Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment system for a shipborne laboratory. Background Technology

[0002] Shipborne laboratories are specialized laboratories installed on research vessels and survey ships to conduct scientific research, environmental monitoring, resource exploration, or other specialized experiments during voyages. Currently, shipborne laboratories often use wastewater collection tanks to collect wastewater, which is then handed over to wastewater treatment facilities after the ship docks. However, the wastewater stored mixed in these collection tanks is not only difficult to treat but also poses safety risks. Therefore, it is necessary to introduce a real-time wastewater treatment system for shipborne laboratories.

[0003] However, when wastewater treatment systems are installed on land, the land environment is stable, and the requirements for vibration reduction are low. But when wastewater treatment systems are installed on ships, they have to withstand frequent vibrations, making it difficult for suspended impurities in the wastewater to settle and for the biochemical reactions in the wastewater to proceed stably. This can lead to the wastewater treatment system being unable to treat wastewater effectively, and may even result in problems such as loose pipe connections and equipment collision damage, causing wastewater leaks.

All laboratories 8 are located in the cabin above the main deck 33. Organic laboratories 81 and inorganic laboratories 82 are set up separately to avoid the cross-mixing of the two types of laboratories 8, which would cause complex and chaotic pipeline layout and make pipeline maintenance and repair difficult.

[0058] like Figure 1 and Figure 4 As shown, the wastewater treatment module 2 is located inside the ship's cabin. The wastewater treatment module 2 includes a container 21, which is equipped with multiple partitions to divide the container 21 into multiple storage compartments. Some of the storage compartments are configured as a collection homogenization tank 22, a pH adjustment tank 23, a flocculation sedimentation tank 24, an MBR membrane tank 25, and a clear water tank 26 connected in sequence. In this embodiment of the utility model, the container 21 is made of 316L stainless steel (Teflon coating) plate. The container 21 is a cube, and is divided into 11 storage compartments by partitions. The collection homogenization tank 22, pH adjustment tank 23, flocculation sedimentation tank 24, MBR membrane tank 25, and clear water tank 26 are arranged in an "S" shape from the lower left corner upwards. The storage compartments in the rightmost column are arranged from top to bottom as PAC compartment 65, PAM compartment 64, and sodium hypochlorite compartment 63. Acid compartment 61 and alkali compartment 62 are arranged side by side in the storage compartment below sodium hypochlorite compartment 63. Furthermore, the wastewater treatment module 2 also includes a sludge collection tank 27, which is located in the container in the lower right corner.

[0059] like Figure 1 , Figure 3 and Figure 4 As shown, the container 21 is equipped with an inlet 211, an outlet 212, and a sludge outlet 213. The inlet 211 is connected to the outlet of the wastewater collection module 1, the outlet 212 is connected to the inlet of the water storage tank 4, and the sludge outlet 213 is used to connect to the sludge discharge area after the ship docks, so as to discharge the sludge in the sludge collection tank 27. The flocculation sedimentation tank 24 is equipped with a sludge discharge outlet. The inlet of the collection homogenizing tank 22 is connected to the inlet 211, and the outlet of the clear water tank 26 is connected to the outlet 212. The sludge discharge outlet of the flocculation sedimentation tank 24 is connected to the inlet of the sludge collection tank 27, the drainage outlet of the sludge collection tank 27 is connected to the inlet of the collection homogenizing tank 22, and the sludge outlet of the sludge collection tank 27 is connected to the sludge outlet 213. In this embodiment of the utility model, the inlet 211 is located at the top of the collection homogenizing tank 22, and the inlet 211 is the water inlet of the collection homogenizing tank 22. The outlet 212 is located at the top of the clear water tank 26, and the outlet 212 is the water outlet of the clear water tank 26. The sludge outlet 213 is located on the right side of the sludge collection tank 27, and the sludge outlet 213 is the sludge outlet of the sludge collection tank 27.

[0060] Furthermore, such as Figure 1 As shown in this embodiment of the utility model, the wastewater treatment module 2 is located in the cabin below the main deck 33. The wastewater collection module 1 includes a first pipe network 11 and a second pipe network 12. The drain outlets of each organic laboratory 81 are connected to the inlet 211 through the first pipe network 11, and the drain outlets of each inorganic laboratory 82 are connected to the inlet 211 through the second pipe network 12. The first pipe network 11 and the second pipe network 12 converge into a main inlet pipe near the inlet 211. The main inlet pipe is connected to the inlet 211. By collecting wastewater generated by different types of laboratories through two sets of pipe networks, it is possible to avoid the premature mixing of wastewater from different types of laboratories and the occurrence of violent reactions in the pipes, which could damage the pipes and lead to safety accidents.

