Abstract

The invention discloses an integrated photobioreactor for efficiently treating and rapidly harvesting rare earth tail water by using flocculated microalgae, and relates to a photobioreactor for treating and harvesting rare earth tail water. The technical problems that an existing rare earth tailing wastewater treatment method is high in cost, the wastewater treatment volume is relatively small, and microalgae are inconvenient to recycle after wastewater is treated through microalgae are solved. The influence of external conditions on the growth of the flocculation microalgae is adjusted through constant-temperature water bath heating, lighting equipment and an aeration device, the existing problems of separation and recovery of co-flocculation microalgae and wastewater are solved, and the separation of the microalgae and the treated wastewater is realized by opening knobs of water outlets and utilizing gravity flow. Liquid is discharged through multiple stages of water outlets, so that the microalgae recycling efficiency is improved. The device disclosed by the invention integrates efficient treatment of the rare earth tail water and rapid harvesting of the flocculated microalgae.

Description

technical field [0001] The invention relates to a photobioreactor for treating and harvesting rare earth tail water. Background technique [0002] my country is a country with a large reserve of rare earth resources in the world. It is not only rich in reserves, but also has a complete range of minerals and rare earth elements, and high grades of rare earths. The rare earth processing industry has formed an industrial chain integrating mining, beneficiation, separation, smelting and processing. The rare earth industry is an important pillar industry in Ganzhou City and plays a decisive role in promoting the economic development of southern Ganzhou. In recent years, Ganzhou has made every effort to build "China's Rare Gold Valley" to promote new materials and application industries of rare earth, tungsten and other non-ferrous metals to high-end. The rare earth tailings wastewater produced by the rare earth industry, as a large amount of pollutants, affects the local enviro...
