摘　　要：采用改性粉煤灰对一级处理后的生活污水进行吸附实验,研究了改性粉煤灰去除污水的效果及其影响因素。结果表明,60min后改性粉煤灰吸附过程基本完成,其pH值范围与实际污水相符,改性粉煤灰最佳投加质量浓度为40g/L,对较低COD浓度的生活污水去除效果较好,其出水的CODCr、总磷和氨氮均达到国家城镇污水处理厂污染物排放标准(GB18918-2002)二级排放标准。Adsorption experiments were conducted to investigate on the efficiencies and factors of contamination removal from primary treated domestic sewage by modified fly ash. The results showed that process for removal of COD could be basicly finished in 60 min, the range of pH value was in accord with that of the practical sewage, and the optimum amount of the MCFA added was 40g/L, and the MCFA had a better adsorption in less COD concentration of sewage. The COD, total phosphorus and ammonium concentrations of effluent reached the second grade discharge standard of GB 18918-2002.
