- 摘要:
- 韶关市某市政污水处理厂提标改造项目规模10.0×104 m3/d，出水标准由《城镇污水处理厂污染物排放标准》（GB 18918—2002）二级标准提升至一级A标准和广东省地方标准《水污染物排放限值》（DB 44/26—2001）第二时段一级标准中的较严值。针对现状氧化沟因采用表面曝气而氧气利用率低、污泥大量沉积在池底的问题，对氧化沟进行了技术改造，改用底部微孔曝气器，并增设曝气生物滤池+上向流反硝化滤池深度处理单元，实际出水水质稳定达到了《地表水环境质量标准》（GB 3838—2002）Ⅲ类标准（TN除外）。
- Abstract:
- The scale of a municipal wastewater treatment plant upgrading project in Shaoguan City is 10.0×104 m3/d, and the effluent standard is upgraded from the second level limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) to the stricter of the first level A limit and the first level limit in the second period specified in the Guangdong Provincial local standard Discharge Limits of Water Pollutants (DB 44/26-2001). To solve the problems of low oxygen utilization rate and large amount of sludge deposition at the bottom of the oxidation ditch due to surface aeration, the oxidation ditch was reconstructed as follows: the microporous aerator was adopted at the bottom of the tank, and the advanced treatment units including biological aeration filter and upflow denitrification filter were added. The actual effluent quality stably reached the class Ⅲ limit specified in Environmental Quality Standards for Surface Water (GB 3838-2002) (except TN).
