摘要
简述了城镇污水厂面临的高排放标准挑战,分析了污水处理去除目标及重点难点,根据不同工艺组合的预期效果,提出高排放标准下城镇污水厂提标改造重点难点是提高生物处理率,强化生物硝化、反硝化,并以工程实例介绍了提标改造工艺,强调以稳达标为核心,因地制宜地进行城镇污水厂的提标改造,实现低耗高效的运营管理。
The high emission standard challenges faced by municipal wastewater plants were briefly described,and the targets and difficulties of wastewater treatment were discussed.According to the expected effects of different process combinations,it was proposed that the most important and difficult point of upgrading the municipal wastewater treatment plant under high emission standards was to increase the biological treatment rate and to strengthen biological nitrification and denitrification process.And furthermore,the introduction of the project case was used to describe the upgrading process.It was emphasized that the standard raising and transformation of municipal wastewater plants should be carried out according to local conditions,so as to realize low consumption and high efficiency operation and management.
