The technical difficulties of using microbial technology to repair abandoned areas in coal mines

"Font-size: 14px; font-family: SimSun;" Our country has used a considerable amount of technology in restoring wasteland in coal mine areas, including microbial technology, which is said to have made good progress in theoretical research, but in reality, the effect of microbial technology in the application is not obvious, mainly the following problems are difficult to solve!span style"font-size: 14px; font-family: SimSun; "span-style"font-size: 14px; font-family: SimSun; the first is: the microbe's single-mindednessSpecific microorganisms act only on certain or certain chemical componentsThe microbial disposal of heavy metal pollution in abandoned areas of coal mining areas is much more complex than the microbial degradation of organic pollutantsFor polycyclic aromatic hydrocarbons that are difficult to biodegrade, further research is neededspan style"font-size: 14px; font-family: SimSun; ""span style" font-size: 14px; font-family: SimSun;" the second is that the mining waste site type is different, the microbiome is also different, when the concentration of pollutants in the rock is too low and not enough to maintain the microbial community, microbial repair is difficult to workThe use of bio-microbiological joint and engineering measures to repair is the main way to repair waste sites in different types of mining areasspan style"font-size: 14px; font-family: SimSun;style"style" font-size: 14px; font-family: SimSun; "font-size" "font-size"; font-family: SimSun; " style"font-size" "font-size: 14px; In the current national environmental protection efforts continue to increase and the social awareness of environmental protection is increasing, microbial ecological restoration technology needs to be faster from the laboratory to practical applications