[0061] Furthermore, in order to meet the normal operation requirements of the pipeline, in this embodiment of the utility model, all pipelines above the main deck 33 are made of PP material to meet the requirements for acid and alkali corrosion resistance; all pipelines below the main deck 33 are made of stainless steel lined with Teflon coating to meet the fire protection requirements of the mechanical space; and steel-plastic joints are used to connect the joints of the two types of pipelines.

[0062] Furthermore, such as Figures 3 to 5As shown, in order to ensure that the wastewater treatment module 2 is not affected by the swaying of the ship, a vibration isolation module 3 is provided on the wastewater treatment module 2. The vibration isolation module 3 includes a first vibration isolation component 31 and a second vibration isolation component 32. The first vibration isolation component 31 is located between the bottom surface of the container 21 and the cabin, and the second vibration isolation component 32 is located between the side of the container 21 and the cabin.

[0064] Furthermore, such as Figure 6 As shown, the bottom of the high-damping rubber vibration isolator 3111 is fixedly installed on the mounting base 35 by bolts, and its top abuts against the bottom surface of the mounting plate 34. The mounting plate 34 is provided with mounting holes. Bolts are screwed into the mounting holes of the mounting plate 34 and the mounting holes of the high-damping rubber vibration isolator 3111 in sequence from the top of the mounting plate 34 downwards, thereby fixing the high-damping rubber vibration isolator 3111. By setting the high-damping rubber vibration isolator at the bottom of the housing 21, energy can be absorbed when the ship is vertically rocking, thereby reducing the impact of vertical vibration on the wastewater treatment module 2.

When the second connector 28 is installed, the connecting plate 284 rests against the side of the receiving box 21 and is fixed to the side of the receiving box 21 by bolts. When the wire rope vibration isolator 3211 is installed, the second screw is simultaneously screwed into the mounting hole and the second mounting hole 281 of the wire rope vibration isolator 3211, thereby fixing the wire rope vibration isolator 3211 to the side of the receiving box 21.

[0069] like Figure 3 As shown, to reduce the impact of ship swaying on the external pipe joints of the wastewater treatment module 2, flexible joints 7 are provided at both the inlet 211 and the outlet 212 for connecting the wastewater collection module 1 or the water storage tank 4. In this embodiment, the flexible joint 7 is a fluororubber ball joint. The fluororubber ball joint is installed on the inlet 211 and connected to the pipe of the wastewater collection module 1. The fluororubber ball joint is also installed on the outlet 212 and connected to the inlet of the water storage tank 4 via a pipeline. Furthermore, the various tanks / pools within the wastewater treatment module 2 are connected by connecting pipes. To reduce the impact of ship swaying on the pipe joints inside the wastewater treatment module 2, flexible joints 7 are provided at the ends of the connecting pipes. In this embodiment, the flexible joints 7 at the ends of the connecting pipes are stainless steel corrugated flexible hose joints.

[0070] Furthermore, such as Figure 1As shown, the inlet of the water storage tank 4 is connected to the outlet 212, and the outlet of the water storage tank 4 is used to connect to the municipal drainage network. In this embodiment of the invention, an entire compartment is used as the water storage tank 4. Compared with the collection bucket in the prior art, the wastewater collection capacity of this embodiment of the invention is greatly increased, and the ship does not need to return to port to discharge wastewater in a short time, allowing the ship to travel a longer distance at sea. Furthermore, in order to facilitate the discharge of wastewater to the municipal network after returning to port, the wastewater treatment system of this embodiment of the invention also includes a shore pump 36. The inlet of the shore pump 36 is connected to the outlet of the water storage tank 4, and the outlet of the shore pump 36 is used to connect to the municipal drainage network. After the ship docks, the outlet of the shore pump 36 is connected to the municipal drainage network, and the wastewater is pumped to the drainage network by the shore pump 36 to complete the discharge of wastewater.

[0071] Furthermore, such as Figure 14 As shown, the wastewater treatment system of the shipborne laboratory also includes a controller 9. In this embodiment of the invention, the controller 9 includes a PLC control box 91 and a signal acquisition box 92, which are directly connected by electrical signals.

