Dynamic microcosm system device for simulating lake ecosystem

Abstract

The invention belongs to water body ecology drainage basins, and particularly relates to a dynamic microcosm system device for simulating a lake ecosystem. The rainfall simulation system specifically comprises a water storage unit, a rainfall control unit, a lifting pump and a straight pipe, the water storage unit and the straight pipe are connected through a conveying pipeline, the lifting pump is arranged on the conveying pipeline, the lifting pump is electrically connected with the rainfall control unit, and the rainfall simulation system can be used for receiving feedback signals of the rainfall control unit to adjust flow. According to the invention, the lake ecosystem can be truly restored, and the dynamic influence on the water body can be reflected by simulating the change of the environment variable in a certain interval; a relatively complete ecological chain capable of satisfying simultaneous survival of water, mud and organisms is constructed, and sufficient contact between the organisms and the environment is ensured; meanwhile, multiple weather activities and disturbance of the weather activities to the water body can be simulated through the rainfall control unit, and compared with static changes in the prior art, dynamic simulation of a natural environment system is achieved.

Description

technical field [0001] The invention belongs to water body ecology basin, in particular to a dynamic microcosm system device for simulating a lake ecosystem. Background technique [0002] Most lakes around the world are polluted to varying degrees, especially eutrophication. Direct research on various pollution phenomena in lakes often has shortcomings such as inconvenient observation and difficult control of experimental conditions. Microcosm, also known as model ecosystem, refers to the use of biological models of natural ecosystems to simplify complex and heterogeneous natural ecosystems and simulate their processes to obtain various quantitative data (such as the impact of energy and nutrient flow on corrupted data, etc.). The water ecosystem can be simulated by using the microcosm system, and the relatively complete eutrophication and other pollution processes can be simulated by constructing the water body-biology-sediment ecological chain. However, the existing aqu...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the biological composition that can be simulated by the microcosm system is relatively simple, which cannot meet the growth environment of fish, submerged plants and emergent plants, and cannot control dissolved oxygen and flow rate.

Its shortcoming is that: too much interference between different organisms and environmental media is removed, and the interaction between organisms is ignored, such as the sediment disturbance that fish can cause, etc., and the real water environment cannot be simulated.

Its shortcoming is that the only environmental elements that can be controlled are temperature and light, and the water body data that can be monitored online and the environmental conditions that can be simulated are less

Its shortcoming is that it can only form turbulent flow, but its size and direction cannot be changed, and the size and direction of the moving speed of any point in the water body will have a turbulent flow.

Not only that, the water body simulated by the device is in a constant state, which cannot reflect the dynamic impact of real-time changes in environmental variables on the water body
