Problems solved by technology

However, this method only uses a single microbial repair technology, and the repair efficiency has not been verified by experiments, which is not convincing.
Moreover, this method is only effective for chromium in soil heavy metal pollutants, other major heavy metal pollutants, such as copper, lead, mercury, arsenic, etc. are still not effectively treated, and the soil pollution cannot be completely improved, which limits practical application of this method

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the examples.

[0030] Soil remediation in coal mining areas using trichomes and mixed inoculants:

[0031] (1) Under the condition that the climatic temperature is higher than 10 ℃, the seeds of triceratops are laid flat on the ground covered with plastic film, and exposed to sunlight for a cumulative time of 24 hours, and then the lime water with a concentration of 1% is used. Soak the seeds, take out the grass seeds after soaking for 2 hours, spread the grass seeds evenly on the sandy soil, cover them with moistened cotton gauze, keep the temperature at 25 °C, water 3 times a day, and the amount of watering a single time is enough to moisten the seeds. Cotton gauze shall prevail until the grass seeds germinate;

[0032] (2) According to the ratio of 25 parts of garden soil, 13 parts of humus, 5 parts of carbonized rice husk, and 4 parts of chicken manure, the seedling matrix was prep...

Abstract

The invention belongs to the technical field of soil bioremediation, particularly relates to a method for remedying soil of a coal mining area, and discloses a method for achieving plant-microorganismcombined remediation on soil of a coal mining area. According to the method, trisetum bifidum seeds are exposed to the sun, soaked and sprouted, then the sprouted trisetum bifidum seeds are sown in aplug containing a seedling grow matrix for emerging and seedling grow, then a mixed bacterium agent formed by acidithiobacillus ferrooxins, trametes versicolor and glomus coronatum is applied, afterthe polluted soil of the mining area is leveled, improved and ditched, seedlings are buried in ditches for soil return seedling covering, field management is carried out, and after growing for 90-120days, the seedlings are harvested. Through the method, after one or more times of planting, the physicochemical indexes of the soil of the coal mining area can be obviously improved to reach the normal standard, a new way is provided for soil control of wide coal mining areas, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of soil bioremediation, in particular to a method for soil restoration in coal mining areas. Background technique [0002] Coal has always accounted for a relatively high proportion of my country's energy consumption, although with the implementation of the concept of green development and the implementation of policies such as the coal industry actively resolving excess capacity in 2016, the proportion of coal in primary energy consumption has been declining for five consecutive years. The trend has dropped from 70.2% in 2010 to 62.3% in 2016. However, for a long time to come, my country's energy structure will still be dominated by coal. In the process of coal development and utilization, it will inevitably cause damage to the ecological security of the mining area, which is embodied in soil pollution and damage, water pollution and damage, air pollution, noise pollution, damage to biological resources, and...
