SUMMARY1. Biostyr BAF曝气生物滤池2. Pyrofluid incineration流化床污泥焚烧
BIOSTYR

Capability of BIOSTYR生物滤池的特点
Up-flow filter, inlet channel from bottom, outlet on top 上向流滤池,底部渠道进配水,顶部出水
The specific gravity of media <1 滤料比重小于1
Perforated pipe aeration, saving equipment investment and maintenance costs穿孔管曝气,节省设备投资和维护费
Nozzle on top of filter, in treated water and easy to maintenance 滤头在滤池的顶部,与处理后水接触,易于维护
Backwash by gravity, need not pumps重力反冲洗,无须反冲洗水泵
- Aeration and air backwash share the air blower工艺空气和反冲洗用气共用鼓风机
- Aeration pipe could be set in the middle or bottom of filter, Nitration and denitration can be done in the same tank. 曝气管可布置在滤层中部或底部,在同一池中可完成硝化、反硝化功能
