摘要
介绍了北方典型小城镇污水厂提标改造设计的特点。为保证脱氮、除磷的效果同时兼顾中水回用的需求设计采用先进的平板膜MBR工艺,这也是平板膜在该地区的首次应用。同时,新增了膜格栅池对现状A^2/O生物池进行改造;出水采用紫外消毒工艺,出水水质达到并优于城镇污水处理厂污染物排放标准(GB 18918-2002)的一级A排放标准。
The design of upgrading and reconstruction in the northern small urban sewage treatment plant were introduced.To ensure the phosphorus and nitrogen removal efficiency and balance the needs of water reuse,the advanced MBR process was adopted.This is the first application about flat membrane bioreactor in the region.Increasing the fine grille pool,transforming the status A^2/O biological pool,disinfecting by ultraviolet radiation,the effluent quality met the first level A criteria specified in the discharge standard of pollutants for municipal wastewater treatment plant（GB 18918—2002）.
