Comparative study of ecological restoration technology of a mining brownfield

There are soil remediation, water remediation and phytoremediation that included in ecological rehabilitation technologies of mining brown field. Soil remediation technologies contain physical methods, chemical methods, microbiologic methods and Plant methods. Water ecological remediation can be realized by natural filtration cycle, chemical treatment which combined with project and reclaimed water treatment and soon. Phytoremediation contain vegetation buffer, hard rock reclamation affore station and hyper accumulation plants on the contaminated land. Comparing with China and foreign countries to find the gap and the best technical solution, by designing ecological remediation technology, artificial nature can be reconstructed on mining brownfield, and renaissance of brownfield can be realized.
