摘要

在实验室条件下，采用双层陶粒滤料曝气生物滤池工艺，以受氨氮污染的原生铁锰地下水作为研究对象，研究了模拟微污染地下水中铁、锰和氨氮的去除，分析了滤速变化对滤池中铁、锰和氨氮同步去除的影响及铁、锰和氨氮浓度沿滤层深度的变化。结果发现当滤速突然增加时，滤池经过2～3 d的培养后，出水铁、锰和氨氮均可达标；当滤速由0.74 m·h-1逐渐增加到3 m·h-1时，水中铁与氨氮的浓度一般都在滤层深度0.75 m处即可达标，但锰浓度达标的滤层深度却由0.75 m增加到1.60 m。

Abstract

Study on simultaneous biological removal of iron

manganese and ammonia in a simulated groundwater involving iron and manganese and pollutant ammonia-nitrogen was carried out in biological aerated filter with dual layer ceramic material.The influence of the flow rate on the removal of iron

manganese and ammonia and the change of their concentrations along the depth of the filter were measured.The results show that if flow rates increase suddenly only after 2—3 d culture for the filter

the concentrations of iron

manganese and ammonia at exit of the filter can be lower than that of the National Drinking Water Standard.It is found that when flow rates of the simulated contaminated groundwater increase from 0.74 m·h-1 to 3.0 m·h-1，the filter depth to meet the National Drinking Water Standard is only 0.75 m for concentrations of iron and ammonia in water

but it increases from 0.75 m to 1.60 m for the concentration of manganese.
