Embodiment 1

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

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

[0033] Step 2, using ultrasonic waves to break the air sacs of algae in the algae-containing water flowing through the curved water tank, so that the algae sinks, and using ultrasonic waves to break the cell walls of the algae in the algae-containing water;

[0034] Step 3, input the algae-containing water after the ultrasonic treatment in step 2 into the flocculation reaction tank, and use the safe flocculant to carry out flocculation treatment;

[0035] Step 4. Input the algae-containing water after the flocculation treatment in step 3 into the flocculation-settling tank for settlement, and adjust the influent flow rate of the algae-containing water extracted in step 1 to make the settling time of the algae-containing water in the flocculation-settling tank For 2 to 4 hours, the precipitate and supernatant were obta...

Embodiment 2

[0038] Such as figure 1 , figure 2 As shown, a device for removing cyanobacterial blooms includes a hull 14, and also includes a pumping device 3, an ultrasonic treatment tank 6, a flocculation and stirring tank 9, a settling tank 11 and a power supply device, a pumping device 3, an ultrasonic treatment tank 6, and a flocculation and stirring tank. The pool 9, the settling tank 11 and the power supply device are all arranged on the hull 14, and the pumping device 3 extracts the water containing algae and enters it into the ultrasonic treatment pool 6, and the ultrasonic treatment pool 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 communicates with the pumping device 3, and the other end communicates with the flocculation stirring tank 8. A stirring impeller 21 is arranged in the flocculation stirring tank 9. The flocculation stirring tank 9 communicates with the settling tank...

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...
