Example Embodiment

[0030] Example 1

[0031] A method for removing cyanobacteria blooms, including the following steps:

[0032] Step 1. Extract the algae-containing water into the curved water tank;

[0033] Step 2. Use ultrasonic waves to break the air sacs of algae in the algae-containing water flowing through the curved water tank, so that the algae sink, and at the same time use ultrasonic waves to break the cell walls of the algae in the algae-containing water;

[0034] Step 3. Input the algae-containing water after ultrasonic treatment in step 2 into the flocculation reaction tank, and perform flocculation treatment with a safe flocculant;

[0035] Step 4. Input the algae-containing water that has undergone the flocculation treatment in step 3 into the flocculation sedimentation tank for sedimentation, and adjust the influent flow of the algae-containing water extracted in step 1 to make the sedimentation time of the algae-containing water in the flocculation sedimentation tank 2~4 hours to get th...

Example Embodiment

[0037] Example 2

[0038] Such as figure 1 , figure 2 As shown, a device for removing blue-green algae blooms includes a hull 14, a water pumping device 3, an ultrasonic treatment tank 6, a flocculation stirring tank 9, a settling tank 11, and a power supply device, a water pumping device 3, an ultrasonic treatment tank 6, and a flocculation stirring device. The tank 9, the settling tank 11, and the power supply device are all set on the hull 14. The pumping device 3 extracts algae-containing water and input it into the ultrasonic treatment tank 6. The ultrasonic treatment tank 6 includes a curved water tank and ultrasonic emission devices arranged on both sides of the curved water tank 17. One end of the curved water tank is connected with the pumping device 3, and the other end is connected with the flocculation and stirring tank 8. The flocculation and stirring tank 9 is provided with a stirring impeller 21, the flocculation and stirring tank 9 is connected with the settling ...

Abstract

The invention discloses a method for removing cyanobacterial bloom, comprising the following steps of: drawing algae-containing water into a curved water channel; breaking bladder of algae in the algae-containing water flowing through the curved water channel by the utilization of supersonic wave so as to make the algae sink and simultaneously breaking the cell wall of the algae in the algae-containing water by the utilization of supersonic wave; inputting the algae-containing water which has undergone ultrasonic treatment during the step 2 into a flocculation reaction tank and carrying out flocculation treatment by the use of a safe flocculating agent; inputting the algae-containing water which has undergone flocculation treatment during the step 3 into a flocculation settler for settlement so as to obtain a sediment and a supernatant; and discharging the supernatant. The invention also discloses an apparatus for removing cyanobacterial bloom. The apparatus contains a water pumping device, an ultrasonic treatment pool, a flocculation stirring pool, a settling basin and a power supply device. The method provided by the invention is easy to operate. The apparatus provided by the invention can be used to remove cyanobacterial bloom more thoroughly and efficiently, effectively purify the algae-containing water and effectively minimize nutrients in water, and can operate without maintenance for a long time.

Description

technical field [0001] The invention relates to the field of ecological treatment, more specifically to a method for removing cyanobacteria blooms, and also to a device for removing cyanobacteria blooms, which is suitable for improving landscapes and water environments polluted by cyanobacteria blooms. Background technique [0002] The increasingly serious eutrophication phenomenon causes a large number of cyanobacteria blooms in inland water bodies to accumulate on the surface of the water body, seriously affecting the water body landscape, and the algae toxins and odorous substances released by it seriously damage the water quality, endangering human health and social security. Continuous development. In order to eliminate algae blooms, many experts at home and abroad have invested many years of efforts to study a variety of methods to control the outbreak of algae blooms, such as physical methods, chemical methods, mechanical methods, biological manipulation methods, ecol...
