摘　　要：采用由陶瓷超滤膜及反渗透膜组成的膜分离中试系统对APMP废液进行了预浓缩试验,研究发现：在20nm膜孔径、2bar跨膜压力、80℃和体积浓缩因子为8的条件下,膜分离中试系统废液通量达到89.1L/（m2·h·bar）,最终浓缩液固形物可达58.38g/L。中试线浓缩能耗约为5kwh/t废液,二级反渗透的通量稳定在38L/（m2·h·bar）以上,出水无色透明,电导率在10~30μS/cm范围内,CODCr为380~550mg/L,经气提后CODCr可进一步降低到200 mg/L以下,可满足APMP制浆过程用水水质要求。APMP combined effluent was treated by pilot membrane separation system which consists of ceramic ultrafiltration membrane and reverse osmosis,the result show that at the condition of 20 nm bore size,2bar transmembrane pressure,80℃ and volume concentration factor of 8,the flux reaches 89. 1L /（ m2·h·bar）,total solid consistency increases from 22. 57 g / L to 58. 38 g / L. while the energy consumption of which was 5kwh / t,the final reverse osmosis permeate flux remains above 38 L /（ m2·h·bar）. The conductivity and CODCrof permeate are 10~ 30μS / cm and 380 ~ 550 mg / L,respectively,CODCrof the permeate can be further reduced to less than 200 mg / L by steam lift,the water quality can meet the demands of APMP line.
