Embodiment Construction

[0010] Referring to Fig. 1, in order to prevent microalgae from accumulating on the lower surface of the flexible belt due to the disturbance of the water layer in stormy water, the algae collection tank is prepared with baffles 15 on both sides and a slag blocking net 3 at the front end. The back end is an open structure, which makes the water in this area calmer. The algae collection tank is installed on the top of the floating tank 11, and the floating tank 11 is equipped with a water inlet 8, a water outlet 9 and an air inlet and outlet 10, and the water outlet 9 is connected with a pump (not shown). In the deeper water layer, open the solenoid valve to let the water enter the buoyancy tank 11 from the water inlet 8, so that the algae collection tank can sink; on the contrary, when the water is shallow, the pump can be started to discharge the water in the buoyancy tank 11 from the outlet 9 , the air inlet and outlet 10 enters the air to float the algae collection tank. I...

Abstract

The invention relates to a water-body microalgae enriching method and device, especially a wave-canceling multilayer microalgae enriching method and device, limiting water body for collecting microalgae in a algae collecting tank with baffle plates on two sides, residues blocking net at the front end and a notch at the back end, installing annular inflective, layered and flexible tape in the tank, driving by electric motor to move each layer of microalgae nearby the baffle plates for enriching, and then pumping away the microalgae. The invention has simple device structure, high alage obtaining efficiency, and low energy consumption and is not affected by wind and wave as working in a large-scale natural water body.

Description

technical field [0001] The invention relates to a method and device for enriching microalgae in a water body, in particular to a method and device for enriching microalgae in multi-layered waves, belonging to the field of environmental protection sewage treatment; meanwhile, it is also suitable for enriching beneficial microalgae in water bodies. technical background [0002] Over the years, the eutrophication of large natural water bodies due to severe environmental pollution has directly led to the proliferation of algae, especially cyanobacteria, which has seriously affected the quality of water bodies; on the other hand, due to the strong nitrogen, phosphorus and organic Concentration of pollutants. Therefore, the capture of cyanobacteria is of special significance to the purification of heavily polluted water bodies. Many researchers and research units both at home and abroad are seeking effective methods for harvesting blue-green algae. There have been existing method...
