在实验室中自行合成磺化聚砜（ＳＰＳ），刮制成板式、管式超滤膜，进行处理含油污水的实验室小试及现场中试，并与聚砜（ＰＳ）超滤膜对比．自制ＳＰＳ超滤膜的透水速度随离子交换当量（ＩＥＣ）的增大而增大．选用ＩＥＣ值在０．１～０．２ｍｏｌ／ｇ的ＳＰＳ作为膜材料．在处理含石油类（１０～８０ｍｇ／Ｌ）的含油污水时，与ＰＳ膜对比，ＳＰＳ膜的通量下降率较小，能维持较高的水通量；二者的截留率都在９０％以上，透过液中含油量、悬浮物、细菌等都基本达到国家排放标准及油田回注水水质标准．因此，从膜性能角度考虑，以ＳＰＳ膜代替ＰＳ膜在一定条件下能维持较高通量，有一定的优越性．
Sulfonated polysulfone (SPS) was synthesized in the laboratory and scraped into a plate-type and tubular-type ultrafiltration membrane. The laboratory-scale pilot and field pilot treatment of oil-contaminated water was carried out and compared with the polysulfone (PS) . The permeation rate of self-made SPS ultrafiltration membrane increases with the increase of ion exchange equivalent (IEC). Select the IEC value of 0.1 ~ 0.2mol / g of SPS as a membrane material. When treated with oily wastewater containing petroleum (10 ~ 80mg / L), compared with the PS membrane, the decrease rate of the membrane flux of the SPS membrane is small, and the water flux can be maintained; the rejection rates of the two membranes are both 90% Above, through the liquid oil content, suspended solids, bacteria, etc. have basically reached the national emission standards and oilfield injection water quality standards. Therefore, from the membrane performance point of view, to replace the PS membrane with SPS membrane under certain conditions to maintain a higher throughput, there are some advantages.
