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。

报告人简介

报告人于2020年在上海交通大学获得博士学位,博士就读期间获国家留学基金委的资助在美国农业部盐土实验室进行博士联合培养。在Applied Catalysis B: Environmental、Journal of Hazardous Materials、Chemical Engineering Journal等期刊发表SCI论文15篇,单篇IF>20的1篇,单篇IF>10的4篇;以第一发明人获授权专利2项。2020年获上海市“超级博士后”和上海市科技进步二等奖,2022年获江苏省科技进步三等奖等奖励;主持国家自然科学基金青年项目和中国博士后基金面上项目各1项。

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.
