Embodiment 1

[0030] The red tide emergency repair methods include:

[0031] 1. Fish the algae-containing water body in the water body where the red tide occurs, pass the algae-containing water body into the sealed tank, and add the medicament to the sealed tank, the top of the sealed tank is provided with a vacuum pump for reducing the air pressure in the sealed tank, and at the same time Turn on the ultrasonic device provided on the outer wall of the sealed tank for ultrasonic treatment, and the medicament is hydrogen peroxide;

[0032] 2. After reacting in the sealed tank for 120 minutes, turn on the sludge pump at the bottom of the sealed tank to extract the algae slurry deposited at the bottom of the sealed tank into a centrifuge for centrifugation, and send the algae residue to the carbonization furnace to produce algae carbon. The supernatant Then it is transported to the sealed tank for recycling;

[0033] 3. Circular treatment between the sealed tank and the centrifuge, the concen...

Embodiment 2

[0038] The invention is used to investigate the removal effect of algae in the culture solution.

[0039] Take the algae-containing liquid and pass it into the sealed tank, add 30% mass concentration of hydrogen peroxide solution, control the concentration of hydrogen peroxide at 0.5% mass concentration, H 2 o 2 with Fe 2+ The molar ratio is 10:1, and the algae removal rate is 94.3% after sealed tank and centrifugation treatment.

Embodiment 3

[0041] The invention is used to investigate the removal effect of algae in the culture solution.

[0042] Take the algae-containing liquid and pass it into the sealed tank, add 30% mass concentration of hydrogen peroxide solution, control the concentration of hydrogen peroxide at 0.8% mass concentration, H 2 o 2 with Fe 2+ The molar ratio is 10:1, and the removal rate of algae is 96.5% after sealed tank and centrifugation treatment.

Abstract

The purpose of the present invention is to provide a red tide emergency repair method, which uses the addition of medicament in the sealed tank, cooperates with the negative pressure environment in the sealed tank, reduces the boiling point of the liquid in the tank, generates water vapor to increase the concentration in the sealed tank, and makes the sealed tank The algae in the algae are broken, and then the broken algae are transported to the centrifuge for centrifugation, and the centrifuged liquid is returned to the sealed tank, and the negative pressure concentration is continued, and finally the material in the algae is left in the sealed tank, and the The crushed algae are sent to the carbonization furnace for carbonization treatment to produce algae carbon and prevent secondary pollution caused by nitrogen, phosphorus and algae toxins in the water body.

Description

technical field [0001] The invention relates to a method for repairing polluted seawater, in particular to an emergency repair method for red tides. Background technique [0002] Red tides are caused by the excessive flow of land-based sewage containing nitrogen and phosphorus into the sea, which produces excessive red tide microorganisms, that is, algae. This kind of algae generally reproduces in large numbers on the surface of the water at a depth of about 1 meter, causing insufficient oxygen in the water, and due to the decomposition of dead algae to form toxins, it will cause a large number of marine organisms such as fish and shellfish to die, causing huge losses to fishery production. [0003] When the red tide occurs, the method of spreading loess is commonly used. After using the loess, the algae will settle and rot on the coast, which will cause secondary pollution of sea water quality. CN201136798Y adopts a physical method to remove blue-green algae in the water b...
