摘要
当下,我国城市污水处理厂的主要矛盾已由有机物的去除转向氮、磷等营养物的去除。而城市污水处理厂目前普遍采用的传统生物脱氮除磷工艺因其自身的特点及城市污水特征,导致氮、磷污染物去除效率无法满足愈发严格的国家标准。针对这种问题,通过对同步硝化反硝化、厌氧氨氧化、反硝化除磷、短程硝化反硝化这些新型技术及其研究现状进行介绍,探究新型生物脱氮除磷技术在城市污水处理领域中应用的优越性与合理性。并基于多菌群协同除污机理,结合我国城市污水处理可持续发展现状,探索未来的技术发展方向。
At present,the main issue of urban wastewater treatment plants(WWTPs)at home has been transformed from the removal of organic matter into the removal of nutrients such as nitrogen and phosphorus.However,traditional biological nitrogen and phosphorus removal process which are commonly used in urban WWTPs due to its own characteristics and the characteristics of urban wastewater,leading to nitrogen and phosphorus pollutant removal efficiency can not meet the increasingly stringent standards.In response to this problem,the novel technologies of simultaneous nitrification and denitrification,anaerobic ammonia oxidation,denitrifying phosphorus removal,short-cut nitrification and denitrification,and their research status are introduced,and the application of new biological nitrogen and phosphorus removal technology in the field of urban wastewater treatment are explored.Based on the mechanism of multimicrobial community collaborative decontamination,combined with the current situation of sustainable development of urban sewage treatment at home,the future technical development direction is explored.
