ACIDIC WATER TREATMENT CONDITION DESIGN METHOD AND ACIDIC WATER TREATMENT METHOD

摘要

To provide an acidic water treatment condition design method that can rationally design the conditions for charging a neutralizing agent to reduce both the amount of the neutralizing agent and the volume of the neutralized residue according to the properties of the acidic water to be treated, and an acidic water treatment method.SOLUTION: The acidic water treatment condition design method according to the present invention includes charging a neutralizing agent containing a calcium compound and a magnesium compound and pulverized into acidic water to be treated for neutralizing, and obtaining in advance the primary equation (a), which is a relational expression between the volume cumulative particle size at 90% by volume of the neutralizing agent, and the amount of the charged neutralizing agent per 1 liter of the acidic water, and the primary equation (b), which is a relational expression between the volume cumulative particle size at 90% by volume of the neutralizing agent, and the volume of the neutralized residue per 1 liter of the acidic water; and based on these relational expressions, designing the volume cumulative particle size at 90% by volume of the neutralizing agent and the charging amount. Moreover, the treatment method of the acidic water designed by the design method is also provided.SELECTED DRAWING: Figure 1
