鸟粪石 Fenton氧化处理老龄垃圾渗滤液的试验
Experiment of Struvite Precipitation-Fenton Processes for Mature Landfill Leachate Treatment
摘要
Abstract
The optimum conditions of combination of struvite precipitation and Fenton process to treat the landfill leachate were explored in this paper. The results show that the combined treatment process takes advantages of both methods. When the initial pH is 9. 5,molecular ratio of Mg2+∶PO3-4 ∶NH4+ is 1. 3∶1. 2∶1 and reaction time is 30 min by struvite precipitation;and when the initial pH is 3. 3,concentration of H2 O2 is 0. 03 mol/L,molecular ratio of H2 O2∶Fe2+ is 4∶1 and reaction time is 2 h by Fenton process,COD removal rate is 86. 68% and ammonia nitrogen removal rate is 92. 27%,which are apparently superior to the result of struvite precipitation (COD removal rate is about 85%,ammonia nitrogen removal rate is 15%~20%),the result of Fenton process (COD removal rate is about 55%,ammonia nitrogen removal rate is almost zero),as well as the result of the combination of two methods in reversed order (COD removal rate is around 40%,ammonia nitrogen removal rate is around 20%).关键词
