacteria and extracellular polymers (EPS) in sludge flocs. In water treatment, PAA can remove more than 95% of organic pollutants; in soil remediation, its degradation efficiency for petroleum hydrocarbon pollutants exceeds 90%. However, there is limited research on the application of peracetic acid in removing chemical additives from land reclamation mud.

[0007] (4) During land reclamation projects, the mud is usually treated off-site, that is, the mud is treated in a place far away from the reclamation area, and then the treated mud is transported to the reclamation area for land reclamation construction. However, this treatment method has a potential problem, that is, secondary pollution may occur during the transportation of the mud. This is because the mud may leak or drip during transportation, thereby polluting the environment along the transportation route. Utility Model Content

[0020] Figure 1 This is a structural diagram of the device for treating chemical additives for land reclamation mud according to this utility model. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, this utility model discloses a treatment device for chemical additives in reclamation mud, comprising a mud filtration unit 1, a chemical adjustment unit 2, a storage unit 3 for storing pH or salinity adjusters, a mud storage unit 4, a reaction vessel 5, a dosing unit 6 for storing peroxy organic acids, a UV treatment unit 7, and a mud detection unit 8. The inlets of the mud filtration unit 1, chemical adjustment unit 2, mud storage unit 4, and reaction vessel 5 are connected in sequence. The storage unit 3 is connected to the chemical adjustment unit 2, and the dosing unit 6 is connected to the inlet of the reaction vessel 5. The outlet of the reaction vessel 5, the UV treatment unit 7, and the mud detection unit 8 are connected in sequence. The mud to be treated is input from the inlet 13 of the mud filtration unit 1 and transported into the reaction vessel 5. The peroxy organic acids are transported into the reaction vessel 5 through the dosing unit 6. The treated mud is output from the outlet of the reaction vessel 5 and transported to the outlet 82 of the mud detection unit 8 for discharge.

[0023] Slurry transportation: The pre-treated slurry is transported via a centrifugal pump and corrosion-resistant pipes, sequentially through slurry filtration unit 1 for physical filtration, and chemical conditioning unit 2 for chemical treatment, before being pumped to reaction vessel 5. The chemical storage unit 3 provides pH adjusters or salinity adjusters to the chemical conditioning unit 2 to regulate the slurry's pH and salinity, as needed for the chemical treatment process. During transportation, sensors are used to monitor the slurry's flow rate and pressure in real time to ensure its stability and continuity.

[0024] Delivery of peroxyorganic acids: The peroxyorganic acids are prepared in the preparation unit 6. The prepared peroxyorganic acid solution is then delivered to the reaction vessel 5 via a metering pump. Sensors are used to monitor the flow rate and pressure of the slurry in real time. Pipelines and pump bodies must be made of corrosion-resistant materials (such as stainless steel or polytetrafluoroethylene) to prevent corrosion from the peroxyorganic acids. During delivery, the amount of peroxyorganic acid added is monitored and precisely controlled in real time using a flow meter.

[0025] Transportation of treated sludge: After treatment with peroxy organic acid, the sludge in reaction vessel 5 is pumped to UV treatment unit 7 for further disinfection to completely kill pathogenic microorganisms and degrade residual organic pollutants. The disinfected sludge is then pumped to sludge testing unit 8 for temporary storage, where samples are taken for testing. Once the tests are passed, the sludge is discharged from outlet 82 of sludge testing unit 8, ensuring that the discharged sludge meets emission standards.

[0026] Before entering the core treatment stage, the slurry undergoes preliminary physical and chemical treatment to remove interfering substances and optimize its properties, ensuring the efficient operation of subsequent treatment processes. The physical treatment stage is carried out through a filtration unit, and the chemical conditioning stage is carried out through chemical conditioning unit 2.

