AI Technical Summary

Technical Problem

Existing methods for removing boron from desulfurization wastewater, such as adding hydrogen peroxide and solid-liquid separation, result in the decomposition of metal perborate salts over time, which do not meet regulatory discharge standards for land and sea areas.

Method used

A water treatment system and method that controls the concentration of hydrogen peroxide in the treated water to within a predetermined range, using calcium, strontium, or barium ions, to stabilize metal perborate salts and maintain boron concentrations below discharge limits, thereby preventing decomposition.

Benefits of technology

The system efficiently treats water to meet both land and sea discharge standards by stabilizing metal perborate salts, ensuring compliance with regulatory boron limits and preventing dissolution.

Abstract

To provide a water treatment system, a water treatment program, a water treatment method, and a method for suppressing the decomposition of metal perborate salts that can suppress the decomposition of boron-containing precipitates (metal perborate salts). [Solution] A water treatment system that removes boron contained in water to be treated by adding hydrogen peroxide to water containing boron to generate a solid metal perborate salt, and the water treatment system has a control means that receives information on the discharge location of the water to be treated and controls the concentration of hydrogen peroxide in the water to be treated to be kept within a predetermined range so that the concentration of boron in the water to be treated is lower than the upper limit of the set boron concentration set for each discharge location of the water to be treated.
