Description

Technical Field

[0001] The invention belongs to the field of marine aquaculture, and in particular relates to a method for treating nuclear contaminated water in a marine aquaculture farm by utilizing seaweed adsorption. Background Art

[0002] Radioactive substances in nuclear wastewater may cause long-term and far-reaching damage to the ecological environment of aquaculture farms through the transmission of ocean currents and food chains. These radioactive substances will accumulate in marine organisms, destroy their genetic material and physiological functions, and thus affect the balance of the entire ecosystem. Radioactive substances have a direct negative impact on the growth, reproduction and survival of farmed organisms such as fish and shellfish. They may cause deformities, death or slow growth of organisms, thereby reducing aquaculture output and quality. Due to the impact of nuclear wastewater pollution, consumers may have a crisis of confidence in aquatic products from polluted waters, leading to a decline in market demand. This will cause direct economic losses to the marine aquaculture industry and may trigger a chain reaction, affecting the healthy development of the entire industry chain.

[0003] There are currently no patents related to marine nuclear wastewater treatment for marine aquaculture farms. The current nuclear wastewater treatment technologies at home and abroad have the problems of high cost, poor effect, and cannot adapt to the marine environment. Summary of the invention

[0004] The object of the present invention is to provide a method for treating nuclear contaminated water in a marine aquaculture farm by using seaweed adsorption, which can realize automatic delivery of adsorption materials and meet the need for filtering nuclear elements.

[0005] A method for treating nuclear contaminated water in a marine aquaculture farm by using seaweed for adsorption comprises two parts: the moving in of a seaweed box and the replacement of the seaweed box. When no nuclear contamination is detected, the device does not put in the box. At this time, the entire adsorption dam operates normally and does not adsorb nuclear elements. Large particles of garbage and rocks are filtered by the filter tanks at the front and rear ends. The seaweed box is moved in: when nuclear contamination is detected, an unmanned boat carries the box to the entrance of the adsorption dam. After arriving at the designated position, the unmanned boat extends a downward conveyor belt guide rail to transport the seaweed box to the set position. The float is deflated, and the seaweed box sinks to the track. The seaweed box is controlled by a time relay to move forward a distance of a box for the next filling, and this is carried out in sequence until the inside of the adsorption dam is filled with the box.

[0006] Seaweed box replacement: When performing seaweed box replacement operations, the unmanned boat moves to the seaweed box exit, extends the downward conveyor belt guide rail, inflates the float, and puts the seaweed box to be replaced into the conveyor belt track, and moves to the unmanned boat through the bottom guide rail. The seaweed box remains stationary on the unmanned boat and the guide rail is retracted.

[0007] Furthermore, it also includes a processing device, which includes an adsorption dam body, an unmanned boat and an automatic control module of the device; filter tanks are installed at the front and rear ends of the adsorption dam body and are connected by a bottom guide rail; a seaweed box is arranged on the unmanned boat; the unmanned boat transports the seaweed box to the adsorption dam body through a conveyor belt guide rail; the automatic control module of the device includes a time relay and a photoelectric sensor.

[0008] Furthermore, the seaweed box is provided with a plurality of water-permeable holes, and adsorption materials are placed inside the seaweed box.

[0009] Furthermore, the seaweed box is provided with a float, and the buoyancy is controlled by inflation and deflation.

[0010] Furthermore, the adsorption dam body is enclosed by a fixing plate, and the fixing plate is made of stainless steel.

[0011] Furthermore, the seaweed box in the adsorption dam body moves in the following manner: the photoelectric sensor is powered on, the conveyor belt starts to rotate, the rear box is moved forward along the bottom guide rail to the top and stops, the photoelectric sensor is powered off, and a gap is left at the entrance.

[0012] Furthermore, it also includes the process of moving in a new seaweed box: the photoelectric sensor is energized, the unmanned boat extends the downward conveyor rail, the float on the seaweed box is deflated, and the new box is slid along the slide rail into the adsorption dam through a chain drive, the rail is retracted, and the unmanned boat sails away to complete the replacement.