[0027] The mud filtration unit 1 includes a filtration tank 11 and a multi-stage filtration assembly 12. The multi-stage filtration assembly 12 includes a coarse screen, a medium-fine screen, and a wire mesh filter, which are installed sequentially within the filtration tank 11 along the liquid flow direction. The mud is passed through the multi-stage filtration assembly 12, which consists of a 10mm coarse screen (for initial interception of construction waste, plastic bags, large debris, etc.), a 5mm medium-fine screen (for intercepting large sand particles, shell fragments, small plant stems and leaves, etc.), and a 1mm wire mesh filter (for removing coarse mud and sand and improving the uniformity of the suspended mud). The filtered mud has significantly improved fluidity, while reducing the risk of wear and clogging in subsequent treatment equipment. Solid waste generated during the filtration process must be collected centrally and properly disposed of to avoid secondary pollution.

[0028] The drug storage unit 3 includes a pH adjuster storage tank 31 and a salinity adjuster storage tank 32. The chemical adjustment unit 2 includes a chemical adjustment tank 21, a pH sensor, a conductivity meter, and a chemical adjustment stirrer 22. The pH adjuster storage tank 31 and the salinity adjuster storage tank 32 are respectively connected to the chemical adjustment tank 21. The pH sensor, conductivity meter, and chemical adjustment stirrer 22 are respectively installed in the chemical adjustment tank 21.

[0029] After physical treatment, the slurry's chemical properties are adjusted. First, a pH adjuster (such as sodium hydroxide, lime slurry, or sulfuric acid) is used to adjust the slurry's pH to a range suitable for subsequent oxidation reactions (usually neutral or slightly alkaline, pH 6.5–8.5). Optimizing the pH not only helps improve the oxidant's reaction efficiency but also reduces the generation of harmful gases. Second, based on the slurry's salinity test results, its salinity is adjusted to the required value (generally controlled between 1‰ and 10‰), and then remeasured to confirm compliance, ensuring that the slurry's ionic strength does not inhibit subsequent oxidation reactions.

[0030] The chemical conditioning tank 21 is also equipped with a conditioning tank sampling port 23. Samples are taken periodically through the conditioning tank sampling port 23 to detect changes in the concentration of the slurry after chemical treatment.

[0031] The mud storage unit 4 includes a mud storage tank 41 and a mud storage agitator 42. The mud storage tank 41 is connected to the chemical conditioning unit 2 and the reaction vessel 5, respectively. The mud storage agitator 42 is installed inside the mud storage tank 41. After processing, the mud is transported to a dedicated 10m³ pumping station via a high-pressure pump and a transport pipeline. 3 The mud is temporarily stored in storage tank 41. Storage tank 41 must be corrosion-resistant, leak-proof, and have stirring functions to prevent mud sedimentation.

[0032] The reaction vessel 5 includes a transparent plate 51, a temperature control system 52, a high-efficiency stirrer 53, a pH sensor, and an ORP sensor. Multiple transparent plates 51 form the chamber of the reaction vessel 5. The temperature control system 52, the high-efficiency stirrer 53, the pH sensor, and the ORP sensor are all installed in the chamber of the reaction vessel 5.

[0033] The high-efficiency mixer 53 includes a variable frequency motor and a double-layer impeller. The upper impeller of the double-layer impeller is a three-bladed oblique impeller structure, and the lower impeller of the double-layer impeller is a turbine impeller structure. The variable frequency motor is connected to and drives the double-layer impeller.

[0034] Oxidative degradation is the core process of mud treatment. Through the synergistic effect of light, stirring and temperature control, the peroxy organic acids are ensured to fully react with the pollutants in the mud, thereby achieving efficient degradation of the pollutants.

[0035] The role of light conditions: Inside reaction vessel 5, which is constructed with a transparent plate 51, sunlight can irradiate the reaction solution to stimulate the peroxy organic acids to generate highly reactive free radicals (such as hydroxyl radicals OH· and carbon-center radicals RC·). These free radicals have extremely strong oxidizing power and can rapidly decompose organic pollutants in the mud, converting them into low-toxicity or non-toxic small molecules (such as carbon dioxide, water, and oxygen).

