摘　　要：研究了从一种槭科植物茎叶中提取的含多聚糖高分子絮凝剂(GNMF)在几种不同废水的处理中的应用。通过试验和现场应用,确定了GNMF在几种废水中的最佳工艺路线、pH值和处理的最佳配方,以及处理后的相关技术经济指标。结果表明,GNMF与传统的絮凝剂,如PAC、PAM相比,COD、SS、TP、TN和一些金属离子的去除率均可提高20%～30%,成本下降30%～40%,GNMF的提取和加工过程中无任何其他成分参与,几乎不存在二次污染,具有明显的经济效益和环境效益。The application of a natural polysaccharide flocculant （GNMF） extracted from a aceracenus plant stems and leaves to the treatment of different wastewater was studied. The optimal technological process, pH value, optimal formulation for treatment as well as related economic and technological indexes atter treatment were determined through test and application on spot. The results showed that, in comparison with traditional flocculants, such as PAC, PAM, the removal rate of COD, SS, TP, TN and some metal ions by GNMF could rise by 20%-30%; the cost lowered by 30%-40%. Owing to no other constituents to be dosed, in the course of GNMF extracted and processed, there is hardly secondary pollution; GNMF possesses obvious economic and environmental benefits.
