Title:
CONDENSING AND SOLIDIFYING TREATMENT METHOD AND SYSTEM FOR MISCELLANEOUS WASTE WATER FROM NUCLEAR POWER FACILITY AND THE LIKE
Document Type and Number:
Japanese Patent JP2005201730
Kind Code:
A
Abstract:

To surely and safely avoid corrosion of facilities in condensing and solidifying treatment of miscellaneous waste water by reducing a volume of miscellaneous waste water generated in the facility of nuclear power plant and the like in condensing treatment and drying to powder and solidified, and drastically reduce treatment cost after powder drying by raising the volume reduction ratio by condensing of miscellaneous waste water to maximum.

Miscellaneous waste water 11 stored in a drain tank 21 is transported to a condenser 22 and the volume is reduced in the condensing treatment by evaporation, and then it is transported to a waste liquid tank. The waste liquid in the waste liquid tank is dried to powder and is solidified by mixing with an admixture in the method of condensing and solidifying treatment of miscellaneous waste water. The condenser 22 is provided with an ion concentration detection means 22a for calculating a chloride ion concentration contained in the treatment water 12 in the condenser 22. When a chloride ion concentration over a specific value is detected with a monitor of the chloride ion concentration, the treatment water 12 in the condenser 22 is transported to the waste liquid tank 23.
