Title:
METHOD FOR STERLIZING SEAWATER
Document Type and Number:
Japanese Patent JP3740562
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To sterlize poisonous phytoplankton to protect cultured shellfishes by hanging a rope into the sea, which rope is interwoven with a titanium electrode, a stainless steel electrode and the like and effecting electroanalysis of seawater as well as generating electric shock by electric power from a solar light electric conversion device.
SOLUTION: A rope is hanged under the surface of the sea 2 from a marine buoy 1 and a positive electrode 5 and a negative electrode 6 using a titanium electrode and the like are installed to sterlize phytoplankton 4 which can kill cultured shellfishes 3 or produce shellfish poisons. The positive electrode 5 and the negative electrode 6 are connected to a solar light electric conversion device 7 and a constant-current battery 8 by a wire 9 and are energized. Then, a low concentration of sodium hypochlorite 10 is produced between the positive electrode 5 and the negative electrode 6, and therefore, only the phytoplankton 4 is sterlized and subjected to electric shock without causing death of the cultured shellfishes. Thus, shellfish poisons are made harmless and safe shipment of the cultured shellfishes becomes possible.
