<p>The present invention relates to a method for recycling fluorine-containing waste water, which is generated in a process of etching glass and, more specifically, a method for recycling fluorine-containing waste water, which makes fluorine compounds among waste water heated at high temperatures react with a neutralizing agent and an aluminium component under proper pH and accordingly separates settlement with improved filtering due to big particle sizes and filtrates with low fluorine ion content wherein the method is allowed to efficiently treat the waste water by improving the filtering speed of the settlement; the settlement can be used as a basic material in industrial fields like an additive for cement and a glaze for ceramic; the filtrate has low fluorine ion contents and can be discharged without any process; and the neutralizing agent can be recycled, thereby significantly reducing creation of waste.</p> |