[0036] Continuous stirring by the high-efficiency stirrer 53: To ensure sufficient contact between the peroxy organic acid and the pollutants in the reaction solution, the reactor is equipped with a high-efficiency stirrer 53, consisting of a variable frequency motor (adjustable speed, 100~600 rpm) and a three-bladed oblique impeller plus a turbine-type double-layer impeller. The upper oblique impeller of the three-bladed oblique impeller plus turbine-type double-layer impeller propels the liquid and stirs it, forming an axial flow, while the lower turbine-type impeller provides strong shearing and disperses the particles. The high-efficiency stirrer 53 continuously stirs to ensure uniform mixing of the solution, avoiding excessively high or low local concentrations, thereby improving reaction efficiency. The stirring speed needs to be adjusted according to the viscosity of the solution and the volume of the reactor to ensure effective mixing while avoiding excessive shearing that could lead to the decomposition of the peroxy organic acid.

[0037] Temperature control system 52: The reactor is equipped with a temperature control system 52 to precisely regulate the temperature of the reaction solution, maintaining the reaction temperature within the optimal range (typically 25~40℃). Excessive temperature may lead to the decomposition of peroxy organic acids or an increase in side reactions, while excessively low temperature will reduce the reaction rate. The temperature control system 52 is linked to a temperature sensor to monitor and automatically adjust the temperature in real time, ensuring the stability of the reaction conditions.

[0038] A pH sensor and an ORP sensor are installed in the reactor to monitor the pH and ORP values ​​in real time during the reaction process. Changes in pH can be used to determine whether the reaction system is too acidic or too alkaline, allowing for timely adjustment of the reagent dosage to prevent over-reaction or decreased efficacy. The ORP value reflects the oxidation capacity of the system. When the ORP is maintained within the set range (generally 650~800mV), it indicates that the system has good oxidation performance. If the ORP drops significantly and the pollutant concentration does not meet the standard, the reagent dosage should be increased or the reaction time extended in a timely manner.

[0039] Each reaction vessel 5 is equipped with a sampling port 54. Samples are taken periodically through the sampling port 54 to detect the changing trend of pollutant concentration. Periodic monitoring of pollutant concentration is used to assess the progress of the reaction. When the concentration decrease trend slows down significantly and the ORP value gradually approaches stability, it indicates that the reaction is basically completed, and it is possible to consider stopping the dosing or switching to the next treatment stage.

[0040] The dosing unit 6 includes a raw material storage tank 61, a dosing box 62, and a dosing storage tank 63. Multiple raw material storage tanks 61 are connected to the feed end of the dosing box 62. The dosing box 62 is equipped with a dosing stirrer 64. The discharge end of the dosing box 62 is connected to the dosing storage tank 63. The dosing storage tank 63 is connected to the feed port of the reaction vessel 5.

[0041] Based on the detection results of the type and concentration of chemical additives in the mud and the treatment objectives, a suitable peroxyorganic acid is selected, and its concentration range (usually 0.1%~5%) is determined. A solution of a certain concentration is prepared in the dosing tank 62. Multiple storage tanks contain different raw materials; when different peroxyorganic acids need to be prepared, the corresponding storage tank containing the raw material is opened. The dosing tank 62 is made of corrosion-resistant materials (such as stainless steel or polytetrafluoroethylene) and is equipped with a stirring device, temperature control, and safety protection facilities. The following are examples of the preparation requirements for peracetic acid and performic acid.

[0042] Peracetic acid (PAA): Suitable for degrading nitrogen- and sulfur-containing chemical auxiliaries, as well as some recalcitrant organic compounds. It is prepared using hydrogen peroxide (H₂O₂, typically 30%–50% concentration) and glacial acetic acid (CH₃COOH). Hydrogen peroxide and glacial acetic acid are mixed in a specific ratio (usually 1:1 to 1:2, by volume), and a small amount of sulfuric acid (H₂SO₄, approximately 1% by volume) is added as a catalyst. The mixture is stirred at room temperature for 2–4 hours to generate a peracetic acid solution. After the reaction is complete, the concentration of peracetic acid in the solution is measured, and diluted to the target concentration as needed.

