Organic pollution control of agricultural land based on straw biochar

ABSTRACT Organic pollution of agricultural land will cause environmental problems and agricultural economic effects. To explore the reliable effect of remediation of organic pollution in agricultural land, wheat straw biochar was prepared in this paper. Moreover, this paper uses experimental research and comparison methods to study the difference in the adsorption performance of biochar at different pyrolysis temperatures on polycyclic aromatic hydrocarbons (PAHs) and the effect of pyrolysis biochar on the availability of phenanthrene and pyrene microorganisms in the soil at the same temperature. Additionally, statistical methods are utilised in this research to do analytics and data processing on test data, and test findings are visually displayed using a combination of graphs and tables. Finally, to understand the experimental research findings, this system employs analytical approaches. The results of the experiment show that wheat straw biochar can effectively reduce soil organic pollution, which can expand the research on the restoration of other crop straw biochar on agricultural land.
