摘要
文中以福建省某污水处理厂提标至一级A标准为例,对项目背景、设计方案、主要构筑物设计参数、运行效果和成本分析等进行介绍。针对目前二沉池沉降性能差、现有氧化沟工艺生物处理效果不佳等问题,将原有的“水解酸化+改良型Carrousel氧化沟+滤布滤池”工艺改造为可投加粉末活性炭的生物活性炭法(PACT)工艺,并增加“高效沉淀池+V型滤池+滤布滤池”深度处理工艺。正式投入运行之后,在2020年对污水处理厂出水进行了为期一年的水质检测,结果表明提标后的污水处理厂出水各项指标均达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A排放标准,且很好地解决了原有工艺的处理问题。
A wastewater treatment plant(WWTP) in Fujian Province is taken as an example to introduce engineering background, design scheme, main structure design parameters, operation effect and so on. In view of the poor sedimentation performance of secondary sedimentation tank and the poor biological treatment effect of existing oxidation ditch process, original "hydrolysis acidification + modified Carrousel oxidation ditch + cloth filter" process is transformed into powdered activated carbon treatment(PACT) with powdered activated carbon, and the advanced treatment process of "high efficiency sedimentation tank + V-type filter + cloth filter" is added. After formally put into operation, a one-year effluent quality test of WWTP is conducted in 2020, and results show that the effluent indexes of WWTP after upgrading all met the requirements of the first grade A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002), and it solves the problem of original process well.
