随着我国"双碳"目标的提出和水处理行业提标改造的重点落在生物脱氮,污水处理厂从关注满足排放许可限制转向实现碳中和、能量自给及资源回收.厌氧氨氧化(Anammox)技术凭借无需外加有机碳源、占地面积小、污泥产量少以及脱氮效率高等节能降耗与碳减排优势,代表着未来污水生物脱氮的发展方向.基于已有研究成果,梳理对比了传统脱氮与Anammox反应的发展历程;重点综述了新兴短程硝化耦合Anammox(PN-A)工艺、短程反硝化耦合Anammox(PD-A)工艺和甲烷型反硝化耦合Anammox(DAMO-Anammox)工艺在城市主流工况的应用进展;详细探讨了主流Anammox工艺面临低温、进水负荷不均和光照等环境因素冲击时,可施行的"侧流污泥补充至主流""侧流污水间歇性补充至主流""驯化生物膜颗粒"等内源性以及外源性的强化调控策略及内在机制;最后围绕分子生物学技术、材料科学、数字信息技术和管理政策,对加快Anammox生物脱氮技术的创新发展与推广应用进行了展望.
Advances in application and reinforced control of Anammox nitrogen removal process based on carbon emission reduction
With the proposal of China's"dual carbon"goal and the focus of upgrading the water treatment industry to biological nitrogen removal,sewage treatment plants have shifted from focusing on meeting emission permit limits to realizing carbon neutrality,energy self-sufficiency and resource recovery potential.Anaerobic ammonia oxidation(Anammox)technology,with the advantages of no additional organic carbon source,small footprint,small sludge production and high nitrogen removal efficiency,represents the future development direction of biological nitrogen removal in sewage,with energy saving,consumption reduction and carbon emission reduction.Based on the existing research results,the discovery history of traditional nitrogen removal and Anammox reaction was summarized and compared.The application progress of emerging partial nitrification and Anammox(PN-A),partial denitrification and Anammox(PD-A),and anaerobic methane denitrification and Anammox(DAMO-Anammox)processes in urban mainstream conditions were reviewed.The endogenous and exogenous regulation strategies and their internal mechanisms,which could be implemented when the mainstream Anammox process was confronted with environmental factors such as low temperature,uneven influent load and light,were explored in detail.These strategies include"side-flow sludge supplement to mainstream""side-flow sewage intermittent supplement to mainstream"and"acclimated biofilm particles",and so so on.Finally,future directions for accelerating the innovative development and application of Anammox nitrogen removal technology were proposed in terms of molecular biology technology,material sciences,digital information technology,and management policies.
