Embodiment Construction

[0018] Hereinafter, the embodiment of the processing method of the marine living resource of this invention is described in detail.

[0019] This method of processing marine living resources is a method of processing marine living resources containing seaweed or shellfish mixed in when sea water is taken, such as figure 1 As shown, the following steps are included: a heating step S1 of heating the water-containing marine living resources; a mixing step S2 of mixing a heavy metal insoluble agent in the water-containing marine living resources; and a drying step S3 of drying the mixture after the mixing step S2. Here, the term "moisture-containing marine living resources" refers to marine living resources in a state where seawater or flushing water adheres without drying.

[0020]

[0021] The heating step S1 is a step of heating the marine living resources in a water-containing state, and is carried out in order to promote the elution of heavy metals contained in the marine l...

Abstract

An object of the present invention is to provide a method for processing marine living resources capable of relatively easily producing marine living resources in which the amount of elution of heavy metals is suppressed. The present invention is a method for treating marine living resources including seaweeds or shellfish mixed with seawater when drawing water, comprising a step of mixing a heavy metal insoluble agent with the aforementioned marine living resources containing water, and drying the mixture after the mixing step. process. This method of processing marine living resources may further include a step of heating the above-mentioned marine living resources containing moisture before the above-mentioned mixing step. The above-mentioned marine living resources may contain arsenic. The above-mentioned heavy metal insolubilizer may be iron powder.

Description

technical field [0001] The invention relates to a processing method for marine biological resources. Background technique [0002] Seawater is used for raw materials such as salt and alkali metals, domestic water, ballast water, and cooling water. When obtaining seawater, various marine living resources may be mixed depending on the time of drawing water and the place of drawing water. Seaweeds and shellfish are examples of marine living resources mixed with seawater at the time of water intake. [0003] These marine biological resources mixed with sea water are generally treated as industrial waste. When marine biological resources are treated as industrial waste, the marine biological resources are dried for the purpose of reducing volume and suppressing decay. [0004] Seaweed is known to contain a large amount of arsenic, and shellfish meat, viscera, or midgut glands (ウロ) contain arsenic, cadmium, hexavalent chromium, and the like. In addition, when the arsenic conte...
