The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0049] The ballast water sediment treatment system for wharves provided in this embodiment has two layout modes:

[0050] (1) Split-type mode

[0051] The ballast water sediment treatment system at the wharf is housed in a separate container, forming a modular system.

[0054] This embodiment uses a split-model where the equipment module is placed separately in a container as an example.

[0055] Figures 1-3 The images shown are a front view, a top view, and a schematic diagram of the ballast water sediment treatment system provided in this embodiment of the application. The ballast water sediment treatment system mainly includes the following components:

[0056] Chemical storage tank 1 is used to store chemicals for treating ballast water sediments;

[0057] The dosing and dispensing system 3 is connected to the drug storage tank 1 and is used to quantitatively draw the drug from the drug storage tank 1, prepare it into a drug solution, and output it in a quantitative manner.

[0058] The sludge dewatering system 4 is connected to the chemical dosing system 3 and the wharf ballast water treatment system. It is used to add the chemical solution input from the chemical dosing system 3 to the sludge-containing sewage liquid input from the wharf ballast water treatment system, and to remove the water from the sewage liquid by pressing, and the resulting sludge cake is discharged.

[0059] Specifically, the chemical storage tank 1 is a storage container for chemicals used in the treatment of ballast water sediments, and can be configured according to actual needs.

[0060] The agent used for treating ballast water sediments is a dry powder.

[0061] Furthermore, the interior of the chemical storage tank 1 is divided into multiple independent compartments (such as oxidant compartment, flocculant compartment, and pH adjuster compartment), each with a capacity of 50-200 kg, and is isolated by airtight partitions to avoid cross-contamination of chemicals.

[0062] The pharmaceutical storage tank 1 is equipped with a built-in temperature and humidity sensor (accuracy ±0.5℃, ±3%RH) and an automatic drying device (dew point ≤ -40℃) to ensure the stability of the pharmaceutical powder.

[0063] In a preferred embodiment, a high-frequency vibrator (frequency 50-100Hz) is installed at the bottom of the medicine storage tank 1 and is activated at regular intervals (exemplarily: every hour, 10 seconds each time) to prevent the medicine powder from clumping.

[0064] The dosing and dispensing system 3 can automatically dissolve and add chemicals, achieving precise dosing and enhancing sterilization and sludge flocculation effects.

[0065] Specifically, the drug dispensing and administration system 3 includes:

[0066] A quantitative dispensing device is connected to the medicine storage tank 1 and is used to quantitatively dispense the medicine in the medicine storage tank 1.

[0067] A dynamic mixer is used to mix and dissolve various agents to prepare a solution for treating ballast water sediments.

[0068] The chemical dosing unit is used to quantitatively add the chemical solution from the dynamic mixer to the sludge dewatering system.

[0069] In a preferred embodiment, the quantitative absorption device employs a screw feeder. The input end of the screw feeder is connected to the outlet of the compartment of the drug storage tank 1, and the output end of the screw feeder is connected to the inlet of the dynamic mixer, so as to transport the drug in the drug storage tank 1 to the dynamic mixer.

[0070] Furthermore, the screw feeder uses a stainless steel screw driven by a servo motor, with adjustable speed (5-50 rpm) and drug delivery accuracy of ±1.5%.

[0071] Furthermore, a corresponding number of screw feeders are set according to the number of compartments in the pharmaceutical storage tank.

[0072] Furthermore, high-precision weighing sensors (range 0–50 kg, error ±0.1%) are installed at the input end of the screw feeder (i.e., the outlet of the pharmaceutical storage tank) and / or the output end of the screw feeder (i.e., the inlet of the dynamic mixer) to monitor the amount of pharmaceutical powder added in real time. The weighing sensors are connected to the controller to achieve intelligent control.

[0073] A water tank is located on one side of the dynamic mixer to supply water for dissolving the dry powder.

[0074] Preferably, the water tank is equipped with a heater to heat the water, ensuring that the water temperature matches the corresponding drug solubility curve.

[0075] Preferably, a flow meter is installed at the outlet of the water tank to precisely control the amount of water entering the dynamic mixer. The flow meter is connected to the controller.

