摘要
通过烧杯絮凝沉降观察和水样透光率测定,考察了8种阳离子和阴离子聚丙烯酰胺(PAM)、5种铝系无机絮凝剂、3种铁系无机絮凝剂及多种不同组成的二元、三元复配絮凝剂对含聚合物70mg/L的胜利孤东聚驱油藏产出污水的净化效果,得到了适合孤东采油厂的3个絮凝剂配方,即:300mg/L的AlCl3+0.5mg/L的AP(阴离子PAM);90mg/L的ZO(阳离子PAM)+210mg/L的AlCl3;120mg/L的FeCl3+180mg/L的AlCl3+0.55mg/L的AP(阴离子PAM),处理后水透光率≥95%。讨论了絮凝机理。
The water clearing capabilities of 8 grades of polyacrylamides （ PAM ）, cationic and anionic, 5 grades of inorganic Al coagulants,3 grades of inorganic Fe coagulants and lots of binary and tertiary combinational floccutants/coagulants of various composition were investigated for produced water from polymer flooded oil reservoir at Gudong and containing 70 mg polymer per liter through observating flocculation/precipitation in beaker tests and determining light transmittance of water samples at 430 nm. Three formulations of coagulants/flocculants in combination were shown to fit the polymer containing produced water of Gudong and composed of （ in mg/L） ： AlCl3 （300） ＋ anionic PAM AP （ 0. 5 ） ; cationic PAM ZO （ 90 ） ＋ AlCl3 （ 210 ） ; FeCl3 （ 120 ） ＋ AlCl3 （ 180 ） ＋ anionic PAM AP（0. 55 ） and,with these combinational clearing agents used, the treated produced water samples had light transmittance ≥95%. The mechanisms involved in water clearing were discussed.
