摘　　要：随着环保标准的日益严格,脱氮除磷成为污水处理的必然发展趋势,因此开发低成本、高效率、运行管理简单的脱氮除磷工艺具有重要意义。对化学强化一级处理联合流动床生物反应器(CEPT—MBBR)的脱氮除磷效果进行了中试研究。结果表明,CEPT—MBBR工艺脱氮除磷效果可靠,出水水质好,它不仅适用于有脱氮除磷要求的新建污水处理厂,也适用于对现有污水处理厂的升级改造,应用前景广阔。With more strict standards of wastewater treatment being set, the removal of nutrients will be a basic requirement for WWTPs. It is very important to develop nutrients removal wastewater treatment technologies with low costs, high efficiencies and simple operation management. The effects of nutrients removal in combined CEPT - MBBR process in a pilot-scale experiment were studied. The experimental results indicate that the combined CEPT - MBBR process has reliable effects on nutrients removal, with good effluent. It is suitable for the constructions of the new WWTPs that have the requirement of nutrients removal and the upgrading of existing WWTPs.
