Embodiment 1

[0026] A method for treating ionic rare earth tailings based on biogas engineering is realized through a series of effective measures such as pretreatment of ionic rare earth tailings, planting of energy crops, soil ecological restoration, and reuse of energy crops. The details are as follows:

[0027] 1. Pretreatment of ionic rare earth tailings: select the pretreated base 1 as the experimental base of this embodiment to carry out the restoration experiment;

[0028] 2. Planting of energy crops and soil remediation: screening of energy plants with strong adaptability to rare earth tailings, the selected varieties include: hybrid Pennisetum, miscanthus, mulberry, pokeweed, and imperial bamboo grass. After screening, the root system of imperial bamboo grass Developed, strong resistance to barren environment, and its vegetation can be used for animal husbandry, and it is more suitable for the present invention as an energy plant. The details are as follows:

[0029] . Seed...

Abstract

The invention provides an Ionic rare earth tailing treatment method based on biogas engineering, which is characterized in that biogas residues and biogas slurry generated by the biogas engineering are used as fertilizers after being pretreated, energy crops are planted in the rare earth tailings, and the soil of the rare earth tailings is transformed by an ecological restoration technology. In addition, by means of the technical mode, self-circulation survival of the biogas station-rare earth tailing ecological domain is achieved, and huge economic benefits are created. Meanwhile, the rare earth tailings are connected with reprocessing and reutilization of energy crops, and other marginal benefits under treatment based on the technical mode are achieved.

Description

technical field [0001] The present invention relates to the technical field of new agricultural ecological treatment, in particular to a method for treating ionic rare earth tailings based on a biogas project. By using biogas residues and biogas fluids in biogas projects to plant energy crops, the "digestion of biogas residues and biogas fluids - energy Crop planting-soil ecological restoration-energy crop reuse" ecological energy farm model. Background technique [0002] Ionic rare earth tailings refer to the land that is destroyed and occupied by ionic rare earth mines due to mining, and has been damaged after the stop of mining, and will not be usable without treatment. It is a kind of mining wasteland, and the mining method is mostly open-pit mining. , leading to great damage to ecological vegetation, soil, landscape and surrounding environment. A typical example is the rare earth mining area in Dingnan County, Ganzhou, China. The soil characteristics after mining are a...
