阐述了煤矸石制备聚合硅酸铝铁(PFASS)絮凝剂的原理,并以化学需氧量(COD)、水中固体悬浮物含量(SS)及色度为指标,评价了其对长庆油田采油污水处理的最佳投入量、最佳作用时闻等.研究结果表明,和其他类型的絮凝剂相比,采用该工艺生产的PFASS产品对油田污水的处理效果较好,COD的去除率为79.36%.SS的去除率为84.2%.色度去除率为88.6%.利用煤矸石制备的絮凝剂处理油田污水是一种变废为宝、以废治废的好方法.
闡述瞭煤矸石製備聚閤硅痠鋁鐵(PFASS)絮凝劑的原理,併以化學需氧量(COD)、水中固體懸浮物含量(SS)及色度為指標,評價瞭其對長慶油田採油汙水處理的最佳投入量、最佳作用時聞等.研究結果錶明,和其他類型的絮凝劑相比,採用該工藝生產的PFASS產品對油田汙水的處理效果較好,COD的去除率為79.36%.SS的去除率為84.2%.色度去除率為88.6%.利用煤矸石製備的絮凝劑處理油田汙水是一種變廢為寶、以廢治廢的好方法.

The principle of preparation of PFASS by using gangue was introduced. By examining indexes such as COD, SS and chrominance, the best dosage and operating time were evaluated for waste water from Changqing Oilfield. It shows from the experiment that: Compared with other flocculating agents, PFASS produced from the technology mentioned has a good effect on the waste water in the oilfield ,with which COD removal ratio is 79.36%, SS removal ratio is 84.2% .and chrominance removal ratio is 84.2%; using PFASS produced from gangue to treat field water is a good way to prevent against waste.
