Abstract

The invention relates to a watershed cyanobacteria bloom, extinction and aggregation simulation culture device and aims at solving the technical problem that simulation and study on the influence factors of watershed cyanobacteria bloom, extinction and aggregation are difficult. The watershed cyanobacteria bloom, extinction and aggregation simulation culture device comprises a lake body module, aninput diversion pipe and a low-concentration algae liquid tank; the lake body module is further internally provided with a stirring assembly, an oxygen control assembly, a light temperature control assembly and an aeration assembly; one end of the input diversion pipe is used for inputting river water; the input pipe is provided with a flow controller; and the other end of the input diversion pipe communicates with the lake body module through multiple branch pipes. By adopting the watershed cyanobacteria bloom, extinction and aggregation simulation culture device disclosed by the invention,through a certain time, in the process that low-concentration algae liquid flows from the low-concentration algae liquid tank to an algae liquid recovery bucket through the lake body module, the influence of a temperature on the reproduction state of cyanobacteria can be obtained by changing different illumination intensities of a lake body; and the influence of different water flow speeds on bloom, extinction and aggregation of the cyanobacteria can be obtained by changing the water flow speed in the lake body with stirring.

Description

technical field [0001] The invention relates to a simulated cultivator for the accumulation of cyanobacteria in watershed blooms. Background technique [0002] At present, algae bloom is one of the most prominent worldwide water environmental problems, and it is becoming more and more serious with the development of the global economy and the expansion of the impact of human activities. The phenomenon of cyanobacteria is particularly serious in our country. Algae blooms occur to varying degrees in most rivers, lakes, and even reservoirs. Lakes such as Taihu Lake, Dianchi Lake, and Chaohu Lake have outbreaks of algae blooms from time to time. The phenomenon of algal blooms occurs frequently over a large area and for a long time, which not only destroys the function of the lake and the ecological environment, but also threatens the safety of human health and drinking water. It has become one of the main environmental problems that plague the sustainable development of China's ...
