乌鲁木齐市河西污水处理厂改扩建工程设计

Design of Renovation and Expansion of Urumqi Hexi Sewage Treatment Plant

为了提高乌鲁木齐河西污水处理厂污染物消减量及区域污水处理量,对现状一期工程进行提标改造并进行二期工程扩建。一期提标工程采用原厂减量提质的改造方案,改造生化池并增设高速气浮工艺和反硝化深床滤池工艺;二期工程为全地下式双层加盖建设形式,采用改良AAO+MBR工艺,与一期工程出水一并经消毒后排放,最终实现总出水稳定达标。

In order to improve the pollutant reduction and regional sewage treatment capacity of Urumqi Hexi Sewage Treatment Plant,it is proposed to upgrade the current phase I project and expand the phase II project.The phase I of the standard improvement project adopts the original factory′s transformation plan of reducing vol⁃ume and improving quality,transforming the biochemical tank and adding high-speed air flotation process and denitrification deep bed filter process;the phase II of the project is a fully underground double-layer capped construction form,adopting the improved AAO+MBR process,and is disinfected together with the effluent from the first phase of the project before being discharged,ultimately achieving stable total effluent standards.
