一种新型污水处理工艺在生活污水处理厂的应用
|
摘要
某公司污水处理厂拟采用"BioDopp生化反应器+曝气生物滤池+滤布滤池"的工艺,出水达到《地表水环境质量标准》(GB 3838—2002)V类限值,BioDopp工艺利用氧化沟的混合液内回流和A~2/O不同功能分区相结合的设计理念,借助CASS工艺前置选择区的模式,通过空气提推技术作为流体动力,在低能耗条件下可实现污泥在反应器内的高回流比,有着能耗低、占地少等优点,是一种具有脱氮除磷功能、实用性较强的新型污水处理工艺。
"BioDopp biochemical reactor + Biological aerated filter+ Filter cloth filter" process is proposed by a sewage treatment plant,the effluent of which reaches V class limit of surface water environment quality standard(GB3838-2002).A mixture of oxidation ditch in reflux and A~2/O the design concept of combination of different functional partition are used in BioDopp process,with the help of CASS process preposed choice area,taking the air fluid push technology as a driving force,under the condition of low energy consumption,high reflux ratio of sludge in the reactor can be realized,with the advantages of low energy consumption and less land.It is a kind of denitrification and phosphorus removal function and practical new type of sewage treatment process.
