摘要
采用鸟粪石沉淀法去除臭氧氧化污泥溶解液中氮磷的效能,分析了搅拌时间、镁磷比、pH对形成鸟粪石的影响。结果表明,最佳控制条件pH为10.0、镁磷量比为1.8:1、搅拌时间为10 min,此时TP和氨氮的去除率分别为88.5%和18.8%。鸟粪石法既可以去除破解液中的氮磷,又可得到鸟粪石,实现磷的循环利用。
Nitrogen and phosphorus in the sludge were removed by struvite dissolved.The result showed that the removal rates of total phosphorus was 88.5% and the removal rates of ammonia nitrogen was 18.8%,respectively,under the optimal conditions which is pH 10.0,n（Mg）：n（P）=1.8：1.0,stirs 10 min.Struvite method not only remove nitrogen and phosphorus from fluid,but also achieve the recycling of phosphorus.
