摘要
考察了柑橘皮对城市生活污水中磷的吸附影响,采用L16(45)正交试验进行了研究,同时对其热力学也进行了相关研究。结果表明,当柑橘皮的用量为2.0 g,反应温度为50℃,污水pH为3,反应时间为120 min时,柑橘皮对城市生活污水中磷的吸附率达到最大值,为98.79%,各因素影响的主次关系依次为柑橘皮的用量、污水pH、反应时间和反应温度;柑橘皮对污水中磷的吸附是自发且吸热的过程。
To study phosphorus of the urban domestic sewage adsorbed by the orange peel,L16 （45） experiment was conducted.The results showed that when the orange peel was 2.0g,reaction temperature was 50 ℃,pH of sewage was 3 and reaction time was 120 min,the maximum phosphorus of the urban domestic sewage adsorbed by the orange peel was 98.79%.The primary and secondary order that adsorptial rate was affected was the dose of the dosage peel,pH,reaction time and reaction temperature.The adsortion was a spontaneous and endothermic process.