[0013] The beneficial effects of the present invention are:

[0014] (1) The linkage structure adopted by the present invention as a whole has strong bearing capacity and simple structure, and has good mechanical stability, which can ensure that multiple automated replacements will not cause structural problems and failures.

[0015] (2) The present invention realizes the complete automation of the replacement of the adsorption material and has good adaptability to seawater aquaculture farms. The overall structural design can assist seawater aquaculture farms in filtering pollutants and can achieve the effect of automated control.

[0016] (3) The control scheme adopted by the present invention is simple to implement and can effectively reduce the labor required for replacing the box body, thereby automating the adsorption material replacement process. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described below in conjunction with the accompanying drawings.

[0022] The present invention realizes the adsorption of nuclear elements and the automatic replacement of adsorption materials in seawater aquaculture farms. The device is mainly structured with chain and gear transmission. The entire deployment and recovery process is controlled by a motor. The motor can be controlled and remotely controlled by a time relay and a photoelectric switch to realize automatic deployment and recovery of adsorption materials, filling the gap of patents for nuclear element adsorption and automatic replacement of adsorption materials in seawater aquaculture farms.

[0023] like Figure 1 As shown, in order to realize the automatic delivery of adsorption materials and meet the needs of nuclear element filtering at the same time, the present invention provides a nuclear contaminated water treatment device and treatment method for seawater aquaculture farms using seaweed adsorption. The automatic replacement main body is an unmanned boat 4, which carries an adsorption seaweed box 3. The hull and the box are made of alloy steel. The hull is provided with an extendable conveyor belt guide rail 5 for box transportation and replacement. The bottom is composed of a bottom guide rail 6. The unmanned boat 4 and the adsorption dam body 1 are driven by a chain to control the movement and replacement of the seaweed box. The motor controls the switch and forward and reverse rotation through a time relay and a photoelectric sensor (a in the figure). The seaweed box 3 equipped with a float 8 adjusts the buoyancy of the box by inflating and deflating air, so that the box can achieve better transmission through the change of buoyancy.

[0024] When no nuclear contamination is detected, the device does not drop the box. At this time, the entire adsorption dam operates normally and does not adsorb nuclear elements. The filter tanks 2 at the front and rear ends filter out large particles of garbage and stones. When the device detects nuclear contamination, the unmanned boat 4 carries the box containing the adsorption material to the adsorption dam (A in the figure) for filling.

[0025] Seaweed box filling process: Utilizing the biological enrichment effect of living seaweed, treated kelp is used as adsorption material and filled into the box to adsorb nuclear elements in nuclear contaminated water.

[0026] The process of moving the seaweed box in: when nuclear contamination is detected, the unmanned boat 4 carries the seaweed box 3 to the entrance of the adsorption dam. After arriving at the designated position, the boat extends a downward conveyor guide rail 5 to transport the box to the set position. The float 8 on the box is deflated to reduce the buoyancy, and the seaweed box 3 sinks to the track. The gear transmission device is energized and the box is controlled to move forward a distance of one box through a time relay for the next filling, and this process is repeated in sequence until the interior of the adsorption dam 1 is filled with boxes.

[0027] Seaweed box replacement process: When performing the seaweed box 3 replacement operation, the unmanned boat 4 slowly moves to the box exit (B in the figure), extends a downward conveyor guide rail 5, and the float 8 on the seaweed box 3 is inflated to increase the buoyancy of the box, so that the seaweed box to be replaced enters the conveyor track and moves to the unmanned boat 4 through the bottom guide rail 6. The box remains stationary on the unmanned boat 4 and the guide rail is retracted.

[0028] The box body moves inside the adsorption dam body 1: the photoelectric sensor is powered on, the conveyor belt starts to rotate, and the box body behind is moved forward along the bottom guide rail 6 to the top and stops, the photoelectric sensor is powered off, and a gap is left at the entrance.

[0029] The new seaweed box is moved in: the photoelectric sensor is powered on, the unmanned boat extends a downward conveyor guide rail 5, the float 8 is deflated to reduce the buoyancy of the box, and the new box is slid into the adsorption dam body 1 along the slide rail through the chain drive, the guide rail is retracted, and the unmanned boat sails away to complete the replacement.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
