Purification treatment method and purification treatment agent |
| abstract |
It is an object of the present invention to provide a purification treatment method and purification treatment agent capable of effectively removing fluorine from polluted water or contaminated soil containing fluorine in a simple sequence and simultaneously removing a predetermined heavy metal. The purification treatment method of the present invention is a purification treatment method for removing fluorine from contaminated water or contaminated soil, comprising the steps of adding a pH adjuster to the effluent eluted from the contaminated water or contaminated soil so that the pH is 6.5 or less, , Or a combination thereof, with the contaminated water or the contaminated soil. In the step of adding the pH adjuster, the pH of the eluate eluted from the contaminated water or the contaminated soil may be adjusted to 3 or more and 5 or less. The purification treatment agent of the present invention is characterized by being used in contact with the effluent eluted from the contaminated water or the contaminated water containing an alloy steel powder containing sulfur, phosphorus, or a combination thereof adjusted to a pH of not more than 6.5 . |
