Title:
The disposal method of drainage containing a sulfuric acid ion and boron, and disposal equipment
Document Type and Number:
Japanese Patent JP6105500
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide, when treating wastewater containing sulfate ions and boron, a treatment method capable of increasing a rate of adsorption of boron on a laminar double hydroxide.SOLUTION: The treatment method comprises: a first step of passing raw water (wastewater) containing sulfate ions and boron through a reverse osmosis membrane (RO membrane) module of a reverse osmosis membrane device and thereby having sulfate ions removed from raw water (wastewater) containing sulfate ions and boron; and, thereafter, a second step of supplying permeated water (wastewater) having sulfate ions removed and containing boron to an LDH adsorption tower 2, thereby contacting the permeated water and laminar double hydroxide, and having boron in the permeated water adsorbed by the laminae double hydroxide and thereby removed.
