Description

Technical Field

[0001] The utility model relates to the technical field of blue algae treatment, in particular to a blue algae separation ship. Background Art

[0002] The massive growth of algae in water bodies can reduce the transparency of the water body, affect the normal flow of water, and easily cause the microorganisms in the river to grow too fast, causing the water quality to deteriorate. Therefore, it needs to be cleaned frequently. The water blooms in my country's inland lakes are mainly cyanobacteria. The more common method of collecting cyanobacteria is to collect them with a cleaning boat and then transport them to the ground for treatment. There are manual salvage operations, which are less efficient; there are also water pumps for suction operations, but when collecting cyanobacteria, a large amount of water will be sucked up together. The amount of cyanobacteria processed each time the boat goes out is limited, and the efficiency is low. Therefore, how to improve the collection efficiency of cyanobacteria is a problem that technicians in this field need to consider. Utility Model Content

[0020] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0021] like Figure 1-Figure 2 As shown, the utility model is applied to the collection and treatment of cyanobacteria in water bodies. The cyanobacteria separation system is arranged on the hull of the separation ship. The cyanobacteria in the water body are collected by the feeding mechanism, and the cyanobacteria and water are collected together; the first filtration is carried out in the filter device, and the flocculant is added through the dosing device at the same time to dehydrate the cyanobacteria. The treated clean water is discharged into the water body through the first drain port, and the algae liquid is transported to the flotation tank; in the flotation tank, the cyanobacteria are dehydrated again by adding drugs through the dosing device, and then transported to the dehydrator; the dehydrator dehydrates the algae liquid, and the dehydrated cyanobacteria filter residue is packaged and collected, and the dehydrated filtrate is transported to the filter device again to be processed together with the newly collected algae liquid. Among them, the flocculation by adding drugs at the filter device is the first flocculation and is micro-flocculation, and the flocculation by adding drugs in the flotation tank is the second flocculation and is deep flocculation. Specifically:

[0022] A cyanobacteria separation vessel comprises a hull 1 equipped with a cyanobacteria separation system. The cyanobacteria separation system includes a feeding mechanism 2, which is located at the front end of the hull 1 to collect cyanobacteria from the water. The feeding mechanism 2 is connected to a filter device, which is connected to a flotation tank. After the filter device filters the water from the cyanobacteria, the algae liquid is discharged into the flotation tank for flocculation. The flotation tank is connected to a dehydrator, which dehydrates the flocculated algae liquid and packs the algae residue after dehydration. The dehydrator is also connected to the filter device, and the dehydrated filtrate is returned to the filter device for further filtration. A dosing device is also provided on the hull 1, connected to the filter device and the flotation tank, and can add chemicals to the filter device and the flotation tank in real time for flocculation.

[0023] The feed mechanism 2 includes a feed port 21 at the front end of the hull 1, as well as a first guide plate 22 and a second guide plate 23. The feed port 21 is equipped with a suction pump (not shown). The first and second guide plates 22 and 23 are horizontally arranged with their plates vertically arranged. One end of each is connected to the front end of the hull 1 and to either side of the feed port 21, and the other end is connected to a buoy 24. During operation, at least a portion of the first and second guide plates 22 and 23 are vertically below the water surface. The first and second guide plates 22 and 23 form a V-shaped opening, with the feed port 21 located at the smaller end of the V-shaped opening. In this embodiment, the opening size of the first and second guide plates 22 and 23 is adjustable and can be fixed after adjustment. The buoy 24 serves to increase the buoyancy of the first and second guide plates 22 and 23 to prevent the ends of the first and second guide plates 23 from being completely submerged during operation. During operation, as the hull 1 moves forward, the first guide plate 22 and the second guide plate 23 gather the blue algae at the front end of the hull 1. The blue algae are guided and gathered by the first guide plate 22 and the second guide plate 23 to the smaller end of the new V-shaped opening formed by the two; then they are sucked in by a suction pump (not shown in the figure) and transported to the filtering device.

[0024] The filtration device includes a first buffer tank, which is connected to the flotation tank. The algae liquid filtered by the filtration device first enters the buffer tank and then discharges into the flotation tank. The filtration device is provided with a first drain outlet, through which the clear water after filtering the cyanobacteria water is discharged. In this embodiment, the filtration device can be a graphene ultrafiltration device. The filtration device is connected to a dosing device, which adds flocculant to the filtration device to promote flocculation and dehydration of the cyanobacteria. The clear water filtered by the filtration device is discharged through the first drain outlet, and the filtrate is discharged into the first buffer tank. It should be noted that the degree of flocculation in the filtration device can be controlled by controlling the amount of flocculant added or the flow time of the algae water in the filtration device. The flocculation in the filtration device is micro-flocculation, and the dehydration rate of the cyanobacteria is 60%-70%. The discharged clear water can be considered to be free of residual cyanobacteria. The filtrate in the first buffer tank is transported to the flotation tank, and flocculant is added again through the dosing device for flocculation. This flocculation is deep flocculation, which further flocculates and dehydrates the cyanobacteria. After flocculation and dehydration in the flotation tank, the dehydration rate of the cyanobacteria can reach 80%.

[0025] The algae liquid flocculated in the flotation tank is transported to a dehydrator, which includes a second buffer tank connected to a filtration device. The dehydrated liquid is discharged into the second buffer tank and then into the filtration device. In this embodiment, the dehydrator can be a screw-type dehydrator. The dehydrated green algae can be packaged and collected, and the dehydrated filtrate is then recirculated to the filtration device. This secondary treatment ensures more effective separation of the blue algae.

[0026] Furthermore, it should be noted that in this embodiment, to improve the efficiency of cyanobacteria treatment, two cyanobacteria separation systems can be installed on the hull 1. These two systems can share the same dosing device. In the feeding mechanism 2, two sets of feed inlets 21 can be provided, with both sets of feed inlets 21 positioned between the first guide plate 22 and the second guide plate 23. In other words, the V-shaped opening formed by the first guide plate 22 and the second guide plate 23 can simultaneously close and feed the two sets of feed inlets 21, further improving the efficiency of cyanobacteria separation and treatment.
