摘要
人类的生存依赖水资源,工业的快速进步发展对水体产生负面影响,氮、磷过度排放使得水体持续恶化,随之而来的水污染成为不可小觑的重大环境问题,干扰人类正常生命活动,毁坏生态平衡,是国民经济绿色长远发展停滞的根源。现已通过多种技术对水环境进行改善修复,其中低C/N比污水脱氮除磷是解决环境问题的重要方法和研究热点。以传统工艺和新型工艺为切入点,以应用型和改进型为分类方法,对现今低C/N比污水脱氮除磷处理工艺进行总结,旨在为低C/N比污水脱氮除磷技术的发展提供新参考和新思路。
Human survival depends on water resources.The rapid progress and development of industry has a negative impact on the water body.The excessive discharge of nitrogen and phosphorus makes the water body continue to deteriorate.The subsequent water pollution has become a major environmental problem that cannot be underestimated,interfering with human normal life activities and destroying the ecological balance.It is the root cause of the stagnation of the green long-term development of the national economy.At present,a variety of technologies have been used to improve and repair the water environment,among which nitrogen and phosphorus removal from low C/N ratio sewage is an important method and research hotspot to solve environmental problems.In this paper,the traditional and new processes were taken as the breakthrough point,and the applied and improved processes were taken as the classification methods.The current low C/N ratio sewage nitrogen and phosphorus removal treatment processes were summarized,in order to provide some reference and new ideas for the development of low C/N ratio sewage nitrogen and phosphorus removal technology.
