摘要: 以北京小红门污泥转运站的生活污泥为研究对象,探讨不同配比污泥基质处理对高羊茅和黑麦草生长的影响,为北京市合理利用城市生活污泥提供科学理论依据。采用土壤农化常规分析法对污泥基质进行分析,通过对比试验对2种草本植物的生长和生理指标进行比较。研究表明,污泥的施用明显改变了土壤的生化指标,进而影响了植物的生长发育。对于生污泥来说,随着配比比例的增加,高羊茅和黑麦草各项生长指标均呈现先增加后减少的变化规律;而对于污泥混合类型来说,50%生污泥和50%脱水泥饼更有利于草种的发芽和生长;当污泥配比比例超过60%时,会抑制植物的发芽和生长。另外,对于施用污泥的植物来说,其生理指标叶绿素含量明显增高,并且丙二醛含量也有显著变化。研究结果将为污泥矿山修复利用技术提供理论指导作用。

Abstract: In order to provide a scientific theory for the rational use of municipal sewage sludge in Beijing, sewage sludge of Xiaohongmen sludge transfer station was used as study material, the effects of different proportions of sludge treatment on the growth of Festuca arundinacea and Lolium were analyzed, soil conventional analytical methods were used to analyze the sludge medium, the growth and physiological indices of the two herbs were compared through the comparative test. The results showed that the application of sludge significantly altered the soil biochemistry index, then affected the growth and development of plant. The growth indicators of Festuca arundinacea and Lolium showed an “increase-decline” trend with the increase of the application of raw sludge. For the mixed sludge type, 50% raw sludge and 50% raw dewatered sludge cake were more conducive to the germination and growth of grass seed. When its proportion exceeded 60%, the sludge would inhibit the germination and growth of plant. In addition, the chlorophyll content was significantly higher under sewage sludge treatment, and the content of MDA also had significant change. The results could provide theoretical guidance for the use of sludge technology in mining rehabilitation.
