摘要:
真空膜蒸馏（VMD）处理反渗透（RO）浓水过程中膜污染不可避免。对此，优化了膜运行条件，探究了无机、有机及有机-无机复合污染物对VMD效能的影响规律。结果表明，经优化后，VMD系统的进料温度为70 ℃、真空压力为0.09 MPa、进料流量为600 L/h。以RO浓水为进料液时，膜通量相对初始值的下降率随着进料温度和真空压力的升高而增加，随着进料流量的增大而降低；向RO浓水中加入海藻酸钠（SA）时，膜通量相对初始值下降了67.87%，主要是因为形成了有机-无机复合污染层。
Abstract:
During the vacuum membrane distillation (VMD) treatment of concentrated water from reverse osmosis (RO), membrane fouling is inevitable. To address this, optimization of membrane operating conditions was conducted, and the impact of inorganic, organic, and organic-inorganic composite pollutants on the efficiency of VMD membranes was investigated. The results indicated that the optimal operating conditions for the VMD system were a feed temperature of 70 ℃, a vacuum pressure of 0.09 MPa, and a feed flow rate of 600 L/h. When RO concentrated water was used as the feed liquid, the rate of decline in membrane flux relative to the initial value increased with increasing feed temperature and vacuum pressure, and decreased with increasing feed flow rate. When sodium alginate (SA) was added to the RO concentrated water, the membrane flux relative to the initial value decreases by 67.87%, primarily due to the formation of an organic-inorganic composite fouling layer.
