人工湿地对高盐废水尾水的深度处理研究

Research on Advanced Treatment of High-salt Wastewater Tail Water in Constructed Wetland

本项目主要针对高盐废水尾水的深度处理展开研究,从技术先进性和可能存在的问题及解决方案等角度分析项目的可行性。系统进水主要特征为高盐度,废水可生化性差,水质波动较大。进水满足标准后,经过人工湿地系统处理后,出水的COD、氨氮和总磷可以达到《地表水环境质量标准》(GB 3838-2002)Ⅳ类标准。

This project focuses on the advanced treatment of high-salt wastewater tail water, and analyzes the feasibility of the project from the perspective of technological advancement and possible problems and solutions. The main characteristics of the system influent are high salinity, poor biodegradability of wastewater, and large fluctuations in water quality. After the influent water meets the standards, after being treated by the constructed wetland system, the COD, ammonia nitrogen and total phosphorus of the effluent can meet the Class Ⅳ standards of the Environmental Quality Standards for Surface Water(GB 3838-2002).
