摘要
磷酸铵镁(MAP)技术是一种有效去除废水中高浓度氨氮和高浓度磷酸盐的技术。本文介绍了MAP技术的应用研究概况。评述和探讨了MAP技术的影响因素:pH值、物质摩尔配比,反应时间、反应温度、物质浓度、搅拌速度、陈化时间、沉淀剂加入方式。指出了MAP技术面临的问题及解决思路。
The technology of magnesium ammonium phosphate(MAP) is one of effective removal of high strength ammonia nitrogen and phosphate in wastewater. Integrating research conditions, the paper reviews the outline of applied researches on MAP technology, enquires into the affecting factors of MAP technology, such as, pH value, material mole ratio, reaction time, reaction temperature, material concentration, stirring speed, ageing time, way of precipitation agent dosing, and points out the problems MAP faces and the train of solving these problems.
