重金属污染土壤原位稳定化药剂投加方式综述
|
摘要
原位稳定化修复技术因具有成本低、对周边环境影响小等优点,成为重金属污染土壤修复研究的热点。稳定剂的投加方式是影响修复效果的关键因素。文章介绍了直接喷洒、空心叉喷射、螺旋钻进注射及高压旋喷等4种稳定剂投加方式的基本原理,结合国内外案例分析了其适用性及优缺点,并展望了稳定剂投加方式的发展趋势。
In situ stabilization remediation technology has become a hotspot for the remediation research of the heavy metal polluted soil due to its low costs and less impact on the surrounding environment. Stabilizer injection method is the key factor affecting the remediation effect. The paper describes the basic principles of four kinds of stabilizer injection methods, such as direct spraying, hollow fork(excavator-mounted rake) ejection, rotary drilling injection and high pressure-rotating injection. In combination with the case at home and abroad, this paper analyzes their applicability, advantages and disadvantages, and prospects the development trend of the stabilizer injection method.
