摘要/Abstract

摘要： 淋洗法是修复污染土壤的一种很有效的方法,是对污染土壤生物修复的一种补充,使污染土壤修复的系统化成为可能。淋洗法就是使用淋洗剂来清洗土壤,使土壤中污染物随淋洗液流出,然后对淋洗液及土壤进行后续处理,从而达到修复污染土壤的目的。而淋洗剂的选择是影响这一技术效率高低的主要因素之一。本文对目前淋洗剂的应用情况,作用机制进行了总结和评价。探讨了天然有机酸、生物表面活性剂等对环境影响小的淋洗液的应用前景。并根据“以废治污”的指导思想提出并分析了以柠檬酸废水和味精废水作为淋洗剂修复重金属污染土壤的可行性。

Abstract: Soil flushing is an effective method for the remediation of soil contaminated by heavy metals,and it is an important complement to the bioremediation of contaminated soil and makes remediation of contaminated soil more systematic.Flushing agents are the key to determine the washing efficiency.This paper reviews the status and mechanism of flushing agents.The application foreground of some new flushing agents such as organic acids and biosurfactants was discussed.At the same time,the feasibility of citric acid wastewater and monosodium glutamate wastewater used for remediation of heavy metal-contaminated soils was analyzed as well.

Key words: Vicia faba, Micro-nucleus ratio, Cd²⁺, Surfactant, Acid rain