[0076] In a preferred embodiment, the dynamic mixer is equipped with an ultrasonic atomizing device that uses a 20kHz ultrasonic transducer to atomize water molecules into 5-10μm droplets, allowing them to fully contact the powder and improving the dissolution efficiency by 60% compared to traditional stirring.

[0077] In a preferred embodiment, the dynamic mixer is equipped with multi-stage mixing chambers, such as a three-stage mixing chamber (with diameters decreasing progressively: 200mm → 100mm → 50mm), which accelerates mixing through the Venturi effect and shortens the drug preparation time to less than 3 minutes.

[0078] In a preferred embodiment, the dynamic mixer is equipped with a drug concentration sensor to detect the concentration of the prepared drug solution in real time, thereby maintaining the drug concentration within a set range. The drug concentration sensor is connected to a controller.

[0079] The system adopts a precise closed-loop dosing mechanism, based on a triple feedback mechanism of drug weighing, water flow and concentration data, to achieve closed-loop control of the entire process of "powder-water-dosing". The drug utilization rate is ≥98%, and the prepared drug solution is accurate, highly uniform and efficient.

[0080] The chemical dosing unit includes an electric pump, a chemical delivery pipeline, and a multi-point injection system connected in sequence. The electric pump draws the chemical solution from the dynamic mixer and delivers it to the multi-point injection system through the chemical delivery pipeline. The multi-point injection system is located in the sludge dewatering system 4.

[0081] In a preferred embodiment, the electric pump has a flow rate range of 0.1–100 L / h, is made of corrosion-resistant material (PTFE diaphragm + 316L pump body), supports pulse suppression function, and has a flow fluctuation of ≤±2%. The electric pump adopts frequency conversion control, automatically adjusting the pump speed according to the flow signal to achieve on-demand dosing.

[0082] In a preferred embodiment, the multi-point spraying system uses annular nozzles (0.5 mm in diameter, 8 to 12 in number) to ensure uniform diffusion of the liquid and even spraying it onto the ballast water sludge to be treated.

[0083] The sludge dewatering system 4 uses a twin-screw press with an adjustable pressure of 0.5–2.5 MPa. First, the chemical solution input from the dosing system 3 is added to the sludge-containing wastewater input from the dock ballast water treatment system, forming flocs. After being pressed by the twin screw press, the water in the wastewater is removed, and the remaining sludge cake with low water content is discharged outside the tank. The treated water is then discharged into the sea, completing the system's wastewater treatment process.

[0084] In a preferred embodiment, the sludge dewatering system 4 further includes a microwave drying device with a frequency of 2.45 GHz. The sludge cake after double-screw pressing is further dewatered by the microwave drying device, which can reduce the sludge moisture content to below 15%.

[0085] In a preferred embodiment, the wharf ballast water sediment treatment system further includes a concentration system 5, located between the wharf ballast water treatment system and the sludge dewatering system 4, for concentrating the sludge-containing wastewater discharged from the wharf ballast water treatment system and then transporting it to the sludge dewatering system 4.

[0086] In a preferred embodiment, the concentration system 5 employs a disc filter. For example, a three-stage disc filter (pore size 50μm→20μm→5μm) is used to perform three-stage filtration of wastewater, and the concentrated liquid is transported to the sludge dewatering system 4 via a screw pump.

[0087] Furthermore, the disc filter is equipped with an automatic backwashing module, which triggers cleaning via a pressure sensor to prevent filter clogging.

[0088] In a preferred embodiment, the wharf ballast water sediment treatment system further includes a system integration box 2, which serves as the outer shell of the equipment modules. The reagent storage tank 1, the dosing and dispensing system 3, the sludge dewatering system 4, and the concentration system 5 are all located inside the system integration box 2.

[0089] As needed, the system integration box 2 also contains sanitary ware 6 and other ventilation, lighting, piping and electrical circuit installation accessories.

[0090] In operation, vessels requiring onshore ballast water treatment, after docking at the pier, connect the ballast water in their ballast tanks to the inlet of the pier's ballast water treatment system via a quick-connect pipe. The pier's ballast water treatment system is then activated to sterilize the ballast water. The sludge-containing effluent discharged from the pier's ballast water treatment system is simultaneously treated by the pier ballast water sediment treatment system provided in this embodiment, achieving sludge reduction and efficient treatment.

