  • 摘要: 采用电渗析器处理过滤的褐藻酸钠废水，褐藻酸钠废水初始水质如下：Ca2+（56 mg/L）、Cl-（1 808 mg/L）、电导率（7.24 mS/cm）。处理目标值如下：Ca2+（60 mg/L）、Cl-（300 mg/L）、电导率（2.50 mS/cm）。运用Design-Expert分析软件，采用Box-Behnken的中心组合设计方法，研究了流量、电压及淡水浓水体积比及其交互作用对直流电耗的影响。建立了电渗析处理褐藻酸钠废水的二次多项数学模型，并以电渗析的直流电耗为响应值做响应面，确定电渗析处理褐藻酸钠废水的最佳工艺条件为：流量200 L/h、电压40 V、淡水浓水体积比1：1。在此条件下电渗析的直流电耗最小为0.45 kWh/kg，电渗析器处理后的水质如下：Ca2+（56 mg/L）、Cl-（259 mg/L）、电导率（2.00 mS/cm），达到处理目标。
    Abstract: The filtered sodium alginate wastewater was treated by electrodialysis. The initial water qualities of sodium alginate wastewater are as follws: Ca2+(568 mg/L), Cl-(1 808 mg/L), conductivity(7.24 mS/cm); the target value: Ca2+(60 mg/L), Cl-(300 mg/L), conductivity(2.50 mS/cm). With Design-Expert software, the effects of flow, voltages and volumes ratios of dilute to concentrated wastewater as well as their interactions on direct-current(DC) consumption were studied by the Box-Behnken central composite design method. The quadratic polynomial mathematical model of the electrodialytic sodium alginate wastewater treatment was developed by Design-Expert software, and DC consumption was designed as response value. The parameters of response surface were optimized, and the optimum process conditions were as follows: flow of 200 L/h, voltage of 40 V, volumes ratios of dilute to concentrate of 1:1. Under the optimum conditions, the actual DC consumption was 0.45 kWh/kg, and the water qualities of sodium alginate wastewater were: Ca2+(56 mg/L), Cl-(259 mg/L), conductivity(2.00 mS/cm), which met the target of wastewater treatment.
