Water body blue algae treatment device
Technical Field
The invention relates to the technical field of water treatment equipment, in particular to a water body blue algae treatment device.
Background
When cyanobacterial bloom occurs in the water body, the commonly adopted treatment modes are chemical treatment and mechanical salvage treatment. The chemical treatment is to artificially administer chemical agents to kill algae or inhibit the growth of algae so that the amount of algae can be reduced or effectively controlled in a short time. The treatment method has quick response and is suitable for emergency treatment, but when the concentration of the medicament in the water body is reduced to a certain degree, the algae can continue to breed, and the long-term use of the chemical medicament can cause water body pollution and poison accumulation. The mechanical fishing mainly refers to collecting and fishing the blue-green algae in lakes and rivers by using a blue-green algae fishing boat, filtering and dehydrating the collected blue-green algae on the boat, and directly drying the blue-green algae into an algae cake.

After adopting the structure, compared with the prior art, the invention has the advantages that: can better collect and separate the blue algae on the water surface, and small in size. When the water body blue algae treatment device is used, the floating body can have different drafts on the water surface by adjusting the water inflow of the water pump, and the speed of the blue algae entering the collecting cylinder is well adjusted. Meanwhile, the blue algae is not stirred and smashed and can enter a collecting cavity of the separating device in a massive form, and the massive blue algae can rise at a very high speed and is convenient to clean. Thus, the excellent blue algae collecting effect is achieved. In addition, the collecting device and the separating device adopt a split design, so that the device can be made to be small and exquisite. For the water body blue algae treatment device which is prepared actually, the minimum occupied area can be less than 2 square meters, and the device is extremely suitable for water quality treatment of small-area water areas.

Detailed Description
Examples, see fig. 1-3: the water body blue algae treatment device comprises a collection device 10, a separation device 20 and a pipeline 30.
Specifically speaking:
the collecting device 10 comprises a floating body 11 which floats on the surface of the water when in use. The floating body 11 has an inner cavity 111 with an upper opening, a water inlet 112 is opened on the side wall of the inner cavity 111, and a grille 113 is arranged in the water inlet 112. Meanwhile, a collecting cylinder 12 is arranged below the inner cavity 111, and the lower end of the pipeline 30 is communicated with the lower part of the collecting cylinder 12.
The separation device 20 is typically placed on the bank of the river. The separating apparatus 20 comprises a separating chamber 21 and a water pump 22. The water pump 22 is necessarily connected to an electric motor (not shown) and the motor is preferably provided with a speed controller. That is, the pumping speed of the water pump 22 can be adjusted. A vertical partition plate 23 is arranged at the upper part of the separation cavity 21, a gap is formed between the partition plate 23 and the bottom of the separation cavity 21, and the separation cavity 21 is divided into a collection cavity 211 and a water outlet cavity 212 by the partition plate 23. That is, the collection chamber 211 is spaced from the lower portion of the outlet chamber 212 by a lower portion thereof. The upper end of the pipe 30 is connected to the water inlet end of the water pump 22, the water outlet end of the water pump 22 is connected to the collection chamber 211, and the collection chamber 211 is provided with an algae outlet 2111 at the upper part and a water return port 2121 at the middle or lower part of the water outlet chamber 212.
When the water pump 22 is used, water in the river channel starts to enter the inner cavity 111 through the water inlet 112 of the inner cavity 111, the floating body 11 descends, the inner water surface and the outer water surface of the inner cavity 111 have a certain water surface difference, and blue algae on the river channel flows into the inner cavity 111. Meanwhile, by adjusting the pumping speed of the water pump 22, the floating body 11 has a relatively balanced draft, thereby forming a balanced overflow. And under the pumping of the water pump 22, the mixture of the blue algae and the water rapidly enters the separation cavity 21 of the separation device 20, and the blue algae can rapidly float without being broken and can not enter the water outlet cavity 212 under the blocking of the partition plate 23. Finally, the separated blue algae flows out from the algae outlet 2111, the water flows out from the water return port 2121, and the water can flow into the river channel again after flowing out.
Optimizing:
the partition 23 is in the shape of a perforated strainer, or the partition 23 is provided with a plurality of water permeable holes (not shown). Therefore, the blue algae and the water can be more conveniently separated.
The upper part of the collection chamber 211 is provided with a push plate 24, and the push plate 24 is connected with an electric reciprocating device (not shown in the figure). Of course, the moving direction of the push plate 24 is necessarily a direction approaching and departing from the algae outlet 2111. Thus, the separated blue-green algae can be flowed out as quickly as possible.
