The joint research on the waste water purification was performed by Ishikawa
Agricultural Research Center, Ishikawa Prefectural Institute of Public
Health and Environmental Science, and Industrial Research Institute of
Ishikawa. Industrial Research Institute examined for decomposition of
cutting fluid waste of machining, dyeing liquid waste and surplus sludge.
The decomposition of the cutting fluid waste of machining and dyeing liquid
waste were conducted at high temperature and pressure water, and the decomposition
rate improved as much as temperature rose, and hydrogen peroxide added.
Furthermore, though the cooling liquid waste of machining for chlorine
was contained, it confirmed that dioxin was not occurred by high temperature
and pressure water treatment. The surplus sludge and organic chlorine
compound contained with the sludge could be decomposed by high temperature
and pressure water treatment.
