摘要
废水组分复杂且资源丰富,研发经济高效的回收技术能够缓解地球资源匮乏的窘境。在文献调研和现场调研的基础上,本文重点论述了废水中重金属、有机溶剂、营养元素和无机盐四大类物质回收技术,并总结目前各个技术优缺点和使用范围,同时展望了废水资源回收技术未来发展,为污水处理厂或企业废水资源回收技术升级改造提供科学依据。
Developing economic efficient recycling technology can alleviate the scarcity of resources.Based on the literature survey and practical investigation,the recovery technologies of heavy metals,organic solvents,nutrient elements and salt were summarized.The characteristics and applicable scopes of these technologies were analyzed,and the development of wastewater recycling was prospected.It was expected that this work can provide the scientific basis for the wastewater recycling technology update for wastewater treatment plants or enterprises.
