Soil microalgae of mining area, separation and purification method for soil microalgae of mining area and application of soil microalgae of mining area

Abstract

The invention provides soil microalgae of a mining area, a separation and purification method for the soil microalgae of the mining area and application of the soil microalgae of the mining area. Thesoil microalgae of the mining area are separated and purified from biological crusts of surfaces of tailings and comprise one or more selected from Chlorella, Cylindrotheca, Diatom, Nitzschia, Schizochytrium, Dunaliella, Scenedesmus, Nannochloropsis oculata, Chlamydomonas, Tetraselmis and Eudovina. The soil microalgae of the mining area, provided by the invention, are separated and purified from the biological crusts of the surfaces of the tailings; the obtained microalgae are relatively extensive in variety; and the obtained microalgae have relatively good adsorption and absorption capabilityto contaminants such as heavy metals and phosphorus in contaminated soil and water and then can effectively treat the contaminants such as the heavy metals and phosphorus in the contaminated soil andwater, so that the treatment cost of the contaminants such as the heavy metals and phosphorus in the contaminated soil and water is reduced greatly.

Description

technical field [0001] The invention relates to the field of microalgae biotechnology, in particular to a soil microalgae in a mining area and its separation and purification method and application. Background technique [0002] Soil microalgae, as an important part of soil microorganisms, refer to the algae groups of various groups such as soil surface, subsurface, and soil formation, succession, and soil composition, such as lithophytic, aquatic-terrestrial algae, etc. , paddy fields and soils with high organic matter content are most widely distributed. [0003] Soil microalgae are rich in species. In the environmental field, microalgae, as one of the organisms with adsorption capacity, has the advantages of high photosynthetic rate, fast reproduction, and strong adaptability to the environment. Nowadays, there are a large number of research reports on microalgae as biosorbents in sewage treatment and soil pollution applications. The oil produced by some microalgae such...

Problems solved by technology

[0007] In view of this, the present invention aims to propose a kind of mining area soil microalgae, which is purified from the mining area soil crust with high heavy metal content, and its tolerance to heavy metals and adaptability to extreme environments are better, and more It solves the problem that the heavy metals, phosphorus and other pollutants in the existing polluted soil and water are difficult to deal with and the treatment cost is high
