科教中心污水和景观水处理工程实例

Sewage and Landscape Water Treatment Project in Science and Education Center

介绍了某科教中心的污水、景观水处理系统设计和实际运行情况。采用生化处理/高效固液分离器/过滤/消毒工艺,对整个科教中心的污水进行处理并回用,实现了零排放;采用景观水处理器循环处理/生态点缀的处理工艺,保证了景观水体主要水质指标达到《地表水环境质量标准》(GB 3838—2002)的Ⅴ类标准。两套处理系统产生的泥渣进行离心脱水后外运,同时对污水处理系统产生的臭气进行氧化、吸附处理后高空排放,实现了污水、臭气、泥渣的全面处理。

The design and practical operation of sewage and landscape water system in a science and education center were introduced. The biochemical treatment/efficient solid-liquid separator/filtration/disinfection process was used to treat and reuse the sewage from the science and education center, achieving zero discharge. The recycle treatment and ecological embellishment for landscape water were used to ensure that the treated landscape water attained Class V criteria specified in Environmental Quality Standards for Surface Water （GB 3838 -2002）. All the sludge from two sets of treatment systems was centrifugally dewatered and transported out, while odorous gases from sewage treatment system were oxidized, adsorbed and discharged to the atmosphere. All of the sewage, odorous gases and sludge were treated comprehensively.
