摘　　要：采用雪硅钙石与氟化钙组合进行了处理低磷生活污水的实验研究,考察了反应时间、温度、进水pH值和振荡速度四种因素对该组合去除低磷效果的影响。结果表明:除磷的最佳反应时间、温度、进水pH值和振荡速度分别为4h、24.3℃、9和200r/min;总磷去除率均随四种因素的增加而增大,但增幅各不同。该组合能够稳定、高效、低耗的处理低磷污水,具有推广的价值。Combination of tobermorite and calcium fluoride was used to treat domestic wastewater with low phosphorus on a laboratory scale. Effect of four factors including reaction time, temperature, pH value of the influent and vibration rate on the treatment of low phosphorus wastewater was studied. Results showed that the optimum reaction time, temperature, pH value of the influent and vibration rate were 4h, 24.3℃, 9 and 200r/min respectively. Removal rate of total phosphorus increased with the increasing levels of the four factors, but the extent was different. The combination could treat low phosphorus wastewater steadily and cost effectively, and was worthy to be used widely.
