Problems solved by technology

However, although many microalgae have a certain ability to adsorb heavy metal ions, the current adsorption efficiency of microalgae to heavy metal ions is limited, and many microalgae have poor tolerance to heavy metal ions, which greatly limits the use of microalgae in sewage. Applications in progress

Embodiment Construction

[0025] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0026] 1. Obtaining Chlorella W3

[0027] Chlorella sorokiniana W3 (Chlorella sorokiniana W3) of the present invention is obtained by separating from the water sample containing algae collected in the field, and its cell morphology is as follows: figure 1 As shown, the cells are round or oval, green, without flagella, and nucleated. It was identified by 18S rDNA sequencing that the microalgae belonged to the genus Chlorella of the phylum Chlorella. The microalgae was deposited in the China Center for Type Culture Collection (CCTCC) of Wuhan University, Wuhan City, Hubei Province, China on February 22, 2017. The preservation number is CCTCC NO: M2017058, and the Latin name is Chlorella sorokiniana W3. Chlorella sorokiniana W3, Latin name Chlorella s...

Abstract

The invention relates to a chlorella capable of removing heavy metals in water bodies with high heavy metal content. The chlorella was deposited in the China Center for Type Culture Collection on February 22, 2017, and the preservation number is CCTCC NO: M2017058. The Chlorella W3 of the present invention has high tolerance to heavy metal ions in the culture water body, and when growing in the water body containing high heavy metal content, it has a high removal rate of Zn, Ni, Co, and Cr, and has a high removal rate for Zn, Ni, Co, and Cr. The removal rate of Co is as high as 82%, and the removal rate of Zn and Cr is more than 90%, which is much higher than the removal efficiency of most microalgae currently used to remove heavy metals for Co, Zn and Cr, so it is especially suitable for treatment Polluted water with high content of Co, Zn and Cr. Besides, while removing heavy metals, the Chlorella W3 of the present invention can also remove nutrients such as N and P in the water body, so as to prevent the danger of eutrophication of the water body.

Description

technical field [0001] The invention relates to the fields of microalgae cultivation and sewage treatment, and more particularly relates to a chlorella capable of removing heavy metals in water bodies with high heavy metal content and applications thereof. Background technique [0002] The amount of heavy metals discharged by humans to the environment is increasing day by day, which not only seriously pollutes the soil and water environment, but also causes great harm to human health. For the treatment of heavy metal polluted water bodies, the traditional methods mainly include physical, chemical and biological methods, including precipitation method, chelating resin method, polymer trapping agent method, natural zeolite adsorption method, membrane technology, activated carbon adsorption process, ion exchange method, etc. . These methods have better purification effects, but the process is complicated, the operation is cumbersome, the cost is high, and it is not suitable fo...
