污染地下水原位处理方法:可渗透反应墙

可渗透反应墙法是 2 0世纪 90年代新兴的一种地下水污染原位处理方法 ,该方法目前在欧美已开始进入广泛的工程应用阶段。该方法与早期的一些处理方法相比 ,具有能持续原位处理、处理组分多、价格相对便宜等特点。本文系统介绍了该处理方法的基本原理、系统的结构构造和类型、处理机理和反应材料以及设计与施工等 ,为在我国开展该方法的研究和应用打下基础。

In situ remediation of contaminated ground water: permeable reactive barrier

Permeable reactive barrier is an approach developed recently to in situ remedy the contaminants of underground water system, it has widely been used in practical projects in America and Europe. The approach, compared to the earlier method, is characteristic with in situ remediation, good long term performance, many remediable contaminants and low costs. Remediation mechanism and the reactive materials, and design and construction of the system are introduced and analyzed in the paper to initiate a pilot study of the approach in China.
