摘　　要：介绍了膜浓缩（MBC）零排放技术在长兴电厂脱硫废水深度处理项目中的应用情况。系统可将22mTh含盐水浓缩至1．5～2m^3／h，盐分浓缩至200g／L左右后进入蒸发结晶系统，最终生成结晶盐，经过浓缩处理后的清洁产水作为电厂锅炉补给水回用。运行结果表明，MBC零排放系统运行良好，有效地保证了电厂的稳定运行，带来良好的社会和经济效益。The application of membrane brine concentrator（MBC） zero liquid discharge technology to the advanced treatment project for desulfurization wastewater in Changxing Power Plant is introduced. 22 m^3/h of wastewater containing salt is concentrated to 1.5-2 m^3/h. After the salinity is concentrated to about 200 g/L,it goes to evaporative crystal system, and finally forms crystal salt. After the concentration treatment, the produced clean water can be reused as boiler make-up water for the power plant. The results show that the MBC zero discharge system runs well, and guarentees stable running of Changxing Power Plant, bringing good social and economic benefits.
