CHLORINE AGENT FEED DEVICE TO BALLAST WATER, BALLAST WATER TREATMENT APPARATUS, METHOD FOR FEEDING CHLORINE AGENT TO BALLAST WATER, AND METHOD FOR TREATING BALLAST WATER

摘要

PROBLEM TO BE SOLVED: To provide a chlorine agent feed device to ballast water capable of subjecting the residual part of a chlorine agent aqueous solution to germicidal treatment, a method for feeding a chlorine agent, a ballast water treatment device using a chlorine agent aqueous solution as a bactericidal agent, and a ballast treatment method.;SOLUTION: Provided is a chlorine agent feed device comprising: a mixing dissolution device BMD where a solid chlorine agent is mixed and dissolved into water to produce a chlorine agent aqueous solution; a solution feed line 12 where the produced chlorine agent aqueous solution is fed to raw water for ballast water; and an alkali agent feed device ASDD where alkali agent is fed to the residual chlorine agent solution in the mixing dissolution device. The ballast water treatment device includes: a ballast water intake pipe line introducing the raw water into the ballast tank; a filtering apparatus included in the pipe line, filtering the raw water and capturing organisms in the raw water; a fungicide feed apparatus as the chlorine agent feeding apparatus of killing the organisms in the raw water after the filtering and sterilizing the bacteria; and a mixing apparatus included in the pipe line and mixing the fungicide into the raw water after the filtering.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
