农田土壤汞污染修复技术研究

Study on Remediation Technology of Mercury Pollution in Farmland Soil

对揭阳市某农田土壤重金属污染现状进行了研究,提出深翻混合、深翻置换和分层置换3种不同的汞污染修复技术,并在现场分别开展试验研究,对修复技术的方法、应用、效果进行了介绍。研究结果表明,采用深翻置换和分层置换技术可以达到修复目标,为今后开展农田汞污染修复治理提供借鉴意义。

The status of heavy metal pollution in farmland soil of Jieyang was studied. Three different remediation technologies of mercury pollution were proposed,including deep ploughing and mixing,deep ploughing,and layered replacement. The field experiments were carried out,and the methods,applications and effects of remediation technologies were introduced. Results showed that deep ploughing replacement and layered replacement technology could achieve the goal of remediation,and provide a reference for the future remediation of mercury pollution in farmland.
