摘　　要：以炉渣作为吸附剂 ,用静态吸附实验方法研究了炉渣对模拟含磷废水脱磷的一般规律 ,结果表明 ,炉渣是一种有效的吸附剂 ,对废水中的磷有较强的吸附去除性能。影响炉渣除磷的主要因素有吸附时间、炉渣用量、pH值和原水含磷浓度。在含磷浓度 2～ 13mg/L、炉渣用量 5 g/L、中性、吸附时间为 2h的实验条件下 ,磷的去除率可高达99%以上。Based on a series of experiments, this paper studied the capacity of slag for removal of phosphorus from model wastewater.The results show that slag is effective in adsorbing phosphorus.The factors affecting the removal of phosphorus are the initial phosphorus concentration,pH value,adsorption equilibrium time and the amount of slag.When the concentration of phosphorus is 2～13 mg/L,the amount of slag used is 5 g/L,the pH value is neutral, and the adsorption time is 2h,the removal rate of phosphorus can be higher than 99%.
