Abstract

Due to the impact of mining activities, domestic sewage in mining areas contains heavy metals, high salt content, and refractory organic matter, making its treatment significantly more difficult than urban sewage. This article systematically reviews the research progress in this field in recent years, indicating that the bio-physicochemical combined process has become a mainstream technology. The treatment efficiency can be improved through microbial agent enhancement, membrane material modification, and ecological restoration. However, heavy metal inhibition and low-temperature inactivation remain core challenges. In the future, focus should be placed on resource recovery and intelligent operation and maintenance to promote sustainable treatment of mining area sewage.
