- 摘要:
- 为使出水水质达到《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》（DB 32/1072—2018）标准，对太湖流域的8座污水处理厂进行了提标改造。在分析现状实际进出水水质、主体构筑物的参数、运行情况的基础上，提出了包括预处理、生化处理、深度处理、污泥处理段的提标改造工艺技术路线，实际运行效果均稳定良好。分析了工程直接费和增加的运行成本，并总结了不同进水构成及建设条件下各种工艺组合的适用性以及提标改造工程在设计、建设、运行中的一些相关经验，可为其他类似工程提供参考。
- Abstract:
- Eight wastewater treatment plants in Taihu Lake basin were upgraded to make the effluent quality meet Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area (DB 32/1072-2018). Based on the analysis of the actual influent and effluent quality, parameters of the main structures and operation of the current situation, the upgrading technical route of pretreatment section, biochemical section, advanced treatment section and sludge treatment was proposed, and stable and good operational performance was obtained. The direct costs and increased operating costs of the projects were analyzed. The applicability of various process combinations under different influent composition and construction conditions and some relevant experience in the design, construction and operation of upgrading projects were summarized to provide reference for other similar projects.