[0091] The specific working method of the wharf ballast water sediment treatment system provided in this embodiment is as follows:

[0092] The dosing and dispensing system 3 quantitatively absorbs the reagent from the reagent storage tank 1, prepares it into a liquid, and quantitatively delivers it to the sludge dewatering system 4;

[0093] The sludge-containing wastewater discharged from the ballast water treatment system at the dock first enters the thickening system 5, which further concentrates the wastewater before sending it to the sludge dewatering system 4.

[0094] In sludge dewatering system 4, the chemical solution is added to the concentrated sludge to form flocs. After being pressed by a double screw and dried by microwave, the water in the sludge is removed, and the remaining sludge cake is discharged out of the tank. The treated water is discharged into the sea, completing the sludge treatment of the system.

[0095] The following specific embodiment illustrates the effectiveness of the ballast water sediment treatment system for wharves provided in this application.

[0096] A certain dock handles 300m³ of ballast water 3 Sodium hypochlorite and polyacrylamide need to be added per hour.

[0097] The reagent storage tank 1 is equipped with an oxidant compartment and a flocculant compartment, with capacities of 500 kg and 200 kg respectively. The oxidant compartment contains sodium chlorate, and the flocculant compartment contains polyacrylamide.

[0098] The dosing system 3 draws sodium hypochlorite powder from the oxidant chamber and polyacrylamide from the flocculant chamber, with the weighing sensor calibrated in real time. Constant temperature water (25℃) is injected into the dynamic mixer, and ultrasonic atomization is activated. The powder and water are gradually pressurized and mixed in a three-stage mixing chamber, forming a uniform solution within 3 minutes. The solution is then added to the sludge dewatering system 4 via a metering pump at a rate of 60L / h. A ring nozzle (12 holes, 0.5mm diameter) ensures uniform diffusion of the solution. An online residual chlorine sensor monitors the concentration in real time, and the pump speed is adjusted in a closed-loop manner to maintain residual chlorine at 1.5±0.1ppm.

[0099] The specific parameter configurations are as follows:

[0100] Processing capacity <![CDATA[300m 3 / h]]> <![CDATA[Ballast water flow rate range 100~500m 3 / h]]> Sodium hypochlorite dosage concentration 1.5ppm The corresponding powder dosage is 4.5 kg / h. Polyacrylamide dosage concentration 0.2％ The corresponding powder dosage is 0.6 kg / h. Dispensing speed ≤3 minutes / batch Single batch dosage: 300L

[0101] The sludge-containing wastewater discharged from the ballast water treatment system at the wharf first enters the thickening system 5, where a three-stage disc filter removes suspended solids in stages, and the concentrated liquid is then pumped to the sludge dewatering system 4 by a screw pump.

[0102] The chemical solution is added to the concentrate to form dense flocs, increasing the settling velocity by 40%. A twin-screw press squeezes the sludge at a pressure of 1.8 MPa, removing 70% of the free water to form a semi-dry sludge cake with a moisture content of 40%. The sludge cake then enters a microwave drying module (2.45 GHz, 15 kW) to further reduce the moisture content to ≤15%. The dried sludge cake (≤20 kg per bag) is labeled with barcodes before being transported, supporting traceability management. The treated water is tested by an online water quality analyzer, and the TOC (≤50 mg / L), turbidity (≤5 NTU), and residual chlorine (≤0.1 ppm) levels meet the standards for discharge into the sea.

[0103] The technical effects of the wharf ballast water sediment treatment system provided in this application compared with traditional processes are as follows:

[0104]

[0105] The ballast water sediment treatment system provided in this embodiment can conveniently solve the treatment of sewage discharged from the ballast water treatment system. After the sewage is concentrated and dehydrated, the discharged mud cake has a low water content, which greatly reduces the weight and volume of the sewage and makes it easy to collect.

[0106] The ballast water sediment treatment system provided in this embodiment is suitable for shore-based emergency treatment of ship ballast water, realizing sludge reduction, synchronous treatment and efficient discharge, and also makes it more possible to install ballast water treatment equipment on the dock.

[0107] This invention, through modular design, integrated concentration and dehydration process, and automated control, significantly reduces the construction and operation costs of wharves, improves ballast water treatment efficiency, provides a reliable solution for emergency ship discharge, and has broad market application prospects.
