Problems solved by technology

Mercury-thallium mine waste dumps located in the Qianxinan region of Guizhou Province typically exhibit low nutrient content, low organic carbon, acidic pH, limited water holding capacity (WHC) and heavy metal (Hg, Tl, Sb, As) Potentially toxic concentration and other characteristics lead to strong biological toxicity, poor habitat, difficulty in natural plant growth, and extremely poor species richness and diversity in the mercury-thallium mine waste dump, which leads to the mercury-thallium mine waste dump. Continue to form a vicious cycle of large-scale exposure-intensified soil erosion and environmental pollution-enhanced habitat deterioration

Embodiment 1

[0023] Embodiment 1 of the present invention: a method for rapidly increasing the species richness and diversity of mercury-thallium ore waste dumps, by adding a small amount of industrial and agricultural waste to mercury-thallium ore waste as a compound modifier combined with phytoremediation to Rapidly increase the species richness and diversity of communities in the mercury-thallium mine waste dump environment; the industrial and agricultural wastes are red mud and fish manure respectively, and the fish manure added to the mercury-thallium mine waste The mass fraction of red mud is 4.0%, and the mass fraction of added red mud is 0.5%. The fish feces are collected from the aquaculture base, and the red mud is collected from the red mud stockpile of the aluminum factory. After the two are dried, ground and passed through a 10-mesh sieve, they are fully mixed for use.

[0024] Specifically include the following steps:

[0025] A: Mechanically or manually excavate and crush t...

Embodiment 2

[0028] Embodiment 2 of the present invention: a method for rapidly increasing the species richness and diversity of mercury-thallium ore waste dumps, by adding a small amount of industrial and agricultural waste to mercury-thallium ore waste as a composite modifier combined with phytoremediation to Rapidly increase the species richness and diversity of communities in the mercury-thallium mine waste dump environment; the industrial and agricultural wastes are red mud and fish manure respectively, and the fish manure added to the mercury-thallium mine waste The mass fraction of red mud is 5.0%, and the mass fraction of added red mud is 1.0%. The fish feces are collected from the aquaculture base, and the red mud is collected from the red mud stockpile of the aluminum factory. After the two are dried, ground and passed through a 10-mesh sieve, they are fully mixed for use.

Abstract

The invention discloses a method for rapidly increasing species richness and diversity of mercury thallium ore waste storage yard. According to the method, a small amount of industrial and agricultural waste is added into mercury thallium ore waste to serve as a composite modifier to be combined with phytoremediation, so that the richness and diversity of community species in the environment of the mercury thallium ore waste storage yard are rapidly increased; the industrial and agricultural waste are red mud and fish manure respectively, the mass fraction of fish manure added into the mercury thallium ore waste is controlled to be 4.0%-5.0%, and the mass fraction of the added red mud is controlled to be 0.5%-1.0%. According to the method, the fish manure and the red mud are ingeniously applied to the mercury thallium ore waste, so that the environmental condition of high-toxicity mercury thallium ore waste is remarkably improved, the purpose that waste is used for treating waste is achieved, a more suitable environment is provided for phytoremediation after the waste is utilized, and the ecological functions of water and soil conservation, carbon sequestration, biological diversity and the like can be achieved.

Description

technical field [0001] The invention relates to a method for rapidly increasing the species richness and diversity of mercury-thallium ore waste dumps, in particular to a method for increasing the species richness and diversity of communities in special highly toxic acidic mine tailings and waste. Background technique [0002] my country is a big mining country in the world. The development of mineral resources has promoted the development of my country's social economy and caused serious pollution to the environment. Mercury-thallium mine waste dumps located in the Qianxinan region of Guizhou Province typically exhibit low nutrient content, low organic carbon, acidic pH, limited water holding capacity (WHC) and heavy metal (Hg, Tl, Sb, As) Potentially toxic concentration and other characteristics lead to strong biological toxicity, poor habitat, difficulty in natural plant growth, and extremely poor species richness and diversity in the mercury-thallium mine waste dump, whi...
