Embodiment
[0022] A device for removing blue-green algae in a water body and its use method, characterized in that: the device is composed of a water surface adsorption device and a supporting preparation, and the bottom of the water surface adsorption device is provided with a moving rope.
[0023] Described water surface adsorption device comprises melamine foam and sustained-release medicine box; Wherein, the bulk density of melamine foam is 20kg / m 3 , the porosity is 88%, the thickness is 7cm, the length is 1m, and the width is 0.5m.
[0024] The sustained-release medicine box is a cylinder with a bottom radius of 1.5cm and a height of 3cm, which is embedded in the bottom of the melamine foam. Two medicine boxes are evenly embedded under each foam board with an interval of 0.5m. PAC flocculation is put into the medicine box. Agents such as agents and PAM coagulants.
[0025] The supporting delivery preparations include organic acids, biodegradation enzymes and ferment bacteria, etc....

Abstract
The invention discloses a device for removing blue-green algae in a water body and a usage method of the device. The device comprises a water surface adsorption device 10 and matched release preparations 30, wherein a movable rope is arranged at the bottom of the water surface adsorption device 10; the water surface adsorption device 10 comprises melamine foamed plastic and a slow-release preparation box; the matched release preparations 30 comprise preparations such as organic acid, biological decomposition enzymes, enzyme microorganisms and the like. During usage, the matched preparations are released firstly, the pH of the water body is adjusted, decomposition of dead blue-green algae and impurities in water is assisted, then the water surface adsorption device is spread, the blue-green algae are collected and treated through physical flocculation and adsorption, the device is exposed to the sun after being taken back, and the device can be used repeatedly. With the adoption of the device, high-efficiency treatment of the blue-green algae is realized, the cost is low, and pollution is avoided.
Description
technical field [0001] The invention relates to the technical field of water cleaning, in particular to a device for removing blue-green algae in water and a method for using the same. Background technique [0002] With the rapid development of the economy, human beings are becoming more and more dependent on water resources. However, poor water management and long-term use of chemical fertilizers and other easily lost nutrient substances have led to the trophication of water in lakes. One of the major environmental problems we are facing is the outbreak of cyanobacteria blooms, a prominent problem brought about by the trophication of water bodies. Large-scale cyanobacteria blooms reduce the utilization efficiency of water resources, causing serious ecological damage and huge economic losses. The production of toxins has brought great hidden dangers to public safety and health. [0003] Cyanobacteria are a class of extremely ancient and tiny prokaryotes. Long-term evolution...
