报告题目：生物炭与农田有机污染土壤生态修复

报告摘要：

生物炭是生物质限氧热解形成的富碳材料，将废弃生物质炭化被认为是一种非常有前景的碳汇技术。随着我国双碳战略的实施，生物炭研究与应用引起国内外的广泛关注。报告人主要介绍生物炭在农田有机污染土壤绿色修复领域中的研究与应用，并围绕生物炭改性及其对抗生素的催化降解，结合密度泛函理论计算，阐述其对土壤有机污染与氮磷流失的协同控制机理。

TITLE： 

Biochar and remediation of organic contaminated farmland soil

ABSTRACT：

Biochar is a carbon-rich material of waste biomass pyrolysis under oxygen-limited conditions, which is considered as a promising carbon sequestration technology. With the implementation of Carbon Neutrality strategy in China, biochar has received increasing attention because of its significant environmental impact and outstanding agricultural application potential. The discussion will focus on the research and application of biochar in the field of green remediation of organic-contaminated farmland soil. To developing an in-situ soil remediation technology for simultaneous catalytic degradation of contaminants and nutrition supplementation, engineered biochars were successfully synthesized by using a simple co-precipitation method. We have revealed the transition states and degradation pathways of antibiotics by biochars. Combined with density functional theory, the interfacial interaction mechanism between antibiotics degradation and phosphate sorption was investigated.
