- 摘要:
- 污泥磷回收是解决磷资源匮乏的战略需求，也是废物资源化的有效手段。因有毒物质的存在，污泥磷释放是磷回收的重要前提。根据不同的污水处理工艺及后续污泥处理处置技术，介绍了三种主要富磷污泥中磷的赋存形态及转化机制，提出了识别污泥中磷的赋存形态对磷回收技术开发的重要性。基于目前对污泥中磷赋存形态的认识，以酸溶为代表的化学法和以厌氧消化为核心的物化-生物组合技术是污泥磷释放的有效手段。针对污泥中磷回收技术研究现状及存在的问题，结合污泥综合处理处置的理念，指出开发与污泥厌氧资源化相适应的磷回收技术成为可持续的发展方向。
- Abstract:
- Phosphorus recovery from sludge is a strategic demand to solve the shortage of phosphorus resources and an effective means of waste recycling. Phosphorus release has become an important prerequisite for phosphorus recovery from sludge due to the presence of toxic substances. The occurrence states and transformation mechanism of phosphorus in three main phosphorus-rich sludge were introduced based on different sewage treatment processes and subsequent sludge treatment and disposal technologies. The importance of identifying phosphorus occurrence states in sludge for phosphorus recovery technology development was proposed. Based on the current understanding of the phosphorus occurrence sates in sludge, the chemical method represented by acid extraction and the physicochemical biological combination technology with anaerobic digestion as the core were effective methods of phosphorus release from sludge. The current research status and existing problems of phosphorus recovery technology in sludge combing the concept of comprehensive treatment and disposal of sludge were discussed. It is pointed out that the development of phosphorus recovery technology suitable for anaerobic resource utilization of sludge has become a sustainable development direction.
