Abstract
PURPOSE: To reuse waste water as flushing one by adjusting the pH of the wate water to a specific value by removing fluoric acid without increasing salt concentration, by irradiating the waste water with ultraviolet rays in excessive hydrogen peroxide whose amount is enough to decompose an organic substance by oxidation, and then by making it into contact with active carbon.
CONSTITUTION: Fluoric acid, inorganic salt, methanol, halogen hydrocarbon, etc., are mixed. Water used to flushing electronic parts has fluoric acid removed in an ion exchange method, etc., without increasing salt concentration substantially and its pH is adjusted to 3W8. An enough amount of excessive hydrogen peroxide to decompose the organic substance in the water, namely, 2W3-fold equivalent weight one is added and the water is irradiated with ultraviolet rays to decompose the organic substance by oxidation. Then, it is made into contact with active carbon to decompose the excessive hydrogen peroxide.
