用水泥处理含磷废水的实验研究(5200字)
摘  要：随着水体富营养化的加剧，传统化的方法处理含磷废水的弊端日益明显，从而寻找一种新的方法处理含磷废水已经变得十分紧迫。本实验利用水泥的吸附特性，以磷溶液为吸附对象，探讨了吸附时间、吸附剂的用量、pH值对吸附效果的影响，实验表明：水泥对磷具有良好的吸附效果。在15分钟左右时可达到吸附平衡；吸附率随着水泥用量的增加而增大；在溶液pH为5左右时，吸附效果最好；实验在室温下就能达到很好的效果。

With the cement phosphorus wastewater treatment
Abstract: Along with the eutrophication intensifies, the traditional method of phosphorus wastewater treatment is more and more obvious, and the shortcomings of the search for a new method to deal with phosphorus wastewater has become urgent.Using cement with phosphorus adsorption characteristic, for adsorption object, solution discussed the dosage of adsorption time, absorbent adsorption, pH value, the effects of phosphorus experiments showed that: cement with good adsorption effect. In 15 minutes when can achieve adsorption balance; Adsorption rate with the nano dosage of cement increases; In the solution for five or so, the pH adsorption effect is the best; Experiment in the room temperature can achieve very good result.
Key words: Cement; Phosphorus; Adsorption；Anti-Mo-Sb spectrophotometry
