磁加载—碳纤维载体渠—增强型生态塘组合工艺在河道水质提升工程中的应用

Application of Magnetic Loading-Carbon Fiber Carrier Ditch-Enhanced Eco-pond Combination Technology in River Water Quality Improvement and Purification Project

针对宁夏吴忠市南干沟水体的污染特征,采用磁加载预处理、碳纤维载体渠和增强型生态塘组合处理工艺,分析了该工艺在河道水质提升净化工程中的应用情况。结果表明,磁加载-碳纤维载体渠-增强型生态塘组合工艺对河道来水中COD、TP、TN、NH3-N的平均去除率分别为64.64%、69.56%、67.10%、40.86%,排放浓度均达到《地表水环境质量标准》(GB3838-2002)Ⅳ类水标准。该工艺具有占地面积小、运行灵活、维护方便等特点,且吨水处理成本仅为0.19元,具有良好的经济效益和生态景观效益,因此在河道水质提升净化方面有着较好的发展和应用前景。

According to the pollution characteristics of water body in Nangan ditch,application of magnetic loading pretreatment,carbon fiber carrier ditch and enhanced ecological pond combined treatment technology in river water quality improvement and purification project was studied.The results show that the average removal rate of COD,TP,TN and NH3-N in river water by the combined process of magnetic loading,carbon fiber carrier ditch and enhanced ecological pond was 64.64%,69.56%,67.10%and 40.86%,respectively.The discharge concentration reached the four class of National Surface Water Standard.The process has the characteristics of small footprint,flexible operation and convenient maintenance,and the treatment cost per ton of water is only 0.19 yuan,which has good economic benefits and ecological landscape benefits.Therefore,it has a good development and application in the improvement and purification of river water quality.
