Macro-algae breeding floating frame for adsorbing arsenic in seawater

Abstract

The present invention discloses a macro-algae breeding floating frame for adsorbing arsenic in seawater, which comprises a floating frame, a floating ball connected with the floating frame, a connecting standpipe with two closed ends, a piston rod, and a floating airbag. A buoyancy adjusting cavity is arranged in the floating frame. A unidirectional drain pipe is arranged on the bottom surface ofthe floating frame. The connecting standpipe passes through the floating frame, and both ends of the connecting standpipe protrude out of the floating frame. Water inlet holes are formed in the outerside wall of the connecting standpipe, below the floating frame; air inlet holes are formed in the outer side wall of the connecting standpipe, inside the floating frame; a high pressure gas pipe is connected with the outer side wall of the connecting standpipe, above the floating frame; the top end of the connecting standpipe is provided with an air outlet check valve. A first piston is arrangedin the connecting standpipe. One end of a piston rod is fixedly connected with the first piston, and the other end of the piston rod is fixedly connected with the floating airbag. The piston rod is sleeved with a first spring, between the first piston and the upper wall of the connecting standpipe. The macro-algae breeding floating frame for adsorbing arsenic in seawater has ingenious structure, can adjust ups and downs, has strong anti-wind-wave ability and great practical value, and is conducive to the stable growth and reproduction of macro-algae.

Description

technical field

[0001] The invention relates to a seaweed cultivation device, in particular to a floating frame for large algae cultivation used for absorbing arsenic in seawater. Background technique

[0002] With the development of the metal mining industry, a large amount of heavy metals such as arsenic, lead, zinc, cadmium, and copper are discharged into seawater. Once heavy metals are absorbed into the food chain, they will eventually accumulate in organisms and eventually endanger human health. Heavy metal pollution in the marine environment, especially in coastal waters, has become a problem that human beings must face all over the world. The large seaweeds (such as kelp, sargassum, etc.) that are common in the coast of my country have the ability to absorb arsenic, zinc, and cadmium because of their long body and fast growth. At the same time, they can purify harmful substances such as ammonia nitrogen, nitrite nitrogen, and phosphate in seawater. , is very suitable ...
