摘要
在磷灰石、钙、氟的共同作用下,可以使水体中的磷浓度显著降低。以此为基础,在含磷水溶液中调节反应物(磷灰石、钙、氟)浓度,通过监测水溶液中磷浓度的变化,探讨了加入物浓度对降磷效果的影响,初步确定了适合的反应物加入量,并试验了其他因素如震荡作用和催化剂对降磷的影响。最后探讨了固化沉淀的反应速率。
It is proved that adding some reactants, such as F, Ca and phosphorite, to solution containing phosphorus can markedly reduce the phosphorus contents in the solutions. Based on this fact, the dosage of the reactants have been optimized for phosphorus reduction. The other factors affecting the phosporus reduction, such as shaking, adding of the catalysts and etc. are discussed. And the reaction rate for the precipitate solidification is also discussed.
