Invasive aquatic weed management is one of the biggest challenges in the field of solid waste management. Eichhornia crassipes, Pistia stratiotes and Hydrilla verticillata (L.f.) Royle pose some of the world's most noted aquatic weed problems. Previously reported studies on management of H. verticillata, a submersed aquatic plant, have shown that temporary removal, chemical treatment or biological control methods each have advantages and disadvantages. Removal programs that propose to compost harvested H. verticillata biomass may provide a novel technique to manage this issue. However, the properties of such compost as an agriculture resource are unclear. This study presents the different mix proportions of H. verticillata, cow dung and sawdust used for the composting of 550 L rotary drum composter. This work characterizes the biological, physicochemical, and respirometry properties of the various mixes over a 20-day composting period. The results suggest that the biomass of H. verticillata can be beneficially utilized to produce stable compost for potential use in agricultural systems.
入侵水生杂草管理是固体废物管理领域面临的最大挑战之一。凤眼蓝、大薸和黑藻（L.f.）是世界上一些最著名的水生杂草问题。以前关于水生植物黑藻管理的研究表明，临时清除、化学处理或生物防治方法各有优缺点。提出将收获的黑藻生物质堆肥的清除计划可能为解决这个问题提供了一种新的技术。然而，这种堆肥作为农业资源的性质尚不清楚。本研究介绍了用于 550L 转鼓式堆肥机堆肥的不同黑藻、牛粪和木屑混合比例。这项工作在 20 天的堆肥过程中对各种混合物的生物、物理化学和呼吸计量特性进行了表征。结果表明，黑藻的生物质可以被有益地利用来生产稳定的堆肥，以供潜在用于农业系统。
