摘　　要：用耐盐活性剂DM-5522和耐盐破乳剂ROD-1609分离提纯造纸制浆废液中的木质素，并在无盐条件下通过磺化，络合，共聚等反应合成磺化木质素，铁铬木质素磺酸盐（FCLS），磺化木质素磺甲基化酚醛树脂共聚物（SLSP）．实验表明，利用该方法处理造纸制浆废液，分离出的无机盐不仅可以回收使用，而且木质素改性产品在油田钻井和开采方面的应用性能优于其他木质素工业品，达到了造纸制浆废液无害化改性利用的目的，具有极大的经济效益和环境效益．In the acidic condition, ]ignin can be separated out from paper- making pulp effluent, but because of the existence of the amount of salt, the surface tension is high so that separation of lignin is very difficult even in this condition. In the acidic condition, the surface tension of Paper - making pulp effluent drops to below 35 mN · m-1 by surfaetant of salt - tolerant DM - 5522. Under the action of demulsifier of salt - tolerant ROD- 1609, lignin conglomerates and flocculates. By eentrifugation, lignin with high purity can be got and desalination rate reaches up to 98% , while the inorganic salt solution can be recycled by paper mill, it doesn~ bring secondary pollution to the environment. Lignin purified is synthesized into Sulphonated lignin, Iron chromium lignosulphonate salt （FCLS） and sulfited lignin sulfomethylated phenolaldehyde resin （SLSP） through the sulphonated reaction, complexation reaction and copolymerisation in the condition of salt free. Experimental results indicate that the performance of these lignin＇s modified products is superior to other industrial lignin products in oilfield drilling and exploration. It reaches the purpose of the harmless modification of paper - making pulp effluent and has great economic benefits and environmental benefits.
