摘要 为了考察生物滤池对Fe2+、Mn2+和As(Ⅲ)的净化效果和沿滤层深度方向的去除规律,采用人工配制的含有As(Ⅲ)100~150μg/L,Fe2+0.5~1.5mg/L,Mn2+1~1.5mg/L的原水,通入已接种水厂成熟锰砂的生物滤池进行过滤试验。结果表明:生物滤池在120d运行过程中,原水中的As(Ⅲ)未影响滤柱对Fe2+、Mn2+的去除效果,滤池出水Fe2+<0.3mg/L、Mn2+<0.05mg/L,As(Ⅲ)<10μg/L,沿滤层深度Fe2+、Mn2+和As(Ⅲ)具有各自的去除规律。滤池滤料SEM检测和反冲洗泥样FRIT光谱分析结果表明滤池运行120d后,滤料表面及滤层中生长了大量微生物。
