Study on the biological treatment strengthened by powdered activated carbon and coagulants

Abstract

中国日益严峻的环境形势和越来越严格的污水排放标准,使得众多的污水处理厂迫切需要一种符合国情,经济又高效的生物强化技术来提高传统活性污泥法去除有机物、N和P的效率,从总量上控制并减少这三类污染物质进入水体的数量。 本文以厦大学生宿舍区下水道生活污水为处理对象,采用按A/O方式运行的SBR反应器作为实验平台,研究投加粉末活性炭和混凝剂是否会强化活性污泥对有机物、N和P的去除能力,初步得到了一些结论: (1)全过程一次性投加粉末活性炭可以强化活性污泥对有机物的去除效果,而且与投加量有关,其中一次性投加2.4g粉末活性炭后(按反应器体积计:400mg/L)的COD去除率相对于对照组提高的百分比平均...China's increasingly severe situation of the environment and increasingly stringent wastewater discharge standards, making many of the wastewater treatment plants with an urgent need for a kind of bioaugmentation technology which is according with national conditions, economic and efficient to improve the removal rate of organic matter、N and P by the traditional activated sludge process, control a...学位:工学硕士院系专业:海洋与环境学院环境科学与工程系_环境工程学号:2122005130224
