摘要
在东源县县城生活污水处理厂一期工程尾水提标工程中,通过采用"曝气生物滤池+高效沉淀池+精密过滤"工艺,出水水质指标由原本的国家《城镇污水处理厂污染物排放标准》(GB18918-2002)一级标准(A标准)提升至国家《地表水环境质量标准》(GB3838-2002)Ⅳ类水体水质标准。详细介绍了尾水提标工程的设计思路、工艺流程、主要构筑物的设计参数及设备配置,并总结了工艺设计特点、经济指标及运行效果,对于同类型污水处理厂的提标改造具有借鉴意义。
In the Upgrading Project of the First Phase of Dongyuan County Municipal WWTP, by adopting the process of＂Biological Aerated Filter ＋ Efficient Sedimentation Tank ＋ Precision Filtration＂, the effluent water quality indicators improve from Class A of the National Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002） to Class IV of the National Environmental Quality Standard for Surface Water （GB3838-2002）. The Design ideas, process flow, design parameters of main structures, and equipment configuration were introduced in detail. The characteristics of process design, economic indicators, and operation effect were summarized. This project can be used for reference for the upgrading and reconstruction project of the same types of wastewater treatment plant.
