利用微生物絮凝剂从厌氧发酵残留液中制备有机肥的肥效研究

Producing Fertilizer from Anaerobic Fermentation Slurry Adopting Microbial Flocculants and Its Fertilizer Efficiency

为了探讨生活垃圾厌氧发酵残留液经微生物絮凝剂絮凝沉淀后,沉淀物制备生物有机肥的可行性,试验采用实验室制备的微生物絮凝剂对生活垃圾厌氧发酵残留液进行絮凝处理,将沉淀物烘干制得生物有机肥,检测其有效成分并探讨其与植物生长状况的关系。试验结果表明,利用微生物絮凝剂絮凝生活垃圾厌氧发酵残留液后制备的有机肥肥效最好,对吊兰的生长有促进作用。

In this study, anaerobic fermentation slurry of domestic waste was treated with microbial flocculants producing sedimentation. And the sedimentation was dried and organic fertilizer was obtained. The active ingredients of the obtained fertilizer were detected, and its effect on plant growth was investigated. The result showed that the microbial flocculants treated fermentation slurry could produce high quality of organic fertilizer, and have a protnoting effect on growth of Chlorophytum.
