Scope

Main technical content: To meet the enhanced purification needs of nitrogen and phosphorus removal, heavy metal removal, and refractory organic pollutants in the effluent of wastewater treatment plants, comprehensive consideration is given to the requirements for collecting effluent from wastewater treatment plants, the principles of collection, water volume and water quality, the current analysis and investigation of effluent water quality, the implementation process of the deep purification system of effluent in artificial wetlands, purification objectives, basic principles, construction scale, site selection, overall layout, etc. A deep purification system of effluent in artificial wetlands is formed based on process flow, design parameters, process requirements, substrate selection, selection of aquatic higher plants, water collection and discharge, carbon supplementation of anaerobic fermentation liquids in artificial wetland plants, and secondary pollution prevention. Attention is also paid to the provisions for ancillary buildings and structures, construction and acceptance, and long-term operation and management, so as to achieve the goal of deep purification of effluent and reduce the types and total amount of pollutants discharged into receiving water bodies. Specific technical content includes: (1) Scope; (2) Normative reference documents; (3) Terms and definitions; (4) Design water volume and design water quality; (5) Overall requirements; (6) Deep purification system of effluent in artificial wetlands; (7) Ancillary buildings and structures; (8) Construction and acceptance; (9) Operation and management; (10) Appendix A (informative) Design parameters of artificial wetland units in the recommended process flow of deep purification system of effluent in artificial wetlands; (11) Appendix B (informative) Recommended wetland plants for deep purification system of effluent in artificial wetlands
