Embodiment 1

[0076] Embodiment 1. Field test of shading influence

[0077] The experiment was carried out in a storage pool for irrigation water in a flower garden in the suburbs of Wenzhou City [3] . The pool is 25m long, 15m wide, 1.2-1.8m deep, and has a total water storage capacity of 562.5m 3 . The pool water is in a state of severe eutrophication, and microscopic examination revealed that the dominant algal species in the water is Coelomococcus indeterminate.

[0078] The shading material adopts commercially available polyethylene sunshade nets with shading rates of 70% and 85%. A number of nylon ropes were fixed horizontally on the water surface, and sunshade nets were laid on top. Two layers of sunshade nets with a shading rate of 70% were laid on the 1st to 6th d, and a layer of sunshade nets with a shading rate of 85% was added on the 6th to 9th d.

[0079] The test was carried out in early September 2006. The 0th to 1st days were cloudy with rain, and the 2nd to 9th days wer...

Embodiment 2

[0086] Embodiment 2. Effect of shading and cooling on water body algae density

[0087] In order to determine the influence of solar panel shading and refrigeration sheet cooling on the growth of algae in water, a three-dimensional water flow temperature mathematical model and a general water ecological model were used for simulation calculations.

[0088] (1) The effect of cooling of the cooling plate on the water temperature

[0089] 1) Mathematical model establishment

[0090] The range of water area simulated by the mathematical model follows the pool in Example 1, with a length of 25 m, a width of 15 m, and a water depth of 1.2 to 1.8 m. A single 18V50W solar panel with a size of 670 (length) × 540 (width) × 30 (thickness) mm is used, which is placed on the floating body frame on the water surface in turn, forming 36 × 27 solar panels on the water surface to block the light.

[0091] The calculation grid of the mathematical model is divided into 36×27 grids horizontally...

Abstract

The invention discloses a blue-green algae growing and inhibiting device with solar cooling and shading functions and a use method of the blue-green algae growing and inhibiting device. The device isarranged on a floating body framework, wherein a solar panel is fixedly arranged on the floating body framework; a semiconductor chilling plate is arranged at a position, close to the water surface, of the lower part of the solar panel; a cooling rod is arranged below the semiconductor chilling plate and transfers cooling capacity generated by the semiconductor chilling plate into water for reducing the temperature of a water body; the solar panel is simultaneously constructed into a light shading plate. The blue-green algae growing and inhibiting device disclosed by the invention takes solarenergy as a power supply and combines the semiconductor chilling plate, the cooling rod and shading of the solar panel for application. The blue-green algae growing and inhibiting device is based on the characteristics of algae outbreak at illumination when the temperature is increased and takes solar energy as power; the semiconductor chilling plate is adopted to reduce the temperature of the water body, realizes the effects of reducing the temperature of the water body and the illumination, and destroys environmental conditions of the algae outbreak, thereby achieving the effect of inhibiting the algae outbreak. The blue-green algae growing and inhibiting device disclosed by the invention overcomes the defects of traditional technologies and can obviously inhibit algae growth.

Description

technical field [0001] The invention relates to a device and method for inhibiting the growth of algae, in particular to a cyanobacteria growth inhibiting device using solar energy as a power source, semi-conductor refrigerating sheet cooling to reduce water temperature and solar panel shading, and a method for using the device. Background technique [0002] Cyanobacteria are widely distributed, fast-growing algae. With the deepening of water pollution, blue-green algae often flood and grow in various waters, and even blue-green algae outbreaks occur. The overgrowth of blue-green algae decays in large quantities, causing black and odorous water bodies, and has become a common source of secondary pollution. In many public waters, especially in urban water sources, how to inhibit the growth of cyanobacteria and further control cyanobacteria pollution has become a technical problem. The cyanobacteria control method in the prior art has: [0003] 1. Physical algae removal met...
