【摘要】 用一种新型螺旋波式潜流人工湿地模型处理生活污水,使污水经过多次反复接触湿地基质,达到对污水中铵态氮、硝态氮、总氮的去除效果。试验通过对湿地土壤、水样中氮含量的测定分析,研究了螺旋波式潜流人工湿地模型主要组成部分截留氮的优势所在,为优化人工湿地模型内部构造及分析除氮机理提供了可靠的依据。更多还原

【Abstract】 The HW-SFCW with the helix wavy flow instead of the traditional flow to transact living sewage, made sewage get in touch with the wetland many times and improve the dfficiency in elimination NH4+-N,NO3-N,TN. The experiment studied the amount of nitrogen in soil and sewage, analyzed the predominance of the HW-SFCW in elimination nitrogen.更多还原
