摘要
分析了城镇生活污水厂化学除磷技术现状,具体介绍了硫酸铝、硫酸亚铁和三氯化铁这三种无机化学药剂以及聚合氯化铝和聚合硫酸铁这两种有机化学药剂除磷的原理和效果,总结了我国化学除磷药剂目前存在的三点问题,最后讨论了化学除磷技术研究进展,不断向提高除磷效率和降低成本两个方向共同努力。
This paper analyzes the current status of chemical phosphorus removal technology in urban sewage treatment plants.Firstly,it introduces principles and effects of three inorganic chemical agents such as aluminum sulfate,ferrous sulfate and ferric chloride,and two organic chemical agents such as polyaluminum chloride and polyferric sulfate.Secondly,it summed up the current three problems of chemical phosphorus removal agents in China.Finally,it discussed the progress of chemical phosphorus removal technology research,and continue to work together to improve phosphorus removal efficiency and reduce costs.
