Research on the Control of Biomass and Heavy Metal Pollution

Abstract

Faced with the increasing loss of resources and the worsening of environmental pollution, the country is also paying more and more attention to the recycling of resources and pollution control. At present, biomass as a new energy can improve the utilization of resources and environmental conditions. This paper focuses on the basic content of biochar, the status of soil heavy metal pollution and the effect of biochar on the control of heavy metal pollution. Studies have shown that biochar can convert part of exchangeable heavy metals in soil into a stable state through passivation, and the other part of heavy metals can be absorbed by plants to achieve the purpose of repairing soil plants, thereby indirectly improving soil characteristics. In addition, biochar can also use chemical leaching method to remove heavy metal pollutants in soil by leaching solution to improve soil heavy metal pollution. In order to better optimize the use of resources and improve environmental pollution, we should explore the interaction between biomass energy and environmental media more deeply, and innovate the technologies and methods of birth matter energy in pollution control. The combination of biomass and heavy metal pollution control can not only promote more in-depth research on biomass properties, but also make great contributions to human resource recovery and environmental pollution control.
