改性磁铁矿工艺对含磷废水的处理效果
Effect of Phosphorous Containing Wastewater Treatment by Modified Magnetite Process
摘要
Abstract
Three modified magnetites were prepared to adsorb phosphorous wastewater, containing modified base, coated polyacrylamide modified and clad oil sodium modified,respectively. The adsorption of phosphorus in aqueous by modified magnetite under different conditions of adding dosage,initial concentration of phosphorus and initial pH value was studied. And the isothermal adsorption experiments were conducted. The results showed that the removal rate of phosphorus was the best after coated a polyacrylamide,up to 80%. And Langmuir and Freundlich isotherm equation could well describe the adsorption isotherm characteristic of modified polyacrylamide coated magnetite and fit its maximum adsorption capacity of up to 58 mg/kg. Phosphorus removal rate of low concentration phosphorus solution was greater than a high concentration of phosphorus solution,and the removal rate of phosphorus was the highest at a pH value of about 3.关键词
