报道凤眼莲（ＥｉｃｈｈｏｒｎｉａｃｒａｓｓｉｐｅｓＳｏｌｍｓ）在炼油废水中的生长状况，并对以ＣＯＤ为综合指标的污染物浓度之间的关系作了定量研究。结果表明：用凤眼莲生态工程处理炼油废水实施运行最佳控制条件为６５ｍｇ／Ｌ＜［ＣＯＤ］＜１３１ｍｇ／Ｌ，临界有效点为［ＣＯＤ］＝２６２．６ｍｇ／Ｌ。
The growth status of Eichhornia sacrassipes in oil refinery wastewater was reported and the relationship between the concentration of pollutants with COD as a comprehensive index was quantitatively studied. The results showed that the optimum operating conditions for the treatment of refinery wastewater with Eichhornia crassipes were 65mg / L [[COD] <131mg / L, and the critical effective point was [COD] = 262.6mg / L.
