摘　　要：对腐殖土活性污泥工艺进行了阐述,介绍了该技术在国内外的应用情况。对比探讨腐殖土及其微生物对于改善污泥性能及提高污水处理效率的情况,结果表明:经过腐殖土反应器调理后,活性污泥的脱水性和沉降性得到显著提高,污泥减量效果明显;经腐殖土调理后活性污泥虽然没有显著提高对COD的去除效率,但对COD的处理时间明显减少,对氮、磷的去除率得到明显的提高。The introduction of humus activated sludge process and its application at home and abroad were expounded. The humus soil and its microorganisms have the capability of improving the sludge performance and sewage treatment efficiency. The comparison results indicated that the dehydration property and settle ability of activated sludge were increased significantly after opsonization by humus soil reactor, and the sludge achieved reductions. Although the COD removal efficiency was not increased, the COD removal processing time significantlyreduced, the nitrogen and phosphorus pollution removal efficiencies were significantly increased.
