生物炭治理水稻砷污染的研究进展

Research Progress in the Treatment of Arsenic Pollution in Rice by Biochar

当前,水稻种植中的土壤砷污染问题已经成为我国所面临的一个重要环境污染问题。为了保证水稻的产量以及粮食安全,亟需采取相应的措施对受污染的土壤进行修复和治理。近年来,在众多治理措施中,生物炭以其独特的吸附特性,便利的原料来源以及有效的修复效果成为了一个治理土壤重金属污染的热点,该文介绍了生物炭的基本性质,对生物炭在治理土壤污染方面的研究进行了简要总结,分析了在研究过程中存在的问题并提出相应的对策,以便对废弃物资源化,水稻安全生产提供参考和依据。

At present, soil arsenic pollution in rice planting has become an important environmental pollution problem in China. In order to ensure the yield of rice and food security, it is urgent to take appropriate measures to repair and control the contaminated soil. In recent years, during the control measures,biochar has become a focus of a soil heavy metal pollution for its unique adsorption characteristics, convenient sources of raw materials and effective remediation effect, this paper introduces some basic properties of biochar, some soil pollution in the governance aspects of the research are briefly summarized, analysis the problems existing in the research process and put forward the corresponding countermeasures, hoping to waste resources, provide some reference and basis for the safe production of rice.
