Method and device for simulating water bloom floatation of blue algae

Abstract

The invention provides a method and a device for simulating the water bloom floatation of blue algae, belonging to the field of water environment. The device comprises a reaction column, a light source and a heating sink, wherein the light source and the heating sink are arranged at the top of the reaction column; the top of the reaction column is sealed aseptically; the outer surface of the reaction column is provided with an aseptic aeration inlet, a culture liquid inlet, an aseptic stirring airflow inlet and a circulating water inlet; the middle of the reaction column is provided with a sampling inlet; and the lower part of the reaction column is provided with a circulating water inlet. The method comprises the following steps: carrying out the amplification culture of algae species; sterilizing culture fluid and a simulating device; placing the culture fluid in the reaction column; inoculating the blue algae into the reaction column for sealing; setting environmental conditions; and then, periodically sampling to analyze and observe the floating characteristics of the blue algae. The method enables the algae to grow in aseptic environments and can effectively simulate the water bloom of the blue algae. The device has simple structure, small size, easy operation, strong removability, indoor and outdoor use, corollary use with an illumination culture box, convenient manufacture and low cost.

Description

technical field [0001] The invention relates to a method and a device for simulating the occurrence of water blooms, more specifically a method and a device for simulating the floating of cyanobacteria blooms. Background technique [0002] With the rapid development of my country's economy and the acceleration of urban and rural construction, the discharge of pollutants such as nitrogen, phosphorus, and organic matter in areas along rivers and lakes has increased year by year, and the pollution of lake water environment has become increasingly serious, mainly manifested in eutrophication of lake water and cyanobacteria. At present, most of the five major freshwater lakes and urban lakes in the middle and lower reaches of the Yangtze River in my country have entered the stage of eutrophication, and some lake areas of Taihu Lake and Chaohu Lake have entered the stage of heavy eutrophication. [0003] Eutrophication of water body means that lakes and other water bodies receive e...

Problems solved by technology

The above studies show that researchers at home and abroad have conducted in-depth research on the mechanism of cyanobacterial blooms, but so far, the research on the key stage of cyanobacterial blooms-the floating stage has not been developed at home and abroad, which affects the cyanobacteria bloom.
