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 a method for treating ionic rare earth tailings based on a biogas project. The biogas residue and biogas slurry produced by the biogas project are used as fertilizer after pretreatment, and energy crops are planted in the rare earth tailings. Ecological restoration technology Realize the transformation of the soil of rare earth tailings. Moreover, this technical model realizes the self-circulation survival of "biogas station-rare earth tailings ecological domain", creating its huge economic benefits. At the same time, rare earth tailings are connected to the reprocessing and reuse of energy crops and other marginal benefits under the governance of this technology model.

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...
