阴床、阳床、混床

阴床即阴离子交换器，其中只装填阴树脂（强碱型、弱碱型），用来吸收氯离子等阴离子；阳床即阳离子交换器，其中只装填阳树脂（强酸型、弱酸型），交换吸收 Na+、Ca+等阳离子。 混床（高速混床）即混合离子交换器，其中装填阴阳两种树脂，用来去除水中剩余的阴阳离子。 阴阳离子再生罐用于饱和的阴阳离子复苏。 
The anion bed is an anion exchanger filled solely with anion resins (strongly basic or weakly basic) to absorb anions such as chloride ion, while the cation bed is a cation exchanger filled solely with cation resins (strongly acidic or weakly acidic) to exchange and absorb cations such as Na+ and Ca+. The mixed bed (high-speed mixed bed) is a mixed ion exchanger filled with both cation and anion resins to remove residual cations and anions in water. The anion and cation regeneration tank is used for the rejuvenation of saturated anions and cations.
