【摘要】 针对钻井废水含油量高、化学需氧量高、悬浮物浓度及色度高的特点,综述了化学破乳法在钻井废水处理中的应用,详细阐述了化学法破乳的机理、絮凝剂的种类和性能。并提出絮凝剂逐渐由无机向有机和天然高分子化合物,由单一型向复合型转化的发展方向。更多还原

【Abstract】 Drilling wastewater is characteristic of high oil content , high COD, high suspended substance concentration and high colority. Application of chemical demulsification in drilling wastewater treatment was introduced. The mechanism of chemical demulsification and types and performance of the flocculants were introduced in detail. At last, the developing direction of flocculants was discussed from inorganic compound to organic compound and natural polymer compound, from single to compound.更多还原
