- 摘要:
- 江门市某污水处理厂总处理规模由20×104 m3/d扩容至22×104 m3/d，提标改造后出水水质由《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级B标准提升至一级A标准和广东省《水污染物排放限值》（DB 44/26—2001）第二时段一级标准的较严者。介绍了AAO-MBBR+滤布滤池+反硝化深床滤池的扩容提标改造工艺设计及运行效果，对用地条件受限的污水厂进行扩容提标改造具有一定的参考价值。
- Abstract:
- After the upgrading and expansion of a WWTP in Jiangmen, the total design capacity increased from 20×104 m3/d to 22×104 m3/d. The effluent quality has been upgraded from the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) to the stricter of the first level A criteria in GB 18918-2002 and the first level criteria of the second stage specified in Discharge Limits of Water Pollutant (DB 44/26-2001) in Guangdong Province. This paper elaborates the design and operation effect of the AAO-MBBR, cloth media filter, and denitrification deep bed filter (DDBF) process, which could provide reference to the upgrading of WWTP with limited land use conditions.
