摘要:

低碳高效的Anammox技术在污水处理中对实现“双碳”目标具有潜力,并为污水处理厂工艺带来技术变革。对传统脱氮和Anammox脱氮进行了比较,指出Anammox在节能降耗和温室气体减排中具有优势;分析了实现短程硝化Anammox(PNA)和短程反硝化Anammox(PDA)稳定获得NO2-的控制策略,其中游离氨(FA)、温度、DO和间歇曝气是PNA的重点调控因子,而碳氮比是PDA的重要控制因素。基于控制原理,Anammox技术在多种污水中具有应用前景,但PNA更适合污泥消化液、污泥脱水液和垃圾渗滤液的处理,PDA则更适合低温、低NH4+-N的主流污水,以及城市污水和NO3-污水混合污水的处理。未来研究的重点在于:界定适于PNA和PDA的污水种类,考察污水组分对PNA/PDA的影响及响应,中试验证各种污水的PNA/PDA,改造升级传统脱氮以实现PNA/PDA。

Abstract:

Anammox technology with low carbon and high efficiency has the potential to achieve the "carbon peaking and carbon neutrality goals" in wastewater treatment, and brings technological changes to wastewater treatment plant processes. Traditional denitrification and Anammox denitrification were compared, and it was pointed out that Anammox has advantages in energy saving and greenhouse gas emission reduction. The control strategies to achieve stable NO2- acquisition by PNA and PDA were analyzed, among which FA, temperature, DO and intermittent aeration were the key control factors of PNA, while carbon-nitrogen ratio was an important control factor of PDA. Based on the control principles, Anammox technology has promising applications in a variety of wastewaters, but PNA is more suitable for the treatment of sludge digestion liquid, sludge dewatering liquid and landfill leachate. While PDA is more suitable for the treatment of mainstream wastewater with low temperature, low NH4+-N, and mixture of municipal wastewater and NO3- wastewater. Future research will focus on defining wastewater types suitable for PNA and PDA, examining the effect and response of effluent components on PNA/PDA, demonstrating PNA/PDA for various effluents in pilot tests, and upgrading traditional denitrification to realize PNA/PDA.
