Reclaimed water application to vegetation restoration in mining area: Determination of water quality standards and optimization of moderate treatment technology

Water shortage severely restricts vegetation restoration of mining area in the northwest China. Moderate treatment reclaimed water is essential for improving local ecological environment. In this study, relevant quality standards issued by states and research results were comprehensively considered to propose a standard suitable area. The available domestic sewage mine was moderately treated hybrid biological reactor system nanofiltration membrane system, respectively. effluent meet requirement study. This study provides theoretical support
