摘　　要：采用高倍膜浓缩技术对燃煤电厂脱硫废水零排放系统反渗透浓水进行深度浓缩处理中试试验研究。通过168 h连续运行测试,验证了高倍膜浓缩技术在6~7 MPa的运行压力下将浓盐水浓缩至100 g/L以上的可行性。现场连续运行测试结果表明,高倍膜浓缩工艺具有浓缩极限高、操作压力低、系统运行稳定的特点,可用于废水零排放反渗透浓水的减量化处理。A pilot study on the advanced membrane concentration process(AMCP)is conducted for the treatment of reverse osmosis concentrate brine in a zero discharge system of desulfurization wastewater from coal-fired power plants.Through 168 hours of continuous operation,the feasibility of concentrating brine salinity to over 100 g·L-1 using AMCP at an operating pressure of 6-7 MPa is verified.It is revealed by the spot continuous pilot-scale test that AMCP has the features such as high concentration limit,low operating pressure,and stable system operation,and can be used for the reduction treatment of reverse osmosis concentrated brine.
