Abstract

Improper solid waste management worldwide has increased the negative impacts of landfills due to the production of methane, carbon dioxide, and leachate wastewater. In the present work, granular activated carbon (GAC), zeolite (Ze), and hydrogen peroxide were used for the purification of landfill leachate. Emphasis was given to decreasing operational costs for a big-scale advanced oxidation process. Thus, the aim was to evaluate the effect of oxidant and catalysts dosages, and different highly basic pHs. Up to 95% of dark brown colour and 100% of turbidity from landfill wastewater were removed. Based on the experimental findings, it is suggested that an application of activated carbon and hydrogen peroxide in a dosage ratio between 1.7 and 2.0 would be economically attractive in terms of reduced operation costs.

沸石和活性炭对渗滤液澄清的催化作用

由于甲烷、二氧化碳和渗滤液废水的产生，世界范围内不适当的固体废物管理增加了垃圾填埋场的负面影响。采用颗粒活性炭(GAC)、沸石(Ze)和过氧化氢净化垃圾渗滤液。重点介绍了如何降低大规模高级氧化工艺的运行成本。因此，目的是评价氧化剂和催化剂的用量，以及不同的高碱性ph值的影响。去除垃圾填埋废水中高达95%的深褐色和100%的浑浊度。实验结果表明，从降低运行成本的角度来看，活性炭和过氧化氢的用量比在1.7和2.0之间具有经济上的吸引力。

期刊介绍： First published in 1995, the journal Environmental Research, Engineering and Management (EREM) is an international multidisciplinary journal designed to serve as a roadmap for understanding complex issues and debates of sustainable development. EREM publishes peer-reviewed scientific papers which cover research in the fields of environmental science, engineering (pollution prevention, resource efficiency), management, energy (renewables), agricultural and biological sciences, and social sciences. EREM’s topics of interest include, but are not limited to, the following: environmental research, ecological monitoring, and climate change; environmental pollution – impact assessment, mitigation, and prevention; environmental engineering, sustainable production, and eco innovations; environmental management, strategy, standards, social responsibility; environmental economics, policy, and law; sustainable consumption and education.
