摘要
以粉煤灰为主要原料,掺加少量黏土,经混合、成球、高温焙烧制成粉煤灰颗粒吸附剂,研究该吸附剂对含磷废水的处理能力,并采用单因素试验来确定影响因素。结果表明,吸附剂的吸附特性受吸附时间、吸附剂投加量、搅拌速度、pH值、温度等因素影响,且粉煤灰颗粒吸附剂符合Langmuir吸附等温吸附方式。
Fly ash was adopted as raw material mixed with clay by sintering to make fly ash granule adsorbent. The adsorption ability of fly ash granule adsorbent on removal of phosphorus from wastewater and the influenced factors were discussed using a method of one-factor experiment. The result showed that the adsorption of fly ash granule adsorbent was depended on adsorption time, fly ash granule adsorbent dosage, agitate density, pit value and temperature, etc. The adsorption isotherm of fly ash granule adsorbent could be well fitted the Langmuir equation.
