Embodiment 1

[0024] Embodiment 1: (Chaohu, Anhui)

[0025] A kind of method utilizing trap to capture bloom cyanobacteria, its steps are:

[0026] A. Use foam plastic to make a 30cm circular buoy, and use waterproof cloth to process the cylinder to cover and reinforce it. Connect the foam plastic cylinder to a length of 100m. Set it as a bell-shaped guide area at the perennial downwind of Wannian Port, Chaohu, Anhui.

[0027] B. Set a movable fence horizontally at the bottom of the guide area 20m away from the bell mouth. When the wind blows the algal bloom into the bell mouth, the algal bloom can be harvested at the bottom of the bell mouth.

[0028] C. If the wind direction changes during harvesting, immediately pull a movable fence 20m away from the bottom of the bell mouth to the opposite end to close the trap, so that the algal blooms entering the bell mouth will not be blown out of the trap by the wind; Harvesting algal blooms continues inside the trap.

[0029] D. In order to pr...

Embodiment 2

[0030] Example 2: (Yunnan Erhai Lake)

[0031] A kind of method utilizing trap to capture bloom cyanobacteria, its steps are:

[0032] A. Make a Φ25cm circular buoy with foam plastic, and use a tarpaulin processing cylinder to cover and reinforce it. The foam plastic cylinder is connected to a length of 500m. It is set as a trumpet-shaped guide area at the perennial downwind of Shaping Bay, Erhai Lake, Yunnan. In order to prevent wind and waves from blowing and deforming the fence, an iron pile is drilled every 20m to fix the fence on the iron pile.

[0033] B. Set an area of ​​80m on the water surface at the bottom of the guide area of ​​the bell mouth 2 (10m×8m) Rectangular fence trap, after the wind blows the blue algae into the trumpet trap, the algal bloom can be harvested in the trap.

[0034]C. If the wind direction changes during the harvesting process, immediately pull the fence set at the bottom of the bell mouth to the opposite end to close the trap, so that the...

Embodiment 3

[0037] A device that utilizes traps to capture algal blooms, its connection relationship is as follows: According to Figures 1-3, it is made of foamed plastics into a circular buoy 3, processed into a cylinder with waterproof cloth, and the foamed plastics are made into a circular buoy 3 Put it into the tarpaulin cylinder, connect it to form a fence 1, set the fence into a bell mouth shape 2, set a movable fence 9 horizontally at 20m from the bottom of the bell mouth shape 2, and pull it to the opposite end to form a trap 8; or in the bell mouth shape 2 Set an area of ​​50-100m behind the bottom 2 Square or circular fence promptly constitutes trap 8, and when preventing from blowing, cyanobacteria bloom escapes from below floating fence, a high 50cm tarpaulin is set as skirt curtain 4 below floating fence, at the skirt curtain 4 lower ends every 5 Make a Ф2cm iron ring 5 at -10m, and connect the iron ring on the skirt curtain with the iron ring on the anchor 7 with the anchor ...

Abstract

The invention discloses a method and a device for capturing water bloom cyanophytes by using a trap. The method comprises the following steps of: A, arranging a floating fence to form a horn mouth shape at a perennial leeward port of a lake or a reservoir; B, arranging a movable fence at the position at a distance of 20 meters from the bottom of the horn mouth so as to form a trapezoid or square cyanophytes gathering trap at the bottom; C, when wind is blown to the inside of the horn mouth, opening the movable fence to make algal bloom enter the trap, when the wind is blown reversely, closing the movable fence to prevent the algal bloom entering the trap from being blown out by the wind, and capturing the cyanophytes at the bottom of the trap; and D, arranging waterproof cloth serving as a skirt curtain below the floating fence so as to prevent the algal bloom from escaping from the bottom of the floating fence, and straightening downwards and fixing the skirt curtain by using an anchor. The device for capturing the water bloom cyanophytes is characterized in that: a foam plastic cylindrical buoy is connected with the skirt curtain; the skirt curtain is connected with an iron hoop; and an anchor line is respectively connected with the iron hoop and the anchor. The device for capturing the water bloom cyanophytes has the advantages of easy method, simple and convenient operation, high efficiency of capturing the water bloom cyanophytes, simple structure, low price and high capturing efficiency. The method and the device are widely suitable for capturing the water bloom cyanophytes in the lake, the reservoir and the like.

Description

technical field [0001] The invention relates to the technical field of catching cyanobacteria in water blooms, more specifically to a method for capturing cyanobacteria in blooms by using traps, and also relates to a device for catching cyanobacteria in blooms by using traps, especially suitable for cyanobacteria in blooms in lakes and reservoirs Catch and collect. Background technique [0002] In recent years, due to the rapid development of industry, the rapid increase of population, the aggravation of urbanization, and the serious pollution of the environment, the degree of eutrophication in many water bodies in my country has intensified, causing a large number of algae, especially cyanobacteria, and even serious cyanobacteria blooms in some water bodies. , directly affects the quality and availability of water bodies, and endangers the health of livestock, poultry and human beings. A large number of cyanobacteria blooms in lakes and reservoirs in the middle and lower r...
