摘要

随着人口的增长和不受控制的垃圾填埋场的广泛使用，渗滤液构成了重大的环境风险，而传统的处理方法既昂贵又往往无效。本研究通过直接施用质量比分别为15、20、35和100 mg COD/g植物的渗滤液，进行了为期两个月的植物修复性能试验，将一种本地植物芒萁用于植物修复。结果表明，该植物在COD/g浓度为100 mg的渗滤液环境中均能存活，在COD/g浓度为15、20、35和100 mg的渗滤液环境中，其相对生长率分别为1.27%、1.42%、1.02%和0.88%。在相同质量比下，COD去除率分别为85.7%、93.4%、92.5%和63.6%。建立的动力学模型表明，COD的去除符合一级动力学。20 mg COD/g植株吸收率最高（0.0538 d - 1）。本研究首次深入评估了马来西亚生态系统中毛茛对渗滤液植物修复的作用，解决了修复研究中的一个关键空白。

Phyto-polishing of Leachate with Malaysian native bulrush: Pollutant removal and kinetics study

With growing populations and widespread use of uncontrolled landfills, leachate poses significant environmental risks, while conventional treatments are costly and often ineffective. This research presents the application of a native plant of Scirpus grossus for phytoremediation in a batch experiment through the direct application of leachate with mass ratios of 15, 20, 35 and 100 mg COD/g plant in phytoremediation performance test for two months. Results showed the plant could survive in leachate concentrations up to 100 mg COD/g plant, with relative growth rates of 1.27%, 1.42%, 1.02% and 0.88% for concentrations of 15, 20, 35 and 100 mg COD/g plant, respectively. The plant demonstrated effective pollutant removal, with COD removal rates of 85.7%, 93.4%, 92.5% and 63.6% for the same mass ratios. The kinetic model developed indicated that COD removal followed first-order kinetics. The highest absorption rate was found at 20 mg COD/g plant (0.0538 day^–1). This study offers the first in-depth assessment of S. grossus for leachate phytoremediation in Malaysian ecosystems, addressing a key gap in remediation research.

期刊介绍： Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include: •Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management; •Urban hydrology including sewer systems, stormwater management, and green infrastructure; •Drinking water treatment and distribution; •Potable and non-potable water reuse; •Sanitation, public health, and risk assessment; •Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions; •Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment; •Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution; •Environmental restoration, linked to surface water, groundwater and groundwater remediation; •Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts; •Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle; •Socio-economic, policy, and regulations studies.
