| 摘 要： | 采取吸附试验的方法,选取沸石、无烟煤和粉煤灰作为人工湿地填料,对选用材料进行了吸附试验并对不同填料配比的去除氨氮效果进行了研究;同时研究了pH值、有机质和无机离子对最优配比去除氨氮效果的影响。结果表明:在相同的试验条件下,沸石、无烟煤和粉煤灰的质量比为1:2:1混合时,NH4+-N去除效果最好,达到95.8%;在pH值略偏酸性的条件下,最优配比对氨氮的去除效果最好,达到90%以上;有机质的种类和浓度也对最优配比去除氨氮有一定的影响,与空白相比,葡萄糖使得最优配比去除氨氮最大降低了57.4%,草酸浓度为0.2 mg/L时,氨氮去除率提高了12.79%;、SO42-、NO3-对最优配比去除氨氮的影响区别不大,与空白液相比氨氮的去除率下降35%左右。

| Abstract: | Zeolite,anthracite and fly ash were selected as constructed wetland filtering media,which were measured by method of adsorption test,and the effect of removing ammonia nitrogen with different packing ratio was studied.Influences of pH value,organic matter and inorganic ions on the effect of removing ammonia nitrogen with the optimal ration were also studied.Results showed that under the same experimental conditions,when the mass ratio of zeolite,anthracite and fly ash was 1:2:1,removal effect of NH4+-N was ... |
