Based on practice and analysis, it is put forward that the effective decrease of residual P2O5 in phosphorus furnace slag depends on the control of acidity coefficient from the slagging and reduction of P2O5. Also a relative formula for the calculation of acidity coefficient is presented.

结合生产及理论分析，指出在控制磷炉渣酸度系数中，必须兼顾满足造渣和还原反应两方面的要求，才能有效降低磷炉渣中残留的P2O5量，并且推导出相应的计算式，以消除酸度系数控制的局限。

Key words: phosphorus furnace slag; acidity coefficient; slagging; calculation; control

磷炉渣；酸度系数；造渣；计算；控制

This paper detaily discussed the technical principle of activated-sludge process and the reaction mechanism of biological nitrogen and phosphorus removal in anaerobic period,anoxic period and aerobic period.

本文系统详细的论述了活性污泥法的工艺原理以及生物除磷脱氮工艺的厌氧、缺氧、好氧反应阶段的反应机理。

The effects of magnetic seed, aluminum sulphate and pH value on phosphorus adsorption, precipitation and coagulation were surveyed. The results made it clear that Al ion as precipitant and coagulant was the main effect factor on P removal; as adsorbent magnetic seed had little effect on P removal, but made the phosphate precipitate sink faster; pH value had effect on both precipitation and adsorption.

研究了磁种、硫酸铝、pH值等对磷的吸附、沉淀、凝聚的影响，结果表明：铝离子的沉淀作用是除磷的主要原因；磁种的吸附作用对除磷的贡献较小，但使磷酸盐沉淀物的沉降性能大大提高；pH值既影响沉淀作用，也影响吸附作用。
