摘要 随着水资源环境保护的深化,城镇污水厂出水指标逐步提升,由国标的一级B逐步过渡至一级A排水标准。为应对排放标准提高,湛江市某生活污水处理厂提标改造工程主体工艺采用“曝气生物滤池+反硝化深床滤池”工艺,兼顾了过滤、硝化、反硝化脱氮及除磷功能。经提标后污水厂出水水质可稳定达到国家一级A标准(GB18918-2002)及广东省地方标准《水污染物排放限值》(DB44/26-2001)较严值。 With the deepening of environmental protection of water resources, the effluent indicators of urban sewage treatment plants have gradually increased,from the national standard Grade B to Grade A drainage standard. In response to the increase in discharge standards, the main process of the upgrading and renovation project of a domestic sewage treatment plant in Zhanjiang City adopts the “aerated biological filter + denitrification deep bed filter” process, which takes into account the functions of filtration, nitrification, denitrification and denitrification and phosphorus removal. The effluent quality of the sewage treatment plant can stably reach the national level A standard(GB18918-2002) and the stricter value of the local standard of Guangdong Province “Water Pollutant Discharge Limits”(DB44/26-2001) after the upgrade.
