通过对高分子聚合物在水溶液中的有效粒径和Zeta电位的研究，探讨了无机盐对高分子聚合物絮凝性能的影响。研究结果表明：无机盐的存在对高分子聚合物的絮凝性能有不利影响，但随着无机盐浓度的增加，无机盐对高分子聚合物絮凝性能的不利影响有减弱趋势。就油田污水处理而言，低含盐情况下，应优先选用非离子聚合物作为絮凝剂；高含盐情况下，应优先选用阳离子聚合物作为絮凝剂。
通過對高分子聚閤物在水溶液中的有效粒徑和Zeta電位的研究，探討瞭無機鹽對高分子聚閤物絮凝性能的影響。研究結果錶明：無機鹽的存在對高分子聚閤物的絮凝性能有不利影響，但隨著無機鹽濃度的增加，無機鹽對高分子聚閤物絮凝性能的不利影響有減弱趨勢。就油田汙水處理而言，低含鹽情況下，應優先選用非離子聚閤物作為絮凝劑；高含鹽情況下，應優先選用暘離子聚閤物作為絮凝劑。

Through th e research on the effective diameter and Zeta potential of high molecular polymer in aqueous solution,the effects of inorganic salt on the flocculating performance of high molecular polymer are discussed. The result shows that the presence of inorganic salt has negative effect on the flocculating performance of high molecular polymer. With the increase of inorganic salt concentration,the negative effect on the flocculating performance of high molecular polymer has weakening tendency. As far as the oilfield wastewater treatment is concerned ,when the salt content is low,it is suggested that non-ionic polymer should be the preferred floccculant,while the salt content is high,the cationic polymer should be the preferred flocculant.
