The reactor comprises a constant temperature water bath box and an internal box with the top open and arranged in the constant temperature water bath box, wherein a carbon fiber submersible heating line is coiled on the internal box circumferentially, the carbon fiber submersible heating line is connected with a temperature control switch arranged outside the constant temperature water bath box, a cover board is arranged at an opening of the internal box, the cover board is provided with a light emitting device andan aeration device, the light emitting device illuminates towards the interior of the internal box, the aeration device is communicated with an even aeration head in the internal box, a liquid inlettube and a liquid outlet tube are sequentially communicated with the side wall of the internal box from top to bottom, both the liquid inlet tube and the liquid outlet tube extend out of the constanttemperature water bath box, the light emitting device on the cover board comprises a plurality of LED light strips arranged at the bottom of the cover board and a single-chip microcomputer system arranged at the top of the cover board and used for regulating the illumination strength of the plurality of LED light strips. The light emitting device can be used for simulating periodic changes of accepting illumination strength by algae in a layered lake and reservoir internal wave state, so as to research a growth inhibition and stress adaptation mechanism for the algae.

Description

technical field [0001] The invention belongs to the field of pollution control of lakes, reservoirs, and ocean water bodies, and in particular relates to a reactor for simulating internal wave mixing to control algae, which is used to simulate periodic changes in light intensity received by algae under internal wave conditions by periodically changing light intensity, and then Quantitatively study the effect, mechanism and optimization conditions of technical application of internal wave algae control. Background technique [0002] In recent years, the eutrophication of lakes and reservoirs across the country has become serious, and the frequency and degree of algae outbreaks have increased. In summer, the surface temperature of the lake water body rises, forming a temperature gradient in the longitudinal section of the lake reservoir, in which the thermocline layer with a large temperature gradient prevents the natural vertical circulation of the water body, and the interna...

Problems solved by technology

At the same time, field research has also found that naturally formed internal waves (such as wind force) will cause the vertical reciprocating migration of algae inside the water body, thereby causing periodic fluctuations in factors such as temperature, light intensity, dissolved oxygen, and nutrient concentration where the algae are located. Among them, the light intensity decays exponentially with the increase of water depth, which leads to the greatest impact of light intensity on the growth of algae; however, in natural stratified water bodies, due to the complexity of the external environment and factors affecting the growth of algae, it is impossible to quantitatively judge the impact of internal waves on algae in water. The control effect and mechanism

In natural stratified water bodies, internal waves can also be artificially induced by underwater aeration or mechanical circulation, causing periodic fluctuations in algae growth conditions (especially light intensity), thereby inhibiting the growth of algae, but it cannot be predicted quantitatively Effect of artificially induced internal wave on algae control

If you want to use internal wave algae control in actual lake water eutrophication control projects, you need to conduct systematic research on its algae control effect, mechanism and optimization conditions; The fluctuating reactor makes it impossible to qualitatively and quantitatively study the principle and optimization conditions of the internal wave mixing algae control technology under the controllable conditions of the laboratory
