Method for removing dormancy stage of blue algae and equipment thereof

Abstract

The invention provides a method for removing a dormancy stage of blue algae and equipment thereof. The method comprises the following steps: (1) absorbing the blue algae body in dormancy stage, dead algae body, partial clay mineral and water which are on the water-sludge interface onto a boat by a pump barrel through a suction nozzle in the dormancy stage of blue algae; (2) sufficiently separating the absorbed blue algae body in dormancy stage, dead algae body, partial clay mineral and water; and (3) returning the separated clay mineral and water to a lake body. The equipment for removing the dormancy stage of the blue algae used by the method is characterized by having the structure as follows: an inlet of a sludge pump is connected with a hose and the suction nozzle; an outlet of the sludge pump is connected with a filter; and an outlet of the filter is connected with a drainage port. The method and the equipment have the advantages that as algae outbreak has certain timeliness and stage, in the stage of algae non-outbreak, the algae are often enriched on the surface of sediment, mass outbreak of the algae can be effectively prevented through killing and blocking the algae body in the stage.

Description

technical field [0001] The invention relates to a method for removing the dormancy period of cyanobacteria, and the invention will also provide equipment used in the method. Background technique [0002] Among the various pollution problems of the lake water ecological environment, eutrophication is one of the most common and harmful prominent problems, which affects and restricts the coordinated development of the economy and society, and has become the most serious problem facing the world today. One of the main environmental problems of the world, and more and more people pay great attention to it. The greater the pollutant holding capacity of the water body, the sharp accumulation of pollutants in the water body and sediment, the higher and higher nutrient concentration, and the eutrophication of lakes is becoming more and more serious. The direct consequence of lake eutrophication is the overgrowth of algae and the degree of algae pollution is becoming more and more se...

Problems solved by technology

However, these algae suppression measures that have been researched and demonstrated are all carried out during the outbreak of algae blooms. Due to the extremely fast algae reproduction speed, the workload of removing algae is very large, so that the speed of algae removal cannot keep up with the speed of algae reproduction. Less than the purpose of effectively controlling cyanobacterial blooms
