以某化工企业高盐废水为处理对象后，设计构建了电驱离子膜-分质结晶试验装置进行耦合技术废水处理资源化研究。结果表明，高含盐工业废水通过该工艺处理钙镁离子去除96%以上，产品水水质各项指标均能够满足试验设计要求，产水率在71%左右。电驱离子膜系统可将TDS全部浓缩到200 000 mg/L以上，均可达到进水的6~8倍，盐回收率≥89%。试验期间硫酸钠产品盐均满足产品盐品质要求，氯化钠产品盐合格率偏低。该耦合技术可以实现零排放及资源化试验目的。

An electric-driven ion membrane-segregation crystallization test device is designed and constructed to treat with high-salt wastewater in a certain chemical company to study the wastewater treatment recycling coupling technology.It is found from the results that the removal rate of calcium and magnesium ions from the high-salt wastewater by this coupling technology exceeds 96%,the quality indexes of the effluent water can meet the requirements of the test design,and the water yield is around 71%.The electric-driven ion membrane system can concentrate all TDS to more than 200 000 mg·L^-1,which is equivalent to 6-8 times that of the inflow water,and the salt recovery rate surpasses 89%.During the test,the produced sodium sulfate meets the product salt quality requirements,and the produced sodium chloride shows a lower qualified rate.This coupling technology can achieve the purpose of zero emission and recycling test.
