Problems solved by technology

Excessive water content not only brings great costs to the transportation of cyanobacteria, but also brings great difficulties to the final disposal of cyanobacteria
If such high-water bloom cyanobacteria are directly buried, they will occupy a large area and easily cause pollutant overflow and leakage. If they are directly processed for feed and fertilizer, large containers or facilities are required for detoxification and hydrolysis. Or decomposition, etc., the processing risk is high and the cost is high

Abstract

The invention discloses a method for controlling cyanobacteria bloom, which belongs to the technical field of water pollution treatment. The method for controlling the cyanobacteria bloom comprises the steps of: (1) utilizing an acquisition system with a sucking disk to perform suction acquisition on cyanobacteria on the water surface of a water body; (2) pumping cyanobacteria water which is subjected to suction acquisition into a conveying pipeline through a suction pump, and conveying the cyanobacteria water to a storage tank; (3) pumping the cyanobacteria water in the storage tank into a dosing system through a screw pump, adding a flocculating agent into the cyanobacteria water, and mixing evenly to ensure that the cyanobacteria is flocculated; (4) sending the cyanobacteria water with the flocculated cyanobacteria into a settling separation system for solid-liquid separation to obtain water and cyanobacteria mud with the water content of 80 percent, sending the water obtained after the solid-liquid separation to a clear water tank for temporary storage through the settling separation system, and then draining the water into the water body through an overflow port; and (5) separating the obtained cyanobacteria mud to obtain cyanobacteria mud with the water content less than 70 percent after the drying. The method for controlling the cyanobacteria bloom has the advantages of environmental protection, low cost and convenient operation, and can realize the safe disposal and resource utilization of the cyanobacteria bloom.

Description

technical field [0001] The invention relates to a method for controlling blue-green algal blooms, belonging to the technical field of water pollution control. Background technique [0002] Water bloom, also known as "water body eutrophication", is a natural phenomenon that occurs in fresh water. The high nitrogen and phosphorus content in the water body causes the sudden excessive proliferation of algae, and it is also a kind of secondary pollution. , The algae involved include cyanobacteria, green algae, diatoms, etc. When a bloom occurs, the water is usually green or blue in color. Naturally occurring algal blooms disappear quickly and have no environmental impact. In recent years, due to the rapid economic development and population surge, a large number of production and living pollutants have entered the water body, and too much nitrogen and phosphorus have been artificially discharged into the water body, making the eutrophication of fresh water exceed the environmen...
