Abstract
With the process of industrialization, many production fields produce high-salt organic wastewater. In this work, we have employed an electrodialysis (ED)-resin-bipolar membrane electrodialysis (BMED) mixed process to address sodium acrylate wastewater, achieving resource recovery. The influences of the initial volume ratio and applied voltage were investigated. In the ED-resin, the separation of organic compounds and pigments such as sodium acrylate and phenol was realized. The desalting rate could reach 93.1%, the energy consumption is 0.6 kWh/kg C3H3O2Na, and the chroma removal rate can reach 99%. In the subsequent BMED phase, we attain notable acrylic acid and base concentrations, reaching levels of 1.59 mol/L and 3.12 mol/L, with a current efficiency of 58.14% and an energy consumption of 3.28 kWh/kg NaOH. In addition, economic and environmental evaluations verify the feasibility of this process, which is indicative of its prospect of industrial application.
