摘要
研究城市污水氮、磷处理工艺．研究表明，用活性污泥一藻共生的间歇法有效地去除模拟城市污水中的氮、磷．采用人工富营养形式利用氮，可以取消惯常缺氧反硝化过程．活性污泥在系统中提供良好的絮凝作用，无需专门除藻措施．混合条件不影响藻类生长．藻类死亡后形成的有机物能被活性污泥利用。
The Paper discusses the new technology of denitrifcation and phosphorus re-moval for municipal wastewater.It is presented that nitrogen and phosphorus in wastewater could be efficiently removed with symbiotic system of activated sludge-aglge by SBR.Anoxic denitrification processes could be omitted with artificial eutrophion and assimita-tion of nitrogen by aglae.By the bio-floccalation, activated sludge could substitute for aglae collection opera-tion,as used in oxidation pond conventionally. Agitation does not affect on the growth of aglae and converted organics,remains of aglae ,could be metabolised by bacterias in activated sludge.
