Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an integrated vessel for electrochemical synergistic ultrasonic algae removal and water quality restoration. Background Technology

[0002] The phenomenon of algae rapidly multiplying in water bodies under specific conditions, forming a large number of phytoplankton, is called algal bloom. Currently, the main methods for dealing with algal blooms include physical treatment, chemical treatment, biological treatment, and ecological restoration. Physical treatment includes mechanical removal of algae and the use of ultrasound to remove algae. Chemical treatment uses agents and disinfectants to inhibit algal growth. Biological treatment uses aquatic organisms and microorganisms to control the number of algae. Ecological restoration improves water quality through wetland construction and vegetation restoration.

[0003] In the prior art, such as the patent with publication number CN222390402U, a vessel for simultaneous water purification and algae removal is disclosed. The vessel includes a hull, on which are fixed algae removal reaction chambers, SS removal reaction chambers, and nitrogen and phosphorus removal chambers. The inlet ends of the three chambers are respectively connected to liquid pump one, liquid pump two, and liquid pump three. An algae removal agent storage chamber is fixed at the upper end or side wall of the algae removal reaction chamber, which stores the algae removal agent potassium ferrate. An algae removal agent dosing port is provided between the algae removal agent storage chamber and the algae removal reaction chamber. An inlet is opened at the upper part of the algae removal reaction chamber, and an outlet is opened at the lower part. An iron ion one-way pressure osmosis membrane is provided at the outlet to retain iron ions in the chamber.

[0004] The above structure treats the water through three compartments: algae removal, suspended solids (SS) removal, and nitrogen and phosphorus removal. However, during the water treatment process, it is impossible to coordinate ultrasound and electrochemistry for algae removal, resulting in poor separation of water from algae and flocs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an integrated vessel for electrochemical and ultrasonic algae removal and water quality restoration, so as to solve the problem that in the process of water treatment, it is impossible to combine ultrasonic and electrochemical algae removal, resulting in poor separation of water from algae sediment and flocs.

[0006] Based on the above objectives, this utility model provides an integrated vessel for electrochemical synergistic ultrasonic algae removal and water quality restoration, including a catamaran and a propeller at the end of the catamaran. The propeller is used to drive the catamaran to move. A hull bridge is fixedly installed inside the catamaran. An electric tailgate is provided at the end of the hull bridge. A drainage channel is opened inside the hull bridge. Multiple sets of electrocoagulation zones and multiple sets of electroFenton zones are fixedly installed inside the drainage channel. The multiple sets of electrocoagulation zones and multiple sets of electroFenton zones are staggered.

[0007] Ultrasonic sensors are arrayed on both sides of the bridge, and multiple sets of ultrasonic sensors are installed on one side of the catamaran.

[0008] Multiple concentration sensors are fixedly installed on the bottom of the catamaran. The concentration sensors are located inside the bridge and are electrically connected to the ultrasonic sensors. A hydrocyclone device is also installed inside the flow channel. The hydrocyclone device is located near the electric tailgate, and a sediment capture net is fixedly connected to the bottom of the hydrocyclone device.

[0009] Preferably, at least four sets of electrocoagulation zones and electroFenton zones are provided, and the spacing between two adjacent sets of electrocoagulation zones is mm-mm.

[0010] Preferably, at least four sets of ultrasonic sensors are provided, and the ultrasonic sensors are distributed between two adjacent sets of electrocoagulation zones and two adjacent sets of electroFenton zones.

[0011] Preferably, the hydrocyclone device includes at least four rotary motors and four blades, with the output ends of the rotary motors connected to the blades, which extend beyond the catamaran.

[0012] Preferably, the electrocoagulation zone is an iron electrode plate generated by electrocoagulation, and the electro-Fenton zone is a titanium-based coated electrode plate generated by electro-Fenton. The titanium-based coated electrode plate is externally loaded with an IrO-TaO catalyst layer, and multiple sets of pores are formed inside both the electrocoagulation zone and the electro-Fenton zone.

[0013] Preferably, the concentration sensors are evenly distributed at the bottom of the catamaran, and the concentration sensors are used to monitor the concentration of algae.

[0014] The beneficial effects of this utility model are:

[0015] When the catamaran is sailing on the water, the algae-laden water enters the flow path formed by the electrocoagulation zone and the electro-Fenton zone set on both sides of the bottom of the ship through the diversion channel. Along the direction of water flow, it first passes through the electrocoagulation zone to remove nitrogen and phosphorus from the water, and captures algae to form large flocs that settle. Then it passes through the electro-Fenton zone to continue to remove algae through oxidation, while removing algal toxins and organic phosphorus released by the dead algae. At the same time, ultrasonic sensors coupled to both sides of the hull are used for synergistic algae removal. The treated algae and flocs settle under the centrifugal force of the hydrocyclone device at the stern, and then the sedimentation and capture net is used to achieve efficient separation of water from algae sediment and flocs.

[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 specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, an integrated vessel for electrochemical synergistic ultrasonic algae removal and water quality restoration includes a catamaran 1 and a propeller 10 at the end of the catamaran 1. The propeller 10 is used to drive the catamaran 1 to move. A hull bridge is fixedly installed inside the catamaran 1. An electric tailgate 9 is provided at the end of the hull bridge. A drainage channel 2 is opened inside the hull bridge. Multiple sets of electrocoagulation zones 3 and multiple sets of electroFenton zones 4 are fixedly installed inside the drainage channel 2. The multiple sets of electrocoagulation zones 3 and multiple sets of electroFenton zones 4 are staggered.

[0023] Ultrasonic sensors 5 are arrayed on both sides of the bridge, and multiple sets of ultrasonic sensors 5 are installed on one side of the catamaran 1.

