| 摘 要： | 论文探讨A型沸石对废水中磷的吸附性能,影响A型沸石对磷吸附的主要因素有吸附温度、灰水比、吸附时间和pH值。通过单因素和正交试验确定在水样体积30mL,A型沸石投加量3g,吸附时间为40~50min,吸附温度25oC,pH值4~5范围内,初始磷浓度小于20 mg/L,A型沸石对磷都有很好的吸附效果。TP去除率达99%以上,对磷的吸附容量约为0.44mg/g,适用于工业废水处理和生活污水的深度除磷。

| Abstract: | This paper is focused on the adsorption of phosphorus from wastewater by A-zeolite. It is found that the main factors affecting the phosphorus removal efficiency by A-zeolite are adsorption temperature, A-zeolite addition dosage, pH and the adsorption time. High removal efficiency can be obtained with the conditions by single element and orthogonal experiment, sewage volume 30mL, A-zeolite addition dosage 3g, adsorption time 40-50min, adsorption temperature 25 ℃, pH 4-6 and the initial phosphorus content of less than 20mg/L. The removal efficiency of phosphorus is more than 98% and the adsorption capacity of A-zeolite is 0.44mg/g. It is applicable to the advance treatment of phosphorus in industrial wastewater and domestic sewage. |
