Description

一种土壤原位化学修复的辅助方法
技术领域
本发明是一种新型的土壤原位化学修复的辅助方法，应用于土壤污染治理的相关领域。
背景技术
土壤污染修复技术则是指采用化学、物理学和生物学的技术与方法以降低土壤中污染物的浓度、固定土壤污染物、将土壤污染物转化成为低毒或无毒物质、阻断土壤污染物在生态系统中的转移途径的技术总称。其中原位化学修复技术(原位化学氧化/还原、固化/稳定化等)，因其易操作、工期短、效果好，得到广泛应用。但是，因为土壤的自身特性(固液气三相共存的多相体系)，且土壤中次生的胶体对污染物和化学药剂有吸附作用，使得污染物在土壤中分布不均，难以清除；土壤修复所注入的化学药剂也无法和相应污染物充分接触反应，形成局部的污染物残留或是局部的药剂过量造成成为二次污染。
发明内容
本发明方法：在原位化学修复药剂注药管的原位或周围，插入振动棒或附着振动板等方法，迫使一定范围的土壤系统振动，使固液气三相发生相对位移，药剂在土壤间隙中缓慢流动，胶团解体，加速药剂均化和化学反应速率(如图1：振动前后效果对比示意图)。可以调整振动设备/工具的频率，以土壤系统共振频率最佳，使动能高效传递，提高原位化学反应的效率和效果。以此方法提高原位化学修复的效果并降低二次污染的可能。
附图说明
图1：振动前后效果对比示意图。

1.方法1：使用振动设备/工具，迫使一定范围的土壤系统振动，从而提高原位化学反应的效率和效果。
2.方法2：利用共振原理提高土壤原位化学修复效果。