[0024] Multiple concentration sensors 6 are fixedly installed at the bottom of the catamaran 1. The concentration sensors 6 are located inside the bridge and are electrically connected to the ultrasonic sensor 5. A hydrocyclone device 7 is also installed inside the diversion channel 2. The hydrocyclone device 7 is located near the electric tailgate 9. A sedimentation capture net 8 is fixedly connected to the bottom of the hydrocyclone device 7.

[0025] In this embodiment, when the catamaran 1 is sailing on the water surface, the algae-infused water enters the flow path formed by the electrocoagulation zone 3 and the electro-Fenton zone 4 set on both sides of the bottom of the ship through the diversion channel 2. Along the direction of water flow, it first passes through the electrocoagulation zone 3 to remove nitrogen and phosphorus from the water, and the algae are captured to form large flocs that settle. Then, it passes through the electro-Fenton zone 4 to continue to remove algae through oxidation, while removing algal toxins and organic phosphorus released by the dead algae. At the same time, the ultrasonic sensors 5 coupled to both sides of the ship are used to remove algae in a coordinated manner. The treated algae and flocs are precipitated under the centrifugal force of the hydrocyclone device 7 at the stern, and then the sedimentation capture net 8 is used to achieve efficient separation of the water from the algae sediment and flocs.

[0026] As one implementation method, such as Figure 1 , Figure 2 As shown, at least four sets of electrocoagulation zones 3 and electroFenton zones 4 are provided, and the distance between two adjacent sets of electrocoagulation zones 3 is 50mm-100mm.

[0027] In this embodiment, the water body is treated sequentially through multiple sets of electrocoagulation zones 3 and electro-Fenton zones 4. First, the nitrogen and phosphorus in the water body are removed by electrocoagulation technology, while algae are captured to form large flocs to improve the algae removal efficiency of the ultrasonic device. Then, the algae and organic phosphorus and algal toxins in the water are further oxidized by electro-Fenton technology.

[0028] As one implementation method, such as Figure 1 , Figure 2 As shown, at least four sets of ultrasonic sensors 5 are provided, and the ultrasonic sensors 5 are distributed between two adjacent sets of electrocoagulation zones 3 and two adjacent sets of electroFenton zones 4.

[0029] In this embodiment, the transmitter and receiver in the ultrasonic sensor 5 are respectively installed on one side of the catamaran 1. The high-frequency ultrasonic waves are used to excite the "cavitation effect" in the liquid, which replaces aeration to delay the passivation of the electrode plates inside the electrocoagulation zone 3 and the electro-Fenton zone 4.

[0030] As one implementation method, such as Figure 1 , Figure 2 As shown, the hydrocyclone device 7 includes at least four rotary motors and four blades, with the output end of the rotary motors connected to the blades, which extend to the outside of the catamaran 1.

[0031] In this embodiment, a rotary motor drives the paddle to rotate in the water, thereby generating centrifugal force, which allows dead algae and flocs to settle under the action of centrifugal force.

[0032] As one implementation method, such as Figure 2 , Figure 3 As shown, the electrocoagulation zone 3 is an iron electrode plate generated by electrocoagulation, and the electro-Fenton zone 4 is a titanium-based coated electrode plate generated by electro-Fenton. The titanium-based coated electrode plate is loaded with an IrO2-Ta2O5 catalyst layer. Multiple sets of pores are opened inside the electrocoagulation zone 3 and the electro-Fenton zone 4.

[0033] In this embodiment, multiple sets of iron electrode plates and titanium-based coated electrode plates are used to form a flow path. As the water flows through the flow path, the perforated plate enhances the flowability of the water, which greatly improves the treatment efficiency.

[0034] As one implementation method, such as Figure 1 , Figure 2 As shown, concentration sensors 6 are evenly distributed at the bottom of the catamaran 1. Concentration sensors 6 are used to monitor the concentration of algae.

[0035] In this embodiment, the concentration sensor 6 is evenly distributed at the bottom of the catamaran 1. It is used to sense changes in algae concentration to avoid excessive energy consumption. When the concentration sensor 6 in the middle of the catamaran 1 detects the algae density decrease rate, the ultrasonic power in the ultrasonic sensor 5 is increased to the upper limit.

[0036] This specification also provides an embodiment of a water body restoration method for algae removal vessels, including the following steps:

[0037] S1. Drain algae-containing water into the channel with an initial flow velocity of 0.3 m / s;

[0038] S2, Electrocoagulation Stage: A 10-15 V DC current is applied to the iron electrode, generating Fe(OH)3 colloid that adsorbs PO4. 3- Combined netting to capture algae;

[0039] S3, Electro-Fenton-Ultrasonic Synergistic Stage: Titanium electrode electrolyzes water to produce H2O2, which reacts with Fe... 2+ The reaction generates ·OH, which is simultaneously broken down by ultrasonic cavitation, enhancing the diffusion of ·OH.

[0040] S4. Cyclone Separation and Capture: Adjust the opening of the electric tailgate 9 to 70% to allow the flocs to settle under a centrifugal force of >800 g; use a 200-mesh sedimentation and capture net 8 to separate and capture the flocs and algae sediments;

[0041] S5, Intelligent Feedback: When the algae concentration sensor 6 detects an algae density decrease rate of <10% / min, the ultrasonic power is increased to the upper limit.

[0042] In step S2, the Fe² release was controlled at 5-10 mg / L, and the ORP was maintained at 200-300 mV.

[0043] In step S3, the in-situ H2O2 generation rate is ≥0.5 mmol / (h·cm²), and the ·OH concentration is >10. -4 mol / L.
