Bioremediation of Soil Pollution Based on Fungal Immobilization Technology

: Fluxes of lead into the natural environment have been increasing in many regions of the world due to human activities, and lead fluxes have been reported to exceed those from natural processes. In recent years, due to the rapid development of industry in my country, the demand for lead has gradually increased. The large-scale mining and smelting of lead ore, the processing of lead-containing materials and other industries have vigorously developed and sharply increased lead-containing wastewater, waste gas, and waste to the natural world medium emissions. The main purpose of this paper is to study the bioremediation of soil pollution (SP) based on fungal solidification technology. The effects of different time, pH, temperature and initial lead concentration on the adsorption conditions of heavy metal lead were studied using the screened high lead-tolerant G strains. Experiments show that the heavy metal lead will hinder the germination of rapeseed seeds to a certain extent, but in the presence of microorganisms resistant to heavy metals, the phenomenon of inhibiting seed germination will be slowed down, and the final performance effect is that the germination rate of seeds is increased. However, when the concentration of heavy metal lead is too high, it will have a certain inhibitory effect on microorganisms and seeds. If it exceeds the tolerance range, it will be suppressed by heavy metals, and the higher concentration will lead to the death of both.
