对除盐系统酸、碱再生废液的中和处理的计算公式进行了推导，用理论分析和数理推导的方法，证明了除盐系统酸、碱再生废液混合后仍显酸性，并以此提出了再生废液中和处理新工艺，设计了新颖实用、符合环保要求的处理方案。

The mathematical calculation formula for a neutralization treatment of acid - basic regenerated waste liquids in desalting treatment is discussed. The acidity of a acid - basic mixed liquid in desalting system is demonstrated by theoretical analysis and mathematical calculations. A new technology of regenerated waste liquid treatments is put forward. The practical-environmental protection scheme is designed.
