TREATMENT OF PHOSPHORIC ACID IONS-CONTAINING WASTE WATER AND TREATMENT DEVICE THEREFOR

Title:

TREATMENT OF PHOSPHORIC ACID IONS-CONTAINING WASTE WATER AND TREATMENT DEVICE THEREFOR

Document Type and Number:

Japanese Patent JPH10225690

Kind Code:

A

Abstract:

To provide a treatment method of phosphoric acid ions-containing waste water to enhance removal efficiency of the phosphoric acid ions.

This waste water treatment method is constituted to electrochemically elute iron ions and /or aluminum ions into the phosphoric acid ions- containing discharge water by using electrode 4, 5 containing iron ions and/or aluminum ions and flocculate and settle the phosphoric acid ions in a form of water-insoluble salt with iron and/or aluminum, and generation sources of Ca ions and/or Mg ions are allowed to be present on in the electrodes 4, 5.
