A/O+硅藻强化新工艺在中小型城镇污水处理中的应用总结

A/O+diatom New Technology to Strengthen Small and Medium-Sized Cities and Towns in the Application of Sewage Treatment in the Aggregate

采用A/O+硅藻精土强化工艺水处理技术对城市生活污水进行处理,工程运行结果表明,处理后的废水能够稳定达到《城镇污水处理厂污染物排放标准》(18918-2002)一级A标准。与其它生物处理工艺相比,有其独特的优点。该工艺已成功地应用于永城市污水处理中心,并获得2008年国家重点环境保护实用技术示范工程。而生物浮动床(MBBR工艺)+硅藻精土强化工艺是在此基础上的改进,并已成功地应用于污水处理。

The use of A/O＋diatomite process water treatment technology to strengthen the urban sewage processing,engineering,the results showed that the treated wastewater to achieve stability,＂Municipal Wastewater Treatment Plant Pollutant Emission Standards＂（18918-2002） A standard level.And other biological treatment process,has its own unique advantages.The process has been successfully applied to municipal sewage treatment center wing,and in 2008 the state＇s key environmental protection practical technology demonstration project.Biological floating bed（MBBR Technology） ＋ diatomite process is to strengthen the basis of this improvement,and has been successfully applied to sewage treatment.
