太原精神病院污水处理系统改建为中水处理系统的工程设计

The design of reconstruction of water reuse engineering of Taiyuan Psychiatric Hospital

太原精神病医院将现有生活污水处理系统改建为中水回用系统,平均日处理水量100 m3。工程设计充分考虑了对原有设施的利用,生物处理单元采用生物接触氧化法。为减少污水提升次数,调节池设在生物处理单元之后。通过延长水力停留时间缓解水量、水质波动对沉淀、生物处理单元的不利影响,投入运行后效果良好。

The wastewater treatment engineering of Taiyuan Psychiatric Hospital was recon structed to water reuse engineering. The average treatment capacity was 100 m3/d.The utilization of existing installations was fully take into account therefore the bio-contact oxidation process was used. The regulating tank followed the biological treatment unit to reduce pumping time. The unfavorable influence of fluctuation of water flow and water quality to the settling unit and biologi cal treatment unit was offset by extending HRT. It achieved good results.
