摘要
对比研究了厌氧—好氧交替条件下(AAA工艺)活性污泥对三组磷浓度不同的模拟生活废水的除磷效果。试验结果表明,活性污泥对磷浓度为6mg/L左右的废水处理效果最好,磷去除率可达97%;对磷浓度为16.66mg/L和2mg/L左右废水的磷去除率则分别为78.4%和75.3%;并探讨了活性污泥法的除磷机理。
This paper compares the phosphorus removal characteristics of activated sludge in ahernation of aerobic/anaerobic（ AAA process）using synthetic domestic wastewater of three different phosphorus concentrations as the feed. It is shown that the phosphorus removal efficiency of activated sludge to wastewater about 6mg/L is the best,which reaches 97% ;as to the wastewater of 16.66mg/L, the phosphorus removal efficiencies reach 78. 4% and 75. 3% respectively, Furthermore, it discusses the phophorus removal mechanism of acivated sludge method.