[0043] Performic acid (PFA): It exhibits good oxidizing effects on phosphorus- and chlorine-containing chemical auxiliaries and some complexes. It is typically prepared using hydrogen peroxide (H₂O₂, concentration usually 30%–50%) and formic acid (HCOOH). Hydrogen peroxide and formic acid are mixed in a certain ratio (usually 1:1 to 1:2, volume ratio), and a small amount of sulfuric acid (H₂SO₄, approximately 1% by volume) is added as a catalyst. The mixture is stirred at room temperature for 2–4 hours to generate a performic acid solution. After the reaction is complete, the concentration of performic acid in the solution is measured, and diluted to the target concentration as needed.

[0044] The UV treatment unit 7 includes a UV lamp 71, a quartz sleeve 72, a sealed UV treatment chamber 73, a UV stirrer 74, and a UV sensor. The UV lamp 71, UV stirrer 74, and UV sensor are connected inside the UV treatment chamber 73, and the quartz sleeve 72 is connected to the outside of the UV lamp 71. The UV treatment chamber 73 is connected to the reaction vessel 5 and the mud detection unit 8.

[0045] After the oxidation reaction is completed, the mud is further disinfected by UV treatment unit 7 to completely kill pathogenic microorganisms and degrade residual organic pollutants.

[0046] The UV treatment system consists of: a UV lamp 71 emitting ultraviolet light with a wavelength of 254 nm, possessing highly efficient sterilization and degradation capabilities; a quartz sleeve 72 protecting the UV lamp 71 from direct contact with the sludge while ensuring effective UV light penetration; a UV treatment chamber 73 designed as a closed structure to prevent UV light leakage and improve treatment efficiency; and a UV agitator 74 continuously stirring to prevent sludge sedimentation.

[0047] Slurry transport and treatment: The slurry is transported from the reactor to the UV treatment unit 7 through corrosion-resistant pipes. During the transport process, the flow rate and volume of the slurry need to be controlled to ensure that the slurry flows uniformly within the reaction chamber and that it has sufficient residence time within the UV treatment chamber 73.

[0048] The mud testing unit 8 includes a testing and storage container 81 and a mud testing agitator 83. The mud testing agitator 83 is connected inside the testing and storage container 81, which is equipped with a mud outlet 82. Mud storage and sampling: The treated mud is temporarily stored in a dedicated storage tank. The storage tank must be corrosion-resistant, leak-proof, and have agitation capabilities to prevent mud sedimentation or changes in properties. Mud samples are periodically taken through the sampling port on the storage tank to ensure representativeness of the samples.

[0049] The device for treating chemical additives in reclamation mud according to this invention has the following advantages: (1) High efficiency degradation: The strong oxidizing properties of peroxy organic acids enable rapid degradation of chemical additives in land reclamation mud, especially high molecular polymer additives, with a degradation efficiency of over 90%. This improves the environmental friendliness of the mud and reduces the impact of harmful substances on the ecological environment.

[0050] (2) Environmentally friendly: Compared with the traditional chemical precipitation method, the peroxy organic acid used in this device has lower environmental toxicity, will not introduce new pollutants, and its decomposition products are harmless substances such as water and carbon dioxide, which will not cause secondary pollution and can further reduce environmental risks.

[0051] (3) Improve resource utilization: The mud treated by this device can be directly used for land reclamation, which not only reduces the discharge and landfill of waste mud, but also effectively replaces some land reclamation materials, reduces the dependence of land reclamation projects on natural resources such as sea sand, and realizes resource utilization.

[0052] (4) Strong applicability: This device can be applied to the treatment of different types of waste mud. It can effectively treat mud generated during offshore drilling, dock construction or marine engineering construction, and adapt to different soil requirements in reclamation projects.

[0053] (5) Simple operation and reduced cost: The processing technology of this device is simple and the whole process can be completed on-site at the reclamation site, which reduces the need for long-distance transportation of mud, reduces the processing and disposal costs, and improves the efficiency of the project.