[0072] Furthermore, a first lift pump 221 and a first liquid level sensor 222 are installed on the collection homogenization tank 22. The first lift pump 221 is electrically connected to the PLC control box 91, and the first liquid level sensor 222 is electrically connected to the signal acquisition box 92.

[0073] When the system is working, wastewater from each laboratory 8 continuously enters the collection homogenization tank 22, and the liquid level in the collection homogenization tank 22 continuously rises. After reaching the limit liquid level, the first liquid level sensor 222 activates an electrical signal to the signal acquisition box 92. The signal acquisition box 92 transmits the signal to the PLC control box 91, and the PLC control box 91 controls the first booster pump 221 to start and transport the wastewater into the pH adjustment chamber 23.

[0074] Furthermore, the pH adjustment chamber 23 is equipped with a first dosing metering pump 231 and a pH sensor 232. The first dosing metering pump 231 is electrically connected to the PLC control box 91, and the pH sensor 232 is electrically connected to the signal acquisition box 92. In this embodiment of the invention, there are two first dosing metering pumps 231. The inlets of the two first dosing metering pumps 231 are respectively connected to the acid chamber 61 and the alkali chamber 62, and the outlets of the two first dosing metering pumps 231 are connected to the pH adjustment chamber 23.

[0075] After the wastewater enters the pH adjustment chamber 23, the pH sensor 232 detects the pH value of the wastewater and transmits the signal to the signal acquisition box 92. The signal acquisition box 92 processes and analyzes the signal. When the pH value of the wastewater exceeds the predetermined range (6.0-8.5), the signal acquisition box 92 sends a signal to the PLC control box 91. The PLC control box 91 controls the start of the first dosing metering pump 231 to neutralize the wastewater in the pH adjustment chamber 23 by adding chemicals.

[0076] Furthermore, the flocculation sedimentation tank 24 is equipped with a first aeration blower 241 and an aeration and stirring device. The air inlet of the aeration and stirring device is connected to the air outlet of the first aeration blower 241. The flocculation sedimentation tank 24 is also equipped with two second dosing pumps 242. Each second dosing pump 242 and the first aeration blower 241 are electrically connected to the PLC control box 91. In this embodiment of the invention, the inlets of the two second dosing pumps 242 are connected to the PAC chamber 65 and the PAM chamber 64, respectively, and the outlets of the two second dosing pumps 242 are connected to the flocculation sedimentation tank 24.

[0077] After receiving the signal to start the first booster pump 221, the PLC control box 91 starts the first aeration blower 241 after a certain delay, and then starts the aeration and stirring device. After stirring for a period of time, the PLC control box 91 controls the two second dosing metering pumps to add chemicals and carry out flocculation and sedimentation treatment. When the supernatant liquid level in the flocculation and sedimentation tank 24 reaches the set level, it flows directly into the MBR membrane tank 25.

[0078] Furthermore, the MBR membrane tank 25 is equipped with a first float switch 251, a second float switch 252, a second aeration fan 253, a fourth dosing pump 255, a third lift pump 256, and a backwash pump 254. The first float switch 251 and the second float switch 252 are electrically connected to the signal acquisition box 92, and the second aeration fan 253, the fourth dosing pump 255, the third lift pump 256, and the backwash pump 254 are all electrically connected to the PLC control box 91. In this embodiment, the inlet of the fourth dosing pump 255 is connected to the sodium hypochlorite chamber 63, and the outlet of the fourth dosing pump 255 is connected to the MBR membrane tank 25.

[0079] When the supernatant in the flocculation sedimentation tank 24 flows into the MBR membrane tank 25 and reaches the set low level, the first float switch is activated and sends a signal to the signal acquisition box 92. The signal acquisition box 92 then sends a signal to the PLC control box 91, which starts the second aeration fan 253 and the backwash pump 254. After the second aeration fan 253 and the backwash pump 254 have been running for a certain period of time, the PLC control box 91 starts the fourth dosing metering pump 255 to add chemicals. When the liquid level in the MBR membrane tank 25 reaches the set high level, the second float switch 252 is activated and sends a signal to the signal acquisition box 92. The signal acquisition box 92 then sends a signal to the PLC control box 91, which starts the third lift pump 256 and pumps the treated water into the clear water tank 26 until the first float switch 251 is closed.

