Abstract

The invention discloses an alga cultivation device with indoor controllable cultivation conditions. A bottom plate is arranged at the bottom of an annular tank; a bearing is vertically connected with a rotating shaft; a rotating transverse arm is horizontally connected to the top of the rotating shaft; the rotating shaft is connected with an adjustable motor; the adjustable motor is connected with a speed regulator through a connection line; thrust blades are respectively vertically connected with two ends of the rotating transverse arm; the thrust blades are arranged inside a tank chamber of the annular tank; light sources are symmetrically arranged on two sides of the annular tank. The alga cultivation device has the advantages that temperature control and light control are achieved, and hydrodynamic condition experiments under different cultivation conditions are provided. In the alga cultivation process, the blades of the device rotate in a uniform speed, so that the problems that the flow speed is not stable, not uniform and the like are effectively solved.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation biology, in particular to an algae cultivation device with indoor controllable cultivation conditions. Background technique [0002] A large number of studies have been carried out on the causes and basic conditions of cyanobacteria blooms at home and abroad, and it has been found that the outbreaks of cyanobacteria blooms are generally closely related to many environmental factors such as the physiological characteristics of cyanobacteria, nutrients, temperature, light and other organisms. Among them, the hydrodynamic effect plays a role that cannot be ignored, and this effect is more significant in shallow lakes. Through the analysis of 12 typical cases of cyanobacteria outbreaks in Taihu Lake from 1986 to 2007, it was found that the water flow condition was one of the main inducing factors for the cyanobacteria outbreaks; some studies also reported that the flow of water in the l...
