The use of natural calcite seed crystal method for the simulation of phosphorus-containing wastewater treatment was investigated at different initial phosphorus concentration, reaction time, seed dosage, pH value and Ca/P molar ratio of phosphorus removal impact. The results showed that: Initial concentration of phosphorus had a greater impact on response time. The greater of the initial concentration of phosphorus, the shorter of reaction time of crystallization; the phosphorus removal was the best, when the seed dosage was 60 g/L, under certain conditions, with the increasing of initial concentration of phosphorus, pH value and Ca/P molar ratio of phosphorus was gradually weaken to the removal rate.%以天然方解石为晶种通过结晶法处理模拟含磷废水,考察了在不同的磷初始浓度条件下,反应时间、晶种投加量、pH值和Ca/P摩尔比对磷去除效果的影响.研究结果表明:磷初始浓度对反应时间影响较大,磷初始浓度愈大,结晶反应所需的时间愈短;晶种投加量为60 g/L时,磷去除效果最好;在一定条件下,随着磷初始浓度的增加,pH值和Ca/P摩尔比对磷去除率的影响逐渐减弱,所以应根据废水的具体磷初始浓度确定最适宜的pH值和Ca/P摩尔比.
