| 摘 要： | 针对低有机物高氨氮浓度的生活污水，经UASB处理后的厌氧废水，氮含量较高，磷基本未除去，处理出水效果欠佳的情况，提出磷酸铵铗沉淀法脱除生活污水中的磷以及部分氨氮。初步确定了影响磷酸铵镁沉淀反应因素为pH值，Mg^2＋：PO4^3-：NH4^＋，反应时间t。最优反应条件为：pH=8．5，Mg^2＋：PO4^3-：NH4^＋=1．2：1：1，反应时间t=1min。磷的去除率可高达94．0％，氨氮的去除率达71．5％，为低浓度的生活污水的后续生物处理创造了良好的条件。

| Abstract: | Aimed at the low organism and high ammonia nitrogen of vital sewage,after removed by the UASB,however there were high content of nitrogen and mostly phosphorus,the disposal effect of quality was not nice.By means of Magnesium Ammonium Phosphate,partial nitrogen and almost phosphorus from wastewater can be removed.The factors about the impact of magnesium ammonium phosphate precipitation response is pH,Mg2+:PO3-4:NH+4,the time of response.The best of response condition is: pH=8.5,Mg2+:PO3-4:NH+4=1.2:1:1,t=1 ... |
