摘要

对粉煤灰、矾土、活性炭、蛭石和火烧石5种基质的元素含量和表面化学性状进行了研究

并比较了这5种基质对P和NH4+-N的吸附性能。结果表明:粉煤灰呈碱性

具有较高的Fe、Ca含量

胶体氧化铁和水溶性Ca含量也最高

矾土呈酸性

Al含量和游离氧化铝含量最高

蛭石和火烧石呈中性

其中蛭石含有21.6%的Mg

活性炭比表面积最大。Langmuir等温吸附曲线方程能够对上述基质的P、NH4+-N吸附过程进行了很好的拟合

其中P理论饱和吸附量由大到小依次为粉煤灰>矾土>火烧石>活性炭>蛭石

NH4+-N饱和吸附量由大到小依次为蛭石>粉煤灰>火烧石>活性炭>矾土。双元素(P和NH4+-N)溶液下

基质对P或NH4+-N的理论饱和吸附量较单元素(P或NH4+-N)溶液下要低。在5种基质中

粉煤灰对P、NH4+-N的综合吸附能力较强

推荐其作为水体N、P污染修复的首选基质。

Abstract

Both phosphorus(P) and ammonium(NH+4-N) adsorption capacities of fly ash

alumina

activated carbon

burnt stone and vermiculite with physical and chemical characteristics were examined for the potential use as substrate in removing P and N in polluted water.Results showed that: Among the 5 substrates

fly ash was alkaline with the highest Fe

Ca and active Fe

Ca contents

while alumina was acid with highest Al and active Al contents.There was 21.6% of Mg found in vermiculite.Activated carbon had the largest spec...
