Abstract：
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.
Keywords：wastewater; heavy metal; organic solvent; nutrient element; salt; recovery technology;
