小型湖泊重金属污染应急处理与修复研究

重金属元素对水体和土壤环境日趋严重的污染和破坏，严重威胁着人类健康。该文采用环境调水法修复小型湖泊重金属污染，检测不同修复时间段内的水体与底泥重金属镉含量，分析在该工艺运行模式下对重金属的修复效果。结果表明：（1）通过喷洒生石灰后，水体中镉含量会明显减少；（2）通过调水修复后，水体中镉浓度达到修复目标，湖泊底泥中重金属镉含量经修复后也大幅度减少。说明调水引流修复方法对修复湖泊中水体与底泥污染有显著效果，具有一定的可行性，能够为小型湖泊重金属污染应急事件的治理与修复提供重要依据与经验。

Study on Emergency Treatment and Remediation of Heavy Metal Pollution in Small Lake

The pollution of heavy metal is becoming increasingly serious;it is a serious threat to human health.Through the study on the repair of the pollution of heavy metals in small lakes on emergency treat？ment of heavy metal polluted by environment after water transfer law,detection of different repair period of water and sediment heavy metal cadmium content,analysis the effect of remediation for heavy metal in the process operation mode.The results showed that：（1）significantly reduce the content of cadmium in water will reach the target through the water diversion by spraying lime;（2）repair after the repair water concen？tration of cadmium,cadmium content in sediments of lakes after the repair is greatly reduced. The water transfer drainage repair method to repair in the lake water and sediment pollution has remarkable effect , has the certain the feasibility,can provide an important basis and experience for the treatment and remedia？tion of heavy metal pollution in small lakes emergency events.
