Problems solved by technology

[0006] At present, there are mainly three types of power used in the test: electric agitator, water pump and mechanical water deflector. Small, so that local differences have a greater impact on the overall test results
[0007] (3) Lack of systematic research on the mechanism of water flow affecting algae growth
Its shortcoming is that the structure is complex, and the side wall has a great influence, which affects the detection of algae indicators in the water body.

Embodiment Construction

[0027] The present invention takes the influence mechanism of hydrodynamics on Microcystis aeruginosa as the research object, on the basis of literature research and experimental method optimization, adopts the method of combining small-scale test and model test, indoor test and outdoor verification, from the growth of Microcystis aeruginosa Starting from the physiological characteristics, systematic research was conducted on the mechanism of the influence of water flow on Microcystis aeruginosa. The research results not only perfected the theory of water flow dynamics controlling the occurrence of algae blooms, but also filled the gap in the research on the mechanism of water flow dynamics on algae growth. Provide key technical support for the occurrence of algae blooms in trophic water bodies and to improve the landscape value of water bodies.

[0028] Below with reference to accompanying drawing and preferred embodiment, technical scheme of the present invention is described...

Abstract

The invention discloses a microcystis aeruginosa research device which comprises a water tank, a motor and a lighting system, wherein the water tank is in the shape of an annular column with an upward opening; the motor is arranged in the center of circle of the water tank; an output shaft of the motor is provided with vertical supporting beams; the top ends of the supporting beams are provided with horizontal suspension arm beams; water pushing sheets are arranged below the suspension arm beams and extend into the water tank; and the lighting system is arranged at the periphery of the water tank. The device has the characteristic that a water body has basically consistent flow velocity during an experiment.

Description

technical field [0001] The invention relates to a biological research device, in particular to a research device for Microcystis aeruginosa. Background technique [0002] From the research results in recent years, there is a certain relationship between the flow velocity and the speed of algae blooms. It has been fully verified that increasing the flow velocity can effectively inhibit the occurrence of algae blooms, but there are great differences in the critical velocity values. From the perspective of the research process, the current experimental research generally has the following problems: [0003] (1) The test scale is small. [0004] According to the existing experimental research, most of the test devices use baffle pools, the flow channel width is about 0.1-0.4m, and the water depth is mostly 0.1-0.5m. The data is relatively small, and at the same time, due to the small difference in light conditions between the surface and the bottom of the water body, it is dif...