[0080] Furthermore, the clear water tank 26 is equipped with a third float switch 261, a second lift pump 262, a residual chlorine sensor 264, and a third dosing pump 263. The third float switch 261 and the residual chlorine sensor 264 are electrically connected to the signal acquisition box 92, and the second lift pump 262 and the third dosing pump 263 are electrically connected to the PLC control box 91. In this embodiment of the invention, the inlet of the third dosing pump 263 is connected to the sodium hypochlorite chamber 63, and the outlet of the third dosing pump 263 is connected to the clear water tank 26.

[0081] When the third booster pump 256 starts, treated water continuously flows into the clear water tank 26. The residual chlorine sensor 264 detects the sodium hypochlorite concentration in the water and transmits the detection signal to the signal acquisition box 92. The signal acquisition box processes the signal and sends a command to the PLC control box 91. The PLC control box 91 then controls the start of the third dosing metering pump 263 to add chemicals. When the water level in the clear water tank 26 reaches the set high level, the third float switch 261 starts and sends a signal to the signal acquisition box 92. The signal acquisition box 92 sends a signal to the PLC control box 91, which then starts the second booster pump 262 and pumps the treated water into the water storage tank 4.

[0082] Furthermore, a second liquid level sensor 41 is installed in the water storage tank 4. The second liquid level sensor 41 is connected to the signal acquisition box 92. When the water level in the water storage tank 4 reaches the set high liquid level, the second liquid level sensor 41 sends a signal to the signal acquisition box 92, and the signal acquisition box 92 sends a signal to the PLC control box. The PLC control box controls the wastewater treatment module 2 to stop working.

[0083] Furthermore, the water storage tank 4 is also equipped with a backup pump for the bank drainage pump 36. A pressure sensor 37 is installed at the outlet of the bank drainage pump 36. The pressure sensor 37 is electrically connected to the signal acquisition box 92, and the bank drainage pump 36 is electrically connected to the PLC control box 91. The pressure sensor 37 detects the water pressure at the outlet of the bank drainage pump 36 and transmits the pressure signal to the signal acquisition box 92. The signal acquisition box 92 analyzes and compares the signal. When the pressure is lower than the specified value, the signal acquisition box 92 sends a signal to the PLC control box 91. The PLC control box starts the backup pump and shuts down the bank drainage pump 36.

[0084] Furthermore, the controller 9 also includes a human-machine interface 93, which is electrically connected to the PLC control box 91. Operators can set and adjust key parameters on the human-machine interface 93 and receive relevant alarm information on the human-machine interface 93, thereby realizing remote monitoring and flexible control of the wastewater treatment system.

[0085] In summary, the wastewater treatment system for a shipborne laboratory provided by this utility model embodiment collects wastewater generated by each laboratory 8 through a wastewater collection module 1. The collected wastewater flows into a wastewater treatment module 2, where it undergoes homogenization, neutralization, flocculation sedimentation, filtration, and disinfection to ensure that the wastewater meets municipal drainage standards. The treated water is then stored in a water storage tank 4 and discharged into the municipal drainage network after docking. This utility model embodiment provides real-time treatment of laboratory wastewater, avoiding the problems of violent reactions or increased treatment difficulty caused by mixed storage of laboratory wastewater, and also preventing accidental leakage of laboratory wastewater stored in collection tanks.

[0086] By using a controller to manage the entire water treatment process on board, real-time monitoring and automated control of the water treatment system are achieved, enabling automatic wastewater treatment, reducing manual intervention, and significantly improving wastewater treatment efficiency.

[0087] To ensure that the wastewater treatment module 2 is protected from the effects of ship swaying, this embodiment of the invention divides the container 21 into different compartments using partitions. Each compartment serves as a pool within the wastewater treatment module 2, enhancing the connection strength between the compartments and improving the overall rigidity of the module, thus reducing the impact of ship swaying on the module. Simultaneously, a first vibration isolation component 31 is installed between the bottom of the container 21 and the deck inside the ship's hold to limit vertical vibration, and a second vibration isolation component 32 is installed between the side of the container 21 and the side plate of the ship's hold to limit horizontal vibration. The installation of the vibration isolation modules 3 further reduces the impact of ship swaying on the wastewater treatment module 2, solving the technical problem in the prior art where wastewater treatment systems installed on ships are subjected to frequent vibrations, leading to ineffective wastewater treatment and even loose pipe connections and equipment damage from collisions.

[0088] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
